Control method of door closing resistance self-adaptive elevator door motor

Abstract

The invention provides a control method of a door closing resistance self-adaptive elevator door motor. The control method of the door closing resistance self-adaptive elevator door motor comprises the following steps of: S1, judging whether no passenger or no foreign matter exists in an elevator door closing stroke or not in real time, and if so, performing S2; if not, performing S4; S2, obtaining capacitance between elevator doors on the two sides through a capacitance sensor, calculating the movement speed between the elevator doors on the two sides, judging whether the door closing resistance is larger than a threshold value or not according to the movement speed, if yes, executing a step S3, and if not, executing the step S4; S3, enabling a door motor controller to reduce the operation speed of a door motor to a first speed V1 and increase the door closing torque until the doors are closed; and S4, enabling the door machine controller to control the door machine to operate at the normal speed V0 and control the door closing moment to be the normal door closing moment until the doors are closed. According to the control method of the door closing resistance self-adaptive elevator door motor provided by the invention, the actual closing speed of the elevator doors is monitored in real time, the actual closing speed of the elevator doors is used as a condition for judging whether the closing resistance of the elevator doors is too large or not, and the reliability is high aiming at all factors except the air outlet force.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a control method for an adaptive elevator door machine with door-closing resistance. Background technique [0002] With the development of society and the advancement of science and technology, elevators play an increasingly important role in people's lives. Passengers have higher requirements for elevator reliability. In the elevator industry, it is well known that elevator doors The fault in the area is the highest, so the reliability requirements of the elevator in the process of opening and closing the door are very important. [0003] With reference to the control method and system of the elevator door machine whose Chinese patent authorization announcement number is CN105645237B, the ambient wind force of the elevator door machine is detected, and the environmental wind force is output to the door machine control system; Converted to analog quantity A; when the door mach...

Problems solved by technology

[0004] The invention solves the problem in the prior art that the door operator is only regulated according to the wind force of the environment, and the reliability is not high, and proposes a control method for the door operator of an adaptive elevator door closing resistance, which uses real-time monitoring of the actual closing speed of the elevator door, and uses the The actual closing speed is used as a condition to judge whether the closing resistance of the elevator door is too large, and it is reliable for all factors except the wind force.
