摘　　要：根据6502电气集中道岔执行组电路工作原理,研究了一种基于AVR微处理器的五线制道岔控制电路测试系统。介绍了该系统的设计原理及思路,详细分析了各个功能模块的硬件架构,并绘制了软件的流程图。测试结果表明,它能够模拟三相交流转辙机(如S700K、ZDJ9)的动作过程,对五线制室内道岔控制电路进行智能化测试。系统结构简单,使用轻巧、方便,并带有微机控制的智能分析显示模块,能够实时地监测室内表示电路电压和动作电压、智能分析五线制道岔控制电路的故障。According to the principle of switch control circuit in the 6502 electric interlocking sys tem, we study an AVR-based testing system for five-wire switch control circuit. The design prin ciples and concept of the system are introduced, a detailed analysis of the architecture of each module is made, and a flow chart of the software is also given. Test results show that it can simu- late the course of action of the three-phase AC switch machine, such as ST00k or ZDJ9. And in- telligent tests have been carried out on the indoor switch control circuit. The system is simple in structure, portable and easy to use and equipped with intelligent analysis and display module con- trolled by computer so that the system can monitor the voltage of indoor indication circuit and acting voltage in a real-time manner and analyze the faults of five wire switch control circuit intel ligently.
