LABVIEW与PLC的OPC通讯

labview编写的PID控制程序很实用，可以参考对于用labview编写控制程序的人来说很好(the labview written PID control procedures is very practical reference for the people who write the control program using labview)

通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

利用LabVIEW编写希尔伯特黄变换HHT的算法，实测可用，包括总程序 ，以及IMF，样条插值等各个子VI 函数(Use LabVIEW to write Hilbert Huang Transform HHT algorithm found available, including the overall program, as well as IMF, each sub-spline interpolation function VI)

温度采集，多通道温度采集，实现温度采集。(temperature come on here there is a good solution to fetch temperature.)

用于labview数据库编程，相关指导资料(Used for LabVIEW database programming, related guidance materials)

用LABVIEW实现保存数据的功能，使数据不会没有了(LABVIEW save data, so that data would not be without)

SMTP E-mail Library to send mail over Exchange Server

labview TDMS的各种高速存储功能，(LabVIEW TDMS a variety of high-speed storage function,)

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.)

说明：  使用labview采集16通道数据，采集10次，保存成tdms格式，并对所有数据进行频谱分析，有效值和峭度等指标的10次趋势分析，可在趋势图中点击光标查看原始波形(Using LabVIEW to collect 16-channel data, collect 10 times, save them in TDMS format, and analyze 10 times trend of all data, such as spectrum analysis, RMS and kurtosis. Click on cursor in trend map to see the original waveform.)
