【摘要】 本文介绍一个采用微型计算机控制的发动机稳态性能测试系统.利用该系统可以实现发动机性能试验过程的自动控制,实验数据的自动采集、贮存和处理.该测试系统是在以W780电涡流测功器为基础的发动机稳态性能试验台上,配备了IBMPC/XT微机、DT2805数据采集板等硬件设备,发展出功能齐全的测试软件系统,实现了试验过程的自动化.实验后处理软件,具备了数据的换算、存贮、显示、列表输出,绘图等多种功能.更多还原

【Abstract】 A microcomputer-controlled system to test engine steady performance is described in this pa- per. The automatic control of engine performance test, data acquisition, storing and processing of test data can be done on it. The system hardware was developed on the basis of the eddy current dy- namometer W780, IBM PC/XT microcomputer and DT2805 data acquisition module. The flexible and convenient system software was also developed.更多还原
