Description

휴대용 액체 인화물 및 금속 탐지기 및 이를 이용한 액체 인화물 및 금속 탐지 방법Portable Liquid Phosphorus and Metal Detector and Liquid Phosphorus and Metal Detection Method Using the Same
본 발명은 휴대용 액체 인화물 및 금속 탐지기 및 이를 이용한 액체 인화물 및 금속 탐지 방법에 관한 것으로서, 보다 상세하게는 유리나 플라스틱 용기에 담겨져 있는 액체 인화물을 개봉하지 않고 탐지함은 물론 동시에 총기류와 같은 금속 물질을 탐지할 수 있는 휴대용 액체 인화물 및 금속 탐지기 및 이를 이용한 액체 인화물 및 금속 탐지 방법에 관한 것이다.The present invention relates to a portable liquid phosphide and metal detector and a liquid phosphide and metal detection method using the same, and more particularly, to detect a liquid phosphide contained in a glass or plastic container without opening, as well as to detect a metallic material such as a firearm. The present invention relates to a portable liquid phosphide and metal detector and a liquid phosphide and metal detection method using the same.
불안정한 국제정세, 사회불안 등으로 각종 테러의 위협이 가중되고 있는 상황에서 항공기, 지하철, 버스 등 공공장소에서 위험물의 반입을 사전에 방지할 수 있는 검사장비의 수요가 증대되고 있다.As the threat of terrorism is increasing due to unstable international situation and social unrest, there is an increasing demand for inspection equipment that can prevent the introduction of dangerous goods in public places such as aircraft, subways and buses.
특히, 대구 지하철에서의 시너(thinner)에 의한 참사사건, 국보 1호인 숭례문 시너 방화사건 등에서와 같이 비교적 반입이 용이한 가연성 액체를 페트병에 넣어서 반입하여 방화를 하는 경우가 늘고 있다. 또한, 영국 런던공항 액체폭탄 사건에서의 경우와 같이 손쉽게 액체 폭발물을 휴대함으로써 공공장소에서 많은 인명피해를 입힐 수 있는 폭발물을 탐지할 수 있는 탐지기가 절실히 필요한 실정이다.    In particular, as in the case of a catastrophe caused by thinners in Daegu subway, and the case of Sungnyemun Shinner Arson, which is the National Treasure No. 1, there is an increasing number of cases where a flammable liquid that is relatively easy to carry is put in a PET bottle and fired. In addition, there is an urgent need for a detector that can detect explosives that can cause a lot of casualties in public places by carrying liquid explosives easily as in the case of a liquid bomb incident in London Airport.
그러나, 공항을 제외한 거의 모든 공공장소나 대중교통 등에서 위험물 검사는 용이하지 않은 실정이다. 일반적으로 기존의 위험물 검사는 일정한 시간을 필요로 하는 화학분석에 의하여 수행되는데, 현실적으로 불가능하기 때문에 결국 육안이나 냄새 또는 직접 손으로 확인하게 된다. 이러한 방식의 위험물 검사는 정확도가 매우 낮으며, 개인사생활 침해 문제와 시간지연 등 여러 문제점을 가지고 있다. 또한, 대부분의 탐지기는 자력선을 이용하여 총기나 금속류의 유무만을 판단할 수 있으며, 금속성 물질이 아닌 액체 인화물, 액체 폭발물 등은 탐지가 불가능하므로 급변하는 테러양상에 대비하기가 어렵다.However, the inspection of dangerous goods is not easy in almost all public places and public transportation except the airport. In general, the existing dangerous goods inspection is performed by chemical analysis that requires a certain time, and since it is impossible in reality, it is finally confirmed by the naked eye or by smell or by hand.

도 9를 참조하면, 물의 반사파 정도 즉, 원래 임펄스 신호 크기와 반사된 반사파의 크기의 비율은 약 80%이며, 가솔린의 반사파 정도는 약 17% 정도이다. 액체 물질별로 유전율이 상이하기 때문에, 반사파 정도 역시 상이하게 나타난다. 이러한 액체별로 반사파 정도가 상이하게 나타남을 이용하여, 인화물 및 비인화물을 포함하는 다양한 액체별 반사파 정도를 데이터화하여 데이터 저장부에 저장시킨다. 제어부(300)에서는 액체 인화물 탐지부(100)에서 처리된 반사파를 인가받아, 메모리에 기저장된 액체별 반사파 정도와 비교하여, 액체 인화물 탐지부(100)에서 탐지된 액체가 인화물인지 또는 비인화물인지 여부를 판별하거나, 또는 제어부(300)는 액체 인화물 탐지부(100)로부터 수신한 반사파 정도가 기준값 미만일 경우 이를 인화물로 판별한다.Referring to FIG. 9, the ratio of the reflected wave of water, that is, the ratio of the magnitude of the original impulse signal and the reflected reflected wave is about 80%, and the reflected wave of the gasoline is about 17%. Since the dielectric constant is different for each liquid material, the degree of reflected wave is also different. Since the degree of reflected waves is different for each liquid, the degree of reflected waves for various liquids including phosphide and non-phosphide are converted into data and stored in the data storage unit. The control unit 300 receives the reflected wave processed by the liquid phosphide detection unit 100, and compares the degree of the reflected wave for each liquid previously stored in the memory to determine whether the liquid detected by the liquid phosphide detection unit 100 is phosphide or non-phosphorus. The control unit 300 determines whether the reflection wave received from the liquid phosphide detection unit 100 is less than the reference value as a phosphide.

여기서, k는 상수, L은 전파속도, c 는 광속도이며, μ는 액체별 유전율 계수이다. 전파 지연시간이란 반사파의 진폭이 기준값 미만으로 떨어지는데 소요되는 시간을 의미한다.Where k is a constant, L is the propagation speed, c is the speed of light, and μ is the permittivity coefficient for each liquid. The propagation delay time refers to the time taken for the amplitude of the reflected wave to fall below the reference value.
도 10에 도시된 바와 같이, 인화물 중 하나인 가솔린의 전파 지연시간은 1.41k이며, 비인화물 중 하나인 물의 전파 지연시간은 8.94k이다. 이와 같이, 비인화물의 전파 지연시간이 인화물의 전파 지연시간 보다 상대적으로 크다는 것을 알 수 있다. As shown in FIG. 10, the propagation delay time of gasoline which is one of the phosphides is 1.41k, and the propagation delay time of water which is one of the non-phosphorus is 8.94k. As such, it can be seen that the propagation delay time of the non-phosphorus is relatively larger than the propagation delay time of the phosphide.
액체별로 전파 지연시간이 상이하게 나타남을 이용하여, 인화물 및 비인화물을 포함하는 다양한 액체별 전파 지연시간을 데이터화하여 데이터 저장부에 저장시킨다. 제어부(300)에서는 액체 인화물 탐지부(100)에서 처리된 반사파를 인가받아, 메모리에 기저장된 액체별 전파 지연시간과 비교하여, 액체 인화물 탐지부(100)에서 탐지된 액체가 인화물인지 또는 비인화물인지 여부를 판별하거나, 또는 제어부(300)는 액체 인화물 탐지부(100)로부터 수신한 전파 지연시간이 기준값 미만일 경우 이를 인화물로 판별한다.By using different propagation delay times for each liquid, various liquid propagation delay times, including phosphide and non-phosphide, are converted into data and stored in the data storage unit. The control unit 300 receives the reflected wave processed by the liquid phosphide detection unit 100 and compares the propagation delay time for each liquid previously stored in the memory to determine whether the liquid detected by the liquid phosphide detection unit 100 is phosphide or non-phosphorus. The control unit 300 determines whether or not the propagation delay time received from the liquid phosphide detection unit 100 is less than the reference value as a phosphide.

도 15는 본 발명의 예시적인 실시예에 따른 휴대용 액체 인화물 및 금속 탐지기의 전체적인 동작을 설명하기 위한 도이다. 도 15를 참조하여 본 발명의 예시적인 실시예에 따른 휴대용 액체 인화물 금속 탐지기의 전체적인 동작을 설명한다.15 is a view for explaining the overall operation of the portable liquid phosphide and metal detector according to an exemplary embodiment of the present invention. Referring to Figure 15, the overall operation of a portable liquid phosphide metal detector according to an exemplary embodiment of the present invention will be described.
액체 인화물 탐지부(100)는 임펄스 신호를 발생한 후, 발생된 임펄스 신호를 액체 인화물 탐지에 적합한 크기의 신호로 증폭시키는 과정을 수행한다(S11). 임펄스 신호는 송신 안테나를 통하여 액체 탐지 대상물로 전송된다(S12). 액체 탐지 대상물로 전송된 임펄스 신호의 일부는 액체 탐지 대상물을 투과하며, 일부는 반사된다. 이러한 반사파는 액체 인화물 탐지부(100)의 수신 안테나를 통하여 수신되며, 수신된 반사파는 증폭 및 노이즈가 제거된다(S13). 신호 처리된 반사파는 제어부(300)로 전송된다(S14).After generating the impulse signal, the liquid phosphide detection unit 100 amplifies the generated impulse signal into a signal having a size suitable for detecting the liquid phosphide (S11). The impulse signal is transmitted to the liquid detection object through the transmitting antenna (S12). Part of the impulse signal sent to the liquid detection object passes through the liquid detection object, and part is reflected. The reflected wave is received through the receiving antenna of the liquid phosphide detector 100, and the received reflected wave is amplified and noise is removed (S13). The signal-processed reflected wave is transmitted to the controller 300 (S14).
제어부(300)에서는 액체 인화물 탐지부(100)로부터 수신한 반사파의 반사파 정도 및 전파 지연시간을 측정하는 과정을 수행한다(S15). 그리고 나서, 미리 저장된 액체별 반사파 정도과 측정된 반사파 정도를 비교하여 액체 탐지 대상물이 인화물인지 여부를 판단한다. 또한, 미리 저장된 액체별 전파 지연시간과 측정된 반사파의 전파 지연시간을 비교하여 액체 탐지 대상물이 인화물인지 여부를 판단한다(S16). 제어부(300)에서 액체 탐지 대상물의 인화물 판별 시, 측정된 반사파의 반사파 정도나 전파 지연시간 중 어느 하나만을 사용하여 판별할 수 있다. 보다 정확한 판단을 위하여 2가지 방식을 모두 사용하여 인화물 여부를 판별할 수도 있다.The controller 300 performs a process of measuring the reflected wave degree and the propagation delay time of the reflected wave received from the liquid phosphide detector 100 (S15). Then, it is determined whether the liquid detection object is a phosphide by comparing the degree of the reflected wave for each liquid and the measured degree of the reflected wave. In addition, it is determined whether the liquid detection target is a phosphide by comparing the propagation delay time of the liquid stored in advance with the measured propagation delay time of the reflected wave (S16). When the control unit 300 determines the phosphide of the liquid detection object, it may be determined using only one of the measured reflected wave degree and propagation delay time of the reflected wave. For more accurate judgment, both methods may be used to determine whether or not a phosphide is used.
제어부(300)에서 액체 탐지 대상물을 인화물로 판별한 경우, 인화물 탐지를 사용자에게 알리기 위하여 제어부(300)는 알람부 작동 명령신호를 알람부(500)로 전송한다(S17). 알람부(500)는 제어부(300)의 명령신호에 따라 진동 알람 유닛과 음향 알람 유닛 중 어느 하나 또는 그 조합을 작동시켜서, 사용자에게 액체 인화물이 탐지되었음을 알려준다(S30).When the control unit 300 determines that the liquid detection target is phosphide, the control unit 300 transmits an alarm operation command signal to the alarm unit 500 in order to notify the user of phosphide detection (S17). The alarm unit 500 operates one or a combination of the vibration alarm unit and the acoustic alarm unit according to the command signal of the controller 300 to inform the user that liquid phosphide is detected (S30).
한편, 금속 탐지부(200)는 액체 인화물 탐지부(100)와 독립적으로 작동한다. 이러한 금속 탐지부(200)의 동작을 상펴보면, 우선 제어부(300)에서 금속 탐지부(200)로 감도 조절 명령신호를 전송한다(S21). 그 다음, 금속 탐지부(200)는 제어부(300)에서 전송된 감도 조절 명령신호에 따라 금속 탐지부의 감도 조절값이 설정된다(S22). 설정된 감도 조절값의 범주 내에서 금속의 존재 여부를 탐지한다(S23). 금속 탐지 결과를 제어부(300)로 전송하며(S24), 제어부(300)에서는 금속 탐지를 사용자에게 알리기 위하여 알람부 작동 명령신호를 알람부(500)로 전송한다(S25).On the other hand, the metal detector 200 operates independently of the liquid phosphide detector 100. Looking at the operation of the metal detector 200, first, the control unit 300 transmits a sensitivity control command signal to the metal detector 200 (S21). Next, the metal detector 200 sets a sensitivity control value of the metal detector according to the sensitivity control command signal transmitted from the controller 300 (S22). The presence of the metal within the range of the set sensitivity control value is detected (S23). The metal detection result is transmitted to the control unit 300 (S24), and the control unit 300 transmits an alarm unit operation command signal to the alarm unit 500 to notify the user of the metal detection (S25).
알람부(500)는 제어부(300)의 명령신호에 따라 진동 알람 유닛과 음향 알람 유닛 중 어느 하나 또는 그 조합을 작동시켜서, 사용자에게 금속이 탐지되었음을 알려준다(S30).The alarm unit 500 operates one or a combination of the vibration alarm unit and the acoustic alarm unit according to the command signal of the controller 300 to inform the user that metal is detected (S30).

임펄스 신호를 액체 탐지 대상물로 전송하는 과정을 수행한다(S152). 액체 탐지 대상물에 반사되어 돌아온 반사파 수신하는 과정을 수행한다(S153). 이러한 반사파는 수신 안테나를 통하여 수신되며, 수신 모듈과 신호 처리 모듈을 거치면서 증폭된 후, 노이즈가 제거된다. A process of transmitting an impulse signal to a liquid detection target is performed (S152). In operation S153, the reflection wave returned by the liquid detection target is received. The reflected wave is received through the receiving antenna, amplified through the receiving module and the signal processing module, and then the noise is removed.
반사파의 반사파 정도를 측정한 후(S154), 제어부에서는 측정된 반사파 정도와 기준값을 비교하여, 반사파 정도가 기준값 미만인지 여부를 판단한다(S155). 판단 결과, 반사파 정도가 기준값 미만일 경우에는 액체 탐지 대상물이 인화물인 경우로서, 알람부를 작동시켜서 사용자에게 액체 탐지 대상물이 인화물임을 알려준다(S156).After measuring the reflected wave degree of the reflected wave (S154), the controller compares the measured reflected wave degree with a reference value to determine whether the reflected wave degree is less than the reference value (S155). As a result of the determination, when the degree of the reflected wave is less than the reference value, the liquid detection object is a phosphide, and the alarm unit is operated to inform the user that the liquid detection object is phosphide (S156).
도 17은 본 발명의 휴대용 액체 인화물 및 금속 탐지기를 이용하여 액체 인화물을 탐지하는 예시적인 다른 방법을 나타내는 흐름도이다. 17 is a flow diagram illustrating another exemplary method of detecting liquid phosphide using the portable liquid phosphide and metal detector of the present invention.

임펄스 신호를 액체 탐지 대상물로 전송하는 과정을 수행한다(S162). 액체 탐지 대상물에 반사되어 돌아온 반사파 수신하는 과정을 수행한다(S163). 이러한 반사파는 수신 안테나를 통하여 수신되며, 수신 모듈과 신호 처리 모듈을 거치면서 증폭된 후, 노이즈가 제거된다. In operation S162, an impulse signal is transmitted to the liquid detection target. The process of receiving the reflected wave reflected back to the liquid detection target is performed (S163). The reflected wave is received through the receiving antenna, amplified through the receiving module and the signal processing module, and then the noise is removed.
반사파의 전파 지연시간을 측정한 후(S164), 제어부에서는 측정된 반사파의 전파 지연시간과 기준값을 비교하여, 반사파의 전파 지연시간이 기준값 미만인지 여부를 판단한다(S165). 판단 결과, 반사파의 전파 지연시간이 기준값 미만일 경우에는 액체 탐지 대상물이 인화물인 경우로서, 알람부를 작동시켜서 사용자에게 액체 탐지 대상물이 인화물임을 알려준다(S166).After measuring the propagation delay time of the reflected wave (S164), the controller compares the measured propagation delay time of the reflected wave with a reference value to determine whether the propagation delay time of the reflected wave is less than the reference value (S165). As a result of the determination, when the propagation delay time of the reflected wave is less than the reference value, the liquid detection object is a phosphide, and an alarm unit is operated to inform the user that the liquid detection object is a phosphide (S166).
