Description

The invention relates to electronic equipment and can be applied at sports events as an integrating time counter, for example, for a chess game.

The purpose of the invention is to automatically determine the result of a chess match in time trouble.

The drawing shows a diagram of an electronic chess clock.

The clock circuit contains the second trigger 1 for controlling the sensor operation of the calibrated time stamps, the first button 2 called Black for timing the player with white pieces, the second button 3 titled White for timing the player with black pieces, the third button 4 Stop for stopping the time counters of both players, fourth button 5 "Setting the zero to bring the entire circuit to the initial state, sensor 6 calibrated time stamps, first trigger 7 to control the coincidence circuits and the operation of the stroke counter, first y scheme AND 8 matches, counter 9 counting sequence numbers of moves, second circuit AND 10 matches, first frequency divider 11, third decoder 12, second frequency divider 13, first counter 14 counting elapsed time for thinking about moves, control time presetting block 15 , block 16 of indication of the sequence number of moves, block 17 of presetting of moves, second counter 18 of counting the time spent on thinking of moves, first decoder 19, second decoder 20, first block 21 of indication of spent time for obd washing the moves, the first circuit 22 comparing the control and elapsed time, circuit 23 comparing the moves, the second circuit 24 comparing the control and elapsed time, the second block 25 indicating the elapsed time for thinking of the moves, the element OR 26, the first element NOT 27, the element AND-NOT 28, the second element is NOT 29.

Through buttons 2 and 3, the inputs of the trigger 7 are connected to the output of the element HE 29, and the outputs to the inputs of elements AND 8 and 10, the other inputs of which are connected to the output of sensor 6 of calibrated time stamps. From the zero output of trigger 7, a signal arrives at the indication board, with which the inscription “Black move” is lit, and from the single output - “White move. The outputs of each element And 8 and 10 through the dividers 11 and 13 are connected respectively to the counting inputs of the counters 14 and 18, and the counting input of the counter 9 is connected to a single output of the trigger 7. The outputs of the counters 9, 14 and 18 through the appropriate decoders 12, 19 and 20 associated with the corresponding output ends of the digital

indicators. The inputs of time comparison circuits 22 and 24 are connected to the outputs of block 15 of pre-set 1 control time and the corresponding decoders 19 and 20. The inputs of circuit 23 for comparison of strokes are connected to the outputs of block 17 for presetting strokes and descrambler 12. Signals from circuit outputs 22 and 24 comparing the time through the element OR 26 arrive at the first input of the element AND-NO 28, to another input of which a signal comes from the output of the circuit 23 comparing moves through the HE inverter 27. From the output of the element AND-NOT 28, the signal buys the input of the element NO 29 and at the entrance of the installation trigger 1, the unit installation input of which is connected to button 2. From the output of the element NOT 29, the signal enters the indicator board, with which the inscription "Time overdue. The output of the trigger 1 is connected to the input of the sensor 6 calibration time stamps.

Electronic chess clock works as follows.

After button 5 is pressed, counters 9, 14 and 18 are zeroed, triggers 1 and 7 are set to zero positions and sensor 6 of calibrated time stamps is locked. Using the time presetting unit 15, the control time given to the chess players is established, and using the presetting unit 17, the number of moves is exceeded by one number of control moves.

Before the start of the game, the referee gives the command to turn on the player’s time count with white pieces, which in this scheme is provided by pressing button 2, with the result that trigger 7 is set in such a position that gives the resolving potential on the AND 8 element and the inhibiting ON 10. The counter 9 registers what starts the first move. The board receives a signal, by which the inscription "White's move is highlighted, and trigger 1 is set in such a position that sensor 6 of the calibrated time stamps is started and through the AND 8 element of the time mark passes to the frequency divider 11 and then to the counter 14 whereby the time for thinking of moves for a player with white pieces is counted.

A player with BETTERS after his turn presses the button 3, into the cut. What is more, the trigger 7 is placed in such a position that the inscription "Black move. The counter 18 counts the time pa thinking of the moves of the player with the black pieces.

Then the player with the scooped figures presses button 2, and the i-rock with white figures button 3, and so on.

The device associates the number of moves with the elapsed time and makes it possible in time trouble to automatically determine the result of a chess match, which is carried out as follows. As soon as one of the opponents spends all the time given to thinking about moves, at the output of one of the comparison circuits 22 and 24, we get a logical unit, which through the OR 26 element enters the first input of the AND-NOT 28. If by that time the player, the game countdown the time of which is going at the moment, he does not have time to make control moves, then through the ele

ment NOT 27 to the second input of the element AND NOT 28 also receives a logical unit. As a result, on the light panel, along with the inscription White move or Black move, the inscription says Time has expired and trigger 1 is set in such a way that sensor 6 of calibrated time stamps does not emit pulses and the time count ceases. If the parties donithe make the control moves, then at the output of the comparison circuit 23, we obtain a logical unit, thereby preventing the display of the inscription "Time overdue."
