The invention discloses a safety monitoring device and a safety monitoring method for an electric brake release device of an elevator. Detecting the input condition of commercial power; when it is determined that the mains supply is cut off, the lithium battery is switched for power supply, and the standby power supply is turned on for powering on the elevator mainboard; the brake release data packet is sent to an elevator mainboard according to a preset period; acquiring an input signal when the inching button is operated, and controlling the electric brake release device to release the brake; a door lock signal input by the elevator mainboard is obtained, and brake release starting information is sent to the elevator mainboard according to the door lock signal; receiving response information fed back by the elevator mainboard, wherein the response information is elevator speed information; according to the elevator speed information, it is determined that the elevator speed is not larger than a preset value, and the abnormal condition of brake loosening is detected through the signal points; and after it is determined that brake release is not abnormal, when a leveling signal is obtained, high voltage is stopped from being output to a band-type brake coil, and brake release stop information is sent to the elevator mainboard.

    本发明公开了一种电梯电动松闸装置的安全监测装置及安全监测方法。检测市电的输入情况;确定市电断开时,切换锂电池进行供电,并打开备用电源供电梯主板上电;按预设周期将松闸数据包发送至电梯主板;获取点动按钮被操作时的输入信号,控制电动松闸装置进行松闸;获取电梯主板输入的门锁信号,根据门锁信号将松闸启动信息发送至电梯主板;接收电梯主板反馈的响应信息,响应信息为电梯速度信息;根据电梯速度信息,确定电梯速度不大于预设值,通过信号点检测松闸的异常情况;当确定松闸无异常后,当获取平层信号时,停止输出高压至抱闸线圈,并将松闸停止信息发送至所述电梯主板。
