4D trajectory estimation-based real-time monitoring alarm method

Abstract

The invention discloses a 4D trajectory estimation-based real-time monitoring alarm method. The method includes the steps of: modeling a plane, using the plane as a mass point, and considering climbing, cruising and declining stages of the plane to be flying at uniform speed; using a 4D trajectory estimation model to predict a flying plan 4D trajectory of the plane; according to the predicted 4D trajectory, performing conflict calculation of flying plans of a period of time in the further, the conflict calculation adopting a simplified calculation mode provided by the invention, and receiving real-time monitoring alarm parameters based on the 4D trajectory; and obtaining alarm information according to a conflict calculation result. The method provided by the invention has a simple module, is easy to realize by a computer, and is very low in complexity of time and space.

Description

technical field [0001] The invention relates to the fields of computer application technology and air traffic control automation, in particular to a real-time monitoring and warning method based on 4D trajectory estimation. Background technique [0002] Since the 1960s, the civil aviation industry has made great progress, and its proportion in the entire comprehensive transportation system is also increasing. Especially after the reform and opening up, my country's civil aviation transportation industry has been in a state of rapid development, with an average annual growth rate of nearly 20%. The total turnover of China's scheduled flights ranks third among the contracting states of the International Civil Aviation Organization, and my country has become a veritable aviation power. [0003] On the other hand, with the rapid development of my country's national economy and the enhancement of national air defense capabilities, the number of flight missions performed by milit...

Problems solved by technology

[0004] At present, the existing real-time monitoring and alarm systems of various types of control centers at various levels in my country's military and civil aviation are not perfect, for example, they do not yet have the function of calculating mid-term conflicts, etc. The main reasons are: 1. Existing methods are complicated to calculate and realized with existing computer technology The required time and space complexity is high, which does not meet the real-time requirements of air traffic control monitoring; 2. my country's air traffic control has its own characteristics, which are somewhat different from developed countries such as the West. The existing foreign systems or methods are not suitable for direct use
