摘　　要：设计了一种消化道定点施药系统的磁定位数据采集程序,利用Visual C++.Net开发工具开发了基于USB接口的数据采集程序,采用多线程、双缓冲存储技术和面向对象的程序设计方法,实现了施药系统的磁定位数据实时采集和对采集数据的处理与存储等功能,利用内存设备环境和多视图编程方式实现多样化的人机交互界面。实验结果表明:该数据采集程序可以实现多通道数据采集,单通道采样时间小于10μs,能够实时、稳定、正确地获取磁定位数据。A data acquisition program for magnetic marker localization is designed, Visual C ＋ ＋. net is used as programming tools to develop the data acquisition program based on USB interface. The programming methods such as rnuhi-threading, double buffer storage and object-oriented are used to achieve the functions like muhiehannel real-time data acquisition, data processing and data storage. The programming methods of memory device context and multi-view are used to accomplish the man-machine interface. The experiments show that the program can acquire and process the multi-channel localization data in real-time stably and correctly, the single channel sample time is less than 10 μs.
