[First embodiment]

1 is a cross-sectional view of a sensing device according to a first embodiment of the present invention.

In FIG. 1 , the sensing device 1 includes a plurality of metal rods 110 , 120 , 130 , 140 disposed to be spaced apart from the ground by a predetermined distance in the vertical direction, and a plurality of metal rods 110 , 120 , 130 and 140 , respectively. It is composed of a plurality of oscillation coils 210 , 220 , 230 , 240 formed by winding and a PCB 300 .

The PCB 300 is connected to the plurality of oscillation coils 210, 220, 230, 240, respectively, and a plurality of oscillation units oscillating a set sensing frequency, and detects a change in the oscillation frequency output from the plurality of oscillation units to invade An intrusion determination unit for determining whether or not is configured.

An insulator-type buffer 21 is formed between the plurality of metal rods 110 , 120 , 130 , and 140 in order to reduce the effect of mutual interference between adjacent oscillation coils.

In addition, in order to protect the plurality of oscillation coils 210 , 220 , 230 , 240 , a plastic protective case 11 is configured outside.

A fixing plate 31 is configured on the bottom surface to fix the plurality of oscillation coils 210, 220, 230, 240 and the protective case 11 to the ground, and the fixing plate 31 protects the PCB 300, It is preferable to be formed of a plastic material or a metal material that can be firmly supported on the ground.

In addition, the plurality of metal rods 110 , 120 , 130 , 140 may be made of metal such as aluminum, and in this embodiment, a non-conductive peeling tape 41 surrounds the metal rod 110 , and the peeling tape 41 . It has a structure to configure the oscillation coil 210 by winding the enamel wire.

Meanwhile, the plurality of metal rods 110 , 120 , 130 , 140 may be provided with a sensor 5 , for example, an ultrasonic sensor. The sensor 5 may be managed by the control unit 460 of FIG. 2 by assigning a corresponding number to each metal rod. That is, by giving a sensor number and a metal rod number, it is possible to determine which sensor is attached to which metal rod.

In this state, the sensor 5 transmits a signal toward the adjacent metal rods, inputs the returned signal to the control unit 460 to process it, and as a result of the processing, for example, when the distance between the metal rods exceeds the reference distance, It is judged that the metal rod cannot maintain its normal position, and appropriate measures are taken.

The appropriate action is to display an alarm sound, an alarm message, an alarm message, etc. to the outside through the alarm unit and the display unit under the control of the control unit 460, and furthermore, the administrator puts the metal rod out of the normal position in a normal position. may include

FIG. 2 is a control configuration diagram of the sensing device of FIG. 1 .

In FIG. 2, the sensing device 1 is connected to the plurality of oscillation coils 210, 220, 230, 240 and the plurality of oscillation coils 210, 220, 230, 240, respectively, and detects a set detection frequency. A plurality of oscillating units 310, 320, 330, 340, and a plurality of oscillation frequencies (F1, F2, F3, F4) output from the plurality of oscillation units 310, 320, 330, 340 detect changes in and invade Consists of an intrusion determination unit 400 that determines whether or not.

The intrusion determination unit 400, a frequency counter (410, 420, 430, 440) for counting a plurality of oscillation frequencies (F1, F2, F3, F4), and a reference frequency (REF) and the frequency counter (410, Comprising a comparison unit 450 that compares the counted frequencies (F1_O, F2_O, F3_O, F4_O) at 420, 430, and 440, and a control unit 460 that determines an intrusion based on the comparison result of the comparison unit 450. do.

The first oscillation unit 310 constitutes an oscillation circuit together with the first oscillation coil 210 , the second oscillation unit 320 constitutes an oscillation circuit together with the second oscillation coil 220 , and the third oscillation unit 330 . constitutes an oscillation circuit together with the third oscillation coil 230 , and the fourth oscillation unit 340 constitutes an oscillation circuit together with the fourth oscillation coil 240 .

In this case, all of the plurality of oscillation units 310 , 320 , 330 , and 340 may be configured to oscillate the same oscillation frequency. The range of the oscillation frequency may be set within the range of several hundred hertz to several hundred thousand hertz.

On the other hand, although the present embodiment exemplifies the configuration of the sensing device 1 using four oscillation coils and an oscillation unit, the number of oscillation coils and oscillation units may be adjusted according to a height to be sensed.

The frequency counter (410, 420, 430, 440) of the intrusion determination unit 400 is composed of four, after counting the oscillation frequency of each oscillation unit (310, 320, 330, 340), the counted frequency (F1_O, F2_O) , F3_O, F4_O).

The comparator 450 compares the reference frequency REF with the counted frequencies F1_O, F2_O, F3_O, and F4_O, and outputs a result of whether a frequency change has occurred.

Based on the comparison result of the comparison unit 450, the control unit 460 determines (DET) whether there is a caution, a warning, and an intrusion in consideration of the detection height.

Next, the principle of the sensing device 1 of the present invention detecting an object, that is, an animal or a person will be described as follows.

If a moving object, particularly an animal, approaches the pipe-type sensing device 1, the impedance of the oscillation coil increases due to a change in magnetic flux of the oscillation coil corresponding to the height of the animal from the ground.

Therefore, the oscillation unit connected to the oscillation coil and oscillating a specific oscillation frequency initially oscillates a certain oscillation frequency for sensing, but when an object approaches, the impedance increases and the frequency gradually slows down.

Meanwhile, when an object approaches, the sensing device 1 may be configured such that the frequency gradually increases.

The intrusion determination unit 400 detects a change in the frequency to determine whether there is an intrusion, and determines whether attention, warning, and intrusion according to the detection height.

First, when the oscillation frequencies are simultaneously changed by the oscillation coils disposed at the position of the first height H1 from the ground, it is determined as intrusion. In this case, the first height H1 is preferably set to a height of a person, a sitting height, or a height when moving while lying face down.

Next, it is determined as a warning when the oscillation frequency is changed by the oscillation coils disposed below the second height H2, which is lower than the first height H1, from the ground. The second height H2 may be set in consideration of a height of an animal that can be distinguished from a human in size or a height of an animal that appears frequently.

Next, it is determined with caution when the oscillation frequencies are changed by the oscillation coils disposed at a position higher than the first height H1. Since a person cannot continuously move to a height higher than the first height H1, such a sensing range may be inferred to an animal such as a bird.

Finally, when the oscillation frequencies by all the oscillation coils change simultaneously within a certain range, it is determined that there is no invasion. That is, when lightning strikes, etc., the intrusion determination unit 400 detects a waveform of a very short pulse shape. .

3 is a circuit diagram of an oscillator according to an embodiment of the present invention.

The oscillation unit of FIG. 3 is a 'Clapp' type oscillation circuit.

In FIG. 3 , the oscillator 310 includes an LCD oscillator 311 having an oscillation coil 210 , an amplifier 312 , and a buffer 313 .

The LCD oscillator 311 oscillates a frequency set by a passive element.

The amplifier 312 amplifies the oscillation signal by the LCD oscillator 311 .

The buffer 313 buffers the oscillation signal amplified by the amplifier 312 and outputs it to the outside.

The buffer 313 may be configured to buffer a signal, or may be configured as a waveform shaping circuit for converting a signal having a specific waveform.

In addition, the circuit configuration of the oscillator 310 may include a crystal oscillator, and various types of oscillation circuits may be used according to embodiments.

4 is a waveform diagram illustrating a detection waveform of the sensing device of FIG. 1 .

Referring to the waveform diagram of FIG. 4 , when an object, for example, a person or an animal, does not approach the sensing device 1 as described above, a uniform oscillation frequency is continuously sensed.

However, when a person or an animal approaches, the oscillation frequency of the oscillation part corresponding to the height of the person or animal from the ground gradually becomes slower as the person or animal approaches.

On the other hand, when lightning strikes, a waveform with a very short and strong voltage appears. Therefore, it is possible to distinguish between when an animal including a human approaches and when a natural phenomenon, especially a lightning strike, occurs.

In addition, even in situations other than lightning, such as rain, snow, and fog, a waveform with a slower or faster frequency may be detected, but since this occurs uniformly at all heights, an object approaching within a certain range and natural phenomena.

In addition, in consideration of the detected height, it is possible to distinguish between humans and animals within a certain range.

On the other hand, the sensing device of the present invention may further include a wired or wireless communication module for transmitting the determination result of the intrusion determination unit, and may further include an alarm unit for alerting the determination result through sound or light.

In addition, the sensing device of the present invention may be manufactured as a waterproof type so that it can be disposed in water.

Meanwhile, as another embodiment, the oscillation coil may have a structure capable of simultaneously forming a capacitance and an inductance. To this end, the oscillation coil may be configured as a spiral coil. The spiral coil may be made of a wire or a PCB, and may have a two-dimensional or three-dimensional structure.

5 is a plan view showing a two-dimensional spiral coil according to an embodiment.

6 and 7 are simplified circuit diagrams of the detection unit of FIG. 5 .

FIG. 6 is a schematic diagram of a parasitic capacitance component present in the two-dimensional spiral coil shown in FIG. 5 , and FIG. 7 is an equivalent circuit diagram of FIG. 6 .

6 and 7, since the spiral coil can form inductance and capacitance at the same time, it can be adopted as the oscillation coil of the sensing device according to the present technology.

In order to detect changes in capacitance and inductance, there are several methods such as configuring a self-oscillator using an LC circuit to detect changes in oscillation frequency, or applying a reference signal having a constant frequency to the LC circuit to detect changes in amplitude and phase. Several methods may be used.

The frequency of the self-oscillator using the LC circuit is determined by the values of L and C.

In an oscillator using an LC circuit, the L component is an oscillation coil including a spiral coil, and if an object is adjacent to the oscillation coil and causes an increase in capacitance or an increase in inductance, the oscillation frequency (f0) is lowered, and the When the decrease is caused, the oscillation frequency f0 increases.

In general, when an object is adjacent to a sensing device and an eddy current is formed, the inductance decreases, and when a ferritic magnetic material is adjacent to each other, the inductance increases. On the other hand, if there is no decrease in charge due to leakage current, capacitance increases when an object is adjacent to each other.

Accordingly, it is possible to detect whether an adjacent object is a conductor or an insulator, or has both a capacitance component and an inductance component, and to what extent, based on the inductance change amount and the capacitance change amount.

As an example, it is assumed that an arbitrary object having a capacitance is brought close to the oscillation coil.

In the case of a conventional capacitive sensor, when an object is brought into proximity, the frequency f0 of the oscillator constituting the sensing circuit will be reduced only by the increase in capacitance (+ΔC). On the other hand, when an arbitrary object is brought close to the sensing device proposed in this technology, the capacitance increase (+ΔC) depending on the characteristics of the oscillation coil, the value of the capacitor (C) constituting the oscillator together with the oscillation coil, and the conductivity of the adjacent object. ) and inductance decrease (-ΔL) appear differently, and accordingly, the amount of change in the oscillation frequency appears differently. Here, the characteristics of the oscillation coil may include a size, an inductance value, a shape, and the like.

8 is a diagram for explaining the relationship between the amount of change in capacitance and the amount of change in inductance according to the approach of an object.

Referring to FIG. 8 , when the decrease in inductance (-ΔL) is greater than the increase in capacitance (+ΔC) caused by an arbitrary object adjacent to the oscillation coil, the oscillation frequency of the oscillator increases (f0+Δf).

On the other hand, when the increase in capacitance (+ΔC) is greater than the decrease in inductance (-ΔL), the oscillation frequency of the oscillator decreases (f0-Δf).

Therefore, if an object having low conductivity and high dielectric constant, such as a human body, is adjacent to the oscillation coil, the oscillation frequency f0 will decrease.

[Second embodiment]

9 is a block diagram of an intrusion detection system according to a second embodiment of the present invention.

In FIG. 9 , the intrusion detection system 2 includes a plurality of detection devices 500 and a monitoring device 600 .

Each of the plurality of sensing devices 500 may have the same configuration as the sensing device 2 of FIG. 2 .

The plurality of sensing devices 500 are installed at regular intervals in an area requiring monitoring. The installation method may be arranged at regular intervals in a line, such as an iron fence or a fence, and may be arranged in a specific doorway or window.

In addition, the plurality of sensing devices 500 may be two-dimensionally disposed in a space of a certain range overgrown with bushes.

In addition, the plurality of sensing devices 500 may be disposed in a predetermined space in the water, such as a water channel.

Since the intrusion detection system 2 is basically composed of pipe-type detection devices, as described above, determining whether an intrusion is made in consideration of the height is the same as described above.

However, since the intrusion detection system 2 according to the present embodiment is composed of at least one or more detection devices, the determination result between these detection devices is combined to finally determine whether there is an intrusion.

The monitoring operation of the intrusion detection system 2 according to the present embodiment will be described in detail as follows.

The monitoring device 600 of the intrusion detection system 2 finally determines whether there is an intrusion through the determination result of a plurality of intrusion determination units allocated to the plurality of detection devices 500 respectively. That is, the monitoring apparatus 600 determines the size of the object, the movement speed of the object, The movement height and movement pattern, etc. are grasped to determine whether an intrusion has occurred.

That is, since the distance between the sensing devices is already set, the moving speed of the object can be calculated by considering the sensing timing between the adjacent sensing devices. Therefore, considering the moving speed and the sensing range of the sensed object, it can be inferred by dividing, for example, whether a vehicle is moving, a person is moving, or an animal is moving.

In addition, since the movement pattern of an animal that moves while jumping, such as an elk, is clearly distinguished from a human, it can be more accurately determined whether the animal is a human when considering the movement speed and the movement pattern.

In addition, in consideration of the movement patterns of animals frequently appearing in the area where the intrusion detection system is installed, it is possible to more accurately determine whether an intrusion has occurred.

That is, in the intrusion detection system 2 proposed in this embodiment, since a plurality of detection devices 500 are two-dimensionally arranged, it is possible to determine whether an intrusion has occurred through a frequency change according to a movement pattern and speed of a monitoring target.

In addition, since each detection device individually determines whether or not an intrusion occurs according to the height, as a result, the intrusion detection system 2 can monitor a certain area in which a plurality of detection devices 500 are installed in a three-dimensional space. .

For reference, the oscillation frequencies used by the plurality of sensing devices 500 may all be set to have the same frequency. It may be set to have a frequency.

In addition, the plurality of sensing devices and the monitoring device may be connected by wire, and may be configured to transmit/receive data wirelessly by including a wireless communication module according to an embodiment. In particular, when data is transmitted/received through wired and wireless communication modules, it is preferable that a unique ID is assigned to each sensing device.

10 is an exemplary installation diagram of the intrusion detection system described in the first and second embodiments of the present invention.

Referring to FIG. 10 , a plurality of sensing devices 1_1 , 1_2 , 1_3 , 1_4 , and 1_5 are arranged in the horizontal direction at regular intervals around the fence. The separation distance between the plurality of detection devices 1_1, 1_2, 1_3, 1_4, and 1_5 can be adjusted in consideration of the detection sensitivity of each detection device, and the plurality of detection devices 1_1, 1_2, 1_3, 1_4, 1_5 is a fence. It can be installed inside or outside.

[Third embodiment]

11 is a block diagram of an intrusion detection system according to a third embodiment of the present invention. 12 and 13 are diagrams illustrating installation of the intrusion detection system described in the third embodiment of the present invention.

In the third embodiment, the non-metal detection coil 610, the organism detection coil 620, and the metal detection coil 630 are attached to the pipe such as the support 11 of FIG. configured to oscillate at 700 . The arrangement order of the coils from top to bottom may be variable.

In addition, the frequency oscillated by the frequency oscillator 700 by the operation of the coils 610 , 620 , and 630 is compared with a reference value in the frequency analyzer 800 so that the controller 900 determines whether the frequency is changed.

That is, in the third embodiment, by distinguishing and oscillating metal, non-metal, and organism, it is possible to distinguish whether the signal is a detection signal by intrusion, a detection signal by an animal, or a detection signal by a natural phenomenon.

13, assuming that the non-metal sensing coil 610, the organism sensing coil 620, and the metal sensing coil 630 are sequentially configured vertically from top to bottom, the non-metal sensing coil 610 is not touched by a person. To detect the approach of birds, etc., the metal detection coil 630 allows a person to detect the approach of a person holding a metal tool while standing or lying face down, and the organism detection coil 620 is used for other animals, for example It is configured in an appropriate position to detect an approaching animal with lifting power.

However, the arrangement height of the coils as described above may vary. That is, if the positions of the coils are appropriately set according to the height as shown in FIG. 1 and configured, the approach of humans, animals, and other organisms can be efficiently detected.

12 is a view showing that the non-metal detection coil 610, the organism detection coil 620, and the metal detection coil 630 are horizontally sequentially configured to detect the approach of a person possessing a metal tool or an animal with jumping power. be able to do

If the abnormal object that appears in the frequency range is a person, at least two coils detect the frequency change if you have a metal or non-metallic tool, and only some of the frequency changes occur in case of a natural disaster such as an animal or heavy rain.

Therefore, by analyzing these changes, it is possible to determine whether it is a signal due to a natural disaster or a signal due to intrusion. Change can be classified as invasive or non-invasive by applying fuzzy theory.

On the other hand, the non-metal detection coil 610, the organism detection coil 620, and the metal detection coil 630 may each be accommodated in a metal rod, and these metal rods have a sensor as shown in FIG. 1, for example, an ultrasonic sensor. can be installed. The sensor may be managed by the control unit 460 of FIG. 2 by assigning a corresponding number to each metal rod. That is, by giving a sensor number and a metal rod number, it is possible to determine which sensor is attached to which metal rod.

In this state, the sensor transmits a signal to the adjacent metal rods, inputs the returned signal to the control unit 460 to process it, and as a result of the processing, for example, when the distance between the metal rods exceeds the reference distance, the metal rods are normal. It is judged that the position cannot be maintained and appropriate measures are taken.

[Fourth embodiment]

14 is a control configuration diagram of an intrusion detection system according to a fourth embodiment of the present invention.

In the fourth embodiment of the present invention, the CCTV 1000 is additionally configured in the intrusion detection system using the complex oscillation coil, and the intrusion detection signal using the complex oscillation coil and the intrusion detection signal using the CCTV 1000 are linked with each other to more accurately This was done to determine whether there was an intrusion.

The control unit 900 is provided with a program capable of analyzing the type of intrusion, speed, movement pattern, etc. by analyzing the video signal captured by the CCTV (1000).

In the fourth embodiment, by linking the CCTV 1000, the intrusion type, size, speed, etc. can be analyzed more accurately, and even if any one of them fails, there is no hindrance to intrusion detection.

Intrusion detection according to the fourth embodiment is performed as follows.

First, a frequency signal by the complex oscillation coils 610 , 620 , 630 is input to the controller 900 and processed.

In addition, the video signal by the CCTV (1000) is input to the control unit (900).

The control unit 900 compares the frequency signal by the composite oscillation coils 610, 620, and 630 with the video signal by the CCTV 1000 and analyzes whether the intrusion type, speed, and movement pattern match each other.

As a result of the analysis, if the intrusion type, speed, and movement pattern match each other, it is determined that they match and notifies the manager through the alarm unit.

On the other hand, if they do not match, the control unit 900 determines that the intrusion-related information analyzed by the video signal of the CCTV 1000 is more accurate, and the frequency signal by the complex oscillation coils 610, 620, 630 is that of the complex oscillation coil. It is judged to be inaccurate depending on the cause such as failure. Accordingly, the control unit 900 notifies the manager of the failure of the composite oscillation coil through an alarm unit.

In addition, when the video signal of the CCTV 1000 is unclear, that is, when a situation such as a cloudy picture is determined according to weather or field conditions, the control unit 900 notifies the manager through an alarm unit.

On the other hand, the non-metal detection coil 610, the organism detection coil 620, and the metal detection coil 630 may each be accommodated in a metal rod, and these metal rods have a sensor as shown in FIG. 1, for example, an ultrasonic sensor. can be installed. The sensor may be managed by the control unit by assigning a corresponding number to each metal rod. That is, by giving a sensor number and a metal rod number, it is possible to determine which sensor is attached to which metal rod.

In this state, the sensor sends a signal to the adjacent metal rods, inputs the returned signal to the control unit to process it, and as a result of the processing, for example, if the distance between the metal rods exceeds the reference distance, the metal rods maintain their normal position. It is judged that it cannot be done, and appropriate action is taken.

Also, a sensor may be attached to the CCTV 1000 . In this state, the sensor sends a signal toward the floor and inputs the returned signal to the control unit to process it. judges that it cannot maintain its normal position and takes appropriate action.

The control unit 900 analyzes the position signal and detection signal of the complex oscillation coil and CCTV at the same time, and connects the signals of the complex oscillation coil and the CCTV with each other only when the complex oscillation coil and the CCTV maintain a normal position to determine the type, speed and Analyze movement patterns.

In addition, when the complex oscillation coil or CCTV is not in a normal position, the intrusion type, speed, and movement pattern are analyzed based on the detection signals of other elements that are not in the normal position.

To explain this in more detail, if both the composite oscillation coil and CCTV are in normal positions, the two signals are compared to analyze the intrusion type, speed, and movement pattern. If the complex oscillation coil is in a normal position and the CCTV is not in a normal position, the intrusion type, speed and movement pattern are analyzed based on the detection signal of the complex oscillation coil. If the complex oscillation coil is not in a normal position and the CCTV is in a normal position, the intrusion type, speed, and movement pattern are analyzed based on the CCTV detection signal. If both the composite oscillation coil and CCTV are not in their normal positions, this fact is notified to the manager through the alarm unit.

On the other hand, when it is determined that the complex oscillation coil cannot maintain the normal operation, the image captured by the CCTV 1000 is analyzed as an intrusion of a person, whereas the approach of a bird or organism other than a person is detected. An example may be a case in which the composite oscillation coil senses a frequency signal.

In addition, the CCTV 1000 is a movable configuration, and since it is possible to shoot the surrounding area, if the control unit determines that the frequency detected by the complex oscillation coil is human intrusion while shooting the surrounding area, the control unit at this time By controlling the CCTV, it is possible to take pictures of the place where the composite oscillation coil is installed.

In this case, since the video signal by the CCTV is also analyzed as an intrusion by a person, it can be determined more reliably as an intrusion by a person. In other words, while shooting the surrounding area where the complex oscillation coil is installed, when a human intrusion is detected by the complex oscillation coil, the CCTV controls the situation (scene) so that the situation (scene) is captured by the CCTV to determine the intrusion of a person very efficiently. can

[Fifth embodiment]

15 is a networking configuration diagram of an intrusion detection system according to a fifth embodiment of the present invention. 16 is a configuration diagram of the control server of FIG. 15 .

In the present invention, for example, a terminal is networked to an intrusion detection device installed for each of a plurality of fences, so that the detection device can be controlled by the terminal, and a control center server capable of managing a plurality of fences is configured, and a plurality of It is configured to process intrusion detection information transmitted from a detection device or terminal.

For example, for intrusion management for a plurality of fences, the control center is networked with the intrusion detection device of each fence or networked with the terminal networked with the fence intrusion detection device to process the detection information transmitted from each detection device or terminal it can be done The networking refers to encompassing short-distance, long-distance, wired, wireless, and the like.

In order for the control center to be networked directly with the sensing device in addition to being networked with each terminal, it may be configured to communicate with the control server through a communication unit configured in the sensing device.

Therefore, if the network is configured in this way, even if the fence manager is at a remote location, he can receive information received from the control server to check whether an intrusion into the fence has occurred, and take appropriate measures.

As shown in FIG. 15, in the fifth embodiment of the present invention, an intrusion detection device 1 is installed on a fence, and the detection device 1 is networked to a terminal or control server 4 through an Internet network N. can be

When the signal sensed by the sensing device 1 is transmitted to the terminal or the control center 4, an appropriate action is taken according to the processing result of the terminal or control server 4 that has processed it.

In the above, the sensing device 1 may be networked with only one element of the terminal or the control server 4 . That is, it can be seen that the terminal or the control center 4 performs the same operation as the control operation for intrusion detection.

In an embodiment of the present invention, the control server 4 is networked with a plurality of terminals or sensing devices 1, so that multiple fences can be conveniently and collectively managed, for example, an intrusion into one of the fences When detected, this information is stored in the database 41, and when an intrusion occurs in another fence, it can be determined whether it is the same intrusion type, thereby enabling more reliable detection.

With this configuration, even if the fence manager is in a remote location, it is possible to easily check whether an intrusion has occurred by the control server 4 receiving the detection information from the detection device 1, and appropriate measures can be taken.

When an intruder A occurs in the first fence, the control server 3 stores information related to the intruder A, for example, information related to intrusion time, intrusion method, intrusion passage, intrusion type, intrusion speed, intrusion size, etc. to the second , and the third, etc. are shared with the manager terminal that manages the fence.

The control configuration of the terminal or control server 4 is described in detail through the control block diagram of FIG. 16 as follows.

The control server 4 is configured to include a control unit 41 , an alarm driving app 42 , a communication unit 43 , and an alarm unit 44 .

When a detection signal is received from the detection device 1 through the communication unit 43 , the control unit 41 transmits it to the alarm driving app 42 .

The alarm driving app 42 includes an intrusion type, size, and speed determination module 42-3 that determines the type of intrusion based on the detection signal input from the control unit 41, and the intrusion type, size, and speed determination module ( An alarm setting module 42-2 that selects an alarm already set according to the signal determined through 42-3), and an alarm execution that outputs an alarm selected through the alarm setting module 42-2 to the alarm unit 44 module 42-1.

In the above, the intrusion type, size, and speed determination module 42-3 is, for example, when the detected intruder's intrusion reaches the entrance of the fence, when it enters through the fence, whether the intruding object is a person or a specific object, etc. This can be.

That is, it can be set to generate different alarms for each type of determination. However, it is not necessarily limited to only these types. In addition, there may be an intrusion rate and the size of an intruding object or person.

The alarm unit 44 is set to, for example, a siren sound, a trumpet sound, a flute sound, etc. various alarms according to the type, size and speed of intrusion, and the administrator is aware of this in advance.

It can also trigger an alarm on the type, size and speed of intrusion by emitting an alarm sound several times in succession.

On the other hand, the terminal may have the same configuration as the control server (4). In this case, the operation of the control server 4 may be performed in the same manner in the terminal.

An intruder detection operation of the present invention configured as described above will be described.

First, the control server 4 runs the alarm driving app (42).

When the alarm driving app 42 is executed in the control server 4, the control server 4 is in a state capable of, for example, short-distance or long-distance wireless communication with the sensing device 1 .

In this state, if an intruder occurs in the fence in which the detection device 1 is installed, it is detected by the detection device 1 .

The signal detected by the sensing device 1 is transmitted to the control server 4 .

The sensing signal transmitted from the sensing device 1 is received by the control unit 41 through the communication unit 44 of the control server 4 .

The control unit 41 transmits the received detection signal to the alarm driving app 42 .

The alarm driving app 42 determines the detection signal input from the control unit 41 through the intrusion type, size, and speed determination module 42-3, and an alarm already set through the alarm setting module 42-2 is selected, and the alarm selected through the alarm execution module 42-1 is outputted through the alarm unit 44 .

An embodiment for realizing the intrusion detection system using the composite oscillation coil of the present invention has been described. The embodiments described above are illustrative of some of the many specific embodiments that represent the principles described herein. Accordingly, by using the embodiments of the present invention, those skilled in the art will be able to easily implement many different methods within the scope defined by the claims of the present invention.
