基于PXI总线的雷抗侦察接收机故障信息自动采集系统设计

摘要

针对越来越突出的装备技术保障问题,以雷抗侦察接收机为例,设计研制了一套基于用于仪器的周边元件扩展接口（PXI）总线的故障信息自动采集系统。该系统广泛采用了模块化、标准化的设计思想,实现了接收机的相关技术指标的实时监测,能够快速准确定位故障源,大大降低了接收机的维修时间,提高了装备保障效率。%Aiming at more and more outstanding equipment technique support problems,taking the radar countermeasure reconnaissance receiver as an example,this paper designs and develops a suit of fault information automatic acquisition system based on peripheral component interconnect extensions for instrumentation(PXI) bus.The system widely adopts the design idea of modularization,standardization,realizes the real time survey of correlative technic indexes of the receiver,which can find the fault resource fast and accurately,reduce the maintenance time of receiver obviously and improve the support efficiency of equipments.
