The invention discloses an active elevator driving device which is characterized in that the active elevator driving device comprises an elevator main control board, an elevator driving board and a frequency converter driving module, the elevator driving device can detect the instruction state of an upper computer, and when it is found that the upper computer requests an elevator to stop but the elevator still moves, the elevator driving device is actively started; and the speed of the elevator is quickly reduced. The safety accident caused by high-speed top rushing of the elevator when the elevator brake fails is prevented; abrasion to a band-type brake shoe, an elevator main steel wire rope and a traction wheel when the elevator stops suddenly can be relieved.
本发明公开了一种主动式电梯驱动装置,其特征在于,包括:电梯主控板、电梯驱动板和变频器驱动模块,电梯驱动装置能检测上位机指令状态,在发现上位机已要求电梯停止,但电梯却仍在移动时,电梯驱动装置主动启动,快速将电梯速度降下来。本发明防止电梯抱闸失效时,电梯高速冲顶产生安全事故;可减轻电梯急停时对抱闸闸瓦、电梯主钢丝绳及曳引轮的磨损。
