Elevator control system and method

Abstract

The embodiment of the invention provides an elevator control system and method. According to the elevator control system and method, a main control device can control the operation of a lift car according to the control information of an elevator, the control information of the elevator comprises the states of keys of all layers in the lift car, the state whether passengers exist in the lift car or not, the passenger fullness rate in the lift car and the state of key pressing in elevator halls; a first proximity switch array composed of L proximity switches is arranged at the bottom of the lift car so that a lift car monitoring controller can determine the passenger fullness rate in the lift car according to the statistical number of the proximity switches which receive reflection signalsand the statistical total number of the proximity switches, wherein the passenger fullness rate reflects the passenger carrying conditions in the lift car, therefore, after the main control device obtains the passenger fullness rate in the lift car, the main control device can update the control information of the elevator according to the passenger fullness rate to enable the control informationto be more accurate, the operation of the lift car is controlled according to the updated control information of the elevator, then invalid opening and closing of the elevator are avoided, resources are saved, and the service life of the elevator is prolonged.

Description

technical field [0001] The present application relates to the technical field of elevator control, in particular to an elevator control system and method. Background technique [0002] With the acceleration of urbanization, the number of high-rise buildings is increasing day by day. As an important part of high-rise buildings, elevators play an important role in people's daily life, bringing convenience and speed to people's travel. Conventional elevator operation rules are as follows: Passengers randomly arrive at the lobby and request the elevator group to respond by pressing the up / down button. When the specified elevator or other elevators arrive at the floor, the request will be eliminated in the request queue. When the elevator in the related art is running, the following situations of invalid scheduling often occur: [0003] (1) There is a call request when there is no load in the car. It mainly refers to that the passenger presses the desired floor, and the eleva...

AI Technical Summary

Problems solved by technology

It mainly refers to that the passenger presses the desired floor, and the elevator will respond to the instruction. However, when the passenger abandons the ride due to some reasons and leaves the elevator, the elevator in the related technology will still respond to the floor instruction pressed by the passenger, making the elevator empty. Load operation and invalid switch elevator door

[0004] (2) The car is fully loaded but there is a request from the elevator hall

[0005] Such ineffective scheduling causes unnecessary switching and running of the elevator, resulting in a waste of energy. Frequent opening of the elevator door and ineffective pressing of keys will not only lead to power consumption, but also shorten the service life of the elevator, leading to aging of relevant parts or Wear and tear, speeding up the damage of the elevator
