Portable Smart Home Control Terminal Based On ZigBee

In the background of the rapid development of science and technology, people put forward new requirements on the quality of life:intelligent, humane, high-tech and so on. The smart home emerged as the times require, to meet the needs of people, and to bring people’s lives a whole new experiences and feelings. Smart home will be a part of wonderful chapter in our lives, so it will become the trend of family life and will be the trend of development in the future.The system combines ARM technology and ZigBee technology, aiming at portable control life at home, through the LCD touch screen to achieve the purpose of controlling the operation of the family appliances.First and foremost, which wireless technology is selected in the indoor environment. Comparison the pros and cons of short-range wireless transmission, we can find the appropriate wireless technology of the indoor. Also use ARM technology and Linux operating system, this is the first work to be done. Next, according to the functional design of the system to achieve the overall block diagram, the hardware plat forms including ARM circuit and ZigBee circuit. According to the functions of different sub-module design of the circuit, the system is set up to complete the circuit of the total figure.Then, the task is the development and debugging of software. Hardware circuit as a platform, according to the module debugging software, hierarchical functional design is completed. Firstly, ARM and ZigBee platforms working together. ARM platform is the foundation, and ZigBee platform is the key. The ARM platform completes the transplantation of the Linux operating system and Qt graphical interface design. The ZigBee platform achieves wireless transmission of data and the node control functions.Finally, ZigBee nodes and ARM platform tested jointly. LCD touch screen not only is used as a indicator displayed the data from the transmission of ZigBee, but also is used as a controller controlled the working conditions of the ZigBee nodes.Joint test results show that the system can achieve appliance controlling, security alarming, indoor environmental monitoring and kitchen appliances controlling, to achieve the desired effect. Research on the development of the future smart home plays a promotional role and designs reference help in the future of smart home.
