Description

  The present invention relates to a measuring device and a measuring method for a racehorse training clock.

  A racehorse of a horse race is managed and trained by a stable related person such as a trainer who operates the stable in the stable, a training assistant, a training general worker, and a general staff, and starts running on a racetrack. Training of racehorses is performed at each course in the training center adjacent to the stable, and it is said that it is overtaken before the race, and at the Japan Central Racecourse, it is like a donut like an actual racetrack course. For example, a distance of 800 m to 1600 m is formed on a slope such as a dirt course, a turf course, a wood chip course, a new poly track course (hereinafter collectively referred to as “Honbaba”) and a slope course provided on an uphill slope. Generally, it is performed in accordance with the driving lap and the strength of training as instructed by the trainer. Hereinafter, the training courses such as Honbaba and Sakaji courses are collectively referred to as “training courses”.

  The running time at the time of the above cut-off is announced as a follow-up clock (hereinafter referred to as “Training Clock” or “Training Time”), and the trainer determines the condition and finish of the racehorse based on this training clock. In addition to making judgments, fans who purchase betting tickets make race predictions with reference to training clocks that have been published, for example, on horse racing forecast papers. Thus, the training clock is extremely important information for holding a horse race.

  This training clock is based on the position of the halon stick indicating the goal provided adjacent to the inner peripheral edge of each course, and from this goal it is 200 m, 400 m, 600 m, 1 halon (200 m), 2 halon, 3 halon, etc. It is shown as the running time of ...

  At present, the time of the training clock is measured by a goal board installed at the inner periphery of the course while looking into the binoculars from the bleachers while a person who is making a prediction on the horse racing paper called Trackman in Honba. It is carried out by manual measurement in which the button operation of the stopwatch is performed at the timing when the racehorse passes through a halon rod erected at a position separated from the goal plate by 1 halon, 2 halon, 3 halon, ....

  On the other hand, on the slope course, a bar code is attached to the back of the racehorse, and this bar code is read by a bar code reader installed at a gate provided for each halon from the goal position to measure the passing time. (Patent Document 1).

  These training clocks are usually in units of seconds with a single decimal point, such as 12.5 seconds (200 m), 25.7 seconds (400 m), 38.0 seconds (600 m), and 53.2 seconds (800 m). It is measured to the tenth of a second.

  By the way, at present, training centers are set up in two regions, the Kanto region and the Kansai region, at the Japan Central Horse Racing Association, while 10 racetracks are scattered throughout the country from Hokkaido to Kyushu.

  Horse races are held on a predetermined schedule and are held every week at two or three of the ten locations. For example, during the summer season, it may be held simultaneously at the racetracks in Hokkaido and Kyushu. At this time, the racehorses are preliminarily used because of their transportation to racetracks far away from stables in Kanto and Kansai. It is often done to stay in the stables prepared for the race, and to run on the race after training on the course of the racetrack.

  The training clock in this case is also carried out by manual measurement using a stopwatch based on a goal plate and a halon rod installed at the inner peripheral position of the racetrack course.

JP 2000-157091 A (see paragraph 0002)

  However, the training clock of the halon unit conventionally used conventionally is not the time when the racehorse runs through 1 halon (200 m), 2 halon (400 m),. In other words, the time of one halon unit in the conventional training clock is due to the passing time at the position of the shortest distance when the inside of the course is run without waste, and the follow-up of training at the above-mentioned training course is the main course. In the case of cutting, the racehorse often travels in the middle of the track or on the outer corner of the curve, which means that the racehorse travels excessively when the actual distance is measured. Therefore, the time shown as a conventional training clock is actually a numerical value when the vehicle travels a distance longer than 200 m, 400 m, 600 m, or the like. Therefore, even if you run through the inside of the training course early, the speed may actually be slower than if you run through the outside of the training course at a later time. It is difficult to compare good and bad.

  On the other hand, manual measurement using a stopwatch as described above is based on the angle (observation angle) between the observation position and the halon rod, because a person operates the stopwatch while looking at the halon rod from the observation position. Cannot accurately determine when the racehorse has passed the position of the halon rod, and in addition to the speed of human movement, the racehorse that runs at a high speed of about 50-60 km / h is the target of measurement. For this reason, errors are unavoidable in measurement in units of 0.1 seconds. In addition, there are individual differences in operating the stopwatch, so the measured training clock is not always accurate. As a specific example, each horse racing newspaper's forecast paper contains a runner's training clock, but the training clocks that appear vary depending on the forecast paper, and in some cases a time that differs by more than 1 second. Is posted. If it differs by more than 1 second, it will be different by more than 10m in distance, and this will not only be useful for making predictions of the race, but it may also generate false predictions.

  In addition, the conventional automatic measurement can solve the above-mentioned measurement error problem of manual measurement, but it is necessary to install a large gate and bar code reader in the course, and it is premised on systematic operation. However, it cannot be used personally or simply for some racehorses or individual racehorses.

  Furthermore, the conventional automatic measurement method is difficult to apply to the present Baba. In other words, the width of the runway is as wide as about 15 meters or more, and it is difficult to install gates for attaching bar code readers to all courses. It can easily be seen that it is not practical to install a number of bar code readers side by side to read a bar code. In addition, when training on an actual racetrack course other than the training center, providing multiple gates with bar code readers on the racetrack course is a problem in terms of landscape in addition to the long width of the runway. It is also undesirable and more difficult and is not a more realistic method.

  As described above, the current automatic measurement method can only be applied to an extremely limited course or place such as a slope course.

  In addition, in the conventional automatic measurement, the training is usually performed in the early morning, but it is dim in the winter and the barcode may not be read and a measurement error may occur. Furthermore, since the racehorse that runs at a high speed as described above is the subject of measurement, and because the distance between the bar code reader provided at the gate and the racehorse is far away, the direction of the bar code may be slightly shifted. In the present situation, if a foreign matter covers even a part of the barcode, it is not recognized and a measurement error often occurs.

  The present invention solves the above problems and measures the time when the racehorse travels 200 m, 400 m, 600 m,... From the goal, regardless of the position where the racehorse travels (passes) inside or outside the training course. It is an object of the present invention to provide a measuring device and a measuring method for a racehorse training clock.

  Further, the present invention provides a measurement device for a racehorse training clock that can measure a training clock more accurately and personally without the need to install large-scale equipment and devices, regardless of the course of training. An object is to provide a measurement method.

  In order to achieve the above object, the present inventor first discovered a method using GPS as a measuring method for a new racehorse training clock. When using GPS, position data can be acquired using a satellite by attaching a GPS receiver to the racehorse or its rider, and moving speed can be obtained by periodically acquiring this. Therefore, there is an advantage that it is not necessary to arrange a facility such as a gate or a barcode reader in the training course.

  Furthermore, as a result of earnest research to obtain a training clock as an actually measured distance of a training place with reference to the goal, the present inventor has obtained a training course from position data of a racehorse obtained by using GPS every predetermined time. Based on the goal plate (Halon rod), a method of obtaining a running time of 200 m (1 halon), 400 m (2 halon), 600 m (3 halon),. That is, the present invention relates to the following (1) to (12) racehorse training clock measuring devices and measuring methods.

(1) A racehorse training clock measuring device,
Position data acquisition means for acquiring position data of the racehorse at a predetermined cycle using GPS;
A movement trajectory determining means for arranging an acquisition point on a plane based on the position data acquired at the predetermined cycle and drawing a movement trajectory line by connecting these points,
A training course inner periphery arranging means for arranging the inner periphery of the training course on the plane,
Reference position arrangement means for arranging the position of the goal's halon rod on the plane as a reference position for measuring the training time provided adjacent to the inner periphery of the training course;
First reference point determination means for obtaining, as a first reference point, an intersection of a perpendicular extending from the inner periphery of the training course and the movement trajectory line through the reference position;
A first acquisition point determination means for obtaining a pair of acquisition points closest to both sides of the first reference point as a first acquisition point and a second acquisition point;
A second reference point determining means for obtaining a position returned from the first reference point by a predetermined distance on the movement trajectory line as a second reference point;
Second acquisition point determination means for determining a pair of acquisition points closest to both sides of the second reference point as a third acquisition point and a fourth acquisition point;
The ratio of the distance between the first reference point and the first acquisition point or the second acquisition point to the distance between the first acquisition point and the second acquisition point, and the third acquisition point and the fourth acquisition point. The ratio of the distance between the second reference point and the third acquisition point or the fourth acquisition point with respect to the distance to the acquisition point is obtained, and one period for acquiring the position data is divided by these ratios. A correction time determining means for obtaining a correction time; and the number of acquisition points between the first reference point and the second reference point, the acquisition cycle of the position data, and the correction time, and the first reference point and the second reference point. An apparatus for measuring a racehorse training clock, characterized by comprising time calculation means for calculating a time required for the racehorse to move between the reference points.

  According to the racehorse training clock measuring device of (1) above, the position information of the racehorse that moves (runs) using GPS (Global Positioning System) is time-sequentially at a predetermined cycle (every fixed time). Because the racehorse or the training rider only needs to install a small device, there is no need to install any special equipment or equipment in the training course. Regardless of whether the train is trained by traveling on the inner side, the center, the outer side or the like, the trained clock can be measured as the time for each actually measured halon, whether traveling diagonally or meandering.

  The position data in the present invention is data indicating the latitude and longitude for specifying the place where the racehorse is located, and in addition thereto, time data may be added. When adding time data, the time data included in the GPS signal may be used, or for example, a clock means for measuring time may be provided. When the time data is added, the date / time information can be obtained from the time data, so that the history of the training clock (training data) can be managed in total.

  As the predetermined period in the present invention, a shorter period is preferable, and more specifically, it is preferably set to 1 second or less. For example, if the position data of the racehorse is sequentially acquired every 1 second period, the training clock can be measured as time in seconds. Naturally, the shorter the cycle, the more accurate the time can be measured.

  In the present invention, “placement points on a plane based on position data acquired at a predetermined cycle and draw a movement trajectory line by connecting them” is conceptually acquired in time series at a predetermined cycle. From the obtained position data, the position (acquisition point) at which the position data was acquired is plotted on a plane (on the map), and the trajectory of the racehorse moved by connecting these acquisition points with a straight line (movement trajectory line) ).

  In the present invention, “arranging the inner periphery of the training course on the plane” means, for example, line data (a set of position data) of the inner periphery (inner lattice) of the training course from map data or drawing data of the training course. This means that, based on this line data, the inner periphery of the training course is drawn on a plane. At this time, it is not necessary to draw the entire inner periphery of the training course, and it is sufficient to draw at least the inner periphery in the vicinity of the goal position. The map data, drawing data, and line data of the training course can be used, for example, stored in advance in the storage means of the measuring device or acquired from the Internet.

  In the present invention, the position of the goal's halon rod serving as the reference position is the position of the halon rod indicating the position of the goal provided on the inner periphery of the training course, and is a measurement standard on one side of the training clock in the present invention. It refers to the position on the plane of the position. Therefore, in the present invention, “the position of the goal's halon rod serving as a reference position for measuring the training time provided adjacent to the inner periphery of the training course is arranged on the plane” conceptually. This means that, on the plane, the position of the halon rod indicating the position of the goal provided at the inner periphery of the training course is plotted based on the position data. The position data for plotting the position of the halon rod indicating the position of the goal can be used after being previously acquired using a GPS receiver and stored in the storage means of the measuring apparatus. Moreover, if the position data of the target part in or near some training courses can be known, other reference position data can be estimated from the drawing data and map data of the training course.

  In the present invention, the “perpendicular line extending from the inner periphery of the training course through the reference position” means, for example, as shown in FIG. 1, the goal position G that is the reference position on the inner periphery (inner lattice) 100 of the training course TC. It is the perpendicular 110 with respect to the said inner periphery 100 drawn toward the outer periphery (outer lattice) 200 of the training course TC. Since the inner peripheral edge 100 is provided as a straight line, the vicinity of the goal position G can be obtained as a line 110 passing through the goal position G and perpendicular to the inner peripheral edge 100. In the present invention, the intersection point between the perpendicular line 110 passing through the reference position G and extending from the inner peripheral edge of the training course and the movement trajectory line is obtained as the first reference point. That is, the intersection of the perpendicular 110 and the movement trajectory line is plotted on a plane.

  Then, on the plane, on both sides of the first reference point on the movement trajectory line, a pair of first acquisition points and second acquisition points closest to the first reference point are obtained, and these first acquisition points and While calculating | requiring the distance (length) between 2nd acquisition points, the distance between the said 1st reference point and a 1st acquisition point or the distance between a 1st reference point and a 2nd acquisition point is calculated | required. Next, the distance between the first reference point and the first acquisition point with respect to the distance between the first acquisition point and the second acquisition point or the distance between the first reference point and the second acquisition point The ratio is obtained, and one period (predetermined period) for acquiring the racehorse position data is apportioned at this ratio, and the acquisition point (the front side of the goal in the training course) from the first reference point (perpendicular line 110) ( The time required for the racehorse to travel between the first or second acquisition points) is determined as the correction time.

  On the other hand, on the movement trajectory line, a position returned from the first reference point by a predetermined distance, for example, 200 m, 400 m, 600 m, etc. (the movement trajectory side that goes back in time), that is, the first reference point is regarded as a goal passing point. Then, a point a predetermined distance before the goal is obtained as the second reference point. That is, in the present invention, the time required for the racehorse to travel between the first reference point and the second reference point is measured.

  When the second reference point is obtained, a pair of third acquisition points closest to the second reference point on both sides of the second reference point on the movement trajectory line, as in the case of the first reference point, and While obtaining the fourth acquisition point and obtaining the distance (length) between the third acquisition point and the fourth acquisition point, the distance between the second reference point and the third acquisition point or the second reference point And the fourth acquisition point, and then the distance between the second reference point and the third acquisition point relative to the distance between the third acquisition point and the fourth acquisition point, or the second The ratio of the distance between the reference point and the fourth acquisition point is obtained, and one period (predetermined period) for acquiring the racehorse position data is apportioned at this ratio, and the rear side (training course) from the second reference point. The time required for the racehorse to travel between the acquisition points (third or fourth acquisition points) on the goal side) is determined as the correction time.

  For example, the front side of the first reference point is the first acquisition point and the rear side is the second acquisition point, and the distance between the first acquisition point and the first acquisition point is the distance between the first acquisition point and the second acquisition point. The distance ratio is 0.5, on the other hand, the front side of the second reference point is the third acquisition point and the rear side (goal side) is the fourth acquisition point, and the distance between the third acquisition point and the fourth acquisition point Assuming that the ratio of the distance between the second reference point and the fourth acquisition point to 0.3 is 0.3, and 1 cycle (predetermined cycle) for acquiring the position data of the racehorse is 1 second, the first reference point The correction time on the side (goal side) is 0.5 × 1 second = 0.5 seconds, and the correction time on the second reference point side is 0.3 × 1 second = 0.3 seconds.

  Next, the number of acquisition points existing between the first reference point and the second reference point is obtained, and the time is calculated from this number and the acquisition cycle (predetermined cycle) of the position data, and then this calculated By adding the correction time on the first reference point side and the correction time on the second reference point side calculated as described above to the time, the racehorse can move between the first reference point and the second reference point. Calculate the time required to move. Specifically, for example, if the acquisition cycle is 1 Hz (1 second) and there are 14 acquisition points including these reference points between the first reference point and the second reference point, first (14− 1) pieces × 1 second = 13 seconds are calculated, and the correction time on both sides (the first reference point side and the second reference point side), for example, the above 0.5 seconds and 0.3 seconds are added to the result. , It can be measured as 13 + 0.5 + 0.3 = 13.8 seconds when traveling 200m before the goal point.

  The “inner periphery of the training course” in the present invention is a straight road that is not a circulation type training course like a donut shape (track shape) like the slope course in the training center of the current Central Horse Racing. This is a concept that includes one side edge of the training course in the case of the training course. Moreover, in the present training center, a plurality of track-shaped training courses are provided so as to overlap inside and outside, and the halon rods indicating the goals in each training course are set up substantially in a straight line. In this case, the perpendicular extending from the inner periphery of the training course that passes through the reference position (goal position) is on the same line in any training course, so the inner periphery of the training course where the training was performed and its goal Therefore, the position of the inner periphery of the training course adjacent to the inside or outside of the training course or the position of the halon stick of the goal can be substituted, and the present invention includes such a case.

It is explanatory drawing for demonstrating the measurement reference line used as the object of the measurement distance of the training clock in Example 3 of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  Referring to FIG. 2, the measurement device for the training clock according to the first embodiment includes a measurement computer 10 and a GPS receiver 14 built in the computer as a measurement unit (position data acquisition device), and an analysis unit (time An analysis computer 20 is included as a measurement device. Although not shown, the measurement computer 10 is connected to an antenna for receiving GPS data and includes a driving battery (battery).

  Here, the measurement computer 10 and the analysis computer 20 are separate computers. However, a single computer may be provided with both functions. Alternatively, the GPS receiver 14 may be separated from the measurement computer 10 and the position data received by the GPS receiver may be transferred or transmitted to the measurement computer.

  The measurement computer 10 is attached to a rider (a jockey) or a racehorse, for example, a torso for measuring position data. As the measurement computer 10, various computers can be widely used. For example, a small or portable computer such as a PDA (personal digital assistant) can be preferably used. When using a PDA, the size is about 12 x 6 x 1 cm or less, and the weight is about 150 g or less, making it compact and lightweight, reducing the burden of training a racehorse or rider, and generating accidents such as injuries. Can be prevented.

  The measurement computer 10 includes a CPU 11, a ROM 12, a RAM 13, a GPS receiving unit 14, a data transmitting unit 15, and the like. The ROM 12 stores control programs and necessary data in advance, and the RAM 13 serves as a work memory and a buffer memory. The used and generated data, the acquired data, etc. are temporarily stored, and the GPS receiving unit 14 receives position data (latitude data, longitude data and time data) from a GPS satellite in a predetermined cycle and stores them in the ROM 12 or RAM 13. The data transmission unit 15 transfers the position data acquired (received) by the GPS reception unit 14 to the analysis computer 20 via the dedicated cable 30. The position data can also be transmitted to the analysis computer 20 by wireless communication. In this case, the data transmission unit can be eliminated, and the position data is transferred from the measurement computer 10 to the analysis computer 20 via the storage medium. May be.

  The GPS receiver 14 is position detecting means for detecting the current position of the racehorse, and receives a signal from a GPS satellite, for example, at a predetermined period of 1 Hz (every fixed time). Position data including coordinates (latitude data and longitude data) of the current position is output to the CPU 11. Here, the position data includes altitude data and time data by an electronic clock mounted on a GPS satellite in addition to latitude data and longitude data. Further, the position data may include horse identification data for identifying the racehorse. The identification data can be input and registered in advance in the measurement computer 10. Furthermore, date information may be included in the time data.

  Note that a reader for reading horse identification data (ID) in a non-contact manner from an ID chip embedded in the horse body of the racehorse is built in the measurement computer 10, and the ID information and the position data are used for the measurement computer 10. Or if it records and analyzes with the computer 20 for analysis, it will become unnecessary to input the identification data of a racehorse separately.

  The measurement computer 10 records the position data received by the GPS receiver 14 in the ROM 12, RAM 13 or memory dedicated to data storage. The coordinates as position data are stored in association with the acquisition time (date and time) and / or racehorse identification data.

  The recorded position data is transferred (transmitted) from the measurement computer 10 to the analysis computer 20 and taken into the analysis computer 20. As described above, the position data is stored in the measurement computer 10 with a portable storage medium, temporarily stored therein, and the storage medium is mounted in the analysis computer 20 and read by the analysis computer 20. You may make it take in.

  The analyzing computer 20 is for analyzing position data, measuring (analyzing) and outputting a training clock as a training result of the racehorse. As the analysis computer 20, for example, a personal computer can be used. The analysis computer 40 includes a CPU 21, ROM 22, RAM 23, HDD 24, data receiving unit 25, input unit 26, output unit 27, and the like. The ROM 22 stores a control program (including an analysis program) and necessary data in advance. The RAM 23 is used as a work memory and a buffer memory, and temporarily stores generated data and read data. The HDD 24 records position data, analysis data, and the like. The data receiver 25 receives the position data acquired by the measurement computer 10 from the data transmitter 15. The input unit 26 is a keyboard or the like, and the output unit 27 is an image display device, a printer, or the like for outputting a training result (clock), a trajectory that the racehorse has moved, and the like.

  In the analysis computer 20, the goal board in each training course, the latitude data, longitude data and altitude data position information (coordinates) of each halon bar, and map information of the training course are stored in the ROM 22 or the HDD 24 in advance.

  Next, an example of the operation of the measuring apparatus according to the first embodiment will be described with reference to FIG.

  First, position data is measured (acquired) at predetermined intervals (every predetermined time) by the measurement computer 10 attached to the racehorse or the rider and stored sequentially (step S11). In other words, the position data during the training follow-up in a predetermined training course is sampled by the GPS receiver 14 every second (1 Hz), for example, and the sampled position data is recorded in the measurement computer 10 as needed. Note that the shorter (smaller) the measurement cycle is, the more accurate the training clock can be analyzed and measured.

  Next, when the training follow-up is completed and the measurement of the position data is completed, the data transmission unit 15 of the measurement computer 10 is connected to the data reception unit 25 of the analysis computer 20 via the dedicated cable 30 to obtain the position data. The data is taken into the analysis computer 20. This position data can be imported by wireless transmission after measurement is completed by communication via the Internet, or after every measurement or at a predetermined timing, and the position data is stored in a memory card or the like. It can also be performed by storing the data in a medium and causing the analysis computer 20 to read position data from the storage medium.

  When the acquisition of the position data is completed, the analysis computer 20 performs the analysis. First, as shown in FIG. 4A, based on the position data, the position at the time of each data acquisition is sequentially plotted on the plane coordinates as the acquisition points 101, and these acquisition points 101 are connected by a straight line to move the race track 300 of the racehorse. (See FIG. 4B) is drawn (step S12). Next, the inner peripheral edge (inner lattice) 100 of the training course TC is drawn on the plane coordinates (step S13). The line data (position data) for drawing the inner peripheral edge 100 may be stored in advance in the storage means (ROM 22 or the like) of the analysis computer 20.

  On the other hand, as shown in FIG. 1 or FIG. 4 (B), the position G of the goal long rod of the training course TC to be the measurement reference position is plotted on the plane coordinates based on the reference position data stored in advance ( Step S14). Each of the training courses TC has a halon stick (halon stick G of goal, 1 halon stick 1H, 2 halon stick, 3 halon stick, etc.) every 200 m (1 halon) along and along the inner periphery 100. .) Is installed, and the reference position data of the goal's halon rod G among them is preliminarily used, for example, by using the measurement computer 10 or the GPS receiver which is the position data acquisition device of the present invention in advance in the training course. It can be measured and stored in the storage means of the analysis computer 20.

  Then, a perpendicular 110 (see FIG. 1 and FIG. 4 (B)) with respect to the inner peripheral edge 100 extending from the inner peripheral edge 100 to the outer peripheral edge 200 of the training course TC through the position G (reference position) of the goal's halon rod is drawn. The intersection of the perpendicular 110 and the movement trajectory line 300 is obtained as the first reference point X1 (step S15). When the first reference point X1 is obtained, as shown in FIG. 4B, the first acquisition point Y1 and the second acquisition point Z1 that are closest to each other on both sides of the first reference point X1 are obtained (step S16). ).

  Further, a position traced back from the first reference point X1 by a predetermined distance, for example, 200 m, is obtained as the second reference point X2, and the second reference point X2 is the same as the first reference point X1. As shown in FIG. 4B, the third acquisition point Y2 and the fourth acquisition point Z2 that are closest to each other on both sides of the second reference point X2 are obtained (steps S17 and S18).

  Then, a pair of the first acquisition point Y1 and the second acquisition point Z1 that are closest to the first reference point X1 and the second reference point X2, respectively, the third acquisition point Y2, the fourth acquisition point Z2, and the first acquisition point Y2. The ratio of the distance (length) between the reference point X1 or the second reference point X2 is obtained, and the correction time is obtained by the product of the ratio and the position data acquisition cycle (1 Hz = 1 second) (step S19). Specifically, the first reference point X1 will be described. As shown in FIG. 4C, conceptually, the first acquisition point Y1 adjacent to the first reference point X1 adjacent to the first reference point X1 and the first The distance (line segment y1 + z1) between the two acquisition points Z1 is calculated from the position data (latitude / longitude data) of the acquisition points Y1 and Z1, while the distance between the first acquisition point Y1 and the first reference point X1. The distance (line segment y1) is calculated similarly. And the distance (between Y1-X1) between the 1st acquisition point Y1 and the 1st standard point X1 to the distance (distance between Y1-Z1) between the 1st acquisition point Y1 and the 2nd acquisition point Z1. Find the ratio of (distance). Since the distance between the 1st acquisition point Y1 and the 2nd acquisition point Z1 is the distance which the racehorse moved in 1 period (for example, 1 second), if it divides 1 period with the ratio concerned, the 1st acquisition will be carried out. The time required for the racehorse to move (run) the distance between the point Y1 and the first reference point X1 can be obtained. For example, one cycle is 1 second (1 Hz), and the ratio of the distance between the first acquisition point Y1 and the first reference point X1 to the distance between the first acquisition point Y1 and the second acquisition point Z1 is 0. If it is 4, the racehorse has moved between the first acquisition point Y1 and the first reference point X1 (goal point) in 1 second × 0.4 = 0.4 second. Similarly, the second reference point X2 will be described. As shown in FIG. 4D, conceptually, the third acquisition point Y2 adjacent to the second reference point X2 on the plane coordinates and the fourth acquisition are obtained. The distance between the point Z2 (line segment y2 + z2) is calculated from the position data (latitude and longitude data) of the acquisition points Y2 and Z2, while the distance between the fourth acquisition point Z2 and the second reference point X2 ( The line segment z2) is calculated similarly. The distance between the fourth acquisition point Z2 and the second reference point X2 (between Z2 and X2) with respect to the distance between the third acquisition point Y2 and the fourth acquisition point Z2 (distance between Y2 and Z2). Find the ratio of (distance). Then, if one cycle is apportioned with this ratio, the time required for the racehorse to move (run) the distance between the second reference point X2 and the fourth acquisition point Z2 can be obtained. For example, one cycle is 1 second (1 Hz), and the ratio of the distance between the fourth acquisition point Z2 and the second reference point X2 to the distance between the third acquisition point Y2 and the fourth acquisition point Z2 is 0. If it is 7, it means that the racehorse has moved between the second reference point X2 and the fourth acquisition point Z2 in 1 second × 0.7 = 0.7 seconds.

  4A and 4B, the number of acquisition points 101 between the first reference point X1 and the second reference point X2, and the first acquisition point Y1 and the first reference point. The time required for the racehorse to move (run) the distance between the point X1 and the racehorse to move (run) the distance between the second reference point X2 and the fourth acquisition point Z2. The time required to move a predetermined distance (for example, 200 m) from the second reference point X2 to the first reference point X1 is obtained by the correction time, which is the required time, and is output to the output unit 27 (step S20). ).

  Specifically, the number of acquisition points (for example, 11) existing between the first reference point X1 and the second reference point X2 is obtained, and the time is calculated from this number and the acquisition cycle of the position data, Next, at this calculated time, the time required for the racehorse to move (run) the distance between the first acquisition point Y1 and the first reference point X1 calculated as described above, and The time required for the racehorse to move (run) the distance between the second reference point X2 and the fourth acquisition point Z2 is added to the second reference point X2 from the goal position which is the first reference point X1. It is possible to calculate the time required for the racehorse to move in the period up to (a measured predetermined distance (for example, 200 m) before the goal where the racehorse ran). In the above example, if the number of acquisition points existing between the first reference point X1 and the second reference point X2 is 11 and one period is 1 second, (11-1) × 1 second = 10 Second is the time required to move the distance between the first acquisition point Y1 and the fourth acquisition point Z2, and this is the distance between the first acquisition point Y1 and the first reference point X1 (goal point). Add 0.4 seconds, which is the time required to move the distance, and 0.7 seconds, which is the time required to move the distance between the second reference point X2 and the fourth acquisition point Z2. For example, it is possible to calculate the time required for the racehorse to move through the actual measurement 200m between the first reference point X1 (goal) and the second reference point X2, that is, 10 + 0.4 + 0.7 = 11.1 seconds. it can.

  In the same manner as described above, the time required for the racehorse to travel the actually measured travel distances 400 m, 600 m,... To the first reference point X1 (goal) is obtained, and these are output to the output unit 27 as a training clock. In addition, a training course (map) and a trajectory of the racehorse that has traveled on the training course (acquisition points or a movement trajectory line connecting the acquisition points or an approximate curve obtained by approximating the acquisition points) are also output. 27.

  Next, another example of the operation of the measuring device for a training clock according to the present invention will be described as a second embodiment with reference to FIG. The hardware configuration of the measuring apparatus is the same as that of the first embodiment, and is denoted by the same reference numerals in the following description.

  First, the measurement computer 10 measures (acquires) position data at a predetermined cycle and sequentially stores it (step S21). In other words, the position data during the training follow-up in a predetermined training course is sampled by the GPS receiver 14 every second (1 Hz), for example, and the sampled position data is recorded in the measurement computer 10 as needed. Note that the shorter (smaller) the measurement cycle is, the more accurate the training clock can be analyzed and measured.

  Next, when the training follow-up is completed and the measurement of the position data is completed, the measurement computer 10 is connected to the analysis computer 20 via the dedicated cable 30 and the position data is taken into the analysis computer 20. This position data can be imported by wireless transmission after measurement is completed by communication via the Internet, or after every measurement or at a predetermined timing, and the position data is stored in a memory card or the like. It can also be performed by storing the data in a medium and causing the analysis computer 20 to read the position data from the storage medium.

  When the acquisition of the position data is completed, the analysis computer 20 performs the analysis. First, as shown in FIG. 4A, the position at the time of each data acquisition is sequentially plotted as the acquisition point 101 on the plane coordinates based on the position data, and as shown in FIG. Based on the curve approximation, the approximate curve 400 is drawn (step S23). Next, the inner peripheral edge (inner lattice) 100 of the training course TC is drawn on the plane coordinates (step S23). The line data (position data) for drawing the inner peripheral edge 100 may be stored in advance in the storage means (ROM 22 or the like) of the analysis computer 20.

  On the other hand, as shown in FIG. 1 or FIG. 6 (A), the position G of the goal long rod of the training course TC as the measurement reference position is plotted on the plane coordinates based on the reference position data stored in advance ( Step S24). Each of the training courses TC has a halon stick (halon stick G of goal, 1 halon stick 1H, 2 halon stick, 3 halon stick, etc.) every 200 m (1 halon) along and along the inner periphery 100. .) Is installed, and the reference position data of the goal's halon rod G among them is preliminarily used, for example, by using the measurement computer 10 or the GPS receiver which is the position data acquisition device of the present invention in advance in the training course. It can be measured and stored in the storage means of the analysis computer 20.

  Then, a perpendicular line 110 (see FIG. 1 and FIG. 6A) with respect to the inner peripheral edge 100 extending from the inner peripheral edge 100 of the training course TC to the outer peripheral edge 200 through the position G (reference position) of the goal's halon rod is drawn. The intersection of the perpendicular 110 and the approximate curve 400 is obtained as the first reference point X3 (step S25). When the first reference point X3 is obtained, as shown in FIGS. 6A and 6B, a pair of acquisition points Y3 ′ and Z3 ′ that are closest to each other on both sides of the first reference point X3 are obtained. The acquisition point Y3 ′ and the acquisition point Z3 ′ are projected closest to the approximate curve 400 to obtain the first acquisition point Y3 and the second acquisition point Z3 (step S26).

  Also, the approximate curve 400 is obtained from the first reference point X1 by a predetermined distance, for example, 200 m, as a second reference point X4, and the second reference point X4 is the same as the first reference point X3. 6 (A) and 6 (B), a pair of acquisition points Y4 ′ and Z4 ′ that are closest to each other on both sides of the second reference point X4 is obtained, and acquisition points Y4 ′ and Z4 ′ are obtained. To the approximate curve 400 to obtain the third acquisition point Y4 and the fourth acquisition point Z4 (steps S27 and S28).

  Then, on each of the first reference point X3 side and the second reference point X4 side, the first acquisition point Y3 and the second acquisition point Z3, the third acquisition point Y4 and the fourth acquisition point Z4, and the first reference point X3. Alternatively, the ratio of the distance (length) of the approximate curve 400 to the second reference point X4 is obtained, and the correction time is obtained by the product of the ratio and the position data acquisition cycle (1 Hz = 1 second) (step S29). Specifically, the first reference point X3 side will be described. As shown in FIG. 6B, conceptually, an approximation between the first acquisition point Y3 and the second acquisition point Z3 on the plane coordinates. The distance (line segment y3 + z3) of the curve 400 is calculated from the position data (latitude and longitude data) of the acquisition points Y3 and Z3, and the distance of the approximate curve 400 between the first acquisition point Y3 and the first reference point X3. (Line segment y3) is calculated similarly. And between the first acquisition point Y3 and the first reference point X3 with respect to the distance of the approximate curve 400 between the first acquisition point Y3 and the second acquisition point Z3 (distance of the approximate curve 400 between Y3-Z3). The ratio of the distance of the approximate curve 400 (distance of the approximate curve 400 between Y3 and X3) is obtained. Since the distance between the first acquisition point Y3 and the second acquisition point Z3 can be regarded as the distance traveled by the racehorse in one cycle (for example, 1 second), the one cycle is divided by the ratio. For example, the time required for the racehorse to move (run) the distance between the first acquisition point Y3 and the first reference point X3 can be obtained. For example, one cycle is 1 second (1 Hz), and the ratio of the distance between the first acquisition point Y3 and the first reference point X3 to the distance between the first acquisition point Y3 and the second acquisition point Z3 is 0. Assuming 5, the racehorse has moved between the first acquisition point Y3 and the first reference point X3 (goal point) in 1 second × 0.5 = 0.5 seconds. Similarly, the second reference point X4 side will be described. As illustrated in FIG. 6C, conceptually, a pair of third acquisition points Y4 and fourth adjacent to the second reference point X4 on the plane coordinates are arranged. The distance (line segment y4 + z4) of the approximate curve 400 to the acquisition point Z4 is calculated from the position data (latitude and longitude data) of the acquisition points Y4 and Z4, while the fourth acquisition point Z4 and the second reference point X4 Similarly, the distance (line segment z4) of the approximate curve 400 is calculated. Then, between the fourth acquisition point Z4 and the second reference point X4 with respect to the distance of the approximate curve 400 between the third acquisition point Y4 and the fourth acquisition point Z4 (distance of the approximate curve 400 between Y4-Z4). The distance ratio (distance of the approximate curve 400 between Z4 and X4) is obtained. Then, if one period is apportioned by this ratio, the time required for the racehorse to move (run) the distance between the second reference point X4 and the fourth acquisition point Z4 can be obtained. For example, one cycle is 1 second (1 Hz), and the ratio of the distance between the fourth acquisition point Z4 and the second reference point X4 to the distance between the third acquisition point Y4 and the fourth acquisition point Z4 is 0. If it is 7, it means that the racehorse has moved between the second reference point X4 and the fourth acquisition point Z4 in 1 second × 0.7 = 0.7 seconds.

  Then, as shown in FIGS. 4A and 6A, the number of acquisition points 101 between the first reference point X3 and the second reference point X4, and the first acquisition point Y3 and the first acquisition point Y3. The racehorse moves (runs) the time required for the racehorse to move (runs) the distance between the first reference point X3 and the distance between the second reference point X4 and the fourth acquisition point Z4. The time required for moving a predetermined distance (for example, 200 m) from the second reference point X4 to the first reference point X3 is obtained by the correction time, which is the time required for this, and is output to the output unit 27 ( Step S30).

  Specifically, the number of acquisition points (for example, 11) existing between the first reference point X3 and the second reference point X4 is obtained, and the time is calculated from this number and the acquisition cycle of the position data, Next, in this calculated time, the time required for the racehorse to move (run) the distance between the first acquisition point Y3 and the first reference point X3 calculated as described above, and The time required for the racehorse to move (run) the distance between the second reference point X4 and the fourth acquisition point Z4 is added to the second reference point X4 from the goal position which is the first reference point X3. It is possible to calculate the time required for the racehorse to move in the period up to (a measured predetermined distance (for example, 200 m) before the goal where the racehorse ran). In the above example, if the number of acquisition points existing between the first reference point X3 and the second reference point X4 is 11 and one period is 1 second, (11-1) × 1 second = 10 Second is the time required to move the distance between the first acquisition point Y3 and the fourth acquisition point Z4, and this is the distance between the first acquisition point Y3 and the first reference point X3 (goal point). Add 0.5 seconds, which is the time required to move the distance, and 0.7 seconds, which is the time required to move the distance between the second reference point X4 and the fourth acquisition point Z4. For example, the time required for the racehorse to move 200 m between the first reference point X3 (goal) and the second reference point X4, that is, 10 + 0.5 + 0.7 = 11.2 seconds can be calculated. it can.

  In the same manner as described above, the time required for the racehorse to travel the actually measured travel distances 400 m, 600 m,... To the first reference point X1 (goal) is obtained, and these are output to the output unit 27 as a training clock. In addition, a training course (map) and a trajectory of the racehorse that has traveled on the training course (acquisition points or a movement trajectory line connecting the acquisition points or an approximate curve obtained by approximating the acquisition points) are also output. 27.

It may be constant.

  More specifically, as shown in FIG. 7, each of the training courses TC is provided with a halong stick G indicating the position of the goal along and adjacent to the inner peripheral edge 100, while the training course TC Each of the outer peripheral edge (outer lattice) 200, or along the inner peripheral edge of another training course provided outside or inside the training course TC, and adjacent to the inner peripheral edge of the training course TC, the goal long rod G of the inner peripheral edge 100 A line-of-sight halon bar G ′ or a halon bar G ′ of a goal of another training course is arranged at a position opposite to the straight line 110 ′, and a straight line 110 ′ connecting these opposed halon bars is used in place of the vertical line 110.
