Embodiment Construction

[0033] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0034] Such as figure 1 , figure 2 As shown, the present invention has designed a kind of method of flight management system two-plane synchronization, determines the synchronous / asynchronous mode and its state of two-plane by cross-communication test and flight control panel FMM source, by adopting based on priority data processing mechanism, The method of combining real-time data processing and long-period data processing meets the needs of real-time large-capacity data communication of dual-plane synchronous data. The system includes two flight management modules (FMM), one of which is defined as the first flight management module ( FMM1), the other is defined as the second flight management module (FMM2).

[0035] (1) Define that the system has two operating modes: synchronous mode and non-synchronous mode. In the synchronous mode, the first fli...

Abstract

The invention discloses a double-machine synchronization method for a flight management system. The method comprises the following steps: (1) initializing the modes and the states of a first flight management module and a second flight management module; (2) performing cross communication test on the first flight management module and the second flight management module; (3) determining the synchronization mode of the first flight management module and the second flight management module; (4) determining the main state and the slave state of the first flight management module and the second flight management module; (5) completing data synchronization according to the corresponding state. The method is clear in step and likely to project implementation. For double-machine configuration of the flight management system to a flood dragon 600 aircraft or other civil transporting aircrafts, the requirements on the redundant management of the flight management system and the reliability of the system are met, and the method has important actual application significance.

Description

technical field [0001] The invention belongs to the technical field of flight management systems, in particular to the technical field of dual-aircraft synchronization of flight management systems. Background technique [0002] The Jiaolong 600 aircraft is a new type of large-scale fire fighting / water rescue amphibious aircraft developed and manufactured by my country. It has been incorporated into the national emergency rescue aviation system and is used for forest fire fighting and water rescue tasks. At the same time, through improvement and modification, it can be used for other purposes such as passenger and cargo transportation, resource detection, marine environment monitoring and protection. [0003] The flight management system (abbreviation: FMS) function module is an important component module of the Jiaolong 600 aircraft avionics system, which provides functions such as integrated navigation based on multi-sensors, navigation database management, flight plan mana...
