차량용 음주측정 장치 및 방법{apparatus and method for drinking test of automobile}Apparatus and method for drinking test of automobile}

본 발명은 차량용 음주측정 장치 및 방법에 관한 것으로, 보다 상세하게는운전자가 자동차를 운행하려고 할 경우 차량내부에 장착된 음주측정센서가 운전자의 호흡기로부터 배출되는 공기를 센싱하여 알콜농도를 감지하고, 운전자의 알콜농도가 법적 허용기준치를 초과할 경우 자동으로 자동차의 시동이 걸리지 않도록 함으로써 음주운전을 미연에 방지할 수 있도록 하는 차량용 음주측정 장치 및 방법에 관한 것이다.The present invention relates to a breathalyzer and a method for measuring a vehicle, and more particularly, when a driver attempts to drive a car, a breathalyzer detecting a alcohol concentration is sensed by sensing the air exhausted from the breather of the driver. The present invention relates to a vehicle breathalyzer and a method for preventing drunk driving in advance by preventing the driver from automatically starting the vehicle when the alcohol concentration exceeds the legal limit.

근래에 자동차가 생활의 필수품으로 정착되어 그 보급 대수가 급속히 증가 추세에 있다.Recently, automobiles have become a necessity of life, and the number of them is rapidly increasing.

자동차를 안전하게 운행하기 위해서는 무엇보다도 운전자가 안전에 대한 의식을 갖추어야 하며, 이러한 안전의식 부재로 인한 사고의 한 예로 음주운전 사고를 들 수 있다.In order to drive a car safely, the driver must be conscious of safety first of all, and an example of an accident caused by the lack of safety awareness is a drunk driving accident.

음주운전은 자신의 신체 및 재물의 손괴뿐만 아니라 타인의 목숨까지도 위태롭게 하므로 특히 주의해야 하며, 이러한 음주운전이 심각한 사회적인 문제로 대두되면서 그에 대한 벌칙이 강화되고 있는 실정이다.Drunk driving is particularly dangerous because it threatens not only the damage of one's body and wealth, but also the lives of others. As such drunk driving becomes a serious social problem, the penalties for it are being reinforced.

이와 같은 음주운전을 막아보고자 하여 운전자에게 강력한 법적인 제재가 행하여지고, 또한 음주자가 운전을 행하여 사고가 발생하는 경우 조수석에 탑승한 사람도 처벌되는 법규가 발효되었으나, 이는 음주운전 사고를 미연에 방지하기에는 역부족이었다.In order to prevent such drunk driving, a strong legal sanction is imposed on the driver, and when a drunk driver drives an accident, a law is also imposed on the passenger seated in the passenger seat. It was not enough.

그리고, 운전자를 위한 음주측정테스터기가 최근 발매되고 있으나, 이러한 테스터기의 경우 운전자 본인이 측정결과를 무시하고 운전을 할 수 있고, 이 경우 테스터기는 단순한 테스터기로서의 역할만 수행할 수밖에 없었다.In addition, although a drinking tester for a driver has been recently released, in the case of such a tester, the driver himself can ignore the measurement result and drive.

또한, 종래의 자동차는 운전자가 음주상태에서 자동차를 운행하려고 할 시 이를 거부하는 별도의 장치가 없어 음주상태의 운전을 미연에 방지할 수 없었으며, 경찰관에 의해 단속되는 음주운전은 단속시 여러 불편을 초래할 뿐만 아니라 비효율적인 문화의 양태로 지적되는 문제점이 있었다.In addition, the conventional car does not have a separate device that refuses when the driver attempts to drive the car in a drunk state, and thus cannot prevent driving in a drunk state. Not only did it cause problems, but it was pointed out as an inefficient aspect of culture.

이로 인해 갈수록 음주운전이 사회 문제화되고, 인적 및 물적 자원에서의 국가적인 손실이 발생하고 있는 실정이다.As a result, drunk driving becomes a social problem, and national losses in human and physical resources are occurring.

이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로서, 본 발명의 목적은 운전자가 자동차를 운행하려고 할 경우 차량내부에 장착된 음주측정센서가 운전자의 호흡기로부터 배출되는 공기를 센싱하여 알콜농도를 감지하고, 운전자의 알콜농도가 법적 허용기준치를 초과할 경우 자동으로 자동차의 시동이 걸리지 않도록 함으로써 음주운전을 미연에 방지할 수 있도록 하는 차량용 음주측정 장치 및 방법을 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to measure the alcohol concentration by sensing the air discharged from the driver's respiratory sensor is installed inside the vehicle when the driver tries to drive the car The present invention provides a vehicle and a drunk measuring device and method for preventing drunk driving in advance by preventing the driver from automatically starting the vehicle when the alcohol concentration of the driver exceeds the legal limit.

도 1은 본 발명의 실시예에 따른 차량용 음주측정 장치를 개략적으로 나타낸 블록도이고, 도 2는 도 1의 음주측정센서의 설치상태를 도시한 상태도이며, 도 3은 본 발명의 실시예에 따른 차량용 음주측정 방법을 나타낸 흐름도이다.1 is a block diagram schematically showing a vehicle breathalyzer measuring apparatus according to an embodiment of the present invention, Figure 2 is a state diagram showing the installation state of the breathalyzer sensor of Figure 1, Figure 3 according to an embodiment of the present invention It is a flowchart showing the alcohol breath measurement method for vehicles.

먼저, 도 1에 도시된 바와 같이 본 발명에 따른 차량용 음주측정 장치는 차량내부에 설치되어 운전자의 알콜농도를 감지하는 음주측정센서(10)와, 상기 음주측정센서(10)의 감지 결과를 디지털신호로 변환하는 A/D변환부(20)와, 상기 A/D변환부(20)의 출력을 인가받아 알콜농도를 비교 분석하는 마이컴(30)과, 상기 마이컴(30)의 출력에 엔진의 시동여부를 제어하는 엔진제어부(40)로 이루어진다.First, as shown in FIG. 1, a vehicle alcohol measuring apparatus according to the present invention is installed inside a vehicle to detect a alcohol concentration of a driver 10 and a alcohol detection sensor 10 and digitally detect a detection result of the alcohol measurement sensor 10. A / D converter 20 for converting the signal, the microcomputer 30 for comparing and analyzing the alcohol concentration by receiving the output of the A / D converter 20, and the output of the microcomputer 30 It consists of an engine control unit 40 for controlling whether to start.

상기 음주측정센서(10)는 운전자의 호흡기로부터 배출되는 공기를 센싱하여 운전자의 알콜농도를 감지하는 것으로서, 이를 위해 운전자가 위치하는 운전석 주변에 설치되는 것이 바람직하며 본 발명의 실시예에서는 도 2에 도시된 바와 같이조향핸들(50) 전면상에 다수개가 설치된다.The breathalyzer sensor 10 senses the alcohol concentration of the driver by sensing the air discharged from the driver's respirator, for this purpose it is preferably installed around the driver's seat is located in Figure 2 in the embodiment of the present invention As shown, a plurality of steering wheels 50 are installed on the front surface.

이는 상기 조향핸들(50)이 운전석 바로 전방에 위치되므로 운전석에 위치하는 운전자의 호흡기로부터 배출되는 공기를 보다 효과적으로 수용하기 위함이다.This is because the steering wheel 50 is located directly in front of the driver's seat so as to more effectively receive the air discharged from the driver's respirator located in the driver's seat.

상기 음주측정센서(10)로부터 감지된 알콜농도는 A/D변환부(20)로 입력되어 디지털신호로 변환되고, 디지털 알콜농도 값은 계속해서 마이컴(30)에 제공된다.The alcohol concentration detected by the breathalyzer 10 is input to the A / D conversion unit 20 and converted into a digital signal, and the digital alcohol concentration value is continuously provided to the microcomputer 30.

상기 마이컴(30)은 입력된 알콜농도를 미리 입력된 허용기준치 알콜농도와 비교하게 되며 이를 위해 마이컴(30)의 내부에는 허용기준치 알콜농도가 입력되는 메모리부가 구비된다.The microcomputer 30 compares the input alcohol concentration with a previously input limit threshold alcohol concentration. For this purpose, the microcomputer 30 includes a memory unit for inputting the threshold threshold alcohol concentration.

그리고, 상기 마이컴(30)은 입력된 알콜농도와 허용기준치 알콜농도를 비교 분석한 뒤 그 결과에 따라 엔진의 시동여부를 결정하게 된다.Then, the microcomputer 30 compares the input alcohol concentration with the allowable reference alcohol concentration and determines whether to start the engine according to the result.

이때, 통상적으로 상기 마이컴(30)에서 비교 대상이 되는 허용기준치 알콜농도는 면허정지 및 벌금의 대상인 혈중알콜농도 0.05%가 바람직하다.At this time, in general, the allowable reference alcohol concentration to be compared in the microcomputer 30 is preferably a blood alcohol concentration of 0.05% of the license suspension and fines.

계속해서, 상기 마이컴(30)은 엔진제어부(40)에 구동신호를 선택적으로 인가함으로써 엔진제어부(40)가 엔진의 시동여부를 제어할 수 있도록 한다.Subsequently, the microcomputer 30 selectively applies a driving signal to the engine controller 40 so that the engine controller 40 can control whether the engine is started.

이때, 상기 엔진제어부(40)는 스타터모터에 전원을 선택적으로 공급함으로써 엔진의 시동여부를 제어할 수 있게 된다.In this case, the engine controller 40 may control whether the engine is started by selectively supplying power to the starter motor.

즉, 상기 마이컴(30)으로부터 구동신호가 인가되는 경우, 엔진제어부(40)는 스타터모터의 단자에 전원이 인가되도록 하고, 구동신호가 인가되지 않은 경우에는 스타터모터로 가는 전원이 차단되도록 함으로써 엔진의 시동여부를 제어하게 된다.That is, when a drive signal is applied from the microcomputer 30, the engine controller 40 causes the power to be applied to the terminal of the starter motor, and when the drive signal is not applied, the power to the starter motor is cut off. To control whether or not to start.

상기와 같은 구조로 이루어진 차량용 음주측정 장치를 이용한 음주측정 방법을 살펴보면 다음과 같다.Looking at the breath measurement method using a vehicle breathalyzer measuring device as described above are as follows.

도 3에 도시된 바와 같이, 먼저 차량의 조향핸들(50) 전면상에 설치된 음주측정센서(10)를 통해 운전자의 알콜농도를 감지하게 된다.(s10)As shown in FIG. 3, first, the alcohol concentration of the driver is detected through the breathalyzer 10 installed on the steering wheel 50 of the vehicle.

그리고, 마이컴(30)에서 상기 감지된 알콜농도를 토대로 엔진의 시동여부를 결정하게 되는데, 감지된 알콜농도가 허용기준치보다 높을 경우 마이컴은 엔진의 시동이 걸리지 않도록 엔진제어부에 구동신호를 발생하지 않게 되고, 허용기준치보다 낮을 경우에는 엔진의 시동이 걸리도록 엔진제어부에 구동신호를 발생하게 된다.(s20)The microcomputer 30 determines whether to start the engine based on the detected alcohol concentration. If the detected alcohol concentration is higher than the allowable reference value, the microcomputer does not generate a driving signal to the engine control unit so that the engine is not started. If it is lower than the allowable reference value, a driving signal is generated in the engine control unit so as to start the engine.

이와 같은 마이컴(30)의 결과, 즉 구동신호의 인가여부에 따라 엔진제어부(40)는 엔진의 시동여부를 제어하게 되는데, 구동신호 인가시에는 엔진의 시동이 걸리도록 하고, 구동신호가 없을 경우에는 엔진의 시동이 걸리지 않도록 제어하게 된다.(s30)As a result of the microcomputer 30, that is, whether the driving signal is applied, the engine control unit 40 controls whether the engine is started. When the driving signal is applied, the engine is started and when there is no driving signal. The engine is controlled so as not to be started. (S30)

상기한 바와 같이 본 발명에 따른 차량용 음주측정 장치 및 방법에 의하면, 운전자가 자동차를 운행하려고 할 경우 차량내부에 장착된 음주측정센서가 운전자의 호흡기로부터 배출되는 공기를 센싱하여 알콜농도를 감지하고, 운전자의 알콜농도가 법적 허용기준치를 초과할 경우 자동으로 자동차의 시동이 걸리지 않도록 함으로써 음주운전을 미연에 방지할 수 있도록 하는 효과가 있다.As described above, according to the in-vehicle breathalyzer measuring apparatus and method according to the present invention, when the driver tries to drive a car, a breathalyzer measuring sensor mounted on the inside of the vehicle senses the alcohol concentration by sensing the air discharged from the driver's respirator, When the driver's alcohol concentration exceeds the legal limit, the car is not automatically started so that drunk driving can be prevented.
