Description

The go chess tool that automatic ruling of energy and fax are played a game and composed

The utility model belongs to the invention of application of electronic technology in go chess tool.

Present go is when playing a game the match end, and the referee is entirely with artificial some order counting ruling both sides victory or defeat, and is not only time-consuming but also require great effort.Particularly, hang the chess player of deep bid explanation at home, have to mid-game situation by the match of the chess match attendant of organizing committee segmentation announcement chess when carrying out excellent great playing a game during match abroad, again with the chess manual fax of hand-kept to domestic.The time-consuming effort again of manual note spectrum, and usually careless handwriting is unclear, is subjected to the restriction of laws of the game in addition, and passing spectrum can not be timely, and explanation person brings difficulty to the extension dish.

It is investigated the improvement of a lot of people at the ancient go chess tool of research arranged recent years.For example " a kind of be used for outside the venue to show or to reappear in good time in real time weiqi play chess display " (classification number G09G3/04) adopted " by the sense of touch film accept on the chessboard/the grape signal " " eletric button go " (classification number A63F3/00) adopted be " button that can show the dichromatism hot spot is installed respectively on 361 points of chessboard; ... replace white respectively; black two look chess pieces ": what " numerically controlled ' weiqi ' and LCDs thereof " (classification number A63F9/22) adopted is " when playing chess chess; play chess chess information and imported by keyboard, chess game is shown by display screen ... "; What " flipover automatic game repeat weiqi " (A63F3/00G09B19/22) adopted is " key is that chessboard chess piece (two kinds of black and white) is an integral body ... "." a kind of go " (A63F3/02) adopted is " each is played chess a little, and a switch by chess piece control is set ... and tandem is in analog-digital converter and computer.In the position that shows chess piece on the chessboard on the computer display synchronously.”

Above-mentioned several are more representational chess tool improvement technology.But after the examination research in depth, find that these improvement technology do not possess the condition that replaces traditional chess tool fully.Because they exist obvious defects, so that be difficult to implement.Its defective mainly shows this two aspect: one, the sign and the acquisition method imperfection of chess piece information (color, position, order).Its two, do not have the joyful sense and graceful taste of son when playing chess chess.

It is the same with traditional chess tool to the purpose of this invention is to provide a kind of profile, but the joyful sense of son and the self-clocking reading the clock of graceful temperament and interest are arranged when playing chess chess, at any time the mid-game match that printing or fax is being played a game is composed, and can show victory or defeat result's go chess tool during end of match automatically rapidly.

The present invention seeks to realize like this:

Constitute profile by chess piece and common chessboard; Chessboard inside all is connected with microcomputer with bus mode with digital display circuit with printer, modem, keyboard with decoding control circuit by the information acquisition circuit combination.

Wherein, the structure of chess piece is to be embedded in permanent magnet at common stone.Make it have only the outside and South Pole (S) outside two kinds in the arctic (N),, white side information black respectively to characterize.

On the base plate in 361 crosspoints on the chessboard surface respectively over against 361 " magnetic induction switches " being installed (CN2189781Y).The magnetic information collecting unit circuit in each crosspoint is made of following described mode:

1 termination+5V of magnetic induction switch M S, 2 ends and 3 ends meet three state buffer G1 respectively, the input of G2 and C1, the anode of C2; C1, the negative terminal of C2 are connected to 4,5 ends of 74LS121, and the control end of 121 1 end and G3 ￣ G11 mutually and connect outputs to the interrupt requests end of microcomputer by phase inverter B; The 1 termination C1 of R0, the negative terminal of C2,3 ends of 2 terminations 121 of R0 and ground end; R1 connects 2 ends of MS, and R2 connects 3 ends of MS, the other end ground connection of R1, R2; 1 end of R3 ￣ R13 connects the input of G1 ￣ G11 respectively, the 2 end ground connection of R3 ￣ R13; 2 ends of R5～R13 determine to connect or do not connect+5V as required; G1, the control end of G2 are connected to an output of decoding control circuit, the corresponding connection of P2 port of the output of G1 ￣ G11 and computer.The output of phase inverter B all links to each other with the middle fracture INT of microcomputer.

The P3 port of microcomputer connects digital display and keyboard circuit.

Printer all is connected with the P4 port of microcomputer with modem.

Compare with traditional chess tool, the present invention is just the same with it in appearance, and the effect of playing chess chess is identical with taste.But relate to timing, reading the clock in play, when transmitting work such as chess manual and end time point order counting judgement victory or defeat outside the competition field, traditional chess tool is just convenient, fast far away from the present invention, accurately save time.And the go chess tool technology of new proposition recent years, or because there is defective in the chess piece information acquiring technology, or because of the change to the chess tool reduces the taste of playing chess chess too greatly greatly, the former capital is difficult to implement to promote.Owing to utilized magnetic power to penetrate these characteristics of object, so the magnetic information carrier (M) of sign color can be hidden in the chess piece (Q), the magnetic line of force penetrates chessboard when playing chess chess, and magnetic information is delivered to magnetic induction switch (MS) below the chessboard.This just makes profile of the present invention and traditional chess tool just the same.

To the acquisition mode of chess piece information, commonsense method can't be implemented.For example, X, the decoding of Y matrix, mechanical contact-type position switch etc. all makes board surface produce different " alienation " phenomenon of degree, and directly influences the taste temperament and interest of son when playing chess chess.When playing chess, do not take up, be equivalent to have on the computer keyboard a lot of keys by long connection disorderly because chess piece falls the back majority.If handle chess piece information, almost be impossible with general conventional method.This is owing to the too big reason of chess piece crosspoint information content.Each key of common keyboard has only two parameters " key position and on off operating mode ".And there are six parameters i.e. " black, white, sky, position, the sequence number of beginning, begin the time " in the chess piece crosspoint.Complexity and where the shoe pinches that go crosspoint information that Here it is characterizes.In recent years, a plurality of patent application persons formerly failed to solve effectively this difficult problem, and numerous and confused " failing " (being regarded as recalling).The present invention has been because adopted " magnetic induction switch " that can reflect outer magnetic pole (CN2189781Y) as the Primary Component of information acquisition circuit, and an above-mentioned difficult problem is readily solved.Applied Computer Techniques and modern communications technology combine with ancient chess tool and have produced modern effect, have special charming.

Figure 1 shows that theory diagram of the present invention.

Figure 2 shows that the information acquisition unit circuit in a crosspoint of chessboard.

Fig. 3 is decoding control circuit Y and chess piece Q.

Shown in Figure 4 is the working procedure block diagram.

Accompanying drawings basic functional principle of the present utility model is as follows:

Shown in Figure 1, the information acquisition circuit combination is to be formed by 361 information acquisition unit circuit set, and it is managed by decoding control circuit, finishes conversion and transmission to the chess piece information in each crosspoint on the chessboard.Decoding control circuit, printer, modem 1, keyboard all are connected with microcomputer with bus mode with the digital display circuit.

Shown in Figure 3, the inner permanent magnet (M) of chess piece (Q) is to form with the magnetic polarity tight bond by two; Promptly two South Pole are close together, and can realize externally only being the arctic (sign white side); Two arctic are close together, and can realize externally only presenting the South Pole (sign black piece).

Shown in Figure 2 is chess piece crosspoint information acquisition unit circuit, and magnetic induction switch MS is installed in each (361) crosspoint of chessboard on the base plate of answering, and it receives from the magnetic pole signal in the chess piece.When playing chess, the information acquisition unit circuit inductance is to " black, white, sky " information of chess piece.No chess piece claims " sky " when falling, magnetic induction switch no signal output this moment.When outer magnetic information arrived, 1 end was logical with 2 terminations in the MS, then obtain at 2 ends+5V level (logical one) represents that white side is on the crosspoint; If 1 end and 3 terminations are logical, then obtain at 3 outputs+5V level (logical one) represents that black piece is on the crosspoint; If no chess piece falls, then the output of 2,3 ends is its state value of 0V (logical zero) and delivers to microcomputer P2 port by G1, G2.

361 crosspoints are endowed continuous address code (000H～168H) respectively.With the end ground connection of R5～R13, another termination or do not connect+5V represents (this crosspoint) binary address sign indicating number, the buffer compartment by G3～G11 from hang over microcomputer P2 port just can be to chessboard on each address, crosspoint define.

For example, address code is that the termination of R5 ￣ R13 gets final product publicly in the crosspoint information acquisition unit circuit of 000H; And address code is the public ground of the termination of R5～R13 in the crosspoint information acquisition unit circuit of 001H, and the other end of R5 then must connect+5V; Address code is that the other end of R6 should connect+5V in the crosspoint information acquisition circuit of 002H; The rest may be inferred by analogy it, the positional information that has so solved 361 crosspoints characterizes problem (the chess piece state value and the address code of each point are directly delivered on the P2 mouth).

During microcomputer note spectrum, when interrupt signal was arranged, the crosspoint address code that chess piece falls under journal on the bus then could.This has just obtained chess piece " sequence number of beginning " information.

The effect of three state buffer is that bus is isolated and data buffering.Just can make 361 information acquisition unit circuit on 361 crosspoints hang (parallel connection) simultaneously on microcomputer data I/O port with it.C1, C2 and R0 constitute differential circuit (when magnetic induction switch moves) and send a spike signal to the input of one-shot multivibrator 74LS121, and 121 output then sends a square-wave pulse.The timing parameter that the time interval conduct of square-wave pulse is played chess, the three state buffer of this address code of control and management is simultaneously opened, and to the data/address bus carry information, and sends interrupt signal notice microcomputer and carries out data acquisition and processing.

Owing to adopted differential circuit, have only when chess piece falls Shi Caihui to produce a point towards signal, make the three state buffer of an address of a square-wave pulse control of 121 outputs open and send the break in service signal.Therefore guaranteed whenever to have only at most the information in a crosspoint to deliver to data/address bus.And chess piece is underground one by one, the phenomenon so bus can not get muddled.

The effect of R1 and R2 is that (behind the grape) discharges over the ground to C1, C2, so that produce the enough points of another amplitude towards signal when preparing to begin next time.

Decoding control circuit Y shown in Figure 3 finishes the control function that 9 inputs-361 line selections 1 are exported.When chess match end point order counting, by its control G1, G2 sends the colouring information of chess piece on each crosspoint to data/address bus.

As everyone knows, computer technology has been the application technology of a maturation now.After having finished the information gathering task, it then is very easy that information Processing is handled.

Figure 4 shows that working procedure block diagram of the present invention.Initial parameter is set following content, select laws of the game (China's rule? day this rule? the Ying Shi rule?) selection match time spent standard etc.Generally picking up counting earlier by black piece side, does judgement time use up? be then reading the clock, not play chess piece then to declare negative if the time reading the clock uses up; If there is chess piece to fall, then write down the color of chess piece, drop point site, the sequence number of beginning deducts the used time from the stipulated time, return the opposing party's timing; Does inquiry keyboard have or not services key to press or remote service request if no chess piece falls then? if have, whether the end key is pressed, and is then to put order to calculate victory or defeat and show; Print chess manual? be then to print, otherwise send chess manual, return by modem.
