Description

本発明は一時的に使用される場所を臨時に警戒すべき区域において、侵入者を検知するための超音波式検知装置に関するものである。 The present invention relates to an ultrasonic detection device for detecting an intruder in an area where a place to be temporarily used should be temporarily watched.

従来、侵入者を検知するために投光器と受光器とを対向して設置する赤外線式検知装置を警戒すべき区域の外周に配置し警戒を行っている。
赤外線式検知装置は、一般に特許文献１に記載されているように、投光器と受光器とをそれぞれポールに取り付けて対向させ、検知装置が十分な性能を発揮するためには受光レベルが最大になるように、照準器（例えば特許文献２）を用いて複数の投光部と受光部を上下左右に動かし、それぞれの光軸を調整する必要がある。 Conventionally, an infrared detection device in which a floodlight and a light receiver are installed facing each other in order to detect an intruder is placed on the outer periphery of an area to be watched for warning.
In an infrared detection device, as described in Patent Document 1, a floodlight and a light receiver are attached to poles to face each other, and the light reception level is maximized in order for the detection device to exhibit sufficient performance. As described above, it is necessary to use a sighting device (for example, Patent Document 2) to move a plurality of light emitting parts and light receiving parts up, down, left and right to adjust their respective optical axes.

しかしながら、警戒すべき区域は長期に使用される区域だけでなく、イベント会場や自衛隊の移動部隊の野営地などのように一時的に警戒が必要となることがあった。その場合、数百メートル離れていることもある投光部と受光部の光軸調整が必要なため、使用期間の割には設置時間がかかるという問題があった。また、自衛隊の移動部隊の野営地などでは迅速に設置する必要があり、正確な光軸調整ができず、不安定な警戒状態となる可能性があった。また、赤外線の下を匍匐前進された場合、侵入者を検知しない失報状態となる可能性があった。 However, areas to be watched are not limited to areas that are used for a long period of time, but there are cases where temporary caution is required, such as event venues and campsites for mobile units of the Self-Defense Forces. In that case, since it is necessary to adjust the optical axes of the light emitting part and the light receiving part, which may be several hundred meters apart, there is a problem that the installation time is long for the usage period. In addition, it was necessary to quickly install it in the campsites of the SDF's mobile units, and it was not possible to adjust the optical axis accurately, which could lead to an unstable alert state. In addition, when crawling under infrared rays, there was a possibility of a misreporting state in which an intruder was not detected.

上記課題を解決するために、本発明の超音波式検知装置は、超音波送波器と、超音波受波器と、前記超音波送波器を駆動させる送波部と、前記超音波受波器からの受波信号を受ける受波部と、前記受波部からの信号に基づき異常を検出する信号処理部と、前記信号処理部で異常を検出した時に警報信号を出力する出力部とからなる超音波センサーを、
一定の間隔で複数連結し、
保管時はロール状に巻くことができ、運用時は広げて設置を行えるようにした。 In order to solve the above problems, the ultrasonic detection device of the present invention includes an ultrasonic transmitter, an ultrasonic receiver, a transmitter for driving the ultrasonic transmitter, and an ultrasonic receiver. A receiving unit that receives a receiving signal from a wave device, a signal processing unit that detects an abnormality based on the signal from the receiving unit, and an output unit that outputs an alarm signal when an abnormality is detected by the signal processing unit. Ultrasonic sensor consisting of
Connect multiple at regular intervals,
It can be rolled into a roll during storage, and can be expanded and installed during operation.

本発明の検知装置は超音波式であるため、赤外線式とは異なり、光軸調整が不要であり、地面や床に置くだけで設置でき、設置時間の短縮につながる。また、ロール状で保管できるため、可搬性に優れている。また、広げるだけで設置が可能であるため、設置、撤収にかかる時間が短く、一時的な警戒区域に使用するのに便利である。また、地面から検知エリアができているため、侵入者が匍匐前進をしても検知することができ、失報になることはない。 Since the detection device of the present invention is an ultrasonic type, unlike an infrared type, it does not require optical axis adjustment and can be installed simply by placing it on the ground or floor, which leads to a reduction in installation time. Moreover, since it can be stored in a roll shape, it has excellent portability. In addition, since it can be installed simply by expanding it, the time required for installation and withdrawal is short, and it is convenient to use it in a temporary caution area. In addition, since the detection area is created from the ground, it can be detected even if an intruder moves forward, and there is no false report.

図３は本発明の超音波式検知装置の実施形態のブロック図である。
超音波式検知装置１には複数の超音波センサー１０を備えている。各超音波センサーは超音波送波器１１、超音波受波器１２、送波部１３、受波部１４、信号処理部１５、出力部１６で構成されている。 FIG. 3 is a block diagram of an embodiment of the ultrasonic detection device of the present invention.
The ultrasonic detection device 1 is provided with a plurality of ultrasonic sensors 10. Each ultrasonic sensor is composed of an ultrasonic wave transmitter 11, an ultrasonic wave receiver 12, a wave transmitting unit 13, a receiving unit 14, a signal processing unit 15, and an output unit 16.

送波部１３において、超音波送波器１１から超音波を送波させるための信号を発生させ、侵入者により反射した超音波を超音波受波器１２で受波し、超音波受波器１２からの受波信号を受波部１４で増幅、検波を行う。信号処理部１５において、受波部１４からの信号に応じて異常を検出し、異常を検出した時に出力部１６から警報信号を出力する。 In the wave transmission unit 13, a signal for transmitting ultrasonic waves is generated from the ultrasonic wave transmitter 11, and the ultrasonic waves reflected by the intruder are received by the ultrasonic wave receiver 12, and the ultrasonic wave receiver 12 receives the ultrasonic waves. The received signal from 12 is amplified and detected by the receiving unit 14. The signal processing unit 15 detects an abnormality according to the signal from the receiving unit 14, and outputs an alarm signal from the output unit 16 when the abnormality is detected.

図１は本発明の超音波式検知装置の実施形態の警戒状態を示した図である。
超音波式検知装置１は、複数の超音波センサー１０が柔軟性のある材料２０で長手方向に一定間隔で連結された構成となっている。また、各超音波センサー１０は上部が検知エリアＡを構成するように配置されている。各超音波センサー１０の間隔は、侵入者が超音波センサー１０と超音波センサー１０の間のどこを通っても検知エリアＡを通ることになる間隔とすることが望ましい。 FIG. 1 is a diagram showing a warning state according to an embodiment of the ultrasonic detection device of the present invention.
The ultrasonic detection device 1 has a configuration in which a plurality of ultrasonic sensors 10 are connected by a flexible material 20 at regular intervals in the longitudinal direction. Further, each ultrasonic sensor 10 is arranged so that the upper portion thereof constitutes the detection area A. It is desirable that the distance between the ultrasonic sensors 10 is such that the intruder passes through the detection area A no matter where it passes between the ultrasonic sensor 10 and the ultrasonic sensor 10.

この構成により、超音波式検知装置１は、地面や床に置くだけで警戒状態となり、赤外線式検知装置とは異なり、光軸調整が不要であり、設置時間の短縮につながる。また、地面から検知エリアができているため、侵入者が匍匐前進をしても失報になることはない。 With this configuration, the ultrasonic detection device 1 is in a warning state just by placing it on the ground or the floor, and unlike the infrared detection device, the optical axis adjustment is unnecessary, which leads to a reduction in installation time. In addition, since the detection area is created from the ground, even if an intruder moves forward, it will not be a false report.

図２は、本発明の超音波式検知装置の実施形態の第１の保管状態を示した図である。柔軟性のある材料２０を使用しているため、不使用時はロール状に巻いて保管が可能である。ロール状で保管できるため可搬性に優れている。また、ロール状から広げるだけで警戒状態にできるため、迅速に設置、撤収を行うことができる。 FIG. 2 is a diagram showing a first storage state of the embodiment of the ultrasonic detection device of the present invention. Since the flexible material 20 is used, it can be rolled up and stored when not in use. It has excellent portability because it can be stored in rolls. In addition, since it can be put into a warning state just by unfolding it from the roll shape, it can be quickly installed and withdrawn.

また、上述の実施形態では、送波器と受波器とを個別としたが、ひとつで送波器と受波器を兼用できる素子を使用してもよい。また、図１では検知エリアＡを超音波式検知装置の真上方向に存在させているが、斜め方向に角度を付けて存在させてもよい。また、図２では円状に巻いているが、四角など他の形状で巻いてもよい。また、上述の実施形態では、超音波センサーを柔軟性のある材料で連結を行っていたが、柔軟性のない材料としてもよく、その場合は、図４のように超音波検知装置を単一または複数の超音波センサーごとに折れる構造とし、多角形の形状で巻いて保管してもよい。 Further, in the above-described embodiment, the transmitter and the receiver are separated, but an element that can be used as both the transmitter and the receiver may be used. Further, although the detection area A is present in the direction directly above the ultrasonic detection device in FIG. 1, it may be present at an angle in the oblique direction. Further, although it is wound in a circular shape in FIG. 2, it may be wound in another shape such as a square. Further, in the above-described embodiment, the ultrasonic sensor is connected with a flexible material, but it may be a flexible material. In that case, a single ultrasonic detection device is used as shown in FIG. Alternatively, the structure may be such that each of a plurality of ultrasonic sensors can be folded, and the ultrasonic sensors may be rolled up and stored in a polygonal shape.

以上、本発明の実施形態を説明したが、上述の実施形態は例として提示したものであり、発明の範囲は、これに限定するものではなく、その他の様々な形態で実施されることが可能であり、特許請求の範囲に記載された発明の範囲とその均等の範囲に含まれるものである。 Although the embodiment of the present invention has been described above, the above-described embodiment is presented as an example, and the scope of the invention is not limited to this, and can be implemented in various other embodiments.
