[Abstract]:With the development and progress of science and technology, people need to improve the quality of life increasingly. Home as an essential part of daily life, gradually become the focus of attention. Xiaomi Technology founder Lei Jun at the World Conference on the Internet published "Smart Home to lead the Future World". This paper presents a new mode of Internet of things home which combines intelligent hardware ecological chain with software and Internet around Xiaomi mobile phone. It can realize the data of life and data modeling in the future. Model production is the ultimate goal of the Internet of things home. Today's Internet of things technology, computer technology. The communication technology and sensor technology lay a solid foundation for the development of the Internet of things home. Based on the previous research, according to the task requirements of China Electronic Panda Group Internet of things home high-tech project. This paper studies and implements a kind of Internet of things home system based on android, which includes client and intelligent gateway unit. Wireless sensing network unit three parts. Client application through the TCP/IP protocol to achieve the control of the Internet of things home system. Intelligent gateway unit as the core part of the home network to achieve network access. Remote alarm and wireless connection sensing network unit. Wireless sensing network unit to collect data and communicate with intelligent gateway unit through serial port. When in a state of emergency. The intelligent gateway unit can send information to the client through GSM module to realize the function of remote alarm. According to the requirement of hardware and software of wireless Internet of things home system and the contrast analysis of the mainstream communication mode. Cortex-A8 processor is chosen as the hardware platform and Android operating system as the software platform. Zigbee technology as a means of wireless communication, TI AM335x as the main control chip with extended circuit as the gateway. CC2530 series of zigbee modules to build a wireless awareness network. Between the mobile phone client and the gateway. This paper analyzes the process of transplanting and clipping the kernel of android 4.2 system on the hardware platform of gateway, completes the programming and debugging of gateway server, and aims at the security of LAN data communication. Using the principles of protocol connection, session, handshake, secret level transformation, this paper adopts SSL protocol encryption technology in connection and data transmission between client and gateway, and gives the implementation of hierarchical encryption technology. Between gateway and wireless sensing network, the corresponding circuit module based on TI CC2530 development board is designed, including RGB lamp control circuit. Motor switch control circuit, intelligent socket circuit and so on, and based on zigbee Z-stack protocol stack for secondary development. The design of the android based on the Internet of things home system, the main realization of the user needs of the temperature and humidity environment awareness, kitchen smoke alarm, home appliances control. Intelligent control of RGB multi-color lamp and motor curtain. The classified encryption method used in the system effectively ensures the safety and reliability of the system and brings convenience to the user's life.
