PLC控制电梯选向电路程序的改进与应用

Research on PLC Control Elevator Direction Selection Circuit

电梯选向控制是关系到电梯启动、运行的重要控制环节,若选向控制电路设计不完善,考虑不周全,存在设计缺陷,就会影响电梯的正常运行,给乘客带来不必要的麻烦。针对电梯技术教科书中选向电路控制程序在实践教学中存在不合理运行,影响了使用效率,为此在实践教学中改进了程序,使其运行更加合理、可靠。

The elevator direction selection control is an important control step.If there exist problems in the design of control circuit,the passengers will be taken into dangerous situation.This paper makes a research and experiment on the problem of elevator＇s direction selection in the textbook of Elevator Technology,and puts forwards a solution to make it reasonable and reliable.
