摘要
电梯是生产和生活中常见的运输工具.随着科技的发展,电梯已采用PLC进行控制.应用触发器指令设计的基于PLC的四层电梯控制系统的控制方案思路清晰、简单、方便,易于扩展至多层电梯控制.
The elevator is the common means of transport and is controlled with PLC. The application of trigger instruction makes the control scheme clear, simple, convenient, and easy to be expanded to the multi-layered elevator controls.
