Sensing technology is a bridge for technological development in various fields
With the development of modern science, sensor technology has been rapidly developed as a new discipline closely related to modern science, and has been widely used in industrial automation measurement and detection, aerospace technology military engineering, medical diagnosis, intelligent transportation and other fields. Use. Advances in technologies such as MEMS, laser technology, and high-tech materials have also led to diversification of sensor development. Let's take a look at the related content with the network communication Xiaobian.
A few days ago, thousands of sensors "put the pulse" Hubei Wuhan city bridge into a hot topic in the field of sensors. The first phase of the Wuhan City Bridge Smart Management System was put into use, and more than 1,000 sensors were ready to be healthy for more than 30 bridges. It is understood that the sensor covers 42 key bridges such as Wujindi Interchange, Parrot Interchange, Lumo Road Interchange, Happy Avenue Shahu Port Bridge, Aviation Road Interchange and Dadongmen Interchange. According to experts from the China Railway Bridge Science Research Institute, various types of sensors and acquisition equipment are installed on the bridge. Just like the hospital wears a 24-hour monitor for the patient, these sensors and acquisition devices will capture the structural condition of the bridge, the foundation settlement, and the vehicle monitoring in real time. Various monitoring data are stored in the cloud computing data center server through the Internet to realize automatic monitoring of the bridge around the clock.
In addition to Wuhan, Hubei, Anhui Hefei also built a city bridge safety monitoring system. 387 sensors help the prosperous avenue to cross the Nanpu River Bridge main span and Jinzhai Road viaduct safety, real-time monitoring of cable tension, strain, dip, displacement, deflection, acceleration, structural temperature and other changes. The collected data can be used to analyze the health status of the bridge at any time through the analysis of the development software, and provide support for bridge maintenance and maintenance to ensure the safety of the bridge. It is predicted that with the development of sensor technology and the industrialization of related products, more sensor products will be applied to infrastructure areas such as bridges, rail transit, tunnels, reservoir dams and ancient buildings in the future.
At present, sensor products have reached 10 categories, 42 categories, and more than 6,000 varieties. In terms of applications, whether it is aerospace sensors, or high-speed rail, aircraft, trains and other transportation facilities, has become a large platform for installing sensors. For example, the number of sensors used in ordinary cars exceeds 100/car, and the sensors used in high-class cars exceed 200/car. According to the national plan of “new energy vehicles will reach 5 million by 2020â€, new energy vehicles will bring sensors. A huge market for rapid growth. The wide application of sensors in the field of intelligent transportation will provide a more convenient way for accurate monitoring of the national transportation industry.
At the same time, sensors play a unique role in the pillar areas of food processing, environmental monitoring, water monitoring, industrial monitoring and other instrumentation industries. Some use biomaterials to simulate human skin, innovate the touch of sensors; some use MEMS technology to develop micro-intelligent sensors, which facilitates the integration of complex systems; some use high-precision laser technology to create laser radar, which facilitates real-time perception of the system. Peripheral obstacles and the environment, etc.
Sensor technology innovation has entered a period of breakthrough in recent years, especially in the field of biomedicine. Such as wearable new sensors, artificial hair sensors, socks humidity sensors, sticker sensors, bioluminescent sensors, skin sensor sensors, smart watch sensors, robot sensors, etc. to adapt to the ever-evolving technology of health monitoring, the latest breakthrough in the field of sensors Provided the possibility.
Today, with the industrialization and scale development of sensor technology, the government has also opened up a green development channel for sensors. In the “Three-Year Action Plan for Promoting the Development of a New Generation of Artificial Intelligence Industry†issued by the Ministry of Industry and Information Technology, smart sensors ranked first in the core foundation. The plan proposes to develop new types of smart sensors such as biological, gas and pressure that have broad market prospects. And stressed that by 2020, piezoelectric sensors, magnetic sensors, infrared sensors and other performance should be significantly improved. Pressure sensors that are within the required level are commercially available, and magnetic sensors with a weak magnetic field resolution of 1 pT are mass-produced.
At the same time, the sensor industry is closely following the new normal of the national economy, the national planning of the “13th Five-Year Planâ€, healthy countries, and countries rich in science and technology, providing a constant source of power and imagination for sensor technology innovation. On this basis, how to develop sensors that meet the market trends and requirements of the plan, how to make the sensors stand out in the same kind of instruments has become a new topic for researchers. For instrument manufacturers and distributors, only by following the trend of the times, can we have the right direction, master the core technology, and be in an invincible position. Only by grasping the development opportunities and focusing on R&D and market demand can we Let the sensor industry take it to the next level!
