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.

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.
Images from the internet
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.
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.

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.

On March 6, 2013, ABB announced its business performance in China for 2012, with stable growth in sales revenue exceeding 5.2 billion US dollars. This performance was mainly due to the increase in market demand for improving domestic manufacturing and infrastructure construction, as well as the sustained growth of ABB’s export business.

Application of automated robotic arms and automated production lines in various industries of the national economy

1. Diversification of raw materials
The first major category is the mechanical manufacturing industry, which includes the processing of durable consumer goods such as clocks, sewing machines, bicycles, and household appliances using metal materials as raw materials. The second category is based on non-metallic materials such as agriculture, forestry, animal husbandry, sidelines, and chemical products as raw materials for processing. For example, pastry machinery in food machinery mainly uses agricultural products as raw materials; Canning and brewing machinery mainly use agricultural and sideline products as processing materials; Pulp and paper machinery uses forest products and agricultural by-products as raw materials; Leather machinery mainly uses livestock products as raw materials; Ceramics, glass, and plastic machinery use minerals and chemical products as their raw materials. It indicates that automated robotic arms and automated production lines are widely used in various fields.
2. Diverse types of automated robotic arms and automated production line processes;
(1) Metal cutting and assembly are used to complete mechanical functions.
(2) Tobacco is the one that completes physical functions.
(3) Fermentation is the process that completes biochemical reactions.
(4) Electroplating and corrosion are the processes that complete electrochemical reactions.
(5) The processes that complete chemical reactions include cooking in papermaking machinery and melting in light bulb machinery.
3. Diverse categories and diverse structures
There are many industrial categories, and the machinery used varies greatly in terms of principles and motion mechanisms due to different industries, processed products, functions, and functions. Even those that perform the same function may have different working principles and mechanisms. If different equipment can be used to process the same product on a mechanical processing production line, the automated robotic arm applied to it may also differ from the automated production line; Candy packaging machines have various different process principles and structures; The light bulb winding machine can be divided into non core, continuous with core, and discontinuous with core winding machines due to different process principles.
4. Large product volume and high degree of automation
Industrial products are essential for people’s daily lives, and therefore require mass production, which inevitably requires the widespread use of semi-automatic and automated robotic arms. As a result, the application of automated production lines is becoming increasingly widespread.
5. Industrial automation robotic arms often have characteristics such as complex movements, high mechanism movement speed, wide range of disciplines, and fast updates.

The development direction of folding and editing this paragraph
With the rapid development of China’s national economy and industry, the variety, scale, design and manufacturing technology of industrial automation robots have also been rapidly developed and improved. It has become an inevitable trend to independently design and manufacture from single machines to complete sets of equipment and even automatic production lines.
With the development of new materials, processes, and technologies, various automated robotic arms are rapidly advancing towards mechatronics and intelligence.
Mechatronics integration is the result of various technologies permeating each other, and its main related technologies can be summarized into six aspects: mechanical technology, detection and sensing technology, information processing technology, automatic control technology, servo transmission technology, and overall system technology.

Introduction to Electrical Automation

In 1908, Tang Wenzhi, the then president of the Shanghai Higher Industrial School (now Jiaotong University) under the Ministry of Posts and Communications, adjusted the departmental structure. We have successively added railway and electrical engineering majors with a three-year education system, marking the beginning of higher education in electrical engineering in China. This is the earliest electrical engineering major. With the development of electricity and the need for social division of labor, Jiaotong University changed its Electrical Engineering Department to Electrical Machinery Department in 1913. In 1917, the Electrical Machinery Department began to establish wireless switches. In 1928, it was changed to the School of Electrical Engineering, and in 1937, it was changed to a department, divided into “Power Gate” and “Telecommunications Gate”, namely “Strong Electric” and “Weak Electric”.
In 1912, Tongji Medical and Engineering School (now Tongji University) established the Department of Electrical Engineering, which has now developed into the Department of Electrical Engineering of the School of Electronic and Information Engineering at Tongji University; In 1920, the Public Industrial Specialized School (now Zhejiang University) established the Department of Electrical Engineering, which has now developed into the School of Electrical Engineering at Zhejiang University; In 1923, the Department of Electrical Engineering was established at Central University (now Southeast University); In 1932, Tsinghua University established the Department of Electrical Engineering, which has now developed into the Department of Electrical Engineering and Applied Electronic Technology; In 1933, the Department of Electrical Engineering was established at Beiyang University (now Tianjin University), which has now developed into the School of Electrical and Automation Engineering at Tianjin University.

In 1952, China underwent a large-scale departmental adjustment, leading to the emergence of a group of multidisciplinary universities with engineering as the main focus, as well as a group of mechanical and electrical colleges. These colleges basically established departments of electrical engineering or power engineering.
In 1977, after the restoration of the college entrance examination system, most universities gradually changed their “Department of Electrical Engineering” or “Department of Electric Power Engineering” to “Department of Electrical Engineering”. After the 1990s, it was gradually renamed as the School of Electrical Engineering.
In 1993, in the catalog of undergraduate majors in ordinary higher education institutions issued by the Ministry of Education, electrical related majors in the engineering category were divided into two branches: electrical engineering and electronics and information. Electrical engineering includes five majors: motor and electrical appliances and their control, power system and its automation, high voltage and insulation technology, industrial automation, and electrical technology.
In 1998, the Ministry of Education issued the “Catalogue of Undergraduate Majors in Ordinary Higher Education Institutions (1998)”, which merged electrical engineering and electronics and information into electrical information. The original 19 majors were merged into 7. Among them, the majors of motor and electrical appliances and their control, power system and its automation, high voltage and insulation technology, and electrical technology in the original electrical engineering category have been merged into the majors of electrical engineering and its automation.
In 2012, the Ministry of Education issued the “Catalogue of Undergraduate Majors in Ordinary Higher Education Institutions (2012)”, which merged the original Electrical Engineering and Automation major with the Electrical Engineering and Automation, Electrical Information Engineering, Power Engineering and Management, Electrical Technology Education, and Intelligent Electrical Machinery and Electrical Appliances special majors to form the Electrical Engineering and Automation major.

Omron: The i-Automation of Scholar Technical Experts! Evolutionary theory

In 2015, Omron innovatively proposed a new intelligent manufacturing concept, i-Automation!. As a result, this innovation storm instigated by Omron extends step by step from the “manufacturing site” and leverages the future of innovative automation. Specialization and innovation have become i-Automation! A solid footnote to success.
By 2020, we will be confronted with the COVID-19 that has swept the world. The increasing geopolitical friction will make the global economic atmosphere more tense. Under the superposition of various uncertainties, what made Omron achieve offensive growth in the first half of the year? I-Automation! What new chapters have been added to the theory of evolution?
On August 31, 2020, Omron Automation (China) Co., Ltd. President Hiroshi Ohashi and Gongkong ® President Pan Yingzhang practices the annual agreement between the two parties through cloud based dialogue and reveals the answers to the above puzzles.

According to the Nikkei Chinese website on August 20, the real gross domestic product (GDP) of 24 major countries in the world from April to June 2020 shrank by 9.1% year on year, and the impact of the COVID-19 epidemic is very prominent. These 24 countries account for two-thirds of the world’s GDP, with only China achieving positive growth.
Faced with this sudden stress test, Omron shifted from passive defense to active attack and defense. “According to our investigation, customers were greatly affected after the Spring Festival, and by mid March, their production activities had resumed by 50-70%,” said Da Chang Hezhi.
According to Da Chang Hezhi, Omron’s performance in the second quarter of this year was impressive: a 70% increase compared to the first quarter and a 20% increase compared to the same period last year.
He believes that there are three main reasons: firstly, in the first quarter, due to the impact of the epidemic, everyone was in a wait-and-see state, and project investment was temporarily postponed. After April, the investment direction became clearer; Secondly, medical supplies such as masks, artificial ventilators, and non-contact thermometers have become a “hard currency” in the market, and the demand for such equipment has surged. Omron has achieved considerable success in the essential goods market; Thirdly, after April, the suspended customer demand was rapidly released, and the demand for components increased rapidly. Omron had anticipated this trend and prepared inventory in advance, resulting in an improvement in IAB (Industrial Automation Business) performance.
“In summary, this epidemic means more opportunities for Omron,” said Da Chang Hezhi. For example, the market for essential goods such as medical supplies is an area that Omron (IAB) has not been involved in in the past; For example, more customers are cross-border producers of mask machines and urgently need Omron to provide them with supporting solutions and products.
How to respond quickly and seize opportunities is crucial. On the one hand, Omron timely learns about customer needs, disassembles them into corresponding supply products, prepares in advance, and actively responds; On the other hand, overseas markets such as the United States, Europe, and Japan have been affected by the epidemic and have stopped production, while Omron has already resumed work and production in China, and can actively and timely respond to the needs of overseas customers. At the same time, Omron also organized and analyzed the impact and changes of the epidemic on customer production sites and work itself, actively thinking about i-Automation! How to empower customers and turn challenges into more opportunities.
For the future development of the industrial automation market, Da Chang He Zhi still maintains an optimistic attitude. At present, Omron is optimistic about the secondary battery, food and beverage, semiconductor and other industry markets.
I-Automation! Diexin
Visualization is required at the manufacturing site
The methodologies for intelligent manufacturing in Japan and China are not the same. Da Chang Hezhi stated that “Made in China” promotes practical operations through concepts, anticipates the concepts of informatization, digitization, and intelligence, and then gradually implements them on manufacturing sites. “The Japanese manufacturing industry does not place too much emphasis on the concepts of informatization, digitization, and intelligence, but focuses on optimizing and improving every detail of the manufacturing site.”
From i-Automation! From the birth of concepts to the gradual implementation and upgrading of integrated (control evolution), intelligent (intelligence), and interactive (new human-machine cooperation) in manufacturing sites, Omron is more concerned with how to help customers solve practical problems, innovate manufacturing sites, and innovate the future of automation.

Building a modern factory has become a mainstream demand at present, but Da Chang He Zhi directly points to customers’ “misconceptions”. “Building a modern factory is not just about achieving informatization and intelligence. Omron believes that improving production efficiency and product quality on the manufacturing site, reducing energy consumption, and visualizing is the first step.”
At the upcoming 22nd China International Industrial Expo (CIIE), Omron will showcase intelligent unit production lines featuring human-machine collaboration. This production line integrates advanced technologies unique to Omron such as AI, IoT, MOMA ※, and collaborative robots. Based on big data analysis, it is actually applied in Omron’s own factory’s near future production management system.

By visualizing the management of homework and process status, Omron creates a self disciplined production site, reducing talent training time by half; Through traceability management, the defect outflow rate caused by manual operation errors is reduced to 0; By leveraging the advantages of both humans and robots and improving automation levels, production efficiency can be doubled.
