Abstract

This invention relates to a electronic chessboard. A radio-wave frequency transmitter and a receiver are provided under each chessman position of chessboard. A radio-wave frequency responder with specific code is provided within each chessman for judging characters of a chessman, such as feature, time of taking a chessman step and positions of chessman. This chessboard can time a game, record a chess manual, and show a real time game on a display directly to simulate and reproduce or transmit simulated images and data of a real time game through internet.

Description

Electronic chessboard with judgment of each piece's nature

TECHNICAL FIELD

The utility model relates to chess articles, especially an electronic chess board.

Prior art prior to the present invention

The board used in traditional chess sports has only a single swing function. The electronic board provided by Chinese patent 9202 0 7 3 6 has only position sensing. It is difficult to accurately record time according to competition rules for timekeeping. The wrong actions of chess pieces, translation pieces, etc. cannot be correctly judged, so it is difficult to realize the functions that an electronic chessboard should have.

Object of the invention

The purpose of the utility model is to provide an electronic chessboard which can accurately record a match according to the rules of the match. . Technical Solution of the Invention

The technical solution of the utility model is composed of a chessboard, chess pieces, a microprocessor, and a display device, and is characterized in that: a radio frequency transmitting and receiving device is arranged below each chess point of the chessboard, and each chess piece is equipped with a specific one corresponding to the nature of the chess piece. A coded radio frequency response device, each transmitting and receiving device is connected to a logic coding circuit, and the logic coding circuit is connected to a microprocessor.

Advantages of the utility model: 1. It can directly perform automatic timing and notation, and give a prompt alarm to the number of players, so as to avoid affecting the normal performance of players; 2. It can directly simulate or reproduce the game on the display device in real time or pass The internet transmits real-time simulation images and data of the game.

BRIEF DESCRIPTION OF THE DRAWINGS.

The present invention is further described below with reference to the drawings.

FIG. 1 is a schematic structural diagram of a chessboard piece of the present invention;

FIG. 2 is a schematic diagram of the present invention;

Figure 3 logic coding circuit diagram;

Figure 4 Block diagram of the microprocessor connection.

In FIG. 1, a chessboard surface 11, a position sensing plate 12, a radio frequency transmitting and receiving chip 1 3, a chess piece 2, and a transmitting chip 21 are provided. A position sensing board 12 is hidden under the chessboard surface. Each position of the chessboard in the position sensing board 12 has a radio frequency transmitting and receiving chip 1 3, and each of the chess pieces 2 contains a specific code corresponding to the nature of the chess piece. Transmitting chip 2 1. Each RF transmitting and receiving chip 1 3 is connected to the microprocessor The device sends the current position to the microprocessor, and the specific code of the chess is sent to the microprocessor, and the microprocessor can determine what chess is at each position.

Examples

1. A radio frequency response chip is embedded in the lower part of the chess piece, which does not change the appearance and feel of the chess piece.

2. A pager chip is buried under each move. The answer chip in the tongue is PCF7930 or 7931 of PHIPS, and the pager under the checker adopts the corresponding base station IC for PHIPS MFCM200. (Base station IC sensing distance is 20mm) The schematic diagram is shown in Figure 2.

The unified logical arrangement of each move is performed, and the base station IC reads and writes the 7930 or 7931 to realize the judgment of the presence or absence and the nature of the pieces at each move.

3. The logic coding circuit is shown in Figure 3. An example of 90 points (Chinese chess) is given. The principles of international chess and Go are similar, except that the number of detection points is different.

Because the response chip is not programmed, the data input line of the base station IC is shielded, and the data output line is connected to the output end of the multi-channel analog switch. The microprocessor provides address coding for the decoding circuit and the multi-channel analog switch, and selects a channel. Analog switch, the output end sends the data read by the base station IC to the serial port of the microprocessor for processing. In the picture: IC7 (74HC244) is a bus driver, used to improve the load capacity. IC1-IC6 is a 16-bit analog switch 4067, which can form 6 X 16 = 96 multi-input, one-output multi-switch (only 90 is used here). The 8-bit address line is provided by the microprocessor.The lower 4 bits of the address are connected to the encoding end (S0, Sl, S2, S3) of each 4067 through the 244 driver.The lower 3 bits of the upper 4 bits are connected to 3 respectively. The outputs Y0-Y5 of the encoder A, B, and C decoders of the 8-bit IC8 decoder 138 are connected to 6 chip select terminals of 4067 respectively. The 96-channel multiplexer can be gated by 8-bit continuous code.

4. The microprocessor part is shown in Figure 4. The 51 series single-chip microcomputer is used in the embodiment. The P1 port provides continuous address coding for strobe logic coding circuit, and K) port is used as the data bus, and P0 and P2 ports are used as the address bus. For all external function circuits (such as LCD display circuit, LED circuit, keyboard, CRT) Control board, etc.) unified addressing, and the interface circuit is gated with a decoding circuit. The output end of the multiplex switch is sent to the serial port through a gate circuit, and the data is read by the microcontroller. The gate circuit is controlled to be opened by P3 and 4 terminals. Machine or modem to match the data transmission function.
