摘　　要：采用可编程逻辑控制器或工控机实现列车模型控制系统功能的方案,存在成本高和通用性差等缺点,因此,针对城市轨道交通运营安全模拟沙盘,提出了利用PIC(可编程逻辑控制器)单片机开发分布式列车模型控制系统的设计方案。首先介绍了列车模型控制系统的基本原理和构架,然后详述了电脑接口板、调制解调板、区间编码板、信号灯和道岔解码板等关键硬件的设计。最后,在测试环境和沙盘中进行了控制系统功能验证。结果表明,所开发的列车模型控制系统具备列车定位与控制、信号灯与道岔控制、应急救援控制等功能,满足了城市轨道交通运营安全模拟沙盘列车模型控制系统的需求。Higher cost and poor universality defects exist in train model control system which uses PLC （programmable logic controller） or industrial computer. Therefore, a distributed control system based on PIC microcontroller is put forward for the safe operation of urban rail transit based on simulation sand table. Firstly, the basic principle and structure of the train model control system is introduced; secondly, the critical hard- ware design of the computer interface board, modulation and demodulation board, range encoding board, signal lamp and turnout decode board is described. Finally, the functions of the control system are verified on the sand table and environment tests. Testing results show that the developed control system will have functions of train control and position detecting, signal lamp and turnout control, emergence rescue control and others, and could meet the control requirements of urban rail transit simulation sand table.
