Editor's note: Modern instrumentation is a major feature of high technology. With the rapid development of science and technology and the continuous improvement of automation, China's instrumentation industry will also undergo new changes and gain new development. We need to pay attention to the development of instrumentation.
High-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrument industry. It is also the mainstream of instrumentation and its development in the new century. The further expansion of the application field, especially the non-traditional application field, has injected new vitality and new impetus into the sustainable development of the instrumentation industry.
The development of modern instrumentation plays a vital role in the development of industry. We need to pay attention to the development of instrumentation. Driven by modern science and technology and productivity, the instrument originally used as a measuring instrument has developed into a relatively complete discipline and plays an increasingly important role in today's national economy and technological development.
China's instrumentation industry will undergo a new major turning point
With the rapid development of science and technology and the continuous improvement of automation, China's instrumentation industry will also undergo new changes and gain new development. High-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrument industry. It is also the mainstream of instrumentation and its development in the new century.
With the advent of fieldbus, the development of process measurement and control instrument has experienced a major turning point and a rare opportunity. Fieldbus has become a hotspot of global automation technology. Fieldbus is an open, all-digital, two-way, multi-station communication system between on-site intelligent instrumentation and control room. Its production is not only the actual demand of the majority of users and the result of technical competition among manufacturers, but also the product and product upgrade of computer technology, communication technology and control technology in the field of industrial control, and to achieve further high precision and high performance. (especially multi-parameter online real-time measurement and control and automatic measurement and control), high stability, high reliability, high adaptability, multi-function, low consumption, etc. provide great power and development space.
The further expansion of the application field, especially the non-traditional application field, has injected new vitality and new impetus into the sustainable development of the instrumentation industry.
The overall development trend of instrumentation products is “six highs and one long†and “twentyâ€. Throughout history, analyzing the status quo and looking into the future, we can make the following conclusions: In the future, traditional instruments and meters will still be oriented toward high performance, high precision, high sensitivity, high stability, high reliability, high environmental protection and long life. The direction of the "long" development.
International Instrumentation Trends
The development of international instrumentation is extremely rapid. The main trends in the development of international instrumentation in the past 10 years are:
The emergence of digital technology has increased the accuracy, resolution and measurement speed of analog instruments by several orders of magnitude, laying a good foundation for test automation. The introduction of the computer has caused a qualitative change in the function of the instrument, from the measurement of the individual parameters to the measurement of the characteristic parameters of the entire system, from simple acceptance, display to control, analysis, processing, calculation and display output, from a single The instrument is converted to a measurement using a measurement system. The further penetration of computer technology in instrumentation has led to the emergence of data domain testing in addition to the traditional time domain and frequency domain. In the 1990s, the breakthrough in instrumentation and measurement science and technology was the improvement of instrumentation intelligence; the large number of DSP chips came out, which greatly enhanced the digital signal processing function of instrumentation; the development of microcomputers made instrumentation have stronger data. Processing power and image processing functions; fieldbus technology is a network communication technology developed rapidly in the 1990s for various field automation devices and their control systems. Internet and Internet technologies will also enter the control field. Modern instrumentation products will develop in the direction of computerization, networking, intelligence and multi-functionality. Interdisciplinary comprehensive design and sophisticated manufacturing technology enable it to acquire higher speed, more sensitive, more reliable and simpler. Comprehensive information that is analyzed, detected, and controlled.
In the next 10 years, a higher degree of intelligence should include a series of functions such as understanding, reasoning, judgment and analysis. It is the result of a combination of numerical, logical and knowledge analysis. The symbol of intelligence is the expression and application of knowledge. Using new effects of physics and high-tech and its achievements to develop new sensor technology and test instruments with high sensitivity, high stability and strong anti-interference ability. Such as: the use of high temperature superconducting quantum interferometer (SGUID) to develop measurement and testing equipment, physical testing equipment, geography and geology instruments, chemical analysis equipment, medical equipment, non-destructive materials testing equipment. The use of ellipsometry to detect optical fibers, optical glass, etc., combined with near-field optics, can not only measure the fine structure of the surface, but also distinguish the material of the measured object according to the near-field optical reflection polarization information. This is the new experimental research. explore. Using tunable frequency-stabilized laser spectrometer technology for high-precision geometry and mechanical quantities and a variety of non-morphometric measurements, a new generation of miniature fiber-optic guided laser interferometers can be developed that can range from nanometers to a few meters or more. Large range, resolution up to 10mm.
