摘要
基于虚拟仪器技术在原有发动机实验测控台架上设计了一种发动机油耗测试系统。系统主要由便携式计算机、NI USB9219多功能数据采集卡、信号调理模块、油耗传感器、油箱、各路油管等组成。油耗传感器输出的信号直接输入到数据采集卡和便携式计算机中,通过图形化语言LabVIEW的编程,用户界面直观地显示在显示器上,并可方便调试,获取实验数据。
A test system of engine fuel consumption is designed based on virtual instrument technology in the original engine test bench. This system consists of a portable computer, NI USB9219--multifunctional data acquisition card, signal con- ditioning modules, fuel sensors, fuel tank, and fuel pipe etc. The output signals of fuel sensors are directly input to NI USB9219 and laptop computers, and the fuel consumption data are intuitively displayed on users＂ interface through the graphical programming tanguage-LabVIEW. It is easy to debug and obtain experimental data.
