본 고안은 자동차용 알콜감지 제어장치에 관한 것으로서, 특히 자동차의 운전석과 근접한 위치에 알콜 농도를 감지하는 센서를 부착시켜서 운전자가 일정한 알콜 농도 이상에서 운전하여야 할때 주의 운전이나 운전불능경고 그리고, 운전 불능 상태를 알려주고, 자동차를 제어할 수 있도록 한 것에 주안점을 둔 것이다.The present invention relates to an alcohol sensor for automobiles, in particular, by attaching a sensor that detects the alcohol concentration in a position close to the driver's seat of the vehicle, when the driver must drive above a certain alcohol concentration warning and driving failure, and driving The main focus was on notifying the disabled state and allowing the car to be controlled.

일반적으로 자동차는 사람들의 교통수단에 지대한 기여를 하지만 음주운전시에는 운전자의 반사신경이 늦기때문에 핸들의 회전속도나, 브레이크의 페달을 밟는 속도가 늦게 됨에 따라 사고의 위험을 내포하게 된다.In general, automobiles make a significant contribution to people's means of transportation, but when driving drunk, the reflexes of the driver are slow, so the rotation speed of the steering wheel and the pedaling speed of the brakes are slowed.

따라서, 운전자의 음주운전 여부를 체크하고 감독하기 위해서 도로순찰자가 알콜농도 측정기를 이용하여 운행중인 차량을 정차시켜서 운전자의 알콜농도를 체크하게 되는데, 이는 번잡한 도로상에서 차량을 정차시켜 체크함에 따라 교통체증을 더욱 증가시키게 되는 문제점을 가지게 됨은 물론이고, 도로순찰자가 알콜측정기로서 운전자의 음주운전을 단속하는것 만으로는 음주운전을 완전하게 단속할 수 없게 된다.Therefore, in order to check and supervise the driver's drunk driving, the road patrolman stops the vehicle in operation by using the alcohol concentration meter to check the alcohol level of the driver. Not only will there be a problem of increasing the traffic jam, but also the road patrols can not completely crack down on drunk driving just by controlling the driver's drunk driving as an alcohol meter.

그러므로서 음주운전에 따른 사고가 발생하여 인명사고나 차량등의 재산손실을 가져오는 문제점을 가지고 있었다.Therefore, the accidents caused by drunk driving caused a problem of property loss, such as life-savings and vehicles.

본 고안은 상기와 같은 문제점을 좀더 완벽하게 해결하여 음주운전에 따른 사고를 방지할 수 있도록 한 것으로서, 자동차 운전석의 근접한 위치에 알콜 농도를 감지하는 센서를 부착시키고, 이 알콜농도에 따라서 운전자에게 현재 운전자가 주의하여 운전을 하여야 할 정도 그리고 현재는 운전을 할수 없는 완전히 운전 불능상태를 디스플레이하여 주도록 한다.The present invention is to solve the above problems more completely to prevent accidents caused by drunk driving, to attach a sensor to detect the alcohol concentration in the vicinity of the driver's seat, according to the alcohol concentration present to the driver The driver should be cautious to drive and display a completely disabled state that cannot be driven at present.

그리고, 상기 알콜농도에 따라서 자동차를 제어할 수 있게함으로서, 음주운전에 따른 사고를 미연에 방지할 수 있게 한것에 주목적으로 둔 것이다.In addition, by controlling the vehicle according to the alcohol concentration, the main purpose is to prevent accidents due to drunk driving in advance.

이하 첨부 도면에 따라서 상세히 설명하면 다음과 같다.Hereinafter, a detailed description will be given with reference to the accompanying drawings.

제1도와 같이 알콜농도를 쉽게 감지하도록 팬블로우를 가진 알콜감지기(1)와 차내의 온도를 감지하는 온도감지기(2) 및 운전석 도어 열림여부 감지기(3)의 출력을 1차 비교기(4)에 연결하고 이 비교기(4)의 출력은 A/D 컨버터(5)를 거쳐 2차 비교기(7)에 연결한다.As shown in FIG. 1, the outputs of the alcohol detector 1 having a fan blow, the temperature sensor 2 detecting the temperature inside the vehicle, and the driver's door opening detector 3 are easily output to the primary comparator 4 to detect the alcohol concentration. The output of this comparator 4 is connected to the secondary comparator 7 via an A / D converter 5.

상기 A/D 컨버터(5)의 출력은 알콜농도 및 주의사항을 디스플레이하고 주의를 알리는 경보기(6)에 연결하고, 상기 2차 비교기(5)의 출력은 운전가능 상태 표시 및 주의운전 표시램프(8)와 운전불능 경고램프(9) 그리고, 운전불능 경고시 뒷 유리창 도로가장자리로 피양협조 점멸 램프(10)와 자동차 메인 전원 스위칭 릴레이(11)를 연결하여서 된 것이다.The output of the A / D converter 5 is connected to the alarm 6 for displaying the alcohol concentration and the precaution and informing the precaution, and the output of the secondary comparator 5 is the operational status indication and the caution operation indicator lamp ( 8) and the non-operation warning lamp (9), and in the event of a non-operation warning by connecting the flickering cooperation lamp 10 and the vehicle main power switching relay 11 to the edge of the rear window.

상기에서 각 감지기(1), (2)는 운전석의 가장 근접한 소정위치에 부착 설치 하는것이 이상적이다.Each detector (1), (2) is ideally attached to the predetermined position of the driver's seat.

제2도는 본 발명의 시스템을 40㎝ 떨어진 핸들부위에 설치한후 실험한 알콜농도에 따른 증폭기 출력 전압을 그래핑한 것이다.Figure 2 is a graph of the amplifier output voltage according to the alcohol concentration tested after the system of the present invention is installed on the handle portion 40 cm away.

제2도에 나타난 데이타는 필요에 따라서 원하는 소정 위치에 설치하여 바이어스 값을 조정할 수 있다.The data shown in FIG. 2 can be installed at a desired predetermined position as needed to adjust the bias value.

이와같은 구성으로 형성된 본 고안의 동작 및 작용 효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention formed in such a configuration as follows.

우선, 음주운전자가 차내에 들어오게되면, 차내 운전석과 가장 근접한 위치에 설치된 감지기(1), (2), (3)는 일제히 모든 감지를 시작한다.First, when a drunk driver enters a vehicle, the detectors 1, 2, and 3 installed in the closest position to the driver's seat start all detection simultaneously.

이때, 운전자의 호흡을 세밀하게 감지하기 위한 소형 블로우 팬 내부에 설치된 알콜감지기(1)는 음주정도를 감지하고, 음주정도 감지에 미치는 온도 및 외부공기 유입에 따르는 영향을 보상하기위한 온도 감지기(2) 및 운전석 도어 열림여부 감지기(3)도 동작한다.At this time, the alcohol detector (1) installed inside the small blow fan for finely detecting the driver's breathing is a temperature sensor (2) to detect the degree of drinking, and to compensate for the effects of temperature and external air influx on the level of drinking ) And the driver's door open / close detector 3 also operate.

각 감지된 신호는 1차 비교기(4)에 입력된다.Each sensed signal is input to a primary comparator 4.

1차 비교기(4)에서는 제2도의 출력 신호 데이타에 대비하여 온도값을 계산하고, 감지기(1)의 감지신호가 온도에 영향을 받은만큼 가산 혹은 감산하여 온도의 영향에 관계없이 일정한 결과를 얻게하고, 또한 도어 열림감지기(3)의 신호도 역시 도어가 열려 외기의 유입이 있었을 경우 제2도의 출력에 대비하여 도어를 열었을때 발생된 영향만큼의 순바이어스를 걸게 된다.The primary comparator 4 calculates the temperature value against the output signal data of FIG. 2 and adds or subtracts the detected signal of the detector 1 as much as it is influenced by temperature to obtain a constant result regardless of the influence of temperature. In addition, the signal of the door open detector 3 also applies a forward bias as much as the effect generated when the door is opened in preparation for the output of FIG.

1차 비교기에서 출력된 아날로그 신호는 A/D 컨버터(5)를 거치게 된다. A/D 컨버터(5)는 입력된 아날로그신호를 디지탈 신호로 변환한 다음 2차 비교기와 알콜 농도 및 주의 상황 표시용 디스플레이 및 경보기(6)로 입력된다.The analog signal output from the primary comparator passes through the A / D converter 5. The A / D converter 5 converts the input analog signal into a digital signal and then inputs it to the secondary comparator, the alcohol concentration and the caution display and the alarm 6.

2차 비교기(7)에서는 A/D 컨버터의 디지탈 신호를 기 설정된 기준 데이타에 의하여 단계별로, 운전가능신호와 주의운전 신호는 상태표시램프(8)에 표시되게 하고, 운전불능 신호는 운전불능 경고 표시램프(9)에 표시하게하여, 피양협조 신호는 피양협조 램프(10)에 표시하게 한다.In the secondary comparator 7, the digital signal of the A / D converter is displayed step by step according to the preset reference data, and the operation enable signal and the caution operation signal are displayed on the status display lamp 8, and the operation disable signal warns the operation failure. Displayed on the display lamp 9 causes the coordinated signal to be displayed on the coordinated lamp 10.

또한, 메인전원 스위칭 릴레이 신호모드는 자동차의 메인전원 스위칭 릴레이(11)에서 조건에 따라 온, 오프되게 한다.In addition, the main power switching relay signal mode is turned on and off according to the conditions in the main power switching relay 11 of the vehicle.

이와같은 각 신호모드에 따른 지시장치의 동작전에 LCD 또는 LED 세그먼트를 사용하여 만든 알콜농도 및 주의사항 디스플레이 및 경보기(6)가 동작된다.Before operation of the indicator according to each signal mode, the alcohol concentration and caution display and alarm 6 made by using the LCD or LED segment are operated.

디스플레이는 단계적 상황에 따라 감지되는 알콜의 농도를 숫자 및 그래프로 표시하고, 오디오 IC로 된 경보기는 각 단계적 상황을 소리로서 알려주며 특히, 운전불능시는 1분후에 운전이 중지된다는 내용을 반복적으로 알려 준다.The display shows the level of alcohol detected in steps and numbers in a graph and an audio IC alarm alerts each step as a sound. In particular, the display is repeatedly informed that operation is stopped after one minute. give.

상기 각 신호모드에 따른 지시장치의 동작상태 및 기능을 실시예에 따라 설명하겠다.An operation state and a function of the indicating device according to each signal mode will be described according to embodiments.

The lamp lights up.

둘째, 운전불능 경고램프(9)는 제2도에 나타난 감지출력 전압이 9V 범위 즉, 기준치 이상의 알콜농도가 감지되었을때 작동되며, 운전석 전면에 주의 운전 신호램프와 동일한 크기의 빨강색조 램프에 1분동안 깜박여 운전자로 하여금 도로우측으로 피양해야 함을 알린다.Second, the non-operation warning lamp 9 is activated when the detection output voltage shown in FIG. 2 is in the range of 9 V, that is, the alcohol concentration above the reference value is detected. Flashes for a minute to let the driver know that the road should be turned to the right.

이 램프는 1분후에 메인파워가 멈춰지면서 깜박거림을 멈춘다.This lamp will stop blinking after 1 minute of main power stop.

셋째, 피양협조 램프(10)는 운전 불능 경고램프의 작동과 동시에 작동되며, 주행중인 다른 차량에게 음주운전 차량임을 알리고 협조를 얻도록 뒷유리창 우측 상단부에 설치되어 있다.Third, the fostered coordination lamp 10 is operated at the same time as the operation of the inoperable warning lamp, and is installed on the upper right side of the rear window so as to inform other driving vehicles that are drunk driving vehicles and obtain cooperation.

이 램프는 주기적으로 점멸되는 적색램프로서 열쇠를 차에서 탈거하여야 램프가 소등이 된다.This lamp is a red lamp that blinks periodically so that the lamp will not turn off until the key is removed from the car.

넷째, 메인파워 스위칭 릴레이(11)는 음주량이 운전불능에 이르면 운전불능 램프가 켜지는 순간부터 1분후에 릴레이가 동작하여 라디오, 미등, 방향지시 등을 제외한 전 전원을 차단시키며 차에서 열쇠를 탈거하면 자동해체 된다.Fourth, the main power switching relay 11 operates the relay after 1 minute from the moment when the inoperable lamp is turned on when the amount of alcohol drinking is inoperable and cuts off all the power except the radio, taillight, direction indicator, etc. Is automatically disassembled.

이와같이 본 고안의 자동차 알콜농도 감지 제어장치는 알콜농도 감지기와 온도감지기 그리고 도어 열림감지기를 자동차에 부착시켜서 운전자의 알콜농도에 따라서 각 운전 상태인 운전가능, 주의운전 그리고 운전불능상태를 알려줌과 동시에 자동차의 메인전원을 제어하도록 하므로서, 음주운전에 따른 사고를 미연에 방지 할수 있게된 유용한 것이다.In this way, the vehicle alcohol concentration control device of the present invention attaches an alcohol concentration sensor, a temperature sensor, and a door open detector to the car to inform the driver of the driving condition, driving and disabling conditions according to the alcohol concentration of the driver. By controlling the main power of the, it will be useful to prevent accidents caused by drunk driving in advance.
