摘要
虚拟仪器的技术优势在于可由用户自己定义通用仪器系统,且功能灵活,很容易构建,应用面极其广泛。运用LabWindows/CVI开发环境设计了数据播放器。通过UDP通信,手动载入相应的ini文件及数据文件,通过ini文件完成网络通讯、数据变量、数据采样间隔、数据文件格式的配置,采用链表方式管理、维护数据帧的定义部分。可模拟真实采集过程将数据发送出去,可以读取不同类型的数据文件,做到了通用。通过实例验证了设计的实用性。
The technical advantages of the virtual instrument is the General Instrument system defined by the users themselves, it is flexible, and it is easy to build an extremely wide range of applications. Use the LahWindows/CVI development environment to design data player. UDP traffic, manually load the corresponding ini file and data files, through the ini file complete the configuration of network communication, data variables, data sampling interval and data file format, using a linked list mode to manage and maintain the definition part of the data frame, can simulate the real acquisition process the data sent, can read different types of data files, so achieve a common. Through a factual example verify the practicality of the design.
