Description

Infrared monitoring device {Ultra-Red Luminating Apparatus}

The present invention relates to an infrared monitoring device, and more particularly, to an infrared monitoring device capable of sending a warning message to an monitored person captured by the infrared monitoring device.

In order to photograph a subject in the absence of a light source such as sunlight, it is necessary to use an artificial light source. If you need to continue shooting a specific area at night, such as a surveillance camera, the use of visible light as an artificial light source allows the monitored person to check the light source in advance, making it hard to expect a surveillance effect. When it is turned on, there are disadvantages such as a lot of power consumption and a limited range of visible light that can be secured by visible light.

In order to solve the problem of using visible light as an artificial light emitting source, a technique using infrared light as an artificial light emitting source has been developed, and a technology using a laser diode (LD) and a light emitting diode (hereinafter, referred to as 'LED') Each technology has relative advantages and disadvantages for other technologies.

In the case of the conventional infrared monitoring device has a problem that the illumination efficiency for the subject is inferior because the divergence angle of the infrared light is fixed, so that the infrared can not be concentrated and irradiated at the position of the subject. In order to solve this problem, technologies such as Korean Patent No. 10-518250 and Korean Patent No. 10-537050 have been developed. Both cases focus the infrared light on the subject by adjusting the irradiation angle of the infrared light source using a lens. It allows you to investigate.

If an observer is found while monitoring using such an infrared monitoring device, it may be necessary to give a warning message to the monitored person.Infrared rays are irradiated to the monitored person or the monitored object and not visible light. Since it does not recognize infrared light, the monitored person cannot confirm that he or she is being monitored by the monitoring device. The most easily remembered method for warning is to use a sound such as a warning sound or a warning message. There is a problem in that a warning message cannot be delivered to a remote monitor because the distance to which the sound is transmitted is limited. In addition, when a warning sound of a cone sound is generated in order to warn a remote monitor, there is a problem such as displeasure of people around the monitoring device causing complaints.

When only one of the pan means 50 and the tilt means 40 is implemented, the pantrate may be a pan plate used solely for the pan means or the tilt means, but as in the present embodiment, the pan means 50 and When the tilt means 40 is used at the same time, one pantrate can be used at the same time as the tilt means and the pan means, and the pan plate in the same configuration but explaining the configuration related to the tilt means 40 is identified by the identification number 51. In the description of the configuration associated with the fan means 50, the pan plate will be described with the identification number 41.

The tilt plate 42 is fixed to the lower portion of the infrared emitting means 20 as a "c" detective plate.

The hinge pin 42 is rotatably coupled to the tilt plate 42 and the pan plate 41 is provided on the pan plate 41, the end portion thereof penetrates the tilt plate 42 It is provided in one state and a pair is provided in the plate of the tilt plate 42 in the up-down direction.

Linear movement in a direction away from the center.

Hereinafter, the principle of moving the infrared divergence center by using the pan means 50 and the tilt means 40 of the above-described infrared monitoring device will be described with reference to FIGS.

3 is a view for explaining the operation principle of the pan means and the tilt means shown in Figure 2, Figures 4a to 4c is a view for explaining the operation of the pan means shown in Figure 2, Figures 5a and 5b Is a view for explaining the operation of the tilt means shown in FIG.

As shown in FIG. 3, the rotation bar 2 rotates along the rotation center indicated by C1, and an end (hereinafter referred to as “second end portion”) opposite to the rotation center has a guide hole 1 provided in the guide bar 3. Along the straight motion.

The guide bar 3 rotates along the point marked C2 on the drawing.

When the rotating bar 2 rotates, the second end of the rotating bar 2 moves along the guide hole 1, and in this process, the guide bar 3 also rotates in the same direction as the rotation direction of the rotating bar 2. Done. At this time, when the rotating bar 2 rotates by β °, the guide bar rotates by 2β °.

This principle is applied to the pan means 50 and the tilt means 40 so as to properly rotate the infrared light emitting means 20 to move the infrared light emitting center.

Hereinafter, the operation of the tilt means 40 will be described.

In the tilt means 40, the configuration corresponding to the guide bar 3 is the fan shaft plate 52 and the fan guide bar 53, and the configuration corresponding to the guide hole 1 is the fan guide hole 54. The configuration corresponding to the rotating bar 2 is the fan bar 56.

4A illustrates a state in which the fan bar 56 and the fan guide bar 53 face the same direction. When the fan motor 55 is rotated in this state, as shown in FIGS. 4B and 4C, when the fan bar 56 is rotated by the fan motor 55, the other end of the fan bar 56 is fan guide hole 54. You will have a linear motion inside. At this time, since the fan guide bar 53 and the fan shaft plate 52 are fixed, the fan plate 56 which is fixed to the fan bar 56 while the fan bar 56 rotates relatively rotates together with the fan motor 55. do. Infrared light emitting means 20 is coupled to the upper portion of the pan plate 51 is to rotate together with the pan plate 51. However, in the case of the mechanism shown in FIG. 3, the rotary bar 2 rotates without movement, and the guide bar 3 is configured to rotate, but the tilt bar 40 of the present embodiment corresponds to the guide bar 3. The fan plate 53 and the fan guide bar 53 are fixed and slightly different in that the center of rotation of the fan bar 56 is configured to move, but the relative rotation is shown in FIGS. 4A to 4C. It is judged that the description of the operation of the tilt means 40 has been sufficiently made by the drawings and the above description.

The operation of the tilt means 40 is also performed by the same operation principle as the operation of the fan means 50 described above. In the tilt means 40, the configuration corresponding to the rotary bar 2 is the tilt bar 46, and the configuration corresponding to the guide bar 3 is the configuration corresponding to the tilt plate 42 and the guide hole 1. Tilt guide hole 44. 5A and 5B are diagrams for explaining the operation, the other end of the tilt bar 46 as the tilt motor 45 is rotated in the process of linear movement in the tilt guide hole 44 The center of rotation of the motor 45 is moved along the circular orbit and thus the tilt plate 42 is made to rotate relative to the hinge pin 43 with respect to the pan plate 41, thereby tilting the plate 42. Infrared divergence center of the infrared radiating means 20 fixed to is moved.

In the case of the fan means 50 and the tilt means 40, the means for transmitting the rotation of the motor, which is relatively simple and light in weight and compact, compared to a complicated mechanism such as a belt or gear train, which is a rotational transmission means of the same type. It is also a structure that has advantages.

Hereinafter, a method of monitoring a specific area at night by using the infrared monitoring device described will be described.

First, by using the pan means 50 and the tilt means 40, the infrared camera 10 is rotated up, down, left and right, and outputs a screen of an area to be monitored. When the infrared camera 10 rotates up, down, left, and right, the control unit generates a signal capable of moving in conjunction with the infrared light emitting means 20 and the infrared camera 10, so that the infrared camera 10 and the infrared light emitting means 20 They rotate in the same direction.

While rotating the infrared camera 10 and outputting a screen for a region to be monitored, if a subject that is determined to be needed to be enlarged and found is found, the subject is enlarged by zooming in while the infrared camera 10 is fixed. do. At this time, when the infrared camera 10 is zoomed in, the viewing angle is narrowed. In response to this, the diverging angle of the infrared emitting means 20 is also narrowed by the control signal of the controller so that the infrared light focused on the subject can be obtained.

At this time, if the subject is a human, the human eye does not recognize infrared rays, so it cannot recognize that they are being monitored. When it is necessary to transmit a warning message, the xenon light 30 illuminates the visible light on the subject. . The irradiation angle of the xenon light 30 is determined in consideration of the irradiation angle of the infrared light emitting means 20, and the control unit performs this operation.

In the above description, the case where the warning light means is xenon light has been described, but it is not necessarily included in the technical idea of the present invention to use the xenon light as the warning light means, and it is possible to illuminate visible light as a warning to the monitor. Any warning lighting means may be used as the means, and such modifications should be regarded as included in the technical spirit of the present invention.

In the above, the case in which the pan means and the tilt means are used has been described, and the configuration thereof has been described in detail. However, the pan means and the tilt means may not be provided when the stationary point is monitored. It should be regarded as being included in the technical idea, and configurations limited to the embodiments described as the pan means and the tilt means should not be included in the technical idea of the present invention, and other various types of pan means and tilt means may be used and such variations. The implementation may be regarded as an implementation included in the technical idea of the present invention.
