【摘要】：随着电子技术的发展和无线局域网的演进,越来越多的嵌入式产品具备了以无线的方式接入Internet的功能,实现了网络资源的共享,并为用户提供更加人性化的服务。这种智能化和网络化的嵌入式产品深受广大消费者的喜爱,显然已经成为了新的发展趋势。本文正是在上述背景和需求下,设计并实现了一种将嵌入式控制技术、WiFi无线网络技术、Internet技术和Android技术相结合的智能家居远程监控系统。提出的解决方案对于智能家居和远程监控领域的研究具有较高的借鉴价值。本文选择了ARM Cortex-M3内核的32位微控制器STM32F103RET6,WiFi无线网络模块、图像采集模块和其他必要的控制电路共同构成了智能家居监控系统的硬件平台。软件部分的设计涉及的内容比较多,也是本文研究的重点和难点。嵌入式控制系统要实现无线接入和设备监控,首先需要WiFi模块的驱动程序、图像采集程序和其他功能控制程序的支持。在此基础上移植嵌入式TCP/IP协议栈Lw IP,赋予监控系统访问Internet的功能。最后基于HTTP协议设计了嵌入式主控系统的应用程序,把家居设备的传感器信息和监控图像同步存储到云端的Web服务器。本课题还针对当前最流行的Android智能手机,设计了一个功能实用、操作简单的远程监控APP。Android手机通过3G/4G/WiFi等网络与云端服务器相互通信,而云端的服务器通过Internet和WiFi网络又与家中的各种传感器相互通信,从而间接地实现了对各种智能家居设备和监控图像的访问与控制。在嵌入式主控端和手持终端分别对系统进行测试,结果表明系统运行稳定,各个功能模块工作正常。Android应用软件操作灵活易用,大大方便了用户对家居设备进行远程监控。整个系统的功能性和稳定性基本达到了预期的任务要求,这样的解决方案具有较高的实际使用价值。
[Abstract]:With the development of electronic technology and the evolution of WLAN, more and more embedded products have the function of wireless access to Internet, and realize the sharing of network resources. This intelligent and networked embedded product is deeply loved by consumers and has obviously become a new trend of development. This paper designs and implements a kind of intelligent home remote monitoring system which combines the embedded control technology WiFi wireless network technology and Android technology. The proposed solution is of great importance to the research of intelligent home and remote monitoring field. This paper chooses the 32-bit microcontroller STM32F103RET6WiFi wireless network module of ARM Cortex-M3 kernel. The image acquisition module and other necessary control circuits constitute the hardware platform of the intelligent home monitoring system. The embedded control system needs the driver of WiFi module to realize wireless access and device monitoring. On this basis, the embedded TCP/IP protocol stack LW IPs is transplanted to enable the monitoring system to access the Internet. Finally, the application program of the embedded master control system is designed based on the HTTP protocol. The sensor information and the monitoring image of the home device are stored synchronously to the Web server in the cloud. This subject also designs a practical function for the most popular Android smart phone. Simple remote monitoring of APP.Android phones communicates with cloud servers via networks such as 3G / 4G / WiFi, while cloud servers communicate with sensors at home via Internet and WiFi networks. Thus the access and control of various smart home devices and monitoring images are realized indirectly. The system is tested on the embedded main control terminal and the handheld terminal respectively. The results show that the system is running stably. Each functional module works normally. The Android application software is flexible and easy to use, which greatly facilitates the user to remotely monitor and control the home equipment. The function and stability of the whole system basically meet the expected task requirements. Such a solution has a high practical value.
