Description

[0001] APPARATUS FOR DETECTING INTRUSION [0002]

The present invention relates to an intrusion detection device for detecting an intrusion target by using information received from a sensor, displaying it on a screen when it is determined to be a dangerous object, and generating a notification selectively.

In all areas of border activity, ie military, police, security and building security zones, the border is mainly carried out by people. However, in the nighttime, it is not possible to secure the reliability of the bounding work activity because of the drowsiness and the concentration loss as well as the limit of the audiovisual recognition ability of the human being.

Therefore, the development of detection devices that monitor and judge themselves and take appropriate action when there is a danger has continued. However, the intrusion detection device can not perform its own bounding task yet, but it has a problem that it only serves to assist the person standing at the boundary. Therefore, there is a need for an intrusion detection device which does not depend on the human auditory perception ability.

Korean Prior Art No. 10-1161405 (entitled " fence boundary device using image and USN ", published on May 23, 2012) is a related prior art.

The present invention provides an intrusion detection device for detecting a type of an object appearing in a boundary area using information received through various sensors, determining a risk, and generating other notifications according to the object.

Preferably, the analyzing unit may determine whether an intrusion has occurred by using the calculated intrusion risk index based on the number and type of the received sensing information and the weight assigned to each type of the sensing information.

Preferably, when a position transmitter for encrypting and repeatedly transmitting the current position information received from the GPS is attached to the personal equipment worn or carried by the individual, the information receiver receives the position information from the position transmitter attached to the personal equipment, And the display unit may further display an allowance point corresponding to the position information received from the position transmitting apparatus so as to be distinguished from the preliminary intrusion point and the intrusion point.

Advantageously, the analysis unit can ignore the sensing information received from the plurality of sensors located within a predetermined distance from the allowance point.

Preferably, the analyzing unit may further calculate a type of the object, a moving speed, and a distance from the infrared camera to the object based on the size and shape of the object included in the infrared image information photographed from the infrared camera .

The present invention has an effect of analyzing information detected from various sensors without human assistance and judging whether an intruder is intruding or not, displaying the intruding information on a screen, generating a notification, or transmitting the information to the outside.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an intrusion detection apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the intrusion detection apparatus 100 includes an information receiving unit 110, an analyzing unit 120, a display unit 130, and a notification unit 140. Meanwhile, the intrusion detection device 100 of the present invention can be mounted on a desktop computer or a notebook computer.

The information receiving unit 110 receives sensing information from a plurality of sensors distributed in a boundary area.

The boundary target area is an area in which a continuous boundary condition is to be maintained for intrusion detection. The type and number of a plurality of sensors installed according to the area, the terrain and the surrounding environment (natural environment, building, road, etc.) Can be determined. A further description of the boundary area will be described later in the description of FIG.

The plurality of sensors include a motion detection sensor for detecting movement, an infrared camera for capturing infrared image, an ultrasonic sensor for detecting an obstacle by emitting ultrasonic waves, a vibration detection sensor for detecting vibration, a sound detection sensor for detecting sound, And at least one sensor of at least one of the load sensors may be included.

For example, it is possible to construct a sensor system for alerting a specific boundary area by using two infrared cameras, two ultrasonic sensors, and one sound sensor. Preferably, each sensor and camera should be appropriately dispersed and disposed so as to cover all the boundary regions.

Meanwhile, the sensing information may be generated differently depending on the type of each sensor and the content of the information, and an electronic device for transmitting the generated sensing information to the information receiving unit 110 may be connected to each sensor. The electronic device can transmit detection information to the information receiving unit 110 by wire or wireless, and Bluetooth, wireless LAN, ZigBee, or the like can be used for wireless connection.

For example, sensing information including an infrared image may be generated from an infrared camera, and sensing information including magnitude (weight) information of a sensed load may be generated from a load sensor.

The sensing information may also include information about the time at which the information was sensed. This may be to use the time information as means for synchronizing a plurality of sensed sensed information.

The analyzer 120 synchronizes the received detection information based on time and determines whether or not an intrusion occurs.

Since the sensing information is generated from different types of sensors, the deviation between the time at which each sensing information is generated and the time at which the information is received by the information receiving unit 110 may be different for each sensor. Accordingly, the analyzer 120 may synchronize the received sensing information based on the information about the time at which the sensing information is generated, and then use the synchronized sensing information to determine whether an intrusion has occurred.

For example, when a plurality of pieces of sensing information received from different sensors have an error time of less than 10 seconds, the plurality of pieces of sensing information can be regarded as being generated at the same time, It can be used to determine whether an intrusion has occurred or not.

In another embodiment, the analyzer 120 determines whether an intrusion has occurred by using the calculated intrusion risk index based on the number and type of the sensed information received during a predetermined time interval and the weight assigned to each type of sensed information .

The calculation of the invasion risk index can be performed using the following equation (1).

Here, S is the invasion risk index, n is the total number of types of sensing information received during a predetermined time interval, a _j is a weight assigned to the jth sensing information class, n _j is a weight J < / RTI >

For example, when two pieces of detection information are received for each of three kinds of detection information types, the intrusion risk index can be calculated as S = 0.5 * 2 + 1 * 2 + 0.7 * 2. (However, the weights of the three types of detection information types are 0.5, 1, and 0.7, respectively.)

The predetermined time interval may be preset by the user in a time interval for determining whether or not an intrusion has occurred. At this time, the user may be an administrator or a user of the intrusion detection apparatus 100.

The type of the sensing information may be determined according to the sensor from which the sensing information is generated. For example, a plurality of pieces of sensing information generated from a sound sensing sensor may be the same kind of sensing information, but sensing information generated from a sound sensing sensor and sensing information generated from a motion sensing sensor are different types of sensing information can do.

In addition, the weight for each kind of sensing information can be given based on the reliability in detecting the intrusion for each kind of sensing information. That is, when the detection information is generated, a higher weight can be given to the kind of the detection information that is highly likely to be determined as an intrusion. Conversely, when the detection information is generated, a lower weight value can be given to the type of the detection information that is less likely to be determined as an intrusion.

For example, referring to FIG. 3, a relatively high weight can be given to sensing information generated from an infrared camera capable of identifying the size and shape of an object, and a sound, The sensing information generated from the sensing sensor may be given a relatively low weight.

The analysis unit 120 can determine that an intrusion has occurred when the calculated intrusion risk index is equal to or greater than a predetermined threshold value and can determine that no intrusion has occurred when the intrusion risk index is smaller than the threshold value.

On the other hand, the threshold value used as a criterion for determining whether an intruder is intruded or the weight value of each type of detection information can be set by the user, and can be used as a means for controlling the sensitivity of the intruder determination.

In another embodiment, the analyzer 120 further calculates the type of the object, the moving speed thereof, and the distance from the infrared camera to the object based on the size and shape of the object included in the infrared image information photographed from the infrared camera .

That is, when the infrared camera is installed to photograph the boundary region, information on the object included in the image information can be further calculated using the infrared image information photographed from the infrared camera. At this time, the calculation of the object type, the moving speed and the distance using the infrared camera can be more effectively used at night where it is difficult to observe by the human visual ability.

For example, the analyzer 120 can determine the type of the object by extracting the shape of the specific object shown in the infrared image information and comparing it with the representative shape of each object type stored in the DB. For example, the DB may store a representative shape of an object likely to appear in an object area such as a person, a wild boar, a deer, a car, a bicycle, a motorcycle, and a tank.

In addition, the analyzer 120 may calculate the corresponding movement speed and distance based on the size of the object shown in the infrared image information. For example, the analyzer 120 stores information on the size of an object by distance from an infrared camera on the basis of a standard key (for example, 170 cm) of an adult male, so that the size of the human shape object included in the infrared image information The distance from the infrared camera to the object can be calculated. In addition, the analyzer 120 may calculate the moving distance by calculating the moving distance of the object from the size change of the object.

The display unit 130 displays information about the boundary area, a pre-entry point corresponding to the received detection information, and an intrusion point determined as an intrusion from among the pre-entry points.

For example, when the display unit 130 displays a photograph or a picture at a time when the boundary region is viewed from the sky on a display device such as an LCD monitor or a TV as a background and a white triangular mark And an intrusion point determined as an intrusion can be displayed using a red X-shaped marking.

The preliminary intrusion point may be a point at which the detection information is estimated based on the position of the generated sensor. For example, the preliminary intrusion point may correspond to a position corresponding to the position of the load sensor for the sensing information generated from the load sensor, a position corresponding to the sensing information generated from the motion sensing sensor, And the sensing information generated from the sound sensing sensor may be a position corresponding to a position distant from the microphone in a direction toward the microphone.

The intrusion point may be a point where it is determined that an intrusion has occurred as a result of analysis by the analysis unit 120 among the preliminary intrusion points. In addition, the information about that intrusion point may be flickered or marked larger than the pre-intrusion point to increase the effect of the warning to the user.

The notification unit 140 selectively outputs or transmits a notification signal based on the determination result of the analysis unit 120. [

For example, when the analyzer 120 determines that an intrusion has occurred, the notification unit 140 may output a warning message on the screen of the computer in which the intrusion detection apparatus 100 is installed, and a warning sound through the speaker. In addition, notification signals can be transmitted to other predetermined computers and smart devices such as smart phones and tablet PCs. At this time, other computers and smart devices can be located externally and can transmit notification signals through a separate network (e.g., 3G, LTE network) connected thereto.

On the other hand, the notification unit 140 can change the object and the number of output and transmission of the notification signal based on the possibility of the occurrence of the intrusion determined by the analysis unit 120. [

In another embodiment, when a position transmitter for encrypting and repeatedly transmitting current position information received from the GPS is attached to an individual device worn or carried by a person, the information receiver 110 may transmit the location information The display unit 130 may further receive detection information including positional information from the transmission device, and the display unit 130 may further display an allowance point corresponding to the positional information received from the position transmission device so as to be distinguished from the preliminary intrusion point and the intrusion point.

When the position transfer apparatus is required to perform another operation (e.g., cleaning work or construction work) regardless of the intrusion at the boundary target area, the intrusion detection apparatus 100 can be operated by the worker It can be used to prevent workers from being recognized as intruders.

At this time, the position information of each worker is received from the GPS mounted on the position transmitting apparatus, and the position information thereof can be encrypted using a predetermined encryption key for security reasons. Then, the position transmitter can transmit the encrypted position information to the information receiver 110 at predetermined time intervals.

On the other hand, the display unit 130 may further display the detection information including the information on the allowable point so as to be distinguished from the preliminary intrusion point and the intrusion point. For example, a yellow circle mark can be used to indicate the allowance point.

In another embodiment, the analysis unit 120 may ignore the sensing information received from the plurality of sensors located within a predetermined distance from the allowance point.

That is, it may be unnecessary for an operator carrying the position transmitter to be detected by a sensor installed in a boundary region and to determine whether the analyzer 120 uses the detection information to enter the boundary region. Therefore, the analysis unit 120 may not use the detection information received from the sensor located within a predetermined distance from the allowable point, which is assumed to be the location of the operator carrying the position transmitter, to determine whether or not the intruder is intruding.

As described above, the intrusion detection apparatus 100 according to an embodiment of the present invention has the effect of always detecting an intruder of an outsider to a boundary region by using a plurality of sensors without continuous observation of a person. In addition, it is possible to maximize the effect of the intrusion detection device 100 at night, especially by using an infrared camera.

2 is a view for explaining a boundary area according to an embodiment of the present invention.

Referring to FIG. 2, the boundary area may be a place where continuous monitoring of an intrusion is required, and a plurality of sensors 220 are installed for effective intrusion detection on major facilities such as a trolley 210 located in the place .

For example, it may be a key point such as a fleet near an iron-clad railroad where enemy troops are likely to infiltrate, an arsenal such as an arsenal, or an area where an article is likely to be stolen. At this time, sensors can be installed intensively in locations where the intruder is likely to go through (eg, in front of a railroad track, a bridge, a building entrance, etc.) so that an intruder can be more easily detected in a boundary area.

The above-described embodiments of the present invention can be embodied in a general-purpose digital computer that can be embodied as a program that can be executed by a computer and operates the program using a computer-readable recording medium.

The computer readable recording medium includes a magnetic storage medium (e.g., ROM, floppy disk, hard disk, etc.), optical reading medium (e.g., CD ROM, DVD, etc.).

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
