Introduction: the instrument and meter industry is a key industry in the field of automation. In the past few years, with the continuous development of China's automation application environment, the appearance of the instrument and meter industry has changed with each passing day, and many enterprises in this field have also developed rapidly. At present, the instrument and meter industry is facing a new period of development. The 12th five-year plan for this industry also puts forward some key technologies for key development according to the requirements of the new period, this undoubtedly has important guiding significance for the future development of the industry. According to the 'Twelfth Five-year development plan for the instrument and meter industry' published on the Internet, China instrument network has compiled key content. The plan shows that by 2015, the total output value of the industry will reach or approach a trillion yuan, with an average annual growth rate of about 15; Exports exceeded 30 billion US dollars, of which the export value of domestic enterprises accounted for more than, and the trade deficit began to decline at the end of the 12th Five-Year Plan or the beginning of the 13th Five-Year Plan; Actively cultivate the three industrial agglomeration areas of Yangtze River Delta, Chongqing and Bohai Rim to form 3- Five enterprises with sales exceeding 1 billion yuan are over. During the 12th Five-Year Plan period, China's instrumentation industry will mainly focus on the needs of major national projects, strategic emerging industries and people's livelihood, accelerate the development of advanced automatic control systems, large-scale precision testing equipment, new instruments and sensors. In terms of key technologies in the industry, the following technologies will be focused on in the next five years: 1. Emerging sensor technology: as the basic component of the sensor network, sensors will have a very broad development prospect in the future. At present, new sensor technologies include solid-state silicon sensor technology, optical fiber sensor technology, biochip technology, gene chip technology, image sensor technology, all-solid-state inertial sensor technology, multi-sensor technology, etc. In this field, focus on the development of new principles, new effects of sensing technology, sensor intelligence technology, Sensor Network Technology, miniaturization and low power consumption technology, as well as the design, manufacture and packaging technology of sensor array and multifunctional and multi-sensor parameter sensor. The 12th Five-Year Plan will focus on smart sensors and key technologies. In this field, we will focus on the development of new principles, new effect sensing technology, sensor intelligence technology, Sensor Network Technology, miniaturization and low power consumption technology, as well as the design, manufacture and packaging technology of sensor array and multifunctional and multi-sensor parameter sensor. 2. Industrial wireless communication network technology: as a supplement to wired industrial communication network, industrial wireless communication network has been generally recognized. China has achieved certain results in industrial wireless communication networks, and it is possible to continue to strengthen development in the world. In this field, it is advisable to focus on the formulation of industrial wireless communication network standards and industrial wireless communication network authentication technology. 3. Functional safety technology and safety instrument: functional safety technology and safety instrument are new technologies recently developed in the world. Their purpose is to prevent industrial facilities from causing abnormal accidents, thus endangering the safety of people and equipment. This technology and related instrument products have received extensive attention from users. China's large-scale petrochemical engineering construction projects have stipulated that functional safety assessment must be carried out in advance. Unexpected accidents in industrial facilities in China occur frequently, so it is of great significance to study safety instrument technology. The key products to be developed in this field include: the development and application of control system reaching overall safety level SIL3, temperature transmitter, pressure/differential pressure transmitter, electric actuator/valve positioner, at the same time, it also includes the research of safety instrument system evaluation technology and the development of evaluation tools. 4. Precision machining technology and special technology: the gap between China's high-end testing equipment and foreign countries is largely the gap between precision machining and special technology. The current focus is on multi-dimensional precision machining technology, precision molding technology, precision machining technology for spherical and aspheric optical elements, grinding technology for Crystal optical elements, design and preparation technology for special optical films, precision grating scribing and copying process, special welding, bonding, sintering and other special connection processes, special chip processing technology, MEMS technology, full-automatic trace and trace sample analysis and processing technology, etc. 5. Functional components and application technology of analytical instruments: for key components of analytical instruments, such as detector, four-stage Rod, high-pressure pump, Valve, magnet, special light source and power supply, full-automatic sampler, long-life high-sensitivity electrode, middle-step grating, high-precision electronic extensometer and other key components to tackle key problems, improve the stability and reliability of the whole instrument. At the same time, spectrograms and databases for different application fields are developed. 6. Intelligent technology: intelligent technology is characterized by self-calibration, self-detection, self-diagnosis and self-adaptation; Have the ability of data processing of complex operation and error correction; It has the function of automatically completing the specified measurement task; Expert System software for scientific testing instruments and control systems, etc. 7. System Integration and Application Technology: at present, emphasis should be placed on the development of seamless connection integration technology between control systems of different manufacturers; The main supplier of automation equipment for large-scale projects should have project management technologies such as project planning, design, organization, procurement, acceptance, commissioning, etc. (Source: instrument network)
