【摘要】：随着时代的进步,人们对于居住环境的要求越来越高,一种更加舒适,安全,智能的家居体系应运而生,而计算机技术和物联网技术的飞速发展也为智能家居的出现提供了可能。本课题正是在物联网技术飞速提升的背景下提出的一种基于嵌入式的智能家居设计方案。传统的家居环境中,有线的连接方式不但占据着本就不大的生活环境的一部分空间,而且也大大影响着家庭环境的美观和安全。本文采用ZigBee无线通信的方式代替了传统的有线连接,基于互联网和嵌入式技术构建了一套智能家居设计方案。利用硬件模拟了家庭环境中的电灯、电视、空调、温度计、报警设备。而后加入了摄像头模块,使用户可以更好的掌握生活环境的动向,保证安全性。论文根据人们对于生活环境的要求以及智能家居的要求,提出了整个智能家居模型。根据当前智能家居的主流设计,以及本课题的需求,提出了使用ARM CortexTM-A8系列芯片S5PV210作为智能家居的硬件平台和嵌入式Linux操作系统作为其软件平台,搭建了整个工作环境,主要包括bootloader的移植,Linux内核的定制和移植以及Yaffs2根文件系统的构建。完成了摄像头、温度传感器、红外传感器、蜂鸣器等模块的驱动程序,用QT完成了上位机画面的制作,使用TCP/UDP完成了与下位机的通信,利用Web技术使用户可以在移动端如手机、平板登陆站点查看摄像头传回的实时家庭环境以及控制智能家居系统。本课题是基于ARM的嵌入式智能家居系统,使用了 ZigBee无线通信代替了传统的有线设计,解决了家庭安全隐患的同时还使其变得更为美观;加入了摄像头模块,满足了人们对于家庭周围的全方位监控,使生活环境更加安全;使用了 QT完成了上位机画面的制作,使得人机交互界面更为友好,移植性更强。
[Abstract]:With the progress of the times, people have higher and higher requirements for the living environment, a more comfortable, safe, intelligent home system emerged as the times require. The rapid development of computer technology and Internet of things technology also provides a possibility for the emergence of smart home. This topic is a kind of intelligent home design scheme based on embedded system under the background of the rapid improvement of Internet of things technology. In the traditional home environment, the wired connection not only occupies a part of the living environment, but also greatly affects the beauty and safety of the home environment. This paper uses ZigBee wireless communication instead of the traditional wired connection, and constructs a set of smart home design scheme based on Internet and embedded technology. The electric lamp, TV, air conditioning, thermometer and alarm equipment in home environment are simulated by hardware. Then added camera module, so that users can better grasp the trend of the living environment, to ensure security. According to the requirements of living environment and smart home, the whole model of smart home is put forward in this paper. According to the current mainstream design of smart home and the demand of this subject, this paper puts forward to use ARM CortexTM-A8 series chip S5PV210 as the hardware platform of intelligent home and embedded Linux operating system as its software platform, and builds the whole working environment. It mainly includes the customization and migration of bootloader kernel and the construction of Yaffs2 root file system. The driver program of camera, temperature sensor, infrared sensor, buzzer and so on is completed, the picture of upper computer is made with QT, the communication with lower computer is completed with TCP/UDP, and the user can use Web technology to make the user can use mobile terminal such as mobile phone. The tablet landing site looks at the real-time home environment sent back by the camera and controls smart home systems. This subject is an embedded smart home system based on ARM, which uses ZigBee wireless communication instead of the traditional wired design, solves the hidden trouble of home security, and makes it more beautiful at the same time. It satisfies the omni-directional monitoring of the family and makes the living environment more secure. The use of QT completes the making of the upper computer screen, which makes the man-machine interface more friendly and the portability stronger.
