Description

【0001】
【発明の属する技術分野】
本発明は、光信号の受信によって物体の部位を検知する受光位置検知装置に関し、特に、射撃シミュレーション装置などにおいて、車両の受光部位を検知する受光位置検知装置に関するものである。
【0002】
【従来の技術】
複数の受光素子を物体に帯状に配列し、それらの何れかがレーザ光線や近赤外光線や可視光線などの光信号を受信した場合、その受光素子を検出することによって、その物体が受光している部位を特定することができる。あるいは、送信側から見れば、物体のどの部位に光信号を送信したかを特定することができる。例えば、射撃シミュレーション装置で使用される車両の受光位置検知装置は、車両の全側面に帯状の受信器を装着し、その受信器に配列されている受光素子の番号によって、車両のどの部位が受光したかを判定している。通常、このような受信器は、絶縁物である布などに複数の受光素子を均等に配列して構成されている。
尚、以下の説明では、受光素子が光信号を受信または受光すると表現した場合は、受信と受光は全て同義語であるものとする。
【0003】
図4は、従来より射撃シミュレーション装置で使用されている車両と受光位置検知装置の配置模式図であり、(a)は車両の側面図、(b)は車両における受光素子の配列図を示す。同図において、車両(以下、A車両という)102の側面全周に亘って受信器103が装着されている。そして、この受信器103には均等な間隔で受光素子1〜16が配列されている。これによって、何れか1個または2個の受光素子が光信号を受光することによって、A車両102の受光部位を特定することができる。
【0004】
【発明が解決しようとする課題】
しかしながら、A車両102の受信器103を、これより小さい車両に装着しようとすると、何れかの部分で折りたたまなければならず、例えば、受光素子3,4及び受光素子13,14が隠れてしまって、これらの受光素子が受光できない状態になってしまう。このため、本来なら、受光素子3,4が受光したときは、A車両102の右横前部が受光部位であると特定することができるが、小さい車両に装着することによって受光素子3,4が隠れてしまうので、受光素子番号と車両の部位との対応関係が変わってしまう。したがって、特定の受光素子が光信号を受光したとしても、車両の部位との対応関係が変わるため、車両の部位を正確に検知することができなくなってしまう。このような事情から、従来の受信器は、車両の大きさや長さに合わせて製作され、それぞれの車両毎に専用に用いられている。従って従来の受光位置検知装置は、車両毎の大きさに合った受信器を設計して製作してなければならず、コストが高くなるという問題点があった。
【0005】
本発明は、このような事情に鑑みてなされたものであり、その目的は、各車両専用の受信器を用意することなく、共用の受信器で各車両の受光部位を正確に検知することのできる受光位置検知装置を提供することにある。
【0006】
【課題を解決するための手段】
上記の課題を解決するために、本発明の受光位置検知装置は、物体の外周に沿って複数の受光素子が配列され、複数の受光素子の少なくとも1個が光信号を受信することにより、複数の受光素子の各々に定められた受光素子番号に基づいて、物体の部位を検知する制御手段を有する受光位置検知装置において、複数の受光素子のうち、物体の部位を検知する外周の長さに応じて、物体の外周に露出する受光素子のみを前記制御手段に電気的に接続する回路切替手段を備え、この回路切替手段によって接続された受光素子の受光素子番号に対応して、物体の部位を検知することを特徴とする。
【0007】
すなわち、本発明の受光位置検知装置によれば、物体の外周の長さに応じて、必要とする受光素子のみを制御手段に電気的に接続し、不要な受光素子を電気的に切り離すことができる。これによって、物体の部位に検出する受光素子は過不足なく物体の外周に配列されることになる。したがって、同じ受光位置検知装置を、予め定めた複数の物体の何れに装着しても、常に正確な部位を検知することができる。これによって、例えば、各車両の大きさに合わせた受光位置検知装置を開発したり用意したりする必要がなくなり、1種類の受光位置検知装置で複数種類の車両に装着することができる。したがって、受光位置検知装置の開発費や材料費などの経費の削減を図ることができると共に、メンテナンス等の人件費を削減することができる。さらに、共用の受光位置検知装置にすることにより、総合的な物品点数を減らすことができるので、故障率が低下すると共に、容易に代替品を適用することができるので、緊急時に対応するメンテナンスにも容易に対応することができる。また、この受光位置検知装置を射撃シミュレーション装置用の車両に用いれば、これらの車両の種類が変わっても同じ受光位置検知装置を使うことができるので、種々の目的にあった射撃シミュレーションに利用することができる。
【0008】
また、本発明の受光位置検知装置は、前記回路切替手段が、物体の外周に露出しない受光素子を前記制御手段から電気的に切り離すと共に、切り離された受光素子に隣り合う受光素子同士が互いに隣り合うように前記制御手段に対して電気的に接続することを特徴とする。
【0009】
すなわち、本発明の受光位置検知装置によれば、車両のパネル面などに予め定めた複数種類の車両の選択スイッチを設け、この選択スイッチで選択された車両に対応して、受光位置検知装置の回路切替手段を切り換えるようにすれば、容易に受光位置検知装置を複数種類の車両に装着替えすることができる。さらに、車両の選択スイッチと受光位置検知装置の回路切替手段とが連動して動作するようにすれば、一層、受光位置検知装置の装着替えが簡単になり、且つ装着ミスを防止することもできる。
【0010】
また、本発明の受光位置検知装置は、複数の受光素子のうち、隣り合う少なくとも2個の受光素子が同時に光信号を受信したときは、物体の部位を検知する第1の情報を出力し、複数の受光素子のうち、1個の受光素子が光信号を受信したときは、物体の部位を検知する第2の情報を出力することを特徴とする
【0011】
すなわち、本発明の受光位置検知装置によれば、例えば、隣り合う2個の受光素子が同時に光信号を受信したときは、「有効1」とする情報を出力して広い範囲で物体の部位が特定されていることを知らせ、1個の受光素子が光信号を受信したときは、「有効2」とする情報を出力して狭い範囲で物体の部位が特定されていることを知らせることができる。このような情報の利用方法によれば、射撃シミュレーション装置などにおいて、標的を絞り込む訓練などに利用することができる。
【0012】
【発明の実施の形態】
以下、図面を用いて、本発明における受光位置検知装置の実施の形態を説明する。図1は、本発明の実施の形態における、射撃シミュレーション装置で使用される車両と受光位置検知装置の配置模式図であり、(a)は車両の側面図、(b)は車両における受光素子の配列図を示す。すなわち、図1は、図4で示したA車両102より小さい車両(以下、B車両という)101の側面全周に、A車両102で用いた受信器103を折りたたんで装着した状態を示している。したがって、この実施の形態では、長さが異なる車両に共通の受信器を装着した場合の一例として、図4のA車両102と図1のB車両101に対して、共通の受信器103を装着した場合について説明する。
【0013】
先ず、図4のA車両102及び図1のB車両101のように、共用する車両のうち、長い車両(すなわち、A車両102)の全周に合わせて受信器103を製作する。このとき、受信器103を短い車両(すなわち、B車両101)に装着すれば、数個(例えば2個)の受光素子が不要になる。したがって、B車両101において不必要になる受光素子を、予め折りたたみ易い箇所を設定し、不要となる受光素子の信号ラインに切換回路を設け、信号ラインへの接続と遮断が随時できるようにする。
【0014】
このような構成によって、図1におけるB車両101には、A車両102で用いた受信器103が、受光素子3,4及び受光素子13,14の部分で折りたたまれた状態で装着される。したがって、図1(b)のように、受光素子は1,2,5,6…11,12,15,16の順序で電気的に接続された状態で配列され、受光素子3,4及び13,14は、折りたたまれたときに電気的に開放されて受光素子番号が欠番状態となっている。
【0015】
図2は、本発明の実施の形態で用いられる受光位置検出装置における受光信号ラインの切換回路の構成図である。同図は、全ての受光素子の信号ライン及び切換回路を示す受光位置検出装置の構成図であるが、各スイッチによって切換えられた信号系統は、受信器103を図1のB車両101に装着した状態を示している。すなわち、図2における受光位置検出装置は、受光素子1,2,3,4,5,6…11,12,13,14,15,16の順序で全受光素子が配列されているが、B車両101に装着されることによって折りたたまれる位置にある受光素子3,4及び13,14は、電気的に回路から切り離されるようにスイッチが設けられている。
【0016】
さらに詳しく述べれば、受光位置検出装置の回路構成は、受光素子1,2,3,4がCPU111に接続されているが、受光素子3,4は、それぞれ、スイッチS4,S5によってCPU111から切り離しできるように構成されている。また、受光素子5,6,7,8はCPU112に直接接続されているが、受光素子5は、受光素子4への接続と受光素子2への接続との切り替えができるように、CPU111にはスイッチS6が設けられている。また、CPU112は、車両の反対側の受光素子を受け持つCPU113に接続されている。
【0017】
車両の反対側においては、受光素子9,10,11,12がCPU113に直接接続され、受光素子12が、受光素子13への接続と受光素子15への接続との切り替えができるように、CPU113にはスイッチS3が設けられている。また、受光素子13,14,15,16はCPU114に接続されているが、受光素子14,13は、それぞれ、スイッチS1,S2によってCPU114から切り離しできるように構成されている。そして、CPU114はCPU111と接続されている。
【0018】
このような回路構成によって、図4のように、受信器103がA車両102に装着されると、各スイッチの切換えによって、受光素子1,2,3,4,5,6…11,12,13,14,15,16の順序で全受光素子がCPU111〜114に接続される。そして、受光素子1,2,3,4の何れか1個または複数個が光信号を受光すると、CPU111によってその受光番号が読み取られて車両の部位が特定される。同様に、受光素子5,6,7,8の何れか1個または複数個が光信号を受光すると、CPU112によって受光番号が読み取られて車両の部位が特定される。車両の反対側の受光素子についても同様にして車両の部位を特定することができる。
【0019】
また、受信器103が図1のようにB車両101に装着されると、各スイッチは、図2に示す回路構成になるように切り替えられる。なお、スイッチはプログラムにより切り替え設定することができる。そして、受光素子3,4及び13,14がそれぞれのCPU111,114から切り離され、受光素子2が受光素子5に接続され、受光素子12が受光素子15に接続された状態となり、受光素子1,2,5,6…11,12,15,16の順序でCPUに接続される。
【0020】
次に、図1のように受信器103がB車両101に装着されたとき、各受光素子が正確な車両部位を検知する動作について説明する。図3は、受光素子番号に対応するA車両とB車両の部位を示す図表である。したがって、図1〜図4を用いてA車両とB車両における部位の検知動作について説明する。先ず、図4のA車両102に受信器103を装着すると、各スイッチの切換え動作によって全ての受光素子1,2,3,4,5,6…11,12,13,14,15,16はこの順序でCPU111〜114に接続される。
【0021】
したがって、図4(b)の受光素子の配列と図3の図表を参照すれば、A車両102は、受光素子1,2が受光したときは検出される車両部位は「右前」、受光素子3,4が受光したときは検出される車両部位は「右横前」、受光素子5,6が受光したときは検出される車両部位は「右横後」、受光素子7,8が受光したときは検出される車両部位は「右後」となり、車両の反対側(左側)についても、それぞれの受光素子が受光したときと車両部位との関係は図3の通りとなる。
【0022】
次に、図1のように、同じ受信器103を、A車両102より小さいB車両101に装着すると、各スイッチS1〜S6の回路は図2に示す系統のように自動的に切り替わる。これによって、B車両101における各受光素子の配列は図1(b)のようになる。すなわち、受光素子3,4及び13,14はCPUから切り離されているが、受光素子2の隣りに受光素子5が配列され、また、受光素子12の隣りに受光素子15が配列されている。
【0023】
したがって、図1(b)の受光素子の配列と図3の図表を参照すれば、B車両101は、受光素子1,2が受光したときは検出される車両部位は「右前」、受光素子2,5が受光したときは検出される車両部位は「右横前」、受光素子6,7が受光したときは検出される車両部位は「右横後」、受光素子7,8が受光したときは検出される車両部位は「右後」となり、車両の反対側(左側)についても、それぞれの受光素子が受光したときと車両部位との関係は図3の通りとなる。このように、同じ受信器を異なる大きさの車両に装着しても、各受光素子の受光によって、それぞれの車両毎に正確な部位を検出することができる。
【0024】
次に、1個の受光素子が受光した場合と、2個の受光素子が受光した場合について述べる。車両の受光位置判定は、上述の通り、受光した受光素子の番号で判定しているが、隣合う2つの受光素子に同時に受光信号が入力された場合は、「有効1」とする情報を出力し、1つの受光素子に受光信号が入力された場合は、「有効2」とする情報を出力している。すなわち、「有効1」は、車両の部位が広い範囲で検出されていることを示し、「有効2」は、車両の部位が狭い範囲で検出されていることを示している。このような部位の検出範囲を、例えば、射撃シミュレーションなどを利用すれば、標的を絞る訓練などに利用することができる。
【0025】
図3の図表を用いて一例を挙げれば、A車両102の場合は、受光素子1と受光素子2が受光すれば、受光部位は「右前」であり、判定は「有効1」となる。受光素子1のみが受光すれば、受光部位は「右前」であり、判定は「有効2」となる。また、受光素子16と受光素子1が受光した場合は、若い番号の部位を選択して、受光部位は「右前」であり、判定は「有効1」となる。
【0026】
次に、図1におけるB車両101のように、受信器を折りたためる場所を考慮すると、前述のように受光素子3,4及び受光素子13,14が不要になる。しかし、ただ単純に受光素子を折りたたんだだけでは隣合う受光素子が変わってしまい「有効1」の処理ができない場合がある。そこで、図2の様に、スイッチS1〜S6を用いて受光信号の配列順序を切り換えることによって、折りたたまれた受光素子3,4及び受光素子13,14が回路から切り離される。これによって図1(b)に示すように、B車両101を取り巻く有効な受光素子が隣合う様になり、全ての部位において「有効1」「有効2」の有効判定を行うことができる。
【0027】
例えば、図3の図表を用いて一例を挙げれば、B車両101の場合は、受光素子2と受光素子5が受光すれば、受光部位は「右横前」であり、判定は「有効1」となり、受光素子5のみが受光すれば、受光部位は「右横前」であり、判定は「有効2」となる。尚、受光素子16と受光素子1が受光した場合は、若い番号の部位を選択して、受光部位は「右前」であり、判定は「有効1」となることは、前述のA車両102の場合と同様である。
【0028】
尚、車両のパネル面などにA車両とB車両の選択スイッチを設けることにより、選択された車両に対応して、図2の受光位置検知装置の切り換え用のスイッチS1〜S6が同時に切り換わるように回路構成されている。さらに、各受光素子に入力される受光信号は、それぞれのCPUが入力時刻を管理しているので、隣り合う受光素子が同時に受光信号を入力した場合のみ「有効1」と判定する。したがって、異なる時刻に隣り合う受光素子に、順次、受光信号が入力された場合は、それぞれの時刻毎に受光した受光素子に対応する部位について「有効2」の判定を行う。
【0029】
尚、本発明の受光位置検知装置を射撃シミュレーション装置に適用することは、本発明の実施の形態の一例に過ぎないが、参考のために射撃シミュレーション装置の構成について概略説明する。すなわち、射撃シミュレーション装置は、情報を含んだ光信号(すなわち、レーザ光線、近赤外線光線、可視光線など)を送信できる送信器と、その送信器から送出される光信号を受信して電気信号に変換できる受信器と、この受信器からの電気信号を解析する制御器と、この制御器の解析結果に応じた光信号の受信信号を、音や光や発煙などによって表示することができる表示器とによって構成されている。そして、受信器側が車両に装着されて、送信器との間で相互に光信号の送受を行い、光信号の送信結果を判定したり評価したりすることができるシミュレーション装置となっている。
【0030】
そして、このような射撃シミュレーション装置において、車両のどの場所に受光したかを判定するために、車両全側面に帯状の受光器を装着して、受光素子番号に基づいて車両の受光位置の判定を行っている。そこで、本発明の受光位置検知装置を用いることによって、各車両専用の受光器を用いることなく、共用の受光器を用いて、予め定めた数種類の車両に装着すれば、複数種類の車両に応じた射撃シミュレーションを容易に行うことができる。
【0031】
以上述べた実施の形態は本発明を説明するための一例であり、本発明は、上記の実施の形態に限定されるものではなく、発明の要旨の範囲で種々の変形が可能である。例えば、上記の実施の形態では、受信器が受光素子3,4及び受光素子13,14の位置で折り曲げる場合について述べたが、これに限ることはなく、予め折り曲げる位置を設定しておけば、車両の大きさに合わせてそれぞれ所望の位置で折り曲げることもできる。また、前述の例では、受光位置検知装置を2種類の車両に適用する場合について述べたが、これに限ることはなく、それぞれ折り曲げる位置を決めておけば3種類以上の車両に適用することができることは言うまでもない。また、スイッチもハード構成のみならず、プログラムにより切り替えられるプログラマブルスイッチにより構成できることも言うまでもない。
【0032】
【発明の効果】
以上説明したように、本発明における受光位置検知装置によれば、各車両の大きさに合わせた受信器を開発したり用意したりする必要がなく、1種類の受信器で複数種類の車両に装着することができる。したがって、受光位置検知装置の開発費や材料費などの経費の削減を図ることができると共に、メンテナンス等の人件費を削減することができる。さらに、共用の受光位置検知装置にすることにより、総合的な物品点数を減らすことができるので、故障率が低下すると共に、容易に代替品を適用することができるので、緊急時に対応するメンテナンスにも容易に対応することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a light receiving position detecting device that detects a part of an object by receiving an optical signal, and more particularly to a light receiving position detecting device that detects a light receiving part of a vehicle in a shooting simulation apparatus or the like.
[0002]
[Prior art]
When a plurality of light receiving elements are arranged in a band on an object and one of them receives an optical signal such as a laser beam, a near infrared ray, or a visible ray, the object receives light by detecting the light receiving element. Can be identified. Alternatively, when viewed from the transmission side, it is possible to specify to which part of the object the optical signal is transmitted. For example, a vehicle light receiving position detection device used in a shooting simulation device has a belt-like receiver mounted on all sides of the vehicle, and which part of the vehicle receives light depending on the number of the light receiving element arranged in the receiver. Judgment is made. Usually, such a receiver is configured by arranging a plurality of light receiving elements evenly on an insulating cloth or the like.
In the following description, when it is expressed that the light receiving element receives or receives an optical signal, reception and light reception are all synonymous.
[0003]
4A and 4B are schematic diagrams of arrangement of a vehicle and a light receiving position detection device conventionally used in a shooting simulation device, in which FIG. 4A is a side view of the vehicle, and FIG. 4B is an array diagram of light receiving elements in the vehicle. In the figure, a receiver 103 is mounted over the entire side surface of a vehicle (hereinafter referred to as A vehicle) 102. In the receiver 103, the light receiving elements 1 to 16 are arranged at equal intervals. Thus, the light receiving portion of the A vehicle 102 can be specified by any one or two light receiving elements receiving the optical signal.
[0004]
[Problems to be solved by the invention]
However, if the receiver 103 of the A vehicle 102 is to be mounted on a smaller vehicle, it must be folded at any part, for example, the light receiving elements 3 and 4 and the light receiving elements 13 and 14 are hidden. As a result, these light receiving elements cannot receive light. Therefore, originally, when the light receiving elements 3 and 4 receive light, the right front part of the A vehicle 102 can be specified as the light receiving part. Is hidden, the correspondence between the light receiving element number and the vehicle part changes. Therefore, even if a specific light receiving element receives an optical signal, the correspondence with the vehicle part changes, so that the vehicle part cannot be accurately detected. Under such circumstances, the conventional receiver is manufactured according to the size and length of the vehicle, and is used exclusively for each vehicle. Therefore, the conventional light receiving position detection device has to be designed and manufactured in accordance with the size of each vehicle, and there is a problem that the cost is increased.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to accurately detect the light receiving portion of each vehicle with a common receiver without preparing a dedicated receiver for each vehicle. An object of the present invention is to provide a light receiving position detection device that can perform this.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problem, the light receiving position detection device of the present invention includes a plurality of light receiving elements arranged along the outer periphery of an object, and at least one of the plurality of light receiving elements receives an optical signal. In the light receiving position detecting device having a control means for detecting the object part based on the light receiving element number determined for each of the light receiving elements, the length of the outer periphery for detecting the object part among the plurality of light receiving elements is determined. Accordingly, a circuit switching means for electrically connecting only the light receiving elements exposed on the outer periphery of the object to the control means is provided, and the part of the object corresponding to the light receiving element number of the light receiving element connected by the circuit switching means. It is characterized by detecting.
[0007]
That is, according to the light receiving position detecting device of the present invention, only the required light receiving elements can be electrically connected to the control means and unnecessary light receiving elements can be electrically disconnected according to the length of the outer periphery of the object. it can. As a result, the light receiving elements to be detected at the site of the object are arranged on the outer periphery of the object without excess or deficiency. Therefore, even if the same light receiving position detection device is attached to any of a plurality of predetermined objects, an accurate site can always be detected. Accordingly, for example, it is not necessary to develop or prepare a light receiving position detection device that matches the size of each vehicle, and a single type of light receiving position detection device can be mounted on a plurality of types of vehicles. Accordingly, it is possible to reduce costs such as development costs and material costs of the light receiving position detection device, and it is possible to reduce labor costs such as maintenance. Furthermore, by using a common light receiving position detection device, the total number of articles can be reduced, so the failure rate is reduced and alternatives can be easily applied, so that maintenance can be performed in an emergency. Can also be easily accommodated. Further, if this light receiving position detecting device is used in a vehicle for a shooting simulation device, the same light receiving position detecting device can be used even if the type of these vehicles changes, so it is used for shooting simulations for various purposes. be able to.
[0008]
In the light receiving position detecting device of the present invention, the circuit switching means electrically disconnects the light receiving elements not exposed to the outer periphery of the object from the control means, and the light receiving elements adjacent to the separated light receiving elements are adjacent to each other. It is electrically connected to the control means so as to match.
[0009]
That is, according to the light receiving position detection device of the present invention, a plurality of types of vehicle selection switches that are determined in advance are provided on the panel surface of the vehicle, and the light reception position detection device of the light reception position detection device corresponds to the vehicle selected by the selection switch. If the circuit switching means is switched, the light receiving position detection device can be easily replaced with a plurality of types of vehicles. Further, if the vehicle selection switch and the circuit switching means of the light receiving position detecting device operate in conjunction with each other, it is possible to further easily change the mounting of the light receiving position detecting device and prevent a mounting error. .
[0010]
The light receiving position detecting device of the present invention outputs first information for detecting a part of an object when at least two adjacent light receiving elements among the plurality of light receiving elements simultaneously receive an optical signal, When one light receiving element among the plurality of light receiving elements receives an optical signal, the second information for detecting the part of the object is output.
That is, according to the light receiving position detection device of the present invention, for example, when two adjacent light receiving elements receive an optical signal at the same time, information indicating “effective 1” is output, and the part of the object is detected over a wide range. When one light receiving element receives an optical signal, it can notify that the part of the object is specified in a narrow range by outputting information “effective 2”. . According to such a method of using information, it can be used for training to narrow down a target in a shooting simulation apparatus or the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a light receiving position detection apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of the arrangement of a vehicle and a light receiving position detection device used in a shooting simulation apparatus according to an embodiment of the present invention, (a) is a side view of the vehicle, and (b) is a light receiving element of the vehicle. The sequence diagram is shown. That is, FIG. 1 shows a state in which the receiver 103 used in the A vehicle 102 is folded and mounted on the entire side surface of the vehicle 101 (hereinafter referred to as B vehicle) 101 smaller than the A vehicle 102 shown in FIG. . Therefore, in this embodiment, as an example of the case where a common receiver is attached to vehicles of different lengths, the common receiver 103 is attached to the A vehicle 102 in FIG. 4 and the B vehicle 101 in FIG. The case will be described.
[0013]
First, like the A vehicle 102 in FIG. 4 and the B vehicle 101 in FIG. 1, the receiver 103 is manufactured according to the entire circumference of the long vehicle (that is, the A vehicle 102) among the shared vehicles. At this time, if the receiver 103 is mounted on a short vehicle (that is, the B vehicle 101), several (for example, two) light receiving elements become unnecessary. Therefore, the light receiving elements that are unnecessary in the B vehicle 101 are set in advance at easy-to-fold locations, and a switching circuit is provided in the signal lines of the unnecessary light receiving elements so that connection to and disconnection from the signal lines can be performed as needed.
[0014]
With such a configuration, the receiver 103 used in the A vehicle 102 is attached to the B vehicle 101 in FIG. 1 in a state of being folded at the portions of the light receiving elements 3 and 4 and the light receiving elements 13 and 14. Therefore, as shown in FIG. 1 (b), the light receiving elements are arranged in the state of being electrically connected in the order of 1, 2, 5, 6... , 14 are electrically opened when folded, and the light receiving element numbers are missing.
[0015]
FIG. 2 is a configuration diagram of a light receiving signal line switching circuit in the light receiving position detecting device used in the embodiment of the present invention. This figure is a block diagram of the light receiving position detecting device showing the signal lines and switching circuits of all the light receiving elements. In the signal system switched by each switch, the receiver 103 is mounted on the vehicle B 101 in FIG. Indicates the state. That is, in the light receiving position detecting device in FIG. 2, all the light receiving elements are arranged in the order of the light receiving elements 1, 2, 3, 4, 5, 6... 11, 12, 13, 14, 15, 16. The light receiving elements 3, 4, 13, and 14 in a position where they are folded by being mounted on the vehicle 101 are provided with a switch so as to be electrically disconnected from the circuit.
[0016]
More specifically, in the circuit configuration of the light receiving position detecting device, the light receiving elements 1, 2, 3, and 4 are connected to the CPU 111, but the light receiving elements 3, 4 can be separated from the CPU 111 by switches S4 and S5, respectively. It is configured as follows. The light receiving elements 5, 6, 7, and 8 are directly connected to the CPU 112, but the light receiving element 5 is connected to the light receiving element 4 and the connection to the light receiving element 2 so that the CPU 111 can be switched. A switch S6 is provided. Further, the CPU 112 is connected to the CPU 113 that handles the light receiving element on the opposite side of the vehicle.
[0017]
On the opposite side of the vehicle, the light receiving elements 9, 10, 11, and 12 are directly connected to the CPU 113, so that the light receiving element 12 can be switched between connection to the light receiving element 13 and connection to the light receiving element 15. Is provided with a switch S3. The light receiving elements 13, 14, 15, and 16 are connected to the CPU 114. The light receiving elements 14 and 13 are configured to be separated from the CPU 114 by switches S1 and S2, respectively. The CPU 114 is connected to the CPU 111.
[0018]
With this circuit configuration, as shown in FIG. 4, when the receiver 103 is mounted on the A vehicle 102, the light receiving elements 1, 2, 3, 4, 5, 6... All the light receiving elements are connected to the CPUs 111 to 114 in the order of 13, 14, 15, and 16. When one or more of the light receiving elements 1, 2, 3 and 4 receive the optical signal, the CPU 111 reads the received light number and identifies the part of the vehicle. Similarly, when any one or more of the light receiving elements 5, 6, 7, and 8 receives the optical signal, the CPU 112 reads the light receiving number and specifies the part of the vehicle. Similarly, the part of the vehicle can be specified for the light receiving element on the opposite side of the vehicle.
[0019]
When the receiver 103 is mounted on the B vehicle 101 as shown in FIG. 1, the switches are switched so as to have the circuit configuration shown in FIG. The switch can be switched and set by a program. Then, the light receiving elements 3, 4 and 13, 14 are disconnected from the respective CPUs 111, 114, the light receiving element 2 is connected to the light receiving element 5, and the light receiving element 12 is connected to the light receiving element 15. 2, 5, 6... 11, 12, 15, 16 are connected to the CPU in this order.
[0020]
Next, an operation in which each light receiving element detects an accurate vehicle part when the receiver 103 is mounted on the B vehicle 101 as shown in FIG. 1 will be described. FIG. 3 is a chart showing parts of the A vehicle and the B vehicle corresponding to the light receiving element numbers. Therefore, the detection operation of the site | part in A vehicle and B vehicle is demonstrated using FIGS. 1-4. First, when the receiver 103 is mounted on the vehicle A in FIG. 4, all the light receiving elements 1, 2, 3, 4, 5, 6... 11, 12, 13, 14, 15, 16 are switched by the switching operation of each switch. The CPUs 111 to 114 are connected in this order.
[0021]
Therefore, referring to the arrangement of the light receiving elements in FIG. 4B and the chart in FIG. 3, the vehicle part A is detected as “front right” when the light receiving elements 1 and 2 receive light. When the light receiving elements 5 and 6 receive light, the detected vehicle part is “right front”, and when the light receiving elements 5 and 6 receive light, the detected vehicle part is “right rear right” and when the light receiving elements 7 and 8 receive light. The detected vehicle part is “right rear”, and the relationship between the light receiving element and the vehicle part on the opposite side (left side) of the vehicle is as shown in FIG.
[0022]
Next, when the same receiver 103 is attached to the B vehicle 101 smaller than the A vehicle 102 as shown in FIG. 1, the circuits of the switches S1 to S6 are automatically switched as shown in the system shown in FIG. Thereby, the arrangement of the light receiving elements in the B vehicle 101 is as shown in FIG. That is, although the light receiving elements 3, 4 and 13, 14 are separated from the CPU, the light receiving element 5 is arranged next to the light receiving element 2, and the light receiving element 15 is arranged next to the light receiving element 12.
[0023]
Therefore, referring to the arrangement of the light receiving elements in FIG. 1B and the chart in FIG. 3, the vehicle B detects that the vehicle part detected when the light receiving elements 1 and 2 receive light is “right front”, and the light receiving element 2 When the light receiving elements 6 and 7 receive light, the detected vehicle part is “front right”, and when the light receiving elements 6 and 7 receive light, the detected vehicle part is “right rear right” and when the light receiving elements 7 and 8 receive light. The detected vehicle part is “right rear”, and the relationship between the light receiving element and the vehicle part on the opposite side (left side) of the vehicle is as shown in FIG. Thus, even if the same receiver is mounted on vehicles of different sizes, it is possible to detect an accurate part for each vehicle by receiving light of each light receiving element.
[0024]
Next, a case where one light receiving element receives light and a case where two light receiving elements receive light will be described. As described above, the light receiving position of the vehicle is determined by the number of the received light receiving element. When a light receiving signal is simultaneously input to two adjacent light receiving elements, information indicating “valid 1” is output. When a light reception signal is input to one light receiving element, information indicating “effective 2” is output. That is, “effective 1” indicates that the vehicle part is detected in a wide range, and “effective 2” indicates that the vehicle part is detected in a narrow range. If such a part detection range is used, for example, by a shooting simulation, it can be used for training to narrow down the target.
[0025]
For example, in the case of the vehicle A 102, if the light receiving element 1 and the light receiving element 2 receive light, the light receiving part is “right front” and the determination is “effective 1”. If only the light receiving element 1 receives light, the light receiving part is “right front” and the determination is “valid 2”. When the light receiving element 16 and the light receiving element 1 receive light, a part with a lower number is selected, the light receiving part is “front right”, and the determination is “valid 1”.
[0026]
Next, considering the place where the receiver is folded, such as the B vehicle 101 in FIG. 1, the light receiving elements 3 and 4 and the light receiving elements 13 and 14 become unnecessary as described above. However, if the light receiving elements are simply folded, the adjacent light receiving elements are changed, and the “effective 1” process may not be performed. Therefore, as shown in FIG. 2, the folded light receiving elements 3 and 4 and the light receiving elements 13 and 14 are separated from the circuit by switching the arrangement order of the light receiving signals using the switches S1 to S6. As a result, as shown in FIG. 1B, the effective light receiving elements surrounding the B vehicle 101 are adjacent to each other, and “effective 1” and “effective 2” can be determined for all parts.
[0027]
For example, in the case of B vehicle 101, if the light receiving element 2 and the light receiving element 5 receive light, the light receiving part is “front right” and the determination is “valid 1”. If only the light receiving element 5 receives light, the light receiving portion is “right front” and the determination is “valid 2”. When the light receiving element 16 and the light receiving element 1 receive light, the part with the lower number is selected, the light receiving part is “right front”, and the determination is “valid 1”. Same as the case.
[0028]
It should be noted that by providing a selection switch for the A vehicle and the B vehicle on the panel surface of the vehicle, the switches S1 to S6 for switching the light receiving position detection device in FIG. 2 are simultaneously switched corresponding to the selected vehicle. The circuit configuration is as follows. Further, the received light signals input to the respective light receiving elements are determined to be “valid 1” only when the adjacent light receiving elements simultaneously input the received light signals because the respective CPUs manage the input times. Therefore, when light reception signals are sequentially input to adjacent light receiving elements at different times, “effective 2” is determined for the part corresponding to the light receiving element that receives light at each time.
[0029]
The application of the light receiving position detection device of the present invention to the shooting simulation device is only an example of the embodiment of the present invention, but the configuration of the shooting simulation device will be schematically described for reference. That is, the shooting simulation device receives a light signal including information (ie, a laser beam, a near infrared ray, a visible ray, etc.) and a light signal transmitted from the transmitter, and converts it into an electrical signal. Receiver that can be converted, controller that analyzes the electrical signal from this receiver, and indicator that can display the received signal of the optical signal according to the analysis result of this controller by sound, light, smoke, etc. And is composed of. And the receiver side is mounted on the vehicle, and it is a simulation device that can transmit and receive optical signals to and from the transmitter and determine and evaluate the transmission results of the optical signals.
[0030]
In such a shooting simulation apparatus, in order to determine where the light is received in the vehicle, a belt-like light receiver is attached to all sides of the vehicle, and the light receiving position of the vehicle is determined based on the light receiving element number. Is going. Therefore, by using the light receiving position detection device of the present invention, if it is mounted on several types of vehicles using a common light receiver without using a dedicated light receiver for each vehicle, it can be used for a plurality of types of vehicles. Shooting simulation can be performed easily.
[0031]
The embodiment described above is an example for explaining the present invention, and the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the invention. For example, in the above-described embodiment, the case where the receiver bends at the positions of the light receiving elements 3 and 4 and the light receiving elements 13 and 14 is described. However, the present invention is not limited to this. It can also be bent at a desired position according to the size of the vehicle. In the above-described example, the case where the light receiving position detection device is applied to two types of vehicles has been described. However, the present invention is not limited to this, and can be applied to three or more types of vehicles if the positions to be bent are determined. Needless to say, you can. Needless to say, the switch can be configured not only by a hardware configuration but also by a programmable switch that can be switched by a program.
[0032]

Furthermore, by using a common light receiving position detection device, the total number of articles can be reduced, so the failure rate is reduced and alternatives can be easily applied, so that maintenance can be performed in an emergency. Can also be easily accommodated.
