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

Abstract

The invention discloses an elevator, computer equipment, a readable storage medium and a method for controlling a car to stop. The method for controlling the car to stop comprises the following stepsthat car operation speed information and car position information are acquired; a first braking distance is calculated according to the car operation speed information in combination with the deceleration information of a brake; a safe distance is calculated according to the car position information; when the first braking distance is smaller than the safe distance, a brake braking instruction issent; and when the first braking distance is larger than the safe distance, an electric safety tongs braking instruction is sent. According to the elevator, the computer equipment, the readable storage medium and the method for controlling the car to stop, the operation safety of the car can be further improved, a bumper can be optionally omitted under the condition of guaranteeing safety operation of the car, and then the mounting cost and operation cost of the elevator can be reduced.

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
