摘要
1.引言 压气机实验提出了更高的要求,测试系统不仅只具有数据采集的功能,而且是一个集控制、数据采集、实时处理、打印、绘图等于一体的多功能自动化测试系统。以此为目的,建立了一个以IBM PC/XT微型计算机为中心控制机的适于全台压气机实验的多功能大型数据采集处理自动化系统。
An automation test system that is controlled by the microprocessor and used in the multi-stage compressor experiment is described. Based on the analysis of the compressor experiment performances, a complete hardware system structure is set up. It is composed of a IBM PC/XT computer, a large scale sampled data system, the moving ma chine with three directions, the scanners, the digital instrumentations and some output devices. A program structure of real-time software system is described. The testing results show that this test system can take the measure of many parameter magnitudes in the blade row places and on a boundary layer on different states. The automatical extent and the accuracy of experiment is increased and the experimental cost is reduced.
