本文对LabWindows/CVI软件开发平台下利用多线程技术实现实时数据采集进行了研究。以往采用单一线程进行数据采集,存在数据溢出、数据更新速度较慢的问题。针对以上问题,本文利用LabWindows/CVI软件自带的多线程机制,采用将线程池和异步定时器相互结合的方法来实现实时数据采集线程和数据处理线程,重点讨论了异步定时器的运行机制和多线程的数据保护方法。最后针对上述方法进行了验证实验,实验结果表明该方法提高了数据更新速度,解决了数据溢出的问题,满足了采集实时性的要求。

In this paper, LabWindows / CVI software development platform using multi-threading technology to achieve real-time data acquisition have been studied. Past a single thread of data collection, there is a data overflow and a data updates slow problem. To solve the above problems, In this paper, LabWindows / CVI software comes with multi-threading mechanism, using the thread pool and asynchronous timer combination of methods to achieve realtime data acquisition and data processing thread, This article focuses on the asynchronous timer operation mechanism and multi-threaded data protection methods. Finally, the method has been validated against test, The experimental results show that the method improves the data update rate, solves the problem of data overflow, and meets the requirements of real-time collection.
