【摘要】 本文介绍了利用虚拟仪器技术改制发动机测试系统的情况。以 ＰＣ工控机为主控单元、以ＬａｂＶＩＥＷ为软件开发平台研制的发动机测试系统，不仅大大减少了各种控制按钮、旋钮及功能切换开关，也大大提高了系统的可靠性和抗干扰能力，保证了各参数测试的精度和稳定性．虚拟仪器技术在发动机测试系统的应用，为发动机的研制、生产提供了先进的测试手段，也为虚拟仪器技术在其它领域的运用提供了依据。更多还原

【Abstract】 Description is made of using virtual instrument technique for remake of an engine test system. By virtue of the engine test system developed using an industrial control computer PC as the CPU and a LabVIEW as the software developing platform, not only the numbers of various control buttons and knobs as well as function changeover switches have been largely reduced, but the reliability and the anti-interfernce capability have been improved considerably so that the measuring precision and stability of all parameters could have been ensured. With the application of the virtual instrument technique to an engine test system, an advanced measuring means has been provided for development and production of engines, and the basis has been furnished for virtual instrument technique finding its application in other fields.更多还原
