The invention discloses an elevator pit maintenance reset system which comprises a pit maintenance plate, a main control unit and an external call control panel, the pit maintenance plate is used for marking the pit maintenance state and outputting the marked state to the main control unit, the pit maintenance plate is provided with a pit maintenance switch, and the pit maintenance switch is operated to enter the pit maintenance state; the external calling control panel is provided with a bottom layer external calling key at a bottom layer elevator hall; and if the main control unit detects a reset signal of the pit maintenance switch, a door lock conduction signal of a bottom layer and a trigger signal of a bottom layer external calling key, a safety circuit of the elevator is controlled to reset correspondingly so as to eliminate the influence of pit maintenance on external calling of the elevator. According to the elevator pit overhauling and resetting system provided by the invention, the safety during pit overhauling is improved, the convenience during resetting after overhauling is improved, and the improvement cost of an existing elevator overhauling system is low.
本发明公开了一种电梯底坑检修复位系统,包括底坑检修板、主控单元和外招控制板,底坑检修板用于标记底坑检修状态并将标记的状态输出至主控单元,底坑检修板设有底坑检修开关,通过操作底坑检修开关以进入底坑检修状态;外招控制板在底层电梯门厅处设有底层外招按键;若主控单元检测到底坑检修开关的复位信号、底层的门锁导通信号以及底层外招按键的触发信号,则控制电梯的安全回路相应复位以消除因为底坑检修对电梯外招的影响。本发明提供的电梯底坑检修复位系统提高了底坑检修时的安全性,提高了完成检修后复位时便捷性,对现有电梯检修系统改造成本低。
