The invention relates to devices for controlling the comparative time evaluation of the actions of athletes in competitions and training sessions with a separate start, for example, in cross-country skiing.

The purpose of the invention is to improve the usability of the device.

The drawing shows a functional diagram of the device controlling the time of the race for athletes with a separate start.

The device contains a keyboard 1, the outputs of the sign numeric buttons of which are connected to the inputs of the logic element OR 2 and the encoder 3, the outputs of which are connected to the information inputs of the first register 4. The counting input of the first counter of 5 pulses is connected to the output of the generator of 6 pulses, and the zero input is to the first element 7 controls The output of the element OR 2 is connected to the first control input of the first Dick register to the setup input to the single state of the trigger 8, the zero input of which is connected to the output of the second counter of 9 pulses, and the output is connected to the second input of the And 10 element, the first input of which is connected to the generator 6 pulses, and the output with the input of the second counter 9, the second control input of the first register 4 and the control input of the second register 11, whose information input is connected to the output of the first register 4, and the outputs to the input of the first decoder 12, output which is connected to the indicator 13. The outputs of the second register 11 are connected to the information input of the third register 14 and the first input of the multiplier 15, the second input of which is connected to the outputs of the fourth register 16, the output of the second control element 17 is connected to the control input of the fifth register 18, information the inputs of which are connected to the output of the first counter 5 pulses, and the outputs to the first input of the adder 19 a second, whose input is connected to the outputs of the multiplier 15, the outputs of the first adder 19 are connected to the first inputs of the second and a comparator 21, as well as information input of the sixth register 22, the control input of which is connected to the first output of the comparator 21 and the control input of the third register 14, and the outputs to the second inputs of the second adder 20 and comparator 21, the second output of which is connected to the control input of the removable register 23, the information inputs of which are connected to the output of the second adder 20. The inputs of the second, third and fourth decoders 24-26 are respectively connected to the outputs of the third, sixth, and seventh registers 14, 22 and 23, and out dy - to the inputs of the second, third and fourth indicators 27-29.

The device for controlling the time of the passage by athletes with a separate start works as follows. Keyboard 1 has ten keys with O to 9 characters. From the keyboard it enters 0 with the number of the competitor, which is converted into binary code by decoder 3 and accompanied by a sync signal with the element OR 2. At the start of the time reference, the trainer presses

5 key of the first control element 7 Starting the stopwatch. The low level signal is fed to the zero input of the counter of 5 pulses, after which the time pulses from the generator 6 start,

0 from zero.

30 seconds after the start of the time, the competitor with the breast number 1 starts, 30 seconds after it the participant with the breast number 2 starts and

5, etc. The trainer moves to the chosen control point of the distance. When a competitor approaches a control point, the coach enters the code of the participant’s number in the second register 11, which proceeds as follows. When you press one of the keys of the keyboard 1, the binary code of the digit is generated at the output of the encoder 3. Memorizing binary code numbers in first register 4

5 is made when the first control input of this register is received from the output of the element OR 2, which is generated when any key is pressed. At the same time, this signal is fed to the input

0 trigger 8 and translates it into a single state.

The signal of the logical unit from the output of the trigger 8 is fed to the input of the element And 10 and allows the passage of the counting pulses from the generator 6 to the input of the second counter 9, the second control input of the first register 4 and the control input of the second register 11, which overwrites the digit code from the four-bit Shift Register 4 in the second register 11 number of the participant. After the arrival of four pulses at the output of the second counter 9, a signal is generated that arrives at the round-up input of the trigger 8. The signal of a logical zero from the output of 5 and the trigger 8 prohibits the arrival of pulses from the output of the generator 6 to the output of the element 10. Thus formed. a pack of four pulses shifting the binary code of the digit from the first register 4 to the second register 11. On the next keystroke, the process is repeated and the binary register corresponding to the number of the competitor is placed in the second register 11. This code, through the first decoder 12, enters the input of the indicator 13, according to which the trainer controls the entry of the participant’s number into the second register 11. At the time the participant crosses the conditional line of the distance control point, the trainer presses the Fix button, which causes the formation of the first control signal 17 recording time in the fifth register 18 with the first counter 5 pulses. Thus, information is prepared for calculating the leader's time and the time the participant lags behind the leader. The calculation is made using the following formulas

 H Zs; (1)

Tp Tl-T4, (2)

where TA is the athlete's net time, i.e. the time elapsed since the start of the participant;

That is the time elapsed since the beginning of the reference time for the distance;

TP - the time of the loss of this participant to the leader;

H - the number of this competitor;

Zs - the starting delay, for example, is 30 seconds.

The start delay time is stored on Thursday register 16 and in binary code is fed to the second input of multiplier 15, the first input of which is supplied with the code of the participant’s number crossing the checkpoint. From the output of multiplier 15, an additional code equal to the product H 3C is fed to the second input of the first adder 19, to the first input of which a code equal to the time T0 is applied. At the output of the first adder 19, a TA code is obtained. The second adder 20 calculates the difference by the formula (2). Comparator 21 compares the value of T and T4. In case Tn is less than or equal to T /), the comparator 21 generates a signal permitting Tp code to be recorded in the seventh register 23, the value of which is indicated on the indicator 29. In the case Tl is longer than Tz, the first output signal of the comparator 21 is generated code T4 records from the output of the first adder 19 to the sixth register 22 and the H code - the participant numbers from the output of the second register 11 to the third register 14. Codes from the outputs of the third and fourth registers 14 and 22 are received via the decoders 24 and 25, respectively, to indicators 27 and 28 providing psd adding the number of leader H and the net time of the leader of the competition T. Indicator 29 displays the leader’s losing time.
