Elevator protection method, device and system

Abstract

The embodiment of the invention discloses an elevator protection method, device and system. The elevator protection method comprises the steps that an image, collected by detection equipment at a preset position in an elevator, in the elevator is obtained; the distance between an object in the elevator and the inner wall of a lift car of the elevator is determined based on the image; and a lamp strip arranged on the inner wall of the lift car is controlled to change the light emitting color according to a preset manner based on the distance, and distance reminding is conducted on a user through color changes of the lamp strip. According to the elevator protection method provided by the embodiment of the invention, the distance between the object and the inner wall of the lift car can be accurately judged, and therefore the situation that when the user cannot determine the distance between the object and the inner wall of the lift car easily, the lift car wall of the elevator is damagedis avoided, and elevator protection is achieved; and an anti-collision layer does not need to be arranged in the elevator to protect the lift car of the elevator, and therefore compared with a methodfor protecting the elevator through the arrangement of the anti-collision layer, the elevator protection method provided by the embodiment of the invention has better attractiveness and practicability.

Description

technical field [0001] The embodiments of the present invention relate to elevator technology, and in particular to an elevator protection method, device and system. Background technique [0002] At present, the demand for robots to ride elevators is also increasing. However, due to the narrow environment inside the car and the presence of car walls made of various materials such as glass, mirror, and stainless steel, the robot can use its own millimeter wave, laser radar, and camera in the car. Recognition sensors, etc., are easily affected and cause damage to the robot when it hits the car wall. [0003] For the car elevator, there is also the same problem. When the car enters the car, the radar of the car will be inaccurate due to the narrowness of the car, so it is difficult for the passengers to judge the distance between the car and the car wall.

Problems solved by technology

[0002] At present, the demand for robots to ride elevators is also increasing. However, due to the narrow environment inside the car and the presence of car walls made of various materials such as glass, mirror, and stainless steel, the robot can use its own millimeter wave, laser radar, and camera in the car. Recognition sensors, etc., are easily affected and cause damage to the robot when it hits the car wall

[0003] For car elevators, the same problem also exists. When the car enters the car, the narrowness of the car will make the radar of the car inaccurate in detection, so it is difficult for the passengers to judge the distance between the car and the car wall.

[0004] For freight elevators, since it is often necessary to carry large items, they are often covered by the goods during transportation, and it is difficult to determine the distance between the items and the car wall, so it is easy to cause the goods to be damaged or the car wall to be damaged.

[0005] It can be seen that there is a problem in the prior art that the elevator is damaged because the position of the object in the elevator cannot be accurately determined
