Analysis of Development Strategy of Modern Instrumentation Technology

At present, China is experiencing an important historical stage of changing the industrial structure through technological innovation and upgrading the national economy from all aspects. Measuring with instruments is a means for people to obtain information from nature. At present, the vast majority of China's advanced instrumentation rely on imports, but the most advanced foreign instruments and instruments are generally developed in the laboratory, the market can not buy. The scientific and technological innovation activities that China must carry out in the first place cannot rely solely on imported commodity instruments and meters. It is necessary to carry out the development of the most advanced instrument and meter activities from now on. After years of hard work, we will provide our country's scientific and technical personnel with the most advanced domestic instruments and meters.

Instrumentation technology covers sensing technology, measuring instruments, measuring instruments, analytical instruments, automation instruments, etc., and is widely used in various fields such as national defense, industry, people's livelihood, and medical care. It can be considered that instruments and meters are the basic means and important equipment for information measurement and control in the physical world. They play a decisive role in the process of the modernization and industrialization of society in today’s society. They are the “predecessors” of scientific research and industrial production. "Multiplier", the "combat power" of military guarantees, and "materialized judges" in national activities. Technological innovation, method first, instrumentation are tools. Academician Qian Xuesen of China’s leading scientist pointed out: “Information technology includes measurement technology, computer technology, and communication technology. Measurement technology collects and processes information, and it is the source of information technology and the key to this.” Scientist of the discovery of the elemental cycle law Russian scientist Mendeleev said: "Measurement is the foundation of science."

With the development of national economy and high-tech industries, modern instrumentation technology has become China's strategic needs, especially China's deep space exploration, deep sea and deep earth exploration, manned spaceflight, large aircraft, aircraft carrier, nuclear power, high-speed railway, large-scale petrochemical As well as the development of national major projects such as medical and health care, and the development of national economy and people's livelihood, more urgent requirements are placed on the development of modern instrumentation technology.

Aiming at the development goals of China in 2030, the major and key common technologies of modern instrumentation are as follows.

1. Quantum measurement standards and traceability

Measurement standards are the basis for ensuring the accuracy of various measurement data, and have a fundamental role for all sectors of the national economy. Therefore, all countries attach great importance to the measurement standards.

The measurement standards must continue to develop and innovate with national scientific and technological innovation, economic construction, and social development, and form an advanced technological reserve, so as to effectively support China’s scientific and technological innovation, advanced manufacturing, and international trade competition, so as to ensure the nation’s measurement capabilities and our country’s Only by adapting the status of major economic power can we ensure the security of national defense and public safety at the source, ensure the fairness and reasonableness of trade settlement, and ensure the accuracy and reliability of measurement in public health, environmental monitoring, and resource protection.

Since the second half of the last century, research on quantum measurement standards has been carried out internationally. Quantum metrology standards use the latest achievements in quantum physics (mostly a breakthrough achievement won the Nobel Prize in physics) to establish a measurement that is thousands of times more accurate than the classical metrology standards that have been used for centuries. Developed countries have invested a lot of manpower and material resources to seize the commanding heights, and developing countries that do not establish quantum measurement standards lose their right to speak. Focusing on quantum measurement standards is a strategic measure in China. The most basic state-level quantum measurement standards should be established as soon as possible to serve major projects in all aspects of the country.

2. Precision Measurement Technology and Instrumentation in High-end Manufacturing Industry

Precision measurement technology and instrumentation are one of the three major supporting technologies for modern manufacturing, and are the core foundation and key technology in manufacturing technology and equipment manufacturing technology. They are also one of the main signs of national technology and industrial competitiveness. In the process of manufacturing "engineering strategic goals, precision measurement technology and instrumentation have unique urgency, importance, and particularity.

China's precision measurement technology should combine the application background of major manufacturing industries in China and major national engineering projects, such as high-end CNC machining centers, microelectronics manufacturing equipment (lithography equipment), large aircrafts, high-speed rail transportation equipment, large-scale energy electromechanical equipment, etc. , Organize and implement a number of major science and technology special projects for precision measurement technology, and focus on breakthroughs in a number of major common key technologies to lay the foundation for the system to improve the level of China's precision measurement technology and form a high-performance instrumentation industry with independent intellectual property rights.

3, life medical and food hygiene equipment

In the last ten years, under the influence of the globalized market mechanism, China has established a joint venture with foreign companies, absorbed foreign advanced technologies and implemented localization, independent innovation, and continuous technology accumulation. It has the scientific and technological strength to support medium and low-end medical instruments. In some areas also has a considerable share (such as electronic blood pressure monitors, monitoring modules, ultrasonic detectors, etc.). However, in the field of high-end medical instruments (such as CT, MRI, and PET), we basically do not have original technologies nor advanced production and process technologies, and we should vigorously carry out key research.

In the past ten years, the country has continuously given strong support to key food safety technologies, developed various types of detection methods and testing technologies in the field of food safety, improved many previously overlooked food safety issues, and also proposed the Food Safety Law. With the implementation provides protection. Scientific instruments and testing techniques are technical support for ensuring food safety, but nowadays, most of the large-scale scientific instruments (mainly analytical instruments) needed in food safety detection technologies rely on imports, and only some small and medium-sized instruments can be made domestically. .

4, deep space exploration equipment

Deep space exploration instrument is the core of deep space exploration. Deep space exploration is an important way to realize human exploration of knowledge and understanding of the universe. It has become the most active strategic frontier technology in the field of space technology. Through constant exploration of unknown areas, it will promote cross-cutting and theoretical breakthroughs in many basic disciplines, and will ensure national security through technological advancement. At the same time, it will create new technology markets related to it, and comprehensively upgrade the country’s overall national strength from the aspects of economy and science and technology. The earth improves our country’s international status. The detection technology, detection methods, experimental methods and new concepts developed through deep-space exploration activities are forward-looking technologies, and are the major driving forces for continuous innovation and development in many technology fields, and will greatly promote China’s independent interplanetary detection capabilities and space resources. Utilizing the enhancement of capabilities and spatial weather forecasting capabilities to better understand the Earth and serve the earth and promote national security and national economic development.

Gradually establish a more complete deep space exploration scientific research system, deep space exploration instrument technology development system and engineering development system, focusing on the moon and Mars to carry out long-term sustainable deep space exploration and manned deep space exploration missions.
