Automatic alarming device of people trapped lift car

Abstract

The invention relates to the technical field of elevators, and discloses an automatic alarming device of a people trapped lift car. The device comprises a lift car body, a processor, a relay, a humanbody inductor and a loudspeaker, wherein the outer wall of the human body inductor is fixedly connected with the inner wall of the lift car body, the top, far away from an inner display, of the loudspeaker is connected with the inner wall of the lift car body in a clamped mode, and one side, far away from the processor, of the relay is fixedly connected with the top of the lift car body. The automatic alarming device for the people trapped lift car has the advantages that an alarm signal is automatically sent out after an elevator stops running, a lift car door is kept in a closed state, illuminating lamp extinguishment, human body movement, abnormal sound and abnormal vibration are detected through the human body inductor, the signal can be directly connected with various existing alarm devices of the elevator, so that the trapped people does not need to operate any device actively, and the automatic alarm signals can be sent to a unit duty room, an elevator maintenance unit, an emergency rescue mechanism and the like.
