【摘要】 在介绍单行程快速压缩机原理的基础上,开发了其数据采集与处理系统,并讨论了该系统的结构组成和工作原理。本数据处理系统采用凌华公司的PCI-9812(4通道同步采集)采集卡与研华公司的PCL-818(多功能)数据采集卡来实现瞬时工作参数的高速采集和处理。根据试验获得的活塞位移曲线、气缸压力曲线及压力-位移曲线,证明本系统采集到的数据具有良好的可靠性。更多还原

【Abstract】 A brief description of a single-stroke rapid compression machine was given and its data acquisition and processing system was developed.The structure and the working principle of the system were presented.A 4-channal synchronous collecting card PCI-9812 of Adlink Technology Inc.and a multi-functional collecting card PCL-818 of Advantech Co.were used in the system to perform the high-speed acquisition and processing of the transient parameters.Recorded piston displacement versus in-cylinder pressure traces and other parameters by the developed system proved its accuracy and rebiability.更多还原
