计算1——n的平方和大于1000的n的最小值，并计算出累加和(Calculate the sum of squares of 1-N and the minimum value of N greater than 1000, and calculate the sum of accumulations.)

说明：  基于labview的振动信号采集与分析的一段编程(A program of vibration signal acquisition and analysis based on Lab View)

LABVIEW 数据采集，和电机控制，通过板卡可以控制电机的转速，并且能采集电机的转速信号。程序比较简单，不是采用DAQ编写。(LABVIEW data acquisition, and motor control board can be controlled via the motor speed, and can collect the motor speed signal. Procedure is relatively simple, instead of using DAQ write.)

串口读写，基于labview做的，可以实现上位机与下位机调试用(Serial reading and writing, based on labview do, you can achieve the PC and the next crew debugging)

LABVIEW的中文转成Unicode码的模块，可以作为发送短信模块的子VI使用。(LABVIEW of Chinese into Unicode code module, you can send SMS module as a sub VI uses.)

说明：  1. 一个完整数据采集系统的基本组成部分 2. NI 提供了基于哪些平台的数据采集硬件产品，它们分别适用于什么样的应用领域 3. 数据采集设备硬件选型过程中应该关注哪些重要参数(Introduction of NI data acquisition hardware 1. Basic components of a complete data acquisition system 2. NI provides data acquisition hardware products based on which platforms and which application areas they are suitable for respectively. 3. What important parameters should be paid attention to in the process of hardware selection of data acquisition equipment)

用LabVIEW编写，从excel中读取数据到labview中，将labview数据存储到excel中 这个比较简单了，直接利用写入电子表格文件VI。(Write in LabVIEW, read data from Excel to LabVIEW, store LabVIEW data into Excel This is a simple way to write directly to the spreadsheet file VI.)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

说明：  labview宝典书籍的全部代码，希望有助于同学们的学习，所有代码都可以运行(Labview books all the code, I hope to help students learn, all the code can run)

基于LABVIEW虚拟仪器设计的多通道数据采集系统，利用DAQ助手编译，可实现PC机上的数据实时监控及记录(labview daq)
