| Abstract: | The portable track detecting instrument facilitates effective inspection of track smoothness. The speed measuring module is an important component of the system. The present way of measuring speeds has serious defects, such as that the positioning mistake is too large. To solve this problem, a new type track-detecting instrument using the Global Positioning System is studied. The paper discusses the hardware and software designs of the new system,and the key technologies of using the GPS, and also experimental analysis. The new system improves the accuracy of failure-point positioning. It helps to find the failure points more quickly and accurately, thus increasing the efficiency of maintenance. |
