摘　　要：针对现阶段铁路系统广泛采用的转辙机参数测试台普遍存在的重量大、移动困难、无法对转辙机进行在轨检修的现状,设计出一种基于小型PLC控制系统的便携式转辙机测试仪,精确测量转辙机转换力以及工作电流,并将基于WLAN技术的无线通信方式运用到PLC控制系统中,通过搭建小范围无线局域网,使接入此无线网络的手机、PDA等移动智能终端实现对测试仪所测数据的采集和记录。现场测试结果表明,该仪器运行稳定可靠、使用方便、测量准确,完全满足现场对转辙机实时在轨检测的需求。For the present situation of the point machine testers used by railway system have disadvantages such as heavy weight and moving difficulty,and it＇s impossible to use it on orbit maintenance,this paper designed a point machine tester based on small PLC control system,which can test the switching power and working current of point machines accurately,and the wireless communication technology based on WLAN had been used to the system. Through the small range of wireless local area network,smart mobile phones and other PDAs can collect and record the date from point machine testers. Through field testing,the instrument is stable and reliable operation to meet the demand of real-time and on orbit detection for switch machine.
