【摘要】：随着中国经济的全面腾飞,城市外来人口增加、社会环境复杂化、人际关系淡化、邻里互助团结精神减弱,入室盗窃的犯罪率逐年增加,此类盗窃案件的发生与家中无人看守、安防系统不完善等因素有着密切的关联。目前市场上安防系统产品基本上都是被动式安防系统,可以分为远程视频监控、智能楼宇对讲、联网报警等几大比较相对独立系统。然而,本课题主要以家中无人状况为实际需求出发,研究并设计一套完整的主动式家庭场景还原智能安防系统。该安防系统主要是针对家中无人状态,模拟还原正常生活场景,兼备家用电气设备自动化、网络信息化集系统、服务、管理为一体的高效、安全、实时、全方位的智能安防系统。首先,本课题分析了家庭智能安防系统的背景、意义以及国内外的发展状况,以入室盗窃犯罪率逐年增加与家庭的实际需求为基础,提出家庭场景还原智能安防系统的设想,分析并得出家用电器设备使用时间表。探讨信息传输方式并确定系统传输设计方案,主要研究了电力线载波通信技术中宽带及窄带通信,重点分析了频移键控的调制方案。其次,从系统的整体设计出发,细化家庭场景还原智能安防系统,得出系统总体设计框图、数据采集原理图、家用电器控制图及电力线家庭网关的设计框图,使用Altium Designer画图软件设计原理图并制作PCB电路板。系统软件采用结构化、模块化程序设计方式主要包括：ARM主控板Linux系统平台搭建、LCD与WEB服务器的移植、QT图形界面与电力线载波通信程序设计；从机的灯光控制程序、火焰与可燃气体传感器程序以及电力线载波通信程序设计部分组成。最后,对家庭场景还原智能安防系统进行系统测试、发现问题并解决以及整体功能实现,结果表明整个系统基本完成各项功能指标。本设计基于嵌入式Linux系统ARM平台综合运用了电力线载波通信技术、传感器技术、QT图形化界面设计和微控制处理技术,实现了家庭场景还原智能安防系统。本设计针对性强、成本低、使用方便,不需要改变家庭的布线结构,有广阔的应用前景。
[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.
