Abstract

The utility model discloses a live-timing chessboard. The utility model is characterized in that a magnetic switch, a diode and a capacitor is arranged under the chessboard on each position opposite to each stay point of the chessman. The normal closed switch of the magnetic switch is connected to the positive pole of the power supply when parallel connecting to the capacity, the normal open switch of the magnetic switch is connected to the positive pole of the diode, the negative pole of the diode is connected to the negative pole of the power supply via a relay, and the normal open contact of the relay is connected to the timing control switch. An iron plate is arranged under each chessman. During the competition, each time a chessman goes, the normal open switch of the magnetic switch is closed, and the capacity, the common relay and the power supply forms a circuit to charge the capacity. The circuit is connected and the normal open contact of the relay is closed to synchronized trigger the two timing control switch, i.e. timing A stops and timing B begins to work. The process is repeated to achieve automatic timing for each go.

Description

Chessborad having automatic timing device

One, technical field

The utility model belongs to chess apparatus technical field, but is specifically related to a kind of chessboard of self-clocking.

Two, background technology

Chessboard that existing board game is adopted and time set (clock) are two independent parts separately.When match, both sides predesignate time spent standard separately, measure the time that both sides take separately respectively with two clocks.When a side has walked a step chess crown, stop timing by clock at once, opponent's clock then starts, otherwise also like this.The operation of timing clock, stop to use manually-operated.Have plenty of the chess player and walked a step chess crown, oneself press the clock timing, have plenty of the third party of asking specially by the clock timing.This manual time-keeping mode can be brought following two weak points: chess player's energy high concentration during match, also to consider to take sb's mind off sth by clock timing meeting, and may influence the performance of chess player's level; If please the third party press the clock timing specially, still there is the error of service speed, if timing person lacks just attitude, will make match unfair situation occur.

Three, summary of the invention

The purpose of this utility model provide a kind of simple in structure, easy to operate, timing is accurate rapidly, benefits the concentrate one's energy Chessborad having automatic timing device of performance level of chess player.

For achieving the above object, the technical solution adopted in the utility model is: comprise chessboard and chess piece, be characterized in: adopted by the shared relay of magnetic switch, diode, capacitor, control timer and the control circuit that power supply is formed; Below chessboard, on the position of corresponding each chess piece foothold, magnetic switch, diode and capacitor are installed all; Be connected with positive source after the normally closed switch of magnetic switch and the capacitor parallel connection.The normal open switch of magnetic switch connects diode cathode, and diode cathode is connected with power cathode through relay, and the normally opened contact of relay is connected with the timer gauge tap.The following iron plate that all is equipped with of each chess piece.

Adopt said structure, connect two timers during match simultaneously, the Party A at first presses the gauge tap of timer, and timer is picked up counting.After the Party A fell chess piece, owing to below the chess piece iron plate is installed, the normal open switch that makes magnetic switch was by adhesive.Capacitor, shared relay and power supply form the loop at this moment, and capacitor is by power source charges, and the conducting loop, make shared relay work, the normally opened contact closure on it triggers the gauge tap of two timers and works simultaneously, Party A's timer timing stops, and Party B's timer timing begins.After the capacitor charging finished, the loop was blocked, shared relay normally open contact playback.Repeat said process, promptly realized the self-clocking function that whenever makes a move.After removing chess piece, the magnetic switch normally closed switch resets, and capacitor discharges rapidly, for charging is next time prepared.The utility model is simple in structure, reasonable in design, the power consumption is low, is applicable to that go, Chinese chess, chess and other need the chess of timing.

Fig. 2 is circuit theory diagrams of the present utility model.

Five, the specific embodiment

The chess piece 2 that iron plate all is installed below by Fig. 1, Fig. 2 as seen, the utility model is reached by chessboard 1 constitutes; Below chessboard 1 on the position of corresponding each chess piece 2 foothold 12, be equipped with magnetic force close open, diode 9, capacitor 8.Magnetic switch comprises normally closed switch and normal open switch, and this two switch is made of top normally opened contact 4, middle movable contact flat 5 and following normally-closed contact 3.In the upper end of movable contact flat 5 permanent magnet 6 is installed.The normally closed switch of magnetic switch and capacitor 8 backs in parallel and 7 anodal connections of power supply, the positive pole of capacitor 8 is anodal corresponding with power supply 7.The normal open switch of magnetic switch connects diode 9 positive poles, and 10 1 contacts of diode 9 negative poles and shared relay are connected, and its another contact connects power supply 7 negative poles, and its normally opened contact is connected with two timer 11 gauge taps respectively.The effect of diode 9 is to play buffer action.
