With the development of modern science, sensing technology has developed rapidly as a new discipline closely related to modern science. It has been widely used in industrial automation measurement and testing, space technology military engineering, medical diagnosis and intelligent transportation Use. MEMS, laser technology, high-tech materials and other technological advances, but also for the development of sensors showed a variety of trends.
In addition to Wuhan and Hubei, Anhui Hefei also constructed a city bridge safety monitoring system. 387 sensors help bustling Avenue Crossing the main span of Nanhe River Bridge and the viaduct of Jinzhai Road to monitor the changes of cable force, strain, inclination, displacement, deflection, acceleration and structure temperature in real time. The collected data can analyze the safety of the bridge at any time by analyzing the software development and provide support for the maintenance and repair of the bridge to ensure the safe control 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 the fields of bridges, rail transit, tunnels, reservoir dams, ancient buildings and other infrastructure in the future.
At present, the sensor products have reached 10 categories, 42 sub-categories, more than 6,000 varieties. In applications, whether it is aerospace sensors, or high-speed rail, aircraft, trains and other transport facilities, have transformed into a large platform for the installation of sensors. For example, there are more than 100 sensors used in ordinary cars and more than 200 sensors used in limousines. According to the national plan of "keeping 5 million new energy vehicles by 2020", new energy vehicles will bring the sensors the huge market of rapid growth. The wide application of sensors in the field of intelligent transportation will provide a more convenient way for the accurate monitoring of national transportation.
At the same time, sensors also play a unique role in the pillars of the instrumentation industry, such as food processing, environmental monitoring, water monitoring, and industrial monitoring. Some use of biological materials to simulate human skin, innovative sensor touch; some use of MEMS technology to develop micro-intelligent sensors, which is conducive to the integration of complex systems; some use of high-precision laser technology to create a lidar, which will help the system real-time perception surrounding obstacles and the environment and so on.
