Door machine self-learning method and apparatus

Abstract

The embodiment of the invention provides a door machine self-learning method and apparatus. The method includes a control module, a detection module, a judgement module and a processing module, wherein the control module is used for sequentially executing control instructions, corresponding to the motor door opening or closing sequence in a preset self-learning process, in a preset control instruction list so as to control the motor in an elevator door machine system to start rotating; the detection module is used for starting an encoder to carry out pulse detection while the motor rotates; the judgment module is used for carrying out detection through a position detection switch when the pulse detected by the encoder within the preset time does not change, so that the judgement module canjudge whether the current and actual direction of opening or closing a door both coincide with the current motor corresponding to the motor door opening or closing sequence or not; and the processingmodule is used for determining that the door machine succeeds in self learning when the judgment result is yes. Because the position detection switch is arranged, self learning is carried out in themanner of judging whether the running direction of the motor coincides with the actual door opening or closing direction, and it is guaranteed that the parameters of the elevator door machine are setcorrectly.

Description

technical field [0001] The invention relates to the field of elevator door machine self-learning, in particular to a door machine self-learning method and equipment Background technique [0002] In the prior art, in the field of elevators, the coded door operator needs to carry out self-learning, and the success of self-learning generally needs to include two processes: first closing the door and then opening the door. To succeed in self-learning, these two processes are required. In this case, the running direction of the motor is consistent with the direction of opening and closing the door. [0003] In the current elevator system, the door operator usually pre-sets the direction of the motor through parameters. Due to the difference in the winding method of the motor and the difference between the front and rear doors of the door operator, the running direction of the motor is different from the actual needs, resulting in the need for practical applications. The phenomen...

[0003] In the current elevator system, the door operator usually pre-sets the direction of the motor through parameters. Due to the difference in the winding method of the motor and the difference between the front and rear doors of the door operator, the running direction of the motor is different from the actual needs, resulting in the need for practical applications. The phenomenon that the user changes the parameters according to the actual application requirements, once the setting is wrong, the door machine cannot run normally
