The present invention relates to a camera in which a power line communication (PLC) circuit is incorporated in a rear camera of a general vehicle. More specifically, an image and a control signal of the camera are connected using a power line. The present invention relates to a camera for monitoring a vehicle with a built-in PLC function that facilitates installation by incorporating a power line communication circuit into a camera so as to be transmitted to a monitor.

In general, the rear surveillance camera system for the vehicle is installed at the rear of the vehicle to shoot the rear of the vehicle with a camera, and the captured signal is reproduced through a monitor located in the driver's seat so that the user can reverse and park while watching the monitor, The rearview mirror or rearview mirror allows the driver to back up conveniently without having to monitor the rear.

As such, the related art of a rear surveillance camera system that conveniently monitors the rear of a vehicle is a rear camera, a power line communication transmitter (hereinafter referred to as 'PLC TX'), a power line communication receiver, It is referred to as 'PLC RX'), and it is configured as a monitor to connect the rear-view camera image of the vehicle to the PLC TX, and the PLC TX is connected to the reverse light of the vehicle and transmitted using the vehicle body and the vehicle's own power line. PLC TX and PLC RX are separately connected between the rear camera and the monitor because the image is received from the PLC RX mounted at the front of the monitor and connected to the monitor Video In terminal so that the monitor is automatically displayed when the vehicle is reversed. There was a problem with the burden of cost and installation hassles to be installed.

In order to solve the above problems, the present invention has a purpose to reduce the cost and simplify the installation by embedding the PLC TX and PLC RX, which is an image transmission device using the power line and the body of the vehicle to the camera and the monitor.

In order to achieve the above object, the present invention is a camera for monitoring the rear of the vehicle consisting of a camera for photographing the rear image of the vehicle and a monitor for displaying the image taken by the camera,

By connecting a power line communication circuit for outputting the image signal of the camera to the monitor through a power line and being connected to the output terminal of the camera and the input terminal of the monitor, the image data is transmitted to the power line without a separate power line communication circuit. It is a camera system for rear view monitoring of vehicle with built-in PRC function.

Hereinafter, with reference to the accompanying drawings in order to explain the present invention in detail.

1 is a view showing the overall configuration of a camera system for monitoring a vehicle with a built-in PLC function according to the present invention.

As shown in FIG. 1, the camera unit 100 installed to capture an image of the rear of the vehicle includes a camera 110 for capturing an image, a power cable 111 for supplying power to the camera, and the camera. The video cable 112 for transmitting an image signal captured by the camera, and the PLC TX 120 for transmitting an image from the video cable 112 are integrally built in the camera unit, and the PLC TX 120 is a vehicle. When connected to the reverse light 130 of the vehicle when the reverse power is applied to the reverse light when the power is supplied to the camera 110 via the PLC TX 120, the camera 110 is photographed One image signal is transmitted to the power line 200 by transmitting the image signal to the reverse lamp 130 through the PLC TX (120).

Here, the power line 200 preferably uses both the vehicle self power line 210 connected to the reverse light 130 and the vehicle body 220 connected to the PLC TX 120.

An image signal of the camera unit transmitted through the power line 200 is displayed on the monitor unit 300. In the monitor unit 300, the PLC RX 320 and the monitor 330 are integrally built in the vehicle. Receives power and image signals from the cigar jack 310 connected to the power line 200 in the power source 200 to remove the power from the PLC RX 320 for the power and video signals transmitted from the image It extracts only the signal and transmits it to the monitor 330 to display the image taken by the camera unit 100 is a system for monitoring the rear vehicle with a PLC function.

In this case, the power cable 111 and the video cable 112 of the camera 110 are applied to the PLC TX 120 circuit and integrated into one cable to connect to the backward light 130 of the vehicle. Built-in rearview camera system.

In addition, the monitor 330 has a built-in PLC RX 320 to remove power from the PLC RX 320 with respect to the power and video signals transmitted from the power line 200, and extracts only the video signal to the monitor 330. It is a camera system for monitoring the rear of the vehicle with a PLC function, characterized in that to display an image on.

As described above, although the preferred embodiment according to the present invention has been described, the present invention is not limited to the above-described embodiment, and the present invention belongs to the present invention without departing from the gist of the present invention as claimed in the following Utility Model Claims. Anyone with ordinary knowledge will have the technical spirit of the present invention to the extent that various modifications can be made.

As described in detail above, the camera system for monitoring a vehicle having a built-in PLC function according to the present invention has a PLC circuit embedded in a rear camera and a monitor of the vehicle, respectively, so that it is easy to install in a vehicle and reduces costs.
