Dynamic routing method and system based on preset strategy and aircraft flight state

Abstract

The invention discloses a dynamic routing method and system based on a preset strategy and an aircraft flight state. At an air-ground communication management server, the method comprises the following steps: acquiring a unified strategy configuration file; acquiring flight state information of a current aircraft and state information of all wireless links in real time; according to the type of the current data transmission service and the current flight state information, obtaining a routing priority rule corresponding to the data transmission service of the type in the current flight state; according to the flight state information and the wireless link state information, screening in a wireless link configuration file to obtain an available link list, the wireless link configuration file being preset in an air-ground communication management server and configuring all wireless links of the current aircraft; and selecting one link from the available link list as a transmission link of the current data transmission service according to a routing priority rule. Through the technical scheme, safe and real-time air-ground transmission of data with different security levels and different importance is realized.

Description

technical field [0001] The invention relates to the technical field of aviation communication, in particular to a dynamic route selection method and system based on preset strategies and aircraft flight states. Background technique [0002] Civil aircraft air-ground communication is changing from traditional high frequency (HF) and very high frequency (VHF) to cockpit satellite communication (L-band), ground-air broadband communication (ATG) and broadband satellite communication (Ku / Ka band) and other IP-based Development of means of communication. At the same time, air traffic control data, airline operation data, maintenance and health management data, and passenger Internet + application data during civil aircraft flight all have real-time air-to-ground transmission requirements. At present, in air-ground communication, the safety level and importance level of data transmission services are not classified, and the dynamic variables related to the flight process of the ai...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the current air-ground communication, the safety level and importance level of the data transmission service are not classified, and the dynamic variables related to the flight process of the aircraft are not considered when selecting the route, resulting in a large gap in the air-ground communication transmission bandwidth. Under limited circumstances, the technical problem that data transmission cannot be carried out safely and in real time, the purpose is to provide a dynamic route selection method and system based on preset strategies and aircraft flight status, which solves the current problem of data transmission services in air-ground communications. The classification of safety level and importance level does not consider the dynamic variables related to the flight process of the aircraft, resulting in the technical problem that data transmission cannot be carried out safely and in real time under the condition of limited air-ground communication transmission bandwidth
