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：  使用.ini文件的用户登陆，跳转，有用户管理功能，可添加，删除帐号，修改密码，修改帐户类型，帐户管理界面点击右键弹出菜单。(Users who use the. INI file log in, jump, and have user management functions. You can add, delete accounts, modify passwords, modify account types, and right-click the account management interface to pop up the menu.)

说明：  labview 振动分析软件,该软件可通过声卡采集信号(LabVIEW vibration analysis software that can be collected through the sound signal)

《Labview高级编程与虚拟仪器工程应用》第10章，关于液压系统测试的源码。包括： 1.“溢流阀动态”测试程序，其中小波变换使用了光盘中提供的VI,来自NI公司的高级信号处理工具包6.1版。“溢流阀动态.vi”是主程序。 2.“液压教学实验台”，“液压测试系统.vi”是主程序。 3.“机油泵”试验程序需要较多外部硬件支持。其中的dll用于国内某一特定品牌扭矩仪。“程序”文件夹的“main.vi”是主程序。 4.“转向泵”试验程序需要外部硬件支持。“程序”文件夹的“转向泵试验.vi”是主程序。(Labview high-level programming and virtual instrument engineering application)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)

说明：  LabView信号处理算法，包括功率谱，幅值谱，小波分析等(LabVIEW signal processing algorithm)

基于LABVIEW的两辆模拟车在运行，当后车有超越前车的可能时，自动减速，有用到LABVIEW的多处知识(LABVIEW-based simulations of two cars running after the car when overtaking vehicles when possible, automatic deceleration and useful knowledge to many of LABVIEW)

说明：  本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)
