본 고안은 자동차의 후미 감시장치에 관한 것으로, 특히 차량의 후진시에만 동작하는 감시카메라와 모니터를 통해 차량의 후방을 확인할 수 있도록 한 자동차의 후방감시장치에 관한 것이다.The present invention relates to a rear monitoring device for a vehicle, and more particularly to a rear monitoring device for a vehicle to check the rear of the vehicle through a surveillance camera and a monitor that operates only when the vehicle reverses.

종래에는 차량을 후진시킬때 백미러 등을 통해 차량의 후방을 확인하면서 조작하였으므로 운전자가 내부백미러와 좌측백미러 및 우측백미러를 통해 간접적으로 보거나 고개를 뒤로 돌려서 직접 보게 되므로 올바른 운전자세를 이루지 못하여 자칫 잘못 조작하게 되는 단점이 있음은 물론, 아무리 잘 살핀다 하여도 볼 수 없는 사각지대가 있으므로 누군가의 안내를 받아야 하거나 위험부담을 안고 그냥 운전해야 하는 등의 문제점이 있었다.Conventionally, when the vehicle is reversed, the vehicle is operated while checking the rear of the vehicle through the rear view mirror, so that the driver views the vehicle indirectly through the internal rear view mirror, the left rear view mirror and the right rear view mirror, or turns the head backward to see the vehicle directly. There are disadvantages, of course, because there are blind spots that you can not see no matter how well you look at someone's guidance or had to drive with a risk.

그러므로 차량의 후진시 신호음을 울리거나 초음파 등을 통해 후방의 물체유무만 확인할 수 있도록 하였으나 운전자가 직접 확인할 수 없으므로 답답함을 가지게 되는 단점이 있었다.Therefore, it was possible to check the presence or absence of the rear object by sounding an ultrasonic signal or the like when the vehicle reversed, but the driver could not check it directly.

이에 따라 본 고안은 차량의 후진시에만 동작하는 감시카메라와 모니터로 후방을 확인하면서 조작할 수 있도록 한 자동차의 후방감시장치를 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a rear monitoring device for a vehicle that can be operated while checking the rear with a surveillance camera and a monitor that operate only when the vehicle reverses.

이와 같은 목적을 달성하기 위한 본 고안은 차량을 후진시키기 위해 후진기어를 넣으면 점등되는 후진등과 병렬로 접속하여 같이 동작하는 감시카메라로 후방의 넓은 범위를 촬영하고 이를 전기적인 신호로 바꾼 후, 운전자의 전방 적당한 위치에 설치한 모니터에 화상으로 재현시켜 줌으로써 운전자가 안정된 자세에서 후방을 확인하면서 후진시킬 수 있도록 한 것이다.In order to achieve the above object, the present invention is connected to the reverse light which is turned on when the reverse gear is put in order to reverse the vehicle. By reproducing the image on the monitor installed at the proper position in front of the driver, the driver can move backward while checking the rear in a stable position.

이하 본 고안을 첨부도면에 의거 상세히 기술하여 보면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

볼록렌즈(2)를 통해 후방의 넓은 범위의 피사체를 결상하는 감시카메라(1)와, 상기 감시카메라(1)의 색스포라이트필터(도면에 도시않음)에 결상된 적색신호(R)와 녹색신호(G) 및 파란색신호(B)에 대해 각각의 신호잡음비(SNUL)가 좋아지도록 하는 전치증폭기(Pre Amp)(3)(3a)(3b)와, 상기의 전치증폭기(3)(3a)(3b)를 경유한 색신호(R)(G)(B)를 조합하는 제1매트릭스회로(4)와, 상기의 제1매트릭스회로(4)를 경유한 중에 조합된 신호에 대해 휘도신호(Y)를 추출하는 제1필터(5)와, 상기 제1매트릭스회로(4)를 경유하는 중에 조합된 신호에 대해 색차신호(I)를 추출하는 제2필터(6)와, 상기의 제1매트릭스회로(4)를 경유하는 중에 조합된 신호에 대해 색차신호(Q)를 추출하는 제3필터(7)와, 상기 제1 내지 제3필터(5)~(7)로부터의 휘도신호(Y) 및 색차신호(I)(Q)를 혼합하여 선로를 통해 전송하는 영상출력부(8)와, 상기의 영상출력부(8)에서 선로를 통해 전달된 영상신호를 증폭하는 증폭부(9)와, 상기 증폭부(9)에서 증폭된 영상신호에 대해 삼원색의 색차신호(R-Y), (G-Y), (B-Y)를 분해해내는 제2매트릭스회로(10)와, 상기의 색차신호(R-Y), (G-Y), (B-Y)를 입력받아 운전자의 정면에 설치되는 모니터(12)의 화면에 화상으로 표현하는 CRT 구동부(11)들로 구성한다.Surveillance camera 1 for imaging a wide range of subjects in the rear through the convex lens 2, and red signal R and green formed in the color sprite filter (not shown) of the surveillance camera 1 Pre Amp (3) (3a) (3b) and the preamplifier (3) (3a) to improve the respective signal noise ratio (SNUL) for the signal (G) and the blue signal (B). The luminance signal Y is compared to the first matrix circuit 4 combining the color signals R, G, and B via (3b) and the signal combined while passing through the first matrix circuit 4 described above. ), A first filter (5) for extracting the?, A second filter (6) for extracting the color difference signal (I) with respect to the combined signal via the first matrix circuit (4), and the first matrix described above A third filter 7 which extracts the color difference signal Q with respect to the combined signal via the circuit 4, and the luminance signal Y from the first to third filters 5 to 7; And color difference signals (I) and (Q), Three primary colors for the image output unit 8 to be transmitted, the amplification unit 9 for amplifying the image signal transmitted through the line from the image output unit 8, and the image signal amplified by the amplification unit 9 The second matrix circuit 10 that decomposes the color difference signals RY, GY, and BY, and the color difference signals RY, GY, and BY are installed in front of the driver. It consists of CRT drive parts 11 which represent an image on the screen of the monitor 12 to be displayed.

그리고 내부의 요소들이 동기를 맞추기 위하여 동기신호발생기(13)에서는 감시카메라(1)의 1화면에 해당하는 신호들이 정확하게 전달되도록 동기신호를 출력하며, 자동차의 전원(12V, 24V)을 입력받아 동작전원으로 변환시켜 내부의 회로에 공급하는 전원부(14)에서는 후진등으로 전달되는 전원을 공급받아 후진시에만 동작하도록 한 것이다.In order to synchronize the internal elements, the synchronization signal generator 13 outputs a synchronization signal so that signals corresponding to one screen of the surveillance camera 1 are correctly transmitted, and is operated by receiving power of the vehicle (12V, 24V). The power supply unit 14, which is converted into a power source and supplied to an internal circuit, receives only the power delivered to the reverse light and operates only in reverse.

이와 같이 구성한 본 고안의 자동차의 후방 감시장치는 운전자가 차량을 후진시키기 위해 후진기어를 넣으면 자동으로 후진등에 공급되어 점등되도록 하는 전원을 전원부(13)로도 공급받아 후진시에만 동작하도록 한 것으로서, 볼록렌즈(2)를 통하여 사각지대가 없는 넓은 범위를 한번에 촬영할 수 있는 감시카메라(1)에서 피사체를 촬영하면 내부의 색스포라이트 필터(또는 촬상관)에 결상된 적색신호(R)와 녹색신호(G) 및 파란색신호(B)를 각각 전치증폭기(3)(3a)(3b)를 경유하도록 하여 신호대 잡음비가 좋아지도록 한 후, 제1매트릭스회로(4)에서 조합하여 제1필터(5)와 제2필터(6) 및 제3필터(7)를 각각 경유하도록 한다.The rear monitoring device of the present invention configured as described above is operated by the power supply unit 13 so that the driver is automatically supplied to the reverse light when the driver puts the reverse gear in order to reverse the vehicle. When the subject is photographed by the surveillance camera 1 capable of capturing a wide range without blind spots through the lens 2 at once, the red signal R and the green signal G formed in the internal color sprite filter (or image tube) are captured. ) And the blue signal (B) are passed through the preamplifiers (3) (3a) and (3b), respectively, so that the signal-to-noise ratio is improved, and then the first matrix 5 and the first filter 5 Via the second filter 6 and the third filter 7, respectively.

상기의 제1필터(5)와 제2필터(6) 및 제3필터(7)를 경유하는 중에 각각 추출되는 휘도신호(Y)와 색차신호(I)(Q)를 영상출력부(8)에서 호합하여 전선을 통하여 차량의 앞쪽으로 보낸다.The image output unit 8 outputs the luminance signal Y and the color difference signal I and Q respectively extracted while passing through the first filter 5, the second filter 6, and the third filter 7. And then forward through the wire to the front of the vehicle.

전선을 통해 입력되는 휘도신호(Y)와 색차신호(I)(Q)를 증폭부(9)에서 충분히 증폭하면, 증폭된 신호를 입력받는 제2매트릭스회로(10)에서 색차신호(R-Y), (G-Y), (B-Y)로 분해하여 CRT구동부(11)로 전송하고, CRT구동부(11)에서는 동기신호 발생기(13)의 동기신호에 따라 화면상에 해당하는 색차신호로서 모니터(12)에 화상을 형성한다.When the amplification unit 9 sufficiently amplifies the luminance signal Y and the color difference signal I and Q input through the wire, the color difference signal RY in the second matrix circuit 10 receiving the amplified signal, (GY) and (BY) are decomposed to the CRT driver 11, and the CRT driver 11 displays an image on the monitor 12 as a color difference signal corresponding to the screen according to the synchronization signal of the synchronization signal generator 13. To form.

따라서 본 고안의 자동차의 후방감시장치에 의하여서는 차량의 후방에 설치되는 감시카메라가 후진기어에 의해 점등하는 후진등과 같이 동작하도록 하고, 볼록렌즈를 통해 넓은 범위의 피사체를 촬영하여 운전자의 전방에 설치한 모니터를 통해 확인할 수 있도록 함으로써, 운전자가 차량을 후진시킬 때 안정된 자세에서 정확한 조작을 할 수 있으므로 후진에 자신이 없었던 사람들이 효율적으로 이용할 수 있는 것이다.Therefore, by the rear surveillance device of the present invention, the surveillance camera installed in the rear of the vehicle operates like a reverse light that is turned on by the reverse gear, and shoots a wide range of subjects through the convex lens to the front of the driver. By enabling the monitor to be installed, the driver can operate the vehicle in a stable position when the driver reverses the vehicle, so that people who were not confident in the reverse can use it efficiently.
