基于边界扫描的航空发动机电子控制器故障注入与检测方法研究
Research on fault injection and detection methods for aero-engine electronic controllers based on boundary scan
摘要
Abstract
The electronic controller of an aero-engine is a complex circuit system designed with numerous large-scale integrated circuits as the core.The traditional contact-based fault injection and detection methods relying on physical probes fail to meet the testability design requirements of such complex circuits.This paper proposes a fault injection and detection method based on boundary scan for the core circuit of the aero-engine electronic controller.Through the analysis of the core circuit,a boundary scan daisy chain and a boundary scan controller are designed,possessing the ability to conduct fault injection and detection based on the interconnection between chips and the boundary scan units inside the chips.The fault injection and detection functions of the two methods are verified,combined with the over-speed protection logic of the engine.关键词
