实现飞机状态监视的ACARS数据链新应用

法航447空难和马航370失联事件促使航空公司更关注对飞机的监控。分析了常用的飞机通信和监视手段，提出了一种使用ACARS实现飞机状态监视的数据链应用，通过飞机信息处理、消息封装、数据压缩和信息编码4个实现步骤，周期下传包含飞行参数、飞机系统状态和故障告警信息的ACARS消息。该方法间接提升了ACARS网络的信息容量，使航空公司等地面用户能够实时全面监视飞机状态。

New datalink application for aircraft condition monitoring based on ACARS

Airlines are paying more attention to monitoring its aircraft after AF447 crash and MH370 missing.Common communication and surveillance means to aircraft is analyzed.A new datalink application for monitoring aircraft condition based on ACARS(Aircraft Communication Addressing and Reporting System) is proposed.It operates aircraft information processing,message envelope,data compression and information encoding orderly,periodically transmits ACARS message including flight data,aircraft system state,maintenance and fault information.It increases the information capacity through ACARS network indirectly,which helps airlines monitor and get more flight information from its aircraft in real-time.
