A reluctance type magnetic screw automatic door system and its positioning method

Abstract

The invention discloses an automatic door system with a magnetoresistance type magnetic screw and a positioning method thereof. The system comprises a suspension door plate, a control mechanism, an actuating mechanism, a sliding guide rail and limiting mechanisms, wherein the actuating mechanism comprises a magnetic screw; the magnetic screw is used for converting rotation motion into linear motion; the suspension door plate is fixedly connected with the magnetic screw; the control mechanism is used for controlling the actuating mechanism to drive the suspension door plate to do linear reciprocating motion along the sliding guide rail; the limiting mechanisms are located at two ends of the sliding guide rail and are used for limiting linear motion displacement of the suspension door plate;a rotating motor adopts an iterative learning control mode, so that the positioning accuracy and the control performance are improved. The magnetic screw is introduced into the automatic door system;high-efficiency conversion from rotation motion to the linear motion is achieved; intermediate mechanisms are reduced; and the automatic door system has important theoretical value and practical value in progress and development of the automatic door industry.

Description

technical field [0001] The invention relates to a reluctance type magnetic screw automatic door system and a positioning method thereof, which are applicable to household, industry, daily life and other aspects, and belong to the field of electrical technology. Background technique [0002] With the rapid development of social economy and automatic control technology, the automation level of building facilities has also been continuously improved, and automatic doors have been used more widely in various occasions. Since 2000, the use of automatic doors in my country has increased year by year, and the average growth rate Reach 20% to 30%. The demand for automatic door products not only promotes the continuous progress of related industries, but also puts forward higher requirements for the reliability and stability of automatic door drive devices and key technologies. [0003] Traditional automatic doors are generally driven by a rotating motor, and are pulled by gears, rac...
