飞行模拟器座舱仪表通信技术研究

摘要

针对飞行模拟器座舱仪表控制系统的结构特点,提出基于DSP的以太网控制系统来实现仪表的ARCINC429数据通信；研究了TCP/IP协议栈的移植,并且根据ARINC429协议设计出相应的应用层协议,最后通过FPGA模拟ARCINC429标准的数据.整个系统运行表面,以太网转ARINC429总线控制模块结构简单,稳定可靠.%A new method based on DSP is proposed to realize the ARCINC429 data communication for cockpit instrument in flight simulator. The Ethernet control system is used in the method to meet with the structure characteristics of the cockpit instrument control system. It studied the transplantation of the TCP/IP protocol stack, and the application level protocol comes through the modification of the ARINC429 protocol. Finally, it tested that the standard data frame through FPGA is gotten. The testing results verified that the bus control module of Ethernet-to-ARINC429 is a simple structure and is more stable and reliable.
