本VI介绍Labview对数据库前期使用的操作方法，希望和大家一起分享交流！(This VI introduces the operation method of Labview in the early stage of database usage. I hope to share and exchange with you!)

通过labview实现串口数据的实施读取，labview控制继电器动作(The serial port data is read and implemented through LabVIEW, and LabVIEW controls the relay action.)

USB功率计读取，labview2014编写(USB power meter reads, labview2014 write)

labview网页编程指导资料，建议下载(Labview Web Programming Guidelines, Recommended to Download)

网上找了很多Xcontrol的资料，零零散散的，有些是一些基本的介绍，有些只是些图片截图，很多细节的部分没有， 虽然之前照着别人的写了个大概，但是根本不能用， 自己在别人原有的图片的基础上，花了好几天 把问题都解决了， 现在把源码附上，希望能有所帮助。

运用labview8.5软件，创建一个虚拟双通道示波器VI，并实现以下功能： 1、连续采集电压信号，并存储。 2、实现对电压信号的显示处理、实时记录、回放记录，并且将电压信号的算术平均值可存档于excel文档，可读取。(Labview8.5 software used to create a virtual two-channel oscilloscope VI, and to achieve the following functions: 1, continuous voltage signal acquisition and storage. 2, to achieve the display of the voltage signal processing, real-time recording, playback record, and the arithmetic mean of the voltage signal can be archived in the excel document, can be read.)
