Description

TECHNICAL FIELD

[0002] Elevator is a vertical lift powered by motor, used to transport people and goods between different floors of building. It is usually composed of car, counterweight, traction machine, guide rail, control system and other main components. The car is the carrying space of passengers or goods, and the steel wire rope is driven by the traction machine to move up and down on the guide rail. The counterweight plays a role in balancing the weight of the car to reduce energy consumption. The control system is responsible for realizing various functions of the elevator, such as floor selection, speed control, safety protection, etc. The elevator greatly improves the efficiency of people going up and down in high-rise buildings, and is an indispensable important equipment in modern buildings.

[0003] In the context of continuous social development, high-rise buildings are everywhere, and elevators have become a standard configuration of modern buildings, widely serving people's daily travel. During the installation of the elevator, a certain gap will inevitably be left between the elevator doors. However, the size of this gap must be strictly controlled, as a gap that is too large will create serious safety hazards such as pinching and falling objects. Under the traditional mode of operation, workers often use a ruler to measure the gap between the elevator doors. However, this method has many drawbacks. On the one hand, the ruler reading requires close operation by the worker, and in the complex installation environment of the elevator, the reading process is extremely inconvenient. On the other hand, manual measurement with a ruler is easily influenced by human factors, resulting in a large deviation in the measurement result and making it difficult to accurately determine whether the gap is compliant.
