Electronic Go chessboard

Abstract

The invention discloses an electronic Go chessboard. The electronic Go chessboard comprises a chessboard body, and also comprises a central control circuit, a Go playing indicating circuit, a Go playing identifying circuit and a voice circuit, wherein both the Go playing indicating circuit and the Go playing identifying circuit carry out I / O port extension on the basis of line-rank scanning to complete control over Go playing position indicating lamps and an induction circuit, the circuit structure is simplified, the circuit ability is improved, and the manufacturing cost is reduced accordingly; in the Go playing indicating circuit, through the four Go playing indicating lamps, the locking speed of Go playing positions is increased, and emergency capacity is enhanced; rapid and accurate chess-piece state identification is achieved through the Go playing identifying circuit and characteristics of a resonance circuit and structural design of chess pieces.

Description

technical field [0001] The invention belongs to the technical field of an electronic Go board, in particular to an electronic Go board. Background technique [0002] Go is a strategic board game for two players. It was called "Yi" in ancient China and "Go" in the West. Popular in East Asian countries (China, Japan, Korea, etc.), it belongs to one of the four arts of "Qinqi, Calligraphy and Painting". [0003] Go uses a square lattice board and black and white two-color circular chess pieces to play games. There are 19 vertical and horizontal lines on the chessboard to divide the chessboard into 361 intersections. The one with the most siege wins. Ancient Chinese go is that black and white sides place two pieces (diagonal star layout) respectively at the diagonal star positions, and the white chess goes first. Modern Go was developed from Japan, and the rule of the seat was canceled, black first and white later, which made the changes of Go more complex and changeable. Go...

AI Technical Summary

Problems solved by technology

[0008] Using photoresistors, install photosensitive elements on the 361 chessboard positions respectively, and use the light that the chess pieces cover the chess positions when the pieces are placed to identify whether there are pieces. This method is relatively simple and the cost is low, but there are 2 Fatal flaws: 1. Can only identify black and white pieces, but cannot identify black and white pieces; 2. It will be interfered by ambient light, the surrounding environment should not be too bright or too dark, and it will also be affected by the shadow of the player's arm when playing chess;

[0009] Using magnets, install magnetic sensitive elements on the 361 positions on the chessboard, embed magnets in the chess pieces, and use the north and south poles of the magnets to identify the state of the chess pieces. This method can identify black and white pieces, but it also has fatal shortcomings: 1. Chess pieces need to be embedded with magnets, which will attract each other, and because the magnetic field lines of the magnets have a large range, it will seriously affect the recognition of chess pieces adjacent to chess positions, and the user experience is not good; 2. It is difficult to ensure the consistency of the magnets embedded in the chess pieces. Affect the reliability of chess piece identification; 3. The cost of magnetic sensitive elements is relatively high, resulting in a high overall cost of the chessboard;

[0010] Using RF radio frequency card chips, the RF radio frequency card chips of the black and white chess pieces are respectively written with unique identification codes, and an RF radio frequency card reader is embedded in each of the 361 chess pieces on the chessboard, and the card is read by the RF radio frequency card. The device reads the unique identification code of the chess piece to identify the state of the chess piece. This method can realize the identification of black and white pieces, but there are also disadvantages: 1. The cost of the RF radio frequency card chip and the RF radio frequency card reader is too high, resulting in the overall cost of the chessboard. 2. Each chess position is embedded with an RF radio frequency card reader, and the surface of the electronic Go board has 361 chess positions, which makes the overall production process of the chess board very complicated
