Abstract: Aiming at the limits of wired deployment, node interference, transmission bottleneck etc in the present voting system, an intelligent wireless voting system based on the technology of radio frequency identofication(RFID) and RS485 bus was organized. The system scheme, hardware and software were discussed in detail. By applying the multi-level distributed architecture to achieve the high data acquiring, handling and displaying simultaneously, the XXTEA encryption and decryption algorithm was embedded in the communication link to ensure the security of the dates transmission. Results of experiments verified that the system has merits of low power, high reliable, low cost and easy to use and install, and its overall performance and each index are feasible.
Key words: wireless voting system; radio frequency identofication(RFID); XXTEA algorithm
