The high-tech instrumentation products will become the mainstream of instrumentation technology and industry development in the past 20 years. Microelectronics technology, computer technology, precision machinery technology, high sealing technology, special processing technology, integration technology, thin film technology High-tech technologies such as network technology, nanotechnology, laser technology, superconducting technology, and biotechnology have developed rapidly. This background and situation constantly put forward higher, newer and more requirements for instrumentation, such as faster speed, higher sensitivity, better stability, less sample volume, minimal or no loss detection, and remote sensing. Telemetry and remote control are more remote, more convenient to use, cheaper, and less polluting. They also provide a powerful driving force for the development of instrumentation technology and industry, and become the material, knowledge and technical basis for the further development of instrumentation. In particular, it should be pointed out that in the past ten years, due to the research results of nano-scale precision machinery, the results of modern chemical research at the molecular level, the results of biological research at the genetic level, the research results of new sensor technologies and intelligent technologies, and the high-precision super A large number of contemporary and latest scientific and technological achievements, including the research results of performance special functional materials and the promotion and application of global network technology, have brought about fundamental changes in the field of instrumentation. These new achievements have not only become modern instrumentation and The soil, foundation, support and power that its industry relies on for survival and development, and it is rapidly changing the working principle and essential characteristics of instrumentation, and it has many and new products that can not be achieved and realized by traditional instruments. , super high functionality. It can be said that modern instrumentation products have become the most typical high-tech products. At present, it has not only completely broken through the traditional framework of light, machine and electricity, but has developed rapidly in the direction of computerization, networking, intelligence and multi-functionality, and due to the extensive use of high-tech science and technology research results, interdisciplinary Comprehensive design, sophisticated manufacturing technology and rigorous scientific application make it a step forward in the direction of higher speed, more sensitive, more reliable and simpler access to all-round information analyzed, detected and controlled. . It can be seen from the above analysis that high-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrument industry, and also the mainstream of instrumentation and its industry 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.
At present, fieldbus has become a hot spot in global automation technology. Fieldbus is a development, 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 combination of computer technology, communication technology and control technology in the field of industrial control. The emergence of fieldbus, for the upgrading of instrumentation, product upgrades, and to achieve further high precision, 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 and so on provide tremendous power and room for development.
The further expansion of the application field, especially the non-traditional application field, has injected new vitality and new power into the continuous development of the instrumentation industry. Looking back at the development process of the instrumentation industry, it can be clearly seen that the application range of instrumentation has been Covering all areas of human activities, and from traditional chemical composition analysis, physical quantity detection, mechanical measurement, astronomical geography, automatic control of industrial production processes, product quality measurement and control, and other traditional applications, further to biomedicine, bioengineering, Non-traditional applications such as the ecological environment have expanded. At the same time, with the development of high-tech and industry in polymer chemistry, molecular biology, life science, clinical medicine, pharmacy, materials, environmental monitoring and control in the new century, the application field of instrumentation will be expanded more rapidly. For example, at the International Conference on Chemistry and Applied Spectroscopy held in Pittsburgh last year, the concept of "comprehensive morphological analysis" of human body was put forward, and it is hoped that the development and development of "human" components and their chemical composition images can be "directly". Instrumentation system. It can be said that the advancement of modern science and technology has made the application field of instrumentation more and more extensive and deeper. All of this will undoubtedly provide another powerful driving force for the further development of instrumentation and show a bright future.
