CVI 虚拟仪器设计与应用下的事例代码,网上很少有,上传一些供大家参考(labWindows/CVI exmapel lesson four)

一、运行环境： 基于python2.7 二、原理: 图像识别基于tesseract 数据抓包使用httpwatch, IE，识别出所有的POST请求，获取各步骤中数据，分析页面里token等 三、用法: 修改conf_example.py里的买票信息, 然后运行 在不繁重情况下，可以验证提交买票请求，买完后自己去 未完成订单 页面付款 春运的压力环境下，有bug，待完善, python初学乍用，很多地方不 pythonic 四、Todo: 1. 压力下的抢票测试, fixbug 2. 寻找最优server ip 3. httplib 的接口需要封装,包括重连机制 4. 优化不必要的请求 (Author frankiezhu@foxmail.com DATE: 20140108 )

这个项目称为PostMsg ，用于向桌面上的任意窗口发送消息。这在测试COM服务器时很有用，但其本质上可以发送任何类型的消息。- This project is called PostMsg, uses in to the tabletop on free window transmission news. This when tests the COM server is very useful, but it essentially may transmit any type the news.

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．)

说明：  介绍了一种基于仿真软件PROTEUS的单片机步进电机控制系统的仿真应用。整个系 统以AT89C51单片机为控制核心，利用单片机自身的定时中断、I/U输出，并与一些外围器件等有机结合起来，实现采用按键对步进电机的连续调速、实时控制与显示步进电机工作方式等功能。同时，采用C语言进行系统的软件编程，并在PROTEUS环境下通过了仿真验证。(A simulation application of stepping motor control system based on PROTEUS is introduced. Whole Department With AT89C51 as the control core, the system uses the timing interruption and I/U output of the single chip computer itself, and combines with some peripheral devices to realize the functions of continuous speed regulation, real-time control and display of the working mode of the stepper motor by using keys. At the same time, C language is used to program the software of the system, and it has passed the simulation verification under the environment of PROTEUS.)
