振动信号数据采集

labview的文字滚屏显示，效果类似LED屏幕的滚屏显示。(Scrolling Display)

3σ准则 利用LabVIEW编写 剔除粗大误差(to Elimitate the gross error)

本程序是用LabVIEW编写的，具体是把16进制转2进制字符串(This procedure is written in LabVIEW, specific is to switch the hexadecimal 2 hexadecimal string)

说明：  NI USB-6001电压/阻测试项目源代码（labview2017） 1，使用io触发，自动扫描io上升沿，输入io可选。 2，使用差分方式采样，双通道同时采样，采样数据实时显示。 3，可手动触发采样，采样率，采样数，测试周期可自定义。 4，可保存控件值，运行程序自动加载上次保存的控件值。 5，数据保存到.xls表格，每天新建以年-月-天命名的文件，每个月创建一个文件夹存放数据。 6，测试结果通过USB-6001自带io输出。 真实项目应用源代码!(1. Use IO trigger to scan the rising edge of IO automatically. Input IO is optional. 2. Sampling by differential mode, sampling by two channels at the same time, and real-time display of sampled data. 3. Sampling can be triggered manually. Sampling rate, sampling number and testing period can be defined. 4. The control value can be saved, and the last saved control value can be automatically loaded by the running program. 5. Data is saved to the. xls table. New files named year-month-day are created every day, and a folder is created every month to store data. 6. The test results are output by USB-6001 with io.

本项目是以 LabVIEW 为开发平台的环境监控与预警系统，实现了对温度，烟雾和电压电流等信号的实时采集、记录、存储和回放等功能程序的模块化设计，从而达到环境监控的目的。(This project is an environmental monitoring and early warning system based on LabVIEW. It realizes the modular design of functions such as real-time acquisition, recording, storage and playback of signals such as temperature, smoke and voltage and current, thus achieving the purpose of environmental monitoring.)

Labview的详细开发指南，包括：双精度数据不适于相等比较（内置函数）；顺序结构是“结构”吗？；到底什么是“节点”；XY GRAPH的输入参数形式 ；整型数据类型和内存映射；状态机的基本概念 ；状态机的基本类型顺序结构 ；状态机的基本类型之标准状态机 ；事件结构中的TIMEOUT进行数据采集合适吗 ；全局变量、移位寄存器和功能型全局变量的性能比较等。(Labview detailed development guidelines, including: double precision data is not suitable for equality comparison (built-in function) sequential structure is " structural" it? In the end what is " node" input parameters of the form XY GRAPH integer data types and memory mapping basic concept of the state machine basic types of sequential structure of the state machine basic types of state machine standard state machine event structure The TIMEOUT data collection suitable for you global variables, shift registers and functional performance comparison of global variables and so on.)

上位机服务器程序，可以动态监听连接上来的设备，与客户端通讯，发数据。(The upper computer server program can dynamically monitor the connected devices, communicate with the client and send data)

说明：  数据采集​ ​ 的声音采集可以用于普通麦克风，麦克风等，利用LABVIEW写(DAQ sound collection can be used for ordinary microphone, microphone, etc., written using LABVIEW)

说明：  调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)
