摘　　要：随着机载网络的不断进步,飞机飞行管理系统普遍选择1394B总线作为各子系统之间的互联总线。1394B总线由于其复杂的网络协议和庞大的数据量往往会造成各种各样故障的发生,网络中迫切需要一种监控设备能够采集和记录总线数据,从而进行分析和故障定位。文章提出一种1394B监控模块设计与实现,作为数据记录接口模块用来记录、存储1394B网络中的数据内容,并将记录的数据全部或有针对性的发给记录器。同时为满足额外设备的需求,可在不影响当前1394B网络拓扑的前提下将总线上记录的数据同时转发给外挂设备,从而满足飞机不同的任务需求。With the continuous progress of airborne network,1394b bus is generally selected as the interconnection bus between subsystems in aircraft flight management system.Because of its complex network protocol and huge amount of data,1394b bus often causes various kinds of faults.A monitoring device is urgently needed in the network to collect and record the bus data,so as to analyze and locate the fault.This thesis presents a design and implementation of 1394b monitoring module.As a data recording interface module,it is used to record and store the data from 1394b network,and send all the recorded data to the logger.At the same time,in order to meet the needs of additional equipment,the data recorded on the bus can be transmitted to the external devices at the same time without affecting the current 1394b network topology,as to meet the different mission requirements of the aircraft.
