包络检波

很实用的窜口数据采集系统 版本：labview8.5(Very practical channeling port data acquisition system version: labview8.5)

说明：  基于计数器和labview高精度软件计时vi实现两个脉冲信号间的高精度时间测量(High precision time measurement between two pulse signals based on counter and LabVIEW high precision software timing VI)

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.)

基于labview的风电轴承故障检测与监测(Wind power bearing fault detection and monitoring based on labview)

测试电源的三相电压，包括幅值、频率、相位等信息。(3 pulse voltage test)

调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)

说明：  上位机使用LABVIEW显示心跳曲线， USB采集，单片机采用STM32F103C8，心跳检测芯片采用AD8232，利用单片机自身AD转换(The upper computer uses LabVIEW to display the heartbeat curve, USB to collect, SCM uses stm32f103c8, heartbeat detection chip uses ad8232, SCM uses its own ad conversion)

for循环判断最大值，最小值。熟悉FOR循环的用法(For loop judges maximum and minimum. Familiar with the use of FOR loops)

几乎所有的自动设施一一从工业机器到医疗设备一一其组件如何移动都必须按照控制方式执行。移动负载最常见的方法就是使用一些电机元件如电动机。我们来学习如何控制基于电动机的系统，并探究NI公司所提供的各种不同的机器控制解决方案。(Almost all auto facilities one by one how to move from industrial machinery to medical equipment eleven components must be performed according to the control mode . Moving load is the most common method is to use some of the motor components such as motors. Let s learn how to control the motor- based systems)

LabVIEW编写的多通道数据采集。利用的NI的DAQmx编写。(LabVIEW prepared by the multi-channel data acquisition. Use the NI DAQmx write.)
