Chess board with automatic notation

Abstract

The invention belongs to the technical field of checkerboards, and discloses a chess board with automatic notation. The chess board with the automatic notation comprises a checkerboard induction module, a radio frequency module, a data acquisition module and a storage module. The checkerboard induction module is used for detecting and recognizing checkerboard coordinates and touch positions of chess pieces through a checkerboard sensor installed. The radio frequency module is used for obtaining analog electrical signals of the positions of the chess pieces and transmitting the analog electrical signals to the data acquisition module, and active RFID information labels of the radio frequency module are embedded into each chess piece for sensing the positions of the chess pieces. The data acquisition module is used for converting the analog electrical signals obtained by the radio frequency module and the checkerboard induction module into digital signals and sending the digital signalsto a master control module. The storage module is used for storing location information of the chess pieces. The chess board with the automatic notation can accurately and relatively position transponders at different positions. According to the variation trend of return signal intensity, a maximum value of the signal intensity is found and the distance between a reader and the transponders is obtained according to the maximum value, so that relative positioning of the transponders can be performed accurately.

Description

technical field [0001] The invention belongs to the technical field of chessboards, in particular to a chessboard with automatic notation. Background technique [0002] Chess, also known as chess, is a board game played by two players. The chessboard is a square, consisting of 64 black and white (dark and light) grids; the chess pieces are divided into black and white (dark and light) sides with a total of 32 pieces, each with 16 pieces. Although it is called Western Chess or Chess in Chinese, it actually originated in Asia and was introduced to Europe by the Arabs. It became an internationally popular chess game, and it is also an intellectual competitive sport. It was once listed as an official event of the Olympic Games. . [0003] Within a certain range, how to quickly find and accurately locate the transponders that identify key facilities in chess pieces and read their ID information is a problem that must be solved. The core application of traditional RFID is to re...
