With the advent of the new technological revolution, the world began to enter the information age, sensors as the main way and means to obtain information in the field of nature and production, the sensor industry is an indispensable key driving force in today's field of science and technology, known as the nerve antennae of modern intelligence, is an important part of the era of the Internet of Everything, through the perception, measurement and monitoring of variables in the environment, the real world information into electrical signals or digital data, providing valuable data input for enterprises.
According to Statista, the global market size in 2022 is:2512.$900 million(About 1.)79 trillion RMB). Affected by the epidemic, the global sensor market has experienced significant fluctuations and the year-on-year growth rate in 2022 is %. In contrast, the growth rate of the Chinese market is relatively stable, with a three-year growth rate of %, respectively, maintaining around 20%. In addition, the proportion of the Chinese market in the global sensor market remains atUp and down, the share in the global market is also relatively stable.
There are many types of industrial sensors with different principles, and there is currently no unified classification standard. Generally speaking, industrial sensors can be classified according to the following principles: according to the use scenario, they can be divided into photoelectric sensors, proximity sensors and safety sensors; According to the common detectable natural phenomena, it can be divided into light, electricity, electromagnetic, thermal, temperature, magnetic, mechanical motion, radiation and other industrial sensors; According to the form of output signal, it can be divided into digital industrial sensors and analog industrial sensors. Distinguishing industrial sensors according to their usage scenarios is a more common classification method in the market today.
From the specific downstream point of view, sensors are mainly focused on consumer products and industrial products, with home appliances and automobiles accounting for 23 respectively15% and 1852%, accounting for the main part. In addition, the use of smart sensors in the fields of industrial control, medical, aircraft and ships is also more common. In modern industrial production, especially in the automated production process, various sensors should be used to monitor and control various parameters in the production process, so that the equipment works in a normal state or the best state, and the products can reach the best quality. Industrial control refers to industrial automation control, which is mainly realized by the combination of electronic and electrical, mechanical and software, that is, industrial control (factory control), or factory automation control (factory automation control). It mainly refers to the use of computer technology, microelectronic technology, and electrical means to make the production and manufacturing process of the factory more automated, efficient, accurate, and controllable and visible.
The core of the sensor is data acquisition, that is, the various parameters (physical, chemical or biomass) of the measured object are appropriately converted through various sensitive components, and then through the steps of signal conditioning, sampling, quantization, encoding and transmission, and finally sent to the computing system for processing, analysis, storage and realization. In the long run, with the upgrading of electronic materials and microelectronics technology, the circuit structure of data acquisition systems presents two major development trends: first, multiple sensor chips can be integrated into packaging, or more signal channels and functional modules can be integrated in the analog front-end to cope with the scenario of measuring multiple targets at the same time and simplify circuit design; The second is SoC (System-on-a-Chip), which integrates any two or three of the sensitive components, analog front-end, and MCU on a single chip. As technology advances and matures, sensors will become smaller, consume less power, be more accurate, and be more reliable and durable, allowing them to be used in a wider range of applications.
Sensors are the bridge to open up the information flow between the physical world and the digital world, and the key to promoting the deep integration of informatization and industrialization is to leave all kinds of sensors, the physical world and the digital world are isolated, and the role of digital technology in empowering economic and social development will be greatly weakened. As a highly technology-intensive product, sensors have strict requirements for raw materials, key technologies, manufacturing processes, tools and software, etc., and high-end sensors in various fields are the same as industrial software, which are the killer features of industrial competition, curbing the lifeblood of industrial development and controlling the value distribution of the industrial chain.
Industry 4The advent of 0, the application of intelligent sensors in the industrial field is more and more extensive, as a device that can perceive, collect, process and transmit information, intelligent sensors can realize real-time monitoring and control of the industrial production process, with the help of digital technology and tools to improve production efficiency, improve product quality and innovation capabilities, through the collection and transmission of a large number of production data by intelligent sensors, can help enterprises to optimize and upgrade the production process, improve the competitiveness and innovation ability of enterprises, Transform traditional manufacturing into digital manufacturing. Smart sensors have the advantages of strong real-time, high accuracy, high reliability, easy installation and maintenance, but at the same time, they also face challenges such as data security, standardization, and the cultivation of first-line brand smart sensors, which need to realize the maintenance and maintenance of equipment, reduce equipment failure and downtime, and improve the service life and efficiency of equipment.
With the development of artificial intelligence and Internet of Things technology, the application scenarios of intelligent sensors will be more diverse, sensors as a bridge between objects and networks, in the core position of the entire architecture system of the Internet of Things, with the continuous growth of networking nodes, the number of intelligent sensors and the degree of intelligence requirements are also constantly improving, coupled with policy support, technological progress and growing market demand, China's intelligent sensor industry will usher in more opportunities and development space.
The stability and reliability of the sensor are crucial, and problems with stability and reliability will not only cause errors in perception acquisition, but also lead to incorrect decisions in the system and even major safety incidents. Domestic sensor enterprises generally have a small scale, lagging technological innovation level, unsystematic products and other states, in the sensor product standardization, performance normalization, functional integration, structure standardization in the slow progress of the process, materials, technology, technology and other innovation, management and control capabilities, resulting in low sensor quality, affecting product stability, reliability and durability.
Compared with foreign countries, there is a large gap between China's sensor companies in product quality, technical process, production equipment, enterprise scale, market share, comprehensive competitiveness, etc., especially in key technologies, processes, materials, tools and other fields. However, comparing the development history and research status of sensor technology, it can be seen that with the rapid development of science and technology and the increasing maturity of related conditions, sensor technology has gradually received more attention from more people, and the research and development of sensor technology today, especially the development of new sensor technology based on optoelectronic communication and biological principles, has become an important symbol and driving force to promote the progress of the national and even the world's information industry.
In the future, enterprises need to strengthen talent training and introduction, break through multi-sensor integration and data fusion technology, develop multi-functional, multi-sensor parameter composite sensors, continue to promote intelligent sensor supporting software algorithms, high-performance batteries and other technical research, continue to improve the ability of intelligent sensor integration and innovation, strengthen the layout of intelligent sensor R&D and design, processing and manufacturing, packaging and testing, materials and equipment, etc., and consolidate the industrial foundation support for sensor product innovation, focusing on intelligent terminals, high-end equipment, Key areas such as transportation and logistics, energy and water conservancy, trade and circulation, agriculture and animal husbandry, and ecological environment should be applied to the demand for sensors, cultivate the ecology of the intelligent sensor industry, strengthen the R&D, design and industrialization of intelligent sensors, and promote the transformation of enterprises to digital manufacturing.
