坐标系转换

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)

对图像进行腐蚀、膨胀、开运算、闭运算、细化等操作(Corrosion, expansion, opening, closing and thinning of images)

滚动轴承的故障诊断程序，可实现在线诊断和自动识别(Rolling bearing fault diagnosis)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

方根幅值是计算裕度指标与波性指标的必要部分，本文件将其独立做成了一个子VI，方便labview程序调用。希望对小伙伴有所帮助！(The root mean square amplitude is a necessary part of the margin index and the wave index. This document makes it a sub VI, which is convenient for LabVIEW program call. Hope to help small partners!)

说明：  使用.ini文件的用户登陆，跳转，有用户管理功能，可添加，删除帐号，修改密码，修改帐户类型，帐户管理界面点击右键弹出菜单。(Users who use the. INI file log in, jump, and have user management functions. You can add, delete accounts, modify passwords, modify account types, and right-click the account management interface to pop up the menu.)

用于labview excel写入程序（源代码）(Write program for LabVIEW excel (source code))

labview作为上位机，单片机作为下位机，单片机进行温湿度采集，labview进行数据分析和，对继电器进行控制。(LabVIEW as the upper computer, single chip as the lower computer, single chip for temperature and humidity acquisition, LabVIEW for data analysis and data analysis, relay control.)

电机转速模拟，包含进度，数据记录，上下限设置，存储文件在桌面test(Motor speed simulation, including progress, data recording, set upper and lower limits, storing files on the desktop test)

说明：  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.)
