도 4는 본 발명의 일실시예에 따른 외곽 침입 감지 시스템의 복합펜스감지부에서 침입탐지를 수행하는 것을 설명하기 위한 도면이다.4 is a view for explaining the intrusion detection in the composite fence detection unit of the outer intrusion detection system according to an embodiment of the present invention.
도 4를 참조하면, 3축 가속도센서(11), PIR 센서(12) 및 쌍안정 레이더(13)를 포함하는 복합펜스감지부(10)는 펜스 면마다 설치된다. 보통 펜스 면은 2 ~ 5m 정도의 넓이이다. 복합펜서감지부(10)가 아닌 다른 종류의 침입탐지센서들과 함께 설치될 경우에는 펜스센서의 민감도를 높게 하는 것이 가능하기 때문에 펜스 면보다 넓은 간격으로 설치하는 것이 가능하다.Referring to FIG. 4, the composite fence detecting unit 10 including the three-axis acceleration sensor 11, the PIR sensor 12, and the bistable radar 13 is installed for each fence surface. The fence side is usually about 2 to 5 meters wide. When installed together with other types of intrusion detection sensors other than the composite fence detection unit 10, it is possible to increase the sensitivity of the fence sensor, it is possible to install at a wider interval than the fence surface.
각 복합펜스감지부(10A,10B,10C)는 케이블로 연결이 되며, 케이블 안에는 통신을 하기 위한 2가닥의 통신선과 전력을 공급하기 위한 2가닥의 전선들이 들어 있다. 이러한 케이블들은 커넥터를 사용하여 각 복합펜스감지부(10A,10B,10C)에 연결된다. 케이블을 사용하여 연결되는 복합펜스감지부(10A,10B,10C)들은 선형으로 연결된다. 선형으로 연결되어 있는 복합펜스감지부(10A,10B,10C)들의 한쪽 끝 지점에 있는 마지막 복합펜스감지부(10)는 감지부 컨트롤러(20)에 연결된다. 마지막 복합펜스감지부(10)와 감지부 컨트롤러(20)의 연결도 복합펜스감지부(10)들 간에 연결하는 케이블과 동일한 케이블을 사용하여 연결된다. 예를 들면, 하나의 감지부 컨트롤러(20)에는 최대 220개의 복합펜스감지부(10)가 연결될 수 있다.Each compound fence detecting unit (10A, 10B, 10C) is connected by a cable, the cable contains two wires for communication and two wires for supplying power. These cables are connected to each composite fence detecting unit 10A, 10B, 10C using a connector. The composite fence detecting units 10A, 10B, and 10C connected by using a cable are linearly connected. The last compound fence detection unit 10 at one end of the compound fence detection units 10A, 10B, and 10C connected in a linear manner is connected to the detection unit controller 20. Finally, the connection between the composite fence detection unit 10 and the detection unit controller 20 is also connected using the same cable as the cable connecting the composite fence detection unit 10. For example, up to 220 composite fence sensing units 10 may be connected to one sensor controller 20.
3축 가속도센서(11), PIR 센서(12) 및 쌍안정 레이더(13)를 포함하는 복합펜스감지부(10)의 동작원리는 다음과 같다.The operation principle of the composite fence detecting unit 10 including the three-axis acceleration sensor 11, PIR sensor 12 and bistable radar 13 is as follows.
평상시에는 저전력으로 동작하는 트리거 센서인 3축 가속도센서(11)와 PIR 센서(12)만이 동작을 한다. 침입자가 펜스를 넘거나 뚫어서 펜스 내부에 있는 시설로 침입을 시도할 경우에 침입자가 펜스에 접근하게 되고 이 경우 침입자의 체온에 의하여 적외선의 변화가 발생하기 때문에 PIR 센서(12)에 의하여 먼저 탐지가 된다.Normally, only the 3-axis acceleration sensor 11 and the PIR sensor 12, which are trigger sensors operating at low power, operate. When an intruder attempts to intrude into a facility inside the fence by crossing or penetrating the fence, the intruder approaches the fence. In this case, the infrared ray is changed by the body temperature of the intruder. do.
도 2에 나타낸 바와 같이, PIR 센서(12)는 펜스 전방을 바라보고 있다. 침입자가 펜스에 접촉을 하여 진동이 발생하게 되면 이를 3축 가속도센서(11)가 탐지한다.As shown in FIG. 2, the PIR sensor 12 faces the fence front. When an intruder makes contact with the fence and vibrates, it detects the 3-axis acceleration sensor 11.
보통은 PIR 센서(12)가 먼저 침입을 감지하지만, 침입자가 원거리에서 도구를 사용하여 펜스에 접촉을 할 경우에는 3축 가속도센서(11)가 먼저 침입을 탐지할 수 있다. 트리거센서(3축 가속도센서(11) 또는 PIR 센서(12))가 침입을 탐지하게 되면 고성능센서인 쌍안정 레이더(13)를 활성화 시켜서 보다 정밀하게 침입을 탐지하게 된다.Normally, the PIR sensor 12 first detects an intrusion, but when the intruder contacts the fence using a tool from a distance, the three-axis acceleration sensor 11 may first detect the intrusion. When the trigger sensor (three-axis acceleration sensor 11 or PIR sensor 12) detects the intrusion to activate the bi-stable radar 13, which is a high performance sensor to detect the intrusion more precisely.
이하에서는 보다 구체적인 복합펜스감지부(10)의 동작원리를 설명한다.Hereinafter, the operation principle of the composite fence detection unit 10 in more detail.
복합펜스감지부(10B)가 담당하는 구역으로 침입자가 접근을 할 경우 복합펜스감지부(10B)의 트리거센서가 먼저 탐지를 하게 된다. 이러한 경우 복합펜스감지부(10B)의 트리거센서는 복합펜스감지부(10B)의 고성능센서인 쌍안정 레이더(13B)를 활성화시킨다. 복합펜스감지부(10B)의 쌍안정 레이더(13B)는 자신의 좌측 및 우측에 있는 펜스센서인 복합펜스감지부(10A) 및 복합펜스감지부(10C)의 쌍안정 레이더(13A,13C)에게 교대로 RF 신호를 전송할 것을 요청한다. 이렇게 하는 이유는 복합펜스감지부(10B)를 중심으로 좌측 혹은 우측에서 침입이 발생할 수 있기 때문이다.When the intruder approaches the area in charge of the composite fence detection unit 10B, the trigger sensor of the composite fence detection unit 10B detects first. In this case, the trigger sensor of the compound fence detection unit 10B activates the bistable radar 13B, which is a high performance sensor of the compound fence detection unit 10B. The bistable radar 13B of the composite fence detection unit 10B is provided to the bistable radar 13A and 13C of the composite fence detection unit 10A and the composite fence detection unit 10C, which are fence sensors on its left and right sides. Alternately requests the transmission of an RF signal. The reason for doing this is that intrusion may occur in the left or right side of the composite fence detecting unit 10B.
협력을 요청받은 복합펜스감지부는 협력을 요청한 복합펜스감지부에게 메시지를 보내기 위하여 자신의 RF 안테나를 사용하여 전파를 전송한다. 협력을 요청한 복합펜스감지부는 자신의 RF 안테나를 통하여 수신되는 전파의 신호 파형을 분석하여 침입 여부를 판별할 수 있다.The composite fence detection unit requested for cooperation transmits a radio wave using its RF antenna to send a message to the composite fence detection unit requesting cooperation. The composite fence detection unit requesting cooperation may determine whether an intrusion is made by analyzing a signal waveform of a radio wave received through its RF antenna.
이와 같이 침입을 탐지한 복합펜스감지부와 침입을 탐지한 복합펜스감지부의 좌우 양측에 있는 복합펜스감지부들과의 협력에 의하여 최종적으로 침입이 발생하였는지 최종적으로 결정하게 되면, 3축 가속도센서들(침입을 탐지한 복합펜스감지부 및 좌우 양측에 있는 2개의 복합펜스감지부)의 탐지결과, 먼저 침입을 탐지한 복합펜스감지부의 쌍안정 레이더 탐지결과들을 모두 종합하여 침입의 종류와 침입이 발생한 위치를 최종적으로 판정하게 된다.When the final determination of the intrusion occurred by the cooperation of the composite fence detection unit detecting the intrusion and the composite fence detection units on the left and right sides of the detection of the intrusion, the three-axis acceleration sensors ( Type of intrusion and location where intrusion occurred by combining the detection results of the compound fence detection unit detecting the intrusion and the two compound fence detection units on both the left and right sides, and the bistable radar detection results of the compound fence detection unit detecting the intrusion first. Will finally be determined.
침입에 의하여 발생하는 경보의 종류에는 침입자가 펜스를 향해 접근하고 있거나 펜스 앞에서 서성이고 있는 펜스 접근 경보와 펜스 접촉에 의하여 발생하는 펜스 침입 경보가 있다.There are two types of alarms that are caused by intrusions: fence access alarms that are intruder approaching or standing in front of the fence and fence intrusion alarms that are caused by fence contact.
일반적으로 PIR 센서 및 쌍안정 레이더에 의해서만 탐지가 되었을 경우 펜스 접근 경보를 발생한다.Generally, a fence approach alarm is triggered when detected only by the PIR sensor and bistable radar.
한편, PIR 센서, 쌍안정 레이더 및 3축 가속도 센서 모두에 의하여 탐지가 되었을 경우 펜스 침입 경보를 발생한다.On the other hand, when detected by both the PIR sensor, bistable radar and the 3-axis acceleration sensor generates a fence intrusion alarm.
이상과 같이, 본 발명의 실시예에 따른 외곽 침입 감지 시스템은 침입자의 침입을 직접 감지하는 직접식 센서인 3축가속도센서와, 침입자의 침입을 간접 감지하는 간접식 센서인 PIR 센서 및 쌍안정 레이더를 함께 사용하는 복합 방식의 외곽 침입 감지 시스템을 구성함으로써 펜스 주변의 침입자를 보다 효과적이고 신뢰성 있게 감지할 수 있다.As described above, the outer intrusion detection system according to an embodiment of the present invention is a three-axis acceleration sensor that is a direct sensor that directly detects the intruder, PIR sensor and bi-stable radar, which is an indirect sensor that indirectly detects the intruder By constructing a complex outer intrusion detection system that uses a combination of the two, it is possible to detect intruders around the fence more effectively and reliably.
따라서, 본 발명의 실시예에 따른 외곽 침입 감지 시스템은 높은 보안등급을 요하는 군시설, 발전소, 공항, 물류센터 등 중요 시설물에 대한 최고 수준의 경계 성능을 제공할 수 있다. 또한, 패턴인식 기술을 이용한 노이즈 필터링 기능을 제공함으로써 그동안 외곽 침입 감지 시스템의 주요 문제점이었던 오경보 문제를 획기적으로 줄여 침입 감지 신뢰성을 높일 수 있다. 또한, 펜스로 접근하는 표적을 사전에 탐지 가능하고, 펜스 상단 월책 탐지(비접촉 월책 포함)가 가능하며, 비가시 환경에서의 탐지 제한을 최소화할 수 있다.Therefore, the outer intrusion detection system according to the embodiment of the present invention can provide the highest level of boundary performance for important facilities such as military facilities, power plants, airports, and distribution centers that require a high security level. In addition, by providing a noise filtering function using a pattern recognition technology, it is possible to significantly increase the intrusion detection reliability by drastically reducing the false alarm problem, which has been the main problem of the outer intrusion detection system.
