一种电梯偶发性开关故障的实时诊断与处理方法
|
摘要
电梯偶发性故障时有发生,为人们生活的安全带来极大隐患。本文针对电梯偶发性开关故障提出了一种实时诊断和处理方法。负载、运动相对稳定部分选择时间原则实时诊断,负载变化、运动路线易变化的轿厢部分选择距离原则故障诊断,处理程序可嵌入已有电梯控制程序中。
Accidental elevator failures happen occasionally which bring great risk for people's safety. A real-time diagnosis and handling method for accidental elevator switch failure is proposed. Time principle is selected for the real-time diagnosis of relatively stable load and movement part. The elevator car, where the load and running route changes chooses distance principle for failure diagnosis. The handling program can be embedded in the existing elevator control program.
