摘要:門是伴隨著人們的文明而誕生的，隨著科學的發(fā)展，門的種類越來越多，技術也越來越復雜。自動門從理論上理解應該是門的使用觀念的延伸，是人們根據(jù)需要對門的功能的提升和完善。所以對自動門的認識應該從人對門功能的要求開始。作為建筑物一部分的門，從最基本的意義上講，要同時滿足隔離外部環(huán)境和不妨礙人的通行這兩種要求。 自動門控制系統(tǒng)的設計中，系統(tǒng)的安全性和穩(wěn)定性是很重要的。過去的自動門系統(tǒng)大多采用繼電器邏輯控制方式，這種控制方式故障率高、可靠性低、維護不便。基于此，本設計選用可靠性高、性能穩(wěn)定、維護方便的PLC設計自動門控制系統(tǒng)，在設計中對PLC進行選型、設計了PLC外部硬件電路和滿足本控制系統(tǒng)的梯形圖程序。最后通過模擬調(diào)試，結(jié)果表明硬件與軟件設計均能夠滿足自動門控制系統(tǒng)的要求。 當自動感應門門扇要完成一次開門與關門， 感應探測器探測到有人進入時，將脈沖信號傳給主控器，主控器判斷后通知馬達運行，同時監(jiān)控門的運行位置，以便通知馬達在一定時候加速和進入慢行運行。馬達得到一定運行電流后做正向運行，將動力傳給同步帶，再由同步帶將動力傳給吊具系統(tǒng)使自動感應門扇開啟；自動感應門扇開啟后由控制器作出判斷，如需關自動感應門，通知馬達作反向運動，關閉自動感應門。 關鍵詞：PLC；變速；驅(qū)動裝置；感應器
Abstract:The door is accompanied by the people and the birth of civilization, with the development of science, more and more kinds of door, technology is also more and more complicated. The automatic door is the door should understand theoretically the use of extension of the concept, it is people according to the need of the opposite the ascension of the function and perfect. So for the understanding of the automatic doors should be from the opposite the requirements of people began to function. As part of the building of the door, from the most basic sense, at the same time satisfy the isolation external environment and does not interfere with people of go through the these two requirements. Automatic control system design, system security and stability is very important. The past automatic door system is used mostly relay logic control way, that this kind of control mode high failure, reliability, low maintenance inconvenience. Based on this, this design choose high reliability, stable performance and maintenance convenient PLC automatic control system design, the design of PLC for the type selection, design the PLC external hardware circuit and meet the control system ladder diagram program. Through the simulation test, the result shows that the hardware and software design are able to meet the requirements of the automatic control system. When automatic induction door its doors to complete a open and close the door, induction detector detect someone in, will the pulse signal to the main controller, the main controller after judge notice motor operating, and monitor the operation of the gate location, in a certain time to notice the motor speed up and into the slow running. Get a motor running do after the current positive run, drive to synchronous belt, again by synchronous belt drive to sling system make automatic induction its doors open; Automatic induction doors open by a controller to judge, if need to shut automatic induction door, notice the motor do reverse movement, off the automatic induction door. Keywords: PLC,shifting, device drivers, the sensor
