基于PLC的交流转辙机试验控制台

摘要

通过分析铁路现场应用中转辙机的控制和表示电路，设计了基于PLC的简单、易用的转辙机控制台，该控制台可用于转辙机的维修、寿命试验等。%By analyzing the control and indicator circuits of point machines which are used in the railway on site , we designed a switch machine control station based on PLC. The control station can be used for maintenance and testing the life of point machine.
