BACKGROUND OF THE INVENTION 1. Field of the Invention
And a device for displaying.

[0002]

2. Description of the Related Art Conventionally, in a swimming race, as shown in FIG. 3, a signal from a swimmer jumping from a diving board signal generator 3 provided on a diving board and a touch signal generator 4 provided on a Dutch panel as shown in FIG. The time difference from the touch signal is obtained by the output of the time counting device 5 and calculated by the difference calculation circuit 11, and the result is displayed on the display 6 or printed out by the printer 7.

In a relay competition, as shown in FIG. 4, a touch signal of a previous swimmer from a touch signal generator 4 and a dive signal of a rear swimmer from a diving board signal generator 3 are input to a relay takeover determination circuit 10. As a result, the information is output as relay takeover information to a counting circuit 9 for counting the number of relays, and the number of relays is stored. In addition, every time the swimmer touches the touch panel, the signal of the touch signal generator 4 is invalidated for a certain time thereafter.

[0004] Also, as shown in FIG. 5, a swimmer's dive signal and a touch signal for each lane are input to course boxes 11 arranged in each lane, and each course box 11 is connected to one cable. They were connected and output data for each course to the control circuit 1.

[0005]

However, if the touch signal of the touch panel is always enabled, the noise may be picked up by the force of the waves, or the touch signal may be disabled for a certain time after the touch in a relay event. Even if such a configuration is adopted, the above-described noise problem, or the body of the next swimmer accidentally touches the touch plate and picks up an incorrect touch signal, may not be able to record accurately.

In a normal domestic tournament, a single timing device is used, but in an international tournament or the like, a backup of the timing in case of a failure or malfunction is required. It is common knowledge of officials responsible for official timing to record accurate time,
Although mistakes and mistakes are not tolerated, there are times when conventional methods cannot cope.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a timing device capable of reliably recording and displaying an accurate time in a swimming competition.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, in a swimming race timing apparatus having a start signal generator, a diving board signal generator, a touch signal generator, and a timing circuit, a signal output from the diving board signal generator is provided. A diving board signal, and a signal distributor for each course to which a signal output from the touch signal generator is input via an input connector,
A control circuit for controlling the output of the signal distributor and the output signals of the touch signal generator and the timing circuit.The control circuit receives a signal from the diving board signal generator corresponding to a state in which an athlete is on the diving board. A mask circuit that enables the touch signal of the touch panel only at certain times, and a counter circuit that stores the number of relay athletes and counts the number of signal inputs from the diving board signal generator in this control circuit. The touch signal is enabled by the signal indicating the last swimmer of the counting circuit, and a display device that displays the result determined by the control circuit and a printer that prints the result are provided. It is possible to record and display reliably.

[0009]

In the timepiece for swimming configured as described above, the control circuit counts the difference between the output signal of the start signal generator and the dive signal of the diving board signal generator. Also,
The mask circuit in the control circuit obtains a signal from the diving board signal generator that there is a person on the diving board, enables the signal of the touch signal generator, and indicates that a person has left the diving board from the diving board signal generator The touch signal of the touch signal generator is invalidated by the signal. The counting circuit in the control circuit stores the number of swimmers in the relay event, disables the mask circuit when the final swimmer is reached, and enables the touch signal regardless of the presence or absence of a person on the diving board. The signal from the diving board signal generator and the signal from the touch signal generator are input to multiple control circuits via the signal distributor, so that even if one control circuit fails, another control circuit compensates can do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of the present invention. Output signals from the start signal generator 2, the dive board signal generator 3, the touch signal generator 4, and the timing circuit 5 are input to the control circuit 1. The diving signal S3 of the diving board signal generator 3 and the touch signal S4 of the touch signal generator 4 are input via the signal distributor 13. The control circuit 1 includes a masking circuit 8 and a counting circuit 9, and controls the signals of the signal generators to display necessary information on a display 6 and a printer 7
To print out.

FIG. 2 is an explanatory diagram of an operation for measuring the time of a swimming relay competition according to an embodiment of the present invention, and is an example in a case where four players relay a 200-meter competition. Let A be a start signal by the start signal S2 from the start signal generator 2.

The dive timing by the dive signal S3 when the swimmer dives from the dive table is B. A
If the time difference between the signals B and B is output and displayed from the difference calculation circuit 15 of the control circuit 1, it becomes T1, as shown in FIG.

The timing at which the next swimmer climbs the diving board based on the diving signal S3 from the diving board signal generator 3 is defined as C. When S3 is output to the mask circuit 8 of the control circuit 1, the touch signal S4 of the touch signal generator 4 becomes valid. First swimmer touches touch panel and signal S4
Let D be the timing at which this occurs.

The timing at which the next swimmer jumps immediately after the timing D and the signal S3 is generated is defined as E. If the time difference between the timings D and E is calculated and output in the same manner as the time difference between the timings A and B, the handover time, that is, the touch quality can be measured. The transition time between the second swimmer and the third swimmer is T3, the transition time between the third swimmer and the last swimmer is T4, and the difference between the respective transition times can be recorded, and whether or not flying is possible can be known.

When the signal S3 jumped by the second swimmer is input to the mask circuit 8, the touch signal S4 becomes invalid until the third swimmer climbs the diving board. The timing at which the third swimmer jumps and repeats the timings C, D, and E, the last swimmer climbs the diving platform, and the signal S3 is generated is F. The signal S3 of the timing signal F is input to the counting circuit 9, which recognizes the last swimmer from the signals S3 of the timings B and E and sends a signal to the mask circuit 8 to enable the signal S4 of the touch signal generator 4 to be effective. I do.

In this manner, by appropriately masking the signal S4 of the touch signal generator 4 by the mask circuit 8, the touch signal S4 between the timings B and C and between the timings E and F is provided.
4 becomes invalid. In this way, even if the previous swimmer or the next swimmer accidentally touches the touch board after the next swimmer jumps in the relay competition, the data is not picked up as touch data.

The present apparatus also has a function of always displaying and printing without passing through the touch signal S4 and the mask circuit 8. By using this function, it is possible to measure the time from when the swimmer touches the touch panel with his hand to when he or she turns and kicks it with his foot.

Further, the respective timings from B to I are input to the signal distributor 13 installed for each course and sent to the control circuit 1. The signal distributor 13 is provided with another course box 21, and another control circuit 3 is provided from the course box 21.
If the same signal from B to I is sent to 1, even if the main course box 11 goes down, there is data from the sub course box 21 so that accurate time can be reliably recorded and displayed.

[0019]

As described above, according to the present invention, by calculating and displaying the time difference of the dive from the start signal, the skill of the swimmer's dive can be measured, and the reflection time of the dive can be shortened even in an actual competition. Useful for practice. In addition, by calculating and displaying the time difference between the next swimmer's dive from the touch of the previous swimmer in the relay competition, it is possible to determine the presence or absence of flying, and it is also useful for practicing the success of taking over.

Further, it is also useful for practicing the goodness of the turn.
In addition, a mask circuit is provided in the control circuit, and the touch signal is appropriately masked by the mask circuit, so that an inadvertent touch is not picked up, and time keeping without erroneous determination in relay takeover is performed.

Also, when one of the timing devices has a fault,
By keeping the same data from the signal distributor to another timing device, it is possible to reliably record data. As described above, according to the present invention, the operation of the swimmer is converted into each electric signal and stored and operated by the plurality of control circuits, whereby accurate timekeeping can be reliably obtained.
