labview读取USB数据的升级版

利用labview软件对速度进行实时采集显示，对超速状态可以报警(The speed is collected and displayed in real time by using LabVIEW software, and the overspeed state can be alarm)

说明：  摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

Labview制作的倒立摆仿真试验，大家可以参考一下(Labview produced inverted pendulum simulation, we can refer to)

说明：  在LabVIEW编程中，如何采用生产者消费者模式，以有效提高代码编程和维护效率。(n LabVIEW programming, how to use producer-consumer mode to effectively improve the efficiency of code programming and maintenance.)

说明：  通过labview实现停车收费系统，包括串口的选取、读取收费卡号，初始化钱包，进行充值，扣钱，显示余额等功能。(Through LabVIEW, the parking charge system is realized, including the selection of serial port, reading charge card number, initialization of wallet, recharge, deduction, display of balance and other functions.)

一个完整的声音采集程序系统，包含了采集，处理，分析，保存(A complete program of sound collection system, including the collection, processing, analyzing, storing)

声卡采集示波器，不仅可以调波形，还可以将波形以bmp格式保存，文件读取回放，复位，暂停时调节波形，动态显示测量数据及相应的信号处理数据，具有各种滤波处理。里面附带了流程图和详细的技术文档资料，设计论文。(Design and Realization of Virtual Oscillograph based on LABVIEW )

基于labview平台，以弹簧-质量-阻尼系统为基础，做出二阶虚拟仪器实验平台。包括二阶系统的时域，频域响应动态分析。实现单位阶跃信号输入弹簧-质量-阻尼系统后的动画演示。 (Labview based platform to spring- mass- damper system based on virtual instrument to make second order experimental platform. Time domain including second-frequency-domain dynamic response analysis. Per unit step signal input spring- damping system after animation- quality.)

labview程序，可以接收和发送modbus rtu协议信息。“CRC VHL”为循环冗余校验(Labview program)
