The Research Of Wireless Voting System Based On NRF401

At present,there are a lot of voting activities in deciding on awards through discussion,reviewing, competing, appraising through comparison, choosing through public appraisal, andbidding. The commissions mostly write the results on paper via current voting methods. Theresult is counted artificially, which demands very long hours. The traditional voting methodshave disadvantages not only in: spending of time, computing mistakes, taking a lot of time,but it is also hard to tackle and unbelievable. Adopting the electronics accounts, the scorewith statistics can be realized in time and the computing mistakes will not happen. Moreover,to overcome the weaknesses of the method voting in network machine room, we adopt theway of the wireless voting, so time and location can be unrestricted. The new system savestime, operates easily, resulting in creditable counting, and has advanced applications.Economic performance and social performance are obvious, and it has a wide application.The main purpose of this subject is to realize the system. Key research includes:development of wireless communication module in short range based on nRF401;Thesystematical design and realization of the handy machine with integration of the liquid crystaldisplay and keyboard;Its core contents involves hardware design of wireless communicationmodule in short range, design and realization of communication protocol etc.The booming development in system of wireless communication modular in short rangedestines the trend of the combination between short distance communication skills andapplications. The application in voting system is rising. This system has its owncommunication protocol which is fast, safe and fine. The experience can be widened to theresearch of wireless sensor network.This text expatiated the meaning, working principle, basic construction and the maindifficulty in the technique of the wireless voting system. And the design scheme of thissystem is programmed reasonably and elaborately in the text. It studies and explains in detailthe difficulties in main technique. Moreover, it designs and realizes the system and it mainlyconcentrates on research and design of handy machine and wireless communication module.
