Abstract

A system for monitoring, recording, and analyzing operational and incident data from a machine, particularly a vehicle. The system includes a computer controlled device, mounted onboard the machine, which collects and records data supplied to it from a variety of sensors positioned to sense operational parameters of the machine. The device provides for storing operational data at one frequency while storing data surrounding an incident or triggering event at a higher frequency, thus, recording incident data with a higher resolution than that associated with normal operating data. The incident data is stored at a higher frequency for predetermined periods both before and after the incident or triggering event.
