On-Bord driving video recorder triggered by manually or automatically triggered the collision record trigger related video signal. Used to monitor, record, store, of running the front of the vehicle and towards the surrounding situation and inside image; in an emergency situation occurs, real-time record of traffic accidents during the image.
Car lane video records instrument, by signal collection processing module, and main processor CPU, and output interface and triggered module constitute, its features is: by said signal collection processing module including intake vehicles ahead image signal of car CCD camera (a,) and intake carriages within image signal of car CCD camera (b); two road video simulation signal OU collection to video pre coding chip (U9) of video signal entered end (14 feet, and 18 feet), in video coding chip (U9) in the conversion why 8 bit digital signal, Through 8 bit parallel data bus (81-90 feet) will this digital signal passed to MPEG-4 hard chip coding chip (U2); by coding chip U2 for video coding output MPEG-4 format of 32 bit data through parallel data bus, and address bus and the control line save to data cache (U3, and U6) in the; in main CPU (U1) judge has accident occurred Shi, through and coding chip (U2) connected of data bus, and address bus will store in cache (U3, and U6) MPEG-4 some time before and after video of the accident data to files saved to the storage card (SDCard).
For traditional video recorder image quality faults of low and poor stability and anti-interference ability is designed based on in-vehicle video recorder TMS320DM642. Improved H.264 video compression algorithms embedded in the DM642, improves the quality of video compression. Using ARM compressed video and easily stored in SD cards, through the identification of abnormal driving information, realization of video information recorded automatically in a dangerous State. Using improved power supply design, improves the stability of in-vehicle environments. Why abnormal traffic anomaly detection, driver veering off to drive traffic accident identification card in order to monitor and provide a reliable factual basis. Experimental results show that the system is stable in a car environment, clear video images that are stored.
The role it plays in our lives more and more important, what are you waiting for, hurry to buy it!
