High voltage switch tester manufacturing base interprets the development trend of China's instrumentation industry

From the aspects of the interrelationships and common problems of the components of the coal quality science and technology disciplines and the overall situation of China's national economy, scientific research, national defense construction, and social development, it is recommended that scientific research directions in the disciplines include: new types of sensors and information acquisition technologies; Process control systems and measurement and control equipment and system integration technologies that are compatible with national key projects; measurement and control technologies and instrumentation in precision manufacturing; microanalysis instruments and key technologies; digital medical instruments and their key technologies; Measurement standard system.

1. New sensor and information acquisition and sensing technology

2. Sensing technology is not only the basis for detection, it is also the basis for control. This is not only because the control must be based on detecting the input information; it is the accuracy and state of hesitation control that must be perceived, otherwise the control of the control effect is still blind.

Information acquisition and sensing technology are the basic technologies of the discipline of instrument science and technology; new sensors are the basis for the development of high-level measurement and control instrumentation. Sensing technology has become a bottleneck restricting the development of measurement and control instrumentation.

The new sensors and information acquisition and sensing technologies are mainly used for the detection of useful information in the objective world. They include useful helium measurement sensitive technologies, working principles of various disciplines, remote sensing, remote control, new materials and other technologies, information fusion technologies, and sensor manufacturing technologies. Information fusion technologies such as sensor distribution, weak signal extraction (enhancement), sensor information fusion, imaging, and sensor manufacturing technologies involve microfabrication, biochips, and new processes.

3. Process control systems, monitoring and control equipment and system integration technologies that are compatible with national key projects

The high-tech instrument products of industrialized countries account for about 75% of the total varieties, but less than 20% in China. Industrial automation instrumentation and control system instrumentation domestic satisfaction rate, general engineering projects up to 80%, large-scale engineering projects less than 50%, mainly lack of intelligence and high precision, high reliability, large range, corrosion resistance, sealed , explosion-proof and other special requirements of automated instrument varieties.

The process control system and measurement and control equipment that are matched with national key projects mainly solve the intelligent metering and high-precision, high-reliability, large-range, corrosion-resistant, fully-sealed, explosion-proof, and other automated meter varieties with special requirements. Mainly includes various types of sensors and detection instruments that meet the on-site requirements, real-time process analysis instruments and on-line analysis technologies, new field control systems, e-network control systems, open control systems based on industrial control computers and programmable controls, and advanced control Technology, special measurement and control equipment and measurement and control technology, system integration technology, etc.

System integration technology directly affects the breadth and level of application of measurement and control instrumentation. It has a decisive influence on the degree of automation and benefits of large-scale projects, large-scale systems, and large-scale installations. It is a system-level information fusion control technology that does not include systems. Demand analysis and modeling technologies, physical layer device technologies, information communication conversion technologies in various parts of the system, and real-time technologies for application layer control strategies. In the case of operators operating groups for a variety of different positions, they should also include technologies for monitoring and intelligentizing tools, equipment, and systems in order to achieve the desired goals. These technologies are directly related to the effectiveness of measurement and control systems, and are based on information. The key to the development of technology to knowledge economy technology. Intelligent control technology can be said to be the most important and critical software resource in the measurement and control system.

From the current development trend, in the computer monitoring and control system after the enterprise information ERS/MES/PCS three-level festival, the price of the software has exceeded the hardware by three times. The price of advanced control software for automated measurement and control systems in the petrochemical, metallurgy, electric power, and pharmaceutical industries exceeds the system hardware price. Intelligent control technology includes human-like feature extraction technology, target automatic identification technology, knowledge self-learning technology, environment adaptive technology, and optimal decision-making technology.

4. Coal analysis instruments and key technologies in scientific analysis instruments

5. Analytical instruments are the most important and fastest-growing components of scientific instruments, and for analysis instruments contain the connotations of trace detection, miniaturization, high sensitivity, high resolution and high intelligence, which represent an important part of analytical instruments. The development trend and technical level have been applied more and more in life sciences, food safety, environmental protection, public safety (including anti-terrorism, anti-drug), clinical medicine, medical science and chemical engineering. The research directions of microanalysis instruments and their key technologies include:

(1) Research on the combination technology of different types of analytical instruments. When the content and structural analysis of trace and trace substances in complex matrices place extremely high demands on the resolving power of analytical objects, and when a single separation technology or even mass spectrometry separation technology can no longer separate useful information needed from complex information It is necessary to analyze the composition, structure, morphology, and even the overall morphology of the substances through the use of different combinations of analytical instruments to obtain information on atoms and molecules at the same time.

(2) Research on coal quality analysis instruments and key technologies used in process analysis and online analysis.

(3) Carry out research on the miniaturization of analytical instruments and related micro-root technologies, focusing on common and new technologies used in micro-analysis instruments, such as microfluidic technology, micro-processing technology, micro-detection technology, micro-light source, and all-electronics Research on spectroscopic systems, micro-spectrometers, new types of chips, etc.

(4) Develop high-sensitivity, high-resolution, high-performance micro-structured sensor research, and apply biochip technology, new chemical sensor technology, and multi-component (multi-parameter) integrated sensor technology to the research and development of analytical instruments.
