The invention discloses an elevator door lock fault early warning method, system and device and a storage medium, tail end electric signals of a door lock loop are collected when an elevator door is closed, the tail end electric signals are tail end voltage or tail end current, and the change rate of the tail end electric signals is calculated based on the tail end electric signals collected at multiple collection moments; whether the change rate is larger than a preset rate or not is judged, when the change rate is larger than the preset rate, a door lock fault early warning signal is sent, and fault early warning is conducted on faults, caused by oxidation, vulcanization, dust accumulation, abrasion and the like, of a door lock contact in advance according to the change rate of the tail end electric signal, so that the door lock is maintained; and the running stability and the transportation efficiency of the elevator are improved.

    本发明公开了一种电梯门锁故障预警方法、系统、设备及存储介质,在电梯门闭合时采集门锁回路的末端电信号,末端电信号为末端电压或末端电流,基于多个采集时刻采集的末端电信号,计算末端电信号的变化速率,判断变化速率是否大于预设速率,在变化速率大于预设速率时,发出门锁故障预警信号,通过末端电信号的变化速率,提前对门锁触点因氧化、硫化、积尘、磨损等原因导致的故障进行故障预警,以便对门锁进行维护,提高了电梯运行的稳定性和运输效率。
