介绍了一种无轨载物列车组的自动行走控制系统,它是以S7-1200系列PLC作为核心控制器。首先介绍了列车的总体控制方案,了解列车主要实现的功能和PLC控制系统的组成,完成了PLC的模块选型及其外部接线图,然后采用PLC进行软件编程设计,实现列车组的行走控制。
An automatic walking control system for a rail-less train is introduced, which is based on S7-1200 series PLC as the core controller. First of all, it introduces the overall control plan of the train, understand the main function of the train and the composition of the PLC control system, completes the PLC module selection and its external wiring diagram, and then uses PLC to carry on the software programming design, realizes the train group walk control.
