Research On Land-to-air Calling Method Based On AIDL Language

The field of civil aviation safety has always been a very important research topic.In recent years,the rapid development of the air transport industry has facilitated people’s travel.Air transport has gained popularity among people.At the same time,air traffic has increased drastically,and available airspace has become extremely crowded.As a result,civil aviation safety is also facing More and more serious challenges.At this stage,China’s aircraft operations,under normal circumstances,are operated in accordance with the flight plan prepared by the dispatcher.However,there may be unforeseen unexpected situations in the route,and each pilot will have its own unique aircraft.The way the original flight plan does not completely determine the operation of the entire aircraft.At present,modern air traffic management systems mainly use ground-to-space information exchanges between radio and telephone calls between controllers and pilots to clarify the current operational status of the aircraft and the following flight target instructions.However,due to radio and telephone air,land and air,The possible instability of call communication and possible obstacles in language communication have largely contributed to the ambiguity of information transmission,which has greatly affected the operational safety of aircraft.In this paper,the aircraft intent description language(AIDL)is applied to land-space conversations based on the land-air call method of intention information and the application of intent information in air traffic control.Based on formal language theory,AIDL instructions are organized,instruction database is established,instructions are defined and defined,AIDL language rules are studied,search tree is used to generate aircraft intention information,and finite state machine(Deterministic finite The Automaton,DFA)physical model method identifies AIDL language instructions,and analyzes the correspondence between existing radio land and air call instructions and AIDL control instructions.By studying state variables in flight motion,AIDL instructions are associated with state variables.,In order to achieve command-based land and air call command methods;finally through the establishment of land and air call visualization window,to build a land and air call system platform with command transmission as the main means to reduce the inaccuracy of information transmission caused by the understanding error of voice communication transmission.,and put forward a land-air conversation process instance to verify the effectiveness of the system.
