More Than 500,000 Industrial Robots Shipped in 2023

Overall global industrial robot shipment volumes exceeded 500,000 units in 2023, according to global market research firm Interact Analysis. This was a similar level to that seen in 2022 but the average price of industrial robots decreased last year. After a record high in 2021, 2023 reached a low point in terms of revenues and shipments but the long-term forecast remains positive. The global industrial robot market is expected to grow on average, by 3.7% per year between 2024 and 2028.
Taking a look at the market by industry and region, sales of industrial robots to the automotive industry in the Americas faced significant pressure in 2023, resulting in sluggish growth for this segment of the market – one of the largest downstream industries for industrial robots in the region. Mexico in particular has high dependence on the automotive industry, therefore creating a greater impact on industrial robot sales in the region. On the whole, growth of industrial robots in the Americas plummeted by 17.3% in 2023; compared with APAC, which saw a slight increase in growth, and EMEA, which remained stable.
The American markets accounted for around 17% of global industrial robot revenues compared to 62% for APAC and 22% for EMEA. The industrial robot market enjoyed strong growth in the Americas during the immediate post-COVID period in both the automotive and non-automotive industries, where manufacturers were continually looking for ways to improve their production processes and reduce manufacturing costs by adopting the technology.


The top three most common applications – material handling, welding and assembly – accounted for over 70% of industrial robot market revenues in 2023, with material handling accounting for one third on its own. This common application is particularly dominant in the Americas and Europe. The American market has the highest market concentration globally, where the top 5 suppliers shared nearly 80% of revenues and over 2/3 of unit shipments.
Maya Xiao, research manager at Interact Analysis, commented, “The average price per unit of an industrial robot is on a downward trajectory, following a rise for two consecutive years, and we expect a price decline of around 3% per year between 2024 and 2028. The COVID-19 pandemic coupled with high energy prices and inflation caused an average price increase in 2022. We originally expected robot prices to decrease again in 2023, but ongoing supply chain and inflation issues resulted in prices creeping up to levels close to those seen in 2022. This increased ‘price effect’ was also partially due to the market trend towards heavy payload robots, which are materially a more expensive product.
“It is important to note that our robotics forecasts are underpinned by the Interact Analysis Manufacturing Industry Output (MIO) Tracker. We can see from our data that the growth profile for industrial robots reflects the manufacturing slowdown during the pandemic era and the subsequent downturn in 2023. If we take a look at the manufacturing output figures for China, Europe and the Americas, the historic manufacturing contractions are synonymous with the decline in growth for the industrial robot market that we have observed in recent years.”

Historical Development of Automatic Control Principles

Historical development

The earliest automation control can be traced back to ancient China’s automation timers and leakage guide cars, while the widespread application of automation control technology began during the Industrial Revolution in Europe. Watt, a British inventor, applied the principle of feedback while inventing the steam engine and invented the centrifugal governor in 1788. When the load or steam supply changes, the centrifugal governor can automatically adjust the opening of the intake valve to control the speed of the steam engine. [2]
More than 150 years ago, the first generation of process control systems was based on the pneumatic signal standard of 5-13psi (pneumatic control system PCS), Pneumatic Control System)。 A simple on-site operation mode, control theory has initially formed, and there is no concept of a control room yet.
The second generation process control system (analog or ACS, Analog Control System) is based on current analog signals of 0-10mA or 4-20mA. This significant advancement firmly dominated the entire field of automatic control for a full 25 years. It marks the arrival of the era of electrical automatic control. The control theory has made significant development, and the establishment of the three major control theories has laid the foundation for modern control; The establishment of control rooms and the mode of separating control functions have been used to this day.
The Third Generation Process Control System (CCS) began the application of digital computers in the 1970s, which gave rise to significant technological advantages. People were the first to use it in the fields of measurement, simulation, and logic control, leading to the emergence of the Third Generation Process Control System (CCS), Computer Control System)。 This is known as the third-generation process control system, which is a revolution in the field of automatic control. It fully leverages the strengths of computers, and people generally believe that computers can do everything well. Naturally, a central control computer system called “centralized control” emerged. It should be pointed out that the signal transmission system of the system is still mostly using 4-20mA analog signals. However, soon after, it was discovered that with the concentration and reliability of control, the danger of losing control has also increased, and even a slight mistake can paralyze the entire system. So it quickly developed into Distributed Control Systems (DCS).
The fourth generation process control system (DCS): With the rapid development of semiconductor manufacturing technology, the widespread use of microprocessors, and the significant increase in computer technology reliability, the fourth generation process control system (DCS) is currently widely used. Its main feature is that the entire control system is no longer just a single computer, but a control system composed of several computers, intelligent instruments, and intelligent components. So decentralized control became the most important feature. Another important development is that the signal transmission between them not only relies on 4-20mA analog signals, but also gradually replaces analog signals with digital signals.
The fifth generation process control system (FCS): FCS evolved from DCS, just like DCS evolved from CCS, with a qualitative leap. The development of “decentralized control” to “on-site control”; The transmission of data adopts a “bus” method. But the real difference between FCS and DCS is that FCS has a broader development space. Due to the continuous improvement of traditional DCS technology, the communication network only reaches the level of on-site control station at the lowest end. The connection between on-site control station and on-site detection instruments and actuators still uses one-to-one transmission of 4-20mA analog signals, which is costly, inefficient, and difficult to maintain. It cannot fully realize the potential of on-site instrument intelligence and achieve comprehensive monitoring and deep management of the working status of on-site equipment. The so-called fieldbus is a fully digital, bidirectional transmission, multi node branch structure communication link that connects intelligent measurement and control equipment. Simply put, traditional control is a loop, while FCS technology involves various modules such as controllers, actuators, detectors, etc. hanging on a bus to achieve communication, and of course, transmitting digital signals. The main buses include Profibus, LonWorks, etc.


1. 1940s – early 1960s:
Demand driving force: market competition, resource utilization, reducing labor intensity, improving product quality, and adapting to the needs of mass production. Main features: This stage is mainly a single machine automation stage, characterized by the emergence of various single machine automation processing equipment, and the continuous expansion of applications and development towards depth. Typical achievements and products: CNC machine tools for hardware CNC systems.
2. In the mid-1960s to early 1970s:
Demand driving force: Market competition intensifies, requiring fast product updates, high product quality, and adapting to the needs of large and medium batch production and reducing labor intensity. Main features: This stage is mainly marked by automatic production lines, which are characterized by the emergence of various combination machine tools and combination production lines on the basis of single machine automation. At the same time, software numerical control systems have emerged and been used for machine tools. CAD, CAM and other software have begun to be used in actual engineering design and manufacturing. At this stage, hardware processing equipment is suitable for large and medium batch production and processing. Typical achievements and products: an automatic production line used for drilling, boring, milling and other processing.
3. From the mid-1970s to present: Demand dynamics: Changes in the market environment have made common problems in multi variety, medium and small batch production increasingly severe, requiring automation technology to develop in its breadth and depth, making its related technologies highly integrated and exerting overall optimal efficiency. Main features: Since American scholars first proposed the concept of CIM in the early 1970s, there have been significant changes in the field of automation. Its main characteristics are that CIM has gradually been accepted as a philosophy and method by people; CIM is also a corresponding technology for implementing integration, integrating dispersed and independent unit automation technologies into an optimized whole. The so-called philosophy is that enterprises should analyze and overcome existing “bottlenecks” based on their needs, in order to achieve the ideological strategy of continuously improving their strength and competitiveness; As the corresponding technology for implementing integration, it is generally believed to be: data acquisition, distribution, and sharing; Network and communication; Workshop level equipment controller; The specifications, standards, etc. of computer hardware and software. Meanwhile, parallel engineering, as a business philosophy and work mode, has been applied and active in the field of automation technology since the late 1980s, and will further promote the integration of unit automation technology. Typical achievements and products: CIMS factory, flexible manufacturing system (FMS).
With the introduction of new achievements in modern applied mathematics and the application of electronic computers, in order to adapt to the development of aerospace technology, automatic control theory has entered a new stage – modern control theory. The main research focuses on the optimal control problem of multivariable variable parameters with high performance and precision, using the state space method based on the state. At present, the theory of automatic control is still developing, and intelligent control theory based on control theory, information theory, and bionics is deepening.
In order to achieve various complex control tasks, the controlled object and control device must be connected in a certain way to form an organic whole, which is the automatic control system. In automatic control systems, the output of the controlled object, also known as the controlled quantity, is a physical quantity that requires strict control. It can be required to maintain a constant value, such as temperature, pressure, or flight path; The control device is the overall mechanism that applies control to the controlled object. It can use different principles and methods to control the controlled object, but the most basic one is a feedback control system based on feedback control principles.
In a feedback control system, the control effect exerted by the control device on the controlled device is obtained from the feedback information of the controlled quantity, which is used to continuously correct the deviation between the controlled quantity and the control quantity to achieve the task of controlling the controlled quantity. This is the principle of feedback control.

Clean your beloved car

As an experienced driver who has been driving for 12 years, I have witnessed many car destruction behaviors.
We all know that cars are money burning goods. Buying a car is easy, but maintaining it is difficult. One mistake can cause trouble for your beloved car.
Among them, the most easily overlooked behavior is the seemingly normal one of washing cars.
The other day I chatted with some old irons, and they laughed at me and said, “Your car is too dirty, isn’t it? It’s like a mud monkey, and you don’t know how to wash it?” That’s just a way of discouraging, almost making me unable to resist saying, “It’s none of your business.”.
But when I thought about it, they were also good for me and patiently explained it, which surprised them all.
This has to start with washing the car.
As ordinary people, there are only a few ways to wash cars: either go to a car wash shop, go to a gas station, or wash them at your doorstep.
If you go to a car wash shop, it’s the most worry free. For one or two hundred yuan, the car can be washed just like new, and the engine compartment can be cleaned for you.
However, for us ordinary people, washing it once a month is considered a luxury.
Going to the gas station to wash the car may be convenient, but the car washing machine is called a damaged car.
Some gas station car washing equipment has several rolling wheels jumping up and down, and over time, the car paint is brushed off.
Not to mention those car window seals and wipers, they need to be replaced with new ones after a few uses. This car washing method, breaking the sesame seeds and losing the watermelon, is not cost-effective at all.


So many Laotie choose to wash their cars at home.
Not only does it save money, but it’s also convenient. You can handle it with just a bucket of water and a towel, and it can also show off and enjoy car washing.
Washing the car at this doorstep is mainly time-consuming and laborious, but most people think that washing it at home is better than washing it outside, at least not damaging the car paint.
But the fact is, washing a car at home is the easiest way to ruin it!
Let’s think about it. The car runs outside every day, covered in dust and mud. If you use a dirty towel to wipe it off, isn’t that sandpaper to polish the car paint?
Even if you clean the towel and rub against the car in an unclean area, it will still damage the car paint.
Over time, the car paint has been washed to a dull and dull finish, and to restore its shine, one has to spend money waxing it.
There is also the windshield, which is covered with a layer of expensive insulation film. If you accidentally rub a dirty towel and leave a few scratches, you will be at a great loss. Fix it, ranging from a few hundred to thousands. Think about it, is this washing the car or the money?
We wash the car at home, and the conditions are not professional either.
Without a suitable water gun and insufficient water pressure, the stains on the car paint cannot be cleaned; Without a professional car wash solution, the residual soap and water may corrode the car paint; Even after washing, it cannot be completely dried. As soon as the water droplets evaporate, the stains settle back onto the car.
It’s like renovating a used car, it’s strange if you don’t damage the car after washing it.
In contrast, professional car wash shops are different. The equipment is professional, the personnel are well-trained, and the car wash solution is carefully selected.
Before washing the car, first flush it with a high-pressure water gun, and the sediment will almost fall off. Then apply foam and towel, which is called a safety.
Car wash towels are also specially air dried and disinfected, so they won’t harm your car again.
So old Ties, if you have the habit of washing your car at home, I would advise you to change it as soon as possible. It’s better to keep dust and dust on than to waste it on your own. If you want to wash the car, it’s better to go to a professional store to do it. Don’t think it’s too expensive. Spending that little money would still allow your car to serve for a few more years, what a good deal.
However, on the other hand, even if we don’t wash the car, there are actually many behaviors of damaging it when we use it on a regular basis. For example, driving a car in place for half an hour or driving at low speeds for a long time without being willing to step on the accelerator are all misconceptions about loving a car, and over time, they can also cause harm to the car.
Like the hot car in situ, many old irons think that this is to protect the engine, but in fact, it is totally in practice. Now that it’s not an old-fashioned car, why should it be so hot for so long? Half a minute is enough. The hotter your car is, the more carbon accumulates, and the more fuel is wasted, which is harmful but not beneficial.
When driving at low speeds, I dare not give fuel, thinking that I am taking care of the engine, but little do I know that the gearbox is crying and fainting in the toilet. Long periods of high and low gears not only consume fuel, but also the gearbox cannot afford it. It has learned your driving habits, and with a sudden step, you can activate its “diabetes insipidus mode”.
So there is a way to love a car and a skill to use it. When it’s time to wash, find a professional to do it. When it’s time to heat up the car and speed up, don’t hesitate. This way, your car can live a long and healthy life, and spend more years with you.

Historical Development of Automatic Control Systems

Automatic control system refers to the use of some automatic control devices to automatically control certain key parameters in production, so that when they deviate from the normal state due to external interference (disturbance), they can be automatically adjusted and returned to the numerical range required by the process. Various process conditions cannot remain unchanged during the production process. Especially in chemical production, most of them are continuous production, and various equipment are interrelated. When the process conditions of one equipment change, it may cause some parameters in other equipment to fluctuate more or less, deviating from normal process conditions. Of course, automatic adjustment refers to the absence of direct human involvement.
After more than 20 years of development, the manufacturing industry of industrial automatic control system devices in China has made significant progress, especially since the 1990s, the output of China’s industrial automatic control system device manufacturing industry has maintained an annual growth of over 20%. In 2011, the manufacturing industry of industrial automatic control system devices in China achieved remarkable results. The total industrial output value completed throughout the year was 205.604 billion yuan; The product sales revenue was 199.673 billion yuan, a year-on-year increase of 24.66%; The total profit achieved was 20.284 billion yuan, a year-on-year increase of 28.74%. Domestic automatic control systems have successively achieved breakthroughs in the fields of thermal power, fertilizer, and oil refining.
The main players in China’s industrial automation market are software and hardware manufacturers, system integrators, and product distributors. In the field of software and hardware products, the mid to high end market is almost entirely monopolized by well-known foreign brand products, and this situation will continue to be maintained; In the field of system integration, multinational corporations occupy the high-end of the manufacturing industry, and companies with deep industry backgrounds take the initiative in related industry system integration businesses. System integration companies with rich application experience are highly competitive.


In the industrial automation market, there is a mismatch between supply and demand. What the customer needs is a complete electrical control system that can meet their own manufacturing process, while the supplier provides various standardized device products. There are significant differences in electrical control among different industries, and even within the same industry, customers have varying demands due to their different processes. The contradiction between supply and demand has created development space for the industrial automation industry.
China has the world’s largest market for industrial automatic control system devices. Traditional industrial technology transformation, factory automation, and enterprise informatization require a large number of industrial automation systems, and the market prospects are broad. Industrial control automation technology is developing towards intelligence, networking, and integration. Based on the promising development prospects of industrial automation control, it is expected that the market size of the industrial automation control system device manufacturing industry will exceed 350 billion yuan in 2015.
With the continuous intensification of competition in the industrial automatic control system device manufacturing industry, mergers and acquisitions and capital operations among large industrial automatic control system device manufacturing enterprises are becoming increasingly frequent. Excellent domestic industrial automatic control system device manufacturing enterprises are paying more and more attention to research on the industry market, especially in-depth research on the industrial development environment and product buyers.

PLC detailed introduction

The English name for programmable logic controller is Programmable Logic Controller, which was abbreviated as PC in the 1970s and 1980s. Due to the development of personal computers, also known as PCs, in the 1990s; In addition, the concept of programmable logic covers a wide range, so AB Company in the United States first named programmable logic controllers (PLCs). For convenience, PLC is still referred to as programmable logic controller. Some people refer to a system composed of programmable controllers as a PCS programmable control system, emphasizing that the manufacturer of programmable controllers has already provided people with a complete system.
The Development History of PLC
In 1968, General Motors of the United States proposed a requirement to replace relay control devices. The following year, Digital Corporation of the United States developed the first generation of programmable controllers, which met the requirements of GM’s assembly line. With the development of integrated circuit technology and computer technology, there are already fifth generation PLC products.
In the manufacturing industry characterized by changing geometric shape and mechanical properties, as well as in the process industry characterized by converting raw materials into products through physical and chemical changes, in addition to feedback control mainly based on continuous variables, there are a large number of open-loop sequential control mainly based on switch variables in the manufacturing industry, which operates in sequence according to logical conditions; In addition, there are controls for chain protection actions that are independent of sequence and timing and follow logical relationships; And a large number of state variables such as switch quantity, pulse quantity, timing, counter, analog quantity exceeding limit alarm are mainly collected and monitored for discrete quantity data. Due to these control and monitoring requirements, PLC has developed into a product that mainly replaces relay circuits and performs sequential control. Over the years of production practice, a tripartite balance has gradually emerged between PLC, DCS, and IPC, as shown in Table 1. Other single circuit intelligent regulators also account for a certain percentage in the market.
The period from the 1980s to the mid-1990s was the fastest growing period for PLC, with an annual growth rate of 30-40%. Due to the advancement of simulation capabilities and network functions of PLC machines, they have squeezed out a portion of the DCS market (process control) and gradually monopolized industries such as wastewater treatment. However, with the emergence of industrial PCs (IPC), especially the development of fieldbus technology, IPC and FCS have also squeezed out a portion of the PLC market. Therefore, the growth rate of PLC is generally slowing down. There are over 200 manufacturers worldwide producing over 300 varieties of PLC products, mainly used in industries such as automotive (23%), grain processing (16.4%), chemical/pharmaceutical (14.6%), metal/mining (11.5%), pulp/paper (11.3%), etc.


Market situation of PLC
There are about 30 domestic PLC production plants, but they have not formed a significant production capacity and branded products. Some of them are produced through imitation, incoming assembly, or “OEM” methods. Therefore, it can be said that PLC has not formed a manufacturing industry in China. As a product with no cutting-edge technical difficulties in terms of principles, technology, and processes, with hard work, it can form a manufacturing industry.
In terms of PLC applications, China is very active, with approximately 100000 new sets of PLC products invested each year and an annual sales revenue of 3 billion yuan. The industry is also widely used. However, compared to other countries, there is still a need to increase investment in the application of mechanical processing and production lines.
The market potential of PLC is enormous, not only in China, but also in industrialized Japan. Surveys have shown that the proportion of electromechanical integrated products matched with PLC accounts for 42%, and 24% are controlled by relays and contactors. So, there are still many occasions where PLC needs to be applied, and this is even more so in China.
From the perspective of technological innovation, China’s large and medium-sized enterprises still need to vigorously develop CIMS (Computer Integrated Manufacturing System), and form FMS flexible manufacturing systems in mechanical manufacturing plants. PLC is the foundation, so the PLC market is broad.
PLC has the advantages of stability, reliability, low price, complete functions, flexible and convenient application, and easy operation and maintenance. This is the fundamental reason why it can sustainably occupy the market. Below, we will focus on several issues and study its development trends.

What does the industrial control industry do

Industrial automation control
The industrial control industry, also known as industrial automation control, mainly utilizes electronic and electrical, mechanical, and software combinations to achieve automation, efficiency, precision, and controllability and visibility in factory production and manufacturing processes through computer technology, microelectronics technology, and electrical means. This field is a general term for tools involved in the detection and control of production processes, their electromechanical equipment, and process equipment, which have computer properties and characteristics, such as having a CPU, hard disk, memory, peripherals and connections, and equipped with real-time operating systems, control networks and protocols, computing power, and friendly human-machine interfaces.
The industrial control industry has a wide range of application scenarios, including factory automation (FA) and process automation (PA). Factory automation is mainly applied in discrete industries, such as textile machinery and packaging machinery, with a focus on precise control; And process automation mainly controls continuous variables, focusing on controlling stability, and is applied in industries such as metallurgy and chemical industry.


The functions of industrial control products can be mainly divided into three levels: control layer, driver layer, and execution layer. The control layer realizes the analysis, processing, and allocation of tasks; The driver layer decodes the tasks of the control layer into signals that can be recognized by motors, valves, etc; The execution layer executes the corresponding tasks.
The development of the industrial control industry is closely related to the manufacturing industry and has strong pro cyclical characteristics. With the increase in investment activities in the manufacturing industry, the demand in the industrial control industry has also grown. In addition, the industrial control industry is closely related to the macroeconomic operation, and the market size of industrial control products is greatly affected by economic fluctuations.
In summary, the industrial control industry improves the efficiency and quality of industrial production through automation technology, which is an important upstream industry in the manufacturing industry and plays a key role in promoting industrial modernization and intelligent development.

The Customs of the Dragon Boat Festival in China

Eating zongzi during the Dragon Boat Festival is one of the festival customs. Zong, or “zongzi”, commonly known as “Zongzi”, is one of the “zongzi”. “籺” is a tribute used to worship gods and ancestors during festivals. There are many varieties of “籺”, and different festivals will make different dishes. Making dishes to worship gods and ancestors is an ancient custom. The main ingredients of zongzi are rice, filling, and bamboo leaves (or new leaves). Due to the different eating habits in different places, Zongzi has formed a northern and southern flavor; In terms of taste, Zongzi can be divided into salty zongzi and sweet zongzi.
The custom of eating zongzi during the Dragon Boat Festival has been prevalent in China for thousands of years and has become one of the most influential and widely covered folk dietary customs of the Chinese nation, and has been passed down to Korea, Japan, and Southeast Asian countries.
historical origin
Zongzi, a type of rice dumpling, has a long history and a variety of patterns. The ancients boiled rice (or millet) wrapped in new leaves, bamboo leaves, or reed leaves, with sharp edges resembling the shape of a heart, called zongzi (zongzi). It is an ancient traditional custom to worship gods and ancestors during festivals and festivals. The Classic of Mountains and Seas – Nanshan Jing: The head of Mount Que, from the Zhaoyao Mountain to the Jiwei Mountain, covers ten mountains, 2950 miles, with a bird body and a dragon head in its divine form. The ritual of his ancestral temple: Mao, buried with a piece of jade; Do not use rice, one wall, rice and white Ying as mats.
Zongzi was originally used as a tribute to worship gods and ancestors during the Dragon Boat Festival; By the Jin Dynasty, it had already been popularized throughout the country and officially designated as food for the Dragon Boat Festival. In the “Fengtu Ji” of the Jin and Zhou dynasties, it is said that “during the midsummer Dragon Boat Festival, we cook cornstarch.” The cornstarch is wrapped in zizania leaves (zizania leaves) to form cow horns, known as “cornstarch.”; Using bamboo tubes to seal and bake rice, it is called “tube zongzi”. At the end of the Eastern Han Dynasty, millet was soaked in ash water from plants and trees. Due to the presence of alkali in the water, millet was wrapped in bamboo leaves in a square shape and cooked to become Guangdong alkaline water zongzi.
evolution
Zongzi, also known as “corn millet”, “drum dumplings”, etc. The original work of the word “Zong” is “糉񌊉񌊉񌊉񌊉񌊉񌊉񌊉秚秚秚秚秚秚秚秚秚秚秚秚秚秚秚. In the “Fengshi Ji” written by Zhou Chu, the Prefect of Xinping in the Western Jin Dynasty, the term “Jiaoshu” was explicitly mentioned: “In the middle of summer, at the end of the fifth year, Fang Boxie reached the extreme. Enjoying Jiaoshu, the turtle scales were Shunde.”.
During the Jin Dynasty, zongzi was officially designated as a food for the Dragon Boat Festival. According to the “Yueyang Fengtu Ji” written by the local people, “It is common to wrap millet with wild rice leaves and cook them until they are ripe. They are eaten from May 5th to the summer solstice, and are called zongzi and millet.” During the Northern and Southern Dynasties period, mixed zongzi appeared. The rice is mixed with animal meat, chestnuts, red dates, red beans, etc., resulting in an increase in variety. Zongzi is also used as a gift for communication.
By the Tang Dynasty, Zongzi rice had become “as white as jade”, and its shape appeared cone and diamond. The Japanese literature records “Zongzi of the Tang Dynasty”. During the Song Dynasty, there was already “preserved rice dumplings”, which means that fruits were added to the rice dumplings. The poet Su Dongpo once said, “I see yangmei in the zongzi.”. At this time, there were advertisements made with Zongzi stacked into pavilions and wooden carts, indicating that eating Zongzi was very fashionable in the Song Dynasty.
During the Ming and Qing dynasties, Zongzi became an auspicious food. According to Qu Dajun’s “Guangdong New Language” in the Qing Dynasty, “From the first day of the fifth lunar month to the fifth day, the millet is tied with zongzi heart grass and rolled with new leaves.” It is said that at that time, all the scholars who took the imperial examination had to eat the “brush zongzi” specially made by their families before going to the examination room, which looked thin and long like a brush, homophonic with “must hit”, in order to win praise.
At the beginning of May every year, Chinese people soak glutinous rice, wash the leaves, and wrap Zongzi at home, with a wide variety of designs and colors. From the filling, Beijing jujube zongzi, which is often wrapped with small dates in the north, is more common; In the south, there are bean paste, fresh meat, ham, egg yolk and other fillings, with Zongzi in Jiaxing, Zhejiang as the representative.

Local characteristics

Eating zongzi during the Dragon Boat Festival is a widely popular traditional custom in China. The main ingredients of zongzi are rice, filling, and bamboo leaves (or new leaves). The “plant leaves” used to wrap Zongzi are collectively called zongzi leaves. The traditional form of Zongzi is a triangle, which is usually named according to the inside. The types of Zongzi can be divided into two categories: salty and sweet Zongzi; From the filling of Zongzi, salty zongzi include meat zongzi, bacon egg yolk zongzi, mushroom zongzi, abalone zongzi, lotus seed zongzi, etc., and sweet zongzi include fruit zongzi, bean paste zongzi, jujube zongzi, taro zongzi, etc; In addition to these, there are also some people in certain regions who love to eat alkaline water zongzi and white zongzi. Zongzi in the north is mostly simple white rice, red beans, dates, dipped in sugar. In the south, Zongzi is rich in taste. Fresh meat, ham, clams, egg yolks, bean paste, ribs, honey dates, lotus, etc. can all become delicious in Zongzi. The shapes often reflect regional characteristics.
Zongzi: Zongzi is a long and thin quadrangle, with fresh meat, jujube paste, bean paste, lard with sand and other varieties. It has the characteristics of exquisite ingredients and fine production.
Zongzi: a representative variety of Zongzi in the south, Zongzi Zongzi has a unique shape, with a square front and a sharp corner raised at the back, like an awl. In addition to fresh meat zongzi, ham zongzi, clam shaped zongzi, and bean paste zongzi, there are also egg yolk zongzi made with salted egg yolks.
Zongzi: Zongzi is a square cone wrapped by banana leaves and weighs about half a kilogram. There are salted egg yolks, Grilled pork, bacon, braised chicken wings, etc. in glutinous rice. When hot zongzi is peeled, it has the fragrance of banana and glutinous rice first, followed by the fragrance of meat and eggs.
Minnan Zongzi: Pork dumplings and alkaline dumplings are famous at home and abroad. Braised meat zongzi is exquisitely crafted, with high-quality glutinous rice being a must-have. Three layers of pork are chosen, marinated first until fragrant and rotten, and then mixed with shiitake mushrooms, shrimp, lotus seeds, braised meat soup, white sugar, and other ingredients. When eating, it is dipped in various seasonings, making it sweet and tender.
Zongzi: People in Zongzi are fond of spicy food, so they can also be sweet and spicy. The hot dumplings in Sichuan are made by soaking glutinous rice and red beans for 5 to 6 hours, pouring out water, adding pepper powder, Sichuan salt, monosodium glutamate and a little bacon, and wrapping Zongzi leaves into 60 grams of quadrangular dumplings.
Zongzi: The representative variety of Zongzi in the north, Zongzi Zongzi is a large, oblique quadrangle or triangle. Most of the products available in the market are glutinous rice dumplings. In rural areas, it is still customary to eat rhubarb rice dumplings. Sticky and fragrant, it has a special flavor. Most Zongzi in Beijing use red dates and bean paste as fillings, and a few also use preserved fruit as fillings.

Regardless of physical condition, randomly supplement, the more supplement, the more deficiency!

With the rapid development of society, now everyone has some degree of illness!
The pressure of life is increasing, and the number of sub healthy people is also increasing. According to relevant data, only 5% of the world’s truly healthy population is in sub healthy state, and the total population in sub healthy state accounts for 75%.
Among them, the sub healthy population in China has already reached 70%, which means that more than 900 million Chinese people are in a sub healthy state. In order to maintain health, many people will use various methods to supplement.
However, if one starts to supplement without understanding their physical condition, it may have the opposite effect and make the body even weaker.

Therefore, when we nourish and regulate our bodies in daily life, we must follow our own physical constitution.
The first step in health preservation: Identify physical constitution!
Physical constitution refers to the comprehensive and stable characteristics of the human body’s morphological structure, physiological functions, and psychological state displayed under the combined effects of innate genetics and acquired environment.
The Chinese Society of Traditional Chinese Medicine released the “Classification and Determination of Traditional Chinese Medicine Constitution” on March 26, 2009, which clearly stated that currently, the most authoritative classification of traditional Chinese medicine constitution is 9 types, including 1 mild constitution and 8 biased constitution.
The peaceful constitution represents a healthy physiological state, while the other eight biased constitutions – qi deficiency, yang deficiency, yin deficiency, phlegm dampness, damp heat, qi stagnation, blood stasis, and intrinsic qualities – are considered as manifestations of sub healthy states.
What are the manifestations of sub-health status? Sudden lack of energy, fatigue, lethargy, distraction, chest tightness, palpitations, insomnia, pain in various parts of the body, dizziness, menstrual disorders, and sexual dysfunction are common manifestations of sub-health.
It is not difficult to find in daily life that some people do not gain weight no matter how they eat, while others gain weight as soon as they eat; Some people are not afraid of cold or hot, while others often feel cold; Some people have delicate skin, while others have many skin problems.
The differences in these situations are actually closely related to an individual’s physical condition!
Traditional Chinese medicine identifies and divides a person’s physique based on their body shape, skin color, posture, speech and behavior, and their ability to adapt to the external environment.
If you want to have a healthy physique, the most crucial thing is to understand and determine your physical type, and then choose targeted and effective health plans that suit you, in order to effectively adjust your body condition and achieve the best health results.
This can not only effectively improve one’s health condition, but also achieve twice the result with half the effort in the process of health preservation.
If the body is sick, the tongue will first “report”
We have the most sensitive organ in our body, and almost all systemic diseases can be most intuitively reflected on this organ, which is the tongue.
By combining the tongue images of traditional Chinese medicine with various other body information, we can comprehensively judge and identify our physical constitution, which is the relatively stable inherent characteristic of each of us.
In history, many medical classics, such as “Su Wen”, can be treated with tongue to tongue conversion; The divine physician Hua Tuo died with his tongue curled black; The Golden Chamber states that the tongue can be lowered with yellow color; The Treatise on Cold Damage includes a white tongue with slippery coating and a dry and urgent tongue; The “Tongue Diagnosis and Correction” discusses that distinguishing the tongue is better than diagnosing the pulse, and also emphasizes the importance of tongue diagnosis.
In the diagnosis and treatment of traditional Chinese medicine, “tongue image” is an indispensable part, reflecting a person’s physical condition, such as cold and heat deficiency and excess, disease severity, qi and blood rise and fall, and disease location.
Modern instruments may not be able to detect various negative emotions in humans, but traditional Chinese medicine constitution identification can do so, and the biased state of various constitutions is actually the internal root of disease disorders.
Among them, tongue diagnosis is one of the most common and practical diagnostic and treatment methods in traditional Chinese medicine. It is not only simple and easy to implement, but also objectively and accurately reflects the condition, providing important basis for understanding the development and changes of diseases.
Tongue diagnosis is also an important component of the “four diagnostic methods” in traditional Chinese medicine. Doctors can use tongue diagnosis to diagnose symptoms and apply medication. If ordinary people can also master tongue observation, which is the most intuitive technique to show our physical health status, it will undoubtedly help prevent diseases and improve health levels.
Daily health can be regulated through traditional Chinese medicine!
Traditional Chinese medicine has a history of thousands of years, and its treatment methods are rich and diverse. The core treatment methods include eight methods: sweating, vomiting, descending, harmonizing, warming, clearing, dissipating, and tonifying.
As stated in “Medical Mind Enlightenment”: “When it comes to the reliance on diseases, the eight characters of cold, heat, deficiency, excess, exterior, interior, yin, and yang are used to unify them. When it comes to the prescription of diseases, the eight methods of sweating, vomiting, descending, harmonizing, warming, clearing, eliminating, and supplementing are used to complete them.”
It may also be known from the daily life of health preservation, treatment and recuperation that the methods of Chinese medicine recuperate the body mainly include acupuncture and moxibustion therapy, scraping therapy, massage therapy, Chinese medicine therapy, etc.
With a clear understanding of physical fitness and health status, targeted combination of one or more appropriate conditioning methods can maximize the therapeutic effect and efficiently and accurately regulate a healthy and comfortable living state.

The Development History of Automation

in 946, D., a mechanical engineer at Ford Motor Company in the United States S. Harde first proposed the term “automation” and used it to describe the process of automatic transmission and machining of engine cylinders. In the 1950s, the development of automatic regulators and classical control theory led automation into a local automation stage dominated by single variable automatic regulation systems. In the 1960s, with the emergence of modern control theory and the promotion and application of electronic computers, automatic control and information processing were combined, bringing automation into the comprehensive automation stage of optimal control and management in the production process.
In the 1970s, the object of automation became large-scale, complex engineering and non engineering systems, involving many problems that were difficult to solve with modern control theory. The study of these issues has promoted innovation in the theory, methods, and means of automation, leading to the emergence of large-scale system control and intelligent control of complex systems. Advanced automation systems that comprehensively utilize achievements in computer, communication technology, system engineering, and artificial intelligence have emerged, such as flexible manufacturing systems, office automation, intelligent robots, expert systems, decision support systems, computer integrated manufacturing systems, etc.
The emergence and application of automatic devices dates back to the 18th century. The formation period of automation technology was from the late 18th century to the 1930s. In 1788, British mechanic J. Watt invented the centrifugal governor (also known as the flyball governor) and connected it to the valve of the steam engine to form a closed-loop automatic control system for the speed of the steam engine. Watt’s invention opened a new era in the application of modern automatic control devices and had a significant impact on the development of the first industrial revolution and later control theory. People have started to use automatic adjustment devices to address control issues raised in industrial production. These regulators are devices that track given values, keeping some physical quantities near the given values. The application of automatic regulators marks a new historical period for automation technology. After entering the 20th century, various automatic regulating devices were widely used in industrial production, promoting the analysis and comprehensive research of regulating systems. Although feedback control structures were widely used in automatic regulators during this period, theoretical research on the principles of feedback control began in the 1920s. In 1833, British mathematician C. Babbage first proposed the principle of program control when designing analytical machines. In 1939, the world’s first group of professional research institutions on systems and control were established, which made theoretical and organizational preparations for the formation of classical control theory and the development of local automation in the 1940s.


The 1940s to 1950s were the period of local automation, and the classic control theory formed during the Second World War played an important role in promoting the development of local automation after the war. In the process of solving the problem, classical control theory was formed, and various precision automatic adjustment devices were designed, opening up a new scientific field of systems and control. This new discipline was called servo mechanism theory in the United States at the time and automatic adjustment theory in the Soviet Union, mainly aimed at solving single variable control problems. The name classical control theory was proposed at the first United States Joint Conference on Automatic Control in 1960. After 1945, due to the lifting of the wartime publishing ban, there were works that systematically expounded classical control theory. In 1945, American mathematician Wiener N. extended the concept of feedback to all control systems. After the 1950s, there were many new developments in classical control theory.. The methods of classical control theory can basically meet the needs of military technology during World War II and the needs of post-war industrial development. But by the late 1950s, it was discovered that applying the methods of classical control theory to multivariable systems would lead to incorrect conclusions. The methods of classical control theory have their limitations.
The invention of electronic digital computers in the mid-1940s ushered in a new era of digital program control. Although it was still limited to automatic computing at that time, the successful manufacturing of ENIAC and EDVAC opened up a new era of electronic digital program control. The invention of electronic digital computers laid the foundation for the widespread application of program control and logic control in control systems in the 1960s and 1970s, as well as the widespread use of electronic digital computers to directly control production processes.
Since the late 1950s, it has been a period of comprehensive automation, during which space technology has developed rapidly and there is an urgent need to solve the optimal control problem of multivariable systems. So modern control theory was born. The formation and development of modern control theory have laid the theoretical foundation for comprehensive automation. At the same time, microelectronics technology has made new breakthroughs. Transistor computers emerged in 1958, integrated circuit computers emerged in 1965, and single-chip microprocessors emerged in 1971. The emergence of microprocessors has had a significant impact on control technology, and control engineers can easily use microprocessors to achieve various complex controls, making comprehensive automation a reality. “Automation” is an American D S. Harder proposed in 1936 that in a production process, the transfer of parts between machines does not require human handling, which is called “automation”.
On February 25, 2022, Hunan Huada Dana Intelligent Manufacturing Technology Co., Ltd. produced the first integrated automated nucleic acid testing laboratory in the province, which was launched in the eastern industrial park of Yiyang High tech Zone.
