数据采集编程指南 上篇

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)

用于labview数据库编程，相关指导资料(Used for LabVIEW database programming, related guidance materials)

可以通过labview进行USB通讯，凄凄切切群群群群群群群群群(USB communication through LabVIEW)

说明：  labview通讯案例，多线程一对多，实现多线程通讯(labview review eefefeffffffff adkadaapadadkada)

labvIEW程序，可以获取本机的硬件信息。(labvIEW program, you can get the machine hardware information.)

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)

以开沟机为背景，程序结合了队列、通知器、状态机等多种结构，实现了参数（两个模拟量、一个脉冲量）的采集、控制的输出（模拟量输出）以及数据的保存。版本已经改为8.6版，大家一同交流学习，共同进步！(In the background trencher, the program combines the queue notifier state machine, a variety of structures, the parametric (two analog, a pulse volume) of the acquisition, the control output (analog output), and data storage . Version has been changed to version 8.6, all of them will share their knowledge and common progress!)

该程序用于labview信号分析功能，包括小波分析和快速傅里叶变换等(The procedures used for labview signal analysis functions, including wavelet analysis, and fast Fourier transform)

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)

自从NI-DAQmx 发布以来，NI 数据采集(DAQ)用户就充分利用了它的许多特性，这些特性是为节省开发 时间和提高数据采集应用程序的性能而设计的。 一个能节省相当大一部分开发时间的特性是NI-DAQmx 应用程序编程接口（API），它在各种设备功能 和设备系列中都是相同的。这就意味着一个多功能设备的所有功能可由同样的函数集编程得到（模拟输 入、模拟输出、数字I/O 和计数器）。而且，一个数字I/O 设备和一个模拟输出设备都可使用相同的函 数集编程得到。在LabVIEW 中，由于多态机制，因而这是可以实现的。一个多态的VI 接受各种数据类 型以用于一个或多个输入和/或输出终端。NI-DAQmx API 在它所支持的所有编程环境中也是保持一致 的。您仅仅需要学会如何使用一个单一的函数集就可以在多种编程环境中对大部分NI 数据硬件进行编 程。 (Since the release of NI-DAQmx, NI data acquisition (DAQ) users take full advantage of its many features, these characteristics are developed in order to save Time and designed to improve the performance of data acquisition applications. A large part of the development time-saving features a NI-DAQmx application programming interface (API), which function in a variety of equipment And equipment series are the same. This means that all the functions of a multifunction device by the same set of functions programming (analog input Into, analog output, digital I/O and counter). Moreover, a digital I/O device, and an analog output device can use the same letter Number set programming to get. LabVIEW, polymorphism, and thus can achieve. A polymorphic VI to accept a variety of data classes Type for one or more input and/or output terminals. NI-DAQmx API it supports all programming environment is consistent s. You just need to learn how to use a single set of functions can)
