基于混合总线的数据采集记录系统设计

Design of Data Acquisition and Recording System Based on Hybrid Bus

针对当前飞机各系统间多种总线混合,各总线数据信息交互量大,采用传统采集记录难以满足记录需求的问题,设计一种能适应多种混合总线的数据采集记录系统,实现飞行数据的采集和记录。面向当前主流的机载总线1553B、1394b和RS422总线进行数据采集,通过P1010处理器进行总线数据转换与转发处理,以大容量SSD电子盘为记录存储介质,可通过千兆以太网将数据下载到PC或地面回放设备进行直观显示及处理分析,具有很高的工程实用价值。

For the current aircraft various bus mixtures between systems,bus data information interaction is large,the tradition acquisition and recording system is difficult to meet the reguirement of recording,a data acquisition and recording system which can adapt to various hybrid buses is designed,realize the acquisition and recording of flight data.Data acquisition is performed on the current mainstream on the 1553 B,1394 b and RS422 bus,bus data conversion and forwarding processing by P1010 processor,larde capacity SSD electronic disk is used as the recording storage medium,data can be downloaded to PC or ground playback equipment via gigabit ethernet for visual display and analysis,it has high practical value of engineering.
