Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a timekeeping system for a moving object for measuring travel time between timing points, such as travel time for each set distance traveled by a moving object. For example, the present invention relates to a system for timing the total travel time for each predetermined section or for timing the training time of a racehorse, the race time, the race time of a car, etc.

(Summary of the Invention) The present invention is a timekeeping system for a moving object that uses a transmitter and a receiver to accurately and easily measure the travel time of various moving objects.

(Prior art and its problems) When measuring the travel time between timing points for each predetermined section of a moving object, using the example of measuring the training time of a racehorse, conventionally, a timer uses a stopwatch. As shown in FIG. 5, based on the index F set up at each predetermined section (furlong point), the time when the vehicle passed through that timing point was read.

However, in the case of such conventional means, passing the time measurement point is left to the visual judgment of the timer, and it requires skill and mental concentration to be able to measure time accurately. The drawback was that it required a lot of effort. In addition, even if an expert is an expert, even if the training time of the same racehorse is measured, the measured training time tends to be different depending on the timer, and furthermore, even if each timer is accurate, Even if the time was measured, there was a drawback that the relative position of the racehorse to the index changed depending on the position from which the racehorse was viewed, resulting in a time lag.

In particular, when timing the training time mentioned above, in addition to the racehorses that should be timed, there are many horses that are not subject to timekeeping, and they are shadowed by other horses, making it difficult to timekeeping and causing inaccurate timing. There are disadvantages that can easily occur. Additionally, there are cases where a single timer has to time the training times of multiple racehorses, such as three, almost simultaneously, and in such cases, the timer must keep an eye on multiple horses. , the disadvantage is that the timekeeping becomes even more inaccurate.

Furthermore, it has been difficult or impossible to measure time when it is raining, snowing, or foggy.

(Object of the Invention) The present invention has been made in view of the above circumstances, and provides an object to easily and accurately time the travel time of racehorses regardless of the number of racehorses to be timed or changes in their travel conditions. The purpose is to do so.

(Structure and Effects of the Invention) In order to achieve such an object, the present invention provides a communication area in a specific range that is attached to either one of a moving body moving between timekeeping points and the timekeeping points. a transmitting means for transmitting timekeeping data, a receiving means attached to one of the other for receiving the timekeeping data, and a receiving means for receiving the timekeeping data from the receiving means and transmitting the timekeeping data between the timekeeping points based on the timekeeping data. and a data processing means for measuring the travel time of the mobile object.

With this configuration, for example, a transmitting means is attached to the timekeeping point,
If a receiving means is attached to a moving body, as the moving body moves and enters a communication area, signals are sequentially received from the transmitting means. The receiving means stores data such as time measurement data in response to the signal. Then, after the moving object has finished moving, the receiving means is finally recovered, etc.
The receiving means is connected to a data processing means, the data stored in the receiving means is taken in, and the travel time at the time measurement point can be extracted using a printing means such as a printer or a display means such as a CRT display.

Therefore, since the travel time of a moving object is measured by transmitting and receiving data in a specific communication area, there is no need for visual judgment by humans, and errors due to differences in the viewing direction of the moving object and errors caused by other moving objects The view is not obstructed by
Now I can measure time accurately. In addition, since it does not rely on manual labor, not only does it not require skill, but no matter how many moving objects there are, the travel time can be easily and accurately measured, reducing the labor required for timekeeping and saving labor. In addition to being able to measure time more efficiently. In particular, when measuring training times for racehorses, it is possible to avoid variations in timing data caused by different timers, and to unify training times, which are important in determining whether a racehorse is doing well or not. This has the advantage of being able to inform fans as accurate data, which can lead to improved fan service.

FIG. 1 is a circuit block diagram showing transmitting means and receiving means according to an embodiment of the present invention, and FIG. 2 is a schematic configuration diagram of data processing means. Reference numeral 1 denotes a transmitting means that is attached to each of the timekeeping points separated by a set distance from the starting point of the training course where the racehorse as a moving object moves, and transmits timekeeping data in order to form a communication area A of a specific range. , 2 is a receiving means attached to the racehorse.

The transmitting means 1 includes a power supply section 3, a furon-specific code setting section 4, a data generating section 5 that generates and outputs a timing data signal corresponding to the code set by the furon-specific code setting section 4, and A modulating section 6 that modulates an output data signal into a unique frequency signal, and a transmitting section 7 (transmitting antenna) that transmits the modulated frequency signal are provided.

The furlong-specific code setting section 4 is configured to set codes corresponding to each fixed point separated by a set distance from the starting point in order, such as 1 furlong, 2 furlongs, etc., for each 200I111 so-called 1 furlong. It has become.

A solar cell 8 is connected to the power supply section 3 .

The transmitting means 1 is attached to the support column 22 of the index F installed for each furlong, and as shown in FIG. is starting to form.

The receiving means 2 is carried by a jockey R riding a racehorse H, as shown in FIG.

As a result, as racehorse H enters the training course, starts training, and gallops, communication area A for each furlong is created.

As shown in FIG.
Based on the time T, Tm= (T r+ T
t)/2, and the average time Tm is measured. That is, since the communication area A has an elliptical shape as shown in the figure, if you simply measure the time T when entering the communication area A or the time T when leaving the communication area A, the training course that the racehorse H passed will be calculated. Differences in position in the width direction cause a time difference, but by taking the average time Tm, time can be measured more accurately without creating a time difference, regardless of the position in the width direction of the training course.

Then, the time for each furlong is the above average time TI
Calculated by subtraction based on I+. In FIG. 3, 2 indicates a threshold value in the level discrimination means 13.

On the side, fixed data specific to each moving object may be set, and on the receiving means 2 side, the travel time of the corresponding moving object may be measured based on the fixed data. In this case, for example, it is possible to connect a large number of CRT display devices to the data processing means 17 and display the section time and total time moment by moment each time the section is passed. It has the advantage of being able to know the travel time in real time.

The present invention is applicable not only to measuring the training time of the racehorse H, but also to measuring the travel time of various moving objects, such as measuring the race time of the racehorse H, the test time of a car, and the race time.
