The Development of High-speed Synchronous Temperature Data Acquisition System in Vacuumthermal Test Based on PXIe Bus

摘要: 随着真空热试验的发展，原有的真空热试验数据采集系统在采样速率、采集同步等方面已经不能满足试验需求，不能准确的反应试验件瞬时温度采集需求。基于PXIe高速同步数据采集系统在真空热试验中的运用，对真空热试验高速同步数据采集的需求分析，对系统结构、硬件组成和软件进行了详细说明，并对系统的运行效果进行简单分析。

Abstract: With the development of vacuum-thermal test,the original data acquisition system of the vacuum-thermal test cannot meet the test requirements in terms of sampling rate and acquisition synchronization and cannot accurately reflect the instantaneous temperature collection requirements of test pieces.This paper introduces the development of highspeed synchronous data acquisition system in vacuum-thermal test based on PXIe bus.Analyze the requirements of highspeed synchronous data acquisition in vacuum-thermal test,detailed description of the system structure,hardware and software components.And a simple analysis of the system’s operating results.
