Description

Chessborad having automatic timing device

Technical field

The utility model belongs to amusement, sports articles for use technical field.

Background technology

At present, when chess contest as go, chess, Chinese chess etc. all need timing, sportsman often makes a move and need press a stopwatch, to realize timing, its deficiency is inconvenient, often play chess one innings, sportsman needs to press tens times even up to a hundred times, sometimes also can cause timing uncertainty due to human error.

Summary of the invention

The purpose of this utility model is: provide a kind of Chessborad having automatic timing device, and it can carry out effective timing to chess when racing automatically.

The technical solution of the utility model is: P1.2 ~ P1.7 pin of single-chip microcomputer U1 connects rotary control switch, photoelectrical coupler OP1, OP2 connects P1.0 and the P1.1 pin of single-chip microcomputer U1, the P3.5 pin of single-chip microcomputer U1 is connected relay by coupling resistance with switching tube, run during Control timer, the P3.4 pin of single-chip microcomputer U1 is connected relay by coupling resistance with switching tube, stop during Control timer, the P3.1 pin of single-chip microcomputer U1 is connected loudspeaker by coupling resistance with switching tube and connects, P3.2 with the P3.3 pin of single-chip microcomputer U1 is connected LED respectively by coupling resistance with switching tube and connects.

The beneficial effects of the utility model are: structure is simple, increase chessboard cost not high, accurate timing, convenient, decrease erroneous judgement and the working strength of referee.

Fig. 2 is that the utility model chessboard node cuts open top view;

Fig. 3 is the utility model time control circuit figure.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figure 1, 2, to be play chess power button B, 11 be 1 be judge control zone, 2 are switches, 3 are USB interfaces, 4 are timing display A, 5 are displacement power button A, 6 are timing display B, 7 are displacement power button B, 8 to be play chess power button A, 9 be when penalizing button A, 10 when penalizing that button B, 12 is that chessboard begins that node, 13 is chess piece induction chips.

Chessboard is as Fig. 1: centre is play chess district, surrounding have various function button (lamp), one jiao of the chessboard back side have switch and usb data interface, chessboard inside to have circuit board.

Chess piece is a kind of induction chess piece, inductor on chessboard below chess bit region can sense that chess piece has been put on chessboard, thus connects circuit, starts timing and exchanges play chess power, when sensing that chess piece is put on chessboard next time, stop current timing and exchange the timing that play chess power starts this side simultaneously.

Circuit board:, central processing unit U1, model can select W79E2051, is responsible for the record of all function commands and data.

Timing display: record the remaining play chess time in seconds, have the function arranging the play chess time limit, if reach play chess when prescribing a time limit, then starts sound and flicker is reported to the police.

Displacement power button (lamp): be only limited to chess, indicates displacement power when lamp is bright, without displacement power when lamp goes out.Namely a play chess calculated by the chess piece that falls for twice.

Play chess power button (lamp): have play chess to weigh when lamp lights, weigh without play chess when lamp goes out.When pressing, lamp is bright starts timing simultaneously.

Button (lamp) when penalizing: when judging button when pressing the penalizing of this side, lamp lights, the loss of timing do not come into force for the last time.Judge's input, by the time (unit: second) of penalizing, will be reduced by the remaining time of penalizing on the timing display of a side, and after judge's ruling, just press the play chess power button that play chess weighs a side, the lamp on the play chess power button of this side lights and timing simultaneously.

Referee's crease: be similar to play chess position, function is that this region then stops the timing that play chess weighs a side when sensing chess piece, knock out the play chess power lamp of this side, open the opposing party's play chess power lamp, but do not start timing, until when having the chess piece of triumph to fall on chessboard or restart timing, if both sides' chess piece is lost simultaneously, then press by judge the play chess power button that play chess weighs a side, continue play chess.

Play chess position is as Fig. 2: be a region having inductor and photoelectrical coupler, the chess piece on chessboard can be sensed, sense that the play chess power lamp then stopping this timing after on chess position immediately, knock out we fallen by chess piece, start the timing of the opposing party simultaneously and light play chess power lamp, until sensed that another piece of chess piece is fallen on play chess position.

Usb data interface: transplant in computer for live fact and file.

Play chess district: intermediate blank region is play chess district.

Use: when playing chess, judge opens switch, press play chess power button (lamp) that play chess weighs a side, lamp lights timing simultaneously, when namely play chess one step has one piece of chess piece to fall on chessboard play chess position, after inductor below chessboard senses chess piece, circuit board controlling functions sends instruction and exchanges play chess power, namely stops this side's timing to start the other side's timing, knocks out this side's play chess power lamp simultaneously and starts the other side's play chess power lamp, the other side starts play chess, until play chess terminates or reaches the play chess time limit of regulation.If will punish offending side, button (lamp) when then pressing the penalizing of the side that is punished, system cancels last unenforced timing, both sides stop play chess, reason of sentencing to be cut terminates, when namely penalizing one party after (remaining time in this side's timing display is by corresponding minimizing), judge presses the play chess power button that play chess weighs a side, continues play chess.If national Chinese chess, when needing to be shifted, then press displacement power button (lamp), each party is right for once, has the right when namely lamp is bright, exercises a back light and has just knocked out.If when can eat up the chess to square chess, two pieces of chess pieces of antagonism are put into referee's crease, when referee's crease has sensed chess piece, then stop timing, when the chess piece of triumph side is put back on chessboard by judge (if both sides' chess piece is lost simultaneously, judge presses the play chess power button that play chess weighs a side), then exchange play chess power, starting has play chess to weigh the timing of a side, continues play chess.If need to carry out live to fact, then with usb data interface, data are spread out of on live display (or computer), be just equivalent to play chess in computer the same (both sides' timing can be shown), carry out live.If need to study later, then utilize usb data interface to be transplanted to by file in computer and reproduce live and can various statistics and analysis be carried out.

The scope of application: Chinese chess, chess, Chinese army chess, go.
