In the present invention, an area sensed by the sensor device (10) is divided into a plurality of subzones, and it is displayed through the control room application program (30) whether the subzone in which the object is detected is intruded, And does not determine the presence of an object even if an object is detected in one or more subzones specified among the plurality of subzones according to the setting.

In general, an intrusion detection system is a technology that detects whether an object intruding from the outside exists even though it should not enter a specific space according to time or authority.

Such an intrusion detection system basically includes sensor means for detecting an object, camera means, and monitoring means for monitoring.

The technology described above is an intrusion detection radar installed outside the security area; And a plurality of RF reflectors respectively installed outside the guard area and reflecting the radio signal in a predetermined direction so that a radio wave signal radiated from the radar travels along an outer portion of the guard area.

As a result, the number of installed radar detectors can be minimized and the non-detection area can be reduced by reflecting the radio signal radiated from the intrusion detection radar to extend the detection distance and the area.

According to claim 6 of the present invention, "an intrusion detecting radar installed outside the security area is installed on the outside of the security area, and a radio wave signal radiated from the radar is transmitted along the outer area of the security area A plurality of first RF (Radio Frequency) reflectors for reflecting a radio wave signal in a predetermined direction, and a plurality of first RF (Radio Frequency) reflectors provided on the propagation path of the radio wave signal, And a second RF reflector that reflects the radio wave signal so as to be propagated toward a specific region ". However, since the above-described technology can expand the sensing region, There is a problem that the division detection can not be performed.

The above-described problem is not only the above-described technology but also a conventional system for detecting an intruder. Since it is intended to detect a predetermined detection area at a time, accuracy is degraded and partial individual detection is impossible.

Therefore, it is possible to divide a predetermined sensing area by a certain standard, and sensitivity can be adjusted for sensing by each divided area so that individual sensing is possible, and in some situations, It is necessary to develop the technology of the intrusion detection system which can not judge the intrusion even if the object is detected.

The present invention relates to a sensor device (10) capable of detecting whether or not an intruder is intruding, more specifically, a sensor device (10) for transmitting a microwave and receiving a microwave reflected on an object after being transmitted to grasp the presence or absence of an object; A camera device (20) for capturing an image when the presence of an object is determined by the sensor device (10) and turning on the light; And a control room application program (30) capable of communicating with the sensor device (10) and the camera device (20) to manage and remotely control them.

The present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a schematic configuration of an intrusion detection system according to the present invention.

Referring to FIG. 1 of the accompanying drawings, the intrusion detection system according to the present invention may mainly include a sensor device 10, a camera device 20, and a control room application program 30.

The sensor device 10 is installed in a place for intrusion detection, and detects the presence of an object. The sensor device 10 can be installed in a boundary fence according to an embodiment of the present invention.

Accordingly, an object approaching the fence can be detected, and such a sensor device 10 will be described with reference to FIGS. 2 and 3. FIG.

FIG. 2 is an exploded view of the configuration of a sensor device in an intrusion detection system according to the present invention, and FIG. 3 shows the function of control means in an intrusion detection system according to the present invention.

Prior to the description, the sensor device 10 described later may be made of a material having excellent heat resistance and rheological properties, and it is preferably made of a material which does not cause breakage of internal parts even at minus 45 degrees to 60 degrees .

The sensor device 10 of the present invention according to FIG. 2 of the accompanying drawings may mainly include a body unit 100, a control unit 200, a cover unit 300, and an operation unit 400.

The body means 100 functions to accommodate a control means 200 to be described later, and may be configured to be opened in one direction.

The control means 200 controls the sensor device 10 to perform an intruder detection function. The configuration of the control means 200 may be referred to FIG.

3, the control unit 200 mainly includes a communication unit 210, a sub-zone dividing unit 220, a microwave transmitting unit 230, a microwave receiving unit 240, and a microwave analyzing unit 250 can do.

The communication unit 210 enables the sensor device 10 to communicate with the camera device 20 and / or the control room application program 30, which will be described later, and the communication method can employ RS-485 wireless communication .

The sub-zone dividing unit 220 divides the sensing area into a plurality of sub-zones with respect to a sensing area to be sensed, which is set in a place where the sensor device 10 is installed.

At this time, the reference for dividing the subzone equally divides the length of the sensing region. For example, when the length of the sensing region is 60m and the number of subzones is 12, each subzone may be 5m.

The microwave transmitter 230 radiates a beam-shaped microwave and outputs the microwave to the outside. The microwave transmitter 230 may be implemented as an antenna in which patches are arranged as shown in FIG. 2 of the accompanying drawings.

According to such a patch arrangement method, a microwave beam can be emitted. The patch can radiate a beam according to application of electric power, and is arranged in a rectangular shape on a dielectric substrate having a constant thickness.

Here, the material of the dielectric substrate may be a dielectric such as Tefron, Rexolite, and PTEE (Polytetrafluoroethylene).

A plurality of such patches are arranged in one direction to form one patch array, and a plurality of patches may be connected to one another by feed lines.

The patch array is configured to be symmetrical to form a patch array, and the patch array is composed of a plurality of stages, so that the microwave transmitter 230 according to the present invention can be implemented.

The microwave receiving unit 240 can perform the function of receiving the reflected microwave when the microwave outputted from the microwave transmitting unit 230 is reflected by the object.

At this time, the microwave reflected and received may be different depending on the distance that the object is spaced apart from the sensor device 10. In other words, a method using a Doppler effect is employed. In comparison, when the intruder is located at 10 m from the sensor device 10 and when it is located at 20 m, after the microwave is outputted, The time taken for the microwave receiving unit 240 of the microwave receiver 240 to receive the microwave reflected from the object will be different and the wave of the microwave will be different.

Through this analysis, the sensor device 10 can analyze the distance of the intruder on the basis of the sensor device 10, and can include the microwave analysis part 250 for this purpose.

That is, the position of the sub zone in which the object is sensed is detected through the microwave analysis unit 250, and the sensor device 10 uses the sub zone information and the sensing signal as the information, through the communication unit 210, 30).

Hereinafter, the subdivision of the sub zone by the sensor apparatus 10 will be described with reference to FIG. 5 of the accompanying drawings.

FIG. 5 illustrates a detection area of a sensor device in the intrusion detection system according to the present invention.

FIG. 5 of the accompanying drawings shows an example (a) for detecting an intruder by dividing a plurality of subzones and an example (b) for setting at least one subzone among a plurality of subzones to a green zone.

Here, the names of the subzones and the greenzone are intended to facilitate an easy understanding of the present invention, and the subzone should be interpreted as a divided area of the total sensing area, and the greenzone is a subzone in which an intrusion signal is not generated even if an object is detected. .

5A, the sensing area of the sensing sensor 10 of 60 m in total is equally divided into 12 zones so that each sub zone (ⓛ to ⑫) is 5 m.

Then, the sensor device 10 determines through the microwave analysis unit 250 which sub zone the position where the object is sensed is based on the time from when the microwave is outputted to when it is reflected and received by the object .

5 (a), when the intruder is located in the sub zone corresponding to (4) to (6), the output microwave is reflected and is received by the microwave receiving unit 240. At this time, The distance can be calculated according to the time from output to reception (distance = speed x time, speed of the end is the set output speed of the microwave), so that the sub zone in which the intruder exists can be determined.

On the other hand, in FIG. 5 (b), the green zone is set as a green zone, and the green zone may be set together when the sub zone is set by the sub zone division unit 220.

This division of the subzone can be set remotely through the control room application program 30 to be described later.

When the green zone is set as described above, even if an object exists in the green zone and the microwave reflected from the object is received by the microwave receiver 240, the intrusion signal may not be generated according to the control room application program 30 to be described later. This will be described later.

The cover means 300 serves to engage with the body means 100 in one open direction of the body means 100, thereby closing one open side of the body means 100.

The operating means 400 may be installed on one side of the body means 100 to control the tilting and panning operations of the body means 100.

The operation control of the operation means may be configured to be remotely controlled through the control room application program 30, which will be described later, by constructing a communication configuration, although not shown in the drawings.

This operating means 400 includes a base 410, a base hollow 420, a pivot 430, a panning action 440, a tilting portion 450 and a hinge 460, according to Figure 2 of the accompanying drawings. As shown in FIG.

The base 410 is installed directly on the column or the wall surface so that the sensor device 10 can be installed on a column or a wall surface.

The base 410 may have a base hollow 420 formed on one side thereof, and a pivot shaft 430 may be accommodated therein.

The panning operation unit 440 is inserted into the base hollow 420 and connected to the pivot shaft 430 so that the panning operation unit 440 can be operated leftward or rightward according to the rotation of the pivot shaft 430.

The panning operation unit 440 may be formed in a shape in which one side of the body unit 100 is opened and the grooves 441 may be formed on both sides with respect to the open area.

The tilting operation part 450 is inserted into the open area of the panning operation part 440. The tilting operation part 450 is formed with a second groove (not shown in the figure) passing through one side thereof in one direction And the tilting operation part 450 may be inserted into the open area of the panning operation part 440 such that the second groove corresponds to the position of the groove 441 of the panning operation part 440.

The hinge 460 is installed to penetrate the groove 441 in the order of the one groove 441 and the groove 441 in the other groove so that the tilting operation part 450 can be connected to the panning operation part 440. And the panning operation unit 440 may be a reference axis operated in an upward direction or a downward direction.

One side of the tilting operation part 450 may be directly connected to the sensor device 10.

The camera device 20 is installed to view the direction of the sensing area of the sensor device 10 and may include a camera 21 and a light 22 provided on both sides of the camera 21.

That is, when the control room application program 30 determines that an intruder is present according to the detection signal of the sensor device 10, the camera device 20 receives the detection result and operates in the direction of the sub zone in which the object is sensed, ), The light 22 is operated to enable easy image acquisition, and the intruder can have a sense of crisis.

At this time, the operation of the camera apparatus 20 in the sub zone direction can be manually performed through the control room application program 30 described later, and the position information of the set sub zone (e.g., 'sub zone information' Meaning) can be shared by the camera device 20 and the camera device 20 can be automatically operated to the position of the corresponding sub zone.

The control room application program 30 is installed in a terminal (a computer, a notebook, a smart terminal, etc.) provided in the control room, and the control room application program 30 will be described with reference to FIG. 4 of the accompanying drawings.

4 is a block diagram illustrating the configuration of an application program installed in the control room in the intrusion detection system according to the present invention.

The control room application program 30 according to the present invention shown in Fig. 4 of the accompanying drawings can mainly include a communication unit 31, a remote control unit 32, a setting unit 33 and an interface providing unit 34 .

The communication unit 31 enables the control room application program 30 to communicate with the above-described sensor device 10 and / or the camera device 20. [ At this time, at least one of wired communication and wireless communication may be employed as the communication method employed.

The remote control unit 32 enables the control room application program 30 to remotely control the sensor device 10 and the camera device 20 at the time of control.

At this time, the remote control may be sub zone division, green zone setting, and the like in the case of the sensor device 10, and may be a camera direction change, image pickup on / off, light on / off, and the like in the case of the camera device 20.

The setting unit 33 sets a reference value for outputting an alarm for detecting an intrusion from the sensor device 10 or a reference value for generating an intrusion signal when an object is sensed. Lt; / RTI >

The intrusion determining unit 34 performs a function of determining an intruder based on the sub zone information and the detection signal received from the sensor device 10, and can generate an intrusion signal if it is determined that an intruder exists.

The intruder determining unit 34 may determine the intruder by operating in conjunction with the interface providing unit 36, which will be described with reference to FIG. 6 of the accompanying drawings.

FIG. 6 schematically shows an example of an interface provided by an application program of the intrusion detection system according to the present invention.

First, the interface providing unit 36 may include a mute interface 36a, an alarm interface 36b, an alarm setting interface 36c, an intrusion display interface 36d and an intrusion signal setting interface 36e, Reference is made to Fig. 6 of the accompanying drawings for an example of a screen in which such an interface is provided.

FIG. 6 of the accompanying drawings shows a screen related to an alarm (Alarm) and a screen related to an intrusion signal (Norm).

6, a mute interface 36a for selecting a sound output and a mute is commonly displayed. When a screen (Norm) related to an intrusion signal is viewed, a reference value for generating an intrusion signal at the lower end of the corresponding screen The intrusion signal setting interface 36e may provide a plurality of setting interfaces so as to correspond to a plurality of (12) subzones.

That is, based on the reference value set in the intrusion signal setting interface 36e, the intrusion determining unit 34 determines (a) the position of the sub zone in which the object is detected according to the sub zone information received from the sensor device 10 (b) if the detection signal received from the sensor device 10 exceeds the reference value, it can be determined that an intruder exists.

Referring to FIG. 6 of the accompanying drawings, the intrusion signal setting interface 36e sets each sub zone to a reference value of 50%. In the intrusion display interface 36d at the upper part thereof, The zone exceeds the reference value and an intruder exists.

On the other hand, if there is a sub zone set to the green zone as described above and the corresponding green zone is the sub zone of? And?, The intrusion signal setting interface 36e corresponding to the sub zones of? By setting the reference value to 100%, an intrusion signal can be prevented from being generated even if an object is detected.

At this time, if the detection signal received from the sensor device 10 does not exceed the reference value, it can be determined that an intruder does not exist, but it also means that an object exists in the corresponding sub zone.

In this case, the object is not an intruder, but rather a person other than a small animal such as a bird, a dog, or a cat. However, It does not mean other forms.

For example, it is necessary to be able to detect an intrusion of a car, and even if a person is in a crawl, the form of intrusion may be different. Therefore, the object to be detected must be interpreted as a form other than a predetermined form.

In other words, according to the present invention, the anomaly detection object can be prevented from generating an intrusion signal because it is not determined that the anomaly detection object is an intruder according to the set reference value, and may include the anomaly detection target skin 35 for this purpose.

That is, if the sensor 35 receives the detection signal from the sensor device 10 but is below the preset reference value, the sensor 35 determines that the sensor 35 is abnormal and the intruder 34 does not generate an intrusion signal .

On the other hand, in implementing the anomaly detection target skin 35, other methods may be employed.

For example, by using the point that the shape of the object can be recognized because the object is detected by using the microwave, the anomaly detection target skin 35 includes (a) storage means capable of storing a predetermined anomaly detection form (B) comparing the detected shape with a previously set abnormality detection form to determine whether the detected abnormality is similar to the abnormality detection form, or (Storage means) in advance. If the object exceeds the size, the intrusion determination unit 260 may generate an intrusion signal.

The storage means and / or the comparison means described above may be provided in the control room application program 30 to be described later.

6, an alarm interface 36b and an alarm setting interface 36c are shown. At this time, the alarm setting interface 36c allows setting of alarm threshold values.

Apart from generating an intrusion signal, if the intrusion signal setting interface 36e of a specific sub zone is set to 50% and the alarm setting interface 36c of the sub zone is set to 30%, for example, As the anomaly detection object approaches, an alarm is outputted even if the intrusion signal is not generated, so that it can be known which object has approached.

To this end, the control room application program 30 may include an alarm generation unit 37. The alarm generation unit 37 generates an alarm when the preset reference value is exceeded based on the alarm setting interface 36c And / or outputting an alarm.

When mute is activated through the mute interface 36a described above, it is possible to display only the red color on the screen of the control room application program 30 and not to output the sound, and when the mute is disabled, And the like.

1 to 6 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 6 It is self-evident.
