Problems solved by technology

[0003] At present, once an abnormality occurs on most satellites in orbit, post-event data analysis is often performed through the delayed telemetry stored in the on-board computer or the real-time telemetry stored in the storage module. The 1553B bus data cannot be monitored, and the on-orbit fault diagnosis and analysis The positioning has a great influence, and it is impossible to quickly and accurately locate the problem and analyze the mechanism

Embodiment Construction

[0019] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0020] The present invention aims at the current situation that such data cannot be analyzed and applied in the whole satellite test and the in-orbit stage, and proposes a spacecraft 1553B bus word monitoring data analysis application method, which can analyze the MT mode bus data, and then complete data query, Analysis, comparison and other applications realize the on-board bus monitor.

[0021] In specific implementation, for example, depending on the comprehensive test task of a certain satellite, the spaceborne multifunctional platform storage module records the messages transmitted on the 1553B bus according to the 1553B chip bus word monitoring (Word Monitor) function (ie MT mode) , each time a message word on the bus is received, an ident...

Abstract

The invention provides a spacecraft data analysis application method, which comprises the following steps of: monitoring a combination of identification words and bus message formats by bus words, carrying out inter-frame iterative search on original data of a spacecraft according to a remote terminal online identifier, and splicing a message of a bus communication protocol and a message of a word monitoring mode, so that merging and separation of bus message types are realized, and satellite-borne binary code streams are expressed in a logic form of character feature data.

Description

technical field [0001] The invention relates to an application method for analyzing data of a spacecraft, in particular to an application method for analyzing data of monitoring 1553B bus words of a spacecraft. Background technique [0002] The spacecraft widely adopts the on-board data communication mode of the 1553B serial data bus, and the bus data accounts for more than 80% of the data volume of the satellite platform. The problems to be located and solved through the bus monitor account for about 1 / 3 of the problems in the entire satellite test, so the bus monitor is an indispensable core device for the satellite comprehensive test. [0003] At present, once an abnormality occurs on most satellites in orbit, post-event data analysis is often performed through the delayed telemetry stored in the on-board computer or the real-time telemetry stored in the storage module. The 1553B bus data cannot be monitored, and the on-orbit fault diagnosis and analysis Positioning has ...
