Method of monitoring aircraft state through ACARS (Aircraft Communication Addressing and Reporting System) data chain

Abstract

The invention provides a method of monitoring an aircraft state through an ACARS (Aircraft Communication Addressing and Reporting System) data chain. An aircraft state monitoring application module is arranged in a communication management unit (CMU) in a software form under a system structure of using the CMU as an onboard ACARS data chain application terminal. The aircraft state monitoring application module sequentially executes the following four operations of aircraft information processing, message encapsulating, data compressing and information encoding so as to generate an aircraft state monitoring report. A data chain application module provides application services such as airline operational communication (AOC), aeronautical administrative communication (AAC) and air traffic service (ATS), and the data chain application module can manually and automatically generate an application report. An ACARS protocol module encapsulates the application report from the data chain application module and the aircraft state monitoring report from the aircraft state monitoring application module to ACARS messages and sends the ACARS messages to a communication subnet interface module. The communication subnet interface module of the communication management unit is connected with a plurality of very-high-frequency VDRs (Video Disk Recorder), satellite data units (SDU) and a plurality of short-wave HFDRs. By means of the method, a ground terminal can recover the flight process of an aircraft according to the received aircraft state monitoring report so as to monitor the aircraft state and remotely diagnose failures.

Description

technical field [0001] The invention relates to the field of aviation VHF data link, providing aircraft status monitoring through ACARS data link, and a method for real-time monitoring of aircraft flight status and fault information. Background technique [0002] Currently, the Aircraft Communications Addressing Reporting System (ACARS), which is widely used in data communications between aircraft and ground systems, is a ground-to-air data link system based on VHF, satellite communications, and shortwave data communications. Character-based ACARS data The chain was introduced into the field of civil aviation in 1978. With the help of the ACARS data link, the data of the aircraft computer system can be automatically or manually downloaded to the ground computer network, making the aircraft a part of the ground control, command and management system. The advantages of the ACARS data link are: high accuracy, strong anti-interference ability, and coordinated development with t...

AI Technical Summary

Problems solved by technology

[0006] Second, the real-time performance is not high

The position report of the aircraft operation communication service and the weather report of the aircraft meteorological data download service include part of the flight and status information of the aircraft, but both are periodic reports at the minute level, and the real-time performance is not high

ADS reports and other information provided by air traffic services are limited, only provide aircraft position information, which cannot meet the needs of aircraft status monitoring
