摘要
为提高电梯的运行效率及实现电梯的集中控制,两台电梯通常采用并联控制;在电梯全集选控制的基础上,分析了双梯并联调度原则,并详细介绍了基于S7-200双梯并联控制系统的设计方法;通过两台PLC通讯构成的双梯并联控制系统,不仅节省了硬件资源,而且大大降低了系统能耗。
In Order to improve the effiency oftwo elevators and realiZe the concentrated control two elevators are usually controlled in parallel Based on the conective selective control function of elevators, The Parallel-Elevator scheduling principle is introduced. The realization of the function of the parallelsystembased on S7-200was discussedin detail Usingthe method ofPLC constitutes double parallel PLC system not only saved the hardware re. sources,butalso greatly reducedthesystemenergyconsumption
