For this situation, this paper uses the Siemens S7200 and designs the system to control the campus lighting system instead of traditional artificial control，Programmable Logical Controller intelligent control system was adopted on the new campus, the control system is reliable enough to meet the requirement of campus lighting, The system mainly includes incident the output signal of the road、the decorative lights and the green fields. Which poses the I/0 allocation tables and flowing diagram and the ladder diagram control programs of the illumination system of the campus. Through the simulation, it is able to turn to manual control from the automatic system when the facilities generate the phenomenon of the malfunction and abnormal,the automatic system turn on after people to find and orderly deal with the malfunction ,and fulfills the requirements of the system of the intelligent control.Key words: The illumination system。基于 PLC 的校園照明智能控制系統(tǒng)設(shè)計［摘 要］目前，大多數(shù)校園照明系統(tǒng)仍然使用人工控制，其缺點是控制復(fù)雜、修理困難、容易發(fā)生誤動作。最后經(jīng)過模擬仿真運行，能夠?qū)崿F(xiàn)當設(shè)備發(fā)生故障或出現(xiàn)某些不正常運行情況時，由自動控制變換人工控制，在排除故障后再次實現(xiàn)自動控制滿足照明智能控制系統(tǒng)的要求。 intelligent control目 錄1 引 言 ...................................................................3 選題背景和意義 ......................................................3 PLC 在國內(nèi)外的發(fā)展狀況 ...............................................2 設(shè)計的主要內(nèi)容及技術(shù)要求 ............................................2 主要內(nèi)容.........................................................2 具體技術(shù)要求.....................................................22 智能照明控制系統(tǒng)總體方案設(shè)計 ............................................3 照明系統(tǒng)的功能需求分析 ..............................................3 系統(tǒng)設(shè)計的基本步驟及功能組成 ........................................3 智能照明控制系統(tǒng)設(shè)計過程簡述.....................................3 智能照明控制系統(tǒng)設(shè)計基本步驟和方法...............................4 智能照明控制系統(tǒng)設(shè)計的功能組成...................................43 硬件設(shè)計 ................................................................5 線路結(jié)構(gòu)設(shè)計 ........................................................5 控制線路設(shè)計.....................................................5 控制器件的選型...................................................6 PLC 的設(shè)計 ...........................................................7 PLC 在控制系統(tǒng)中的要求 ...........................................7 PLC 選型 .........................................................8 S7200 系列 PLC...................................................9 I/O 地址分配 .....................................................9 ...............................................................10 程序流程 ...........................................................10 STEP7Micro/WIN 編程軟件 .......................................11 STEP7Micro/WIN 編程軟件主界面及基本組成 ...................12 梯形圖的編寫....................................................12 時鐘設(shè)置及讀寫..................................................13 系統(tǒng)的控制程序 .....................................................15 分時控制方案....................................................15 分時智能控制程序編制............................................15 三時段控制程序..................................................15 季節(jié)自動選擇程序................................................165 控制程序的調(diào)試與仿真 ...................................................16 程序調(diào)試 ...........................................................16 系統(tǒng)仿真 ...........................................................17結(jié)束語 ...................................................................21參考文獻 .................................................................22附錄 .....................................................................23致謝 .....................................................................281 引 言 選題背景和意義隨著工業(yè)化高速發(fā)展，能源問題成為人們關(guān)注的焦點，因為能源的消耗除了其直接的經(jīng)濟損失外，還會帶來碳排放量的增加，惡化環(huán)境，所以節(jié)約能源一直是生活、生產(chǎn)中的一個主題。校園的建設(shè)要
