Re understanding of sensor industry under the inte

Guoyuansheng: recognition of sensor industry under international strategic competition editor's note: sensors are multidisciplinary high-tech polymers, known as industrial handicrafts. At present, sensors are developing towards intelligence, miniaturization, multi-function, low power consumption, high precision and so on. During the 14th Five Year Plan period, China's intelligent sensor industry will make major breakthroughs in technological innovation and industrial scale, and the innovation ability of design and manufacturing technology will be greatly improved. The capabilities of simulation, MEMS process, wafer level packaging, personalized testing and software and hardware integration will reach the international advanced level, and the industrial scale will exceed 100 billion yuan, becoming a new basic industry supporting industrial interconnection and intelligent manufacturing. To this end, this newspaper specially opened a column on the prospects of the sensor industry during the 14th Five Year Plan period, and invited Zhao Ping, director of the International Trade Research Department of the Research Institute of the China Council for the promotion of international trade, to say that industry experts feel the pulse of the sensor industry, and comprehensively sort out the development status of the domestic sensor industry from technology, application and market, so as to provide strong support for the construction of new infrastructure and the rapid development of a new generation of information technology

in the digital economy system or system architecture, the blood that runs through or flows is data. In the whole information system composed of perception, transmission and processing, storage, feedback and execution, data is always transmitted. However, as one of the core technologies of digital economy, the industrialization of sensors is worrying. It seriously restricts and affects the function and efficiency of data acquisition and acquisition. It has become the biggest obstacle and bottleneck affecting and restricting the development of digital economy, which should be paid great attention from the strategic aspect

recognition of strategic positioning

according to the current development status and problems of China's sensor industry, combined with the comprehensive factors of the upcoming 14th five year plan, the adjustment of industrial structure and the transformation and upgrading of manufacturing industry, the impact of the digital economy after the epidemic, and so on. As the only functional device of data acquisition, sensor is the basic and core technology of information technology

as we all know, information technology is composed of three technologies: perception, transmission and processing, namely, computer technology, communication technology and sensor technology. The hardware of the information system is composed of three technologies plus information storage, feedback and execution, and the information transmitted in the whole system is data. If a person is regarded as a complete information system, the information that five senses and skin interact with the outside world is data information, and the sensory organ is the data acquisition device, which is the core of data acquisition. In reality, the corresponding physical device is the sensor product, so the sensor is also called the electronic facial features, 5g and other communication technologies are called the human nervous system; The computer is called the brain of the human body, which is responsible for and undertakes the function of data processing

therefore, we should raise the sensor to the height of national strategy and re recognize it, so as to return to value and receive its due attention. Like supporting integrated circuits and display technology, the strategic position of sensors should be highlighted in the national strategic planning, and corresponding supporting policies (special support, tax relief, market access) should be given. Continuous support is to evaluate the wear resistance of friction materials, so as to make up for the shortcomings of industrial technology and policy deficiencies

recognition of technology and process

although sensors are the fusion of multi disciplines, multi technologies and multi fields, involving basic disciplines of physics, chemistry and biology, they are closely related to almost all secondary disciplines, such as materials, machinery, electronics, mathematics, computer software and hardware, measurement, semiconductors, from the whole industrial chain process of sensitive mechanism, process technology, structural design, finished product testing, market application, etc. The production process is also extremely complicated, known as the production of industrial handicrafts. However, blindly pursuing the indicators of high precision, high reliability and high stability of products greatly increases the technical difficulty of production process and the level and ability of industrialization. The economic benefits are not good, and the innovation achievements have little effect. Therefore, the multi-function composite of single device and the integrated combination of multiple devices are the trend of sensor technology innovation and development

it is a common problem in the field of scientific research that the sensor pursues high precision and achieves the best of its products. However, in the supporting market and application scenarios, what is often needed is the reliability and stability indicators, as well as the requirements for the use cost. The requirements for a single indicator of the sensor are reflected through the overall function of the system. Even a single sensitive component can sense two or more physical and chemical quantities at the same time; Multiple physical and chemical quantity sensitive components are integrated and combined on the same chip; Or it can be combined into a component (module) to form an intelligent module. According to the application scenario data measurement requirements, combined with multi-dimensional recognition and software algorithm, to make up for many problems caused by the single pursuit of high precision

therefore, while the eight major sensing elements adopt common MEMS process technology to improve the industrialization level, efforts need to be made on the product use function and technical standards and specifications. Multiple sensitive elements are combined, combined with software processing, to form a micro system of multi-dimensional testing and multi parameter fusion, so as to make up for the difficulty of industrial scale production due to the unilateral pursuit of high precision, so as to reduce the difficulty of high-precision production and the cost of finished product testing, and improve the economic benefits of scale production

recognition of industrialization ability

at present, there are about 26000 different types of sensors in the world, forming a current situation of multiple varieties and small batches. Therefore, the industry is too scattered and lacks norms and standards from R & D design, functional indicators, shape structure and application scenarios, resulting in innovation for innovation. It not only causes waste, increases the difficulty of industrialization, but also brings more complexity to market application

the existing sensor enterprises are scattered all over the country, and the industrial chain coordination is difficult; The production process is cumbersome and complicated, and there are many technical points; Tooling fixtures are unique and expensive; The scale of enterprises is small, and it is difficult to gather and cultivate talents. These have led to the embarrassment and helplessness of industrialization for a long time. What's more, confusing sensors with integrated circuit products, technologies and processes and classifying them into integrated circuits leads to a long-term lack of inclination and support from industrial policies

recognition of market synergy and integration

the total size of the sensor market at home and abroad has exceeded 187billion US dollars last year, and has increased at an average rate of more than 10%. The market in some fields has shown explosive growth. However, there are obstacles between manufacturers and users that are difficult to overcome, and their understanding of technology and the needs of each other are also different, so it is difficult to find effective methods and ways to connect and break through. From the user's point of view, there are unpredictable technical parameters and structural choices, which are difficult to understand at the moment, resulting in the phenomenon of not being able to use and not daring to use, and there is no detailed content. It can't be started after adding materials and special use requirements in different scenarios. From the perspective of production, manufacturers are not sure about the scene data model of market applications. Products lack flexible design from structure to performance, so it is difficult to provide personalized and accurate parameter indicators, and it is also difficult to understand what users need to use, how to use it, and why they choose it. From a technical point of view, the real scene and state are dynamic, changeable and complex. What parameters to choose is not only considered from the perspective of on-site needs, but also needs the overall design of the system. Therefore, at the data collection site, there are different opinions on the type, structure and parameter selection of the sensor. The product is formaldehyde free, fire-proof and moisture-proof, free of pests, and the phenomenon of "each holding one word" occurs frequently. It can be said that it is south of the tune, or even the opposite, with great differences. However, the type of sensor selected is crucial to the performance and intelligence level of the system or device

in addition, users have great prejudice and differences in treating domestic enterprises and products. Under the same circumstances, users often choose foreign products whose prices are much higher than those of domestic enterprises. Especially in resource monopoly industries, in order to reduce and avoid trouble, it is a common phenomenon that if you can buy foreign products, you must not use domestic products. In addition to the prejudice against users' domestic enterprises, sometimes harsh additional conditions and complicated procedures and processes also deter enterprises. Therefore, even if domestic enterprises follow up for a long time, they will return in vain, which has gradually raised the entry threshold and industry barriers

it can be seen that the obstacles and bottlenecks between production and use have become a major obstacle to the development of industrialization. Therefore, sensor products should not only develop in the direction of normalization, standardization, intelligence and networking of parameters and indicators, but also establish the collaborative innovation relationship between production and application, establish the information channel and technology research and development platform of mutual trust, exchange and communication between industry and application, and remove the obstacles on the road for the development of sensor industrialization

recognition of the demand for compound talents

talent collaboration is the premise of technology integration and the basic guarantee of industrialization. However, at present, there is a lack of entrepreneurs or leading enterprises in the sensor industry to lead and drive, and there is a lack of high-end talents for compound technological innovation and industrialization within the enterprise, especially international leading talents, which makes it difficult to form industrial restructuring and resource integration

therefore, the cultivation and accumulation of basic research talents, technical compound talents, industrialization engineering talents and talents with international vision are of great importance. For the sensor industry, entrepreneurs with strategic mind and market-oriented ability are the top priority

suggestions and ideas for industrialization

the development problems of the sensor industry are concentrated as follows: multiple varieties and small batches, large product dispersion, low industrial concentration, small enterprise scale, and few specialized and leading enterprises. Thus, there are five problems: lack of people, lack of money, lack of technology, lack of market, and insufficient attention

today, with the rapid development of digital economy, people must recognize the prominent contradictions and problems in China's industrialization, and should do a good job in strategic positioning and top-level design, allocate corresponding resources, and sort out norms and standards in combination with China's structural adjustment, transformation and upgrading, the requirements of the 14th five year plan, and the specific impact of epidemic, international friction and upgrading and environmental change. In fact, it is not difficult to realize the industrialization of sensors in China. The industrialization of infrared thermopile sensors is the best example

specific suggestions are as follows: first, clarify the strategic positioning and do a good job in top-level design. Take the industrialization of sensors as the core of the foundation of digital economy, and raise it to the height of national strategy, and continue to cultivate and support it at different levels and stages. Second, explore the problems in the industry and make up for the shortcomings and bottlenecks. Starting with the specific problems in the industrial system and chain, we should solve the problems of technology, industrialization bottleneck, the contradiction between market supply and demand, the leading role of talents (especially entrepreneurial talents), and the optimal allocation of resources. Third, policies should be accurately matched and resources should be continuously allocated. In combination with local industrial supporting policy resources, set up special national industrialization policies, give preferential treatment in terms of Taxation, and continue to guide and guide industrialization. Fourth, continuously evaluate the effect and adjust the implementation method in time. Conduct segmented evaluation and assessment according to the industrialization level, stage and step, and timely correct and adjust the implementation steps according to the real-time status to avoid causing
