电梯门锁安全回路改进设计

The improved design of elevator door lock loop

电梯门锁安全回路对保障电梯运行的安全性非常重要。分析一起电梯门锁故障的原因,对原来门锁电路进行改进,用PLC控制方式控制门锁电路,通过程序判断门锁安全电路是否正常,当出现故障时,电梯只能检修运行,防止因门锁电路故障、操作人员疏忽大意而引起的事故,提高电梯运行的安全性。

The elevator door safety loop is very important to ensure the safety operation of the elevator. Cause analysis of elevator door fault,the original door lock circuit is improved,with the PLC control door lock circuit,through the procedure judgment door lock circuit is normal,when fault occurs,the elevator can only prevent maintenance operation,caused by the door lock circuit fault,operation personnel careless accidents,improve the safety of elevator running.
