基于Labview求三个数最大值

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：  一个可以通过菜单选择来显示特定内容的小程序(An applet that can display specific content through menu selection)

本项目是以 LabVIEW 为开发平台的环境监控与预警系统，实现了对温度，烟雾和电压电流等信号的实时采集、记录、存储和回放等功能程序的模块化设计，从而达到环境监控的目的。(This project is an environmental monitoring and early warning system based on LabVIEW. It realizes the modular design of functions such as real-time acquisition, recording, storage and playback of signals such as temperature, smoke and voltage and current, thus achieving the purpose of environmental monitoring.)

LabView中UDP通讯，通过IP地址与端口号可以进行单机或局域网内多台计算机之间的信息通讯。(LabView UDP traffic by IP address and port number to the communication of information between multiple computers in stand-alone or LAN.)

labview编程使用中，labview和SOL语言之间对数据库的操作。(the use about labview and SQL.)

说明：  通过labview模拟实现电驱测试，包含功率曲线等(Realization of electric drive test by LabVIEW simulation)

MATLAB编写无穷大电源发生三相短路的程序，已通过编译，有仿真结果(Infinite power happens three phase short circuit)

labview实现的神经网络算法，很有趣。(The neural network algorithm implemented by LabVIEW is very interesting.)

说明：  对excel文件进行读取，并用数组形式和图的形式进行显示。统计数据中的最大值，最小值，平均值，方差。采用中值滤波，滑动平均滤波等方法去除干扰。(The excel file is read and displayed in the form of array and graph. Maximum, Minimum, Average, Variance in Statistical Data. Median filter and sliding average filter are used to remove the interference.)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)
