Problems solved by technology

[0008] Therefore, none of the existing elevator door machine control methods can better solve the problem of the variation of landing door closing resistance, which may easily cause the elevator door opening and closing time to become longer or cause impact and noise problems during the closing process of the landing door.

Embodiment Construction

[0092] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0093] like figure 1 As shown, the elevator landing door control method provided by the present invention comprises the following steps:

[0094] Step 1, look up the table according to the current floor number, and calculate the speed resistance coefficient of the current floor, the specific steps are as follows:

[0095] (1) According to the current floor number F, check the corresponding table to get the value C of the floor door counter of the current floor n ;

[0096] (2) According to the value of the land...

Abstract

The invention discloses an elevator landing door control method. Current and speed values of a motor in every door opening and closing process are detected in real time, the kinetic friction force which is independently borne by a car door is estimated at the last stage of the previous door closing in place, the sum of the borne kinetic friction force of the car door and a landing door is estimated at the initial stage of door opening this time and the near end stage of door closing this time, so that the size of the kinetic friction force which is independently borne by the landing door afterthe landing door and the car door are disengaged is estimated, the theoretical disengagement speed of the landing door at the moment when the landing door and the car door are disengaged is calculated according to the kinetic friction force of the landing door, the theoretical disengagement speed of the landing doors in all the floors is corrected according to the state that whether the landing door is completely closed or not after the car door is closed, so that the landing door can be reliably and stably closed.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to a landing door control method in the field of elevator control. Background technique [0002] There are two different working stages in the closing process of the landing door of the elevator. In the first stage, when the landing door is far away from the door closing position, the door knife on the car door is inserted into the gate ball on the landing door, and the car door and landing door are driven by the door motor to link together; the second stage , when the landing door is about to close in place, the door knife on the car door is separated from the gate ball on the landing door. At this time, the driving force of the door motor is only applied to the car door. Closed together. The speed at which the landing door is about to lose the driving force of the door machine is called the release speed of the landing door. [0003] During the self-closing process of the landin...
