面向“互联网+”的民机数据链系统发展趋势

Development Trend of“Internet+”Oriented Civil Aviation Datalink System

未来的飞机是空地数据网络中的一个节点。数据链基于多种传输链路,构建网络化的生态系统,为飞机、空管部门、航空公司提供丰富的航迹、气象、放行等数据,提高飞行安全和效率。在总结国外数据链发展规划和路线的基础上,介绍了国内数据链发展规划及路线,针对未来数据链在民机上的应用提出了一种未来民机机载数据链系统架构,分析了数据链地面网络的发展趋势,展望了数据链在下一代空管系统中的应用。

In the future,the aircraft will be a node in the air-to-ground data network.The datalink is a system based on multiple air-ground links to build a networked ecosystem,providing a wealth of track,weather,clearance and other data for aircrafts,air traffic control departments and airlines to improve the safety and efficiency of each flight.On the basis of summarizing the development plan and roadmap of datalink system in foreign countries,this paper introduces the development plan and roadmap of datalink system in China.According to the future implementation of datalink system on civil aircrafts,it puts forward the development trend of airborne datalink system architecture in civil aircraft,analyzes the developing trend of datalink ground network system,and gives prospect of datalink technology implementstion in the next generation of air traffic control system.
