正弦信号收发

说明：  labview 的循环创建数组，并存入电脑excel(The LabVIEW loop creates an array and stores it in the computer Excel)

自相关算法的labview实现，需要设计相关参数。(Labview autocorrelation algorithm to achieve)

说明：  labview采用DAQ采集数据进行采集。(LabVIEW uses DAQ to collect data.)

CRC16的9个LabVIEW算法CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB，开发环境LabVIEW2013(9 LabVIEW algorithm of CRC16: CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB The development environment version is LabVIEW 2013)

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!)

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

说明：  上位机使用LABVIEW显示心跳曲线， USB采集，单片机采用STM32F103C8，心跳检测芯片采用AD8232，利用单片机自身AD转换(The upper computer uses LabVIEW to display the heartbeat curve, USB to collect, SCM uses stm32f103c8, heartbeat detection chip uses ad8232, SCM uses its own ad conversion)

说明：  labview读取 cad dxf文档,包括圆直线线段等等(read CAD dxf include circle line)

对LabVIEW进行二次开发，对信号进行聚合经验模态分解(To LabVIEW second development, the signal to carry out the polymerization of empirical mode decomposition)

labview写的modus CRC 校验Vi。 输入发送内容自动计算出CRC校验码。
