Method of monitoring aircraft state through ACARS (Aircraft Communication Addressing and Reporting System) data chain
ActiveCN102930748AComprehensive collectionImprove real-time performanceAircraft traffic controlData compressionAviation
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.
