The Design of Automatic Sliding Door For Family
Abstract
With the development of society,advances in technology and people's living standards gradually improved.A variety of convenient automatic control system begin come up in people's lives. There is growing emphasis on smart living environment. The design of automatic doors is one of an important content.This design is based on the principle of economical and practical and use the parallel infrared transmitter and receiver signal acquisition, coupling the relay to achieve strong and weak electrical connections. Wiring relay interlocking the door to achieve the headstock , magnetic trip circuit limit reset switch.The door consists of the wood structure. Rack and pinion engagement drag the door. When people go in or out , the infrared transceiver device collect the corresponding signal and deliver it to the control part. Signaling part of the opening and closing of the relay interlocking control the motor when to transfer, delay and reverse, and have protection to prevent the people injured when they through the door.
