【正文】 , reduce the risk of error, has very important significance. System will be the candidate information encapsulation to qr code, by qr code scanning technology for inputting information, very good to ensure the safety, reliability and feasibility of information. Qr code is simple, qr code technology mature, can be seen everywhere in our daily life qr code, can be applied to a variety of promotional mode, the late for promotion, software cost greatly reduced. Number of examination of test band 4 and band 6, large amount of information input, manual entry plicated timeconsuming. This system use cell phones to take an examination of the 河北工業(yè)大學 2020 屆本科畢業(yè)論文 III bar code scanning on the test paper, can plete lack of information collection, summary and school work, pared with the traditional methods greatly reduce the workload of the examiners。s information collection, there will be no copying errors. So scans the bar code method is efficient, safe, and has very important significance in the practical work. Keywords： College English CET examination management system, the android applications, MYSQL database, WEBSERVER server, qr code, bar code table. 河北工業(yè)大學 2020 屆本科畢業(yè)論文 IV 目錄 一、緒論 ................................................................... 1 .................................................... 1 國內(nèi)外研究現(xiàn)狀 ...................................................... 1 二、項目需求分析 ........................................................... 2 ........................................................ 2 功能需求分析 ....................................................... 2 信息需求分析 ....................................................... 3 接口描述 .......................................................... 4 三、軟件設(shè)計說明 ........................................................... 5 ............................................................ 5 .................................................. 5 系統(tǒng)流程設(shè)計 .................................................. 6 .................................................. 7 .......................................................... 7 ................................................ 7 ............................................ 9 ....................................................... 11 文件夾組織結(jié)構(gòu) ..................................................... 11 類組織結(jié)構(gòu)和界面組織結(jié)構(gòu) .......................................... 12 系統(tǒng)實現(xiàn) .......................................................... 13 ................................................... 13 四、作品特色及難點分析 ..................................................... 14 ................................................... 14 ....................................................... 17 ....................................................... 17 ....................................................... 17 五、軟件測試說明 .......................................................... 18 ............................................................... 18 項目簡介 ..................................................... 18 參考資料 ..................................................... 18 ........................................................... 18 軟件測試目標 ................................................. 18 ................................................. 19 ....................................................... 19 接口實現(xiàn) .......................................................... 24 ........................................................... 25 結(jié)論與展望 ................................................................ 27 心得體會 .............................................................. 27 河北工業(yè)大學 2020 屆本科畢業(yè)論文 V 市場展望 .............................................................. 27 參考文檔 .................................................................. 28 致謝 ...................................................................... 30 河北工業(yè)大學 2020 屆本科畢業(yè)論文 1 一 、緒論 研究目的：由于近年來很多高校的學位證書不與四級成績關(guān)聯(lián)，且考試報名費 30 元對學生的經(jīng)濟影響不大，因此四六級考試缺考情況非常嚴重。因此當前的四六級考試缺考錄入方式是一種效率低下的工作 [7]。 系統(tǒng)將考生信息封裝到二維碼中，通過二維碼掃描技術(shù)獲取錄入信息，很好的保證了信息的安全性、可靠性、可行性 [1]。 研究意義：四六級考試缺考人數(shù)多，信息錄入量大，手工錄入繁瑣耗時 。因此掃描條形碼的方法高效、安全，
