【摘要】 ARINC 656规范描述了数据链通信系统和飞行管理系统之间的数据交互规范。分析了ARINC 656规范的协议结构，提出了一种基于ARINC 656改进的FANS 1/A+与FMS通信机制设计方案，通过C++和Socket等编程技术实现了FANS 1/A+和FMS数据交互的基本功能并完成了交互验证，FANS 1/A+和FMS之间通信机制的优化为飞机提供更加及时有效的空-地通信能力，使得飞机更加智能，可有效提高通信质量和运营效率。更多还原

【Abstract】 The ARINC 656 specification describes the data exchange specification between the data link communication system and the flight management system.This paper analyzes the protocol structure of ARINC 656 specification,and proposes an improved FANS 1/A+ and FMS communication mechanism design scheme based on ARINC 656.The basic functions of data interaction between FANS 1/A + and FMS are realized through programming techniques such as C ++ and Socket and verified.The optimization of the communication mechanism between FANS 1/A + and FMS provides the aircraft with more timely and effective air-to-ground communication capabilities,making the aircraft more intelligent,and effectively improving communication quality and operational efficiency.更多还原
