[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
A system for measuring a section passing time of a racehorse in an embodiment of the present invention will be described.
[0013]
FIG. 1 is a block diagram of a system for measuring a section passing time of a racehorse according to an embodiment of the present invention.
(About the basic configuration of the system for measuring the section passing time of this racehorse)
As shown in FIG. 1, the system for measuring the section passing time of a racehorse basically includes an ID oscillator 1, an ID receiving device 2, a passing sensor 3, transmitting and receiving antennas 4a and 4b, a lap time display panel. 5, a processing device 6, and a personal computer 7 as a main control device.
[0014]

The time from when the ID receiver 2 of the start gate receives the radio wave d from the ID transmitter to when the ID receiver 2 of the goal gate receives the same radio wave d in the section is measured by the clock device in the personal computer 7. The lap time display panel 5 displays the horse numbers, section passage times, and the like corresponding to the measured ID codes.
[0015]
In this embodiment, the pass sensor 3 is arranged at each gate in the section as a backup for when the ID receiving device 2 cannot receive the radio wave d from the ID transmitter 1. The time from when the passage sensor 3 at the start gate of the section detects the passage of the racehorse h to when the passage sensor 3 at the goal gate of the section detects the passage of the racehorse h is measured.
(About the configuration of the ID transmitter 1)
The ID transmitter 1 transmits a radio wave d (showing only a strong portion of the radio wave) including a unique ID code, and as shown in FIGS. Attach to the back of the head. The radio wave d from the ID transmitter 1 has a directivity in a direction perpendicular to the running direction of the racehorse h so that the radio wave d reaches the ID receiver 2 regardless of the running position of the track s. It is possible to transmit a distance of 10 m or more in each case (see FIGS. 3 and 4). The radio waves d from the ID transmitters 1 have the same frequency, but have different ID codes for each ID transmitter 1.
[0016]
Since the ID transmitter 1 has the jockey m mounted on the back of the head as described above, a plurality of racing horses are required as compared with a conventional example in which a transmitter for continuously transmitting ID pulses is mounted on a racing horse. Are almost simultaneous, the possibility that the radio wave d from the ID transmitter 1 is interrupted is extremely low, so that measurement is rarely impossible.
[0017]
In addition, since the ID transmitters 1 attached to the respective jockeys have the same frequency, only one ID receiving device 2 is required for each gate, and the entire device is inexpensive.
(About the configuration of the ID receiving device 2)
As shown in FIGS. 1, 3 and 5, the ID receiving device 2 is composed of a gate controller 20, an ID receiving antenna 21, and a cable connecting these components to each other. To receive (read the ID code) the radio wave d including the ID code. In addition, the receiving device 2 can sufficiently receive the moving speed of the ID oscillator 1, that is, the running speed of the racehorse h, which is 50 to 60 km / h. In order to enhance the directivity, the position, the angle, and the number (element) are determined, and the frequency and the amplification degree are determined by a preamplifier in the receiving device.
[0018]
Note that the gate controller 20, the ID receiving antenna 21, and the cable are mounted via a bracket or the like to a support 9 provided every 200 m (1 ha) on the side of the runway s.
[0019]
The gate controller 20, the ID receiving antenna 21, and the cable have a structure that can be easily attached to and detached from the column 9 so that the installation location can be relatively easily changed.
[0020]
Further, the power supply of the gate controller 20 is secured by a battery or a solar system, thereby eliminating the necessity of burying power supply / signal wiring under the road or overhead wiring.
(About pass sensor 3)
As shown in FIG. 1, the passage sensor 3 is a sensor using infrared rays and / or a sensor using a photoelectric tube, and reflected light such as infrared rays radiated from the irradiation unit 30 to the reflection plate 31 competes. It is a type that emits an output signal when not returned by being interrupted by a horse. The passage sensor 3 is also attached to the support 9 in the same manner as the gate controller 20, ID receiving antenna 21, and cable.
[0021]
Here, the passage sensor 3 has a backup function that enables display and recording of a lap time without a horse number when a reception (reading) error of the ID receiving device 2 occurs.
[0022]
The passage sensor 3 is used as a sensor for manually adjusting the angle of the receiving antenna of the ID receiver and the directivity of the radio wave including the ID code from the ID transmitter 1. Data such as the position is stored as dedicated software in the memory of the CPU in the processing device 6. The dedicated software manually adjusts the position and angle of the receiving antenna 20 of the ID receiving apparatus 2 so that the passing lap time by the passing sensor 3 and the lap time obtained by reading the ID code of the ID receiving apparatus 2 can be manually set to the same value. The standard is converted into a numerical value, and the numerical value is displayed on a monitor of a personal computer 7 at a higher rank of the processing device 6.
[0023]
On the other hand, the passage sensor 3 is used as a correction sensor for correcting the read / take time of the read timing of the radio wave d from the ID transmitter 1 by the ID receiving device 2. The function of correcting the time of the early pick-up and the late pick-up is stored in the memory of the CPU in the processing device 6. The software uses the time when the passage sensor 3 is ON as a reference, and calculates the time obtained by adding the difference between the reading time by the ID receiving device 2 and the reference time in the case of the quick retrieval, and the reading time by the ID receiving device 2 in the post-fetching. It has a function of setting the time obtained by subtracting the difference from the reference time as the passage time of the section. With this function, it is possible to improve the accuracy of the variation in ID reading time caused by wireless communication.
[0024]
Therefore, the backup function of the passage sensor 3 has excellent time accuracy.
(Regarding the configuration of the transmitting / receiving antennas 4a and 4b)
As shown in FIG. 1, the transmitting / receiving antennas 4a and 4b wirelessly connect the ID receiving device 2 and the passage sensor 3 to the lap time display panel 5, the processing device 6, and the personal computer 7 of the main control device. The presence of the antennas 4a and 4b eliminates the necessity of burying the signal wiring under the road or an overhead wiring.
(Lap time display panel 5)
The lap time display panel 5 is as shown in FIG. 6, and displays a horse number and a jockey name obtained from a radio wave d including a unique ID code, and a time when the racehorse of this horse number passes through the section. It is.
(Personal computer 7)
The personal computer 7 has a function of registering a horse name and a rider name corresponding to a unique ID code.
[0025]
It has a function of selecting an interval / random start or a clockwise / counterclockwise selection.
[0026]
Either the horse name or the rider in the passing time record (lap time), a specific date and its period can be searched.
[0027]
The section passing time has a function of displaying each lap time and the total time in real time in the passing order.
