机载飞控1553B总线转以太网总线设计

为使某型飞机上1553B总线数据在进行检查核准时,能够快速校准机上当前的飞控参数,需要设计一种1553B总线转以太网总线设备——数字飞控转换器.其可实现对飞控计算机输出的1553B总线数据实时接收解码、总线转换与采集显示.通过FPGA板卡设计,将多路1553B总线数据汇聚,形成一路UDP标准以太网总线输出的网络数据包,PC上位机检查软件通过以太网总线实时接收数据进行记录、监控.通过系统联试证明,所设计的方案合理可行,使用简单,具有一定的实用性.

Design of Airborne Flight Control 1553B Bus Convert to Ethernet Bus

In order to quickly calibrate the current flight control parameters on the aircraft when the 1553B bus data on a certain type of aircraft is checked and approved,it is necessary to,it is necessary to design a 1553B bus to Ethernet bus device that digital flight control converter,which can realize the real-time reception and decoding,bus conversion and acquisiton of the 1553B bus data of the flight control computer output.Through the FPGA board design,the multi-channel 1553B bus data were aggregaed to form a network packets outputted by the UDP standard Ethernet bus.PC inspection software received data in real time through the Ethernet bus for recording and monitoring.The system test and verification show that the design is feasible,simple to use and has certain practicality.
