峭度指标VI

说明：  【智能四路交通灯控制系统模拟】 这款交通灯模拟系统基于labview软件开发，界面全部自己设计，简洁明了，功能多样化、实用化、具体化，最大程度还原真实的十字路口交通灯控制系统。在以往单纯的红绿交替变化上添加功能如下 1.数码管倒计时功能和灯光闪烁功能，四路人行道灯。 2.配备有操作板可以人为设置各路口交通灯的亮灭时间、闪烁频率，报警器频率，字符串提示。控制暂停和全灭。 3.数码管显示的系统实时年月日及时间。 4.显示以及交通管制中的7种模式（普通模式、三向禁行、南北通行、东西通行、夜间模式、维修模式、紧急模式）和每种模式持续的时间（用计时器来体现）。 现实中可以根据实际路况和需要进行有目地的调整，使交通更加通畅高效。([simulation of intelligent four-way traffic light control system] 1. Digital tube countdown function and light flashing function, four-way sidewalk light. 2. Equipped with operation panel, it can manually set the on / off time, flashing frequency, alarm frequency and string prompt of traffic lights at each intersection. Control suspension and total extinction. 3. The real-time date and time of the digital tube display system. 4. Display and seven modes in traffic control (general mode, three-way traffic prohibition, north-south traffic, east-west traffic, night mode, maintenance mode, emergency mode) and duration of each mode (reflected by timer). In reality, it can be adjusted according to the actual road conditions and needs to make the traffic more smooth and efficient.)

峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)

说明：  利用 labview面向对象编写的快速排序算法，技能学习算法，又能学习基础知识(Use labview object-oriented fast sorting algorithm, skill learning algorithm, and learn basic knowledge)

labview 下的串口编写思路程序，含有多线程，中断，串口参数的保存和例子等。(Labview serial port under the writing way of thinking, the program contains a multi-threaded, interruption, save and example of serial port parameters, etc.)

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.)
