Instruments can improve, extend, or complement a person's faculties. People use sense organs to see, hear, taste and touch external things, and instruments such as microscope, telescope, sound level meter, acidity meter, pyrometer, vacuum centrifuge concentrator can improve and expand these functions of people; In addition, some instruments and meters, such as magnetometers and ray counters, can feel and measure physical quantities that can not be felt by human sensory organs, and some instruments and meters can exceed the ability of people to record, calculate and count, such as high-speed cameras and computers.
Instrument is an important "tool" for the development of science and technology. The famous scientist Mr. Wang Daheng pointed out that "the machine is the tool to transform the world, the instrument is the tool to understand the world". Instrument is the "multiplier" of industrial production, the "pioneer" of scientific research, the "combat effectiveness" of military affairs, and the "materialized judge" of modern social activities. Self-evident, the instrument in today's era to promote the development of science and technology and national economy has a very important position.
1. Instruments are an important prerequisite and fundamental guarantee for the development of science and technology. Any great leap in the history of human development is driven by huge innovation and fundamental change based on tools. The development and innovation of scientific instruments as "tools" are often important elements for the birth of scientific and technological innovation.
2. Instruments are an important guarantee for economic development and national defense security. Instruments are an indispensable basic condition for ensuring economic development and national security. First of all, the famous scientist Mr. Qian Xuesen pointed out: "The key technology of the new technological revolution is information technology. Information technology is composed of measurement technology, computer technology and communication technology. Measurement technology is the key and foundation."
3, instrument is an important force to promote the construction of a harmonious society. Global problems such as resource depletion and environmental pollution have become the bottleneck of social health development. Food safety problems, public emergencies, disease diagnosis, flammable and explosive chemical dangerous goods to people's lives have brought serious impact, the solution of these major problems are inseparable from the advanced detection technology and means.
4. Digital and intelligent
5. Because of the improvement of microelectronic skills, instrumentation products are further blended with micro disposers and PC skills, and the digital and intelligent degree of instrumentation is improved from time to time. Taking the "DSPS" concept proposed by Texas Instruments Company of the United States as an example, it takes the DSP chip as the center, and jointly advances the front part of the mixed signal circuit, ASIC circuit, components and development of things to supply the whole system processing scheme. Instruments used a lot of very large planning integration (VLSI) of new devices, surface mount technology (SMT), multi-layer circuit board printing, wafer planning integration (WSI) and multi-chip module (MCM) and other new technology, CAD, CAM, CAPP, CAT and other computer aided tricks. So that multimedia skills, human-computer interaction, trance temperance, artificial neuron collection and other new skills in modern instrumentation have been widely used.
6. Collect
7. A variety of intelligent instruments and meters have been facing the market one after another, and instruments and meters are undergoing in-depth intelligent innovation. The integrated test system is also collecting, and each instrument is connected by GPIB bus and VXI bus.
8. Miniaturization
9. MEMS products include automotive accelerometers, pressure, chemical, flow transmitters, microspectrometers and other products, widely used in the field of science, aerospace, biomedical, automotive industry, military, industrial control and other fields.
