Description
【０００２】
【従来の技術】
所定の空間内を移動する人間を検出する移動物体検出装置として、物体から放射される赤外線を検出する受動型赤外線検出装置が多用されている。この装置は、一つの焦電型赤外線検出素子に、凹面鏡やフレネルレンズ等の光学系により複数の方向からの赤外線エネルギーを集束し、その焦電型赤外線検出素子から得られる検出信号をもとに、移動物体の存在の有無を判定するものである。
従来より、広い範囲を一台の装置によりカバーするために、複数の焦電型赤外線検出素子、光学系及び信号処理系統を備えたものも実用化されている。焦電型赤外線検出素子と光学系及び信号処理系統を一つの検出ユニットととらえたとき、そのような検出ユニットを複数個内蔵した移動物体検出装置は存在していたが、それらの検出ユニットがカバーする検知範囲は、装置全体の検知範囲を拡大するという目的から、相互に重複しない形態を基本としており、それぞれの検出ユニットから得られる検出信号が所定の検知レベルを超えるかどうかを個々に判定して、どれかひとつでも所定の検知レベルを超えた検出ユニットがあれば、ただちに移動物体有りという検知信号を出力するよう構成されていた。

[Conventional technology]
As a moving object detection device that detects a human moving in a predetermined space, a passive infrared detection device that detects infrared rays emitted from an object is often used. The apparatus in one of the pyroelectric infrared detector element, focuses the infrared energy from a plurality of directions by the optical system such as a concave mirror or a full-les Nerurenzu, based on the detection signal obtained from the pyroelectric infrared detection element In addition, it determines the presence or absence of a moving object.
Conventionally, in order to cover a wide range with one device, those equipped with a plurality of pyroelectric infrared detection elements, an optical system and a signal processing system have also been put into practical use. When the pyroelectric infrared detection element, the optical system, and the signal processing system were regarded as one detection unit, there were moving object detection devices incorporating multiple such detection units, but these detection units covered them. The detection range to be detected is basically a form that does not overlap with each other for the purpose of expanding the detection range of the entire device, and it is individually determined whether or not the detection signal obtained from each detection unit exceeds a predetermined detection level. Therefore, if any one of the detection units exceeds a predetermined detection level, it is configured to immediately output a detection signal indicating that there is a moving object.
