Embodiment 1

[0035] like figure 1 shown, figure 1 This is a structural block diagram of the ACARS airborne system provided in Embodiment 1 of the present invention.

[0036] ACARS system includes airborne system, ground control system and communication base station. The communication base station realizes the communication between the airborne system and the ground control center.

[0037] The airborne system is installed on the aircraft, including the communication unit, the communication management unit, the integrated modular avionics and the control / display unit.

[0038] The communication between the ACARS airborne system and the ground control center is realized through one of the three air-ground communication sub-networks of VHF, satellite and HF. VHF communication is the cheapest way of communication, but it cannot be transmitted across the ocean due to the limitations of its straight-line transmission; satellite communication is transmitted through the INMARSAT satellite netwo...

Embodiment 2

[0043] like figure 2 , image 3 shown, figure 2 A flowchart of a method for fault diagnosis and health management of an ACARS airborne system provided in Embodiment 2 of the present invention, image 3 It is a schematic flowchart of analyzing and judging the operation state information of the communication unit and the operation state information of the communication management unit by the integrated modular avionics device provided in Embodiment 2 of the present invention.

[0044] This embodiment discloses a method for fault prediction and health management of the ACARS airborne system described in Embodiment 1, including the following steps:

[0045] S1. The communication unit periodically sends the operation state information of the communication unit itself to the communication management unit. The communication unit operation state information at least includes the temperature, current, voltage, and antenna state information of each module of the communication unit, ...

Abstract

The invention discloses an airborne Aircraft Communication Addressing and Reporting System (ACARS) and a malfunction diagnosis and health management method thereof. The airborne system comprises a communication unit, a communication management unit, comprehensive modularized avionic equipment and a control/display unit. The comprehensive modularized avionic equipment comprises a data acquisition module, a data processing module, a status monitoring module and a health evaluation and malfunction diagnosis module. The airborne system communicates with a ground control center to achieve real-time information transmission between a plane and the ground; and meanwhile, the airborne system is provided with the data acquisition module, the data processing module, the status monitoring module and the health evaluation and malfunction diagnosis module, the Aircraft Communication Addressing and Reporting System (ACARS) can be subjected to health condition monitoring and malfunction diagnosis, and therefore the safety and the reliability of the Aircraft Communication Addressing and Reporting System (ACARS) are further improved, and the flight safety is ensured.

Description

technical field [0001] The invention relates to the technical field of avionics, in particular to an ACARS airborne system and a fault diagnosis and health management method thereof. Background technique [0002] Aircraft Communications Addressing and Reporting System (ACARS) is a digital data link system that transmits short messages via radio or satellite between aircraft and ground stations, widely used in air traffic services and airline operations Control, as an important means of communication and information transmission, such as aircraft operation control and service, aircraft / engine remote status monitoring and fault diagnosis, and ground service, is the most widely used and widely used data link system in the field of civil aircraft communication. The ACARS system is very important to aviation flight safety. The current ACARS system can realize real-time information transmission between the aircraft and the ground, but cannot monitor the health status and fault dia...
