基于labview的信号分析系统，可以实现频谱分析等多种功能(Labview-based signal analysis system)

为了实现对船舶电站的实 时监控，对PLC编写程序，并在LabVIEW作为监控界面的情况，PLC与工控 机之间采用OPC技术实现通讯，GPC与工控机之间采用Modbus串口协议实现 通讯。最后在实现通讯的的基础上，对本系统进行了试验调试，并开发监控界 面。(In order to achieve real-time monitoring of ship power plant, the PLC programming and control interface as in the case of LabVIEW, PLC and IPC communication between the use of OPC technology, GPC and IPC used between the Modbus serial protocol communication. Finally, to achieve communication based on a test of the system to debug, and develop monitoring interface.)

说明：  一个简单的声音采集系统，有声音采集和声音回放功能，还可以将采集到的声音在时域频域进行分析(A simple voice acquisition system has the functions of voice acquisition and playback. It can also analyze the collected voice in time domain and frequency domain.)

说明：  LABVIEW机器视觉通用框架,直接套用于工程项目(LAbview machine vision general framework)

LABVIEW信息处理，可以实时监测振动信号波形的例样程序(LABVIEW information processing, real-time monitoring program examples like the vibration signal waveform)

Labview的小波分解与还原程序，没有调用matlab，配套论文，可以此为基础改成小波去噪程序(Labview wavelet decomposition and reduction program, there is no call matlab, supporting the thesis, this can be changed based on wavelet denoising procedure)

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

说明：  不规则边界单个圆的拟合功能，在原先图片的基础上画近似圆(Fitting function of single circle with irregular boundary)

使用4711采集卡，labview进行信号采集(Use 4711 acquisition card and labview to cquire the Signal)

本程序主要应用labview实现神经网络的功能，本程序是BP功能的实现。(The program is mainly applied labview achieve neural network function, this program is BP function.)
