摘要： The system has a processing unit that collects input data and a peripheral storage device, connected to the processing unit via an interface system, for recording event data in a non-volatile memory, wherein the event data are input data stored for a recording time period relative to a time zero representing a time when a trigger event occurs. The peripheral storage device has also a volatile memory, and the data logging system stores the input data in the volatile memory of the peripheral storage device, when input data are being collected, and, when a trigger event occurs, makes a copy of stored input data as a backup from the volatile memory of the peripheral storage device into the non-volatile memory of the peripheral storage device.
