基于Zigbee技术索力测试系统的研制与开发

able force decides the working state of the cable-stayed bridge directly. Measuring the cable force of the cable-stayed bridge through some exact method is the guarantee to construction and operation. This paper summarises the methods and their theories usually uesed in cable force of cable-stayed bridge measuring. The research and development of wireless cable force testing system are based on MEMS, the general equation is first derived using the frequency method of cable force, through the experimental frequency changes of cable force to calculate the cable force size. Finally, before and after the installation of steel box girder cable force change value to prove the system can be used to test the size of the cable force .
