【摘要】：随着经济社会的快速发展,正在兴起的基于物联网技术的智能家居使人们逐渐迈入以数字化和网络化为平台的智能化社会。安防系统是智能家居中的一个重要组成部分,目前它正朝着前端一体化、视频数字化、监控网络化、系统集成化的方向发展。随着WI-FI技术日益成熟,它正逐步广泛用于短距离无线高速网以及逐步地侵入无线传感器网络领域,把WI-FI技术和智能家居结合,让家庭安全更加可靠,家庭宽带更加便捷已成为日后高质量生活的一部分。本文设计的智能家居无线安防系统从低功耗、低成本,安装便捷出发,以德州仪器公司的首款单芯片无线微控制器Simplelink WI-FI CC3200为核心,与安防模块结合,实现智能家居无线安防系统的硬件设计和软件设计,完成家庭安防系统的应用实现。硬件设计包括各A/D转换电路、信息采集电路及通讯接口电路。软件方面,完成嵌入式WI-FI协议的实现,然后编写信息采集端的收发程序,通过家庭局域网和云平台结合,实现手机web端实时查看摄像头拍摄信息,实现家庭内情况的实时查看,以及手机APP实现对传感器的实时监控,包括人体红外检测和可燃气体检测,并实现通过手机控制家电。本文研究的主要创新点是将TI公司最新研发的首款单芯片无线微控制器SinpleLink Wi-Fi CC3200应用于智能家居设计,以及将Yeelink云和APP用在手机端对家庭实时监控和控制家电。CC3200作为最大的亮点之一,是业界第一个具有内置WI-FI连通性的单片微控制器单元(MCU),SimpleLink CC3200器件集成了高性能ARM Cortex-M4的无线MCU,由应用微控制器,WI-FI网络处理器和电源管理子系统组成。论文研究CC3200的参数规格和技术特性,设计相应的外围电路,以家庭局域网为背景,结合云平台,根据对智能家居无线安防系统的硬件和软件设计,完成基于CC3200的智能家居无线安防系统的应用实现,包括无线视频监控系统、人体红外感应安防报警系统、可燃气体监测报警系统以及综合家庭智能系统的构建,实现手机实时监控和控制家电。另一方面,在设计中,还去掉了CLOSED状态,让它一开始就处于LISTEN状态,来监听客户端的连接请求,避免了主动或被动打开的操作,对此嵌入式场合,更为高效。
[Abstract]:With the rapid development of economy and society, the rising intelligent home based on Internet of things (IOT) makes people step into an intelligent society based on digitization and networking.Security system is an important part of smart home. At present, it is developing towards front end integration, video digitization, network monitoring and system integration.With the maturity of WI-FI technology, it is widely used in short-range wireless high-speed networks and step by step intrusions into wireless sensor networks, combining WI-FI technology with smart home to make home more secure and reliable.More convenient home broadband has become a part of high-quality life in the future.The smart home wireless security system designed in this paper is based on the Simplelink WI-FI CC3200, the first single-chip wireless microcontroller of Texas Instruments, which is based on low power consumption, low cost and convenient installation, and is combined with the security module.The hardware design and software design of smart home wireless security system are realized, and the application of home security system is realized.The hardware design includes A / D conversion circuit, information acquisition circuit and communication interface circuit.In the aspect of software, the realization of embedded WI-FI protocol is completed, and then the transceiver program of information collection terminal is written. Through the combination of home local area network and cloud platform, the real-time view of camera shooting information is realized at the web end of mobile phone, and the real-time viewing of the situation in the home is realized.The mobile phone APP realizes the real-time monitoring of sensors, including infrared detection of human body and flammable gas detection, and realizes the control of household appliances through mobile phone.The main innovation of this paper is to apply the first single-chip wireless microcontroller, SinpleLink Wi-Fi CC3200, which is newly developed by TI Company, to the design of smart home.And using the Yeelink cloud and APP to monitor and control the home appliance. CC3200 in real time on the mobile phone as one of the biggest bright spots.It is the first single chip microcontroller unit with built-in WI-FI connectivity, which integrates the wireless MCU with high performance ARM Cortex-M4. It is composed of WI-FI network processor and power management subsystem.This paper studies the parameter specifications and technical characteristics of CC3200, designs the corresponding peripheral circuits, and designs the hardware and software of the smart home wireless security system based on the background of home local area network and the cloud platform.The realization of wireless security system based on CC3200 is completed, including wireless video surveillance system, infrared sensor security alarm system, combustible gas monitoring and alarm system and integrated home intelligent system.Realize the real-time monitoring and control of home appliances.On the other hand, in the design, the CLOSED state is removed and it is in the LISTEN state at the beginning to listen for the connection request of the client, avoiding the active or passive open operation, so it is more efficient in the embedded situation.
