Best Mode for Carrying Out the Invention Hereinafter, a configuration and an operation of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of an intrusion detection control board using a plurality of detectors according to an embodiment of the present invention. The intrusion detection control board 100 using the plurality of detectors includes a receiving unit 110, a standard time setting unit 120, A control unit 130, and an output unit 140.

In more detail, the receiving unit 110 includes a plurality of ports, and receives each first sensing signal detected from at least two or more identical or heterogeneous sensors through the respective ports.

For example, as shown in (a) of FIG. 2, the receiving unit 110 may include an A group detector, a B detector, a detection transmitting unit TX configured with a C group detector, an A group detector, a B detector, When the detection receiver RX configured with the detector is configured and the control board 100 of the present invention is configured in the detection transmission unit TX, when it is detected by A, A` group winding, when it is detected by the B, B` detector , C, and C` group detectors, a plurality of ports 111 are provided as shown in (b) of FIG. 2 to detect each of the first detection signals, The sensing signal detected at B, B`, and the sensing signal sensed at C, C`.

That is, the receiving unit 110 receives a first sensing signal sensed by each of the same or different types of sensors, sets a scenario for preventing a false alarm by using each of the first sensing signals received, Signal.

3, the control unit 100 may be connected to an arbitrary place (not shown). The control unit 100 may be connected to the control unit 100, A B sensor in a doorway, and a C sensor in an indoor space. In this case, the receiving unit 110 includes a plurality of ports 111 to detect the A sensor, the B sensor, the C sensor, It is also desirable to receive each first sense signal from the detector.

The standard time setting unit 120 sets a standard time for each of the first sensing signals received at the respective ports.

For example, as shown in FIG. 4, the standard time setting unit 120 may be configured such that the A sensor senses the area a and the B sensor senses the area b, It is logically intrusive to be able to prevent the occurrence of false positives.

Accordingly, the standard time setting unit 120 sets a standard time for each first detection signal detected by the detectors in order to logically set a scenario corresponding to the intrusion, and sets a scenario corresponding to the intrusion based on the standard time .

The control unit 130 may determine whether or not the first sensing signal having the standard time has been set by using any one or combination of and, or, group, and group, and the time information of each of the first sensing signals, And an algorithm for generating a control signal according to the set scenarios.

5, it is assumed that the A sensor generates the A sensing signal, the B sensor senses the B sensing signal, and the C sensor generates the C sensing signal as shown in FIG. 5, and detects the intrusion in a special environment If the scenario is set to generate a control signal if all of the A, B, and C detectors are detected within 3 ms, the A detect signal, B detect signal, C detect signal And a combination thereof.

That is, it is set as in [Expression 1].

[Equation 1]

A detection signal and B detection signal and C detection signal = control signal output

As a result, the control signal is a control signal that is received when the A, B, and C sensing signals are received at the port 111 of the receiving unit 110 to detect the intrusion, and the A sensing signal, the B sensing signal, When any one of the detection signals is not received at any one of the ports of the receiving unit 110, the control signal is not outputted, thereby preventing false alarms.

In the case of the following combinations, there is a special environment, for example, an intruder can use a variety of methods, such as crawling to avoid the A and B detectors as shown in FIG. 5, If a scenario is set up to generate a control signal when any one of the A sensor, the B sensor and the C sensor is detected in the case of attempting intrusion under the condition, the A sensing signal received at each port 111 of the receiving unit 110, B The detection signal, and the C detection signal.

 That is, it is set as shown in [Equation 2].

[Equation 2]

A detection signal or B detection signal or C detection signal = control signal output

If the control signal is received at the port 111 of the receiving unit 110, the control signal is output to detect the intrusion, and the A signal, the B signal, And C detection signals are not received at the port 111 of the receiving unit 110, the control signal is not output, thereby preventing false alarms.

5, the A and B detectors are space sensors, and the C sensor is a line sensor for the purpose of invading people at the entrance of a farm. In this case, when the animal enters, the C sensor generates a C sensor signal by the height of the animal, but the A and B sensors do not generate the A and B sensor signals, which is a scenario in which a human is not judged to be an intrusion.

Accordingly, the C sensor necessarily generates the C sensing signal, and according to the human key, the A sensor and the B sensor can set a scenario in which one of the A sensing signal and the B sensing signal is generated, 111, 111, 112, 113, 114, and 111, respectively.

That is, it is set as shown in [Equation 3].

[Equation 3]

{A sense signal or B sense signal} and C Sensing signal = Control signal output

As a result, when the control signal is received by the port 111 of the receiving unit 110 and the C sensing signal is received, one of the A sensing signal and the B sensing signal is output to detect the intrusion, 110, the control signal is not outputted, thereby preventing false alarms.

In addition to the above-mentioned [Equation 3], it is also preferable to combine and and or according to the number of sense signals to set them in a new form.

Next, the control unit 130 will describe the group and combination, group or combination, group and combination, and or, group, and combination.

First, as shown in Fig. 6, an A group sensor including an A1 sensor and an A2 sensor generates an A1 detection signal, an A2 detection signal, and a B group including a B1 sensor and a B2 sensor It is assumed that A1 and B1 detectors are spatial detectors and A2 and B2 detectors are spatially detectable when they are line detectors and A1 and A2 , B1, and B2 sensing signals in groups and combinations.

That is, it is set as shown in [Equation 4].

[Equation 4]

{A1 detection signal and A2 detection signal} and {B1 detection signal and B2 detection signal} = control signal output

As a result, when the A1 and A2 sensing signals are received at the respective ports 111 of the receiving unit 110, the B1 and B2 sensing signals must be received before the control signals are output to detect the intrusion.

Next, in the case of the group or, as shown in FIG. 6, the A group detector and the B group detector are set as a group or a combination of the A1, A2, B1, and B2 detection signals in a group in a special environment.

That is, it is set as shown in [Equation 5].

{A1 detection signal or A2 detection signal} or {B1 detection signal or B2 detection signal} = Control signal output

As a result, when any one of the A1 and A2 sensing signals is received at the port 111 of the receiving unit 110 or one of the B1 and B2 sensing signals is received at the port 111 of the receiving unit 110, Lt; / RTI >

As described above, it is preferable that the control unit 130 not only set the scenario in group and group or combination, but also set the scenario by combining group and group or.

Furthermore, it is also desirable to set scenarios in combination with and, or, group and, or.

For example, as shown in FIG. 7, an A group sensor including an A1 sensor and an A2 sensor generates an A1 detection signal, an A2 detection signal, a B sensor generates a B detection signal, a C sensor generates a C detection signal, Assuming that the D group detector including the detector and the D2 sensor generates the D1 detection signal and the D2 detection signal, the scenario is set in group and group or combination according to environment.

That is, it is set as shown in [Equation 6].

[Equation 6]

{A1 detection signal and A2 detection signal} or {B detection signal and C detection signal} or {D1 detection signal or D2 detection signal} = control signal output

It is preferable to set the scenario by applying another group, or, group, and group or, in addition to the above-mentioned [Equation 6], according to the different environment.

In addition, all the scenarios described above are preferably set to include time information.

In addition, when a predetermined number of the first sensing signals having the standard time among the received first sensing signals are received, the controller 130 receives a second sensing signal, which senses the first sensing area, The fourth sensing signal is received in a manner such that a third sensing signal sensing a second area belonging to the first area is received within a predetermined time and then a fourth sensing signal sensed within a predetermined time and belonging to the second area is received, And an algorithm for generating a control signal when the predetermined number of times of the first sensing signals is repeated.

For example, when two first sensing signals having the standard time are received, one of the two first sensing signals is a first sensing signal for sensing the A region by the spatial sensor as shown in FIG. 8 When the second sensing signal is generated by the line sensor, the controller 130 detects intrusion in the area A and detects intrusion in the area B after a predetermined time after the first sensing signal is received. And when the second sensing signal is received, it corresponds to the logically intrusion and thus generates a control signal.

Also, it is preferable that the same type or three or more heterogeneous detectors are implemented in the same manner as described above.

In addition, when the first sensing signal having a higher priority than at least two higher priority signals is not received, the first sensing signal having a lower priority is assigned to the first sensing signal, It is preferable to further include an algorithm for blocking the control signal when it is received.

For example, referring to FIG. 9, when the A sensor is configured in the access road, the B sensor is configured at the entrance, and the C sensor is configured in the room, the A sensor signal detected at the A sensor is given the highest priority, A, B, and C detectors A, B, and C detect a sequence of A, B, and C detectors in the process of entering the room from the entryway when the C sensing signal detected by the C sensor is configured as the last priority, C detection signal from the receiving unit 110 can be determined to be an intruder.

However, even if the A and B detectors in the higher priority do not detect the C sensor, the C sensor generates a C sensor signal and the receiving unit 110 receives a false signal. Therefore, the control signal for the C sensor signal is interrupted .

The controller 130 may further include an algorithm for generating a control signal when at least two or more first sensing signals are simultaneously detected within a predetermined time in a plurality of ports at the time of receiving the first sensing signals.

For example, as shown in FIG. 10, when the A sensor senses the area a and the B sensor senses the area b, only the A sensor is sensed to judge that the animal is sensed. In the case of simultaneous detection in the area, it is judged as an intrusion.

That is, the detection signals A and B of the plurality of ports 111 of the receiving unit 110 are detected within a predetermined time period, It determines that an intrusion has been made and generates a control signal, and the surveillance camera rotates in the direction in which the intruder is detected and monitors it.

The output unit 140 transmits the control signal to the surveillance camera.

That is, the control signal controls the at least one surveillance camera to switch to the direction of the sensing area detected by a homogeneous or heterogeneous sensor transmitting the first sensing signal.

 If the control signal detects the intrusion of each of the first detection signals received by the receiving unit 110 in combination of and, or, group and group, or the like, the surveillance camera for monitoring the intruder is switched to the intruder direction The surveillance camera acts to shoot an intruder.

In addition, the control signal controls the warning sound or the warning information to be transmitted to the administrator terminal.

That is, the control signal provides a warning sound or alarm information to the administrator terminal in order to promptly respond to each intrusion detected by a combination of the first, second, and third detection signals received by the receiver 110 .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It is not used to limit the scope.

Therefore, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
