위와 같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

우선, 음주를 한 차량운전자가 차량을 운행하기 위해 차량의 운전석시트(도시되지 않음)에 착석하게 되면 차량의 밧데리전원(1)으로부터 소정 전류를 인가받은 압력센서(2)가 작동되게 된다.First, when a drunk vehicle driver is seated on a driver's seat (not shown) of a vehicle to drive a vehicle, the pressure sensor 2 applied with a predetermined current from the battery power source 1 of the vehicle is operated.

또한, 상기 압력센서(2)가 작동되면 소정의 전기신호가 출력되게 되는데 이때, 출력된 전기신호는 차량용 썬바이저(도시되지 않음)의 일측 소정부위에 구비되는 알콜농도측정센서(3)에 인가되게 되고 그에 따라 상기 알콜농도측정센서(3)가 차량운전자의 알콜농도를 측정하게 된다.In addition, when the pressure sensor 2 is operated, a predetermined electric signal is output. In this case, the output electric signal is applied to the alcohol concentration sensor 3 provided at one side of a vehicle sun visor (not shown). Accordingly, the alcohol concentration sensor 3 measures the alcohol concentration of the vehicle driver.

또한, 상기 알콜농도측정센서(3)는 차량운전자의 알콜농도를 측정한 후 비교회로(4)에 측정데이타를 인가시키게 되는데 이때, 상기 비교회로(4)는 측정데이타값이 규정치 이상이 되는지를 판단하게 된다.In addition, the alcohol concentration sensor 3 measures the alcohol concentration of the vehicle driver and then applies the measurement data to the comparison circuit 4, where the comparison circuit 4 determines whether the measured data value is equal to or greater than a prescribed value. You will be judged.

즉, 상기 비교회로(4)는 상기 알콜농도측정센서(3)로부터 인가받은 측정데이타값이 규정치 이상이라고 판단되면 상기 비교회로(4)에 전기적으로 연결되는 릴레이(5)에 제어신호를 보내 상기 릴레이(5)의 접속단자를 접속시키게 되는데 이때, 상기 릴레이(5)에 전기적으로 연결되는 경고용 램프(6)가 점등됨과 동시에 경고용 벨(7)이 울리게 된다.That is, the comparison circuit 4 sends a control signal to the relay 5 electrically connected to the comparison circuit 4 when it is determined that the measured data value applied from the alcohol concentration sensor 3 is equal to or greater than the prescribed value. When the connection terminal of the relay 5 is connected, the warning lamp 6 electrically connected to the relay 5 is turned on and the warning bell 7 rings.

또한, 이때 상기 밧데리전원(1)으로부터 공급되는 전류가 모두 상기 릴레이(5)쪽으로 흐르게 되어 차량의 시동스위치(9)는 오프(OFF)상태로 된다.At this time, all of the current supplied from the battery power source 1 flows toward the relay 5, so that the start switch 9 of the vehicle is turned off.

한편, 상기 알콜농도측정센서(3)로부터 인가받은 측정데이타값이 규정치 미만이라고 판단되면 상기 릴레이(5)에 소정의 제어신호를 보내고 그에 따라 상기 릴레이(5)의 접속단자가 끊어지게 되는데 이때, 상기 릴레이(5)쪽으로 흐르던 전류가 트랜지스터(8)의 베이스단자에 인가되게 된다.On the other hand, if it is determined that the measured data value applied from the alcohol concentration sensor 3 is less than the prescribed value and sends a predetermined control signal to the relay 5, the connection terminal of the relay 5 is cut accordingly, The current flowing toward the relay 5 is applied to the base terminal of the transistor 8.

또한, 상기 트랜지스터(8)의 베이스에 전류가 인가되게 되면 상기 트랜지스터(8)가 도통되게 되는데 이에 따라서 상기 시동스위치(9)가 온(ON)되게 된다.In addition, when a current is applied to the base of the transistor 8, the transistor 8 is turned on so that the start switch 9 is turned on.

특히, 상기 각 소자들 사이에는 저항R1∼R6이 전기적으로 연결되어 상기 각각의 소자에 흐르는 전류의 세기를 제어하게 된다.In particular, the resistors R1 to R6 are electrically connected between the respective devices to control the strength of the current flowing through the respective devices.

위와같이, 본 발명에 의한 차량의 음주운전방지회로는 차량의 운전석시트(도시되지 않음)의 일측 소정부위에 압력센서(2)를 구비함과 더불어 상기 압력센서(2)로부터 소정의 전기신호를 인가받아 작동되는 알콜농도측정센서(3)를 구비하여 차량의 운전자가 상기 운전석시트에 착석하게 되면 상기 압력센서(2)로부터 전기신호를 인가받은 상기 알콜농도측정센서(3)에 의해 차량운전자의 알콜농도가 측정된 후 측정된 알콜농도가 규정치 이상이 되면 자동으로 차량실내에 구비되는 경고용 램프(6) 및 경고용 벨(7)이 작동됨과 더불어 차량의 밧데리전원(1)이 차단되게 되어 차량의 시동이 걸리지 않게 됨으로써 차량운전자의 음주운전을 방지할 수 있게 되는 효과가 있다.As described above, the drunk driving prevention circuit of the vehicle according to the present invention includes a pressure sensor 2 at a predetermined portion of one side of a driver's seat (not shown) of the vehicle and at the same time receives a predetermined electric signal from the pressure sensor 2. When the driver of the vehicle is seated on the driver's seat with an alcohol concentration measuring sensor 3 that is activated and operated, the alcohol concentration measuring sensor 3 receives an electric signal from the pressure sensor 2. If the measured alcohol concentration exceeds the prescribed value after the alcohol concentration is measured, the warning lamp 6 and the warning bell 7 provided in the vehicle interior are automatically activated and the battery power source 1 of the vehicle is cut off. By not starting the vehicle there is an effect that can prevent the drunk driving of the vehicle driver.
