Problems solved by technology
[0003] At present, the existing methods for aircraft air conflict resolution are mainly based on a series of assumptions to establish a mathematical model for the air conflict problem, and use modern optimization algorithms to give the answer to the problem without engineering the problem. Practical and feasible processing methods; in addition, most of the current research does not consider the performance of the aircraft and the calculation difficulty of the algorithm. For the existing problems, a device that is simple to calculate and can be combined with existing models is needed. method of processing

The invention discloses an air navigation and conflict resolution method based on an oriented cellular automaton. The air navigation and conflict resolution method based on the oriented cellular automaton involves an airspace database module, an automatic signal broadcasting module, a receiving module, a data processing module and a display and interaction module and specifically comprises the steps that the airspace division size is determined according to an ADS-B system, an airspace model is established, and with a navigation aircraft as the center, a coordinate system is established by simulating the airspace. According to the air navigation and conflict resolution method based on the oriented cellular automaton, existing airborne equipment is utilized, a movement rule of the oriented cellular automaton is established based on the ADS-B technology, namely the aircraft automatically broadcasts the positioning information generated by an airborne satellite-based navigation and positioning system, the airspace is simulated through the oriented cellular automaton, and a navigation and conflict resolution path of the aircraft is provided according to operating and updating of the cellular; the method is simple and effective, and the flight safety performance of the aircraft can be improved greatly.
Description
technical field [0001] The invention belongs to the field of low-altitude navigation and air conflict relief, and mainly relates to an air navigation and conflict relief method based on directed cellular automata. Background technique [0002] With the rapid development of air traffic transportation, the current air traffic management system has been difficult to meet the needs of the growing air traffic flow. With the rapid development of national general aviation and the great development opportunities brought by the opening of low-altitude airspace, general aviation flight safety issues more and more prominent. Some airlines and private jets have objective factors such as small scale, weak foundation, and poor safety foundation. Especially in some remote and oceanic areas, ground navigation equipment is lacking, and a navigation equipment and navigation system with high precision and easy to use is needed. [0003] At present, the existing methods for aircraft air confli...
