labview-signal

labview 语音信号采集及频谱分析的程序，功能强大好用(labview voice signal acquisition and spectrum analysis)

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.)

labview通过串口与下位机相连，接收数据，可以搜索和拆分数据以获得期望的结果，基本实现处理数据的功能(Receive data through the serial port, you can search and split the data to obtain the desired results.)

说明：  labview 通过OPC 访问西门子PLC(LabVIEW accesses Siemens PLC through OPC)

该程序用于labview信号分析功能，包括小波分析和快速傅里叶变换等(The procedures used for labview signal analysis functions, including wavelet analysis, and fast Fourier transform)

电机转速模拟，包含进度，数据记录，上下限设置，存储文件在桌面test(Motor speed simulation, including progress, data recording, set upper and lower limits, storing files on the desktop test)

登陆界面，能够实现对用户的注册，以及管理员能够对数据进行操作(The login interface enables users to register and administrators to manipulate data.)

基于Labview的电子钢琴设计，通过对声音频率的设置，实现发声及演奏功能(Labview-based electronic piano design, set to the frequency of the sound, vocal and performance features)

说明：  程序实现对信号的小波分析以及频谱分析，具有美观的界面和数据存储功能。(The program realizes wavelet analysis and spectrum analysis of signals, and has beautiful interface and data storage function.)

这是一款基于Labview的变声器，我用的版本是Labview2011，软件的主要目的是改变输入的声音(This is a Labview-based voice changed, I used version is Labview2011, the main purpose of the software is to change the input voice)
