Design And Realization Of Track Geometry Measurement System

Track geometry measurement system is testing rail disease, guide railway track maintenance and guarantee the train operation of the importance of safety technology. The developed countries in the world are committed to the development of high-speed rail geometry measurement system, in order to ensure the safety of railway transportation. On the base of the introduction and absorbing foreign advanced detection technology, our country develope independently the GJ-4type track geometry measurement system. With the rapid development of China’s railway transportation, safety requirements improved, GJ-4track geometry measurement system gradually exposed the shortcomings and problems, this paper puts forward the existing problems and the reform plan, the design and implementation.This paper introduces the track geometry measurement system detection principle, the structure and the various parts. According to orbit for GJ-4type geometric measurement system, the structure type gauge measurement system to replace rail photoelectric servo type gauge measurement system to track; In the original detection system was designed based on the new data transmission; A relational database, for detecting data offer more convenient and practical way of storage; Upgrade waveform display, edit and print statements, and other data processing system. The grey system grey relational grade analysis of the data, and the calibration of the waveform deviation cause waveform deviation.For artificial fixed mileage work tedious, larger deviation of the problem, design using the GPS positioning system to be automatic correction mileage the system. Finally design and realize the software of the system.Application of this paper improves technology to DJ998385track inspection car to improve the implementation. The actual operation shows that, improve the track geometry measurement system stability and security, reform, the effect is good. The main railway line to ensure transportation safety, improve the quality of the railway line has played an important role.
