Abstract
The utility model relates to an abnormal behavior monitoring device in an elevator car, and belongs to the technical field of elevator monitoring. The device comprises a mounting seat which is fixed in an elevator car, and a cavity is formed in the mounting seat; a magnet is connected into the cavity through a second elastic piece, a closing coil is further arranged in the cavity, and when the elevator car descends in an accelerated mode, the magnet penetrates through the closing coil. The input end of the controller is connected with a current sensor through a comparator, the current sensor is connected with the closed coil, and the output end of the controller is connected with a backstop; and the camera is fixed on the mounting seat. The comparator compares whether the current flowing into the current sensor is larger than the initial value or not, and when the current is larger than the initial value, it is indicated that the elevator car is moving in an accelerated mode, so that the controller controls the backstop to work, the elevator car is braked emergently, and losses are reduced.
