摘要
阐述了车辆行驶中的音视频等参数记录的研究与应用。系统采用MP4压缩方式获得音视频数据,结合行车中的险情信号来减少实际记录的数据量,通过SD卡存储实现了全数字化的数据采集与记录,使得系统的可靠性大大提高。多种可选工作模式能给驾乘者更大的选择自由,多媒体播放功能充分发挥了装置的附加功能。
The article expatiates on research and application of audio/video and driving data recording in vehicle driving. The system encodes the data with MP4 format and reduces the data saving with dangerous signal detecting. With the data saved in SD card, this design can realize fully digital recording and obtain highly reliability in working. The article discusses the different working mode can be selected by drivers. With multimedia playback ability, we fully used digital chips and processor add -in functions. This recorder research, designed in combination with data recording and multimedia playing in vehicle has most valuable application in the future.
