介绍基于GPS的铁路集散站台火车调度系统结构和组成原理,探讨GPS基准站、移动终端的软硬件组成和实现。采用差分GPS技术满足铁路集散站台货车的实时调度对货车精确定位的要求。在GPS基准站与列车移动终端、监控中心与列车移动终端间利用CDMA模块通过Internet网络实现数据与控制信息的实时传输,监控中心基于列车移动终端的精确定位实现对移动终端的方向速度电子地图显示、实时控制、整体的协调调度等功能。
This paper introduces the structure and composition principle of train dispatching system based on GPS, and discusses the hardware and software composition and implementation of GPS base station and mobile terminal. Using Differential GPS Technology to Meet the Requirements of Real-time Dispatching and Dispatching of Wagons on Wagons. Real-time transmission of data and control information between GPS base station and train mobile terminal, monitoring center and train mobile terminal by using CDMA module through Internet network. Monitoring center realizes electronic map display of directional speed of mobile terminal based on precise positioning of train mobile terminal , Real-time control, the overall coordination of scheduling and other functions.
