Abstract

일반적으로 자동차의 후방감지 시스템은 초음파센서를 이용한 후방 장애물 감지하는 것과 카메라만 이용하여 후방 상황을 영상으로 확인하는 것으로 되어 있다. 또한 이 시스템을 무선으로 전송하는 무선 시스템으로 구현되어 있는 것도 있지만 카메라와 초음파 센서 2가지 정보를 무선으로 동시에 구현한 제품은 있지 않다. 보통의 2.4GHz 주파수를 이용한 무선 시스템은 영상과 음성을 전송할 수 있는 채널로 구분되어 있는데 영상은 기존 채널을 이용하여 전송할 수 있지만 초음파 센서의 신호는 음성 신호를 보내는 채널을 이용하여 전송할 수 없다. 그러므로 초음파 센서의 신호를 무선으로 전송하기 위해서는 별도의 데이터를 전송할 수 있는 무선 시스템을 설치하여야 한다.In general, the rear detection system of a vehicle is to detect rear obstacles using an ultrasonic sensor and to check the rear situation by using only a camera as an image. In addition, there is a wireless system that transmits the system wirelessly, but there is no product that simultaneously implements two types of information simultaneously, a camera and an ultrasonic sensor. The wireless system using the common 2.4GHz frequency is divided into a channel capable of transmitting video and audio. The video can be transmitted using an existing channel, but a signal of an ultrasonic sensor cannot be transmitted using a channel for transmitting an audio signal. Therefore, in order to wirelessly transmit the signal of the ultrasonic sensor, a wireless system that can transmit separate data should be installed.

이 단점을 보완하기 위하여 본 발명은 기존의 무선 A/V 송수신기의 음성전송 부분을 변형하여 기존의 무선A/V 시스템을 이용하는 방식으로 구현하고 있다.In order to compensate for this disadvantage, the present invention is implemented by modifying the voice transmission part of the existing wireless A / V transceiver by using the existing wireless A / V system.

기존 무선A/V 송수신기에서 영상 채널은 그대로 사용하고 음성채널을 이용함에 있어서 우선 변환기 부분이 필요하다.In the existing wireless A / V transceiver, the video channel is used as it is, and in order to use the audio channel, a converter part is needed first.

변환기는 초음파 센서에서 감지되는 데이터를 음성 데이터로 변환하는 역할을 한다. 초음파 센서에서 발생하는 데이터는 음성신호와 구조가 달라서 변환기가 없이는 음성채널을 이용해서 바로 전송을 할 수 없다.The transducer converts the data sensed by the ultrasonic sensor into voice data. The data generated from the ultrasonic sensor is different from the voice signal, so it is impossible to transmit the data directly using the voice channel without the transducer.

변환기를 통하여 음성 신호로 변환된 데이터를 음성 채널을 통하여 수신기로 전송한다. 그리고 초음파 센서로 측정한 거리 데이터를 디지털 신호로 변환한 다음 OSD(한 화면에 다른 화면을 겹쳐서 나타내는 기술) 기술을 적용하여 측정된 거리를 문자로 화면에 나타낸다. The converter converts the data converted into the voice signal to the receiver through the voice channel. The distance data measured by the ultrasonic sensor is converted into a digital signal, and the measured distance is displayed on the screen by using OSD technology.

본 발명은 자동차 후방 감지 시스템에 관한 것으로, 현재 많은 후방 감지 시스템이 사용되고 있으나 사용되고 있는 시스템은 유선방식과 또한 화면 혹은 물체 확인을 구분하여 나타내는 단점을 극복하고 화면과 거리를 화면에 같이 나타냄으로써 운전자의 불편함을 해소하고 유선방식과 달리 자동차에 장착하는 방법도 간편하게 개선하였다.The present invention relates to a vehicle rear sensing system, but many rear sensing systems are currently used, but the system used is to overcome the disadvantages of distinguishing the wired method and identifying the screen or the object and displaying the screen and distance on the screen. To solve the inconvenience, unlike the streamlined method, it is also easier to install in the car.

본 발명의 관련 기술로는 현재 사용하고 있는 유선 방식을 배제하고 무선 방식으로 구현하여 자동차에 설치를 간편하게 할 수 있도록 하였으며 2.4GHz 영상/ 음성 송신기를 이용하여 카메라로 촬영한 영상과 초음파 센서로 측정한 거리를 전송하여 모니터에 나타나게 하였다. 또한, 센서에서 측정한 물체와의 거리정보를 소리로 나타낼 뿐만 아니라 OSD 기술을 이용하여 숫자로 화면에 나타나도록 구현하였다.The related technology of the present invention removes the current wired method and implements the wireless method to facilitate installation in a vehicle. The 2.4 GHz image / audio transmitter measures the image taken by the camera and the ultrasonic sensor. The distance was sent and displayed on the monitor. In addition, the distance information with the object measured by the sensor is not only displayed in sound, but also displayed on the screen by numbers using OSD technology.

본 발명은 사용되고 있는 후방 감지 시스템의 유선방식과 또한 화면 혹은 물체 확인을 따로따로 구분하여 나타내는 단점을 극복하고 화면과 거리를 화면에 같이 나타나게 하여 운전자의 불편함을 해소하고 유선방식과 달리 무선 방식을 사용하여 자동차에 장착하는 방법도 간편하게 개선하였다.The present invention overcomes the disadvantages of separately distinguishing the wired method and the screen or object identification from the rear sensing system being used, and solves the inconvenience of the driver by making the screen and distance appear on the screen, unlike the wired method. It is also easy to install in the car.

The data detected by the ultrasonic sensor is an analog value. As it is output, it converts it into voice signal by using A / D converter which converts it into digital signal and transmits data through voice channel.

그리고 초음파 센서에서 감지된 데이터를 디지털 신호로 변환한 다음 화면에 측정된 거리를 문자로 나타내기 위하여 OSD 기술을 사용하여 해결하였다. And then, the sensor uses the OSD technology to convert the data detected by the ultrasonic sensor into a digital signal and then display the measured distance on the screen as text.

상기한 바와 같이 본 발명은 촬영한 화면을 유선으로 전송하는 방식을 배제하고 무선 방식으로 구현하고 영상과 측정된 거리를 문자로 같은 화면에 나타내고 물체 확인에 대한 소리를 울리도록 하여 운전자의 불편함을 해소하였다.
