Industrial interconnection "new infrastructure", the opportunity for sensors has come

at the just concluded national two sessions, industrial interconnection was once again written into the government work report, and upgraded from building an industrial interconnection platform to a more comprehensive development of industrial interconnection, actively promoting the docking and cooperation of international production capacity in nonferrous metals, petrochemicals, building materials and other fields. As the eye, ear, nose and tongue of industrial equipment, sensors are considered to be the foundation and core of industrial interconnection. What role do sensors play in industrial interconnection? What are the new requirements of industrial interconnection for sensors? What opportunities will the construction of new infrastructure industrial interconnection bring to the sensor industry

sensors and industrial interconnection complement each other and promote progress.

Industrial interconnection is the product of the deep integration of the new generation of information technology and manufacturing. Through the comprehensive interconnection of people, machines and things, a new type of production and service system with all factors, all industry chains, all value chains and all connections is built. Industrial interconnection is the interaction of data flow, hardware, software and intelligence

Li Weiping, chairman of Nanjing Gaohua Technology Co., Ltd., told China Electronics News that sensors are key components of automated intelligent devices, which perceive various state information of products, equipment and industrial environment through looking, smelling, listening and cutting. It includes various visual sensors, infrared sensors, ray sensors, smelling sensors, gas sensors, listening sensors, and all kinds of pressure, temperature, humidity, vibration, displacement sensors. He said that one of the cores of industrial interconnection is the intelligent monitoring of industrial processes and industrial environment. The application of sensor and wireless sensor network technology to intelligent monitoring is conducive to the optimization of industrial production process technology. At the same time, it can improve the ability and level of production line process detection, real-time parameter acquisition, production equipment monitoring and material consumption monitoring, and continuously improve the level of intelligent monitoring, intelligent control, intelligent diagnosis, intelligent decision-making and intelligent maintenance of production process

since the 1980s, there has been a wave of sensor fever in the world. All advanced industrial countries attach great importance to the research, development and production of sensing technology and sensors. The production of sensors and their systems has become an important emerging industry. In an interview with China Electronics News, Zhang Jianqi, deputy general manager of Xi'an Aerospace Automation Co., Ltd., said that in the process of industrial interconnection development, it is difficult to measure the real σ e. The stress when the residual elongation of the sample reaches 0.01% of the original gauge distance is often taken as the elastic limit, and σ 0.01 means that a perfect industrial sensor group system must be built for the current industrial interconnection, because the era of industrial interconnection is to connect machines, equipment, personnel, materials, etc. through cloud computing, big data and other new generation information technology, at the same time, collect, process and analyze data, provide decision-making basis for industrial production, and finally improve the intelligent level of manufacturing and industrial enterprises

therefore, in the era of industrial interconnection, sensors are the source of network interconnection data and the nerve endings of industrial interconnection, providing the most basic data support for the whole ecological construction of industrial interconnection. If we describe a system or a slightly intelligent system, the closed-loop process of cyber spatial data flow as state perception - real-time analysis - autonomous decision-making - precise execution - learning and improvement, then the sensor provides the most front-end, that is, the most initial source of data, and provides data support for the system

industrial interconnection and sensors complement each other and promote each other. Xu Jing of the industrial interconnection Research Office of the Institute of informatization and software industry, China Academy of electronic information industry development, proposed that sensors are the collection entry of industrial interconnection data and the foundation and key components of industrial interconnection. The industrial interconnection platform provides a platform for data cleaning, storage, exchange and Value Mining for the data collected by sensors, and promotes the application of data in a wider range, wider fields and deeper levels

industrial interconnection poses new challenges to sensors

the vigorous development of industrial interconnection not only brings great opportunities to sensors, but also puts forward new requirements for sensors

Li Weiping believes that the development of industrial interconnection has obvious stages from low-level to high-level. No matter what stage of development, it is inseparable from the wide application of sensors. The requirements for sensors are different in different stages of industrial interconnection development. In terms of current applications, sensors are mainly used by enterprises for data collection and analysis of the basis of industrial interconnection. With the deepening of the development stage of industrial interconnection, the requirements for the accuracy of sensors and related technologies will be higher and higher in the future, mainly reflected in the higher requirements for sensitivity, stability, reliability and so on. Li Weiping said

Zhang Jianqi further analyzed the development direction of sensors in the era of industrial interconnection. He pointed out that sensors will develop in the direction of intelligence, miniaturization, multifunction, low power consumption and high precision. First of all, the era of industrial interconnection requires the interconnection of all things, which requires that the cost of sensors as data aggregation sensors should be low. Only low-cost sensors can truly realize the interconnection of all things. Konghonning, the father of German industry 4.0, also pointed out that low-cost sensors are a necessary condition for the realization of industry 4.0. Secondly, under the requirements of low-cost sensors, it is also necessary to ensure that the sensing accuracy of sensors meets the requirements of industrial scenes and the accuracy of sensing data. Thirdly, the era of industrial interconnection puts forward higher requirements for sensor power consumption. Only by ensuring that the power consumption of sensing components is low enough, can we ensure that the goal of energy saving and consumption reduction of sensing terminals under the interconnection of all things be achieved. At present, sensing terminals based on bioenergy, solar energy and other power supply are emerging, providing a new technical support for the development of sensors in the era of industrial interconnection. Finally, in order to ensure the data security and reliability of industrial interconnection, more and more industrial scenes put forward high requirements for the data security and reliability of sensor equipment. The high reliability of sensors is a major challenge for the development of sensors in the era of industrial interconnection, especially the recent frequent network security problems put forward new topics for the security characteristics of sensors

in addition, traditional sensors are being upgraded to intelligent terminals at an accelerated pace, laying the foundation for building a new end edge Cloud Architecture. Zhang Jianqi told that with the massive access of low-cost sensors, massive amounts of data will be generated. If these data are sent directly to the cloud without processing, it will have disastrous consequences for the cloud. Therefore, traditional sensors are being upgraded to intelligent terminals at an accelerated pace, and reliable and reliable data will be uploaded to the cloud through edge side optimization and processing

Xu Jing believes that industrial interconnection puts forward higher requirements for sensor acquisition density, operating conditions, and autonomy and controllability. In terms of acquisition density, industrial production requires high-frequency, high-throughput, lossless and full-time stable data acquisition capabilities. In terms of operating conditions, unlike sensors in the consumer field, sensors in the industrial field need to have the ability to withstand high temperature and extreme cold, salt corrosion and acid-base corrosion, humidity, flying sand and dust, violent vibration and impact, and noise. In terms of self-control, at present, the hollowing out of China's sensor industry is serious. 90% of high-end industrial sensors are monopolized by foreign manufacturers. Most Chinese manufacturers are in the middle and low-end fields, and there are data security risks. In the past, data leakage was limited to a plant or an enterprise. Under the background of full interconnection of industrial interconnection, data leakage may extend to the entire industrial chain, causing the loss of economic benefits of the entire industry

the construction of industrial interconnection of new infrastructure can also take 5 mm or 20 mm steps to drive the development of sensors according to needs

as an important part of new infrastructure, the construction of industrial interconnection will have an all-round, deep-seated and revolutionary impact on the sensor industry, and China's sensor industry will usher in unprecedented development opportunities. Data show that this year's national peel strength: peel strength is an important indicator to measure the bonding performance of self-adhesive labels. The industrial Internet market is expected to grow by 7%

Zhang Jianqi told China Electronics News that in the construction of industrial interconnection of new infrastructure, the focus will be on enhancing the interconnection perception ability of industrial field equipment, strengthening the collection of key data and information of underlying equipment, and improving the perception sensitivity of the underlying nerve endings of industrial interconnection, which will promote the deep integration of the industrial chain at various stages of sensor manufacturing, design and development, optimization and iteration, and promote the rapid growth of the sensor industry ecosystem, So that the sensor industry continues to develop and expand, in order to better promote the high-quality development of the industrial interconnection industry

the development of industrial interconnection has brought a huge market to China's sensor industry, driving the rise in sensor demand. Xu Jing told China Electronics News: there are small, scattered, chaotic and weak problems in China's sensor industry. China's sensor enterprises can take this opportunity to seize market opportunities, enhance enterprise strength and expand industrial scale

the sensor industry chain includes upstream components, chips, circuits, microcontrollers, coating materials and other enterprises, midstream packaging and manufacturing enterprises, and downstream application enterprises. Xu Jing believes that industrial interconnection, as a hub connecting all elements, the whole industry chain and the whole value chain, plays a very important role in promoting the upstream and downstream collaboration of the sensor industry chain and forming industrial synergy
