In order to detect geometrical parameters of contact cable in real-time and effectively,ensure the running of railway and prolong the using time of laser cable,the laser measurement system of contact cable about geometrical parameters is proposed. Distance sensor,angle sensor,displacement sensor,CCD camera and embedded data pro-cessing technology are applied to this system. The architecture and measurement principle of the system are intro-duced,the mathematics model and the error range are described in detail,and the main parameter measurement in-determination degree of the system are analyzed and evaluated. Compared with previous measurements,orientation can be implemented in this measurement system,besides the measurement of railway contact net’s parameters can speed up,whose accuracy can reach ±5 mm.
