Abstract
Based on the analysis of the current railway track parameters measurement system, a digital system based on embedded processor is designed. The paper introduces the principle of the system , structure and methods. The system is still based on the deviation detection principle of three point method, using high brightness light source as a measurement point, in combination with linear CCD imaging features, completed the orbit measurement system of the digital processing, and through the network to complete the communication with PC. The photoelectric measuring system is realized in trajectory parameters of high accuracy and real time measurement; Also for the future development of tamping on railway cars plays a positive role.
