直流电机闭环调速

实时求解振动信号的频率响应，可以用在数据采集过程中实时观察振动信号的频率响应(Frequency response in real time to solve the vibration signal can be used in the data collection process in real-time observation of the frequency response of the vibration signal)

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.)

这是一个基于Labview的usb模拟量数据采集卡的例程源码，可用于二次开发(This is a routine source code of USB analog data acquisition card based on Labview, which can be used for secondary development.)

基于DataSocket节点的远程波形采集，包含服务器端和客户端(DataSocket based remote node waveform acquisition, including server and client)

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：  读取TDMS文件，labview 2016 测试通过。(Read the TDMS file, and LabVIEW 2016 passed the test.)

Labview调用dll文件，实现加、减、乘、除等运算，可以用来学习labview调用dll的方法。(Labview call dll file, add, subtract, multiply, divide, such as computing, the method can be used to learn labview call dll' s.)
