一种换能器阻抗测试分析及数据管理系统的设计与实现

摘要

A new impedance test and analytical system for transducer is designed and implemented. The test and analysis software running in the host computer is developed based on Labwindows/CVI platform. The host computer communicates with a precision impedance analyzer- Agilent4294A by GFIB. It can not only display the measurement data and graph synchronously with Agilent4294A, but also save data to database. Through the data manage software- users can consult- analysis, or display the lest data saved in the database and draw performance curves for these data. The application results show that the measurement data are accurate, the performance of the system is stable, and the operation is convenient.%设计并实现了一种换能器阻抗测试分析及数据管理系统；基于LabWIndows/CVI开发的换能器阻抗测试软件运行在PC机上,通过GPIB通信接口控制Agilent4294A高精度阻抗分析仪对换能器进行阻抗参数测试,并在PC机上实时显示测试数据和测试曲线,同时将测试结果保存到数据库中;数据管理软件实现了对全部测试数据的查询、分析、显示和报告生成等功能;应用表明该系统测量精度高、性能稳定、操作简便,提高了测试效率,实现了数据与文档的电子化,具有很好的应用和推广价值.
