Abstract

The invention provides an embedded wireless passive bolt tightness state monitoring system based on a surface acoustic wave technology. The embedded wireless passive bolt tightness state monitoring system comprises a measuring module, a receiving module and a bolt body, wherein the measuring module is in signal connection with the receiving module; the measuring module comprises a sensor sensitive device and an antenna; the sensor sensitive device is prefabricated in the bolt body, one end of the antenna extends out of the bolt body, and the other end of the antenna is connected with the sensor sensitive device, so the wireless passive bolt tightness state monitoring system based on the surface acoustic wave technology can monitor tightness of a bolt in real time.

Description

technical field [0001] The invention relates to the technical field of screw tightness monitoring, in particular to an embedded wireless passive bolt tightness monitoring system based on surface acoustic wave technology. Background technique [0002] The main function of the screw is to connect two workpieces together and fasten them. Screws are used in general equipment, such as mobile phones, computers, cars, bicycles, various machine tools and equipment, almost all machines Screws are needed. Bolts are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws for TVs, electrical products, musical instruments, furniture, etc.; large screws for engineering, construction, and bridges. Screws, nuts; transportation equipment, aircraft, trams, automobiles, etc. are used together with large and small bolts. Screws have important tasks in industry. As long as there is industry on the earth, the function o...
