【摘要】：随着科学技术的发展和人们生活水平的提高,物联网智能家居和安防行业蓬勃发展,在物联网推动下势必有越来越多的家庭建立智能、安全的家居空间。本设计基于嵌入式OpenWRT的家庭智能安防系统,主要是以Linux系统开发的控制系统为核心,依据家庭安防智能化的理念,为家庭成员提供一个安全、舒适、便捷的生活环境,实现安防实时监测、视频数据传送与转换、数据智能分析处理等功能,为家居环境的安全和随时随地的监控提供必要的保障。本文在分析了智能家居系统的国内外现状、以及发展趋势的基础上,提出了一种基于OpenWRT的智能家庭安防系统设计。本设计所研究的家庭智能安防系统,充分利用了家庭中不可缺少的路由器。路由器采用以OpenWRT为内核的嵌入式系统,其作为中心平台,接收和处理外围单片机控制电路传输过来的信息。用户可以通过移动端安装的Android客户端软件与系统进行交互,这使的本系统具有视频监控、传感器监控、远程信息传输与智能报警功能。文章研究了智能家庭安防的关键技术,如对OpenWRT的相关介绍、MJPG-streamer的简要介绍等。并对系统进行了总体方案的设计和需求分析,将系统可大致分成三大块来实现：路由器的设计的实现、外围电路设计的实现及Android客户端设计的实现。首先对路由器这块进行相关的设计,提出了路由器的系统设计方案,路由器软硬件架构及将MJPG-streamer移植到路由器中。其次在对外围电路进行相关设计,包括实现其硬件架构、无线通信模块的设计。最后就是对Android客户端的设计。论文的创新在于：1、本设计的远程安防监控系统,着力研究适合于大众家居的安防系统,具有廉价、安装方便、易于普及等特点；2、本设计的开源性OpenWRT系统,具有可扩展性和高智能化,应用范围广泛,功能强大。市面上大多品牌的路由器,大多可以刷写OpenWRT操作系统,从而降低了本系统的实现成本；3、可视化的信息服务接口,能通过Android终端提供信息服务；4、本设计的变频无线传输系统,充分利用当前家居已有的布线来实现无线信号的扩展,方案简便,可以做到全屋无死角的无线覆盖,具有较好的推广前景。
[Abstract]:With the development of science and technology and the improvement of people's living standard, intelligent networking Home Furnishing and security industry vigorous development, the establishment of intelligent networking promotion is bound to have more and more families, the safety of Home Furnishing space. This design smart home security system based on embedded OpenWRT is the main control system of Linux system development as the core on the basis of family security, the concept of intelligent, for family members to provide a safe, comfortable and convenient living environment, the realization of security monitoring, video data transmission and conversion, intelligent data analysis and processing functions, monitoring for environmental safety and the Home Furnishing whenever and wherever possible to provide the necessary protection. Based on the analysis of the current situation of intelligent Home Furnishing system at home and abroad, and based on the trend of development, this paper puts forward a design of intelligent home security system based on OpenWRT. The design of intelligent home. Control system, make full use of the family indispensable router. Router adopts the embedded system with the core of OpenWRT, as the center platform, receiving and processing the peripheral control circuit of SCM transmitted information. Users can install Android client software and system through the mobile terminal to interact, which makes the system with video surveillance the sensor monitoring, remote information transmission and intelligent alarm function. This paper studies the key technologies of intelligent home security, such as the introduction of OpenWRT, MJPG-streamer are briefly introduced. Then the system design and demand analysis of the overall scheme, the system can be roughly divided into three blocks to achieve: to achieve the design of the router. The realization of Android client and design the peripheral circuit design. Firstly, the related design of the proposed router, router system The design scheme, hardware and software architecture and the router MJPG-streamer will be ported to the router. The peripheral circuits are related to design, including the realization of the hardware architecture, the design of wireless communication module. The last part is about the design of the Android client. The innovation of this paper lies in: 1, the design of remote monitoring system, and focus on the security system. Suitable for mass Home Furnishing is cheap, convenient installation, easy popularization and other characteristics; 2, open source OpenWRT system of this design, scalable and high intelligence, wide application range and powerful function. On the market most brands of routers, most can brush to write the OpenWRT operating system, which reduces the cost of the 3, the information service system; visual interface, can provide information services through the Android terminal; 4 frequency wireless transmission system of this design, make full use of the existing Home Furnishing cloth Line to achieve the expansion of the wireless signal, the scheme is simple, can achieve the whole house without dead angle wireless coverage, and has a good promotion prospect.
