上位机PC与台达VFD-M变频器MODBUS RTU格式

LabVIEW服务器界面，是实现LabVIEW TCP服务器程序的主界面。(The LabVIEW server interface is the main interface to realize the LabVIEW TCP server program.)

利用labview语言进行功率谱分析，并得出分析的结果和图形(use labview to analysis Power spectrum )

说明：  LAbview采集风扇频率实现风扇转速显示，可以手自动控制风扇转速(LAbview collects fan frequency to display fan speed. It can automatically control fan speed by hand.)

主要是labview在串口通讯过程中，采用modbus-crc 16 位校验方法(LabVIEW is mainly used in the serial communication process, using modbus-crc 16 bit calibration method.)

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.)

使用LabVIEW 如何生成应用程序(exe)和安装程序(installer)在 Windows 平台下使用 LabVIEW 如何生成一个独立可执行程序和安装程序(How to build the application using LabVIEW (exe) and installer (installer) on the Windows platform using LabVIEW how to generate a standalone executable and installer)

说明：  实现用户登录，修改密码，权限，用户管理各种功能，基本满足账户管理需要(It can realize various functions of user login, password modification, authority and user management, which basically meets the needs of account management)

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(Labview based digital filter and spectrum analyzer filter, you can choose whether to open the filter, you can display the waveform, you can set filter parameters, you can measure the time domain, frequency domain)

一个完成labview项目，包括NI DAQ数据采集，串口数据采集，数据存储等功能。(A complete LabVIEW project, including NI DAQ data acquisition, serial port data acquisition, data storage and other functions.)

采用LABview编写的信号处理程序，包括各种滤波去噪等功能(Using LABview signal processing procedures, including a variety of filtering de-noising, and other functions)
