| 摘 要： | 当前民航系统使用的AFTN（航空固定电信网）报文存在格式、内容、数据不规范的问题，致使FDP系统（飞行数据处理系统）报文识别率不高。本文针对FPL（领航计划报）报文进行预处理，对于重复性FPL报文，采用直接查询调用历史数据的方法。而新报文则根据FPL报文标准进行规范性判断和纠正处理，并将处理结果保存为历史数据作为下一轮处理的参考数据。实验证明，原本FDP系统无法识别的FPL报文经过预处理后再进入FDP系统，FDP系统识别率可以达到75％以上，FDP系统的FPL报文识别率得到了显著的提高。

| Abstract: | The current AFTN telegrams＇ lacking standardization for format, contents and data, restdted in low telegram discrimination of Flight Data Process System （ FDP System）, and stresses the ATC operators. The paper alines the Fhght Plan Telegram to pre-processing, for repeat FPL, directing to querying history data, and new FPL, judging its standardization according to FPL telegram standard, modifying its wrong messages, then storing the result telegram, as reference for the next FPL processing. After being pre-processed, up to 75% of wrong FPLs unknown by FDP system come to be recognized by FDP system again, FPL telegram discrimination of FDP system is improved significantly. |
