본 발명은 차량의 후방 영상경보장치에 관한 것으로, 특히 차량의 후진시에 전원이 공급되는 후진등의 전원선을 이용하여 차량의 후방을 감시하는 감시카메라와 감지센서에 전원을 공급함과 더불어 후방영상 및 감지센서의 감지데이터를 별도의 선로 없이 자체 전원선을 이용해 주고받도록 한 차량의 자체 전원선을 이용한 후방 영상경보장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear image alarm device for a vehicle. In particular, the rear image image is supplied with power to a surveillance camera and a sensing sensor for monitoring the rear of the vehicle by using a power line such as a reverse light that is powered when the vehicle is reversed. And a rear image alarm device using its own power line to transmit and receive sensing data of a sensor using its own power line without a separate line.

일반적으로 차량의 리어 범퍼에는 차량 후방의 장애물을 감지하는 초음파센서와 같은 후방감지센서가 설치되어 운전자의 후진을 돕고 있다.    In general, a rear detection sensor such as an ultrasonic sensor for detecting an obstacle behind the vehicle is installed in the rear bumper of the vehicle to help the driver reverse.

그러나 차량 출고시 후방감지센서가 장착된 차량도 있으나, 차량 출고 후 필요에 따라 후방감지센서를 설치할 경우, 차량의 중앙경보장치와 후방감지센서의 연결을 위한 별도의 신호선을 설치하여야 하며, 특히 컨테이너 차량이나 대형 버스 등 후방시야 확보가 어려운 차량의 경우 별도의 감시카메라와 모니터를 전용 케이블을 사용하여 설치하는바 이는 신호선의 연결을 위해 차체를 분리해야하는 등의 복잡한 작업을 병행하여야만 하는 불편을 초래하였다.However, some vehicles are equipped with a rear sensor when the vehicle is shipped. However, when the rear sensor is installed as needed after the vehicle is shipped, a separate signal line for connecting the central alarm device and the rear sensor of the vehicle should be installed. In case of a vehicle or a large bus, it is inconvenient to install a separate surveillance camera and monitor by using a dedicated cable, which requires complicated tasks such as detaching the car body to connect signal lines. .

이에 따라 일부 차량의 경우 후방 감시카메라 및 감지센서와 차량의 중앙경보기 또는 모니터가 무선으로 신호를 주고받도록 한 경우도 있으나, 이 경우 신호 간 간섭이나 다수의 차량이 있을 때 오동작의 우려가 빈번했다.Accordingly, in some vehicles, the rear surveillance camera and the sensor and the central alarm or monitor of the vehicle may transmit or receive signals wirelessly, but in this case, interference between signals or malfunctions are frequently occurred when there are a large number of vehicles.

따라서 본 발명은 이러한 점을 감안한 것으로, 본 발명은 차량의 후방감시를 위한 감시카메라 및 감지센서의 연결을 위한 별도의 신호선을 설치하지 않고도 차량의 후진시에 전원이 공급되는 후진등의 전원선을 이용하거나, 차량에 배선된 기존의 전원선을 이용하여 간단히 감시카메라와 감지센서에 전원을 공급함과 더불어 이들에 의해 얻어지는 영상 및 데이터를 자체 전원선을 통해 전송 및 수신할 수 있도록 한 차량의 자체 전원선을 이용한 후방 영상경보장치를 제공함에 그 목적이 있다.
Accordingly, the present invention has been made in view of the above, and the present invention provides a power line such as a reverse light supplying power when the vehicle is reversed without installing a separate signal line for connecting a surveillance camera and a sensor for rear monitoring of the vehicle. Power supply to surveillance camera and sensor by using existing power line that is wired to the vehicle or by using the existing power line of the vehicle, and the vehicle's own power that can transmit and receive the image and data obtained through them through its own power line. The purpose is to provide a rear image alarm device using a line.

Is sent.

이와 같이 전원선(300)을 통해 후방 영상 경보부(200)측으로 전송된 영상 및 감지데이터는 차량 시거잭(500)의 전원선(600)를 통해 후방 영상 경보부(200)측으로 전송되게 되는 것으로, 후진등(400)의 전원선(300)과 차량 시거잭(500)의 전원 선(600)은 차량 내에서 서로 연결된 구조로 되어 후방감지부(100)로부터의 영상 및 감지데이터가 후방 영상 경보부(200)측으로 전송될 수 있게 되는 것이다.As such, the image and the sensing data transmitted to the rear image alarm unit 200 through the power line 300 are transmitted to the rear image alarm unit 200 through the power line 600 of the vehicle cigar jack 500. The power line 300 of 400 and the power line 600 of the vehicle cigar jack 500 are connected to each other in the vehicle such that the image and the sensing data from the rear sensing unit 100 are directed to the rear image alarm unit 200. It can be transmitted.

상기 후방감지부(100)에서 전송된 영상 및 감지데이터는 전원선(300),(600)을 통해 각각 고주파 필터(201),(211)를 통해 추출되어 비디오 RF증폭부(203)와 데이터 RF증폭부(213)에서 증폭된 후, 비디오 FM복조부(205)와 데이터 FM복조부(215)에서 각각 FM복조된다.The image and the sensing data transmitted from the rear sensing unit 100 are extracted through the high frequency filters 201 and 211 through the power lines 300 and 600, respectively, and the video RF amplifier 203 and the data RF are extracted. After amplifying by the amplifier 213, FM demodulation is performed by the video FM demodulator 205 and the data FM demodulator 215, respectively.

It is.

이러한 본 발명은 필요에 따라, 복수의 감시카메라와 감지센서를 설치할 수도 있으며, 이 경우 복수의 반송파로 각각 변조 및 복조하여 다수의 영상이나 데이터를 전송 및 수신할 있도록 광대역 RF대역의 신호로 만들어진다.The present invention may be provided with a plurality of surveillance cameras and sensors, if necessary, in this case is made of a signal of a wideband RF band so as to transmit and receive a plurality of images or data by modulating and demodulating with a plurality of carriers, respectively.

또한, 상기 감시카메라(101)를 차량의 후방뿐만 아니라, 전원선만 연결해서 좌우측방의 필요부위에 다수개 설치할 수 있으며, 필요에 따라 상기 감시카메라(101) 또는 감지센서(111) 만을 따로 설치하여 이용할 수 있음은 물론이다.In addition, the surveillance camera 101 may be installed in a plurality of necessary parts in the left and right sides by connecting only a power line as well as the rear of the vehicle, and separately installing only the surveillance camera 101 or the sensor 111 as needed. Of course it can be used.

본 발명은 상기에 기술된 실시 예에 의해 한정되지 않고, 당업자들에 의해 다양한 변형 및 변경을 가져올 수 있으며, 이는 첨부된 청구항에서 정의되는 본 발명의 취지와 범위에 포함된다.The present invention is not limited to the above described embodiments, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

이상에서 살펴본 바와 같이, 본 발명은 차량의 후진시에 전원을 공급하는 후진등의 전원선을 이용하여 후방 감시카메라 및 감지센서의 전원을 공급함과 더불어 필요한 영상과 데이터를 전송 및 수신함으로써 감시카메라 및 감지센서와 운전자 모니터의 연결을 위한 별도의 신호선을 설치해야하는 작업을 행하지 않고도 차량의 후방과 필요에 따라서는 좌우 측방을 영상을 통해 경보할 수 있게 된다.As described above, the present invention provides a surveillance camera by transmitting and receiving necessary images and data as well as supplying power to a rear surveillance camera and a sensing sensor using a power line such as a reverse light that supplies power when the vehicle is reversed. Without the task of installing a separate signal line for the connection between the sensor and the driver monitor, it is possible to alert the rear of the vehicle and, if necessary, the left and right sides through the image.
