The invention discloses a monitoring device and circuit for verifying the circuit state of a main door lock of an elevator landing door, the monitoring device comprises a photoelectric switch, a car door independent monitoring switch and a mainboard, the photoelectric switch and the car door independent monitoring switch are fixedly connected with a car door head, and a light isolation plate for triggering the photoelectric switch to act is fixedly connected with a door machine synchronous belt. The invention relates to the technical field of elevator landing door main door lock circuit state detection, in particular to a monitoring device and circuit for verifying the elevator landing door main door lock circuit state, which are characterized in that a photoelectric switch is additionally arranged at a proper position of a car door head, and the photoelectric switch is electrically connected with an elevator mainboard. Compared with an existing door loop monitoring device and circuit, only one photoelectric switch is added, one detection step is added, the door loop detection function can independently detect whether the electrical contact of the main door lock of the elevator landing door is short-circuited or not, and the accident that people fall into a shaft possibly due to the fact that the main door lock is not locked can be prevented.
本发明公开了一种验证电梯层门主门锁电路状态的监控装置及电路,包括光电开关、轿门独立监控开关以及主板,所述光电开关、轿门轿门独立监控开关分别与轿门门头固定连接,触发所述光电开关动作的隔光板与门机同步带固定连接。本发明涉及电梯层门主门锁电路状态检测技术领域,该验证电梯层门主门锁电路状态的监控装置及电路,通过在轿门门头的合适位置增加一个光电开关,并且将这个光电开关与电梯主板电连接。与现有门回路监控装置及电路相比,本发明仅多了一个光电开关,多了一次检测步骤,使门回路检测功能能够单独检测电梯层门主门锁的电气触点是否被短接,可防止主门锁未锁紧可能造成的人员坠落井道事故。
