摘　　要：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。It was introduced the structure and the principles of Dispatching System for railway collection and distribution platform, discussed the GPS base stations, the mobile terminals and the achievement of the hardware and software components. Using the differential GPS technology to satisfy the request of Precise Positioning in real-time dispatching at the railsway collection and distribution platform. Using the module of CDMA implemented the data and the control information real-time transmitina through the Internet among the GPS datum station the monitoring center and the train mobile termination. The monitoring center based on the Precise Positioning of the train mobile termination implemented the electronic map demonstration in the direction speed, real-time control, coordinated dispatch and so on.
