Instruments can enhance, extend, or complement a person's abilities. People use their senses to see, hear, taste and touch external things, and microscopes, telescopes, sound level meters, acidity meters, pyrometers, vacuum centrifuges, concentrators and other instruments can improve and expand these functions. In addition, some instruments, such as magnetometers, ray counters, etc., can sense and measure physical quantities that cannot be sensed by human sensory organs, and some instruments can surpass people's recording, calculation and counting capabilities, such as high-speed cameras, computers, etc.

Instrument is an important "tool" for the development of science and technology. Mr. Wang Daheng, a famous scientist, pointed out: "The machine is a tool to transform the world, and the instrument is a tool to understand the world." Instrument is the "multiplier" of industrial production, the "forerunner" of scientific research, the "combat effectiveness" of military, and the "materialized judge" of modern social activities. It goes without saying that instruments play a very important role in promoting the development of science and technology and the national economy in today's era.
1. Instrument is an important prerequisite and fundamental guarantee for the development of science and technology. Every great leap forward in human history has been driven by huge innovations and fundamental changes based on tools. As a "tool", the development and innovation of scientific instruments is often an important factor in the birth of scientific and technological innovation.
2. Instruments are an important guarantee for economic development and national defence security. Instruments are essential for ensuring economic development and national security. First of all, the famous scientist Qian Xuesen pointed out: "The key technology of the new technological revolution is information technology." Information technology consists of measurement technology, computer technology and communication technology. Measurement technology is key and fundamental to this."
3, tools are an important force to promote the construction of a harmonious society. Global problems such as resource depletion and environmental pollution have become bottlenecks restricting the development of social health. Food safety problems, public emergencies, disease diagnosis, flammable and explosive chemical dangerous goods have brought serious impact on people's lives, and the solution of these major problems cannot be separated from advanced detection technology and means.
4. Digital and intelligent
5. Due to the improvement of microelectronics skills, instrument products are further integrated with microprocessor and PC skills, and the degree of digitalization and intelligence of instruments is also constantly improving. Taking the "DSP "concept proposed by Texas Instruments as an example, the DSP chip as the center, jointly proposed the front-end part of the mixed-signal circuit, ASIC circuit, components and the development of the Internet of things, to provide the whole system processing scheme. The instrument uses a large number of new devices of VLSI, surface mount technology (SMT), multi-layer circuit board printing, wafer planning integration (WSI) and multi-chip module (MCM) and other new technologies, CAD, CAM, CAPP, CAT and other computer-aided techniques. Multimedia skills, human-computer interaction, trance control, artificial neuron acquisition and other new skills have been widely used in modern instruments.
Step 6 Collect
7. A variety of intelligent instruments have been facing the market, and instruments are undergoing in-depth intelligent innovation. The integrated test system also has the acquisition function, and the instruments are connected by GPIB bus and VXI bus.
8. Go small
9. MEMS products include automotive accelerometers, pressure, chemistry, flow transmitters, micro spectrometers and other products, which are widely used in the field of science, aerospace, biomedical, automotive industry, military, industrial control and other fields.
