Description

本発明は、光信号の送信方向に誤りがあることを検出して、当該送信の中止及びユーザへの報知を行う機能を有する光信号送信装置に関する。   The present invention relates to an optical signal transmission apparatus having a function of detecting that there is an error in the transmission direction of an optical signal and canceling the transmission and notifying a user.

対象物に向けて光信号を送信する装置は種々な用途に用いることができ、例えば、移動する対象物に向けてレーザ光線等の光信号を発射して当該対象物を捕捉するゲーム等のシミュレーションシステムに用いることができる。
このようなシステムでは、光信号送信装置から光信号が送信されるまでの間、対象物が移動した場合でも、ユーザが光信号送信装置を当該対象物に向けた状態に維持する必要がある。 An apparatus that transmits an optical signal toward an object can be used for various purposes. For example, a simulation of a game or the like that captures an object by emitting an optical signal such as a laser beam toward the moving object. Can be used in the system.
In such a system, it is necessary for the user to keep the optical signal transmission device facing the target object even when the target object moves until the optical signal is transmitted from the optical signal transmission device.

光信号送信装置では、ユーザが光信号送信装置の送信スイッチを操作して所定時間が経過すると光信号が送信される。このため、光信号が送信されるまでの間に対象物が移動して、光信号送信装置が対象物に正しく向いていない状態でも光信号が送信されていた。
この結果、対象物から外れた方向へ光信号が送信されてしまうばかりか、ユーザが対象物へ正しく光信号が送信されたか否かを認識することができないという課題があった。 In the optical signal transmission device, an optical signal is transmitted when a predetermined time elapses after the user operates the transmission switch of the optical signal transmission device. For this reason, the optical signal is transmitted even in a state in which the object moves before the optical signal is transmitted and the optical signal transmission device is not properly directed to the object.
As a result, there is a problem that the optical signal is transmitted in a direction away from the object, and the user cannot recognize whether the optical signal is correctly transmitted to the object.

本発明は、上記従来の事情に鑑みなされたもので、上記課題を合理的に解決する光信号送信装置を提供することを目的としている。   The present invention has been made in view of the above-described conventional circumstances, and an object thereof is to provide an optical signal transmission apparatus that can reasonably solve the above-described problems.

本発明は、ユーザが自装置の向きを変更することにより、送信する光信号の方向を変更することができる光信号送信装置であり、基本的には、送信スイッチからユーザによる送信指示が入力されると、当該送信指示の入力から所定時間経過後に光信号を送信する。
そして、本発明の光信号送信装置では、この送信指示に基づいた光信号の送信処理において、光信号送信装置の変位に応じた送信制御を行う。 The present invention is an optical signal transmission apparatus in which a user can change the direction of an optical signal to be transmitted by changing the direction of the own apparatus. Basically, a transmission instruction by a user is input from a transmission switch. Then, an optical signal is transmitted after a predetermined time has elapsed from the input of the transmission instruction.
And in the optical signal transmitter of this invention, in the transmission process of the optical signal based on this transmission instruction | indication, transmission control according to the displacement of an optical signal transmitter is performed.

すなわち、光信号送信装置に設けられたセンサが自装置の変位を検出し、光信号送信装置に設けられた送信制御手段が、前記送信指示が入力された後の所定時間内で、センサで検出した変位が所定の基準値以内であるときは当該所定時間経過後に光信号を送信させ、センサで検出した変位が前記所定の基準値を上回るときは当該送信指示に基づいた光信号の送信を中止する。更に、光信号送信装置に設けられた報知手段が、光信号送信を中止したことに応じて、発光や鳴動等といった方法でユーザに対する報知情報を出力する。   That is, the sensor provided in the optical signal transmission device detects the displacement of the own device, and the transmission control means provided in the optical signal transmission device detects the displacement within a predetermined time after the transmission instruction is input. When the displacement is within a predetermined reference value, the optical signal is transmitted after the predetermined time has elapsed, and when the displacement detected by the sensor exceeds the predetermined reference value, the transmission of the optical signal based on the transmission instruction is stopped. To do. Furthermore, informing means provided in the optical signal transmission device outputs notification information to the user by a method such as light emission or ringing in response to the stop of optical signal transmission.

したがって、センサが変位の量（変位量センサ等）と割合（変位加速度センサ等）との少なくともいずれか一方により光信号送信装置の変位を検出し、変位が所定の基準値以内で光信号送信装置があまり大きく変位していない場合やあまり急激に変位していない場合に、光信号を発信して対象物への送信が正確になされるようにする。一方、変位が所定の基準値を上回って光信号送信装置が大きく変位した場合や急激に変位した場合には、光信号の送信を中止して、この送信中止を報知してユーザに認知させる。   Therefore, the sensor detects the displacement of the optical signal transmission device by at least one of the amount of displacement (displacement amount sensor, etc.) and the ratio (displacement acceleration sensor, etc.), and the optical signal transmission device falls within a predetermined reference value. When the lens is not displaced too much or when it is not displaced too rapidly, an optical signal is transmitted so that the transmission to the object is performed accurately. On the other hand, when the displacement exceeds a predetermined reference value and the optical signal transmission device is greatly displaced or suddenly displaced, the transmission of the optical signal is stopped, and the user is notified by notifying this transmission stop.

本発明に係る光信号送信装置によると、光信号送信装置の変位が大きい場合には光信号の送信を中止してユーザに報知するようにしたため、対象物から外れた方向への光信号送信を回避することができるとともに、ユーザに対象物へ正しく光信号が送信されたか否かを認知させることができる。   According to the optical signal transmission device according to the present invention, when the displacement of the optical signal transmission device is large, the transmission of the optical signal is stopped and the user is notified, so that the optical signal transmission in the direction away from the object is performed. In addition to being able to avoid this, the user can be made aware of whether or not the optical signal has been correctly transmitted to the object.

本発明に係る光信号送信装置を、実施例に基づいて具体的に説明する。
図１に示すように、本例の光信号送信装置１は、三脚２上にフレキシブルジョイント３を介して設けられており、上下左右及び斜め方向へ向きを変更して指向性の高い光信号（本例では、指向性の高い光信号であるレーザ光）の送信方向を自由に変更できるようになっている。
したがって、ユーザが手で操作して光信号送信装置１の向きを変更することにより、上下左右及び斜め方向へ自由に移動する受信体（対象物）４に向けて光信号を送信することができるようになっている。
なお、光信号送信装置１を上記のように三脚等に設置せずに、ユーザが光信号送信装置１を担持して操作するようにしてもよい。 The optical signal transmission apparatus according to the present invention will be specifically described based on examples.
As shown in FIG. 1, the optical signal transmission device 1 of this example is provided on a tripod 2 via a flexible joint 3, and changes its direction in the up / down / left / right and diagonal directions to provide a highly directional optical signal ( In this example, the transmission direction of a laser beam that is an optical signal having high directivity can be freely changed.
Therefore, when the user operates the hand to change the direction of the optical signal transmission device 1, the optical signal can be transmitted toward the receiver (object) 4 that freely moves in the up / down / left / right and diagonal directions. It is like that.
Note that the optical signal transmission device 1 may be carried and operated by the user without installing the optical signal transmission device 1 on a tripod or the like as described above.

図２に示すように、光信号送信装置１は、光信号を発振して送信する光信号送信部１０と、ユーザが送信指示を入力するための送信スイッチ１１と、当該光信号送信装置１の変位を検出するセンサ１２と、送信スイッチ１１からの送信指示に基づいて光信号送信部１０からの光信号の送信を制御する送信制御部１３と、送信指示に基づいた光信号送信を中止した場合に発光や鳴動による報知情報を外部へ出力する報知部１４と、を有している。   As shown in FIG. 2, the optical signal transmission device 1 includes an optical signal transmission unit 10 that oscillates and transmits an optical signal, a transmission switch 11 for a user to input a transmission instruction, and the optical signal transmission device 1. When the sensor 12 that detects the displacement, the transmission control unit 13 that controls the transmission of the optical signal from the optical signal transmission unit 10 based on the transmission instruction from the transmission switch 11, and the optical signal transmission based on the transmission instruction are stopped And a notification unit 14 for outputting notification information by light emission or ringing to the outside.

光信号送信部１０は、本例ではレーザ発振送信機であり、遠隔の受信体４へレーザ光信号を送信することができる。
送信スイッチ１１は、光信号送信装置１に設けられたボタン等の操作子であり、ユーザが光信号を送信しようとするときに操作してＯＮにする。
報知部１４は、後述するように送信制御手段１３からの指示に応じて、ＬＥＤの発光やブザーの鳴動等といった方法で光信号送信の中止を報知出力する。 The optical signal transmitter 10 is a laser oscillation transmitter in this example, and can transmit a laser light signal to the remote receiver 4.
The transmission switch 11 is an operator such as a button provided in the optical signal transmission device 1 and is operated to be turned on when the user intends to transmit an optical signal.
As will be described later, the notification unit 14 notifies and outputs the stop of the optical signal transmission by a method such as LED light emission or buzzer sounding in response to an instruction from the transmission control unit 13.

センサ１２は、方位角の変位量（すなわち、光信号送信装置１の水平面内での変位角）、斜角の変位量（すなわち、光信号送信装置１の垂直面内での変位角）、これら角度変位の速度を検出する３Ｄセンサであり、光信号送信装置１が上下左右及び斜め方向へ向きを変更された場合、センサ１２によって、光信号送信装置１の変位の量及び速度が検出される。
すなわち、センサ１２によって、光信号送信装置１の変位の大きさ及び激しさが検出される。 The sensor 12 includes an azimuth displacement amount (that is, a displacement angle in the horizontal plane of the optical signal transmission device 1), an oblique displacement amount (that is, a displacement angle in the vertical plane of the optical signal transmission device 1), and the like. This is a 3D sensor that detects the speed of angular displacement, and when the direction of the optical signal transmission device 1 is changed in the up / down / left / right and diagonal directions, the amount and speed of displacement of the optical signal transmission device 1 are detected by the sensor 12. .
That is, the sensor 12 detects the magnitude and severity of the displacement of the optical signal transmission device 1.

送信制御手段１３は、送信指示の入力から光信号の送信までの所定時間（例えば、２秒）が予め設定されており、基本的には、送信スイッチ１１から送信指示が入力されて当該所定時間が経過した後に、光信号送信部１０から光信号を送信させる。
また、送信制御手段１３は、センサ１２の検出対象に対応して、方位角の変位量、斜角の変位量、これら角度変位の速度に対する所定の基準値が予め設定されており、センサ１２で検出されたいずれかの値が当該所定基準値を上回るときには、上記の基本動作である送信指示に基づいた光信号の送信処理を中止する。 The transmission control means 13 is preset with a predetermined time (for example, 2 seconds) from the input of the transmission instruction to the transmission of the optical signal. Basically, when the transmission instruction is input from the transmission switch 11, the predetermined time After the elapse of time, the optical signal transmission unit 10 transmits an optical signal.
The transmission control means 13 is preset with predetermined reference values for the displacement amount of the azimuth angle, the displacement amount of the oblique angle, and the speed of these angular displacements corresponding to the detection target of the sensor 12. When any of the detected values exceeds the predetermined reference value, the optical signal transmission process based on the transmission instruction as the basic operation is stopped.

したがって、送信制御手段１３は、センサ１２で検出した変位が所定の基準値以内であるときは所定時間経過後に光信号を送信させ、センサ１２で検出した変位が所定の基準値を上回るときは送信指示に基づいた光信号の送信を中止する制御を行う。
すなわち、送信スイッチ１１から送信指示が入力された後の所定時間内で、移動する受信体４に追従させるために、光信号送信装置１が大きく変位された場合や変位の量が小さくても急激に変位された場合には、送信指示が入力されたにも拘らず、光信号送信装置１からの光信号の送信がなされず、報知部１４から報知情報が出力される。このため、受信体４に受信させることができない光信号の誤送信が回避され、このような送信中止がなされたことをユーザに認識させることができる。 Therefore, the transmission control means 13 transmits an optical signal after a predetermined time when the displacement detected by the sensor 12 is within a predetermined reference value, and transmits when the displacement detected by the sensor 12 exceeds the predetermined reference value. Control to stop transmission of the optical signal based on the instruction is performed.
That is, in order to make the moving receiver 4 follow within a predetermined time after the transmission instruction is input from the transmission switch 11, the optical signal transmission device 1 is suddenly displaced even when the displacement is small or the displacement amount is small. If the transmission instruction is input, the optical signal is not transmitted from the optical signal transmission device 1 despite the transmission instruction being input, and the notification information is output from the notification unit 14. For this reason, erroneous transmission of an optical signal that cannot be received by the receiver 4 is avoided, and the user can be made aware that such transmission has been stopped.

図３には、本例に係る光信号送信装置１の処理手順を示してある。
まず、ユーザは、光信号送信装置１を動かしてその向きを変更し、光信号送信装置１により受信体４に狙いが定まったところで送信スイッチ１１を操作してＯＮにする。
このように送信スイッチ１１がＯＮとされると（ステップＳ１）、送信制御手段１３が、初期設定処理を行ってセンサ１２をリセットし（ステップＳ２）、当該センサ１２の検出値（本例では、方位角の変位量、斜角の変位量、これら角度変位の速度）を監視し（ステップＳ３）、検出された検出値をセンサ１２から取得する（ステップＳ４）。 FIG. 3 shows a processing procedure of the optical signal transmission apparatus 1 according to this example.
First, the user moves the optical signal transmission device 1 to change the direction thereof, and when the optical signal transmission device 1 aims at the receiver 4, the user operates the transmission switch 11 to turn it on.
When the transmission switch 11 is thus turned on (step S1), the transmission control means 13 performs an initial setting process to reset the sensor 12 (step S2), and the detection value of the sensor 12 (in this example, The azimuth displacement, the oblique displacement, and the speed of these angular displacements are monitored (step S3), and the detected value is acquired from the sensor 12 (step S4).

そして、上記の所定時間が経過したところで（ステップＳ５）、送信制御手段１３が、センサ１２から取得した検出値と上記の所定基準値とを比較して、少なくともいずれか１つの検出値が所定基準値を上回るか（すなわち、異常時か）を判定する（ステップＳ６）。
この結果、全ての検出値が所定基準値以内である場合（すなわち、正常時）には、送信制御手段１３が光信号送信部１０から光信号を送信させる（ステップＳ７）。一方、いずれかの検出値が所定基準値を上回る場合（すなわち、異常時）には、送信制御手段１３が、光信号送信部１０からの光信号の送信を中止させるとともに報知部１４から報知情報を出力させる（ステップＳ８）。 When the predetermined time has elapsed (step S5), the transmission control means 13 compares the detection value acquired from the sensor 12 with the predetermined reference value, and at least one of the detection values is the predetermined reference. It is determined whether the value is exceeded (that is, when it is abnormal) (step S6).
As a result, when all the detected values are within the predetermined reference value (that is, when normal), the transmission control unit 13 causes the optical signal transmission unit 10 to transmit an optical signal (step S7). On the other hand, when one of the detected values exceeds a predetermined reference value (that is, when there is an abnormality), the transmission control unit 13 stops the transmission of the optical signal from the optical signal transmission unit 10 and the notification information from the notification unit 14. Is output (step S8).

したがって、受信体４を追尾するために光信号送信装置１が大きく向きを変えられたり或いは急激に向きを変えられたりした場合は、受信体４に光信号を送信して受信させることが困難な状態であるので、このような状態で誤った光信号の送信がなされることを回避することができ、当該送信回避をユーザに認知させることができる。   Therefore, when the direction of the optical signal transmission device 1 is greatly changed or the direction is changed suddenly in order to track the receiver 4, it is difficult to transmit the optical signal to the receiver 4 for reception. Since this is a state, it is possible to avoid erroneous transmission of an optical signal in such a state, and to allow the user to recognize the transmission avoidance.

なお、上記の例では、図４（ａ）に概念的に示すように、光信号送信装置１の角度変位（θ）に係る値をセンサ１２で検出したが、本発明では、同図（ｂ）に概念的に示すように、光信号送信装置１の位置変位（Ｄ）に係る値をセンサ１２で検出し、当該値に係る基準値を設定して、上記のような処理により、位置変位の量や速度（或いは、加速度）が基準値より大きい時には光信号の送信を中止する制御を行うようにしてもよい。   In the above example, as conceptually shown in FIG. 4A, the value related to the angular displacement (θ) of the optical signal transmission device 1 is detected by the sensor 12, but in the present invention, ) Conceptually, the sensor 12 detects a value related to the position displacement (D) of the optical signal transmission device 1, sets a reference value related to the value, and performs the above-described processing to position displacement. When the amount or speed (or acceleration) is greater than the reference value, control for stopping transmission of the optical signal may be performed.

また、上記の例では、光信号送信装置１の方位角の変位量、斜角の変位量、これら角度変位の速度のいずれか１つでも基準値を上回るときには光信号の送信を中止するようにしたが、これら検出値の任意の組み合わせが共に基準値を上回るときに光信号の送信を中止するようにしてもよく、このように積条件とすることで、光信号の送信中止をする制御条件をより厳格に設定するようにしてもよい。
また、センサ１２による検出値及び基準値は、上記の他に、角度変位の加速度、上下左右や前後の位置変位の量、これら位置変位の速度や加速度等といった種々な値を採用することができ、また、基準値を設定値の大きさも必要に応じて任意に設定されればよく、また、検出値の数や種類は任意に設定すればよく、要は、光信号の誤送信が生じてしまうような光信号送信装置１の挙動を判定し得るようにすればよい。 In the above example, when any one of the displacement amount of the azimuth angle, the displacement amount of the oblique angle, and the speed of the angular displacement of the optical signal transmission device 1 exceeds the reference value, the transmission of the optical signal is stopped. However, when any combination of these detected values exceeds the reference value, the transmission of the optical signal may be stopped. By using the product condition in this way, the control condition for stopping the transmission of the optical signal May be set more strictly.
In addition to the above, the value detected by the sensor 12 and the reference value may employ various values such as acceleration of angular displacement, amount of positional displacement in the vertical and horizontal directions, front and rear, and the speed and acceleration of these positional displacements. In addition, the reference value may be arbitrarily set according to need, and the number and type of detection values may be arbitrarily set. In short, an optical signal is erroneously transmitted. What is necessary is just to enable it to judge the behavior of the optical signal transmitter 1 which will end up.
