【摘要】：隨著中國經(jīng)濟的全面騰飛,城市外來人口增加、社會環(huán)境復(fù)雜化、人際關(guān)系淡化、鄰里互助團結(jié)精神減弱,入室盜竊的犯罪率逐年增加,此類盜竊案件的發(fā)生與家中無人看守、安防系統(tǒng)不完善等因素有著密切的關(guān)聯(lián)。目前市場上安防系統(tǒng)產(chǎn)品基本上都是被動式安防系統(tǒng),可以分為遠(yuǎn)程視頻監(jiān)控、智能樓宇對講、聯(lián)網(wǎng)報警等幾大比較相對獨立系統(tǒng)。然而,本課題主要以家中無人狀況為實際需求出發(fā),研究并設(shè)計一套完整的主動式家庭場景還原智能安防系統(tǒng)。該安防系統(tǒng)主要是針對家中無人狀態(tài),模擬還原正常生活場景,兼?zhèn)浼矣秒姎庠O(shè)備自動化、網(wǎng)絡(luò)信息化集系統(tǒng)、服務(wù)、管理為一體的高效、安全、實時、全方位的智能安防系統(tǒng)。 首先,本課題分析了家庭智能安防系統(tǒng)的背景、意義以及國內(nèi)外的發(fā)展?fàn)顩r,以入室盜竊犯罪率逐年增加與家庭的實際需求為基礎(chǔ),提出家庭場景還原智能安防系統(tǒng)的設(shè)想,分析并得出家用電器設(shè)備使用時間表。探討信息傳輸方式并確定系統(tǒng)傳輸設(shè)計方案,主要研究了電力線載波通信技術(shù)中寬帶及窄帶通信,重點分析了頻移鍵控的調(diào)制方案。 其次,從系統(tǒng)的整體設(shè)計出發(fā),細(xì)化家庭場景還原智能安防系統(tǒng),得出系統(tǒng)總體設(shè)計框圖、數(shù)據(jù)采集原理圖、家用電器控制圖及電力線家庭網(wǎng)關(guān)的設(shè)計框圖,使用Altium Designer畫圖軟件設(shè)計原理圖并制作PCB電路板。系統(tǒng)軟件采用結(jié)構(gòu)化、模塊化程序設(shè)計方式主要包括：ARM主控板Linux系統(tǒng)平臺搭建、LCD與WEB服務(wù)器的移植、QT圖形界面與電力線載波通信程序設(shè)計；從機的燈光控制程序、火焰與可燃?xì)怏w傳感器程序以及電力線載波通信程序設(shè)計部分組成。 最后,對家庭場景還原智能安防系統(tǒng)進(jìn)行系統(tǒng)測試、發(fā)現(xiàn)問題并解決以及整體功能實現(xiàn),結(jié)果表明整個系統(tǒng)基本完成各項功能指標(biāo)。 本設(shè)計基于嵌入式Linux系統(tǒng)ARM平臺綜合運用了電力線載波通信技術(shù)、傳感器技術(shù)、QT圖形化界面設(shè)計和微控制處理技術(shù),實現(xiàn)了家庭場景還原智能安防系統(tǒng)。本設(shè)計針對性強、成本低、使用方便,不需要改變家庭的布線結(jié)構(gòu),有廣闊的應(yīng)用前景。
[Abstract]:With the rapid development of Chinese economy, the increase of foreign population, the complication of social environment, the weakening of interpersonal relationship, the weakening of the spirit of neighborhood solidarity, the crime rate of burglary is increasing year by year. The occurrence of this kind of theft cases is closely related to the factors such as no guard at home, imperfect security system, etc. At present, the products of security system are basically passive security system, which can be divided into remote video surveillance. Intelligent building intercom, network alarm and other relatively independent systems. This paper studies and designs a complete active home scene restoration intelligent security system, which is mainly aimed at home unmanned state, simulation restore normal life scene, and home electrical equipment automation. Network information system, service, management as one of the high-efficiency, security, real-time, all-directional intelligent security system. First of all, this paper analyzes the background, significance and the development of home intelligent security system, based on the increasing crime rate of burglary and the actual needs of the family year by year. This paper puts forward the assumption of home scene restoring intelligent security system, analyzes and obtains the use schedule of household appliances, probes into the mode of information transmission and determines the design scheme of system transmission. The broadband and narrowband communication in power line carrier communication technology is studied, and the modulation scheme of frequency shift keying is analyzed. Secondly, from the overall design of the system, refined home scene restore intelligent security system, get the system overall design block diagram, data acquisition schematic diagram, home appliances control diagram and power line home gateway design block diagram. Use Altium Designer drawing software to design schematic diagram and make PCB circuit board. The system software is structured. The modular program design method mainly includes the design of the Linux system platform of the main control board of Linux and the design of the QT graphic interface and the power line carrier communication program between the LCD and the WEB server. The light control program of the slave, the flame and combustible gas sensor program and the power line carrier communication program are designed. Finally, the system test of the home scene restore intelligent security system is carried out, the problem is found and solved, and the whole function is realized. The result shows that the whole system basically completes each function index. This design is based on the embedded Linux system ARM platform, the integrated use of power line carrier communication technology, sensor technology QT graphical interface design and micro-control processing technology. This design has the advantages of strong pertinence, low cost, convenient use, no need to change the wiring structure of the home, and has a broad application prospect.
