庞大、昂贵的列车及其设备使轨道信号系统逻辑的实车验证成本高、实施难，而半实物模型仿真是降低成本的有效手段。鉴于此，提出了一种模型列车系统，以CC2530芯片为硬件核心，以Z-Stack 协议栈为软件构架，通过状态机实现应用层通信逻辑，模拟实车间的通信仿真。首先介绍了CC2530芯片及系统框架，再阐述了模型节点硬件及软件设计，并成功组建了由控制中心与列车节点构成的星形网络，实现了控制中心对列车节点的实时运行控制及列车节点对控制中心的信息反馈。实验结果表明，基于 ZigBee 的轨道列车模型系统可用于信号系统逻辑验证。

To reduce the difficulty of the real train test, and insure the logic of railway signal system, hardware-in-the-loop simulation is an effective way. In this background, a design scheme of the wireless railway signal simulation system based on embedding CC2530 chip, Z-Stack and FSM application logic into model trains is presented. In this context, the reason of choosing CC2530 and the structure of the system are introduced; then, the hard and software design are discussed in detail. Experiment results show that the train model based on ZigBee can be used to insure the logic of railway signal system.
