Design of Wireless Measuring Terminal for Absolute Position and Displacement of Railway Track Based on PSD Position Sensor
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 5
Abstract
With the large-scale application of seamless rail in China, the workload of front-line railway maintenance workers has also greatly increased, and the traditional manual "two times measurement method" has been unable to meet the requirements of the rapid operation of patrol workers. In this context, in order to realize the accurate and rapid measurement of the absolute position and slight creeping displacement of motion direction of seamless railway track, a wireless position measuring device based on PSD position sensor for railway track absolute position and displacement is presented. The device consists of three parts, such as a wireless sensor terminal, a mobile handheld terminal and a PC host computer. The functions of railway track absolute position and the micro creeping displacement of seamless railway track in the direction of train running measurement, data acquisition and statistics, over limit warning and quality evaluation of patrolling workers can be realized. The utility model has the advantages of high observation precision, long time work in the field, high efficiency, small volume, low power consumption, automatic data statistics and analysis, etc. The utility model has wide application prospect and great economic and social benefits.
