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

1 is a block diagram of the 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 are the receiving unit 110 and the standard time setting unit 120 , The control unit 130 and the output unit 140.

More specifically, the receiver 110 is provided with a plurality of ports to receive each first detection signal from at least two or more homogeneous or heterogeneous detectors through the respective ports.

For example, as shown in (a) of FIG. 2, the receiving unit 110 includes a sensing transmitter TX configured with an A group detector, a B detector, and a C group detector, A group detector, B detector, and C group. When the sensing receiver RX configured with the detector is configured and the control board 100 of the present invention is configured in the sensing transmitter TX, when it is detected by A, A` group sensor, when it is detected by B, B` detector , C, C` A plurality of ports 111 are provided for each of the first sensing signals sensed by any one or a combination of the group detectors as shown in (b) of FIG. Receives a detection signal detected at the detection signal detected at C, C`, a detection signal detected at B, B`.

That is, the receiver 110 receives a first detection signal detected by each homogeneous or heterogeneous detector, sets a scenario for preventing false detection by using each received first detection signal, and controls through the set scenario. To generate a signal.

On the other hand, the receiving unit 110 may be configured as a sensing transmission unit (TX), the detection receiving unit (RX) shown in Figure 2, as shown in Figure 3, the control board 100 of the present invention in any place It can be configured in the A-detector in the access road, the B-detector in the door and the C-detector in the interior space, and at this time, the receiver 110 is provided with a plurality of ports 111 A-detector, B-detector, C It is also desirable to receive each first sensing signal from the detector.

The standard time setting unit 120 sets a standard time to each first sensing signal received at each port.

For example, as shown in FIG. 4, if the sensor A senses the area a and the sensor B senses the area b, as illustrated in FIG. 4, the standard time setting unit 120 detects the area B after a predetermined time after being detected by the sensor A. This should be detected in order to prevent a false positive because the intrusion is logically correct.

Therefore, the standard time setting unit 120 is to set a standard time for each first detection signal detected by the detectors to logically set the scenario corresponding to the intrusion, and to set the scenario corresponding to the intrusion based on this. .

The controller 130 may generate a scenario based on one or a combination of and, or, group, and group or with respect to each of the first sensing signals for which the standard time is set, and time information of each of the first sensing signals. And an algorithm for generating a control signal according to the set scenario.

First, in the case of and combination, as illustrated in FIG. 5, it is assumed that A detection signal is generated in A sensor, B detection signal in B sensor, and C detection signal in C sensor, and intrusion is detected in a special environment. In order to set the scenario to generate a control signal when all of the A detector, the B detector, and the C detector are detected within 3, the A sense signal, the B sense signal, and the C sense signal received at each port 111 of the receiver 110. Is to set and to.

That is, it is set as shown in [Equation 1].

[Vertical 1]

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

As a result, the control signal is a detection signal A, B detection signal, C detection signal must be received at the port 111 of the receiving unit 110, the control signal is output to detect the intrusion A detection signal, B detection signal, C If any one of the detection signals are not received at any of the ports of the receiver 110, the control signal is not output so as to prevent false positives.

Next, in the case of or combination is a special environment, for example, the intruder crawls to avoid the A, B detector as shown in Figure 5, or invasion using a jump or a tool to avoid the B, C detector, etc. If a scenario is set to generate a control signal when any one of A sensor, B sensor, and C sensor is detected in a condition of intrusion, A detection signal, B received at each port 111 of the receiver 110, It is to set the detection signal and C detection signal by or combination.

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

[Formula 2]

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

As a result, when any one of the A detection signal, the B detection signal, and the C detection signal is received at the port 111 of the receiver 110, the control signal is output to detect the intrusion, and the A detection signal and the B detection signal. If all of the C detection signals are not received at the port 111 of the receiving unit 110, the control signal is not outputted to prevent false detection.

Next, the control unit 130 in the case of and and or combination, for example, A, B detector shown in Figure 5 is a space detector and C detector is configured as a line detector for the purpose of human intrusion at the entrance of the farm When the animal is invaded, the C detection signal is generated in the C sensor by the height of the animal, but the A and B detection signals are not generated in the A and B sensors.

Therefore, the C sensor generates a C detection signal by means of a key, and according to the height of a person, the A detector and the B detector may set a scenario in which one of the A detection signal and the B detection signal should be generated. A sensed signal, B sensed signal, and C sensed signal received at 111) are set in combination with and.

That is, it is set as [vertical 3].

[Vertical 3]

A sense signal or B sense signal and C sense signal = control signal output

As a result, the control signal is any one of the A detection signal, B detection signal is received at the port 111 of the receiving unit 110, when the C detection signal is received, the control signal is output to detect the intrusion and only the C detection signal receiving unit ( When received at the port 111 of the 110, the control signal is not outputted to prevent false positives.

On the other hand, in addition to [Equation 3] it is also preferable to set the new form by combining and and or in accordance with the number of the detection signal.

Next, the controller 130 will be described with respect to the group and combination, group or combination, group and and group or combination, and, or, group and, group or combination.

First, in the case of group and, as shown in FIG. 6, in the group A detector including the A1 detector and the A2 detector, the A1 detection signal and the A2 detection signal are generated and the B group including the B1 detector and the B2 detector. Suppose that the detector generates B1 and B2 detection signals, A1 and B1 are space detectors, while A2 and B2 detectors are line detectors. , B1 and B2 detection signals are set in group and combination.

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, while the A1 and A2 detection signals are received at the respective ports 111 of the receiver 110, the B1 and B2 detection signals must be received to output a control signal to detect the intrusion.

Next, the case of group or will be described. As shown in FIG. 6, the A group detector and the B group detector are set to a group or a combination of the A1, A2, B1, and B2 detection signals as 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, A2 detection signal is received at the port 111 of the receiving unit 110 or any one of the B1, B2 detection signal is received at the port 111 of the receiving unit 110, the control signal is output and invaded. Detect.

As described above, the controller 130 may not only set a scenario in a group and and a group or a combination, but also set a scenario by combining the group and and a group or with each other.

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

For example, as illustrated in FIG. 7, the A-group sensor including the A1 and A2 detectors generates the A1 detection signal and the A2 detection signal, the B detection signal is generated from the B detector, and the C detection signal is generated from the C detector. Suppose that a D1 detector signal and a D2 detector signal are generated from a D group detector including a detector and a D2 detector, and the scenario is set to a group and a group or a combination according to the 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

[Equation 6] is only applied to the environment, it is preferable to set the scenario by applying other and, or, group and, group or in addition to the above [Equation 6] according to different environments.

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

In addition, the controller 130, after receiving a certain number of each of the first detection signal set the standard time of each of the received first detection signal, after receiving the second detection signal for detecting the first area In the same manner as the third detection signal for detecting the second area belonging to the first area within a predetermined time is received, and then the fourth detection signal for detecting the third area belonging to the second area is received again within a predetermined time. Preferably, the algorithm further includes generating a control signal when a predetermined number of times of the first detection signal is set.

For example, when two first sensing signals for which the standard time is set are received, one of the two first sensing signals includes a first sensing signal for sensing region A by a spatial sensor as shown in FIG. 8. When the second detection signal is generated and detects the area B by the line detector, the controller 130 detects the intrusion in the area A and receives the intrusion in the area B after a predetermined time after the first detection signal is received. When detected and the second detection signal is received logically corresponds to the intrusion is to generate a control signal.

In addition, when three or more of the same or different types of detectors are preferably implemented in the same manner as described above.

Further, the control unit 130 prioritizes each of the received first sensing signals, and when the first sensing signal having at least two or more upper priorities is not received, the first sensing signal having the lower priority is received. Preferably, an algorithm is further included to block the control signal when received.

For example, referring to FIG. 9, when the A detector is configured at the entrance, the B detector is configured at the entrance, and the C detector is configured at the room, the A detector signal detected by the A detector is placed at the highest priority and detected by the B detector. When the detected B detection signal is set as the next priority and the C detection signal detected by the C detector is configured as the last priority, the A, B, C, and A, B, and C detectors sequentially detect the intrusion from the entrance to the room. Receiving the C detection signal at the receiver 110 may determine that an intruder has intruded.

However, since the detection unit 110 generates the C detection signal from the C detector and receives the reception unit 110 even though the A and B detectors do not detect the upper priority, the control signal for the C detection signal is blocked. It is.

In addition, the control unit 130 may further include an algorithm for generating a control signal when at least two first sensing signals are simultaneously detected in a plurality of ports at the time of receiving the respective first sensing signals.

For example, as illustrated in FIG. 10, when sensor A detects region a and sensor B detects region b, only sensor A is detected to determine that it senses the same as an animal, and overlaps each other among regions a and b. If detected simultaneously in the area is to determine the intrusion.

As a result, according to the present invention, the A detection signal detecting the a area and the B detection signal detecting the b area are detected within a set time in the plurality of ports 111 of the receiver 110 in the overlapped areas of the a and b areas. It is determined that an intrusion has been made, and a control signal is generated and the surveillance camera is rotated and monitored in the direction of detecting the intruder.

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 sensing area direction detected by the homogeneous or heterogeneous detector which transmitted the first sensing signal.

As a result, when the control signal detects the intrusion by the combination of and, or, group and, group or the first detection signal received by the receiver 110, the surveillance camera for monitoring the intruder is switched to the intruder direction. Under control, the surveillance camera functions to photograph the intruder.

In addition, the control signal is controlled to transmit the warning sound or warning information to the manager terminal.

That is, the control signal provides an alarm sound or an alarm information to the manager terminal to immediately respond to each first detection signal received by the receiver 110 in a combination of and, or, group and, group or, etc. It is.

As described above, the present invention is disclosed in the drawings and the detailed description of the preferred embodiments, the specific terms used above are merely used for the purpose of illustrating the invention, the meaning of the invention described in the claims or claims It is not used to limit the scope.
