Electric door and window integrated electronic absolute value encoder and data processing method thereof

Abstract

The invention relates to the electric door and window control technology field and especially relates to an electric door and window integrated electronic absolute value encoder and a data processing method thereof. A magnet ring, a standby cell, an electronic absolute value encoder induction plate, an orthogonal optical encoder and magnetic induction switches are included. The electronic absolute value encoder induction plate passes through a motor rotating shaft and is fixedly connected to a motor end cap. The magnet ring is arranged between the electronic absolute value encoder induction plate and a raster sheet, passes through the motor rotating shaft and is fixedly connected to the raster sheet. The magnetic induction switches and the magnet ring are arranged oppositely. There are not less than three magnetic induction switches. A standby cell output terminal is electrically connected to the magnetic induction switches. The orthogonal optical encoder and the magnetic induction switches are integrally arranged on the motor rotating shaft. The orthogonal optical encoder drives a motor to rotate. Through the magnetic induction switches, an absolute position of a door is acquired so as to realize high precision control of the door. A condition that the orthogonal optical encoder is arranged externally so as to realize acquisition of a door position can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric door and window control, in particular to an electric door and window integrated electronic absolute value encoder device and a data processing method thereof. Background technique [0002] The existing electric door and window control system generally uses a frequency converter motor or a servo motor as the actuator, and an external absolute encoder is installed on the door reel, and the door is controlled by sensing the position signal of the external absolute encoder. When it is about to reach the door opening position, decelerate the actuator and stop locking to the door opening position; when it is almost reaching the door closing position, decelerate the actuator and stop locking to the door closing position. The precision and reliability of the external absolute encoder are directly related to the precision and stability of the control, and also play the role of limit and protection. [0...

AI Technical Summary

Problems solved by technology

The mechanical absolute value encoder saves the multi-turn information of the machine through the scale of the gear through multi-stage gear transmission. and consistency cannot be guaranteed, so the high-precision door and window control system is limited

The electronic absolute encoder can solve the accuracy problem caused by the positive and negative backlash by putting an additional permanent magnet on the transmission shaft, and then installing the magnetic sensor on the transmission shaft coaxially. The way of split installation is naturally subject to the above-mentioned shortcomings
