Elevator, computer equipment, readable storage medium and method for controlling car stop

Abstract

The invention discloses an elevator, computer equipment, a readable storage medium and a method for controlling the stop of the car. The method for controlling the stop of the car comprises the following steps: obtaining information on the running speed of the car and information on the position of the car; The running speed information, combined with the deceleration information of the brake, calculates the first braking distance; according to the car position information, calculates the safety distance; when the first braking distance is less than the safety distance, the brake braking command is sent; when the second Once the braking distance is greater than the safety distance, an electric safety gear braking command is sent. The elevator, the computer equipment, the readable storage medium and the method for controlling the stop of the car can further improve the safety of the car operation, and can choose to cancel the buffer under the condition of ensuring the safe operation of the car, which is beneficial to reduce Elevator installation and operating costs.

Description

technical field [0001] The invention relates to the technical field of lifting, in particular to an elevator, computer equipment, a readable storage medium and a method for controlling the car to stop. Background technique [0002] The elevator implements top and bottom protection for the car through the three major safety components such as the speed limiter, mechanical safety gear, and buffer, so as to protect the equipment from serious damage and the personal safety of passengers. [0003] During the operation of the traditional car, the mechanical safety gear can only be activated after the limiter is activated. However, when the wire rope breaks or the traction condition is lost, the brake of the main engine cannot decelerate the car by holding the traction sheave tightly, and when the speed does not trigger the limiter, the electric safety gear cannot operate and can only rely on the buffer for protection . [0004] The setting of the buffer requires a larger pit dep...

AI Technical Summary

Problems solved by technology

However, when the wire rope breaks or the traction condition is lost, the brake of the main engine cannot decelerate the car by holding the traction sheave tightly, and when the speed does not trigger the limiter, the electric safety gear cannot operate and can only rely on the buffer for protection

[0004] The setting of the buffer requires a larger pit depth, resulting in higher installation costs

In addition, the buffer must be maintained in a timely manner, increasing maintenance costs
