针对文本编程语言复杂，开发周期长的特点，结合材料力学应变数据采集实验的需要，存LabVIEW2010平台下设计了数据采集控制软件。调用动态链接库DLL实现下位机与上位机USB通信，利用队列技术、多线程技术调节了数据传递速度、保证数据不丢失，避免由于长时间数据采集造成的程序瘫痪，提高了程序可靠性，遵循模块化的设计思想，方便以后改进和维护，实验表明可以完成对应变信号实时采集、处理显示、存储及数据回放的功能。软件接口简单、开发周期短、性能稳定、易于维护，用于教学实践中，取得较好效果。
針對文本編程語言複雜，開髮週期長的特點，結閤材料力學應變數據採集實驗的需要，存LabVIEW2010平檯下設計瞭數據採集控製軟件。調用動態鏈接庫DLL實現下位機與上位機USB通信，利用隊列技術、多線程技術調節瞭數據傳遞速度、保證數據不丟失，避免由于長時間數據採集造成的程序癱瘓，提高瞭程序可靠性，遵循模塊化的設計思想，方便以後改進和維護，實驗錶明可以完成對應變信號實時採集、處理顯示、存儲及數據迴放的功能。軟件接口簡單、開髮週期短、性能穩定、易于維護，用于教學實踐中，取得較好效果。
