Embodiment 2

[0097] figure 2 is a structural block diagram of a data set filling system according to an embodiment of the present invention, such as figure 2 As shown, the system includes:

[0098] The acquiring module 20 is configured to acquire target message information.

[0099] Optionally, the target message information includes: message size and message type.

[0100] Specifically, the ARINC664 message MSGI information of a resident application is counted, the message size of a certain message MSGI is counted, which is recorded as MessageSizeI, and the message protocol type is counted as MessageProtocolTypeI. Statistics of the dataset information of each ARINC664 message. The data set J in MSGI is recorded as DataSetIJ, the offset of the data set DataSetIJ relative to the start bit of the message is recorded as ByteOffsetWithinMsgIJ, the size of the DataSetIJ data set is recorded as DataSetSizeIJ, and the offset of the FSB corresponding to DataSetIJ relative to the start bit of ...

Abstract

The invention discloses a data set filling method and system. The method comprises the following steps of acquiring the target message information; obtaining a data set filling mode according to the target message information; filling the data set according to the data set filling mode; and performing data primitive filling on the filled data set. According to the present invention, the technicalproblems of low IMA system integration speed and high integration cost caused by information loss in the prior art are solved.

Description

technical field [0001] The present invention relates to the field of avionics, in particular to a data set filling method and system. Background technique [0002] In the field of aerospace control systems, the integrated modular avionics system (IMA, hereinafter referred to as IMA) provides aircraft core network, communication protocol conversion and core computing resources for each system of the aircraft, ensuring the communication and Processing is fast and reliable. At present, IMA generally adopts the avionics full-duplex switched Ethernet (AFDX) that meets the ARINC664 protocol as the communication method of the core network. During the integration process of the aircraft avionics system, it is necessary to clearly define the communication interface of each aircraft and form an interface control document (ICD). Clarify the structure of the messages transmitted between the various systems of the aircraft. Among them, Functional Data Sets (FDS) is a method of aggregat...
