Application Of ZigBee Technology In Green Intelligent Bus

In the public building, intelligent system serves a better function on the building after the completion of the construction of great significance. Usually, in the actual project, the data transmission of intelligent system is realized through the cable transmission network. But, with the building structure more and more complicatedly, the traditional cable transmission network is relatively difficult in knob-and-tube wiring. So the wireless sensor transmission network with low power consumption, low cost and convenient installation can be added as an effective complement to the wired transmission network.In this paper, we firstly introduce the status and development of intelligent building and put forward the concept of green smart bus, and briefly analyze the basic knowledge of ZigBee technology, the protocol stack and the application in intelligent building. Secondly, the paper describes the design principle and overall structure and the design scheme on the green smart bus, also the data center, core layer and access layer of skeleton intelligent equipment network of green smart bus are configured. Then this paper introduces, in detail, the design of RF module, power module, serial communication module based on CC2430 ZigBee node hardware. At the same time, the ZigBee protocol stack software is developed by using the modular software design ideas. The paper designs the data transmission protocol and the application program of nodes, and research on the technology of ZigBee network and routing technology. Next, the design based on the ARM9 Embedded Gateway is completed by selecting TQ2440 development board as the development platform of gateway. The paper transplant the embedded Linux operating system and the boa web server and CGIC; Design the gateway and the wireless control network communication protocol, design CGI program and achieve data exchange between gateway and the wireless control network.In the end, the paper introduces the interconnection of the ZigBee communication system and intelligent equipment network through the embedded gateway, and achieves the Application of ZigBee in green wisdom bus.
