labview编写的EMD分解程序 经验模态分解方法（EMD）在非平稳信号的分析和处理中起着重要的作用，为了能够方便的使用EMD方法对信号进行处理，现将LabVIEW虚拟仪器开发平台良好的用户图形界面和MATLAB软件强大的数值分析功能相结合,利用LabVIEW调用MATLAB实现EMD信号处理方法。仿真结果表明对信号进行EMD分解后，使得瞬时频率具有了物理意义，但只是对信号进行了初步处理，可根据实际需要进行相应后续处理。(the labview written EMD decomposition process.Empirical Mode Decomposition (EMD) plays an important role in the non-stationary signal analysis and processing, signal processing in order to be able to facilitate the use of the EMD method, now LabVIEW virtual instrument development platform graphical user interface and the MATLAB softwarepowerful numerical analysis capabilities combined LabVIEW calling MATLAB the EMD signal processing method. Simulation results show that the signal with EMD, making instantaneous frequency has the physical meaning of the initial treatment, but only the signal, the appropriate follow-up treatment can be based on actual needs.)

说明：  通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

使用LabVIEW对输入波形经行傅里叶变换，对比时域信号与频域信号。(LabVIEW for use by the line of the Fourier transform of the input waveform, compared to the time domain signal and frequency domain signals.)

说明：  Snap7是一款开源的32/64位多平台以太网通信套件，用于与西门子S7 PLC进行本地连接。 新款CPU 1200/1500，旧款S7200，小型LOGO 0BA7 / 0BA8和SINAMICS Drives也得到部分支持。(Snap7 is an open source 32 / 64 bit multi platform Ethernet communication suite for local connection with Siemens S7 PLC. The new CPU 1200 / 1500, the old S7200, the small logo 0ba7 / 0ba8 and SINAMICS drives are also partially supported.)
