摘　　要：研究了虚拟仪器技术在数据采集与分析系统中应用的优势,提出了WGS-84大地经纬度坐标值转换为空间直角坐标系的方法,在此基础上设计一多线程GPS数据采集指向系统,详细探讨了多线程编程中线程之间数据安全传递的方法,由程序运行实验表明多线程编程中采用通知队列技术方式,能够很好的解决多线程之间数据安全传递的问题。This paper introduces the virtual instrument techno/ogy, Analysis of the advantages of its application in data acquisition and analysis system, study the transform methods of WGS - 84 geodetic coordinate to Space rectangular coordinate, design a Multithreaded GPS data acquisition system on this basis. Discussed in detail the method of data transfer between the Multithreaded, the program is run by the experiments show that Multithreaded programming techniques used in the notification queue way, can be a good deal with the problem of data security between Multiplethreads pass.
