【摘要】：隨著機(jī)動(dòng)車(chē)數(shù)量的大幅度增加，交通管理現(xiàn)狀和社會(huì)需求的矛盾也越來(lái)越突出，單一的人工控制已不能滿(mǎn)足需求，其中闖紅燈造成交通秩序混亂、堵塞及引發(fā)交通事故。電子警察產(chǎn)品普遍可靠性低、功能單一、價(jià)格昂貴，阻礙了交通行業(yè)的發(fā)展。設(shè)計(jì)并開(kāi)發(fā)一套可靠性高、多功能、價(jià)格低廉的電子警察系統(tǒng)，可以緩解警力不足，提高道路管理效率，具有現(xiàn)實(shí)意義。 鑒于這種應(yīng)用背景，從功能、用例、性能的角度進(jìn)行需求分析和總體設(shè)計(jì)，構(gòu)建了一套穩(wěn)定、高效、廉價(jià)的前端系統(tǒng)，為公安交通管理部門(mén)提供了強(qiáng)有力的執(zhí)法證據(jù)。本文的主要工作包括： 1.從經(jīng)濟(jì)、技術(shù)、運(yùn)行環(huán)境角度，分析了前端系統(tǒng)的可行性，根據(jù)前端系統(tǒng)功能和性能兩方面的需求，提出了總體設(shè)計(jì)目標(biāo)與思路，同時(shí)，詳細(xì)敘述了各層次的職責(zé)和關(guān)鍵的技術(shù)思想。系統(tǒng)整合了緩沖技術(shù)、網(wǎng)絡(luò)通信、并發(fā)處理與同步、存儲(chǔ)優(yōu)化關(guān)鍵技術(shù)，，并且解決了圖片亮度、視頻截取等難題。 2.根據(jù)前端系統(tǒng)的功能和性能需求，闡述了各功能模塊及接口的設(shè)計(jì)與實(shí)現(xiàn)。用戶(hù)接口主要實(shí)現(xiàn)相機(jī)登錄、布防/撤防，內(nèi)部接口實(shí)現(xiàn)功能模塊的內(nèi)部連接，外部接口是前端系統(tǒng)和中心平臺(tái)的橋梁，通過(guò)中心協(xié)議實(shí)現(xiàn)對(duì)接上傳。 3.對(duì)前端系統(tǒng)進(jìn)行功能和性能測(cè)試，分別記錄卡口、電警圖片信息，并進(jìn)行對(duì)比分析，結(jié)果表明：前端系統(tǒng)的可靠性高，車(chē)輛成功捕獲率高達(dá)99%，圖片亮度調(diào)節(jié)方法有效提高了車(chē)牌識(shí)別率，保證了圖片的正確性。
[Abstract]:With the increase of the number of motor vehicles, the contradiction between traffic management status and social demand is more and more prominent. The single manual control can not meet the demand, among which running red light causes traffic order chaos, jam and cause traffic accidents. The low reliability, single function and high price of electronic police products hinder the development of traffic industry. It is of practical significance to design and develop an electronic police system with high reliability, multifunction and low price, which can alleviate the shortage of police force and improve the efficiency of road management. In view of this application background, the requirement analysis and overall design are carried out from the angle of function, use case and performance, and a set of stable, efficient and cheap front-end system is constructed, which provides strong law enforcement evidence for public security traffic management department. The main work of this paper includes: 1. The feasibility of the front-end system is analyzed from the angle of economy, technology and running environment. According to the demand of the function and performance of the front-end system, the overall design goal and thought are put forward, at the same time, The responsibilities and key technical ideas of each level are described in detail. The system integrates buffer technology, network communication, concurrent processing and synchronization, storage optimization key technologies, and solves the image brightness, video capture and other problems. 2. According to the function and performance requirement of the front-end system, the design and implementation of each function module and interface are expounded. The user interface mainly realizes camera login, deployment / withdrawal, internal interface to realize the internal connection of the function module, external interface is the bridge between the front end system and the central platform, and the docking and uploading is realized through the central protocol. 3. The function and performance of the front-end system are tested, and the information of the bayonet and electric alarm pictures are recorded and compared. The results show that the front-end system has high reliability. The vehicle acquisition rate is as high as 99%, and the image brightness adjustment method can effectively improve the license plate recognition rate and ensure the correctness of the picture.
