Elevator door motor control system and elevator door motor control method

Abstract

An elevator door motor control system and an elevator door motor control method control opening and closing of an elevator door by controlling running of an elevator door motor. The elevator door motor control method includes the steps: setting initial parameters, detecting a running door width A of an elevator, detecting a residual door width B, and according to the set initial parameters, the detected running door width A and the detected residual door width B, controlling the elevator door motor to open or close the elevator door according to a door opening speed curve or a door closing speed curve after a door opening command or a door closing command is received. The elevator door motor control method has the advantages that by optimizing the door opening and door closing speed curves, the method enables the elevator door to be proper in speed when the elevator door is opened and closed, and speed is low in starting and ending stages while speed in an intermediate stage is high, so that door opening and closing efficiency is improved, and comfort level is good during opening and closing of the elevator door.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator door machine control system and method for controlling the opening and closing of elevator doors through the elevator door machine. Background technique [0002] The elevator door is the passage for passengers or goods to enter and exit the elevator car. Generally, the operating speed and time of the elevator door machine are controlled by the elevator door machine control system to realize the switch control of the elevator door. The elevator door machine control system will also be connected with the elevator door machine through the encoder. Through the encoder, the elevator door machine control system can obtain the rotation angle of the elevator door machine, and can obtain the moving distance of the elevator door driven by the elevator door machine through calculation. In addition, the elevator door machine control system generally also detects the current flowi...

AI Technical Summary

Problems solved by technology

[0003] However, when the commonly used elevator door machine control system controls the opening and closing of the elevator door by controlling the elevator door machine, the running speed of the elevator door is poorly optimized, or the door opening comfort is poor.

For example, the speed of opening and closing the door is always fast, or the overall speed of opening and closing the door is slow and the efficiency is low
