Abstract

The present invention relates to a contactless breathalyzer and, more specifically, to a technology for a contactless breathalyzer which is not a conventional method wherein a driver blows into the breathalyzer with his/her mouth to measure the amount of alcohol but a method applied to determine whether or not the driver has drunk alcohol without requiring the driver to forcibly blow into the breathalyzer with his/her mouth by suctioning the air around an automotive driver seat of the driver with the contactless breathalyzer and passing the same through an alcohol sensor built-in the breathalyzer when drunk driving is suspected. The present invention is a means to provide the contactless breathalyzer to prevent transmission of viruses, wherein the contactless breathalyzer is formed of a structure in which a funnel-shaped air collection part, an alcohol detection part, and an air suction part are combined. When drunk driving enforcement is required, the air around the drivers forcibly passes the breathalyzer through the air collection part, and the alcohol detection part built-in the breathalyzer can determine whether or not the driver was driving under the influence of alcohol.

Description

비접촉식 음주측정기 및 음주 측정방법{Proximity contactless style drunkometer and alcohol measuring method}{Proximity contactless style drunkometer and alcohol measuring method}

본 발명은 비접촉식 음주 측정 장치에 관한 것으로, 더 상세하게는 운전자들이 직접 자신의 입으로 음주 측정기를 불어서 음주량을 측정하던 종래의 방식이 아니라 취객운전이 의심되는 경우 운전자들에게 음주측정기를 입에 대고 강제로 불어달라고 요구하는 대면접촉방식이 아니라 운전자의 차량 운전석 주변 공기를 비접촉식 음주측정기로 흡입시켜 측정장치에 내장된 알콜감지센서를 거치도록 하여 운전자의 음주여부를 판정할 수 있도록 적용되는 비접촉식 음주 측정기에 관한 것이다.The present invention relates to a non-contact type breathalyzer, and more particularly, when drivers are suspected of drunk driving, rather than the conventional method in which drivers directly blow a breathalyzer to measure alcohol consumption, they hold the breathalyzer to their mouths. A non-contact type breathalyzer applied to determine whether the driver is drinking alcohol by inhaling the air around the driver's vehicle driver's seat with a non-contact type breathalyzer and passing through an alcohol detection sensor built into the measurement device, rather than a face-to-face contact method requiring forcibly blowing. It is about.

일반적으로, 교통사고의 발생요인 중에 운전자의 음주에 의한 교통사고율이 높게 나타나고 있으며, 또한 운전자의 음주운전에 기인한 교통사고율이 증가하면서 그에 따른 사고도 점차 대형화하고 있다.In general, among the causes of traffic accidents, the traffic accident rate due to the driver's drinking is high, and the traffic accident rate caused by the driver's drunk driving is increasing, and the resulting accident is gradually increasing.

이러한 음주운전을 예방하기 위하여, 음주운전단속 경찰관들은 도로상에서 음주 측정기를 운전자들의 입으로 들이밀고 강제로 불개하여 음주운전을 단속해 왔었다.In order to prevent such drunk driving, the drunk driving police officers have been cracking down on drunk driving by pushing a breathalyzer into drivers' mouths on the road and forcibly dismissing them.

그러나, 2020년에는 세계적으로 코로나 바이러스 19의 발생으로 인하여 코로나 바이러스 확산을 방지하기 위해 사회적 거리두기가 시행되고, 비대면이 일상이 되어버린 상황이고, 철저한 방역대비로 잠시 잠잠해질만하면 다시 적극적 대면접촉으로 코로나19가 확산되는 양태로 인해 전 세계가 긴장을 늦출 수 없는 상황이다.However, in 2020, due to the outbreak of Coronavirus 19 worldwide, social distancing has been implemented to prevent the spread of the coronavirus, and non-face-to-face has become a daily routine. As a result of the spread of Corona 19, the entire world cannot relax.

코로나19는 비말로 인해 감염이 되기 때문에 마스크를 필수적 쓰는 게 생활화가 되어버렸고 이로 인해 난감한 상황이 여러 군데에서 드러나고 있는데 그중 대표적인 분야가 바로 음주운전 단속이라고 할 수 있고 최근엔 비접촉 음주단속이 요구되고 있다.Corona 19 is infected by droplets, so wearing a mask has become a daily routine, and this has revealed a difficult situation in many places, and the representative field of which is the drunk driving crackdown, and recently, non-contact drinking crackdown is required.

또한 최근 윤창호 법으로 인해 음주단속 처벌이 강화되고, 음주운전 단속이 한창이었는데 코로나19로 인해 음주운전 단속도 조심스러울 수밖에 없는바, 기존 음주 측정 방식은 입으로 힘껏 숨을 불어넣는 형태였기 때문에 바이러스로 인한 감염 위험으로 한동안 음주 측정을 하지 못했고, 이런 틈을 타 음주운전을 하는 운전자가 많아지면서 크고 작은 사고들이 늘어나고 있는 상황이었다. In addition, due to the Yoon Chang-ho Act, the drinking crackdown was intensified, and the crackdown on drunk driving was in full swing, but due to Corona 19, the crackdown on drunk driving was inevitable. Due to the risk of infection caused by the risk of infection, alcohol consumption was not measured for a while, and as more and more drivers drunk driving during this time, accidents large and small were increasing.

이러한 상황변화로 인하여 비접촉식 음주단속 방법이 요구되었고, 최근 일부에서 비접촉 음주단속 측정수단으로 운전석 창문을 살짝 열어두고 약 60cm 길이가 되는 지지대 끝부분에 커버를 씌운 알콜감지기를 달아 차량 내에 들이 밀고 알코올 입자가 일정 수준 이상이 되었을 땐 감지기에서 소리가 울리고, 불빛이 들어오는 방식으로 운전자가 직접 입으로 불지 않아도 감지기가 스스로 운전자의 알코올 지수를 측정할 수 있도록 하고자 시도되었으나 바쁜 퇴근시간에 통행 차량을 세워놓고 알콜감지기를 차량 내부에 들이 밀고 알코올 입자가 일정 수준 이상이 되기까지 차량당 1분 이상이 소요되는 시간을 기다리라고 하는 것은 많은 불편과 민원을 야기하였고, 또한 비접촉식 감지기를 통해 음주를 측정하다 보니 차 안에서 손소독제를 사용한 운전자들에게도 알코올이 감지되는 등 불합리적인 부분들이 나타나서 이의 적용에 어려움이 있어 왔다.Due to this change in circumstances, a non-contact alcohol control method was required, and in some recent cases, the driver's window is slightly open as a non-contact alcohol control measure, and an alcohol detector with a cover on the end of the support, which is about 60 cm long, is attached to the vehicle and is pushed into the vehicle. When is above a certain level, the detector makes a sound and the light comes on. An attempt was made to allow the detector to measure the driver's alcohol level by itself without the driver's mouth blowing. It caused a lot of inconvenience and complaints to push the inside of the vehicle and wait for more than 1 minute per vehicle to reach a certain level of alcohol particles.Also, as drinking alcohol was measured through a non-contact sensor, the hand inside the car Even drivers who used disinfectants had difficulty in applying them because alcohol was detected and irrational parts appeared.

본 발명은 최근 코로나19로 인해 음주운전 단속과정에서 종래와 같이 음주 측정기를 입으로 힘껏 숨을 불어넣는 형태로 적용하지 못하게 됨에 따라 운전자의 차량 운전석 주변의 공기를 비접촉식 음주 측정 장치로 강제 흡입시켜 음주 측정 장치에 내장된 알콜감지센서가 운전자의 음주여부를 판정할 수 있도록 적용되는 비접촉식 음주 측정기를 제공하고자 하는 목적을 갖는다.Due to the recent Corona 19, in the process of controlling drunk driving, the present invention cannot be applied in the form of inhaling the breathalyzer with the mouth as hard as in the prior art. Accordingly, the air around the driver's seat of the driver is forcibly inhaled with a non-contact breathalyzer. The purpose of this is to provide a non-contact type breathalyzer that is applied so that the alcohol detection sensor built into the measuring device can determine whether the driver is drinking alcohol.

본 발명에 의한 음주 측정 장치는, 외부 전염원을 방지하기 위한 비접촉식 음주 측정기로 제공하고자 하는 기술로, 깔대기 형상의 시료채취부와 알콜감지센서 및 음주측정제어부와 연계된 알콜감지부와 강제흡입수단이 상호 결합된 구조로 비접촉식 음주 측정기를 이루어서 음주단속이 필요한 경우 시료채취부를 통하여 운전자 주변을 공기를 강제흡입수단을 통하여 음주 측정기를 통과시키고 음주측정기의 알콜감지센서를 이용하여 운전자의 음주여부를 비접촉식으로 판정할 수 있도록 제공되는 비접촉식 음주 측정기를 특징으로 한다.The alcohol measurement device according to the present invention is a technology to be provided as a non-contact type breathalyzer for preventing external sources of infectiousness, and includes a funnel-shaped sample collection unit, an alcohol detection sensor, and an alcohol detection unit and a forced inhalation unit connected to the alcohol detection control unit. When drinking control is necessary by forming a non-contact breathalyzer with a mutually coupled structure, air is passed around the driver through the sample collection unit through the forced inhalation means, and the alcohol detection sensor of the breathalyzer is used to determine whether the driver is drinking alcohol in a non-contact manner. It features a non-contact breathalyzer provided to be able to determine.

본원 음주 측정기 내부에 내장되는 알콜감지센서는 주석산화물(SnO2) 무기물이 세라믹 관에 코팅되고 백금 전극이 장착된 구성을 이루고 알콜 분자가 세라믹 관을 통과하게 되면 전자가 튀어나와 백금 전극에 전류가 흐르게 되는 원리가 적용되는 알콜감지센서가 사용되도록 적용될 수 있으며, 본원 음주측정기에 사용되는 강제흡입수단은 흡입펌프, 주사기, 플런저, 흡입 건(trigger), 스크류, 흡입피더 등 다양한 형태로 운전석 등의 시료채취부에 있는 외부공기를 음주 측정기 내부로 유인하는 강제흡입기능을 갖는 것은 제한없이 사용될 수 있다.The alcohol detection sensor built into the breathalyzer of the present is composed of tin oxide (SnO 2 ) inorganic material coated on a ceramic tube and a platinum electrode mounted. When alcohol molecules pass through the ceramic tube, electrons pop out and current flows to the platinum electrode. The alcohol detection sensor to which the principle of flow is applied can be applied, and the forced suction means used in the present breathalyzer is in various forms such as a suction pump, a syringe, a plunger, a suction gun, a screw, a suction feeder, etc. Anything that has a forced inhalation function that induces outside air in the sample collection unit into the breathalyzer can be used without limitation.

따라서 본원 기술은 외부 전염원을 방지하기 위한 비접촉식 음주 측정방법으로 적용되는 기술로써, 코로나 19 바이러스 등 외부 전염원을 방지하기 위한 수단으로 비접촉식 음주 측정을 실시하기 위한 방법으로서, 깔대기 형상의 시료채취부와 알콜감지센서 및 음주측정제어부와 연계된 알콜감지부와 강제흡입수단이 상호 결합된 구조의 비접촉식 음주측정기를 만드는 기기 제작단계와 음주단속이 필요한 경우 상기 비접촉식 음주측정기의 시료채취부를 통하여 단속 전 주변환경의 공시료를 채취하여 기준알콜농도를 확인하는 공시료 측정단계와 운전자 주변의 공기를 음주측정기를 통과시켜 알콜농도를 확인하고 공시료 측정단계에서 얻은 결과와 비교한 차등 연산을 수행한 결과로 알콜농도를 연산시켜 음주여부를 판정하는 단계를 포함하여 비접촉식 음주 측정이 이루어지도록 적용되는 비접촉식 음주 측정방법이 구현될 수 있다.Therefore, the present technology is a technology applied as a non-contact alcohol measurement method to prevent external infectious sources, and as a method for conducting non-contact alcohol consumption measurement as a means to prevent external infectious sources such as the Corona 19 virus, a funnel-shaped sample collector and alcohol In the case of a device manufacturing step of making a non-contact breathalyzer with a structure in which the alcohol detection unit and forced inhalation unit linked to the detection sensor and the alcohol consumption measurement control unit are mutually combined, and when drinking control is necessary, the sample collection unit of the non-contact type breathalyzer is used to monitor the surrounding environment before the crackdown. Alcohol concentration as a result of performing a differential calculation comparing the result obtained in the blank sample measurement step, which collects blank sample and checks the standard alcohol concentration, and checks the alcohol concentration by passing the air around the driver through a breathalyzer. A non-contact alcohol measurement method applied to perform non-contact alcohol consumption measurement, including the step of determining whether or not to drink alcohol, may be implemented.

상기 비접촉식 음주 측정방법에서 음주측정기를 통하여 차등연산을 수행한 결과로 얻은 알콜농도에 따른 음주여부의 판정결과에서 기준농도 이하는 녹색으로 기준농도 이상은 적색으로 표시되는 디지탈표시부를 포함하도록 적용되는 접촉식 음주 측정방법으로 구현될 수 있다.In the non-contact method for measuring alcohol consumption, the contact applied to include a digital display unit in which the reference concentration is displayed in green and above the reference concentration in red in the determination result of alcohol consumption according to the alcohol concentration obtained as a result of performing the differential calculation through the breathalyzer. It can be implemented as a method of measuring drinking alcohol.

본원 기술사상이 구체적으로 구현되는 실시양태는 하기의 발명을 실시하기 위한 구체적인 내용란 기재에서 도면과 함께 상세하게 설명된다.Embodiments in which the technical idea of the present application is specifically embodied will be described in detail with the drawings in the description of the detailed description for carrying out the following invention.

본원 기술은 최근 코로나19로 인해 대면 음주운전 단속을 실시할 수 없는 상황에서 바쁜 퇴근시간에 통행 차량을 세워놓고 알콜감지기를 차량 내부에 들이 밀고 알코올 입자가 일정 수준 이상이 되기까지 차량당 1분 이상이 소요되는 시간을 기다리 라고 하는 단속형태는 운전자에게 많은 불편 및 불쾌감으로 민원을 야기하게 되는 문제점을 해소하고 운전자의 입으로 불대를 불어달라고 요청하지 않고 차량 운전석 주변의 공기를 비접촉식 음주 측정기로 강제 흡입시켜 음주 측정기에 내장된 알콜감지센서가 운전자의 음주여부를 신속하게 판정할 수 있도록 적용되는 비접촉식 음주 측정기를 제공하여 음주운전을 미연에 방지하고 음주운전으로 인한 교통사고를 줄일 수 있는 효과를 제공한다.In a situation where face-to-face drunk driving crackdowns cannot be conducted due to the recent Corona 19, the technology of this application is to stop a passing vehicle during busy work hours and push the alcohol detector into the vehicle, and it takes more than 1 minute per vehicle until the alcohol particles reach a certain level. The enforcement form of waiting for the required time solves the problem that causes civil complaints due to a lot of inconvenience and discomfort to the driver, and forces the air around the driver's seat of the vehicle to be inhaled with a non-contact type breathalyzer without asking the driver to blow a fire in the mouth. The alcohol detection sensor built into the breathalyzer provides a non-contact breathalyzer that is applied to quickly determine whether the driver is drinking alcohol, thereby preventing drunk driving and reducing traffic accidents caused by drunk driving.

도 1은 본 발명의 일 실시양태에 따른 음주측정장치의 구성을 설명하기 위한 블럭도이고, 도 2는 본원의 음주측정장치에 설치되는 알콜감지센서의 일 실시양태를 나타낸 도면이다.1 is a block diagram for explaining the configuration of a breath measurement device according to an embodiment of the present invention, Figure 2 is a view showing an embodiment of an alcohol detection sensor installed in the breath measurement device of the present invention.

도 1을 참조하여 본 발명의 기술사상에 따른 음주 측정 장치는 시료채취부(10)와 알콜감지부(20) 알콜감지센서(30)와 음주측정제어부(40)와 강제흡입부(60) 및 배기부(60)를 갖는 구성으로 비접촉식 음주 측정기(100)가 제공된다.Referring to FIG. 1, the alcohol consumption measurement apparatus according to the technical idea of the present invention includes a sample collection unit 10, an alcohol detection unit 20, an alcohol detection sensor 30, a drinking measurement control unit 40, and a forced suction unit 60, and A non-contact breathalyzer 100 is provided in a configuration having an exhaust part 60.

도 1에 표시되는 시료채취부(10)가 상하 양쪽에 표시한 이유는 음주 측정기(100)의 정밀도를 높이기 위해 위쪽에 설치된 시료채취부(10)는 음주측정 장소 또는 온도,습도 등의 주변환경에 알콜성분을 포함한 세정제 등 의 사용에 따른 알콜량의 감지순도가 달라질 수 있는 오차요인을 줄이거나 배제하기 위해 음주측정 장소의 공시료를 음주측정기(100)의 흡입구동모터를 작동시켜 깔대기 형상의 위쪽 시료채취부(10)를 통하여 측정 장소(제1영역)의 외부공기 공시료를 음주측정기(100)로 유입시키고 알콜감지센서(30)를 거치며 알콜 농도를 측정하도록 하고 저부쪽에 표시된 또 하나의 시료채취부(10)는 실제적으로 운전자 차량내부(제2영역)에서의 측정되는 알콜농도를 측정하여 제1영역에서의 측정결과와 대비하도록 적용되는 구성을 설명하기 위해 시료채취부(10)가 상하 양쪽으로 배치한 것으로 시료채취부(10)는 외부공기 또는 운전석의 공기를 효율적으로 알콜 감지부(20)로 보내주기 위해 입구가 넓은 깔대기 형상으로 제공되는 것이 바람직하고, 알콜감지센서(30)와 음주측정제어부(40)와 연계되어 기능하는 알콜 감지부(20)에는 시료채취부(10)에서 수집되는 공기가 알콜감지센서(30)를 경유하여 흐르도록 유인하기 위해 강제흡입수단이 필요한바, 강제흡입수단은 소형 흡입펌프형태로 적용되거나, 또는 주사기로 일정량의 공기를 흡입하여 알콜 감지부(20)를 경유하여 통과되도록 적용되거나, 일정구간만 회전하는 플런저 등의 형태로 일정량 만큼의 공기가 시료채취부(10)를 통하여 유입된 후 알콜 감지부(20)에 내장된 형태의 알콜감지센서(30)를 경유하며 알콜농도가 측정되도록 적용될 수 있다.The reason that the sample collection unit 10 shown in FIG. 1 is displayed on both the top and bottom is that the sample collection unit 10 installed at the top in order to increase the precision of the breathalyzer 100 is the place of the drinking measurement or the surrounding environment such as temperature and humidity. In order to reduce or eliminate the error factor that may change the detection purity of the alcohol content due to the use of detergents including alcohol, the empty sample at the drinking measurement location is operated in a funnel shape by operating the suction drive motor of the breathalyzer 100. Through the upper sample collecting unit 10, the sample of external air from the measurement location (the first area) is introduced into the breathalyzer 100, and the alcohol concentration is measured through the alcohol detection sensor 30. The sample collection unit 10 actually measures the alcohol concentration measured inside the driver's vehicle (the second area) and compares the measurement result with the measurement result in the first area.

도 2는 본원의 음주측정장치(100)에 적용될 수 있는 알콜감지센서(30)로 MQ-3형 알콜감지센서의 사진도를 나타낸 것으로, 도 2a에서는 본원 기술에 사용되는 MQ3형 알콜감지센서(30)의 사진도를 나타낸 것이고, 도 2b에서는 MQ - 3 알콜감지센서의 작동원리를 설명하기 위해 내부구성을 확대하여 나타낸 것이다.2 is a photographic diagram of an MQ-3 type alcohol detection sensor as an alcohol detection sensor 30 that can be applied to the breathalyzer 100 of the present application, and in FIG. 2A, an MQ3 type alcohol detection sensor used in the present technology ( 30) is a photographic diagram, and in FIG. 2B, the internal configuration is enlarged to explain the operating principle of the MQ-3 alcohol sensor.

본원에서 사용하는 MQ - 3 알콜감지센서는 출원인이 직접 발명한 것이 아니고 외국산을 구매하여 본원의 음주측정장치에 적용가능성을 타진하며 실험한 결과 높은 정밀도를 나타냄을 확인하여 채택 사용하고자 하는 것으로, 본원에서 사용하는 MQ - 3 알콜감지센서는 아날로그핀과 디지털핀으로 값을 가져오는데 아날로그핀으로 알콜의 농도값을 측정하고 디지텅핀으로는 알콜의 유무를 측정할 수 있으며 도 2a와 같이 모듈형으로 이루어진 알콜센서의 경우 대부분 뒷면에 감도를 조절할 수 있는 가변저항이 달려 있어서 저항을 시계방향으로 돌리면 감도가 커지고 반시계방향으로 돌리면 감도가 작아지도록 감도조절(증폭)수단을 갖는 구조의 사용이 바람직하다.The MQ-3 alcohol detection sensor used in this application was not invented by the applicant directly, but was purchased from a foreign country and was tested for applicability to the drinking measuring device of the present company. The MQ-3 alcohol sensor used in the system takes values through analog pins and digital pins. It measures the concentration of alcohol with an analog pin and the presence or absence of alcohol with a digital pin. In the case of alcohol sensors, it is desirable to use a structure with a sensitivity control (amplification) means so that the sensitivity increases when the resistance is turned clockwise and the sensitivity decreases when the resistance is turned clockwise.

도 2b는 MQ - 3 알콜감지센서의 작동원리를 설명하기 위해 내부구성을 확대하여 나타낸 것으로 세라믹 관(21) 안쪽에 주석산화물(SnO2)인 무기물(22)이 코팅된 구성을 이루고 세라믹 관(21) 중심부에는 히팅코일(23)이 내장된 구조를 이루며 세라믹 관(21)일측에 백금전극(24)이 내장된 구성을 이루어서 음주측정기(100)의 시료채취부(10)로 유입된 공기 중에 포함된 알콜이 히팅코일(23)에 가열되는 상태로 백금전극을 만나면 에탄올이 아세트산으로 연소되면서 더 많은 전류가 생성됨에 따라서 알코올 분자가 많을수록 더 많은 전류를 얻을 수 있게 적용되는 원리를 이용하여 전류 변화값으로 인해 센서에서 서로 다른 비교 값을 얻을 수 있는 원리가 적용될 수 있는바, 더욱 상세하게는 주석산화물(SnO2) 내부의 히팅코일(23)이 가열받게 되면 코일을 감싸고 있는 SnO2 코팅 세라믹 관(21)이 열을 받아 반도체가 되고 여기에 알콜 분자가 닿게되면 전자가 튀어나와 백금 전극에 전류가 흐르게 되는데 알콜분자가 많을 수록 전자가 많이 튀어나오게 되고 전류도 많이 흐르게 되므로 이러한 전류의 흐르는 정도에 따라 유입된 공기 중의 알콜농도를 측정할 수 있게 되는 원리가 적용될 수 있다.2B is an enlarged view of the internal structure to explain the operation principle of the MQ-3 alcohol sensor. The ceramic tube 21 forms a configuration in which an inorganic material 22, which is tin oxide (SnO 2 ), is coated, and the ceramic tube ( 21) A heating coil 23 is embedded in the center, and a platinum electrode 24 is embedded on one side of the ceramic tube 21, so that the air flowing into the sample collecting section 10 of the breathalyzer 100 is When the contained alcohol is heated by the heating coil 23 and meets the platinum electrode, the ethanol is burned to acetic acid and more current is generated.Therefore, the more alcohol molecules, the greater the current is obtained using the applied principle. Because of the value, the principle of obtaining different comparison values from the sensor can be applied.In more detail, when the heating coil 23 inside the tin oxide (SnO 2 ) is heated, the SnO 2 coated ceramic tube surrounding the coil (21) This heat becomes a semiconductor, and when an alcohol molecule touches it, electrons pop out and a current flows through the platinum electrode.The more alcohol molecules, the more electrons come out and the more current flows. Accordingly, the principle of being able to measure the alcohol concentration in the introduced air can be applied.
