Embodiment Construction

[0086] In the integrated airborne system of civil airliner maintenance and information service, the method is used to realize the storage of avionics network data, and the communication function of the ground maintenance system to obtain airborne avionics data and retrieve data.

[0087] Avionics network data storage and retrieval systems such as figure 1 As shown, it is mainly composed of four functional modules, module 100 corresponds to the ground avionics data analysis module, module 101 corresponds to the on-board data retrieval module, module 102 corresponds to the on-board data storage module and module 103 corresponds to the on-board data acquisition module.

[0088] 1. Module design

[0089] The on-board data acquisition module resides in the on-board network of the aircraft, collects data including aircraft flight status information from the ARINC429 bus, ARINC717 bus and RS422 bus, and obtains the system time when the data is received, and stores the collected data ...

Abstract

The invention belongs to avionic network technologies, and relates to an avionic network avionic data storage and retrieval system and method. The avionic network avionic data storage and retrieval system and method achieve the purpose that different data buses on an airplane store large-capacity data and the ground obtains airplane state information and retrieves airplane state information and are beneficial to improving the reliability and maintainability of the airplane in the operating process of the airplane, and the system comprises an on-airplane data acquisition module, an on-airplanedata storage module, an on-airplane data retrieval module and a ground avionic data analysis module. By acquiring and storing branching and bus types for airplane data and then by retrieving the branching and bus types, ground and on-airplane data interaction is achieved.

Description

technical field [0001] The invention belongs to avionics network technology, in particular to an avionics network avionics data storage and retrieval system and method. Background technique [0002] With the extensive application of information technology in civil avionics systems, more and more civil aircraft systems have informatization and networking functions. ARINC429 bus, ARINC717 bus and RS422 are usually used between the aircraft control domain and the information domain. The bus is used as a data transmission channel, and the systems or devices in the aircraft control domain transmit the status information of the aircraft during flight to the information domain through the ARINC429 bus, ARINC717 bus and RS422 bus. [0003] A large amount of flight status information will be generated in each sortie of the aircraft flight, and the aircraft control domain will transmit the flight status information to the information domain through the ARINC429, ARINC717 and RS422 bus...
