航空器意图描述语言的生成与识别方法研究

Generation and recognition methodology research of aircraft intent description language

针对当前航空器意图研究存在的统一性与规范性方面的问题,利用计算机形式语言文法的形式定义生成航空器意图描述语言AIDL(aircraft intent description language)的文法,根据AIDL的词法规则与句法规则实现了AIDL句型的有效组合方式,同时依据线性文法实现了AIDL句子的推导与归约。基于确定的有穷状态自动机(DFA)对AIDL的句子进行识别,自动生成与AIDL句子相对应的航空器意图信息,规范了航空器意图信息的描述,提出了空中交通管理中管制员与飞行员沟通的一种新方法,能够提高航空器意图信息获取的准确性与及时性,减少语音通信传输造成的理解误差。

The current air traffic management system is still relying on voice communication between pilots and controllers to know the aircraft intent information. But there is some instability and ambiguity in the voice communication and a flight safety hazard to a large extent. Aiming at the existing unity and specification problem of aircraft intent research, the way of computer form language grammar is utilized to define and generate the grammar of AIDL. According to the AIDL grammar rules of vocabulary and sentence, the effective way of sentence combination has been realized and the derivation and reduction of AIDL sentence is achieved based on linear grammar. The AIDL sentences are identified by DFA（deterministic finite automata）. Therefore, the aircraft intent information is automatically generated corresponding to AIDL sentence, the description of aircraft intent information is standardized and a new method of communication between controllers and pilots is brought up, as a result, the access of aircraft intent information accuracy and timeliness is improved and the possibility of incorrect comprehension of voice communication transmission error is reduced.
