Based On Bluetooth Technology, Smart Appliance Network System

With the improving of people' s incomes and science technology level of the world, the home electronic appliances have been changed from expensive and durable consumables to diffusive consumables. The quantity and the types of home electronic appliances, which have entered the general families, are increasing. How to let the users manage all kinds of these home electronic appliances easier and more effective has become a problem that people must face. From the late 90' s of last century, many kinds of short-range wireless communication technology standards have emerged. Among them, the Bluetooth Technology has been applied to some small digital terminators because of its low power consuming, high security and low price compared with other short-range wireless communication technology. The goal of this paper, is to research one kind of intelligent electronic appliances network which has the following characters: The connection between the electronic appliances or between the electronic appliance and the Internet is realizable; the operation methods of all kinds of electronic appliances which locate at home, can be set by the user through the PCs at home or outside home which can access to Internet; the electronic appliances can acquire the information and the services from the Service Provider Web Stations automatically when the operations is required; the new composed electronic appliances network or the electronic appliances which are just to join the network, can be "Plug & Play" without user' s setting, the electronic appliances themselves accomplish all the settings. This paper realize the intelligent electronic appliances' functions of composing network, acquiring information and services, through combining the Bluetooth Technology' s "Service Discovery Profile" "Serial Port Profile" and "LAN Access Profile" into the profiles of special electronic appliances, using the platform-independent language Java towrite the programme of application software, adopting Sun' s J2EE technology standard to design the simulated Service Provider Web Station and realize its functions of providing information and services. The result of the experiments proved that, the design requirements of intelligent electronic appliances network based on Bluetooth Technology could be fulfilled completely. The system has good stability and practicability. The Bluetooth Technology and the intelligent electronic appliances network, are still on developing and perfecting, how to make them be compatible with each other is the key question of whether they all will develop successfully in the future, it deserves being researched continually.
