Speaking of the basic overview of China's instrumentation and measurement control industry, let us know some statistics. In 2007, the number of enterprises above designated size in China's instrumentation industry was 3,954, with a total output value of 307.8 billion yuan and sales revenue of 30 billion yuan, both of which exceeded 300 billion yuan. In the year of 2004, 100 billion yuan, 200 billion yuan in 2006, and annual sales growth of more than 30%. 300 billion yuan in four years, exports reached 8.8 billion US dollars, an increase of 36% over the previous year. Currently, China's instruments The instrumentation and measurement control industry has formed an industrial system with relatively complete categories, reasonable layout, and considerable technical basis and production scale. In Asia, China is the second largest instrument and meter producing country except Japan, which is the strongest comprehensive strength of developing countries. Instrumentation producing country. From the technical level analysis of products, most domestic instruments and meters are still in the developed countries in the mid-to-late 1990s. The middle and low-end products are basically complete in variety, capable of scale production, and the quality is basically stable. It can meet the requirements of the domestic market and has a batch export. For example, electrical instrumentation has a market share of 95% in the domestic market, and 13% of its products are exported. Shenzhen produces 7 million digital multimeters every year and sells to more than 90 countries around the world. Domestic instruments and meters, there are also a few high-end products close to the international technical level. Among the national key scientific and technological projects, the aerospace industry and the national defense security field, which must be independently innovated and developed, have made new breakthroughs in some instrumentation technologies. The eight kinds of detection instruments carried by China's Chang'e-1 satellite are independently developed and designed by Chinese scientists and technicians. They not only have reached the international advanced level in technology, but also have their own characteristics and innovations. In terms of engineering application technology, it has been able to undertake a complete set of major national engineering instrumentation systems. The major progress in China's instrumentation and measurement control will be discussed later, and it will not be enumerated here. According to the application field, we are used to divide instrumentation and measurement control into six categories, namely industrial automation instrumentation and control systems, scientific instruments, medical instruments, electronic and electrical measuring instruments, various special instruments, sensors and instruments. Instrument components and functional materials. This is a rough classification with many intersections and infiltrations. Industrial automation instrumentation and control system, mainly used in the detection and control of industrial production processes; scientific instruments are widely used, including scientific research, teaching experiments, material analysis, safety monitoring, etc.; medical instruments are applied to life science research And clinical diagnosis and treatment; electronic and electrical measuring instruments are used to measure various electronic and electrical parameters; various special instruments are used in various specialized fields, such as agriculture, environmental protection, meteorology, hydrology, geology, ocean, etc. In addition to the extraordinary requirements of the application field, the basic principles and application methods of the instrument are not fundamentally different from other instruments such as scientific instruments; sensors, components and functional materials are mainly used for signal acquisition, instrument production and Use the material. Sensors have become a key factor affecting the development and application of instrumentation and measurement control. The basic theory and technology of various instruments constitute the basic content of the instrumentation and measurement control discipline system. Their industry has become an important component of the instrumentation and measurement control industry system, and their development determines the future of instrumentation and measurement control. . When we analyze the status quo of China's instrumentation and measurement control, we must not be soberly familiar with it compared with the international advanced level, compared with the actual needs of China's economic and social development, there is still a big gap. The gap is all-round, and the most important ones are three: First, China's instrumentation industry is small in scale and low in output value. Enterprises are also small in scale and low in output value. In 2007, the total output value of China's instrumentation industry was 300 billion yuan, accounting for only 2.5% of the total industrial output value. Ten years ago, the total output value of the US instrumentation industry reached US$400 billion, accounting for 4% of the total industrial output value. Currently, the US instrumentation The annual output value of the enterprise exceeds 2 billion US dollars and not less than 50. The largest instrument and meter enterprise in China, the annual output value of Jingyi Group is 8 billion yuan, and the Sichuan Instrument Group is 6 billion yuan. Compared with the two, the gap is too big. The scale and output value of industries and enterprises directly affect the vitality and development of the industry. To narrow and eliminate this gap, we need to work hard for 10 years and 20 years. Second, there are still many problems in the quality and variety of instrumentation products in China. The reliability and stability of the product have not been fundamentally solved for a long time, which seriously affects the market sales and normal use. Many large precision instruments are still not produced, and domestic demand is almost entirely imported. In 2007, China’s exports of instrumentation products reached US$8.8 billion, but imports reached US$17.2 billion and the deficit was US$8.4 billion, making it the largest in the equipment manufacturing industry. This problem is not solved. The development of China's instrumentation and measurement control disciplines and industries will not be able to get rid of the backward and passive situation. Third, China's instrumentation industry's ability to innovate is not strong, and it is unable to assume the responsibility of the main body of technological innovation. International instrumentation technology innovation is developing very fast, and the cycle of product renewal is only about 2 to 4 years. Most of the sales of most companies are almost from new products listed in 5 years. Many of China's instrumentation products are also based on the introduction of technology in the 1980s. A considerable number of enterprise products are consistently developed for 10 years, relying on eating old people for a living. The reasons for the lack of independent innovation capability are many, and the most influential ones are nothing more than two: First, there are too few funds for scientific and technological innovation and development. The investment of foreign enterprises for scientific and technological innovation is generally 8 to 10% of sales revenue, while the investment of Chinese enterprises rarely exceeds 3 to 5%. Moreover, the sales revenue is not much, which greatly limits the effective development of scientific and technological innovation; Human factors, some leaders do not attach importance to independent innovation, and more are lack of innovative talents. The 17th National Congress of the Communist Party of China proposed that improving the capacity for independent innovation and building an innovative country are the core of the national development strategy and the key to improving overall national strength. It has become an urgent historical mission for enterprises to enhance their technological innovation capabilities. Third, the trend characteristics Today, the trend of instrumentation and measurement control development is: facing the stability, reliability and adaptability requirements of products; the technical indicators and functions are continuously improved; the new scientific research results are adopted first; the high-tech is widely used; And the measurement and control unit is becoming more and more miniaturized and intelligent; the instrument and the measurement and control unit can be used independently, embedded and networked; the scope of instrument measurement and control is expanded to three-dimensional and globalized; the measurement and control function is developed to be systematic and networked; Hand-held and even personalized instruments have been developed in large numbers. The technical features are: comprehensively synthesize various new technologies, and innovate and develop new weak signal sensitivity, sensing, detection and fusion technologies based on the research of instrument-related types of sensors, components and materials and technologies, material atomic and molecular level detection. Technology, complex analysis of combined sample technology, life science in situ, in situ, real-time, online, high sensitivity, high-throughput, high-selective detection technology, create a variety of new types of testing instruments; combined with system theory, control On the basis of the development of industrial automation measurement and control online analysis and control, in-situ analysis and control, high reliability, high performance and high adaptability, innovative development of industrial automation instrumentation and control systems; combined with life sciences, The development of human science, the development of medical diagnosis and treatment of health monitoring, early diagnosis and treatment, non-destructive diagnosis, non-invasive and low-invasive direct diagnosis and treatment, precise positioning of treatment technology based on the development of medical instruments; while tracking new subject areas and various application areas Develop and develop a variety of dedicated, fast, automated inspection and measurement technologies and special instruments Instruments. Industrial automation instrumentation and control systems and scientific instruments occupy half of the total instrumentation and measurement control in both production value and market, and are the two pillars of instrumentation and measurement control systems. Due to the limited time available for the speech, let us focus on the future development of these two types of instruments.
