Embodiment 1

[0037] A method for controlling a car door drive motor by a door machine controller, such as figure 1 , figure 2 shown, including the following steps:

[0038] 1. When the door closing process starts on the first floor, the door machine controller controls the car door drive motor to start forward rotation according to the default car door position and speed curve of the floor, and the car door drive motor drives the car door to start to close; the default car door position and speed curve of this floor is the first i car door position speed curve, 1≤i≤N, j=i, N is a positive integer greater than 1;

[0039] Such as image 3 , respectively show the first car door position and speed curve, the second car door position and speed curve, and the third car door position and speed curve. The car door position and speed curve includes the car door fully open point, car door speed There are four positions: maintenance point, car door separation point and car door fully closed poin...

Embodiment 2

[0054] Based on the method for controlling the car door driving motor by the door machine controller in Embodiment 1, if a floor meets the set reset condition, the door machine controller restores the default car door position and speed curve of the floor to the first car door position and speed curve.

[0055] The setting reset condition of a floor can be that the reset key of this floor is triggered; it can be that the default car door position and speed curve of the floor is that the non-first car door position and speed curve exceeds the set time (for example, 24 hours); It can be that the car door closing torque after the car door speed maintenance point in the door closing process is less than the lower limit set torque, and the lower limit set torque is smaller than the upper limit set torque; or the car door drive motor works after the car door speed maintenance point in the door closing process The current is less than a certain percentage (eg 50%) of its rated curren...

Abstract

The invention discloses a control method of a door machine controller for a car door drive motor. In the elevator door closing process, whether the door closing state of an elevator door device is abnormal or not is detected; if the state is abnormal, the device enters in the specific control mode, the door machine controller controls the car door drive motor to increase the car door closing speedof a car door and landing door separation point, and therefore the running speed of a landing door in the final door closing state is increased; in the specific control mode, if the car door closingspeed of the car door and landing door separation point is increased, the landing door cannot be closed still, and the car door closing speed of the car door and landing door separation point is further improved to achieve landing door closing. According to the control method of the door machine controller for the car door drive motor, when the door closing state of the elevator door device door is abnormal due to external resistance, the elevator door device can be automatically controlled to be subject to normal door closing, the structure is simple, and a dedicated detection unit or extra auxiliary device is not needed.

Description

technical field [0001] The invention relates to elevator control technology, in particular to a method for controlling a car door drive motor by a door machine controller. Background technique [0002] The door equipment of the elevator includes the car door of the car and the hall doors installed on each floor of the building. The car includes a drive motor that drives the car door to provide driving force for the opening and closing of the car door. The hall door has a self-closing mechanism such as a weight device. [0003] The car door is an automatic door, including door knives, and the hall door is a driven door, including gate kicks. [0004] The process of opening the door is: after the car reaches the target floor, the door knife on the car door is inserted into the gate ball on the hall door to realize the linkage between the car door and the hall door. The car door and the hall door use the power of the car door drive motor to overcome the hall door. The resista...
