Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, in training a racehorse or the like, measures and displays the elapsed time for each fallon to check the finished state of the training of the horse, and sometimes to predict the measurement result. It relates to a system used to collect measurement data for publication in newspapers.

[0002]

2. Description of the Related Art Conventionally, in training a racehorse or the like, the elapsed time for each fallon was carried out manually by 3 to 4 persons using a stopwatch. After that, a passage detector for detecting passage of the racehorse is installed at a predetermined position of the racehorse track, the passage time is measured from the detection result of the passage detector, and the racehorse lap time measuring device for displaying the measurement result is the same. Developed by the applicant. (See Japanese Patent Application No. 6-104181.)

However, since the measuring device measures the time taken for a horse to pass on the measuring line by means of a light emitter and a light receiver and cannot identify individual racehorses, the measurement is performed by running one horse at a time. Or, when multiple horses started at the same time, I could only measure when the first horse passed the measurement line.

[0004]

SUMMARY OF THE INVENTION The present invention is an improvement of the conventional racehorse lap time measuring device, and by adding the ability to identify each horse, individual horses can be started even when a plurality of horses start at the same time. It is an object of the present invention to provide an individual identification measuring system capable of measuring the elapsed time after passing the measurement line for each horse.

[0005]

According to the present invention, an individual identification measuring system for measuring and displaying a moving time of a predetermined section of an individual moving body is provided for each predetermined distance of a predetermined section of a truck for measuring a lap time. , Distance discrimination wave radiating means for radiating discrimination waves such as light on a measurement line at a predetermined distance, repeater equipped with a receiver for receiving measurement signal transmission wave from each moving body, time mounted on each moving body A timepiece transmitter provided with a measuring transmitter is mounted on each moving body, and the time measuring transmitter detects the radiated wave of the distance identifying wave radiating means, measures the elapsed time from the start line, and relays together with the identifying signal of each moving body. The central device connected to the repeater individually aggregates the measurement time of each moving body for each predetermined distance of the predetermined section, and displays the result.

It is an application of the present invention that the moving body is a horse, the predetermined distance is a fallon, and the radiating means is a projector.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an outline of a system used in the present invention. In FIG. 1, reference numeral 1 denotes a central device, which counts the measured time of each moving body for each horse and displays the result.

Numeral 2 is a distance discrimination wave radiating means which is provided for each predetermined distance of a predetermined section of the track for measuring the lap time and radiates a discrimination wave such as light on a measurement line having a predetermined distance. In this embodiment. It is a floodlight. In the case of a racehorse training track as in this embodiment, the floodlights are installed at the start point, the 4 fallon point, the 3 fallon point, and the finish point, for example, as shown in the figure. (Note that 1 Fallon is 200 m.)

Reference numeral 3 denotes a time measuring transmitter (hereinafter, simply referred to as a transmitter) attached to a horse or a human body (jockey), and 4 denotes an identification signal for each individual horse based on the data measured by the transmitter. It is a repeater that receives with. Above transmitter 3
Is transmitted in front of the radiated light on the distance identifying measurement line emitted by the projector 2, and the transmitter measures the elapsed time from the start line by the distance identifying signal received at the time of the passage, and the measurement is performed. The data is wirelessly transmitted to the repeater together with the individual identification signal.

In this embodiment, the start is detected by using a projector for projecting light on the start line. However, when a start gate is used, the opening / closing signal of the gate may be used as it is. In the case of a boat race that is approaching before the start and finishes at the start time, the former start detection method is inevitable. In this case, the start detection also serves as the determination of flying.

FIG. 2 is a view showing the appearance of the time measuring transmitter. In FIG. 2, 5 is a condenser lens, 6 is a gain adjusting volume, 7 is an ON / OFF switch, and 8 is a charging terminal.

The operation of the individual identification measuring system of FIG. 1 is performed as follows. The relays and the transmitter are wirelessly connected, and the transmitter transmits radio waves at 400 MHz and 10 mW. The frequency is 42 in this example.
0.0425 MH at 9.425 to 429.650 MHz
10 channels are prepared at z intervals, and channels with less interference are used. The radio reachable range is
It is about 100 m. Each transmitter starts transmission for the first time after receiving the ready request from the start relay, and puts the sensor in the reception enabled state.

Each transmitter is equipped with a sensor for receiving radiation (sensor beam) for distance identification, and the measured value is stored each time the sensor receives the sensor beam. The measured value is sent back to the repeater side at the transmission timing from the repeater side. FIG. 3 shows how to adjust the transmission timing. Further, FIG. 4 shows an overall view of a task flow between the central unit (PC), the repeater, and the transmitter.

When the START key is pressed, a ready request is sent from the central unit to the start repeater, and in response to this, the start repeater sends a ready request to each transmitter. In response to the ready request, the transmitter with the younger ID number starts transmission, and when the transmitter with the next ID number receives the transmission data of the transmitter with the previous ID number, the transmitter transmits the data. And repeat sending and receiving one after another.
FIG. 5 shows a signal format between the repeater and the transmitter. Each signal is a horse ID, a beam NO. It consists of 9 bytes such as TIME. The bit rate of transmission is 2400 BPS, and in the case of this embodiment, four consecutive transmissions are performed for one transmission, and the number of transmission bits is 72 bits /
2400BPS = 4 times 30msec + 10msec
(Margin), that is, 130 msec is the occupied time of each transmitter. Since these are sequentially transmitted by changing the number of transmitters, the maximum number of transmitters is 18, and if one margin is taken as 19 and one cycle is 130 msec × 19
= 2.47 seconds. Normally, the horse speed is about 16.6.
Since it is m / s, transmission / reception of 2.42 cycles is possible during 100 m running.

The operating principle of each oscillator is as follows. 1. After receiving the ready request from the start relay, each transmitter starts transmitting for the first time. 2. After receiving the clear request from the start repeater, the transmission ends. 3. The receiver stores the measured value each time the sensor beam is received. 4. The measured value is transmitted to the repeater at the transmission timing.

The operating principle of each repeater is as follows. 1. When there is a ready / clear request from the central unit, the request to each transmitter is transmitted at an interval of 2.47 seconds. 2. Since each repeater transmits from each transmitter in accordance with the transmission interval timing, its own sensor beam N
o. And measured value, the sensor beam No. immediately before. And the measured values are stored. 3. When the measurement value request is transmitted from the central device, the stored measurement value is transmitted. 5. When the stop request is transmitted from the central device side, the transmission is terminated.

FIG. 6 shows a method of storing the timer of each repeater. As shown in the figure, the measured values transmitted from the transmitter are stored in the order of arrival. FIG. 7 is an example of a display screen of the central device. 5 and 6, each horse is 1-
Numbered up to 18, with appropriate numbers. The number serves as an identification signal for the horse.

Therefore, in this embodiment, 18 transmitters are prepared. The screen includes a title area 9, a measurement value area 10, a file list area 11, a repeater communication status area 12, a message area 13, and a menu bar area 14.

In the title area 9, the title name and the date are always displayed, and the time is displayed only when the measurement is started or when the file is loaded. The displayed time is the time when the start key is pressed.

In the measurement value area 10, the fall times of 4F, 3F, and the goal after the start sensor is cut off are displayed for each horse. In the file list area 11, the measurement system and sensor information of each horse are displayed during measurement, and the file list in the disk is displayed during file loading. In the repeater communication status area 12, the communication status with each repeater is displayed, and in the case of an error, the error repeater name is displayed. Guidance messages and error messages are displayed in the message area 13 each time. Executable processes are displayed in the menu bar area 14.

FIG. 7 shows an initial screen. When START is pressed, the screen shifts to the measurement screen shown in FIG. S in the title area
The TART pressing time is displayed, and then the measurement system and sensor information of each horse are displayed in the file list area as shown in FIG. The transmitter corresponding to the request from the central unit changes from white to light blue, indicating that it is in use.
After that, the color of the sensor name changes to the same as the color of the sensor name by the reception of the distance identifying projector. (For example, when a horse crosses the finish line, the display color changes from light blue to red.)

At the same time, in the measurement value area, as shown in FIG. 10, the Fallon time from the time when the start sensor is cut off is displayed each time the sensor is cut off. If the transmitter is not activated at the time of measurement, or if Fallon time cannot be obtained even if it is activated, the split time there is a broken line (.........). When all transmitters that cut off the start sensor cut off the goal sensor, the measurement is automatically terminated. In addition, S in the menu bar
It is also possible to manually end the measurement by pressing the TOP key.

When the measurement is completed, the screen becomes as shown in FIG. 11, and the menu bar for the next processing is displayed. To store the fallon time, press the SAVE key, and to print, press the PRINT key. Press the ESC key to move to the next measurement, or press the EXIT key to end the system.

When reading the data that has already been stored, pressing LOAD on the initial screen displays the measurement value file on the disk in the file list area. Can be displayed on.

[0025]

As described above, according to the present invention, when the lap time is measured in training a racehorse or the like, the lap time can be automatically measured and displayed without manual intervention as in the conventional case. Therefore, the measurement result can be obtained easily and quickly, which is a great effect.

Further, the conventional racehorse lap time measuring device does not have the ability to identify each horse, and when only a plurality of horses are running, only the leading horse can be detected. By adding the identification ability of each horse, even when multiple horses start at the same time, it is possible to measure the elapsed time for each horse to pass the measurement line for each horse. Simply
In addition, the lap time can be automatically obtained.
