应用GPS/GPRS技术的列车检测系统研究

Research of vehicle monitoring system based on GPS/GPRS technology

随着列车运行速度的提高,实施列车监控具有十分重要的意义。利用计算机通讯技术、GPS技术(全球定位技术)和GPRS技术(通用无线分组业务)实现列车定位,对影响行车安全的因素进行在线检测和信息的集中显示、存储和故障报警,并可进行历史数据的查询。通过GPRS实现数据的无线传输和资源的共享。主要介绍了系统各部分功能及其实现以及走行部故障报警模型的建立,通过实际线路中的试验应用,证明该系统有一定的可靠性和实用性。根据一段时间运行试验数据可优化某些故障判据,逐渐完善系统。

With higher running speed of vehicles,it becomes more and more important to monitor the nmning status of vehicles.So that hidden malfunction and safety issues can be found and avoided in time. Depending on computer communication technology, GPS（Global Position System）.technology and GPRS（General Packet Radio Service） technology, Vehicle coordination is carried out. Vehicle＇s on-line detected information is displayed and stored according to its position. Malfunction of vehicle＇s important parts can be alarmed in time combining with vehicle position where it happons.Vehicle＇s information and history data can also be inquired in the databsse.With .GPRS technology, data can be transmitted wirelessly to ground station and can be shared by others by connecting to the, ground station.The function of main parts and its actualizing are referred Besides these, the establishment of running-gear＇s malfunction model is discussed.Tbe, practicability and reliability of the monitoring system are proved by experiments on real run. The malfunction criterions of some parts can be improved by more experiment data to improve the whole system.
