Design and Implementation of In-situ Testing System for Airborne Electronic Systems Based on ATML
During performing tasks,helicopter airborne electronic systems have problems such as difficulty of fault detection and isolation,low efficiency of on-site maintenance and support,and lacking of effective fault-detection tools,an in-situ testing system for airborne electronic system is designed based on automated test Markup language(ATML).It describes the basic composition,work-ing principle,hardware structure,software architecture and cable switching design method of the in-situ testing system.Taking an airborne power distribution system as a case study to design the in-situ testing requirements analysis and test plan.After that,the ATML standard is used to develop the development method of test programs based on the testing software platform SGTS.Further-more,this method is applied to the in-situ testing system development for a certain type of helicopter.After practical verification,the in-situ testing system has significantly improved the fault detection and isolation indicators of airborne electronic systems,and provi-ding an effective and convenient means for helicopter field troubleshooting,on which improves the efficiency of field-maintenance.
