LABVIEW与PLC的OPC通讯

用Labview编写的一款hart仪表上位机软件，编写hart仪表的上位机通讯软件时可参考。(PC software Labview write a hart instrument, write hart instrument PC communication software reference.)

基于Labview下 可燃气体浓度监测软件 源码 labview 2010(Based on Labview software under the flammable gas concentration monitoring source labview 2010)

Code to calculate the Fast Fourier Transform

任意信号的时频分析仪，包含傅里叶变换和功率谱图等分析。(Any time frequency analyzer based on LabVIEW)

本设计采用NI PCI-6221数据采集卡，运用虚拟仪器及其相关技术于多通道数据采集系统的设计。该系统具有数据同时采集、采集数据实时显示、存储与管理、报警记录等功能，最后使用Web技术实现了采集数据的远程访问(This project use NI PCI-6221 DAQ(data acquisition) card,ingeniously applyes VI technology in the development of a Multi-channel data acquisition develoment and finally achieves a solution which can provide many functions including multi-channel and multi-parameter signal acquisition,huge measurement information storage and management,Alarm record, and Collecting data show that real-time.Finally the use of Web technology to achieve the Acquisition of data remote access.)

说明：  进行减法-卷积-高斯-二值处理，用于边缘查找(Subtraction-Convolution-Gauss-Binary Processing for Edge Finding)

通过labview自动加1计数，给斑马打印机发送ZPL语言 打印标签(Send a ZPL language print label to a Zebra printer by adding 1 counts automatically by LabVIEW)

用LabVIEW编写，从excel中读取数据到labview中，将labview数据存储到excel中 这个比较简单了，直接利用写入电子表格文件VI。(Write in LabVIEW, read data from Excel to LabVIEW, store LabVIEW data into Excel This is a simple way to write directly to the spreadsheet file VI.)

在labview主界面中设置多个功能的选择，调用出子界面(realise multi-task selection and call different sub function in the main front panel of Labiview)

基于Labview的数字滤波器与频谱分析仪 滤波器可以选择是否打开滤波器，可显示波形，可设置滤波器参数，可测量时域、频域的参数，可保存数据、图像；频谱分析仪可显示波形，可测量频域参数(Labview-based digital filter and spectrum analyzer filter can choose whether to open the filter to display the waveform, the filter parameters can be set to measure the time domain, frequency domain parameters, save the data, images spectrum analyzer display waveform, measurable frequency domain parameters)
