摘　　要：电梯若在人为短接门锁回路的情况下运行,乘坐电梯的人员将面临严重的安全威胁,甚至造成剪切、坠落等事故;为了减少甚至避免该类事故的发生,电梯控制系统中引入了门回路检测。门回路主要通过多个门锁触点串联构成,若是有门锁触点无法导通,电梯将立即处于停止状态,为乘客安全提供了保护。这也突出了门回路检测功能的重要性。简要阐述了电梯门回路检测的功能及作用,分析了门回路检测的原理,重点介绍了检验中碰到的一个贯通门门回路检测电气图与现场接线不符的案例以及门回路检测功能检验注意事项,为进一步提高门回路的检验水平提供参考。If the elevator operates under the condition of artificially short circuiting the door lock circuit,the elevator passengers will face serious safety threats,and even cause accidents such as shearing and falling.In order to reduce or even avoid such accidents,door loop detection is introduced into elevator control system.The door circuit is mainly composed of multiple door lock contacts in series.If the door lock contacts cannot be connected,the elevator will immediately stop,providing protection for passenger safety,which also highlights the importance of the door loop detection function.The function of the lift door loop detection was briefly described,the principle of the door loop detection was analyzed,and a case of inspection through the door and door circuit was introduced,which was inconsistent with the on-site wiring and the inspection of the gate loop inspection function.It provides a reference for further improving the inspection of gate circuit.
