摘要
在测控以及故障诊断等诸多场合,需要根据不同的需求对信号采取不同的时频处理方法,现有的系统信号处理方法比较单一,难以满足不同场合的需求。从时频信号处理方法集成的角度出发,介绍了以MATLAB的图形用户界面(GUI)开发环境为基础的信号采集和处理系统的整体设计方案。进而阐述了从信号采集与生成、分析处理以及数据管理3个方面实现该系统的方法。实验结果表明:该信号采集与处理系统使用方便、稳定性好、具有高精确性。该系统提供良好的交互性和扩展性,能够用于实际信号分析与仿真实验。
In manuy cases of test,monitor and fault dignosis,it is in need of using different time frequency processing method to signals according to different demands. The present processing method of system signal is rather simple,which is difficult to meet demands in different conditions. Starting from the time frequency signal acquisition and processing method,the overall design scheme was introduced of the system of signal acquisition and processing based on the development environment of graphical user interface( GUI)program of MATLAB- GUI. Further more,the system realizing method was presented in three aspects of signal acquisition and generation,processing and analysis and data management. The experimental results indicate that the system runs rapidly and stably,as well as the signal data are collected and analyzed promptly and accurately. The system provides a good interactive and extensibility,which can be used in the actual signal analysis and simulation experiments.
