【正文】 摘 要 I 摘 要 目前，家庭居住環(huán)境的采光及避光問題主要采用的是手動開閉窗簾，手動開閉不僅費(fèi)力而且很多方面不夠人性化，會對用戶造成一定的困擾，本文設(shè)計的自動窗簾控制系統(tǒng)可以解決這些問題。本文主要闡述了自動窗簾控制的設(shè)計過程。以 AT89C52 單片機(jī)為控制核心，以光敏電阻和溫度傳感器為傳感器件，以步進(jìn)電機(jī)為執(zhí)行器件。 在設(shè)計的同時對單片機(jī)的理論基礎(chǔ)和外 圍擴(kuò)展知識進(jìn)行了比較全面準(zhǔn)備。 硬件采用分塊的模式，對整個系統(tǒng)的電路設(shè)計進(jìn)行分析，分別給出了系統(tǒng)整體框圖、顯示電路、檢測電路、系統(tǒng)總控制模塊、等相關(guān)電路；隨后說明系統(tǒng)軟件的編寫過程，同樣采用的是分塊的模式，且每一個模塊都給出了相應(yīng)的流程圖。 本設(shè)計利用單片機(jī)實(shí)現(xiàn)了半自動控制、自動控制、定時控制的相互轉(zhuǎn)換，智能的控制窗簾的動作。通過調(diào)試，手動開關(guān)窗簾、自動開關(guān)窗簾等控制方面的設(shè)計基本達(dá)到了預(yù)期效果。具有較強(qiáng)的實(shí)用價值。 關(guān)鍵詞 ：單片機(jī)；自動窗簾；步進(jìn)電機(jī)；自動控制 新疆工程學(xué)院畢業(yè)設(shè)（論文） II Abstract III Abstract Now， according to the requirements of living environments. This paper describes the process of intelligent curtain controller. This design uses AT89C52 microcontroller as the control， introduce microcontrollerbased optical curtain curtain system， the main structural principle of the hardware and software programming to the design for monolithic integrated circuits， and peripheral to expand the basic the theories of knowledge was fairly prehensive the model of hardware used， the circuit design of the entire system to analyze the overall block diagram of the system are given， display circuit， photoelectric switch circuit， system control module， power conversion circuits，protection circuits and other related circuit； then describes the software the preparation process， but also by the subblock pattern， with each module to draw a corresponding flow chart. In this paper， use the AT89C52 microcontroller， according to their different modes，to achieve semiautomatic control， automatic control， timing control of the conversion and intelligent motion control curtains. Debugging by simulation， clock control， manual switch curtains， the curtains automatically switch the basic design of such control to achieve the desired effect， with a strong practical value.
