将数据从labview保存到电子表格中，来自NI的介绍(Labview to save data from a spreadsheet, a presentation from NI)

本人为公司UPS产品编写的电脑监控UPS工作的程序(I am prepared for the company' s computer monitor UPS UPS products work procedures)

说明：  产生若干个周期的正弦波数据，以当前系统日期和自己的名字为文件名，分别存储 为文本文件、二进制文件和电子表格文件。(Create text file, data record file and write)

通过labview 对信号进行分析，主要包括基于FFT求信号功率谱(The signal is analyzed by LabVIEW, mainly including the signal power spectrum based on FFT)

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.)

使用研华采集卡，labview驱动，采集数据和存储，曲线显示(Labview data acq excel save and display)

串口数据采集RS232串口是工业中比较常用，也最容易接触到的一种总线协议，台式机上一般都有二个，而现在很多下位机、仪器等很多都还是使用串口通信的。通过RS232串口可以方便的实现Labview与其他测试软件、控制软件的通信。(Serial port data acquisition RS232 serial port is a kind of bus protocol which is commonly used in industry, and it is also the most easy to contact. In general, there are two desktop computers, and many lower computer, instrument and so on are still used in serial communication. The communication between Labview and other test softwares and control software can be conveniently realized through RS232 serial port.)

labwindows CVI打开，操作，新建excel(CVI open, operate, new EXCEL)

labview实现 多条曲线的创建 数据保存在数组里面(labview create multi-curve data stored in the array inside)

基于Labview的直流电机闭环调速 稳定性好(Labview-based closed-loop DC motor speed control)
