摘　　要：现代有轨电车具有无污染、速度较快、运量较大、建设成本低等优点,在城市发展中占有重要的地位,是未来城市轨道交通发展的重要方向。介绍了现代有轨电车信号系统轨旁控制器中的一个关键核心控制模块,采用模块化电子电路取代由安全型继电器构成的单相交流转辙机控制表示电路。详细论述单相交流转辙机控制模块的模块化硬件架构,以及驱动电路、表示采集电路的设计及分析过程。最后,提出软件设计方案,采用流程图对嵌入式软件的原理进行说明和描述,实现了单相交流转辙机控制模块对道岔位置的控制。Abstract： Modem tram plays an important role in the development of urban rail transit with the features of non-pollution, faster speed, more carrying capacity and lower construction cost, and is an important trend of future urban rail transit. We introduce one core control module of track side controller of modem tram signal system, which uses modularized electronic circuits to replace the control circuits of single- phase AC switches consisting of safety relays. The modular hardware structure of the control module of single-phase AC switches was discussed in detail together with the design and analysis process of the driv- ing circuit and signal acquisition circuit. Finally, the scheme of system software is proposed and the prin- ciple of embedded software was described using flow chart. The software can enable the control module of single-phase AC switches to control switch position .
