Universal avionics bus test analysis method and device

Abstract

The invention discloses a universal avionics bus test analysis method and a universal avionics bus test analysis device. An interface control document (ICD) management module stores an edited ICD file into a database; an equipment mapping module obtains a mapping relationship between a receiving medium and the ICD file, and stores the mapping relationship in the database; and a data acquisition and analysis module dynamically generates a data block according to the mapping relationship, and finishes management over the data block. By the method and the device, ICDs of various buses can be edited, so that the universality of ICD edition and the reusability of codes are ensured; and the ICD file can be flexibly mapped with the bus data receiving medium, so that the flexibility of software and hardware design is improved.

Description

technical field [0001] The invention relates to an aviation bus test and analysis method, which belongs to the technical field of aviation electronic bus test. Background technique [0002] During the test process of the aircraft avionics system, the test parameters need to be displayed in real time or recorded in a file according to the specific needs of the R&D personnel, so as to facilitate real-time or post-analysis of relevant parameters. Therefore, in the bus test process, the collection and analysis of relevant parameters is necessary. [0003] Different data transmission buses such as 1553B bus, ARINC429 bus, and RS422 / 485 bus have different ICD (Interface Control Document, interface control file) definition forms, and the ICD editing interface is also different. For example, 1553B bus has no data label parameters, and The ARINC429 bus has; in the prior art, the data sign bit in the ICD file has only one bit, which cannot meet the requirements of all data, because t...

[0003] Different data transmission buses such as 1553B bus, ARINC429 bus, and RS422 / 485 bus have different ICD (Interface Control Document, interface control file) definition forms, and the ICD editing interface is also different. For example, 1553B bus has no data label parameters, and The ARINC429 bus has; in the prior art, the data sign bit in the ICD file has only one bit, which cannot meet the requirements of all data, because the data may have one, two sign bits, or no sign bit

In addition, during the data transmission process, for the 1553B bus, the ICD corresponding to each RT (Remote Terminal, remote terminal) must be defined before the test. If the ICD corresponding to a certain RT is changed, the analysis method must be changed accordingly; For the ARINC429 bus, each channel also corresponds to an ICD file. If the ICD file of a certain channel is changed, the analysis method must be changed accordingly. This is not flexible enough for the software and hardware, which will inevitably lead to the analysis method of the bus test. Poor reusability, that is, the mapping of ICD changes, and the analysis method needs to be changed
