发明名称 Storage device of car event data recorder
摘要 A storage device of car event data recorders is revealed. The storage device of car event data recorders includes at least two sets of memory or at least one memory set with at least two memory areas. The first memory module (or area) is used to record real time audio/video data with continuous attributes while the second memory module (or area) is for retrieving and recording audio/video data at the time of the accident and/or pre-alarm audio/video data before the accident and/or post-alarm audio/video data after the accident. The interval before or after the accident may be a few decades of seconds. Thereby the storage device of car event data recorders can perform long-term safety control operations and completely record real time audio/video data during, before and after each event. Therefore, certain audio/video data is stored for long-term preservation and checked. Thus the efficiency of the storage device of car event data recorders is improved.
