Sound-level-measurement

labview程序调用matlab开发环境，采用matlab运行引擎开发(labview program calls matlab development environment, the use of matlab runtime engine development)

说明：  实现带通滤波，在LABVIEW中实现带通滤波。可以运行，大家可以下载看看(Band pass filtering is realized in LabVIEW. It can be run. You can download it)

labview的截图软件 非常好用可以实现桌面截图(LabVIEW screenshot of the software is very good to use the desktop screenshot)

本设计采用NI PCI-6221数据采集卡，运用虚拟仪器及其相关技术于多通道数据采集系统的设计。该系统具有数据同时采集、采集数据实时显示、存储与管理、报警记录等功能，最后使用Web技术实现了采集数据的远程访问(This project use NI PCI-6221 DAQ(data acquisition) card,ingeniously applyes VI technology in the development of a Multi-channel data acquisition develoment and finally achieves a solution which can provide many functions including multi-channel and multi-parameter signal acquisition,huge measurement information storage and management,Alarm record, and Collecting data show that real-time.Finally the use of Web technology to achieve the Acquisition of data remote access.)

说明：  LabVIEW Office 报告生成工具包提供了一个基于交互式配置的 Express VI——MS Office Report,(LabVIEW Office Report Generation Toolkit provides an Express VI-MS Office Report based on interactive configuration.)

LabVIEW 八通道数据采集（生产者消费者结构）可以看一下(LabVIEW eight-channel data acquisition (producer-consumer structure) can look)

Labview与变频器的485通讯实现代码，包含CRC校验子VI。(The 485 communication code between Labview and frequency converter includes CRC checker VI.)

说明：  基于Labview程序的HEX文件解析程序，可以基于此进行程序改进，编写程序下载上位机(Based on the hex file analysis program of LabVIEW program, the program can be improved, and the program can be written to download the upper computer)

说明：  LABVIEW与欧姆龙通信，读写寄存器的数据(Communication between LABVIEW and Omron)

光通信中涉及大气湍流效应，该程序设计了一种大气湍流类型，可进行大气湍流仿真。(Involved in atmospheric turbulence effects in optical communication, the program design of a type of atmospheric turbulence, atmospheric turbulence simulation.)
