| I-go has a long history in our country. A lot of people are fond of playing I-go. With the developing of society, people have a higher demand on live broadcast of I-go, but nowadays live broadcast of I-go almost are display by commentator, real-time is not good, it can not satisfy I-go game fans. Based on above viewpoints, a new electronic I-go board is introduced in this paper.According to current condition, the paper summery current method and design a set of I-go matrix analog signal acquisition and real-time display system. Motion of I- go pawns and the signal acquisition are detailed analysis and research, I present my own views. The whole I-go board is composed of 19 lines in x direction and 19 rows in y direction which forms a two dimensional matrix. So there are totally 361 intersections in this I-go board. And every intersection has three status: black, white and none. The key is choose which one of intersections, and recognize what status this one is. PIC16F876 MCU is core module of this data acquisition system as main controller. The cheap photosensitive resistances are used as the sensors of I-go pawns'status. As photosensitive resistance has a high distinguish for black white and none, good at recognize the I-go pawns'status, then save data in RAM. MCU communicate with computer by RS-232 serial communication interface. In computer software design, we should consider certain natural factors and factitious factors and eliminate interference. And every step of the match process will be recorded by system, in case we can review after the match.Field test results show: the I-go matrix analog signal acquisition and transmission control module processes the acquired data, and upload the data to the computer, each pawn's location of the whole I-go board display on the computer screen accurately by computer software design to achieve a real-time monitoring and real-time display purposes. |
