An infrared detection sensor (4) installed in the rear part of the lens (3) in the main body (1) to detect whether an intruder is present as an electrical signal through a change in heat by infrared rays;

When a predetermined output signal is generated from the infrared sensor 4 while the power switch 12 is "on", the output voltage of the battery 8 or the rectifier 9 is applied to the lamp 6 and the alarm 7. A control unit 5 for supplying a predetermined time;

It is installed on the insertion hole 1b of the main body 1 through the cylindrical bracket 15 provided with the elastic locking piece 151, so that the voltage from the controller 5 is reduced because an unspecified person enters from the outside. A lamp 6 that lights up during that time to illuminate the intruder when supplied;

Installed on the inner side of the other side of the main body 1 because the unspecified person intrudes from the outside, when a voltage is supplied from the control unit 5, an alarm sound is generated during that time, causing the intruder to escape and at the same time to the intruder. An alarm 7 indicating that there is;

A battery (8) installed inside the main body (1) so that each part can be operated in a place where external power cannot be supplied;

A rectifier 9 for rectifying commercial power so that each part can be operated even when there is no battery 8;

It has a rectangular plate shape and nail hook groove 101 is formed at one side thereof and the connecting rod 14 of the main body 1 can be laid in the left and right direction with the circular pivoting groove 103 so as to rotate freely 360 degrees. A mounting table 10 having a configuration in which a hemispherical coupler 102 having a cutout groove 104 formed thereinto is formed to protrude and being hung on a wall or placed on a floor to support the main body 1;

The main body having a hemispherical shape and fixedly installed at an end of the connecting rod 14 of the main body 1 through a screw 16 in a state of being placed inside the coupling hole 102 of the mounting table 10 ( It is characterized by consisting of an angle retainer (11) for maintaining the angle between 1) and the mounting table (10).

In this case, the control unit 5 includes an amplifier for amplifying the signal output from the infrared sensor 4 and a filter for passing only infrared light, and at the same time, after the intruder is detected, the infrared sensor 4 The local circuit or timer is provided so that the driving of the lamp 6 and the alarm 7 lasts more than a predetermined time (for example, 10 seconds) even if the sensing area of the sensor is removed.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, since the device of the present invention adopts only a human body sensing method without adopting a camera and a human body sensing method, it may be made very small compared to a conventional camera method when injection molding the main body 1.

That is, the inside and outside of the main body (1) for connecting the infrared sensor 4 and the control unit 5, the main printed circuit board, the battery (8), the lamp (6), the power switch 12 and the rectifier (9) Since only (13) needs to be installed, the size should be injection molded within about 10-12cm in width and within about 5cm in length and height.

Therefore, since the size is very small, it is easy to carry and move, and can be easily installed and used in any place where surveillance is neglected, including a weak area inside the building.

At this time, the front of the main body (1) is placed in the upper and lower settling hole (1a) for installing the detection direction setting aperture (2) rotatably, and the insertion hole (1b) for detachably installing the lamp (6) Also, on the rear side, an access hole 1c is formed so that the battery 8 can be replaced, and the lid 1d is detachably installed on the access hole 1c.

In addition, an upper end of the main body 1 is provided with a jack 13 for selectively coupling the power switch 12 and the plug 91 of the rectifier 9 which is an external power source, and on one side, a mounting table 10 is provided. Is coupled to form a protruding connecting rod 14 to allow the body 1 to be moved from the mounting table 10 at a desired angle.

In addition, the mounting base 10 supporting the main body 1 at a predetermined angle may be injection molded to have a rectangular plate shape, and a nail hook groove 101 is formed at one side thereof, and the main body 1 at the other side thereof. A circular rotating groove 103 is formed so that the connecting rod 14 can be freely rotated 360 degrees, and at the same time, a hemispherical coupling hole 102 formed with a notch groove 104 is formed at the left and right sides of the rotating groove 103. By doing so, the end of the connecting rod 14 of the main body 1 is capable of 360-degree movement in the hemispherical coupling sphere 102 and at the same time may be divided to the left and right.

Of course, the end of the connecting rod 14 has a hemispherical shape and is mutually coupled with the angle retainer 11 coupled through the screw 16 in a state seated in the coupling hole 102 of the mounting table 10. In addition, even if the operator releases his or her hand after rotating the main body 1 in a desired direction, the main body 1 is not detached from the mounting table 10, as well as the angle holder 11 and the mounting table ( The angle between the main body 1 and the mounting table 10 is maintained by the operator by the frictional force generated in the inner surface of the engaging hole 102 of 10).

On the other hand, the sensing direction setting aperture (2) installed on the settling hole (1a) of the main body 1 cuts a part thereof, so that the operator rotates the sensing direction setting aperture (2) appropriately so that the cutout portion Just by being in the direction you want to monitor, you can easily capture the infrared and heat generated from the body of the intruder.

Of course, the detection direction setting aperture (2) is installed on the settling hole (1a) of the main body (1) through a plurality of hook-type locking projection 21 in a state that can be attached and detached, the operator can freely change the direction I can regulate it.

That is, after the operator installs the main body 1 at a predetermined place through the mounting table 10, the operator grasps the main body 1 and rotates it properly, as shown in FIGS. 4 and 5. After properly adjusting the angle between the main body 1 and the main body 1, as shown in FIG. 2, when the sensing direction setting aperture 2 installed in the front part of the main body 1 is properly rotated, the infrared sensing angle can be set to a desired angle. .

At this time, since the lens 3 is fixedly installed on the inner side of the sensing direction setting aperture 2, infrared rays generated from the human body may be collected by the infrared sensor 4.

In addition, since the infrared sensor 4 is installed at the rear portion of the lens 3 in the main body 1, whether the intruder is present through the change of heat by infrared rays is detected by the infrared sensor 4. The electric signal can be detected and output to the control unit 5 accurately.

On the other hand, the device of the present invention is designed to receive the power supply voltage from any one of the output voltage of the battery (8) or rectifier (9), so that it is difficult to supply the power supply voltage from the outside (for example, outdoor) When installing the devised device, the built-in battery (8) is installed, and when installed in a place where commercial power is supplied, the rectifier (9) is designed to compensate for the disadvantage that the operation stops when the battery is consumed. It can be installed while connected to.

Of course, when monitoring a predetermined area through the device of the present invention, the power switch 12 must be "on" so that the controller 5 responds to the output signal of the infrared sensor 4 in the standby state of each component. It is necessary to be able to control the driving (ie driving of the lamp 6 and the alarm 7).

Therefore, the control unit 5 is a battery 8 to the lamp 6 and the alarm 7 when a predetermined output signal is generated from the infrared sensor 4 in the state that the power switch 12 is "on". Alternatively, the output voltage of the rectifier 9 is supplied so that the lamp 6 installed in the front part of the main body 1 is turned on and the alarm sound is generated in the alarm 7 installed in the inner part of the main body 1.

At this time, the control unit 5 may stop the lamp 6 and the alarm 7 for a predetermined time (for example, 10 seconds, even when the intruder is surprised and then exits the detection area of the infrared sensor 4 after the intruder is detected once). ) So that the observer can check the intruder's access and take appropriate action.

Of course, if the lamp 6 installed on the front part of the main body 1 is turned on as described above, and an alarm sound is generated therein, the intruder who is not aware that the device of the present invention is installed may be surprised and may run away, thus preventing theft. In addition, even if the watcher is located at a relatively short distance from the place of intrusion, it is easy to recognize the intrusion and take corrective action.

Unlike the existing security management system, the device of the present invention is mobile and very easy to operate. Therefore, anyone can easily install it anywhere at a low price and secure the monitoring system. It is.

As described above, according to the present invention, any place including a weak area inside a building can be easily installed and used, and anyone can easily adjust the monitoring angle and direction, so that the adjustable Very good, it is a very useful design, such as to prevent theft in advance by simply installing in any place that is not supplied with external power.
