Abstract

The invention provides a door machine system based on double linear motors and a synchronous motion control method thereof. The door machine system includes left and right linear motors, left and right door panels, position sensors and control systems. The invention adopts the left and right linear motors to directly drive the left and right door panels of the door operator to open and close respectively, and has the advantages of simple transmission structure, high efficiency, high precision, high reliability, space saving and convenient maintenance. Further, in terms of motion control, the present invention also adds a synchronous controller on the basis that the existing dual motors are independently controlled by their respective controllers, and uses the synchronous position error signal of the dual linear motors as the input of the synchronous controller, and then The output signal is sent to the main channel of the double linear motor for adjustment, so as to ensure the synchronous operation of the double linear motor and improve the anti-interference ability.

Description

technical field [0001] The invention relates to an elevator door machine, in particular to a door machine system based on double linear motors and a synchronous motion control method thereof, belonging to the technical field of door machine systems and motor control. Background technique [0002] The existing elevator door machine system consists of two parts, the car door and the landing door, wherein the car door device is active to open and close the door, while the landing door device is passive to open and close the door; the car door device is equipped with a door knife mechanism, and the landing door device Corresponding position is installed with gate ball. When the elevator is about to open the door, the motor first drives the door knife mechanism to hold the gate ball, thereby driving the floor door to move together; when the elevator closes the door in place, the motor drives the door knife mechanism to move in the opposite direction to release the gate ball, so t...
