Description

本発明は、赤外線等の光を発する投光器と、この光を受ける受光器とで構成される光線式センサーの光軸調整機能に関するものである。 The present invention relates to a function of adjusting an optical axis of a light beam sensor including a projector that emits light such as infrared rays and a light receiver that receives the light.

光線式センサーは、投光器と受光器を所定の距離だけ離して設置するものである。投光器から受光器に達する光の強さは、雨や霧等の気象条件や、装置のカバーや窓部の汚れによる減衰を考慮し、余裕を持った値としてある。例えば１ ０ ０ ｍ の距離を警戒する装置の場合、受光器側の受光信号レベルが最大時の１ ／ １ ０ ０ まで減衰しても検知信号を発しない程度にするのが一般的である。光線式センサーの性能を発揮させるために、投光ユニットと受光ユニットを、それぞれ対応するユニットに向けて正確に光軸調整する必要がある。受光器に受光レベルを出力する受光量出力部を設け、その出力値をテスターで確認しながら受光ユニットの方向を調整したり、専用の双方向無線通信モジュール内蔵光軸調整ユニットを、投光器と受光器の両方に接続し、光軸調整を行ったりしている。（例えば特許文献１参照）
特開２０１０−１６６３４１号公報 The light beam sensor is a device in which a projector and a light receiver are separated by a predetermined distance. The intensity of light reaching the light receiver from the projector is a value having a margin in consideration of weather conditions such as rain and fog, and attenuation due to dirt on the cover and windows of the apparatus. For example, in the case of a device that warns about a distance of 1 0 0 m, it is general that the detection signal is not generated even if the light reception signal level on the light receiver side is attenuated to 1/100 at the maximum. In order to demonstrate the performance of the light sensor, it is necessary to accurately adjust the optical axis of the light projecting unit and the light receiving unit toward the corresponding units. The receiver is equipped with a received light amount output unit that outputs the received light level, and adjusts the direction of the light receiving unit while checking the output value with a tester, or the dedicated optical axis adjustment unit with built-in bidirectional wireless communication module The optical axis is adjusted by connecting to both. (For example, see Patent Document 1)
JP 2010-166341 A

光線式センサーの設置作業者や警報時に駆けつける警備員などのすべてが、テスターや専用の双方向無線通信モジュール内蔵光軸調整ユニットなどの機器を常時所持しているとは限らない。そのため、光軸調整時に精度よく調整がなされず不安定な警戒状態により誤報が多発したり、正しくメンテナンスできなかったりすることがあった。 Not all operators, such as light sensor installation workers and security guards who run at alarms, always have devices such as testers and dedicated optical axis adjustment units with built-in bidirectional wireless communication modules. For this reason, the optical axis is not adjusted with high accuracy, and there are cases in which false alarms frequently occur due to an unstable alert state or maintenance cannot be performed correctly.

上記課題を解決するため、本発明は、光線式センサーの受光器に、スマートフォンやタブレット端末などの多機能携帯端末装置と無線通信可能な機能を内蔵もしくは外付け可能とし、特定の多機能携帯端末装置で受光器の受光量出力部の出力値を確認できるようにし、受光器に無線通信モジュールと、無線通信モジュールのペアリング開始用スイッチとを内蔵し、前記ペアリング開始用スイッチを運用時に使用するカバー内に配置する。 In order to solve the above-described problems, the present invention enables a photosensor of a light sensor to have a built-in or externally attachable function capable of wireless communication with a multi-function mobile terminal device such as a smartphone or a tablet terminal. The device can check the output value of the received light amount output part of the receiver. The receiver has a built-in wireless communication module and a pairing start switch for the wireless communication module, and the pairing start switch is used during operation. Place it in the cover.

本発明により、一般的に普及している多機能携帯端末装置で、受光器の受光レベルを確認することができ、テスターや専用機器を常時所持していなくても光軸調整が精度よく行える。 According to the present invention, the light receiving level of the light receiver can be confirmed by a multi-functional portable terminal device that is generally spread, and the optical axis can be adjusted accurately even if the tester and the dedicated device are not always held.

本発明の１実施形態の構成を示した図である。It is the figure which showed the structure of one Embodiment of this invention.

以下、添付図面を参照して本発明の好ましい実施例について説明する。図１は本発明の実施形態の構成を示した図である。光線式センサーは、投光ユニット３を内蔵した投光器１と受光ユニット４を内蔵した受光器２で構成され、投光ユニット３から受光ユニット４へ、光を発し警戒区間を構成している。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing a configuration of an embodiment of the present invention. The light beam sensor includes a light projector 1 having a light projecting unit 3 and a light receiver 2 having a light receiving unit 4. The light sensor emits light from the light projecting unit 3 to the light receiving unit 4 to form a warning section.

受光器２にブルートゥース（登録商標）モジュール５とブルートゥースモジュール５のペアリング開始用スイッチ（図示せず）を内蔵する。受光器２に内蔵のペアリング開始用スイッチを押すことによりブルートゥースモジュール５がペアリング可能な状態となる。 The optical receiver 2 includes a Bluetooth (registered trademark) module 5 and a pairing start switch (not shown) for the Bluetooth module 5. When the pairing start switch built in the light receiver 2 is pressed, the Bluetooth module 5 becomes ready for pairing.

次に多機能携帯端末装置６でブルートゥース機器を探索し、ブルートゥースモジュール５を発見しペアリング処理を行い、多機能携帯端末装置６とブルートゥースモジュール５でデータ通信可能な状態とする。ブルートゥースモジュール５から、受光量出力部からの出力値を送信し、多機能携帯端末装置６で受光量表示部７を表示する。受光量表示部７の値を確認し、光軸調整を行う。 Next, the multi-function mobile terminal device 6 searches for Bluetooth devices, finds the Bluetooth module 5 and performs pairing processing, so that the multi-function mobile terminal device 6 and the Bluetooth module 5 can perform data communication. The output value from the received light amount output unit is transmitted from the Bluetooth module 5, and the received light amount display unit 7 is displayed on the multi-function portable terminal device 6. The value of the received light amount display unit 7 is confirmed, and the optical axis is adjusted.

ブルートゥースモジュール５からは受光量だけでなく、検知情報や検知反応速度などの光線式センサーの各種設定を送信し、多機能携帯端末装置６に表示できるようにしてもよい。また、図１ではブルートゥースモジュールを受光器に内蔵したが外付けにできるようにしてもよく、異なる無線通信モジュールとしてもよい。 From the Bluetooth module 5, not only the amount of received light but also various settings of the light sensor such as detection information and detection reaction speed may be transmitted and displayed on the multi-function portable terminal device 6. Further, although the Bluetooth module is built in the light receiver in FIG. 1, it may be made externally attached or may be a different wireless communication module.

さらに、ペアリング開始用スイッチを光線式センサー運用時には閉められているカバー内に配置することや、一定時間経過すると自動的にデータ通信を停止したりペアリングを削除したりすることや、カバーを閉めることによりデータ通信を停止したりペアリングを削除したりすることでセキュリティ性が高まる。 In addition, the pairing start switch can be placed inside a cover that is closed when the optical sensor is in operation, data communication can be automatically stopped or pairing can be deleted after a certain period of time, By closing, data communication is stopped or pairing is deleted, thereby increasing security.
