Studies And Designe Of The Control System Of The Smart Home Based On Bluetooth

With the development of science and technology, and the improvement of people's living standards, people are paying more and more attention to the comfortablity, safety and convenience of their living environment. The emergence of smart home system in recent years, just meets the needs of people. It effectively constitutes appliances into a home information network and makes all kinds of appliances combined into an organic whole. It can intelligently control appliances locally or remotely, and exchange information with the outside world.Firstly, after comparing variety of networking technology within home, and studying of the application of Bluetooth serial part profile (SPP) and the Communication protocol specification of home control sub-network, the implementation scheme of home control sub-network based on Bluetooth is proposed. According to actual application fields, the communication protocol architecture for this scheme is established by using universal device control protocol (UDCP) over SPP and it becomes easier when the home control sub-network is networkedSecondly, the design of smart home controller, which is at the core of smart home system's implementation, is studied and realized in both software and hardware. On the hardware side, Samsung's S3C2410 chip (ARM9) is selected as the main CPU of the intelligent home controller, which is with good performance and low price. The power supply, display, input, storage, wireless Bluetooth and GPRS module circuits of smart home controller are designed. On the software side, U-boot, embedded Linux kernel and BlueZ (Bluetooth protocol stack) are implanted to the target board successfully. Then each hardware module's driver of the system is added into the Linux kernel.Finally, Bluetooth modules'communication, which is point to point, is tested. And some common and useful GUI is designed. The research is summed up and the implementation of the research and other functions of the intelligent control system to implement are listed out.
