Digital Recording of Vehicle Crash Data 810810

This paper discusses the development and implementation of a 16 channel data acquisition system for high “G” impact testing which includes a self-contained, on-board data acquisition unit, a programmer-exerciser and debriefing subsystems. The microprocessor controlled, on-board unit contains all signal conditioning, A/D conversion hardware and logic to store 4K 12 bit samples of data per channel. This unit will debrief into an oscilloscope, a desk-top computer or a large disk-based minicomputer system. Advantages over previous systems include the elimination of costly hardware (such as umbilical cables and recorders), and a reduction in pre-test preparation and data processing time.
