Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a device for adjusting the angle of a sensor unit in an intrusion monitoring system.

[0002]

[Prior art]

 In an intrusion monitoring system for monitoring the intrusion of a suspicious person into a factory or facility, the infrared sensor or laser sensor unit is housed in a box-shaped casing 21 as shown in FIGS. 9 and 10, and this casing is The optical axis of the sensor unit can be adjusted by rotating around the tilt axis and the horizontal axis.

[0003]

[Problems to be solved by the device]

 However, such a conventional angle adjusting device has a problem that it takes a long time for the adjusting work because the angle adjustment cannot be performed vertically and horizontally. In particular, the sensor had to be repeatedly adjusted in order of top-bottom → left-right → top-bottom to maximize the sensitivity.

Further, the design image of the box-shaped casing is not soft. In particular, a camera often sees people, which is intimidating.

The problem to be solved by the present invention is to make the upper and lower structures soft by eliminating the intimidating image by using a simple structure capable of adjusting vertically and horizontally at the same time.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a sensor unit angle adjusting device of an intrusion monitoring system according to the present invention is a sensor unit in which a light receiving unit or a light projecting unit is formed at one end opening of a spherical casing, and the light receiving unit is built in the casing. , At least one of the two casing mounting plates having an opening having a diameter smaller than the maximum diameter of the spherical casing is mounted on the main body of the apparatus so that it can be moved and fixed in substantially the same direction as the optical axis of the light receiving apparatus. However, the casings are fixed at an arbitrary angle with the inner edges of the openings of the two casing mounting plates sandwiching both sides of the maximum diameter portion of the spherical casing.

[0007]

[Embodiment of device]

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an intrusion monitoring device constituting the intrusion monitoring system of the present invention. As shown in the figure, a spherical casing 3 is vertically arranged inside an acrylic pole 2 fixedly installed on a base 1. There is. The casing 3 is preferably made of aluminum die-casting which is not easily deformed by temperature changes in the outdoors, but is not limited to the material. As shown in FIG. 2, the casing 3 is provided with a lens 4 on the front surface and a lid portion 5 on the rear surface, and is supported by columns 6. A light receiving element 10 for receiving the light condensed by the lens 4 is attached to the lid 5 of the casing 3 together with the control board. As shown in FIG. 3, the pillars 6 are installed with a space left and right, and between the pillars 6, a pillar mounting plate 7 having an opening slightly smaller than the diameter of the casing 3 is fixed to the holder 13 with a fixing screw 14. In front of the column mounting plate 7, the hair-bedding fixing member 8 is attached to the column mounting plate 7 by passing through the holder 13 with a fixing screw 9. Before adjustment, as shown in FIG. 4, the casing 3 is attached by the column mounting plate 7 and the casing fixing plate 8, and after being fixed, it is appropriately pressed by the spring 11 so as not to rotate due to vibration. At the time of adjustment, the finder 12 provided on the casing 3 is aimed at the light emitting part of the other party, and the angle is adjusted while simultaneously moving the casing 3 in the left-right and up-down rotation directions with both hands. FIG. 5 is an exploded perspective view of FIG.

In the embodiment shown in FIG. 4, the light receiving device built in the casing 3 is composed of the lens 4 and the light receiving element 10. However, as shown in FIG. 6, the small camera 15 with the lens 16 is built in the casing 3. In addition, it can be used as an intrusion monitoring device for the application shown in FIG.

The beam configuration for intrusion warning is as shown in FIG. 7. However, in the conventional type shown in FIG. 8A, a gap is created between the sensors and the sensor after receiving the beam leak of the previous sensor. This caused interference, and in the case of the identification beam in particular, the pulses overlapped and malfunctioned. These can be solved by mounting a cover to prevent gaps, but the mounting shape becomes complicated and costly. On the other hand, in this embodiment, as shown in FIG. 8 (b), the support mounting plate 6 can eliminate the gap, which prevents malfunction and eliminates the need for a cover.

[0010]

[Effect of device]

 As described above, the present invention has the following effects.

(1) Since the optical axis can be adjusted vertically and horizontally by simply turning the spherical casing, the adjustment work time can be shortened.

(2) Since the light receiving device is housed in the spherical casing, there is no angular appearance, and it is possible to give a soft image.
