摘要
介绍了民航超高频(VHF)飞机通信寻址与报告系统(ACARS)机载通信系统及通过该系统实现地空数据链通信管理采用的ACARSIP应用消息处理机制,采用了基于DSP+FPGA的ACARS通信系统消息处理方案,描述了上行消息处理、下行消息处理、CSMA机制、信道质量检测、子网统计数据和审计模式等六个方面进行的设计与实现。最后对ACARS通信系统消息处理进行了总结分析,并指出了该实现方案可推广应用的方向。目前该方案已应用于国内民航ACARS数传通信系统中,并实现了与国际民航电台的互通,正确接收率达到100%,通信稳定可靠。
This papaer introduces the civil aviation Very High Frequency（VHF） Aircraft Communication Addressing and Reporting System （ ACARS ） communication system and the air-ground communication management using the ACARSIP handling mechanism based on the civil aviation VHF ACARS communica-tion system. The ACARS communication messages handling mechanism based on DSP and FPGA is used in the civil aviation VHF ACARS communication system, and the design and implementation of up-link signal processing, down-link signal processing, Carry Sense Multiple Access（ CSMA） mechanism, chan-nel quality detecting, subnet data statistics and audit pattern is described. Finally, the ACARS communi-cation messages handling mechanism is analyzed and summarized, and its application future is pointed out. This scheme has been applied in china’s first civil aviation ACARS data-communication system, and a sta-ble communication quality of 100% correct rate of receiving is achived as communicating with the interna-tional civil aviation radio.
