Storage device of car event data recorder
First Claim
1. A storage device of car event data recorders applied to car safety systems with a plurality of audio/video sensors comprising:
- at least a first memory module and a second memory module;
the first memory module is used to record real time audio/video data while the second memory module is for recording audio/video data at the time an event occurred;
the second memory module is connected with the first memory module and a storage mechanism is generated by the connection between the first memory module and the second memory module so that during or after an event, the second module starts the recording automatically, and retrieves and records the audio/video data at the time the accident occurred;
thereby the storage device of car event data recorders performs long-term safety monitoring by the first memory module and completely records audio/video data at the time each event occurs by aid of the second memory module.

Abstract
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.
