Elevator door closing control system and control method

Abstract

The invention provides an elevator door closing control system and control method, and relates to the technical field of elevator control. The elevator door closing control system comprises multiple data collection devices used for collecting first data, within the first preset range, in an elevator door and collecting second data, within the second preset range, outside the elevator door, a controller and a portal crane control device; the controller is used for receiving first data and second data and judges whether a person exists in the first preset range and the second preset range or not, and moves in the direction of the elevator door with the speed larger than the preset speed; the portal crane control device is configured to control the elevator door to stop from closing and enable the elevator door to enter in the complete opening state again when it is judged that the person exists in the first preset range and the second preset range, and moves in the direction of the elevator door with the speed larger than the preset speed. According to the elevator door closing control system, the phenomenon that the person needs to enter in and go out of the elevator, and the elevator door is directly closed is avoided, great convenience is brought to the person entering in and out of the elevator door, and the phenomenon that the elevator is closed in advance, and the person entering in and out of the elevator is accidentally injured is avoided.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator door closing control system and control method. Background technique [0002] In the practical process of the elevator, in general, when the elevator reaches the corresponding floor, the elevator will be turned on and turned off after a preset time. And many times, there are many people in the elevator, and the time to go up and down is longer, and the elevator will still be closed after the preset time. Only when it can be detected that someone passes through the elevator door, the closing time of the elevator door will be delayed. And some people who want to get on the elevator or get off the elevator will go out late because they are standing in the back position or due to the large number of people. In many cases, the elevator door will be directly closed, which brings trouble to the people who take the elevator. If you move to the elevator door at a fas...

Problems solved by technology

In many cases, there are many people in the elevator, and the time for going up and down is long. The elevator will still close after the preset time. Only when someone can be detected at the elevator door, the closing time of the elevator door will be delayed.

And some people who want to get on the elevator or get off the elevator are late because they are standing in the back position or due to the large number of people. In many cases, the elevator door will be directly closed, which brings troubles to the people who take the elevator.

If you move faster to the elevator door at this time, because the sensor at the elevator door has a certain delay time, it is easy to be caught by the closing elevator door
