Abstract
The utility model provides a video monitoring instrument for an automobile. The video monitoring instrument comprises a monitoring system including a front camera, a rear camera, a camera inside the automobile, a display, a main control panel, a storage device and a keyboard input device. Signals of the cameras are connected with the main control panel in wireless mode or through a cable. Video signals collected by the cameras are synthesized through a digital signal processor (DSP) and then stacked with time and other automobile condition information to form image information. According to configuration, one branch of the image information is stored in the storage device, and the other branch of the image information is output to the display to be displayed in real time. The instrument has a common real-time monitoring function and functions of image synthesizing, recording and playback and is convenient for users to use.
Description
Technical field
The utility model relates to a kind of automobile video monitoring instrument, can Real Time Monitoring and preserve the automobile parking state or transport condition inferoanterior, rear and car in motion video.

The utility model content
In order to address the above problem the deficiency that exists with existing product, the utility model provides a kind of instrument, except realizing simple real-time video monitoring, also can be according to current demand, by simple key-press programmable, set duty and the video preservation mode of each camera, prepare against inquiry when needing, evidence obtaining.
The technical scheme that its technical matters that solves the utility model adopts provides a kind of automobile video monitoring instrument, comprises the supervisory system that contains camera, display, master control borad, memory device and keyboard input devices;
Described camera comprises camera in the place ahead camera, rear camera, the car; Described master control borad adopts the ARM+DSP video frequency processing chip; The signal of described camera is connected to described master control borad by the form of wireless or cable, three tunnel vision signals of camera collection are synthesized by DSP in the place ahead camera, rear camera, car, form image information again with after time and the stack of other vehicle condition information.
Described image information is divided into two-way according to configuration: the one tunnel after the H264 compression algorithm becomes the STDVIDEO vision signal of D1 form, be packaged into the playing video file of the mp4 form of standard, be saved in described memory device, another road converts this vision signal to the VGA signal through DA and outputs to described display and show in real time; By described keyboard input devices, the video file of storage can be arrived described display playback through H264 decoding outputting VGA signal; Also the memory device that is loaded with video file can be received and utilize video jukebox software commonly used to play on the computing machine.
Described the place ahead camera is placed on the middle part, upper edge of front windshield, directed forward; Described rear camera is placed into the upper along central authorities of rear seat windscreen, points to the rear; Camera is installed in the front, center position of ceiling in the car in the described car.
Described master control borad comprises CPU, data-carrier store, program storage, image acquisition circuit, image output circuit, memory circuit, real time clock circuit, keyboard interface.
The power supply of described camera is provided by described master control borad.
Described memory device is USB device or SD card.
The power supply of described supervisory system is connected with the power supply storage battery of automobile, is provided with power control switch in the middle of supervisory system and the automobile power source, the break-make of control power supply.
Described supervisory system has GPS interface and driving information interface, and described driving information comprises the speed of a motor vehicle, bearing circle state, gear and throttle information.
The beneficial effects of the utility model are: except possessing general real-time monitoring and control, possess also that image synthesizes, records, the function of playback, be user-friendly to.
