As shown in FIG. 1, the digital transceiver 210, the sink node 220, the lightning rod 230, and the surveillance camera 240 may be implemented. ) And a power supply unit 250.
이하에서는, 도 2를 참조하여 산불 감시 시스템 전체에 대해 상세히 설명한다. 도 2에는 도시와 설명의 편의를 위해, 하나의 중계장치만을 참조부호 "200"으로 나타내었다. 또한, 도 2에는, 산불 감시 시스템의 하위 계층에 해당하는 무선 센서 네트워크를 구성하는 무선 센서 노드들(300-1 내지 300-6)과 현장 관리자가 이용하는 휴대 단말기(400)를 더 도시하였다.Hereinafter, the entire forest fire monitoring system will be described in detail with reference to FIG. 2. In FIG. 2, for convenience of illustration and description, only one relay device is denoted by reference numeral 200. In addition, FIG. 2 further illustrates the wireless sensor nodes 300-1 to 300-6 and the portable terminal 400 used by the field manager constituting the wireless sensor network corresponding to the lower layer of the forest fire monitoring system.
무선 센서 노드들(300-1 내지 300-6)로 구성되는 무선 센서 네트워크는 산불을 감시할 산의 지형과 환경에 맞는 토폴로지로 설계된다. 도 3에는, 도 2에 도시된 무선 센서 노드들(300-1 내지 300-6)의 세부구성을 하나의 참조부호 "300"으로 대표하여 도시하였다.The wireless sensor network composed of the wireless sensor nodes 300-1 to 300-6 is designed in a topology suitable for the terrain and environment of a mountain to monitor forest fires. In FIG. 3, the detailed configuration of the wireless sensor nodes 300-1 to 300-6 shown in FIG. 2 is represented by one reference numeral 300.
도 3에 도시된 바와 같이, 무선 센서 노드(300)는 온도 센서(310), 습도 센서(320), 이산화탄소 센서(330) 및 지그비 모듈(340)을 구비한다.As shown in FIG. 3, the wireless sensor node 300 includes a temperature sensor 310, a humidity sensor 320, a carbon dioxide sensor 330, and a Zigbee module 340.
온도 센서(310)의 센싱에 의해 생성된 온도 정보, 습도 센서(320)의 센싱에 의해 생성된 습도 정보 및 이산화탄소 센서(330)의 센싱에 의해 생성된 이산화탄소 농도 정보는 지그비 모듈(340)에 의해 중계장치(200)의 싱크 노드(220)로 전송된다.Temperature information generated by the sensing of the temperature sensor 310, humidity information generated by the sensing of the humidity sensor 320 and carbon dioxide concentration information generated by the sensing of the carbon dioxide sensor 330 by the Zigbee module 340 It is transmitted to the sink node 220 of the relay device 200.
한편, 지그비 모듈(340)은 습도 센서(320)의 센싱에 의해 생성된 습도 정보로부터 실효 습도를 계산하고, 산출된 실효 습도에 따라 무선 센서 노드(300)의 동작 간격을 제어할 수 있다. 여기서, 무선 센서 노드(300)의 동작은, 센서들(310, 320 및 330)에 의한 센싱 동작과 지그비 모듈(340)에 의한 전송 동작을 말한다.Meanwhile, the ZigBee module 340 may calculate an effective humidity from humidity information generated by sensing the humidity sensor 320 and control an operation interval of the wireless sensor node 300 according to the calculated effective humidity. Here, the operation of the wireless sensor node 300 refers to a sensing operation by the sensors 310, 320, and 330 and a transmission operation by the Zigbee module 340.
구체적으로, 1) 실효 습도가 높은 경우, 지그비 모듈(340)은 무선 센서 노드(300)의 동작 간격을 크게(예를 들어, 30분 간격으로) 설정하고, 2) 실효 습도가 낮은 경우, 지그비 모듈(340)은 무선 센서 노드(300)의 동작 간격을 작게(예를 들어, 10분 간격으로) 설정한다.Specifically, 1) when the effective humidity is high, the Zigbee module 340 sets the operation interval of the wireless sensor node 300 to be large (for example, every 30 minutes), and 2) when the effective humidity is low, the Zigbee module 340. The module 340 sets the operation interval of the wireless sensor node 300 to be small (for example, at 10 minute intervals).
실효 습도가 낮은 경우는 산불이 발생할 가능성이 높은 경우이므로, 무선 센서 노드(300)의 동작 간격을 작게 설정한다. 반면, 실효 습도가 높은 경우는 산불이 발생할 가능성이 작은 경우이므로, 무선 센서 노드(300)의 동작 간격을 크게 설정한다.When the effective humidity is low, since there is a high possibility that a fire occurs, the operation interval of the wireless sensor node 300 is set small. On the other hand, when the effective humidity is high, since a fire is less likely to occur, the operation interval of the wireless sensor node 300 is set large.
무선 센서 노드(300)는 배터리를 통해 동작하는데, 위 동작 간격 제어에 의해 전력 소모가 보다 효율적으로 이루어지게 된다.The wireless sensor node 300 operates through a battery, and power consumption is made more efficient by controlling the operation interval.
다시, 도 2를 참조하여 중계장치(200)의 구성들에 대해 상세히 설명한다. 도 2에 도시된 바와 같이, 중계장치(200)는 디지털 송수신 장치(210), 싱크 노드(220), 피뢰침(230), 감시 카메라(240) 및 전원 공급부(250)를 구비한다.Again, the configurations of the relay apparatus 200 will be described in detail with reference to FIG. 2. As shown in FIG. 2, the relay device 200 includes a digital transceiver 210, a sink node 220, a lightning rod 230, a surveillance camera 240, and a power supply 250.
디지털 송수신 장치(210)는 원격에 위치하는 관제 센터(100)와 무선으로 통신 가능하도록 연결되어, 정보를 송수신한다.The digital transceiver 210 is connected to the remote control center 100 so as to communicate wirelessly, and transmits and receives information.
디지털 송수신 장치(210)에서 관제 센터(100)로 전송되는 정보에는, 후술할 센싱 정보, 영상 정보 및 전원 상태 정보가 있다. 한편, 관제 센터(100)에서 디지털 송수신 장치(210)로 전송되는 정보에는 산불 정보가 있다.Information transmitted from the digital transceiver 210 to the control center 100 includes sensing information, image information, and power state information, which will be described later. On the other hand, the information transmitted from the control center 100 to the digital transceiver 210 includes forest fire information.
피뢰침(230)은 감시 카메라(240)의 낙뢰에 의한 손상을 방지하기 위한 설비이다.Lightning rod 230 is a facility for preventing damage caused by lightning of surveillance camera 240.
감시 카메라(240)는 감시 영역을 촬영하여 영상을 생성한다. 감시 카메라(240)의 촬영 여부 및 촬영 방향은 무선 센서 노드들(300-1 내지 300-3)에 의해 센싱된 정보들에 기초한다.The surveillance camera 240 photographs a surveillance area to generate an image. Whether or not the monitoring camera 240 is photographed is based on information sensed by the wireless sensor nodes 300-1 to 300-3.
구체적으로, 감시 카메라(240)는 무선 센서 노드들(300-1 내지 300-3)에 의해 생성된 습도들로부터 산출한 감시 영역의 실효 습도가 기준치 이상인 경우에만 촬영을 수행한다. 즉, 실효 습도가 기준치 미만인 경우에, 감시 카메라(240)는 후술할 전원 공급부(250)로부터 인가되는 전원을 차단시킨다.In detail, the surveillance camera 240 photographs only when the effective humidity of the surveillance region calculated from the humidity generated by the wireless sensor nodes 300-1 to 300-3 is equal to or greater than a reference value. That is, when the effective humidity is less than the reference value, the surveillance camera 240 cuts off the power applied from the power supply 250 to be described later.
한편, 감시 카메라(240)의 촬영방향은 이산화탄소 농도가 기준치 이상인 센서 노드가 위치한 방향이다. 이를 위해, 감시 카메라(240)에는 무선 센서 노드들(300-1 내지 300-3)의 위치들에 대한 정보가 저장되어 있다.On the other hand, the photographing direction of the surveillance camera 240 is the direction in which the sensor node with the carbon dioxide concentration is higher than the reference value. To this end, the surveillance camera 240 stores information on the positions of the wireless sensor nodes 300-1 to 300-3.

The power supply state includes an operating state of the generators 251 and 253 and the capacitor 252 and a state of charge of the battery 252.
본 실시예에서 전원 공급부(250)는 풍력 발전기(251)과 태양광 발전기(253)를 통해 전원을 생성하는 것을 상정하였으나, 언급된 발전기들(251, 253)은 다른 종류의 발전기(예를 들면, 지열 발전기, 수력 발전기)로 대체될 수 있음은 물론이다.In the present embodiment, the power supply unit 250 is assumed to generate power through the wind generator 251 and the solar generator 253, but the generators 251 and 253 mentioned are other types of generators (for example, Of course, it can be replaced by a geothermal generator, a hydroelectric generator.
