摘　　要：主令及凸轮控制器作为传统的低压电器在起重运输机械中有广泛的应用,但由于其结构复杂,接触传动部件多,给维修带来许多困难。本文介绍在采用可编程控制器为主控设备的桥式起重机中,采用简单操作机构配合PLC软件实现传统主令及凸轮控制器功能的虚拟设备设计方法。As traditional low-voltage electrical apparatus, the pilot controller and the cam controller have been widely used in crane conveyance machineries. Because the structure is too complicated, it is very difficult to maintain. A virtual-equipment design method, that is, how to use simple operational machine together with PLC software to realize the traditional function of pilot controller and cam controller in the overhead crane is discussed in the paper.
