基于PXI的试车台网络化同步数据采集系统

A Network Synchronous DAQ System for Test Chamber Based on PXI

本文介绍了利用PXI的RTSI触发总线技术,实现了多块板卡之间的严格同步功能,并且结合LabVIEW编程软件对RT-SI进行控制,实现了航空发动机数百个性能参数和监测参数的高精度采集、高速度传输与实时处理分析、图形化显示和警示,以及通过DataSocket实现网络化分享功能。

This thesis introduces the strict synchronization function between multiple boards based on the RTSI trigger technology of PXI bus, and the controlling of RTSI combined with LabVIEW programing software, It aims at the high-precision acquisition, high speed transmission and real time processing analysis, graphic display and attention of hundreds of performance parameters of aero- engine and monitoring parameters, and also the network sharing function through DataSocket.
