Based On The Zigbee Wireless Mobile Conference Voting System

With the development of society, a variety of information is getting more and more. People have to speed up the processing speed of the information. Nowadays, team cooperation is increasingly important to address complex issues and in order to accelerate the speed of processing information; the conference voted is on the rise. The scene arrangement of the traditional wired conference voted on is too cumbersome and inefficient; the wireless division has become an important research direction.The voting system software generally has the vote function, but can only express one kind of situation: Agreement or opposition. This thesis has studied the existing voting system and proposed a system to support the radio type and the multi-choice type, and might carry on the next round the vote.This thesis realizes a wireless voting system based on the ZigBee technology and introduces the design of hardware, software design and WEB module. The thesis first introduced the developing process, the characteristic and the application domain of ZigBee, and then described many kinds of existing short distance wireless communication protocol. For the secure consideration, the system has designed short, the long address correspondence and the broadcast correspondence. In order to strengthen the wireless network the stability, the system design and has realized the binding data communication. In situation of many candidates, the vote tabulation is through the multi-screen demonstration, and support Chinese and English demonstration.The system has given three kind of network topology model, and may build own wireless voting machine network according to the different situation. The result information may transmit through the gateway node to PC machine, then display real-time vote information passes through the projecting apparatus. The system has carried on two kind of scene analog simulations, used for test system's drop situation, and has carried on the brief analysis, has also carried on the test for the building physical structure.
