여기에서 참조되는 바와 같이 본 발명은 광원이 발생되는 제 1 발광부(10)가 설치되어 있고, 그 제 1 발광부(10)의 근접된 위치에는 제 1 발광부(10)에서 발생된 후 물체에 반사되는 빛을 수광하는 제 1 수광부(11)가 설치되어 있다.As referred to herein, the first light emitting unit 10 in which the light source is generated is provided, and the object after being generated in the first light emitting unit 10 is located near the first light emitting unit 10. The first light receiving portion 11 for receiving the light reflected by the light is provided.

그리고 또 다른 광원이 발생되는 제 2 발광부(20)가 설치되어 있고, 그 제 2 발광부(20)의 근접된 위치에는 제 2 발광부(20)에서 발생된 후 물체에 반사되는 빛을 수광하는 제 2 수광부(21)가 설치되어 있다.In addition, a second light emitting unit 20 is formed to generate another light source, and the light emitted from the second light emitting unit 20 and then reflected by an object is received at a position adjacent to the second light emitting unit 20. The second light receiving portion 21 is provided.

한편, 상기 제 1 수광부(11) 및 제 2 수광부(21)에는 수광되는 빛의 양을 거 리로 연산하고 설정된 거리와 연산된 거리를 비교한 후 오디오 장치를 동작시키는 제어신호가 발생되는 제어부(30)가 연결되어 있다.On the other hand, the first light receiving unit 11 and the second light receiving unit 21 is a control unit 30 that calculates the amount of light received by a distance, compares the set distance and the calculated distance and then generates a control signal for operating the audio device ) Is connected.

그리고, 상기 제 1 수광부(11)에 수광되는 빛의 양에 따라서 연산된 거리는 오디오 장치를 온, 채널 업 선택 및 채널 다운 동작을 위한 입력값으로 사용되고, 상기 제 2 수광부(21)에 수광되는 빛의 양에 따라서 연산된 거리는 오디오 장치를 오프, 볼륨 업 및 볼륨 다운 동작을 위한 입력값으로 사용된다.The distance calculated according to the amount of light received by the first light receiver 11 is used as an input value for turning on, channel up selection and channel down the audio device, and the light received by the second light receiver 21. The calculated distance is used as an input for the audio device off, volume up and volume down operations.

또한, 상기 제어부(30)에는 그 제어부(30)에서 발생되는 제어신호를 아나로그 값으로 변환하는 DA컨버터(40)가 연결되어 있고, 상기 DA컨버터(40)에는 그 DA컨버터(40)의 출력값에 따라서 동작되는 오디오 장치(50)가 연결되어 있다.In addition, the control unit 30 is connected to a DA converter 40 for converting a control signal generated by the control unit 30 to an analog value, and the output value of the DA converter 40 is connected to the DA converter 40. The audio device 50 which operates according to this is connected.

이와 같이 구성된 본 발명의 작동상태를 상세히 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described in detail as follows.

먼저, 차량에 설치된 오디오 장치에 전원을 공급하면 차량 상황(차량 내부의 평균적인 빛의 양 등)을 측정하여 제어부(30)로 전송함과 동시에 제 1 발광부(10) 및 제 2 발광부(20)에서 광원이 발생되는 것이며, 상기 광원에 물체(사용자의 손)가 근접되지 않을 경우에는 반사되지 않고 물체가 근접될 경우에는 반사되어 수광부로 입력되며 수광되는 빛의 양을 차량 상황의 측정값에 따라서, 변경되게 된다.First, when power is supplied to the audio device installed in the vehicle, the vehicle situation (average amount of light in the vehicle, etc.) is measured and transmitted to the control unit 30, and at the same time, the first light emitting unit 10 and the second light emitting unit ( 20) a light source is generated, and when the object (user's hand) is not close to the light source, it is not reflected, and when the object is close, it is reflected and input to the light receiving unit, and the amount of light received is measured value of the vehicle situation. As a result, it is changed.

즉, 차량의 내부에 빛이 많을 경우와 빛이 적을 경우에 각각 측정된 차량 상황에 따라서 제어부(30)에서는 수광되는 빛의 양을 각각 연산하게 된다.That is, the controller 30 calculates the amount of light received according to the vehicle situation measured when there is much light and when there is little light in the interior of the vehicle.

따라서, 제 1 수광부(11)에 빛이 수광되면, 오디오 장치를 온 시키고 수광되는 빛은 제어부(30)로 전송된 후 거리값으로 연산되고, 그 연산된 거리가 채널 업 설정거리 이내인가를 확인하여 채널 업 설정거리 이내이면 채널을 업(높은 주파수 로 이동되면서 방송주파수를 찾는다)하게된다.Therefore, when light is received by the first light receiving unit 11, the audio device is turned on and the received light is transmitted to the controller 30 and then calculated as a distance value, and it is checked whether the calculated distance is within the channel up setting distance. If the channel up is within the set distance, the channel is turned up (find the broadcasting frequency while moving to the higher frequency).

상기 연산된 거리가 채널 업 설정이내가 아닐 경우에는 연산된 거리가 채널 다운 거리 이내인가를 확인하여 채널 다운 설정거리 이내이면 채널을 다운(낮은 주파수로 이동되면서 방송주파수를 찾는다)하게 되고 채널 다운 설정거리 이내가 아닐 경우에는 채널을 조절할 수 있는 조건에 해당되지 않게되므로 수광되는 빗을 거리로 연산하여 채널 조절을 연속적으로 수행하게 된다.If the calculated distance is not within the channel up setting, it is checked whether the calculated distance is within the channel down distance. If the calculated distance is within the channel down setting distance, the channel is down (the broadcast frequency is searched while moving to a lower frequency). If it is not within the distance does not correspond to the conditions for adjusting the channel, the channel adjustment is continuously performed by calculating the received comb as a distance.

그리고 상기 제 1 수광부(11)에 빛이 수광되지 않을 경우에는 제 2 수광부(21)에 빗의 수광 상태를 확인하여 수광되지 않을 경우에는 물체가 근접되지 않을 상태이므로 대기하게 되고, 제 2 수광부(21)에 빛이 수광되면 수과외는 빛을 거리로 연산한다. When the light is not received by the first light receiver 11, the light receiver of the comb is checked by the second light receiver 21. When the light is not received by the comb, the object is not in proximity to the second light receiver. When light is received in 21), the extracurricular tutor calculates the light as distance.

상기 연산된 거리가 볼륨 업 설정거리 이내인가일 경우에는 볼륨을 업시키게 되고, 연산된 거리가 볼륨 업 설정거리 이내가 아닐 경우에는 연산된 거리가 볼륨 다운 거리 이내인 가를 확인하게 되며, 연산된 거리가 볼륨다운 거리 이내이면 볼륨을 다운시키고, 연산된 거리가 볼륨다운 거리 이내가 아닐 경우에는 오디오를 오프시키게 되는 것이다.When the calculated distance is within the volume up setting distance, the volume is turned up. When the calculated distance is not within the volume up setting distance, the calculated distance is checked to be within the volume down distance. If is within the volume down distance, the volume is turned down. If the calculated distance is not within the volume down distance, the audio is turned off.

이와 같이 본 발명은 차량에 설치된 오디오 장치를 접촉하지 않고도 물체(사용자의 손)가 근접되는 거리에 따라서 오디오 장치의 온/오프 및 채널/볼륨의 업/다운 동작이 수행되므로 오디오 장치의 동작으로 인한 운전자의 집중력 저하를 미연에 방지할 수 있게되는 특유의 효과가 있다.As described above, according to the present invention, since the on / off operation of the audio device and the up / down operation of the channel / volume are performed according to the distance of the object (the user's hand) without touching the audio device installed in the vehicle, There is a distinctive effect that can prevent the driver's concentration loss in advance.
