Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator car equipment, in particular to an elevator car based on AI intelligent control. BACKGROUND

[0002] The car generally includes a car frame and a car body, wherein the car frame is the load-bearing structure of the car, and the load (self weight and load) of the car is transmitted to the traction steel wire rope by it, and when the safety clamp acts or the squat bottom buffer hits, the reaction force generated thereby is also borne, so the car frame must have sufficient strength. And the car body is a closed wall that forms a car space, in addition, the car is generally also provided with a control box (in-car control device), ventilation device, lighting, emergency lighting in case of power failure, alarm and communication device. At the same time, in order to prevent overload, a plurality of micro switches (contacts) or weight sensors are generally installed on the bottom beam at the bottom of the car, when the live car placed on the elastic rubber pad is displaced downward due to the increase of load, the micro switch is triggered to send a signal, or the sensor sends a continuous signal corresponding to the load, and when the load is overloaded (such as 10% of the rated load), the micro switch acts to make the elevator door unable to close and the elevator unable to start, and at the same time, a sound and light signal (some without light signal) is sent, so as to carry out overload control.

[0003] However, such a conventional elevator, on the one hand, cannot realize intelligent voice control, and on the other hand, due to the elasticity of the steel wire rope and the long length of the steel wire rope, when the car is running, especially when people enter the elevator at the moment, the steel wire rope often changes in elasticity due to the large instantaneous force, causing the car to have a sinking feeling, and due to the elastic effect of the steel wire rope, this sinking feeling is often a reciprocating up and down slight shaking, which causes dizziness or a feeling of fear at the moment of entering the elevator, affecting the comfort of the passengers. In addition, when the goods in the elevator are placed unevenly or the position of the person standing is unbalanced (the weight of the person is greatly different), the elevator car will tilt slightly, although the tilt is very small, but when the elevator is running, due to the large traction force, it will cause great wear and tear or uneven stress on the steel wire rope and the car, which will affect the service life of the elevator and the safety of the elevator operation.

[0004] With the continuous development of AI intelligent control technology, how to combine AI control with the car is one of the key means for people to realize intelligent control and comfortable control of the car.
