Abstract: According to the principle that cable tension can be measured by vibration frequency method, the simplified cable tension measurement system based on SCM was designed, and both whole hardware and whole software design systems were finished. The whole software included the processing program about MCU, IIC bus program flow, frequency spectrum analysis, key control, as well as LCD module and host computer software. Finally, the cable tension measurement experiment with Dafosi Bridge of Yangtze River was carried out, and the experimental results showed that this measurement system was applicable, portable and easy to use.

Key words: bridge engineering, cable tension, vibration frequency method, cable tension measurement experiment, software system
