Description

【０００１】
【発明の属する技術分野】
本発明は、侵入者検知装置、特にその検出視野に対する妨害物又は妨害行為を監視する接近物体検知器を備えた侵入者検知装置固定用のベースに関するものである。
【０００２】
【従来の技術】
侵入者検知装置の外部異常、特に視野妨害を監視するため、装置本体への物体の接近を効果的に監視する機構が、いくつか発明されている。国際公開公報ＷＯ８８／０３３０１には、監視用視野を横断する方向に赤外線を照射する２つの投光素子と、前記投光素子から発せられた赤外線が、接近した物体で反射して入射したことを検出するための１つの受光素子とを備えたセンサが開示されている。この発明によれば、感度を高くしたり、応答時間を短くしたりすることにより、多くの種類の視野妨害行為を検出することができるが、その反面、感度を高くし過ぎることにより、誤動作が多くなるという問題がある。
【０００３】
【発明が解決しようとする課題】
侵入者検知装置本体に視野妨害行為検出機構を内蔵しているため、侵入者検知機能だけを備えた検知装置よりもコストが増加する。また、侵入者検知機能だけを備えた検知装置をもとに構成した既設のシステムに、後から視野妨害行為検出機構を追加しようとしたときには、検知装置全体を交換しなくてはならず、機器コスト、工事コストともに大きな追加負担を強いられることとなっていた。
【０００４】
【課題を解決するための手段】
本発明では、視野妨害行為検出機構を侵入者検知装置本体に内蔵するのではなく、侵入者検知装置固定用のベース側に内蔵させ、ベースの交換のみで、この視野妨害行為検出機構の追加及び削除を可能とした。
【０００５】
【発明の実施の形態】
図１は、本発明の接近物体検知器内蔵ベースの断面図であり、天井３０に固定された状態を示している。接近物体検知器内蔵ベース１０の中央部には、外部の電源装置と結ばれる電源用配線と、外部の制御装置と結ばれる信号用配線（ともに図示省略）を導入する開口部１７を備えている。Ｍは接近物体検知器であり、Ｃ１とＣ２は、侵入者検知装置２０との間で、電源と信号の受け渡しをおこなうコネクタである。侵入者検知装置２０を接近物体検知器内蔵ベース１０に取り付けると、自動的にこのコネクタＣ１とＣ２が、結合するように構成されている。Ｓは、接近物体検知器Ｍの検知エリアである。検知エリアＳは、侵入者検知装置２０の検出視野に対する妨害物又は妨害行為を監視するのに最適な位置に設定されている。
【０００６】
図２は、本発明の接近物体検知器内蔵ベースの底面図である。１１は、外部の電源装置と結ばれる電源用配線を接続する第１の端子台、１２は、外部の制御装置と結ばれる信号用配線を接続する第２の端子台である。１８は、第１の端子台１１、第２の端子台１２、コネクタＣ１を実装したプリント基板である。プリント基板１８上の印刷配線により、端子台とコネクタとの間が接続され、接近物体検知器Ｍと結ばれる配線は、このプリント基板上の印刷配線に接続される。
【０００７】
図３は、接近物体検知器内蔵ベースのブロック図であり、本発明の第１の実施形態を示すものである。第１の端子台１１の１番端子は、コネクタＣ１の１番ターミナルに、第１の端子台１１の２番端子は、コネクタＣ１の２番ターミナルに、それぞれ接続されている。また、第１の端子台１１の１番端子と、第１の端子台１１の２番端子は、接近物体検知器Ｍのモジュール用電源部１３の入力部にも接続されている。第２の端子台の３番端子は、接近物体検知器の出力部の一方に接続され、他方の出力部は、コネクタＣ１の３番ターミナルに接続されている。第２の端子台の４番端子は、コネクタＣ１の４番ターミナルに接続されている。
【０００８】
以上の構成のベースに接続されるのが侵入者検知装置２０であり、コネクタＣ２、センサー用電源部２１、侵入者検出部２２、侵入者検出信号出力部２３とで構成されている。コネクタＣ２の１番ピンと、コネクタＣ２の２番ピンは、センサー用電源部２１と接続され、コネクタＣ２の３番ピンと、コネクタＣ２の４番ピンは、侵入者検出信号出力部２３と接続されている。侵入者検出部２２が侵入者を検出すると、侵入者検出信号出力部２３内の、スイッチ部が開放され、無電圧の接点信号としてコネクタＣ２を通じて出力される。
【０００９】
接近物体検知器内蔵ベース１０の接近物体検知器Ｍは、第１の端子台に電源が供給されると直ちに待機状態に入る。接近物体検知器Ｍ内の物体検出部１４が、接近する物体を検出すると、物体検知信号出力部１５内のスイッチ部が開放される。物体検知信号出力部１５の出力部と、侵入者検知装置２０の侵入者検出信号出力部２３の出力部は、直列接続され、第２の端子台１２の３番端子と４番端を通じて、外部の制御装置と接続される。侵入者検知装置が侵入者を検出したときも、接近物体検知器が接近する物体を検出したときも、ともに第２の端子台から警報信号として出力される。
【００１０】
図４は、本発明の第２の実施形態を示すブロック図である。接近物体検知器Ｍのモジュール用電源部１３の入力部に接続される電源は、コネクタＣ１の５番ターミナル、６番ターミナルから入力される。第１の端子台の１番端子、２番端子は、コネクタＣ１の１番ターミナル、２番ターミナルに、それぞれ接続され、第１の端子台に入力された電源は、コネクタＣ１、Ｃ２を経て侵入者検知装置へ送られる。そして、侵入者検知装置のコネクタＣ２の５番ピン、６番ピンを経て、コネクタＣ１の５番ターミナル、６番ターミナルへ戻されるようになっている。その他の構成は、第１の実施形態と同じである。この構成によれば、接近物体検知器内蔵ベース１０の接近物体検知器Ｍは、第１の端子台に電源が供給されると直ちに待機状態に入るのではなく、侵入者検知装置２０が、接近物体検知器内蔵ベース１０に固定されてから、待機状態となる。
【００１１】
図５は、本発明の第３の実施形態を示すブロック図である。接近物体検知器Ｍはモジュール用電源部を備えておらず、この入力部に接続される電源は、侵入者検知装置内で安定化された電源を用いるようにしている。第１の端子台の１番端子２番端子は、コネクタＣ１の１番ターミナル、２番ターミナルに、それぞれ接続され、第１の端子台に供給される電源は、コネクタＣ１、Ｃ２を経て侵入者検知装置へ送られる。そして、侵入者検知装置のセンサー用電源部で安定化され、コネクタＣ２の５番ピン、６番ピンを経て、コネクタＣ１の５番ターミナル、６番ターミナルへ戻されるようにした。このようにして供給される電源により、物体検出部１４が直接駆動され、接近する物体を検出すると、物体検知信号出力部１６から検知信号が出力される。
【００１２】
物体検知信号出力部１６は、コネクタＣ１の７番ターミナル、８番ターミナルに、それぞれ接続され、コネクタＣ１、Ｃ２を経て侵入者検知装置２０の信号出力部２４へ送られる。信号出力部２４では、侵入者検出部２２から送られてくる信号と、物体検知信号出力部１６から送られてくる信号を基に、警報信号を出力する。この警報信号は、コネクタＣ２の３番ピン、４番ピン、コネクタＣ１の３番ターミナル、４番ターミナルを経て、接近物体検知器内蔵ベース１０の第２の端子台の、３番端子、４番端子から外部の制御装置へ送られる。この実施形態における警報信号は、無電圧の接点信号ではなく、その侵入者検知装置に割り当てられた固有のアドレス、警報の種類などの情報を含んだデータ信号である。この構成によれば、接近物体検知器Ｍに、電源を安定化するモジュール用電源部を備える必要がなくなり、接近物体検知器内蔵ベース１０のコストを下げることができる。
【００１３】
視野妨害行為検出機構を備えていない普通の侵入者検知装置のベース構成が、コネクタＣ１の１番、２番ターミナルと、第１の端子台１１の１番、２番端子とが直接接続され、コネクタＣ１の３番、４番ターミナルと、第２の端子台１２の３番、４番端子とが直接接続される構成となっている場合には、この普通の侵入者検知装置のベースの代わりに、本発明の接近物体検知器内蔵ベース１０を、取り付けると、特別な結線等何の追加作業もおこなうことなく、視野妨害行為検出機構を備えた侵入者検知装置となる。
【００１４】
発明の実施の形態の中で説明した接近物体検知器Ｍの検知エリアＳは、侵入者検出部２２の検出エリアＶを横切る形で設定されているが、検出エリアＶが通過する侵入者検知装置のカバー部分への妨害行為を効果的に監視する形態であればよく、この形態に限定されるものではない。また、侵入者検知装置は、監視フィールド内の物体が放射する赤外線エネルギーを検出する受動型赤外線センサだけに限定されず、他の受動型の検知装置や監視用ビデオカメラであってもよい。監視用ビデオカメラである場合には、侵入者検出部２２は、ＣＣＤ等で構成される撮像素子ということになり、信号出力部２４から出力される警報信号は、映像信号、その侵入者検知装置に割り当てられた固有のアドレス、警報の種類などの情報を含んだデータ信号ということになる。
【００１５】
接近物体検知器Ｍの検出方式は、赤外線を照射する投光素子と、この投光素子から発せられた赤外線が、接近した物体で反射して入射したことを検出するための受光素子とを備えたセンサによるものに限定されるものではなく、受動型赤外線センサによるもの、超音波のドップラー方式によるもの等他の方式によるものでもよい。発明の実施の形態の説明の中では、ベースと侵入者検知装置本体との間で、電源と信号の受け渡しをおこなう接続機構として、一体型のコネクタを用いているが、侵入者検知装置２０を接近物体検知器内蔵ベース１０に取り付けたときに結合するように構成されている接続機構であれば、どのようなものでもよい。
【００１６】
【発明の効果】
本発明では、視野妨害行為検出機構を侵入者検知装置本体に内蔵するのではなく、侵入者検知装置固定用のベース側に内蔵させ、視野妨害行為検出機構を備えていない侵入者検知装置のベースとの互換性を持たせたので、ベースの交換のみで、この視野妨害行為検出機構の追加及び削除が可能となった。侵入者検知装置本体のコストはそのままで、視野妨害行為検出機構を必要とする場所に限定して、この機構の取捨選択が可能となり、システム全体のコストが低減される。接近物体検知器内蔵ベースとして、設置場所に応じた様々な検知方式のものを開発することができ、侵入者検知装置に内蔵した形で開発するよりも、開発コストが少なくて済む。

BACKGROUND OF THE INVENTION
The present invention relates to an intruder detection device, and more particularly to a base for fixing an intruder detection device having an approaching object detector for monitoring an obstacle or an obstruction to the detection visual field.
[0002]
[Prior art]
Several mechanisms have been invented to effectively monitor the approach of an object to the device body in order to monitor external anomalies of the intruder detection device, particularly visual field disturbances. In International Publication No. WO88 / 03301, two light projecting elements that irradiate infrared rays in a direction transverse to the visual field for monitoring, and infrared rays emitted from the light projecting elements are reflected by an approaching object and incident. A sensor including one light receiving element for detection is disclosed. According to the present invention, it is possible to detect many types of visual field disturbance acts by increasing the sensitivity or shortening the response time, but on the other hand, by making the sensitivity too high, malfunctions may occur. There is a problem of increasing.
[0003]
[Problems to be solved by the invention]
Since the intruder detection apparatus main body incorporates the visual field disturbance act detection mechanism, the cost increases compared to a detection apparatus having only an intruder detection function. In addition, when an attempt is made to add a visual field disturbance detection mechanism to an existing system that is based on a detection device having only an intruder detection function, the entire detection device must be replaced. Both the cost and the construction cost were forced to add a large additional burden.
[0004]
[Means for Solving the Problems]
In the present invention, the visual field disturbance act detection mechanism is not built in the intruder detection device main body, but is incorporated in the base side for fixing the intruder detection device, and only by replacing the base, Deletion is possible.
[0005]

The first terminal of the first terminal block 11 and the second terminal of the first terminal block 11 are also connected to the input section of the module power supply section 13 of the approaching object detector M. The third terminal of the second terminal block is connected to one of the output parts of the approaching object detector, and the other output part is connected to the third terminal of the connector C1. The fourth terminal of the second terminal block is connected to the fourth terminal of the connector C1.
[0008]
The intruder detection device 20 is connected to the base configured as described above, and includes a connector C2, a sensor power supply unit 21, an intruder detection unit 22, and an intruder detection signal output unit 23. The first pin of the connector C2 and the second pin of the connector C2 are connected to the sensor power supply unit 21.

When the intruder detection unit 22 detects an intruder, the switch unit in the intruder detection signal output unit 23 is opened and output as a no-voltage contact signal through the connector C2.
[0009]
The approaching object detector M of the approaching object detector built-in base 10 immediately enters a standby state when power is supplied to the first terminal block. When the object detection unit 14 in the approaching object detector M detects an approaching object, the switch unit in the object detection signal output unit 15 is opened. The output unit of the object detection signal output unit 15 and the output unit of the intruder detection signal output unit 23 of the intruder detection device 20 are connected in series, and are connected to the outside through the third terminal and the fourth end of the second terminal block 12. Connected to the control device. Both when the intruder detection device detects an intruder and when the approaching object detector detects an approaching object, the alarm signal is output from the second terminal block.
[0010]
FIG. 4 is a block diagram showing a second embodiment of the present invention. The power source connected to the input unit of the module power source unit 13 of the approaching object detector M is input from the 5th terminal and 6th terminal of the connector C1.

Sent to the person detection device. And it is returned to the 5th terminal of the connector C1, and the 6th terminal through the 5th pin and the 6th pin of the connector C2 of the intruder detection device. Other configurations are the same as those of the first embodiment. According to this configuration, the approaching object detector M of the approaching object detector built-in base 10 does not immediately enter a standby state when power is supplied to the first terminal block, but the intruder detection device 20 After being fixed to the object detector built-in base 10, it enters a standby state.
[0011]
FIG. 5 is a block diagram showing a third embodiment of the present invention. The approaching object detector M does not include a module power supply unit, and the power source connected to the input unit uses a power source stabilized in the intruder detection device.

Sent to the detector. And it stabilized by the power supply part for sensors of an intruder detection apparatus, and it returned to the 5th terminal of the connector C1, and the 6th terminal via the 5th pin of the connector C2. When the object detection unit 14 is directly driven by the power supplied in this way and detects an approaching object, a detection signal is output from the object detection signal output unit 16.

According to this configuration, the approaching object detector M does not need to include a module power supply unit that stabilizes the power supply, and the cost of the approaching object detector built-in base 10 can be reduced.
[0013]
The base configuration of an ordinary intruder detection device that does not include a visual field disturbance detection mechanism is such that the first and second terminals of the connector C1 are directly connected to the first and second terminals of the first terminal block 11, When the 3rd and 4th terminals of the connector C1 and the 3rd and 4th terminals of the second terminal block 12 are directly connected, instead of the base of this ordinary intruder detection device If the base 10 with a built-in approaching object detector according to the present invention is attached, an intruder detection apparatus having a visual field disturbance act detection mechanism is obtained without performing any additional work such as special connection.
[0014]

This is a data signal including information such as the unique address assigned to the alarm and the type of alarm.
[0015]
The detection method of the approaching object detector M includes a light projecting element that emits infrared light, and a light receiving element for detecting that the infrared light emitted from the light projecting element is reflected by an approaching object. However, the present invention is not limited to those using a sensor, and other methods such as a passive infrared sensor, an ultrasonic Doppler method, and the like may be used. In the description of the embodiment of the present invention, an integrated connector is used as a connection mechanism for transferring power and signals between the base and the intruder detection device main body.

[0016]
【The invention's effect】
In the present invention, the visual field obstruction detection mechanism is not built in the intruder detection device main body, but is incorporated in the base for fixing the intruder detection device, and the base of the intruder detection device not equipped with the visual disturbance operation detection mechanism. Because of this compatibility, it has become possible to add or delete this visual field disturbance detection mechanism simply by replacing the base. The cost of the intruder detection device main body is kept as it is, and it is possible to select this mechanism only in a place where the visual field disturbance act detection mechanism is required, thereby reducing the cost of the entire system. As the approaching object detector built-in base, various detection methods according to the installation location can be developed, and the development cost can be reduced compared with the case where the approaching object detector is built in the intruder detection device.
