Abstract :
Measuring the cable tension force is important to cable-stayed bridges. According to frequency method, this paper advanced a new wireless measurement system based on LabVIEW. During signal processing, DTFT method was used to obtain precise fundamental frequency. Experiment has proved that the system can fulfil the fieldwork requirement of cable force measurement very well.
