基于LabVIEW的电磁波数据采集实验系统开发与应用

Experimental Teaching Application of Automatic Electromagnetic Data Acquisition System Based on LabVIEW

应用主控计算机、网络分析仪、三维直角坐标仪和天线构建了全自动电磁波数据采集系统。通过图形化编程语言LabVIEW设计的实验系统可在实验室内实现电磁波数据自动采集,并实时显示当前波形,克服了传统实验中每一测量点需手动保存数据的枯燥耗时。通过对比目标体的数值模拟结果和实际测量所得的物理模拟结果,可直观地了解不同介质对电磁波的响应情况,充分调动学生学习的积极性,加强学生的专业技能训练,提高学生的科学素养。

Depending on the computer, network analyzer, three dimensional coordinate instrument and antenna, the authors developed an automatic electromagnetic data acquisition system in the laboratory. The system was designed by using graphical programming language called LabVIEW. It could do data acquisition and real-time display, and overcame the tedious and time-consuming work that data were manually saved at each measurement point in the traditional experiment. This automatic electromagnetic data acquisition system plays a very important role in strengthening professional skills and training the creative ability of students. It can improve the training quality of students.
