labview

LabVIEW心电检测系统，主要是滤波 信号采集 频谱分析 显示波形等(LabVIEW ECG detection system is mainly filtered signal acquisition spectrum analysis shows waveforms)

说明：  可以将acces数据库中文件导入到excel表格中(updata the data from access to excel)

labview菜单使用方法，包括菜单的创建，事件结构的编写(labview menu use, including the creation of menus, event structures prepared)

解决plc 与 labview 写的上位机通讯的 示范例子。

倍频程带通滤波器,实现倍频程分析和计算信号的有效值(Octave bandpass filter to achieve octave analysis and calculate the effective value of the signal)

说明：  NI USB-6001电压/阻测试项目源代码（labview2017） 1，使用io触发，自动扫描io上升沿，输入io可选。 2，使用差分方式采样，双通道同时采样，采样数据实时显示。 3，可手动触发采样，采样率，采样数，测试周期可自定义。 4，可保存控件值，运行程序自动加载上次保存的控件值。 5，数据保存到.xls表格，每天新建以年-月-天命名的文件，每个月创建一个文件夹存放数据。 6，测试结果通过USB-6001自带io输出。 真实项目应用源代码!(1. Use IO trigger to scan the rising edge of IO automatically. Input IO is optional. 2. Sampling by differential mode, sampling by two channels at the same time, and real-time display of sampled data. 3. Sampling can be triggered manually. Sampling rate, sampling number and testing period can be defined. 4. The control value can be saved, and the last saved control value can be automatically loaded by the running program. 5. Data is saved to the. xls table. New files named year-month-day are created every day, and a folder is created every month to store data. 6. The test results are output by USB-6001 with io. Real Project Application Source Code!)

labview的文字滚屏显示，效果类似LED屏幕的滚屏显示。(Scrolling Display)

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 )
