Abstract

The invention discloses a method for controlling elevator landing doors. Through real-time detection of the current and speed values ​​of the motor during each door opening and closing process, the dynamic friction force borne by the car door alone is estimated at the last stage of the previous door closing, and the door is opened this time. Estimate the sum of the dynamic friction force of the car door and landing door at the initial stage and the end stage of this door closing, so as to estimate the dynamic friction force of the landing door alone after the landing door and car door are separated, and calculate according to the dynamic friction force of the landing door The theoretical disengagement speed of the landing doors at the moment when the landing doors and car doors leave, and correct the theoretical disengagement speeds of the landing doors of all floors according to whether the landing doors are completely closed after the car doors are closed, so as to ensure that the landing doors are closed reliably and smoothly.

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...
