Design and Implementation of In-situ Detection for Airborne Electronic System of a Helicopter

摘要:

针对某型直升机机载电子系统性能先进、种类繁多而外场保障又缺乏快速、有效检测手段的情况,研究设计了一种小型组合式多功能原位检测设备,该设备主要由便携维护诊断检测仪器(PIP)及便携维护辅助设备(PMA)两大部分组成。其中PIP用于提供原位检测所需的激励、测量资源是原位检测设备的主要部件；PMA通过网络接口对PIP进行控制,是PIP的主要人机交互载体,通过在PMA上运行相应测试程序完成机载电子系统的故障检测。针对不同机载电子系统的原位检测只需在PIP主机中更换相应资源模块及在PMA中运行对应测试程序即可。所设计原位检测设备为某型直升机外场保障提供有效的排故检测手段,可提高外场维护效率、降低全机电子系统保障费用、能满足野战环境下快速保障的要求。

Abstract:

Aiming at the advanced performance and variety of a helicopter"s airborne electronic system and the lack of fast and effective detection means for field support, a small combined multi-function in-situ inspection equipment is designed. The equipment is mainly composed of PIP and PMA. The PIP is used to provide the excitation and measurement resources needed for in-situ detection. It is the main component of the in-situ detection device. The PMA controls the PIP through the network interface. It is the main human-computer interaction carrier of the PIP. By running the corresponding test program on the PMA. Complete fault detection of the onboard electronic system. For in-situ detection of different onboard electronic systems, it is only necessary to replace the corresponding resource module in the PIP host and run the corresponding test program in the PMA. The designed in-situ inspection equipment provides an effective detection method for the outfield protection of a helicopter, which can improve the maintenance efficiency of the field, reduce the maintenance cost of the whole electromechanical subsystem, and meet the requirements of rapid protection in the field environment.
