数据采集编程指南 上篇

labview对excel的调用，同时可以向excel进行写入和 删除数据等操作。(labview call for excel, and can carry out operations such as writing and erasing data to excel.)

说明：  基于.Net的DirectShow LIB包，可以用于Labview调用DirectShow，实现对相机的控制(The. Net-based DirectShow LIB package can be used to call DirectShow by Labview to control the camera.)

基于labview 多路温度测控系统。(Based on LabVIEW multi-channel temperature measurement and control system.)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

应变的采集显示，可实现多通道的显示，包括图形、数据，有相应的操作界面等(strain aquistion)

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)

labview编程使用中，labview和SOL语言之间对数据库的操作。(the use about labview and SQL.)

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.)

安捷伦34401、34410、34411系列远程控制上位机，使用RS232通讯，可以完成万用表的全部功能。(The Agilent 34401, 34410, 34411 series of remote control host computer, use RS232 communication, can be completed with all function table million.)

说明：  LabVIEW经典例程 生产者消费者循环(LabVIEW classic routines producers and consumers cycle)
