Problems solved by technology

However, if the car door is not closed at this time, it is prone to shearing accidents.
[0004] Currently, after a shearing accident, it is often necessary to wait for rescuers to come to free the trapped passengers, however, while waiting, the injuries of the passengers may worsen, resulting in serious injuries

Abstract

The invention discloses an elevator car shearing accident rescue method, device and equipment and a storage medium. When a traction motor stalling alarm signal sent by an elevator main controller is received, the position of an elevator car and the opening and closing state of an elevator door are determined, and whether a shearing accident occurs or not is judged according to the position of the elevator car and the opening and closing state of the elevator door. When the shearing accident occurs, an emergency rescue switch in a lift car is controlled to pop up, a shearing accident alarm signal is sent to the elevator main controller, and the elevator main controller shields external calling of all floors according to the shearing accident alarm signal. Under the condition that the control logic of an original elevator system is not changed, the system stability is improved, when it is determined that the shearing accident occurs, the emergency rescue switch in the lift car is controlled to pop up, so that trapped passengers or passengers in a same elevator can rescue themselves in time, the situation that the injury is aggravated due to long-time rescue waiting is avoided, and the safety is improved.

Description

Technical field [0001] Embodiments of the present invention relate to elevator technology, and more particularly to an elevator car shear accident rescue method, apparatus, device, and storage medium. Background technique [0002] With the continuous development of urbanization, the number of elevators is increasing, the elevator aging and the live maintenance, the elevator hidden danger, most of the cut accidents caused by accidents during the door. [0003] The elevator car has a large risk zone from the flat layer to the next running command, and we call it an unexpectedly move risk interval. In this section, the control system does not control the elevator, and the elevator is stable depending on the effectiveness of the safety device. If there is a problem in the safety device, the car may accidentally move, and before the car is accidentally moved to the security device action, if the car door is closed, at least the personnel do not appear clips. However, if the car door i...
