Abstract

The utility model relates to an appliance in the class of chess, particularly an electric chessboard. The utility model is characterized in that the lower part of every chess piece putting point of the chessboard is provided with a radio frequency emitting and receiving device; every chess piece is provided with a radio frequency answering device for specific codes corresponding to the quality of chess pieces inside. In this way, the utility model can accurately judge every chess position having a chess piece or not, the quality of the chess piece, and the time and the position of chess proceeding. The utility model has the advantages that the utility model can correctly, directly, and automatically time and record chess manual; competitions can be directly simulated and reproduced in real time on a display device; or simulation images and data of competitions can be transmitted in real time through Internet.

Description

Electronic chess-plate with each chess piece character judgement

The utility model relates to chess articles for use, particularly electronic chess-plate.

The chessboard that traditional chess game is used has only single pendulum chess function, and the electronic chess-plate that Chinese patent 90200736 provides, has only location sensitive, be difficult to exactly by rules of contest record for clocking, and to carrying out chess piece, the misoperation of translation chess piece etc. can't correctly be judged, so just is difficult to realize the due function of electronic chess-plate.

The purpose of this utility model be to provide a kind of can be by the electronic chess-plate of rules of contest accurate recording match.

The technical solution of the utility model is: be made up of chessboard, chess piece, microprocessor and display unit, it is characterized in that: a radio-frequency transmissions and receiving system are equipped with in each bottom of playing chess of chessboard, the radio-frequency response device of one specific coding corresponding with chess piece character is housed in every chess piece, each emission and receiving system connect a logic coding circuit, and logic coding circuit connects microprocessor.

Advantage of the present utility model: 1, can directly carry out self-clocking, note spectrum, and point out warning, avoid influencing the normal performance of player's level to row chess player number; 2, can directly match real-time Simulation on display unit be reproduced or transmit in real time analog image, the data of match by the internet.

Further specify the utility model below by accompanying drawing.

The structural representation of Fig. 1 the utility model chessboard chess piece;

Fig. 2 schematic diagram of the present utility model;

Fig. 3 logic coding circuit figure;

Fig. 4 microprocessor connects block diagram.

Among Fig. 1, chessboard surface 11, position inductive disks 12, radio frequency emission and receiving chip 13, Chess piece 2, transmitting chip 21. Keep a position inductive disks 12 below the chessboard surface, the position induction Each of coiling 12 interior corresponding chessboards played chess a little radio frequency emission and receiving chip 13, and each The transmitting chip 21 of one specific coding corresponding with chess piece character is housed in the chess piece 2. Each radio frequency Emission and receiving chip 13 all are connected to microprocessor, one's own department or unit are equipped with no chess, the specific volume of chess Code send microprocessor, microprocessor just can judge to play chess each that chess is a little arranged what chess be.

Embodiment:

1, presses the chess piece bottom and embed a radio-frequency response chip, do not change the outward appearance and the feel of chess piece.

2, bury a pager chip in each bottom of playing chess.Reply the PCF7930 or 7931 that chip adopts PHIPS in the chess piece, the respective base station IC MFCM200 of the pager employing PHIPS under playing chess a little.(base station IC distance of reaction is 20mm) schematic diagram such as Fig. 2.

Carry out unified logic layout under playing chess a little to each, carry out read-write operation to 7930 or 7931, can realize that each is played chess to go up a little that having or not of chess piece judged and character judgement by base station IC.

3, logic coding circuit as shown in Figure 3, that provide is 90 some embodiment (Chinese chess), chess, go principle are similar, and is only different in test point quantity.

Owing to do not carry out programming operation to replying chip, Data In-Line shielding with base station IC, DOL Data Output Line is connected on the output of multiway analog switch, microprocessor provides geocoding to decoding circuit and multiway analog switch, the a certain path analoging switch of gating, the data that output reads base station IC are delivered in the serial port of microprocessor and are handled.Among the figure: IC7 (74HC244) is a bus driver, in order to improve load capacity IC1-IC6 is 16 analog switches 4067, the multichannel that can form 6 * 16=96 road is imported the variable connector (only using 90 tunnel here) of one tunnel output, 8 address wire is provided by little processing, low 4 bit address are received every 4067 coding side (S0 by 244 driving, S1, S2, S3) low 3 coding side A that are connected on 3-8 position IC8 decoder 138 respectively in high 4, B, the sheet choosing that the output Y0-Y5 of C decoder is connected on respectively 6 4067 is held, and No. 96 variable connectors can be by 8 continuous coding gatings.

4, microprocessor portion as shown in Figure 4: what adopt among the embodiment is 51 series monolithics.Provide continuous geocoding in order to the gate logic coding circuit by the P1 mouth, the P0 mouth is as data/address bus, P0 mouth, P2 mouth are as address bus, to all external functional circuits (as LCD display circuit, led circuit, keyboard, CRT control panel etc.) unified addressing, with decoding circuit gating interface circuit.The output of variable connector is delivered to serial ports through a gate circuit, by the machine-readable personal data of monolithic, this gate circuit is opened by the control of P3,4 ends, and serial communication port is connected to level shifting circuit (232 or 485), can realize the function of data transmission with host computer or modem mutually.

Claims

1, a kind of electronic chess-plate with each chess piece character judgement, it is made up of chessboard, chess piece, microprocessor and display unit, it is characterized in that: a radio-frequency transmissions and receiving system are equipped with in each bottom of playing chess of chessboard, the radio-frequency response device of one specific coding corresponding with chess piece character is housed in every chess piece, each emission and receiving system connect a logic coding circuit, and logic coding circuit connects microprocessor.
