Design And Implementation Of Terminal System For Intelligent Building Based On Embeded Linux

With the development of social information process, the people are not only concern about room area, natual environment and traffic situation around living community and so on, but also put more interest and attention on the aspect of outside communitcation, information service,security guard,estate management. This system provides the visual talk-back capability between the tenement and the caller, reduces the receive time and monitor circumambience. Recently, the design and implementation of intelligent building terminal system is attaching importance.This paper brings forward the design idea to hang together the web browser and visual talk-back. It uses fashionable ARM9 platform and Linux operate system, and use the network which joins the intelligent terminal devices to implement all the function, which is in use this system has many advantages such as convenience in function extension, not expensive, easy to install, and convenience of maintaining. The browser makes the user much easy to get the information from server, as the demand of water and electricity charge; the video talk-back which based on web is more convenient for the communication of the tenement and the caller, and can control the switch of the electron door.Puts forward the point to add UDP monitor module in intelligent terminal and transmit special UDP command datagram, it can deal with intelligent terminal call request, receive video call, send open door or refuse commend, show the choose status to the user and induct the correlative operation. This measure has the advantage of low bandwidth, fast transmission, depress coding complexity.By our test, this system runs stably, the browser can capture special information and the video talk-back works fluent.
