说明：  本VI示范了如何通过LabVIEW自身的强大编程能力，开发一套通用的多通道数据采集监测数据库系统。VI包括了主显示界面、用户权限管理、数据采集、超限报警、配置、实时曲线、历史曲线、日志记录、等数据库管理功能。(This VI demonstrates how to develop a common multi-channel data acquisition monitoring database system with LabVIEW's powerful programming capabilities. VI includes the main display interface, user rights management, data collection, overrun alarm, configuration, real-time curve, history curve, log records, and other database management functions.)

labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用(LabVIEW calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI )

用labview编写的基于TCP/IP协议的服务器与客户端通信程序。(Prepared using LabVIEW-based TCP/IP protocol server and client communication program.)

说明：  基于labview的一维小波去噪 该VI是基于matlab的在labview编程的的一维小波去噪(One-dimensional wavelet denoising based on labview)

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 )

峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)

可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)
