In this case, the distance detecting unit 20 and the security signal receiving unit 30 may be selectively included.

The hot wire detector 10 detects infrared rays emitted from a monitoring target including a person and outputs a corresponding electrical signal.

The distance detecting unit 20 outputs an infrared ray and outputs a signal according to whether the output infrared ray is received. The distance sensing unit 20 is formed of an active infrared distance sensor, and may measure the presence or absence of a predetermined object and a distance of the object according to a signal output from the distance sensing unit 20. For example, the distance sensor 20 outputs an infrared ray and then outputs a signal indicating that an obstacle is located when the infrared ray is not received again.

Receives a crime-related signal transmitted from another method device outside of the crime prevention signal receiver 30. For example, other security devices (for example, devices installed on a ceiling or a wall to detect an intrusion or located in a window or a door, intrusions are provided in a predetermined distance except for the security device 1 according to an embodiment of the present invention). Security signals transmitted according to intrusion detection). The security signal receiver 30 may receive a signal transmitted from another security device that performs ZigBee communication or low power communication, for example.

The signal processor 40 processes and outputs signals output from the hot wire detector 10, the distance detector 20, and the crime prevention signal receiver 30 as signals that can be processed by the determiner 50. For example, the process of filtering and amplifying a signal, and the like, and this process can be performed according to a known technique, detailed description thereof will be omitted here.

The determination unit 50 determines whether an intrusion occurs based on the signals of the hot wire detecting unit 10, the distance detecting unit 20, and the crime prevention signal receiving unit 30 provided from the signal processing unit 40. The determination unit 50 may be a detection signal of the hot wire detection unit 10 (hereinafter referred to as a first detection signal for convenience of description) and a detection signal of the distance detection unit 20 (hereinafter, for convenience of description, a second detection signal). And the signal of the crime prevention signal receiver 30 (hereinafter, referred to as a third detection signal for convenience of description) are selectively considered to determine whether an intrusion occurs. The determination method will be described in more detail later.

On the other hand, the determination unit 50 transmits the determination result to the control center (not shown) via the communication unit 60 or to the portable terminal of the administrator. Alternatively, the warning unit 80 may output an optional warning signal. In addition, when an intrusion occurs according to the determination result, the lighting unit 70 may be driven.

The heat ray detecting unit 10 according to an embodiment of the present invention may be implemented in a form including a lens unit and a plurality of sensing modules, and each sensing module collects infrared rays generated from a monitoring target to provide a corresponding electrical signal. It includes an infrared sensor unit for output.

2 is a diagram illustrating a structure of a heat ray detector according to an exemplary embodiment of the present invention.

As shown in FIG. 2, the heat ray detecting unit 10 according to the embodiment of the present invention includes a lens unit 11, a first sensing module 12, and a second sensing module 13. Of course, three or more sensing modules may be included. Here, the heating wire sensing unit 10 will be described with an example of including two sensing modules.

The lens unit 11 collects infrared rays from the monitoring target and sends them to the first and second sensing modules 12 and 13, and in particular, the lens unit 11 according to the embodiment of the present invention is incident from different directions. Form different monitoring zones that focus infrared light. To this end, the lens unit 11 includes a Fresnel lens having a plurality of lens segments having different refractive indices and forming a plurality of monitoring zones.

The first and second sensing modules 12 and 13 include infrared sensor units 121, 122, 131, and 132, and output electrical signals corresponding to changes in the infrared light collected through the lens unit 11. Although a pyroelectric sensor was used as the infrared sensor unit here, it is not necessarily limited thereto. A pyroelectric element is a differential element that outputs an electrical signal when there is a temperature change, and generally does not output a signal for an object that does not move.

In this case, the infrared sensor units 121, 122, 131, and 132 of the first and second sensing modules 12 and 13 may be arranged such that light receiving surfaces receiving light from the lens unit 11 are positioned in different directions.

3 is a cross-sectional view of a sensing module according to an embodiment of the present invention. 3 illustrates the structure of the first sensing module 12 as an example.

As shown in FIG. 3, in the first sensing module 12 according to the exemplary embodiment of the present invention, the infrared sensor units 121 and 122 are incident on the rear end of the incident surface of the lens unit 11 from the lens unit 11. It is arranged so that each can receive. At this time, each infrared sensor unit is disposed in the form of a predetermined angle with respect to the front of the lens unit (11). In detail, the infrared sensor unit 121 is positioned at a position where the center point of the light receiving surface forms a set angle (for example, 72.4 °) with the center line A, so that an angle capable of detecting infrared rays, that is, a sensing angle is predetermined. Disposed at an angle (eg, 135 °). The other infrared sensor unit 122 is also positioned at a position where the center point of the light receiving surface forms a set angle (for example, 72.4 °) with the center line A so that the sensing angle is a predetermined angle (for example, 135 °). Is placed. Accordingly, the total detection angle that can be monitored by the two infrared sensor units 121 and 122 is formed at 270 °. Here, the center line represents a line passing through the center point of the lens unit 11 in front of the lens unit 11, that is, in front of the lens unit 11 facing the surveillance region.

As such, the first sensing module 12 is disposed with respect to the one lens unit 11 facing the incident surface toward the monitoring area, and the first infrared sensor unit 121 and the receiving surface facing the light receiving surface in the first direction are disposed. And a second infrared sensor unit 122 facing in a second direction, wherein a center point of the light receiving surface of the first infrared sensor unit 121 facing in the first direction and the second infrared sensor unit 122 facing in the second direction are included. The center point of the light receiving surface of the first infrared sensor unit 121 and the second infrared sensor unit 122 are disposed to form a preset detection angle. Accordingly, the first sensing module 12 may comprehensively detect the surveillance area by forming an optimal sensing angle.

Similar to the first sensing module 12, the second sensing module 13 according to the exemplary embodiment of the present invention may have the first infrared sensor unit 131 facing the first direction and the receiving side facing the second direction. And a second infrared sensor unit 132, wherein a center point of the light receiving surface of the first infrared sensor unit 131 facing the first direction and a center point of the light receiving surface of the second infrared sensor unit 132 facing the second direction are included. The first infrared sensor unit 131 and the second infrared sensor unit 132 are disposed to form a preset sensing angle.

The first sensing module 12 and the second sensing module 13 according to the embodiment of the present invention having such a structure may be disposed above and below the center line of the crime prevention apparatus, respectively.

4 is an exemplary view illustrating a layout view of first and second sensing modules according to an exemplary embodiment of the present invention.

As illustrated in the accompanying FIG. 4, in the embodiment of the present invention, the first sensing module 12 is disposed at an upper end with respect to the centerline B of the crime prevention apparatus 1, and the second sensing module 13 is disposed. Arranged at the lower end with respect to the center point (B) of the security device 1, it is possible to monitor the monitoring area corresponding to each different position.

The first sensing module 12 and the second sensing module 13 respectively detect infrared rays generated in the monitoring area at a sensing angle of 270 ° and output corresponding electric signals. In particular, in the embodiment of the present invention, the first sensing module 12 detects the infrared rays received through the first monitoring zone through the lens unit 11 in the surveillance area, and outputs a corresponding signal. 13 detects infrared rays received through the second surveillance zone through the lens unit 11 in the surveillance region and outputs a corresponding signal.

5 is an example showing a monitoring zone formed by the lens unit according to an embodiment of the present invention, Figure 6 is an exemplary view showing dual sensing performed by the security device according to an embodiment of the present invention.

When the surveillance region is divided into the first surveillance region R1 and the second surveillance region R2, as shown in FIG. 5, the first surveillance zone Z1 and the second surveillance zone formed by the lens unit 11. Z2 is formed to be parallel to each other in the first monitoring region R1, and is formed to be alternately arranged in the second monitoring region R2.

Specifically, in the first monitoring region R1, the first monitoring zone Z1 is formed at the first height and the second monitoring zone Z2 is formed at the second height lower than the first height, but the second monitoring region ( In R2), the first monitoring zone Z1 and the second monitoring zone Z2 are alternately positioned for each position. For example, in the second monitoring region R2, the first monitoring zone Z1 is formed at the third height, the second monitoring zone Z4 is formed at the fourth height, and then again the second monitoring zone ( Z2) is formed and the first monitoring zone Z1 is formed at the fourth height so that the first monitoring zone Z1 and the second monitoring zone Z2 are alternately formed.

In this manner, the first and second monitoring zones Z1 and Z2 are formed in the monitoring area, and the first sensing module 12 outputs a signal corresponding to the light condensed by the first monitoring zone Z1. The second sensing module 13 outputs a signal corresponding to the light condensed by the second monitoring zone Z2. To this end, the lens unit 11 is made of a Fresnel lens including a plurality of lens segments to collect infrared rays generated in different directions.

As illustrated in FIG. 6, in the state where the hot wire detection unit 10 is embedded in the desk-type security device 1, the first detection module 12 of the hot wire detection unit 10 senses the first detection module 12. When the surveillance zone Z1 and the second surveillance zone Z2 sensed by the second sensing module 13 are formed and a person enters the surveillance zone, the first surveillance zone Z1 and the second surveillance zone Z Z2) is positioned, so that the first sensing module 12 and the second sensing module 13 simultaneously output the first sensing signal.

However, when pets such as dogs enter the surveillance zone, they are usually smaller than humans, so they are only detected in one surveillance zone. For example, when the animal moves from the bottom, it is detected only in the second monitoring zone Z2. In contrast, when the animal is located at a predetermined height such as a sofa, it may be detected only in the first monitoring zone Z1. Therefore, the determination unit 50 according to an embodiment of the present invention determines that a person has invaded when the first detection signals are simultaneously output from each of the detection modules 12 and 13 of the hot wire detection unit 10, and any one of them is determined. If the first detection signal is output from the module of the animal is determined to be detected, it may be determined that the intrusion is not. According to such dual sensing, it is possible to prevent unnecessary response processing due to a false intrusion warning by an animal such as a pet left alone indoors.

You can also easily detect when an intruder leans over. Specifically, when the first surveillance zone Z1 and the second surveillance zone Z2 are not arranged in the second surveillance region R2 but arranged in the same form as the first surveillance region R1, a human body If it moves down, it is detected only in the monitoring zone located at the bottom, for example, the second monitoring zone (Z2). In such a case, it is likely that the target is not a human because it is detected only in one monitoring zone. However, according to an exemplary embodiment of the present invention, since the first monitoring zone Z1 and the second monitoring zone Z2 are alternately arranged in the second monitoring region R2, even when a person invades and moves, As the signals according to the detection are output from the first monitoring zone Z1 and the second monitoring zone Z2, it is possible to easily detect whether an intrusion is detected by determining that the detected target is a human. In this case, the first monitoring zone Z1 and the second monitoring zone Z2 may be alternately arranged on the basis of the height considering the case where the person is bowed down in the second monitoring region R2. Accordingly, when the signals from the first and second sensing modules 12 and 13 are simultaneously output or respectively output within the set time, it is determined that the person is a person. May not be determined.

The desk-type security device 1 according to the embodiment of the present invention having such a structure is implemented in the following table type.

7 is an external perspective view of a security device according to an embodiment of the present invention, Figure 8 is a cross-sectional view of the security device.

As illustrated in FIG. 7, the security apparatus 1 according to the embodiment of the present invention is implemented as a desk type that can be installed on a desk, etc., and can be easily installed at a predetermined position of the monitoring area, and also can serve as a mood lighting function. Implemented in the form of a table, it can provide a lighting function as well as a security function.

To this end, the anti-theft device 1 according to an embodiment of the present invention, as illustrated in Figure 8, is made of a form including a support (SU) and the body (BD) connected to and supported by the support (SU), The body B1 is configured to include a storage space S1.

The lighting unit 70 is positioned at the upper end of the body BD, and the security signal receiving unit 30, the signal processing unit 40, the determination unit 50, the distance sensing unit 20, and the communication unit 60 are mounted on the body BD. Warning unit 80 may be built. In addition, the hot wire detection unit 10 is inserted into the storage space S1 of the body BD and connected to the body BD, and is connected to the signal processor 40 embedded in the body BD. In particular, the storage space (S1) of the body (BD) is formed in the direction (front) of the security device 1 toward the monitoring area in order to facilitate the detection of the monitoring target, and thus a heating wire inserted into the storage space (S1) The detector 10 may detect infrared rays from the monitoring target.

Although not shown, the distance sensor 20 is located in a direction toward the monitoring area, such as the hot wire detection unit 10, to transmit infrared rays to a monitoring target and detect whether infrared rays are reflected. The signal processing unit 40 and the determination unit 50 are installed in the form of the rear portion, not the front portion of the security device 1, and processes the signals output from each of the detection unit 10, 20 and the receiver 30 Then determine whether an intrusion has occurred. The communication unit 60 may be implemented in a form installed at the bottom of the crime prevention apparatus (1).

As the security device 1 is made in an all-in-one form including all the components and has a tabletop shape, no wiring work is required to connect to the communication device. If only the connection of the anti-theft device (1) can be installed anywhere. Accordingly, a security device can be easily and easily installed in a desired area without drilling or wiring work for installation on a ceiling or a wall. On the other hand, although the table-type security device (1) described here includes all the hot wire detection unit 10, the distance detection unit 20, the security signal receiving unit 30, on the contrary, the table-top security device (1) Any one of the three components of, for example, may be implemented only in the form including a heat ray detection unit.

On the other hand, such a desk-type security device (1) can be installed in the form to be installed on the table, as shown in FIG.

9 is a view showing an installation example of the desk-type security device according to an embodiment of the present invention.

The security device 1 may be installed on a table to detect a surveillance area. In this case, an obstacle may be installed in front of the security device 1. In this case, despite the fact that intrusion has occurred, the hot wire detection unit 10 may not detect the infrared rays generated from the monitoring object due to the obstacle. Accordingly, when the determination unit 50 according to the embodiment of the present invention does not output the signal according to the detection of the predetermined object from the distance detection unit 20 even though the signal according to the intrusion detection is output from the hot wire detection unit 10. It is determined that there is an obstacle in front of the crime prevention apparatus 1, and transmits a signal corresponding thereto to the mobile terminal of the control center or the administrator through the communication unit 60, or detects the intrusion by the obstacle or the like through the warning unit 80. Notifies that it is not done normally. In this case, the determination unit 50 may output a signal indicating that there is an obstacle through the warning unit 80 as an audio signal such as a voice.

In addition, the determination unit 50 does not output the first detection signal from the heating wire detection unit 10 even though the third detection signal corresponding to the security signal transmitted from the security signal reception unit 30 from another security device is output. In this case, it can be determined that no intrusion occurs. On the contrary, even if the first detection signal from the hot wire detection unit 10 is not output, it may be determined that an intrusion has occurred when the third detection signal corresponding to the security signal transmitted from another security device is output.

Looking at the crime prevention method using a desk-type security device composed of such a structure, as follows.

10 is a flowchart illustrating a crime prevention method according to the tabletop security device according to an embodiment of the present invention.

In the state where the table-type security device 1 according to an embodiment of the present invention, for example, on a table located in the monitoring area as shown in Figure 9 (S100), from the security signal receiver 30 from other security equipment When the first detection signal is output from the hot wire detection unit 10 while the third detection signal indicating the intrusion is not output, it is determined whether the second detection signal according to the predetermined object detection is output from the distance detection unit 20. Determine (S110 ~ S130). When the second detection signal is not output while the first detection signal is output, it is determined that an obstacle is located in front of the crime prevention apparatus 1, and a corresponding abnormal occurrence signal is controlled through the communication unit 60. Transmission to the mobile terminal of the center or the manager or output through the warning unit 80 (S140).

On the other hand, when the second detection signal according to intrusion detection is also output from the distance detection unit 20 while the first detection signal is output from the hot wire detection unit 10, the determination unit 50 is the hot wire detection unit 10. It is determined whether the first sensing signal is output from all sensing modules of the first sensing signal or only the first sensing signal from only some sensing modules (S150).

In detail, the determination unit 50 outputs a first detection signal indicating that a predetermined object is detected in the first monitoring zone by the first detection module 12 of the hot wire detection unit 10, and the second detection module 13. In response to the first detection signal indicating that the predetermined object is detected in the second monitoring zone, it is determined that the person is detected (S160). In such a case, it is determined that an invasion has occurred by a person, and the processing operation according to the invasion occurs, for example, the determination unit 50 transmits the intrusion occurrence to the control center (not shown) through the communication unit 50 or the administrator. Transmission to the mobile terminal (S170). In this case, it may be determined that an intrusion has occurred when both the first sensing signal 12 and the second sensing module 13 are simultaneously output.

Meanwhile, when the first detection signal is output only from one of the first detection module 12 and the second detection module 13 of the hot wire detection unit 10, the determination unit 50 may not be a person. For example, it is determined that a pet such as a dog is detected (S180). In this case, the processing operation according to the intrusion is not performed. Through this process, it is possible to effectively prevent the detection of intrusion by detecting an object except a person such as a pet.

On the other hand, in the above step (S110), when the third detection signal indicating the occurrence of intrusion from the other crime prevention device from the crime prevention signal receiving unit 30, whether or not the detection of the hot wire detection unit 10 or the distance detection unit 20 Regardless, it is determined that an intrusion has occurred and thus a warning signal corresponding thereto may be transmitted to the mobile terminal of the control center or the administrator through the communication unit 60 or output through the warning unit 80.

Meanwhile, when the first detection signal is not output from the hot wire detection unit 10 in step S120, the determination unit 50 determines that the intrusion does not occur (S190). Unlike this, however, if the first detection signal is not output but the second detection signal is output by the distance detecting unit 20, it may be determined that an intrusion has occurred and an operation according to the intrusion may be performed.

In the above-described security method, it is determined whether an intrusion occurs by comprehensively considering the first to third detection signals output from the hot wire detecting unit 10, the distance detecting unit 20, and the security signal receiving unit 30, respectively. Although the operation has been described, the security operation may be performed to determine whether an intrusion occurs based on only one detection signal without being limited thereto. For example, regardless of the detection signals of the distance detector 20 and the crime prevention signal receiver 30, it is possible to determine whether an intrusion occurs based on only the detection signal from the hot wire detection unit 10.

In addition, regardless of whether the first detection signal is output from the hot wire detection unit 10, when the second detection signal is output from the distance detection unit 20, it is determined that there is an obstacle in the monitoring direction of the crime prevention apparatus 1. can do. When there is an obstacle as described above, the warning unit 80 may notify that there is an obstacle or the communication unit 60 may transmit a signal indicating that there is an obstacle.
