摘要

Currently, indirect measurement using dynamic data from cable is widely used measuring thernnatural frequency of cable from the accelerometer attached to the surface and convert the data intorntensile force. However, it sometimes requires many hazardous works such as attaching the devicernon the surface of cable, writing it with data logger, etc, which could hinder the safety of workers inrnthe middle of cable.rnNew measurement system(laser vibrometer tension measuring system, LVTMS) using wirelessrnlaser-vibrometer is developed to eliminate the unsafe works and adjust the cable tension force asrnwell. Through the LVTMS, field engineers are able to figure out the cable tension force in no timernwhile standing on the field. In addition, the result by the previous method is to be compared. As arnresult, the LVTMS is proved to be accurate and reliable.
