摘要
汽车试验设备是汽车性能测试的硬件基础,传统的汽车试验设备由于存在价格昂贵、功能单一、安装不便、功能扩展和升级困难、对温度、工况等要求严格,导致试验成本提高、试验数据不精确等问题.虚拟仪器(Virtual instrument,简称VI)设计思想的提出,恰恰可以很好地解决这些问题,用户可以根据自身需求设计自己的仪器系统,充分利用计算机技术来实现和扩展传统仪器的功能.本文重点介绍了基于虚拟仪器的数据采集系统的软件设计思想和方法.
Automobile performance testing device is the hardware base of automobile performance test. The traditie hal automobile performance testing is proprietary and expen sive, inconvenient to install, and difficult to extend function and upgrade, strict to temperature and work condition. All of them above can result in increased cost, inaccurate test date and so on. Virtual instrument thought can resolute these problems. User can design device system according to its own needs, using computer technology fully to realize and extend traditional device. The article introduces the software design thought and method based on virtual instrument data acquisition system.
