The invention discloses an elevator light curtain failure self-checking method and device. The elevator light curtain failure self-checking device comprises a light curtain infrared emitter and a light curtain infrared receiver, the light curtain infrared receiver is arranged at one end of the light curtain infrared emitter, one end of the light curtain infrared receiver is electrically connected with a car control end, and one end of the car control end is electrically connected with a detection and recognition device. According to the elevator light curtain failure self-checking method and device, when an elevator is in a stop state, an elevator door is in a closed state, first-time light curtain detection is carried out when the elevator is in the stopping state, it is ensured that under the condition that external factors are eliminated, whether a light curtain can be correctly recognized or not in the normal state can be detected, and frequent opening of the elevator door caused by light curtain faults is prevented; and when the elevator is in the stop state, the elevator is in the closed state, secondary light curtain detection is carried out when the elevator is in the stopping state, the situation that the fault state is intentionally manufactured under control of the car control end can be detected, and therefore whether the light curtain can be correctly recognized or not is judged, and the situation that people are clamped by the elevator due to light curtain faults is prevented.
本发明公开了一种电梯光幕失效自检方法及装置,包括光幕红外发出器和光幕红外接收器,所述光幕红外发出器一端设置有所述光幕红外接收器,所述光幕红外接收器一端电性连接有轿厢控制端,所述轿厢控制端一端电性连接有检测识别装置;本发明中在电梯处于停止状态,电梯门处于关闭状态,电梯处于停靠状态下进行首次光幕检测,确保排出外部因素,能够检测在正常状态下,光幕能否正确识别,防止光幕故障导致电梯门频繁开启,在电梯处于停止状态,电梯门处于关闭状态,电梯处于停靠状态下进行二次光幕检测,能够检测在轿厢控制端控制下,故意制造故障状态,从而判断光幕能否正确识别,防止光幕故障导致电梯夹人的情况发生。
