Direct-drive side-hung automatic door control device and control method thereof

Abstract

The invention discloses a direct-drive side-hung automatic door control device and a control method thereof. The control device comprises an STM32 single chip microcomputer, a CPLD pulse distribution circuit, an intelligent power module (IPM), a permanent magnetic synchronous linear motor, a hall position sensor, an infrared sensor, a man-machine interaction interface and a door panel. The door panel is driven by the permanent magnetic synchronous linear motor, the hall position sensor detects the position of the door panel, the infrared sensor detects people stream information on the inner side and on the outer side of the door panel, and the STM32 single chip microcomputer generates motor enable signals, motor operation direction signals, PWM signals and motor brake signals according to received position information, system control/inquiry information and the people stream information. The permanent magnetic synchronous linear motor serves as a drive mechanism, and a system is high in reliability and convenient to maintain. The STM32 single chip microcomputer serves as a control core, so that development cost is lowered, and performance is stable; parameter setting and information display are achieved by means of a man-machine interaction touch screen, and operation is easy.

Description

technical field [0001] The invention relates to a direct-drive automatic door control device and a control method thereof, which can be applied to direct-drive automatic door control in public places such as shopping malls and banks. Background technique [0002] With the development of the economy and the improvement of people's living standards, the application of automatic doors is becoming more and more extensive. It is now a must for many modern buildings such as hotels, supermarkets, and department stores. It can not only beautify the entrance and exit environment, but also has functions such as energy saving, dust prevention, and sound insulation. It is also an important indicator of building intelligence. [0003] At present, most of the domestic products are imported from abroad. There are many foreign companies that produce automatic doors, such as BLASL in Germany, TORMAX in Switzerland, PA in Italy, National in Japan and so on. These products have many function...
