停車場收費(fei)系(xi)統(tong)設(she)(she)計思路：1.硬件(jian)設(she)(she)備需(xu)(xu)求(qiu)分(fen)析。需(xu)(xu)要(yao)(yao)一臺服務器(qi)(qi)作為數據(ju)庫(ku)(ku)主(zhu)機(ji)，用(yong)于存儲車輛信息、計費(fei)規(gui)則等(deng)數據(ju)；還需(xu)(xu)要(yao)(yao)部署(shu)前(qian)(qian)端終(zhong)端設(she)(she)備和(he)(he)道閘(zha)機(ji)具（如桿），實現(xian)車牌識別和(he)(he)自動(dong)放行(xing)功能；另外配置相應(ying)的(de)(de)(de)(de)(de)網絡布(bu)線及安全設(she)(she)施確保(bao)系(xi)統(tong)的(de)(de)(de)(de)(de)穩定運行(xing)和(he)(he)維護(hu)便利性。2.系(xi)統(tong)架構(gou)與(yu)(yu)模塊劃分(fen)。根(gen)據(ju)上述要(yao)(yao)求(qiu)可劃分(fen)為兩(liang)個主(zhu)要(yao)(yao)部分(fen)進行(xing)開發(fa)設(she)(she)計：一是軟件(jian)平臺搭建，包括操作系(xi)統(tong)安裝以(yi)及相關軟件(jian)的(de)(de)(de)(de)(de)和(he)(he)使用(yong)說明(ming)文檔的(de)(de)(de)(de)(de)提供；二是應(ying)用(yong)程(cheng)(cheng)序(xu)的(de)(de)(de)(de)(de)開發(fa)設(she)(she)計與(yu)(yu)測試上線流程(cheng)(cheng)的(de)(de)(de)(de)(de)管(guan)理，需(xu)(xu)要(yao)(yao)進行(xing)嚴格的(de)(de)(de)(de)(de)代碼審查和(he)(he)技(ji)(ji)術(shu)(shu)把關以(yi)保(bao)障產品(pin)品(pin)質(zhi)和(he)(he)服務質(zhi)量。因此我們采用(yong)前(qian)(qian)后端分(fen)離的(de)(de)(de)(de)(de)方(fang)式構(gou)建該停車管(guan)理系(xi)統(tong)。后端的(de)(de)(de)(de)(de)控制器(qi)(qi)基于NodeJS語言(yan)編(bian)寫并使用(yong)了(le)(le)開源的(de)(de)(de)(de)(de)運動(dong)控制庫(ku)(ku)IOC-Controller用(yong)以(yi)驅動(dong)電機(ji)完成抬(tai)杠/降杠動(dong)作，同時使用(yong)實現(xian)了(le)(le)車主(zhu)客戶端與(yu)(yu)服務器(qi)(qi)的(de)(de)(de)(de)(de)實時通信以(yi)達到(dao)遠程(cheng)(cheng)監(jian)控的(de)(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)(de)；前(qian)(qian)段則采用(yong)了(le)(le)HTML5、CSS3和(he)(he)JavaScript等(deng)技(ji)(ji)術(shu)(shu)棧(zhan)為駕乘者提供了(le)(le)友好的(de)(de)(de)(de)(de)人機(ji)交互體驗。此外在(zai)技(ji)(ji)術(shu)(shu)選型方(fang)面還對(dui)圖像處理算法進行(xing)了(le)(le)深入的(de)(de)(de)(de)(de)研究(jiu)和(he)(he)應(ying)用(yong)使得(de)本(ben)停車管(guan)理系(xi)統(tong)的(de)(de)(de)(de)(de)準確率(lv)和(he)(he)效率(lv)得(de)到(dao)了(le)(le)顯著提升。通過以(yi)上方(fang)式可以(yi)滿足(zu)用(yong)戶的(de)(de)(de)(de)(de)需(xu)(xu)求(qiu)并且保(bao)證(zheng)產品(pin)的(de)(de)(de)(de)(de)質(zhi)量和(he)(he)可靠性。
