车车通信后备模式下智能轨旁对象控制器系统

Smart Trackside Object Controller System under Vehicle-to-vehicle Communication Backup Mode

为解决基于车车通信的列车运行控制系统在通信中断情况下,信号系统降级后备模式运行的问题,设计了一种基于超带宽通信技术和射频识别技术的智能轨旁对象控制器系统,实现了双向列车定位、列车车号识别、列车完整性判断、列车行驶方向判断和轨道占用检测等一系列基础功能。研制了样机并进行实验室测试。测试结果表明,后备模式下,所提智能轨旁对象控制器系统可以提供地面设备办理进路的后备模式,保障行车安全。

In order to solve the problem of degraded backup mode operation of signaling system in case of the communication interruption of vehicle-to-vehicle communication based train control system,an intelligent trackside object controller system based on ultra-wide band communication(UWB)technology and radio frequency identification(RFID)technology is designed,which realizes a series of basic functions such as two-way train positioning,train number identification,train integrity judgment,train direction judgment and track occupation detection.The prototype is developed and tested in laboratory.Results show that under backup mode,the mentioned smart trackside object controller system can provide backup mode of ground equipment managing entry and ensure safe driving.
