Research And Design On Wireless Bridge Bidding And Scoring System

With the continuous improvem ent of qua lity of life, the requirem ents of entertainment comfort and convenience ar e increasingly high. How t o improve the fairness and intelligent of bidding and scoring in the bridge gam e, has become a widely concerned topic of a lar ge number of bri dge game professionals and enthusiasts. Because of the lack of tim e and remind function, or the improper of its communication mode, the existing solutions have not been ap plied to the bridge gam e. In view of the above shortcomings, this paper designed a "bridge bidding and scoring system based on ZigBee wireless communication technology". Th is system can solve the problem s of bidding and scoring in bridge gam es, and th e fairness and intelligence will also b e ensured. According to the func tional requirements and technical characteristics of the system, the main content of this paper includes the following three aspects:(1) The overall design of bidding and scori ng system. This part includes wireless communication module, bidding module, scoring server module. And according to the characteristics of the system choose ARM se ries microcontroller STM32 as the core processor, the corresponding hardware circuit diagram is designed according to the function of each module.(2) ZStack agreement of ZigBee wireless communication technology is researched. And by selecting the tree topology structure according to the demand of the system, the wireless networking and data transmission f unction was realized. In order to guarantee the high connectivity of network system, the wireless sensor network connectivity problems were studied in th is paper, and the related simulation experiments were completed.(3) Scoring system server was builded by using MFC fra mework. Data transmission between server and wireless network was realized through RS232 serial port and the data is stored in a MySQL data base. When the game is finished, the score will be calculated and transmitted to each term inal node of this wireles s network through the serial port.In the paper’ s final, the f unctions of the system are te sted in th e experimental environment, including wireless network of system, communication function, the serial communication function, the m odule function, score server and so on, and then reliability of the system is verified.
