Abstract

Abstract:

Wedesign and implement a cRIO based remote distributed data acquisition system. It applies cRIO specific 1588 plug-in to the design of time synchronization program, data acquisition, trigger preservation, local preservation and data TCP/IP upload. Data acquisition and test results show that its short-term synchronization precision can reach sub-millisecond level, and millisecond level for long-erm test. It can be applied to optical fiber micro-seismic monitoring system in coal mines.
