Description

【0001】
【発明の属する技術分野】本発明は、競技場等で特定のコースを複数の走者が周回するスピード競技において、走者の周回回数を計測管理する周回チェック装置に関する。
【0002】
【従来の技術】従来の方法は、IDタグにID番号データを送信させる為のトリガ(引き金)信号を送信するアンテナが走路を横切るように設置されていた。(例えば、特許文献 特願平6−222698 参照)
【0003】
【発明が解決しようとする課題】以上の従来技術によれば、走者が走る走路を横切るように、アンテナを設置する工事費用が大きかった。
【0004】また、走路の外側にトリガアンテナを設置すると、走路の反対側を通過する走者との距離が大きくなるので、トリガ送信部の送信出力を大きくしなければならず、大型の送信部が必要であった。
【0005】
【課題を解決するための手段】以上の課題を解決するため、請求項1の発明は、トリガ送信部を間欠発信させることで、大出力のトリガ送信部を小型に出来て、設置工事や変更工事を簡単に実現できる周回チェック装置を提供する。
【0006】トリガ送信部は、送信出力を大きくすると、それに比例して発熱量が増大し、放熱の機構が大きくなって、大型になるのが通例である。
そこで、送信出力を断続して間欠発信する事により、最大出力を大きくしても、平均出力が抑えられて、形状が大きくならないようにする方法である。
【0007】
【発明の実施の形態】発明の実施の形態を実施例にもとづき図面を参照して説明する。
図1の実施例では、トリガ送信装置が、間欠発信制御部31とトリガ送信部32及びトリガ送信アンテナ33で構成されている。
【0008】
走路11を走るIDタグを持った走者21〜25が、トリガ送信アンテナ33に近づくと、IDタグから各々固有のID番号が送信されて、受信装置のID受信アンテナ41〜42とID受信部43で受信されるID番号により、各々の走者がトリガ送信アンテナ33付近を通過した回数を周回表示部44で表示する。
【0009】トリガ送信部32は、数KHz〜数百KHzの信号を発生し、従来は間欠発信制御部31が無くて、図2の連続発信信号を出力していた。
【0010】連続発信では、例えば送信出力10Wで送信効率が50%とすると、平均で10Wの発熱が発生する。
走路の反対側まで届く距離を延ばすために、送信出力を4倍の40Wにすると、発熱量も4倍になって、放熱効果が4倍必要であり、形状が大きくなる。
【0011】本発明では、トリガ送信部を制御する間欠発信制御部31を設けて、例えば図2の間欠発信波形のように、1mS送信して3mS送信停止を繰り返すようにすると、平均出力は10Wになり、発熱量が1/4に抑えられて、放熱機構を大きくしなくても良い。
IDタグは、トリガ信号を受信したら、ID番号を発信するだけの動作であるから、連続発信でなくとも支障がなく、送信出力のピーク値が大きくなれば、受信可能な距離を大きく出来る。
【0012】
【発明の効果】以上説明したように、本発明によれば、競技場等で特定の走路を複数の走者が周回するスピード競技において、小型で設置し易い周回チェック装置を提供できる。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lap check device for measuring and managing the number of laps of a runner in a speed competition in which a plurality of runners make a round at a stadium or the like.
[0002]
2. Description of the Related Art In a conventional method, an antenna for transmitting a trigger (trigger) signal for transmitting ID number data to an ID tag is installed so as to cross a track. (See, for example, Patent Document No. 6-2222698)
[0003]
According to the above prior art, construction costs for installing an antenna so as to cross a runway on which a runner runs are high.
Further, if a trigger antenna is installed outside the track, the distance between the trigger antenna and the runner who passes on the opposite side of the track increases, so that the transmission output of the trigger transmitter must be increased. Was needed.
[0005]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention of claim 1 makes it possible to reduce the size of the large-output trigger transmission unit by intermittently transmitting the trigger transmission unit, thereby making it possible to perform installation work or change. To provide a lap check device that can easily realize construction.
When the transmission output is increased, the amount of heat generated in the trigger transmission section is increased in proportion to the transmission output, and the heat radiation mechanism is generally increased to increase the size.
Therefore, the transmission output is intermittently transmitted so that even if the maximum output is increased, the average output is suppressed and the shape is not increased.
[0007]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings.
In the embodiment of FIG. 1, the trigger transmission device includes an intermittent transmission control unit 31, a trigger transmission unit 32, and a trigger transmission antenna 33.
[0008]
When the runners 21 to 25 having the ID tags running on the runway 11 approach the trigger transmitting antenna 33, the ID tags respectively transmit unique ID numbers, and the ID receiving antennas 41 to 42 and the ID receiving unit 43 of the receiving device. The number of times each runner has passed the vicinity of the trigger transmission antenna 33 is displayed on the circling display unit 44 by the ID number received in the step (1).
The trigger transmission section 32 generates a signal of several KHz to several hundred KHz, and conventionally has no intermittent transmission control section 31 and outputs the continuous transmission signal of FIG.
In continuous transmission, for example, if the transmission efficiency is 50% at a transmission output of 10 W, an average of 10 W of heat is generated.
If the transmission output is quadrupled to 40 W in order to extend the distance reaching the opposite side of the runway, the amount of heat generated also increases four times, the heat radiation effect needs to be four times larger, and the shape becomes larger.
According to the present invention, an intermittent transmission control unit 31 for controlling the trigger transmission unit is provided. For example, as shown in the intermittent transmission waveform of FIG. The heat generation amount is suppressed to 1/4, and the heat radiation mechanism does not need to be large.
When the ID tag receives the trigger signal, the ID tag merely transmits the ID number. Therefore, there is no problem even if the ID tag is not continuously transmitted. If the peak value of the transmission output increases, the receivable distance can be increased.
[0012]
As described above, according to the present invention, it is possible to provide a small and easy-to-install lap check device in a speed competition in which a plurality of runners traverse a specific runway in a stadium or the like.
