Problems solved by technology

[0003] Many existing aircraft use FANS applications in avionics equipment, while FMS exists as an independent device, and the system integration level is not high. FMS provides a large amount of data for many avionics equipment, and the connection is intricate. It is necessary for system troubleshooting and system space design. caused a lot of trouble

Embodiment 1

[0032] Such as Figure 1-2 As shown, the present invention includes an interface realization system between FANS application and FMS, including the future air navigation system FANS application and flight management system FMS based on the integrated modular avionics system IMA architecture, and the future air navigation system FANS application and flight management system The FMS is located in two partitions of a general processing module GPM in the integrated modular avionics system IMA chassis, and the two partitions communicate through inter-partition communication or through the avionics full-duplex switching Ethernet AFDX network.

[0033]This solution is different from the existing technology. The FANS application of the future air navigation system and the flight management system FMS are not independent terminals, but are located in two partitions of a general processing module GPM in the IMA chassis of the integrated modular avionics system. The two partitions They c...

Embodiment 2

[0035] The present embodiment is preferably as follows on the basis of embodiment 1: the interface between the future air navigation system FANS application and the flight management system FMS includes the following five layers:

[0036] Physical layer: It is the bottom layer of the system, using the avionics full-duplex switching Ethernet AFDX bus to realize the original data transmission;

[0037] Data link layer: Located between the physical layer and the network layer, it provides services to the network layer through the MAC system on the basis of services provided by the physical layer;

[0038] Network layer: between the transport layer and the data link layer, manages data communication in the network, thereby providing end-to-end data transmission services to the transport layer;

[0039] Transport layer: UDP protocol is used for data transmission and data control;

[0040] Application layer: use simple network management protocol SNMP and FANS / FMS information excha...

Embodiment 3

[0048] The method for implementing the interface between the FANS application and the FMS. The FANS application of the future air navigation system sends a data request instruction to the flight management system FMS. The FANS application sends the response data, the specific data requested is defined by the management information base MIB, the method of requesting data is defined by the FANS / FMS information interaction FFIB, and the interactive message of the requested data is realized by the Simple Network Management Protocol SNMP primitive.

[0049] The ways of requesting data include periodic request data and event trigger request data. In this method, the simple network management protocol SNMP and the FANS / FMS information interaction FFIB application realize the data interaction between the FANS application and the FMS, and the FANS / FMS information interaction FFIB is based on the contract data access method between Client and Server, which is different from the existing ...

Abstract

The invention discloses a system and method for realizing the interface between the FANS application and the FMS, including the FANS application and the flight management system FMS of the future air navigation system based on the integrated modular avionics system IMA architecture, the FANS application and the flight management system of the future air navigation system The FMS is located in two partitions of a general processing module GPM in the integrated modular avionics system IMA chassis, and the two partitions communicate through inter-partition communication or through the avionics full-duplex switching Ethernet AFDX network. The present invention uses the above principles and based on the interface, the data of the flight management system FMS can be sent to the AFDX network, so that all devices connected to the network can access these data if necessary, and the use is more convenient and simple.

Description

technical field [0001] The invention relates to the field of avionics communication interface, in particular to a system and method for realizing the interface between FANS application and FMS. Background technique [0002] Integrated Modular Avionics System (Integrated Module Aviomics, IMA, modularized integrated avionics system) is the comprehensive architecture of avionics system used by typical aircraft in service. The avionics system of B787, A380 and COMAC C919 all adopt IMA architecture . The B787 aircraft adopts the common core system (Common Core System, CCS) as the nerve center of the aircraft, uses the 10 / 100Mbps AFDX bus as the data transmission "central" of the aircraft avionics system, and uses the remote data concentrator (Remote Data Concentrator, RDC) as the Data acquisition and data conversion equipment to achieve a high degree of integration of avionics and aircraft functions. [0003] Many existing aircraft use FANS applications in avionics equipment, w...
