本文介绍了如何使MZ—Ⅲ模件式组装仪表和微型机技术相结合,将模拟数字混合技术有效地应用在发动机台架试验系统中,实现对发动机各种工况的快速跟踪以及该工况下试验数据的采集和控制。重点阐述了发动机油门控制和测功机激磁电流控制——两个中小功率快速随动系统的设计思想和系统构成。阐明了在大量引进国外进口设备的潮流下,充分利用国内现有的先进电子仪表枝术和微型机技术进行综合性自控系统设计,以最少投资实现进口设备具有的性能,缩短与国外的技术差距,提高发动机性能试验的效率和自动化水平是具有一定的现实意义。
This article describes how to make the combination of MZ-Ⅲ modular instrumentation and microcomputer technology, the analog digital hybrid technology effectively applied to the engine test system to achieve a rapid tracking of the engine operating conditions and the conditions Under the experimental data collection and control. Focus on the engine throttle control and dynamometer excitation current control - two small and medium power fast follow-up system design ideas and system components. It is clarified that under the trend of introducing a large number of imported equipment abroad, it is necessary to make full use of the existing advanced electronic instrument sticking technology and micro-computer technology to design a comprehensive automatic control system so as to realize the performance of imported equipment with minimum investment and shorten the technical gap with foreign countries It is of practical significance to improve the efficiency and automation of engine performance tests.
