Low-Power Data Loop Recorder |
摘要 |
A system and method are disclosed for capturing pre- and post-event data for random events using minimum power. Real-time data is captured and stored in a continuous loop in a segment of a first memory. Upon detection of a designated event, a second memory is powered-on and post-event data is stored to a segment of the second memory. After a designated data capture window, the second memory is powered-off and real-time data is captured in an unused segment of the first memory. The post-event data may be captured in the unused segment of the first memory and later transferred to the second memory. Auto-address logic monitors and controls the storage and retrieval of pre- and post-event in the first and second memory. An energy management system determines and controls which segments of the first and second memory should be powered-on or kept in the stasis mode to store event data.
