LabVIEW LabSQL工具包，资料完整，vi有额外补充。(LabVIEW LabSQL Toolkit)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)

粮情检测系统，适合粮仓粮食的温度测量的Labview程序。(Grain situation detection system for temperature measurement of grain granary Labview program.)

说明：  关于labview的一些程序，用于了解机器视觉的(Some programs about LabVIEW)

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.

利用labview连接数据库，并用SQL查询访问数据库。对于初学者有很好的帮助作用。(LABVIEW SOL)

用于对于轴承振动信号的共振解调程序，便于对轴承故障信号进行分析(Used for resonant demodulation of bearing vibration signals for easy analysis of bearing fault signals)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

说明：  对单个边缘规则的近圆形图像进行拟合，并在原图像的基础上画近似圆(Fitting a single edge regular near-circular image and drawing an approximate circle on the basis of the original image)

说明：  将直角坐标系数据转换成极坐标数据，以便绘制主轴轴心轨迹(Converting Cartesian coordinates into polar coordinates to plot axis center trajectory)
