基于虚拟仪器平台的凸轮检测数据处理系统的设计摘 要以往的对数据处理分析中，都会存在灵活性不强而且成本较高等缺点。本次论文讨论的课题是结合工厂生产要求，设计基于虚拟仪器对检测数据处理的系统。不但提高了灵活性而且降低成本更具有实时性等优点。工厂机械生产中，通常会对机械进行凸轮检测，这时会产生大量的数据，而且会对同一型号或同一参数进行多次检测。这便造成时间的浪费，同样，久用的机械设备也要进行检测，假如没有参数作为参考，可能耽误生产。本设计主要以两个工作任务来解决这些问题，一是通过对凸轮检测出来的数据进行处理，讨论一种在 Lab Windows／CVI 平台能对 Microsoft Access 存储的数据进行调用，对历史数据的存放和读取以及新数据的写入。二是利用 Lab Windows/CVI 与武汉亚为科技的 USB Adio 模块实现数据传输，通过另一台检测装置对数据的处理。实践表明该方案对于数据管理切实可行。关键字：虚拟仪器；设备驱动、数据库 USB AdioAbstractPrevious analysis of data processing, the high cost will still exist and flexibility in faults. This paper research topic is combined with factory production requirements, the design of detection data processing based on virtual instrument system. Not only can improve the flexibility and reduce the cost more has the advantages of real-time performance.Factory machinery production, usually to CAM mechanical testing, then will produce large amounts of data, and many times for the same model or parameter detection. It will cause waste of time, again, a long time with the machinery and equipment also want to test, if there are no parameters for reference, may hold up production. This design mainly by the two task to solve these problems, one is to process the data detected by CAM, research in Lab Windows/CVI platform can call on Microsoft Access the data stored on the storage of historical data and read and write new data. 2 it is using Lab Windows/CVI and RS232 serial interface for data transmissi...
