本考案は物体が放射する赤外線の量を検出する
素子を用いた受動型侵入者検知装置に関する。[Detailed Description of the Invention] The present invention relates to a passive intruder detection device using an element that detects the amount of infrared radiation emitted by an object.

力と時間を費やさなければならなかつた。 This type of device, so-called passive type, detects infrared rays emitted by an object and detects the presence or absence of an intruder based on the difference in the amount of infrared rays emitted, but the infrared rays used for this are invisible, so When installing a device, it is not possible to visually confirm in which direction the warning area - the optical axis of the detection element - is oriented, and in order to know the true warning area, it is necessary to actually observe an object with a temperature different from the background. It would be a waste of time to search for the optimal warning area. Furthermore, in cases where the optical system uses a multi-parabolic curved surface or the like and the detection element has multiple optical axes, this must be done for each optical axis, requiring a great deal of effort and time to position the device. It was impossible.

A plurality of main lenses L1, L2...Ln are arranged in parallel so that the focal point F of each main lens Ln coincides with the focal point F. In the passive intruder detection device 1 provided with the infrared detection element P, each of the above main lenses
Sub-lenses l 1 , l 2 , ...l o close to Ln, respectively
are arranged in parallel so that the focal point f coincides with the focal point F of the main lens Ln, and the plane including the optical axis XnYn of the main lens Ln and the optical axis xnyn of the sub-lens is a vertical plane. Passive intruder detection characterized in that a light emitting source is provided at a position on the side of the sub-lens L o that is separated from the detection element by the distance between the optical center of the main lens L n and the optical center of the sub-lens L o . Related to equipment.

This is a longitudinal cross-sectional view of the main part taken along a plane including XnYn and xnyn . An infrared detection element P is arranged at a position of parts F and f. Therefore, this detection element P is the main lens Ln
Detect infrared radiation from an object on the objective side on the optical axis XnYn of the lens and the optical axis xnyn of the sublens l o . Light emitting source A is located at a distance b from the optical axis xnyn of the sub-lens l o , but since the light passing through the optical center of the lens travels straight, the light that comes out from the light emitting source A and passes through the sub-lens l o is projected almost parallel to the same direction as the optical axis XnYn of the main lens Ln, and by checking this projection direction, the warning direction of the infrared detection element P passing through the main lens Ln from the detection device 1 side can be known. I can do it.

However, as above, the light passing through the optical center of the lens travels straight, so the infrared detection element P also detects the infrared radiation emitted from the object on the objective side of the sublens L o , and detects the infrared radiation from the light source A. The light is accurately projected in parallel in the same direction as the optical axis of the main lens Ln.

The device can know the warning area that the element is staring at,
It has the feature that a desired warning area can be confirmed at the time of installation of the device without performing an object movement test on the objective side of each lens.
