Research And Development Of Multi-species Compatible Intelligent Board Based On RFID

Chess games have a long history at home and abroad.Because of its simple equipment and high interesting,makes it extremely popular intellectual game.Under the guidance of high-tech,many related scientists have made significant achievements in the field of computer chess game and chess robot in recent years.The confrontation between the intelligent robots and chess masters also attracts people's attention.With the rapid development of computer chess game technology,intelligent board is developing toward the direction of electronic and artificial intelligence.This thesis designed a system of multi-species compatible intelligent board based on RFID.First of all,this thesis summarizes the development of RFID technology and intelligent board,and then analyzes the working principle,the structure and the classification of RFID system.And it puts forward a new method of piece identification.It is a piece identification of autosensing strobed based on RFID.First it detects pieces by use of Hall sensors,and then strobes the antenna module which there are changing pieces.Thereby the RFID reader identifies the information of pierces at that position.This article mainly tells the design of hardware circuit and software programming of intelligent board's lower machine.The system is composed of the underlying reading card unit based on RFID and the intermediate controlling unit based on STM32,where the underlying unit applies a modular design and transplanting embedded operating system uC/OS-II at controlling unit.And the task of software system is designed.Based on analyzing the radiation field area,the antenna working principle,the equivalent circuit and matching antenna equivalent circuit and the antenna design procedure of 13.56MHz RFID antenna,this thesis also expounds the process of establishing the parameterized 13.56MHz RFID antenna model in the Ansoft HFSS software environment.And the performance of the antenna,the influencing factors,the determination of matching circuit parameters and the coupled performance are simulated and analyzed in this antenna model.Finally,this thesis points out the shortages of the intelligent board.Through continuous improvement and experiment,the modular underlying unit can build up different chess manual which system design oriented.Combing the designing pieces,so that the system will eventually be able to achieve the function of automatic detection and recognition pieces,and it is compatible with the designing of the four kinds of chess.
