用于内燃机数据采集与处理的虚拟仪器技术开发

Development of Virtual Instrument for Data Acquisition and Processing of Engines

基于虚拟仪器技术,以数据采集卡及计算机为主要硬件平台,利用图形化编程语言LabVIEW编程,设计出内燃机数据采集与处理系统。研究结果表明该系统运行可靠,人机界面友好,操作使用方便,且便于用户扩展功能,实现了较高的性价比。该系统的开发成功对于加快内燃机试验进程以及深入开展科学研究具有重要意义。

A data acquisition and processing system for engine based on virtual instruments technology is designed with a data-acquisition board and a PC as main hardware platform and with the graphical language of LabVIEW as programme language. The study results show that this system runs well, has human friendly interface and can be handled easily. This system also facilitates users to extend functions and realizes higher performance-price ratio. The successive development of this system can bring great help to speed up the test process and thorough studying of engine.
