[0017] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0018] The accompanying drawings are merely schematic illustrations of the present disclosure. Identical reference numerals in the drawings represent identical or similar parts, and thus their repeated descriptions will be omitted. It will be understood that the proportions of the various components in the drawings do not constitute limitations of the present disclosure.

[0019] like Figure 1 As shown, the embodiment of this specification provides a circuit system of an intelligent electronic Go board, the system includes a main control module 1 and an infrared detection module 2 and a photosensitive detection module 3 respectively connected to the main control module 1, wherein:

[0020] The infrared detection module 2 includes an infrared emitting diode and an infrared receiving diode arranged at each chess piece placement position on the chessboard. The infrared receiving diode is used to detect the emitted light of the infrared emitting diode reflected by the chess piece and generate a corresponding electrical signal to feed back to the main control module;

[0021] The light-sensitive detection module 3 includes a light sensor and multiple photodiodes. The light sensor is used to detect ambient light to form a reference signal. Multiple photodiodes are respectively set at each chess piece placement position on the chessboard. They are used to detect the ambient brightness when there is no chess piece blocking the light, or to detect different ambient brightness when blocked by different types of chess pieces.

[0022] The main control module 1 is used to judge whether there is a chess piece on the corresponding position of the chessboard according to the electric signal fed back by the infrared receiving diode, and to judge the type of the chess piece according to the ambient brightness and the reference signal fed back by the photosensitive diode and the photosensitive sensor.

[0023] The system further comprises an LCD module 4 connected with the main control module, which is used to simulate and display the situation of the chessboard under the control of the main control module 1. In this way, the whole chess process can be recorded on the screen synchronously, which is convenient for the audience to watch and for the players to review and learn after the game.

[0024] Specifically, when the infrared detection module 2 is working, as shown in the figure, Figure 2 the infrared emitting diode D3 emits infrared light, the resistor R5 is used to adjust the intensity of the emission, the infrared receiving diode D4 receives the reflected light, and the resistor R6 is used to adjust the receiving sensitivity. When the chessboard has no chess piece, the infrared receiving diode D4 is in a high resistance state, and its output end SIN0 is at a low level. When the chessboard has a chess piece, the infrared receiving diode D4 receives the signal from the infrared emitting diode D3, and then SIN0 is at a high level, thereby achieving the purpose of detecting whether the chess piece has fallen. The detection distance can be controlled by adjusting the emission resistor R5 and the receiving resistor R6.

[0025] As shown in the figure, Figure 3 the photosensitive sensor CON1 is used to check the brightness of the environment, thereby achieving the purpose of compensating the photosensitive diode. The photosensitive sensor with model STK3311-X is used to check the real-time brightness of the ambient light, and the main control module uses I2C communication. This value is a reference value, which can compensate the photosensitive diode.

[0026] As shown in the figure, Figure 4 the photosensitive diode D1 is used to judge whether it is a black chess piece or a white chess piece. A photosensitive diode needs to be placed at each place where the chessboard falls. The principle is that the light transmittance and brightness reflection of black chess pieces and white chess pieces are different. The voltage detected by the photosensitive diode D1 also has a difference. The impedance of the photosensitive diode changes according to the change of the brightness. The brighter the brightness, the greater the current passing through the photosensitive diode, and the higher the voltage collected. When starting, the brightness value of the photosensitive diode is synchronized through the photosensitive sensor. When there is no chess piece, the brightness value is set as A1. When a white chess piece is placed, the photosensitive diode at the chess piece position will feel a certain change in brightness, so the collected voltage will be lower than that when there is no chess piece, and the brightness value is set as A2. When a black chess piece is placed, the photosensitive diode at the chess piece position will feel a greater change in brightness than that of the white chess piece, so the collected voltage will be lower, and the brightness value is set as A3, thereby achieving the purpose of distinguishing black chess pieces and white chess pieces.

[0027] Photosensitive diodes and infrared emitting tubes are used to detect chess moves and distinguish between black and white chess pieces, avoiding mixing of chess pieces on the board. At the same time, the entire chess-playing process can be recorded by the main control module, making it easy to review and learn after the game is completed. Compared with the design of magnetic chess pieces and chessboards, the technical solution disclosed in this disclosure has lower costs and is more in line with the gaming habits of the flag bearers.

[0028] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in this disclosure.
