附 錄附錄A 外文資料Intelligent parking lotIntelligent parking management system uses advanced technology and highly automated mechanical and electrical equipment, mechanical, and electronic putercontrolled equipment, and intelligent IC card technology bine management can be achieved through the puter management of vehicle access, automatic data storage function, the realization of de machine operation and provide efficient management of the system. Smart new car park will be living concepts and architecture, information technology, puter electronics technology, such as the perfect bination of modern hightech to provide a simple, easytouse, advanced system of human nature. It relies on hightech, peopleoriented, graphical manmachine interface operation, providing a more safe, fortable, convenient, fast and open intelligent, informationbased living space, promoting the healthy development of human environment. 1 parking lot at home and abroad mainly in the following several types mechanical parking Mechanical parking car park is mainly a kind of mechanical means parking the car park pletely by mechanical parking equipment such as tractor driving machine, driven wheels, car panels, sliding device, control cabinet, called the operation site, Rotary lift devices, handling devices, etc.. Lifting and transferring is divided into categories, vertical circulation category, the level of cycletype, multicycletype, flat type of mobile, vertical categories, such as the type of simple movements. Because of its unique and diverse way of parking, has a strong application. It covers an area of the main advantages of small, diverse selection can be bined with site specific characteristics of the design, but also with other means to implement a bination of a high degree of automation, easy operation, management and maintenance is also easier with quantitative parking characteristics. Plane parking system Intelligent parking system parking systems for their plane to take the main inductive way IC card readers, so the car park is also called inductive system. At present, China is still in the car park car park is mainly flat, generally built in the basement of buildings, there are a number of public areas such as the Plaza, the road side as the car park, followed by the hotel, enterprises, factories, and other units of their own planning and design of the car park. Smart parking Intelligent parking system is also called the vertical lift or elevatortype parking system parking systems. It is a set of equipment, operation, security, monitoring, maintenance, management of the intelligent system as a whole, the touchscreen humanmachine interface, operation and use is also very convenient, with intelligent management and charges of the system. Its high degree of intelligence testing and perfecting the service system can be impaired also run zero. It is characterized by the largest original time control functions, the realization of subperiods, stratified parking control, effectively improve the utilization of parking spaces. Password through the keyboard and the IC card can be realized vehicle access, the process of charging, easy operation and convenient access。[14] ANALOG technology of AT89C51[EB/OL].White Paper,。[6] 肖景和,、熱釋與超聲波遙控電路,人民郵電出版社,2003。 圖5 1 打開開關(guān) 圖5 2 擋住一個(gè)停車位 圖5 3 擋住兩個(gè)停車位 圖5 4 擋住三個(gè)停車位 展望這次單片機(jī)最小系統(tǒng)及外圍電路的設(shè)計(jì),我查閱了大量的資料,每設(shè)計(jì)一個(gè)模塊,我都弄懂了其工作原理,雖然我之前也用過(guò)Altium Designer 畫過(guò)原理圖和PCB板,但是對(duì)這個(gè)軟件的使用還不是很熟練,在布線的時(shí)候遇到了很多困難,剛開始畫完原理圖經(jīng)過(guò)編譯之后出現(xiàn)了很多錯(cuò)誤和警告,在生成PCB的時(shí)候封裝和原理圖又對(duì)不上號(hào),布線的時(shí)候很多線走不過(guò)來(lái),通過(guò)不斷的調(diào)試,最后終于順利完成了設(shè)計(jì)。這次的畢業(yè)設(shè)計(jì)讓我受益匪淺。俗話說(shuō)啊:千萬(wàn)不能眼高手低。開始 動(dòng)態(tài)數(shù)碼管初始化顯示緩沖區(qū)首地址傳送位碼傳送段碼顯示計(jì)數(shù)返回圖42數(shù)碼管流程圖第5章 結(jié)論與展望 結(jié)論畢業(yè)設(shè)計(jì)期間,我所設(shè)計(jì)的是小區(qū)停車場(chǎng)車位自動(dòng)顯示系統(tǒng),經(jīng)過(guò)多次調(diào)試基本上可以滿足設(shè)計(jì)要求,這個(gè)畢業(yè)設(shè)計(jì)是對(duì)小區(qū)停車場(chǎng)車位自動(dòng)顯示系統(tǒng)的簡(jiǎn)單模擬,可以實(shí)現(xiàn)車輛的檢測(cè)、管理等功能。⑵特征位式:每位二進(jìn)制數(shù)控制一個(gè)小數(shù)點(diǎn)的亮暗情況,一個(gè)字節(jié)同時(shí)控制8個(gè)。因?yàn)槟菢映鲥e(cuò)了,也不知道是哪部分出錯(cuò)了,找錯(cuò)誤是一個(gè)難題,還得一個(gè)一個(gè)模塊的找。 設(shè)計(jì)方法軟件部分設(shè)計(jì)是畢業(yè)設(shè)計(jì)中最集中難點(diǎn)所在,所謂軟件設(shè)計(jì)就是把硬件具體功能需求變換成軟件的具體設(shè)計(jì)方案(即模塊結(jié)構(gòu))的過(guò)程。譯碼器輸出與輸入代碼有唯一的對(duì)應(yīng)關(guān)系。它的內(nèi)部包含四組形式完全相同的運(yùn)算放大器,除電源共用外,四組運(yùn)放相互獨(dú)立,如圖37所示。(呵呵,可以試驗(yàn)一下,得到合適自己的標(biāo)準(zhǔn))二、 紅外收發(fā)對(duì)管的應(yīng)用[10] 其實(shí)紅外對(duì)管與光電傳感器RPR220是一樣的東西,不一樣的是紅外對(duì)管是分立的器件。⑴怎么看這個(gè)傳感器的管腳圖:印有RPR220字樣的那一面向上,管腳對(duì)著自己,這樣看過(guò)去就如圖34所示 圖34管腳圖⑵ RPR220的電路圖原理如圖35所示 ① 12端的紅外二極管發(fā)出紅外光,經(jīng)白紙(黑色會(huì)吸收光線,無(wú)反射)反射回來(lái)給34端的紅外接收管接收,當(dāng)接收到紅外線,則34導(dǎo)通,常用電路如下:圖35 RPR220電路原理圖② 當(dāng)檢測(cè)到黑線時(shí),此時(shí)也就是紅外接收管沒(méi)有接收到反射回來(lái)的紅外光,34的紅外接收三極管截止,則在RPR220的3管腳輸出一個(gè)電壓。降壓后還是交流電壓,所以需要整流電路把交流電壓轉(zhuǎn)換成直流電壓。當(dāng)振蕩器工作時(shí),RST引腳出現(xiàn)兩個(gè)機(jī)器周期以上高電平將是單片機(jī)復(fù)位。在flash編程和校驗(yàn)時(shí),P2口也接收高8位地址字節(jié)和一些控制信號(hào)。此外,()和時(shí)器/計(jì)數(shù)器2 的觸發(fā)輸入(),具體如下表所示。對(duì)P0端口寫“1”時(shí),引腳用作高阻抗輸入。片上Flash允許程序存儲(chǔ)器在系統(tǒng)可編程,亦適于常規(guī)編程器。 具有以下標(biāo)準(zhǔn)功能: 8k字節(jié)Flash,512字節(jié)RAM, 32 位I/O 口線,看門狗定時(shí)器,內(nèi)置4KB EEPROM,MAX810復(fù)位電路,3個(gè)16 位定時(shí)器/計(jì)數(shù)器,4個(gè)外部中斷,一個(gè)7向量4級(jí)中斷結(jié)構(gòu)(兼容傳統(tǒng)51的5向量2級(jí)中斷結(jié)構(gòu)),全雙工串行口。方案二:采用LED八段顯示器。方案一:采用紅外線對(duì)管對(duì)進(jìn)入停車場(chǎng)的車輛數(shù)量進(jìn)行采集、然后再將紅外線對(duì)管采集的數(shù)據(jù)傳送給STC89C52單片機(jī)和ML324進(jìn)行數(shù)據(jù)處理,數(shù)據(jù)處理完以后再傳輸給數(shù)碼管顯示車輛的數(shù)量,數(shù)碼管會(huì)自動(dòng)加一,與此同時(shí)會(huì)有聲音提示以示有車輛進(jìn)入停車位。 車輛牌照定位與識(shí)別是計(jì)算機(jī)視覺(jué)與模式識(shí)別技術(shù)在智能交通領(lǐng)域應(yīng)用的重要研究課題之一:該技術(shù)應(yīng)用范圍非常廣泛, 其中包括: (1) 交通流量檢測(cè); (2)交通控制與誘導(dǎo);(3) 機(jī)場(chǎng)、港口等出入口車輛管理;(4) 小區(qū)車輛管理;(5) 闖紅燈等違章車輛監(jiān)控;(6) 不停車自動(dòng)收費(fèi);(7) 道口檢查站車輛監(jiān)控;(8) 公共停車場(chǎng)安全防盜管理;(9) 計(jì)算出行時(shí)間;(10) 車輛安全防盜、查堵指定車輛等。車輛牌照定位與識(shí)別是計(jì)算機(jī)視覺(jué)與模式識(shí)別技術(shù)在智能交通領(lǐng)域應(yīng)用的重要研究課題之一, 該技術(shù)應(yīng)用范圍非常廣泛。其潛在市場(chǎng)應(yīng)用價(jià)值極大,有能力產(chǎn)生巨大的社會(huì)效益和經(jīng)濟(jì)效益。關(guān)鍵詞: STC89C52單片機(jī) LM324 紅外線對(duì)管 數(shù)碼管AbstractCar park management system is in order to improve the efficiency of parking lot, munication system, the relevant latest achievements in the field of science and technology development of reasonable and effective application to the district parking management system perfecting and developing.
