Sensor technology tamps the cornerstone of intelligent manufacturing and promotes the intelligent upgrading of industry.

Since 1980s, there has been a sensor craze all over the world, and developed industrial countries attach great importance to sensor technology and sensor research, development and production.

After years of development, sensor technology has become an important field of modern science and technology, and the production of sensors and their systems has become a new industry.

For manufacturing industry, intelligent sensor is the foundation of intelligent manufacturing.

In the process of intelligent manufacturing transformation, a large number of traditional manufacturing industries widely use sensors in production, inspection, logistics and other fields.

The sensor can meet various application requirements in the factory manufacturing environment.

Including predictive maintenance and automation of mechanical production equipment, asset tracking and supply chain, real-time monitoring and calibration, vibration detection and tamper prevention, oil and electricity consumption calculation and water level monitoring for flow calculation.

MEMS sensor is the heart of smart factory.

From this point of view, it is a powerful tool for industrial robots to do magic, so that the production process of products can continue to run, and workers can stay away from production lines and equipment to ensure personal safety and health.

It is predicted that the compound annual growth rate of MEMS in the industrial market will exceed 7% in the next six years.

At present, China's sensor enterprises are trying to catch up with foreign enterprises, and regional sensor enterprise clusters have emerged, mainly concentrated in the Yangtze River Delta region, and gradually formed a regional spatial layout dominated by central cities such as Beijing, Shanghai, Nanjing, Shenzhen and Shen An.

Among them, the Yangtze River Delta region is centered on Wuxi, Shanghai and Nanjing, and gradually forms a relatively complete sensor production system and industrial support including gas sensitivity, thermal sensitivity, magnetic sensitivity, image, weighing, photoelectricity and temperature.

The sensor market in China is growing continuously.

According to statistics, in 20 18, the sensor market in China reached147.2 billion yuan, a year-on-year increase of 13.23%. It is estimated that the sensor market in China will exceed 200 billion yuan in 20021year and will grow to 258 billion yuan in 2023.

Sensing detection technology is one of the indispensable key technologies of modern scientific production equipment, which can perform functions such as information acquisition, information transmission, information conversion and information processing, so that the physical quantities we want to detect can be displayed in a concise and clear form.

At present, geomagnetic sensor detection technology is considered as one of the most advanced traffic data acquisition technologies, and has been applied in most cities in China.

In short, the geomagnetic detector is based on the influence of ferromagnetic substances contained in the vehicle itself on the geomagnetic signal in the vehicle presence area, which makes the earth's magnetic field lines in the vehicle presence area bend and detect.

When the vehicle passes near the geomagnetic sensor equipment, the geomagnetic sensor can sensitively sense the change of the signal, and the relevant information of the detection target can be obtained through signal analysis.

The design technology of sensor includes many disciplines, theories, materials and process knowledge, and it is very difficult to break through.

At present, some key technologies of sensors have not been broken through in China due to the shortage of talents, high research and development costs and fierce competition among enterprises.

However, driven by the market and policies, the ecology of China's sensor industry is becoming more and more complete, and key enterprises are involved in manufacturing and design. Some scientific research institutions have also established relevant service platforms to boost the innovation and development of the industry.

China's digital economy is already a colossus, accounting for about 35% of GDP, with a total amount exceeding 30 trillion yuan.

Sensors are the basic fulcrum of digital economy.

It is worth noting that the rise of big data, Internet of Things, cloud computing and artificial intelligence applications has promoted the transformation of sensing technology from single-point breakthrough to systematic and systematic collaborative innovation, and has become a strategic highland for the layout of developed countries and multinational enterprises.

I believe that in the near future, after overcoming the related problems, the development of sensor industry in China will achieve even more gratifying results.
