Active-Noise-Control

在labview环境下编写实现语音信号的采集播放加噪降噪和滤波功能(Under labview environment prepared to play the voice signals to achieve acquisition plus noise and noise reduction filtering)

本文主要介绍了利用国产普通数据采集卡，基于美国 NI 公司提供的虚拟仪 器软件开发平台 LabVIEW 和实验室原有发动机硬件平台自行开发的一套气缸压 力采集模块和数据分析模块(This thesis primarily introduced software about cylinder pressure and crank angle acquisition and data analysis module. It is designed by using a general data acquisition board, which is based on Virtual Instrument LabVIEW offered by NI and laboratory engine. )

基于串口通信的电机控制界面，VI程序 对电机实现参数监控(Based on serial communication motor control interface, VI program to achieve the parameters of the motor monitoring)

声卡采集示波器，不仅可以调波形，还可以将波形以bmp格式保存，文件读取回放，复位，暂停时调节波形，动态显示测量数据及相应的信号处理数据，具有各种滤波处理。里面附带了流程图和详细的技术文档资料，设计论文。(Design and Realization of Virtual Oscillograph based on LABVIEW )

labview的USRP实验指导书，包含理论，简单的程序框图，不含答案(DWC-USRP- Student Lab Manual)

说明：  示波器的设计，基本上满足日常的使用。可以自动调整频率等功能(Design of Oscilloscope)

清除串口冗余。当下位机偶然有乱码出现时，在新的通讯开始先清除缓冲区冗余信号，然后开始通讯，可以保证通讯更稳健(Clear serial redundancy. Current-bit machines have occasionally garbled when, in the new communications start to clear the buffer zone redundant signal, and then began to communications, to ensure more robust communication)

运用labview开发环境，实现串口通讯，接受串口发送接收的数据(Development environment using labview, serial communications, sending and receiving serial data received )

说明：  1）LabVIEW实现车牌的自动识别，同时提供Gamma变换图像、边缘检测结果、正交投影信息等。 2）文件中附车牌图片、识别结果。 3）2016版本LabVIEW。(1) Automatic recognition of license plate realized via LabVIEW, where gamma transform image, edge detection result, orthogonal projection information are also provided. 2) The license plate pictures and recognition results are attached to the document. 3) LabVIEW 2016.)

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!)
