基于知识辅助和OOOI报文的飞机航段识别系统

THE AIRCRAFT LEG IDENTIFICATION SYSTEM BASED ON KNOWLEDGE-AIDED AND OOOI REPORTS

针对航班多航段运行的实际过程中,由于人为因素、设备故障等原因导致OOOI报文异常的情况,提出一种基于知识辅助和OOOI报文的飞机航段识别方法。该方法借助专家系统的设计思路,选定报文的关键参数作为航段推理的事实依据,以机载燃油油量、预计到达时间和位置报等作为辅助知识,利用规则表示法整理了一套基于知识辅助和OOOI报文的航段识别逻辑及知识库。以真实报文为例,分析报文漏发的情况并进行航段识别。结果表明,利用航段改变、航段不变、报文无效和航段撤销等判别结果,该系统可有效地实现飞机航段识别。

Aiming at the abnormal situation of OOOI reports caused by human factors and equipment failure in the actual process of flight operation,a method of aircraft leg identification based on knowledge-aided and OOOI reports is proposed.By using the design idea of the expert system,the report key parameters were selected as the factual basis of flight leg reasoning.The airborne fuel volume,estimated time of arrival and position report were used as auxiliary knowledge,and a set of flight leg identification logics and knowledge bases based on knowledge-aided and OOOI reports were sorted out by the rule representation method.Taking the real report as an example,the situation of report missing was analyzed to identify the flight leg.The results show that the system can effectively realize the flight leg identification by using the results of the flight leg change,the flight leg unchanged,the report invalid and the flight leg revocation.
