Way of Real-time Acquisition 1553B Data in Flight Test

摘要:

针对飞行试验中1553B总线的实时采集,提出了一种新型的实时采集方法,充分利用DSP的灵活性和FPGA的快速并行性,构建了一种快速定位的1553B总线数据信息的查表机制,实现将1553B总线特定的数据字从总线数据中实时挑选出来,用于飞行试验的遥测监控;详细论述了飞行试验1553B总线采集的方法与特点,阐述了1553B总线数据快速过滤的方法与实现;该方法经过实验和飞行试验验证,不仅可以实现对机载1553B总线的数据采集功能,还可以将需要的1553B总线数据字从总线上实时筛选出来,满足飞行试验的遥测监控需要。

Abstract:

Aiming at real-time acquisition of 1553B bus in flight test,the new technique of real-time acquisition is proposed,fully utilizes DSP flexibility and FPGA parallelity,the way of finding the words of 1553B bus data message by look-up table is proposed,in order to data monitoring in filght test.The detailed description is discussed in the acquisition way of 1553B bus,and realization. The way and realization of the rapid filtration about 1553B details is also discussed. It is proved that finishing the fuction of acquisition 1553B data,also the 1553B words filtering of 1553B bus data message to meet the demand of flight test.
