Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swim ID tag system used for managing the practice time of underwater exercises such as swimming and walking in water or for measuring competitions.

[0002]

2. Description of the Related Art Conventionally, a method for a swimmer to check the elapsed time (lap time) required for one round trip of a pool at the time of daily practice is to ask a cooperator such as a coach by the pool to time a stopwatch. Or, a general method was to prepare a large clock at the poolside and the swimmer would visually check the time each round trip to know the time.

[0003] In addition, a method for a swimmer to check the digestion status of a daily practice menu can be recorded by a cooperator such as a coach at the poolside or, if no cooperator is present, by the swimmer's own memory. The method of judging was common.

[0004]

SUMMARY OF THE INVENTION It is difficult for a swimmer to swim several thousand meters a day for practice to memorize the exact distance while swimming, and the coach always pays attention to only a specific swimmer. It was also difficult in practice. Furthermore, when practicing with a set target time, it is necessary to check a large clock or the like installed at a poolside or the like at every predetermined distance, and the practice is interrupted. In addition, it was virtually impossible for the swimmer to record the time each time, as the interruption time was further increased.

[0005]

In this way, the swimmer attaches the ID tag to the hand, the foot, or both,
The arrival of the swimmer can be automatically detected by the antenna. Therefore, it is possible to measure the time during practice without bothering others.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A swim ID tag system according to the present invention includes an ID tag attached to a part of a swimmer's body and transmitting a unique identification code, and an ID tag installed at a predetermined position in a swimmer's passage.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a swimmer 2 swimming in a pool 1 has an ID tag 3 attached to a wrist 201 and an ankle 202, respectively.
They are worn individually. Touch board 4 on pool end wall 101
The antenna 401 is built in the touch plate 4. The antenna 401 is connected to the
It is connected to the D detection device 5.

When the swimmer 2 approaches the pool end wall 101 and makes a turn, in the case of breaststroke or butterfly, the touch plate 4 is
Contact Freestyle, pool end wall 101 for backstroke
And kick the touch board 4 with your foot. At this time, the ID tag 3 attached to the wrist 201 or the ankle 202 of the swimmer 2 approaches the touch plate 4. The antenna 401 incorporated in the touch panel 4 receives a unique identification code transmitted by the ID tag 3 when the ID tag 3 approaches within a predetermined distance.

The ID detecting device 5 has a built-in clock mechanism. The ID detecting device 5 decodes the identification code received by the antenna 4 and detects the reception time at a predetermined interval, for example, every 50 msec to 200 msec. Then, when the swimmer 2 is separated from the touch panel 4 after the turn and cannot receive the identification code, the ID detection device 5 records the last detected reception time. The next time the same ID code is received, the ID detecting device 5 calculates and records the elapsed time (lap time) from the received time and the last detected time.

With the above configuration, in the case of a 50 m pool, the time of the swimmer 2 every 100 m is recorded in the ID detection device 5. Even when the swimmer 2 temporarily pauses near the touch panel 4, the recorded time is the net time of swimming away from the touch panel 4, so that the effect of the practice can be grasped more accurately. . Next, details of the ID detection device 5 will be described with reference to FIG.

The ID tag system according to the present embodiment has
The D tag does not include a battery or the like, but receives an electromagnetic wave supplied from the outside by a coil inside the ID tag 3 and stores the received electromagnetic wave in a capacitor, and transmits the identification code using the power. That is, the antenna 401 is used for both transmission and reception for supplying power and detecting an identification code. The transmission / reception switching cycle, transmission intensity, reception sensitivity, and the like are optimally controlled by the transmission / reception control circuit 501.

The received identification code is sent to an ID reading circuit 502
And checks whether it matches the identification code registered in advance. If a match can be confirmed, the time code of the timer circuit 503 is added to the identification code, and the identification code is output to the exercise / pause determination means 504 as arrival time information of the swimmer. The timer circuit 503 has at least one tenth of a second,
Desirably, the current time up to the hundredths of a second is counted, and every time an identification code is input to the ID detection circuit 502, the time at that time is counted by the ID detection circuit 50.
Output to 2.

The arrival time information from the ID detection circuit 502 is repeatedly output while the swimmer stays within the detection range of the antenna 401. Exercise / pause determination means 504
Determines that the swimmer is at rest while the arrival time information is being input. However, when the swimmer stays while moving his or her limbs, the identification code cannot be detected depending on the positional relationship between the antenna 401 and the ID tag 3. In such a case, there is a risk that the swimmer may erroneously determine that the swimmer has begun to swim. In order to avoid such erroneous determination, it is determined that the swimmer has begun to swim only when the identification code has not been detected for a predetermined time. The determination condition setting means 505 can appropriately set the predetermined time according to the situation.

In the present embodiment, when used for ordinary swimming practice, the predetermined time is set to 10 seconds. That is, when there is no new arrival time information for 10 seconds, the last arrival time information is output to the lap time calculation means 507 as the swimmer's departure time. Next, the swimmer reciprocates in the pool and returns to the departure point, and the arrival time information when the identification code is first detected is output to the lap time calculation means 507. By subtracting the departure time from the arrival time, the current lap time is calculated.

The calculated lap time is output to lap time storage means 508. In addition, every time the lap time is calculated, 1 is added to the number-of-turns integrating means 511.
The lap time storage means 508 stores the past lap times for each swimmer, and can be called up and displayed as needed. The exercise time accumulation means 509 accumulates only the actual swim time of the swimmer by accumulating the lap times stored in the lap time storage means 508.

On the other hand, the pause time accumulating means 506 accumulates the time during which the swimmer is not swimming while staying near the antenna 401. The total time accumulation means 510 adds the contents of the exercise time accumulation means 509 and the pause time accumulation means 506,
Accumulate the time the swimmer has been in the pool. By comparing the contents of the total time accumulating means 510 and the contents of the exercise time accumulating means 509, it is possible to know the practice density of the swimmer.

The contents of the turn number accumulating means 511 are output to the exercise distance accumulating means 512. Exercise distance integrating means 51
In 2, information on the distance of a single copy of the pool is set in advance. For example, in the case of a 50 m pool, 100 m is added for each single copy. By setting in advance information relating to basal metabolic rate such as the swimmer's age, gender, and weight, and information relating to exercise intensity such as a swimming style and a form of swimming, the exercise time integrating means 509 and the exercise distance integrating means 512 are set. , The amount of energy consumed by exercise can be calculated by the exercise amount calculation means 513.

The individual swimmer's time information recorded in the ID detection device 5 is displayed on the display device 6 installed on the poolside 102.
Is displayed together with the swimmer's identification code number or name. The time information displayed on the display device 6 includes the last 10
The time can be switched as required, such as the time of 0 m or the accumulated time from the start of practice. In addition, the display device 6 has 3 to 4 so that information of a plurality of swimmers can be displayed at the same time.
It is designed to be stacked.

The counting device 7 is connected to the ID detecting device 5 and the display device 6, and counts and stores time information output from the ID detecting device 5 in an arbitrary format. For example, a practice menu of a swimmer's day is input in the tallying device 7 in advance, and the difference between the target time set in the practice menu and the time actually recorded in the ID detecting device 5 by swimming is calculated each time. It can also be displayed on the display device 6.

The tallying device 7 can register a practice menu for one month of the swimmer and automatically set a daily practice menu based on the digestion status of the practice menu. In such a case, it is convenient for the swimmer if a printer (not shown) prints the practice menu of the day on paper. Of course, it is also possible to appropriately adjust the strength of the training content with respect to the training menu set by the tallying device 7 according to the physical condition of the swimmer on the day.

Further, records of all the players belonging to the swimming school, for example, are stored in the counting device 7, and the coach can periodically check the stored contents.
These stored records can be effectively used as basic data when setting a practice menu for each player according to their ability. The swimming ID tag system of the present invention can be applied not only to training but also to a timing system in competitions. In that case, it is necessary to consider a predetermined time correction. That is, the antenna 401 normally receives the identification code when the ID tag 3 approaches a predetermined distance, for example, about several tens of centimeters, and predicts and adds a time corresponding to the predetermined distance. In this case, it is desirable to reduce the time correction value by intentionally lowering the sensitivity of the antenna 401 by the antenna sensitivity adjustment mechanism and reducing the distance for receiving the identification code as much as possible.

Alternatively, the swimming ID tag system of the present invention can be applied not only to the time measurement itself but also to an auxiliary system of another time measurement system. The timing system currently used generally detects the timing of arrival by the swimmer pressing a touch board with a built-in mechanical switch, but the touch board is not accidentally activated by a person other than the swimmer As described above, the hold function for disabling the operation of the touch panel for a predetermined time is provided. The hold function is manually released or released by a built-in timer, but there are various difficulties in releasing the hold function at an optimum timing for each swimmer in setting the timer or in the manual operation. If the hold function is released when the antenna receives the identification code of the swimmer's ID tag, the hold function can be released at an optimum timing of several 10 cm before the touch plate.

The swimming ID tag system of the present invention can be applied not only to practice or competition in a pool but also to practice or competition in so-called open water such as a river, a lake, or the sea. In this case, the antenna is not limited to the type with a built-in touch plate as shown in the embodiment, but may be of various types such as a gate-shaped antenna or a buoy.

In the present embodiment, the ID tag is described in the form of transmitting the identification code only when power is accumulated from the external power transmitting antenna to the capacitor built in the ID tag, but the type is not particularly limited. . For example,
All types can be applied, such as a type that has a built-in power source and constantly transmits an identification code, and a type that includes only passive elements. The medium that transmits the identification code is not only radio waves,
It may be an optical signal such as infrared light or visible light, or an ultrasonic wave.

The antenna for receiving the identification code can be selected from a loop-shaped antenna, a rod-shaped antenna, a parabolic antenna and the like depending on the application of the present invention.

The present invention is embodied in the form described above and has the following effects. Receives an ID tag attached to a part of the swimmer's body and transmitting a unique identification code, and a unique identification code installed at a predetermined position in the swimmer's passage and transmitted by the ID tag when the ID tag approaches a predetermined distance. By providing an antenna that detects the swimmer's arrival by performing the operation, and an ID detection device that decodes the unique identification code received by the antenna and records and outputs the individual swimmer's time information, the antenna automatically detects the swimmer's arrival. Because it is possible to detect the time, it is possible to measure the time during the practice and to total the time without bothering others.

Further, by providing exercise time integrating means and pause time integrating means in the ID detecting device, it is possible to more specifically grasp the exercise density and effect. In addition, it is possible to obtain information on exercise physiology such as energy metabolism consumed by the exercise.
