航空数据转发设备仿真器研究与设计

摘要

航空数据转发设备仿真器是用于飞机上的多台仿真设备（如惯导卫星传感器、气象雷达仿真器等）之间的通信。其中AFDX和ARINC429是新一代航空总线协议，硬件方面需要采用标准的ARINC429通讯卡、API-FDX -2通讯卡。数据转发设备仿真器需要完成实验室对硬线的自由转接和数据仿真工作，可按照系统要求进行节点自由转接以及与其它设备进行AFDX、ARINC429数据交互，以满足某航空研究所实验室的仿真需求。%In order to meet the needs of simulation work at the laboratory in an aviation Institute ,the aeronautical data for-warding device emulator that this article describes is used for communication between aircraft simulation equipment ,such as inertial navigation satellite sensors ,weather radar simulator .AFDX and ARINC429 are new and old generation of avia-tion bus protocol ,so we chose standard ARINC429 communication card ,API-FDX-2 communication card to be hardware . Data forwarding device emulator needs to forward the hard-line freely and simulation data ,it can forward freely according to partition node and exchange data with other AFDX ,ARINC429 devices .
