Abstract

The utility model relates to a chessboard used for kinds of chesses which need time termination and step meter. The surface of the chessboard is a metal surface. Each of the chesses even is a metal conductor. The metal surface of the chessboard is connected with an electronic clock integrated circuit and the video screen via a touch switch. The utility model links a timing display with the chessboard to a whole, and can carry out time keeping and displaying automatically for the both sides. The operation is very convenient.

Description

Timing chessboard

The utility model relates to a kind of chessboard, particularly need count the chessboard of step chess in limited time, as the chessboard of chess such as go, chess, Chinese chess and military chess.

At present, people play Weiqi, when Chinese chess or chess, especially during formal competition, all to relate to the problem in timing limit step, as go be to press by electronic clock separately by the both sides that play chess to finish in limited time, its control is carried out with beginning time synchronously, the chess player is every one to be gone on foot chess and must click electronic clock down, both disperseed energy, operation is more loaded down with trivial details again.In addition, along with the internationalization of Chinese chess and the universalness of chess, their timing limit step contradiction also can seem more and more outstanding.

The purpose of this utility model is exactly in order to address the above problem, and a kind of Timing chessboard of self-clocking is provided.

Technical solution of the present utility model:

A kind of Timing chessboard, it includes chessboard 1 and chess piece 2, and the surface that it is characterized in that chessboard 1 is a metal covering, and each chess piece 2 is metallic conductor, and the metal surface of chessboard 1 is connected with integrated circuit of electronic clock and display screen thereof by the touch switch.

The utility model organically is connected as a single entity timing display and chessboard, when the chess player plays chess, as long as have a side chess player to begin or during mobile chess piece, the utility model just carries out timing and demonstration, its accuracy height, good reliability to the opposing party chess player's time spent automatically, need not the chess player and remove to disperse energy, easy to operate, the automaticity height is particularly suitable for as various board game chessboards.

Fig. 1 is a connection diagram of the present utility model;

Fig. 2 is the connection diagram that the utility model is implicated long-pending timing;

Fig. 3 is a Board of chess schematic surface of the present utility model.

As Fig. 1,2,3, the utility model chessboard 1 also can be nonmetallic materials and makes, as bakelite plate, plastic plate etc., as long as the chess ruling of its chessboard 1 is a plain conductor.When playing chess, when the either party moved, as long as move or fall metallic conductor chess piece 2, chessboard 1 just had triggering signal output, by the work of soft-touch control control integrated circuit of electronic clock.Soft-touch control can be by single fortune amplifier IC ₁(model is μ A741CP) and bidirectional analog switch I C ₂(model is CC4016B) formed, and also can be made up of other circuit, single fortune amplifier IC ₁Input 3 pin be connected IC with the metal covering or the metal chess lattice lead of chessboard 1 ₁Output 6 pin and bidirectional analog switch I C ₂Input control end 6,13 pin connect IC ₂Input/output terminal 8,9 pin and integrated circuit of electronic clock IC ₃Clear terminal 21,22 pin of (model is TMS3450ML) connect, like this, and after the Party A that plays chess begins, just by soft-touch control IC ₁, IC ₂With integrated circuit of electronic clock IC ₃Zero clearing, at this moment integrated circuit of electronic clock display screen IC ₄(model is LTC-1850A ₁P ₂) shown timing time just is the Party B's that plays chess think time, after the Party B begins, again with integrated circuit of electronic clock IC ₃Zero clearing, display screen IC ₄The think time that then shows the Party A, thus the process in meter step in limited time finished automatically.

The utility model also can respectively be established a hour counter jumper totalisator IC in the both sides of chessboard 1 ₁₀, IC ₁₁(can adopt Sharp's 838 calculators), as Fig. 2, their timing control end respectively with separately soft-touch control IC ₆, IC ₇And IC ₈, IC ₉Input/output terminal 8,9 pin connect IC ₆, IC ₈Still be single fortune amplifier (model is μ A741CP), IC ₇, IC ₉Still be two-way simulate switch (model is CC4016B), two soft-touch control IC ₆, IC ₇And IC ₈, IC ₉Input 3 pin meet analog switch IC ₅The output of (model is TL601), IC ₅Input control end 2,3 pin contacts touch switch I C ₁, IC ₂Middle bidirectional analog switch I C ₂Another group input/output terminal 1,2 pin, IC ₅Input 4 pin meet integrated circuit of electronic clock IC by normally closed button K ₃Data output end 14 pin.The display screen IC of integrated circuit of electronic clock ₄Can be positioned at the circle, river middle (as Fig. 3) of chessboard 1, this is more suitable for Chinese chess and military chess, for go and chess, and display screen IC ₄Can be positioned at a side of chessboard 1, two hour counter jumper totalisator IC ₁₀IC ₁₁Display screen lay respectively at the two ends of the chessboard 1 of both sides' correspondence.

After the utility model is connected power supply, integrated circuit of electronic clock IC ₃Analog switch IC is passed through in work between institute's timing ₅Be input to Party A's hour counter jumper totalisator IC ₁₀In, after the Party A touched metal chess piece 2, triggering signal was sent into single fortune amplifier IC through the metal covering or the chess lattice plain conductor of chessboard 1 ₁, trigger bidirectional analog switch I C ₂Conducting makes integrated circuit of electronic clock IC ₃Zero clearing, after Party A's hand leaves chessboard 1, integrated circuit of electronic clock IC ₃Reclocking, analog switch IC at this moment ₅Output overturn, with IC ₃The reclocking time deposit Party B's hour counter jumper totalisator IC in ₁₁In, carry out so repeatedly.Like this, integrated circuit of electronic clock display screen IC ₄The time that shows is that hour counter jumper totalisator IC is moved the time in play chess the other side's thinking ₁₀, IC ₁₁Indicate the two sides accumulated time of moving separately respectively.In the process of moving, need suspend as special circumstances, or cry in the go in the time of need taking chess piece away when eating, the time of this moment should not count, so can finish by normally closed button K, with K disconnection, makes integrated circuit of electronic clock IC ₃Timing time can't be input to hour counter jumper totalisator IC ₁₀, IC ₁In 1.
