Rule-based satellite telemetry data analysis system

Abstract

The invention discloses a rule-based satellite telemetry data analysis system. The system comprises a rule editing system and an online analysis subsystem, wherein the rule editing system serves as aninput port of diagnosis rules to provide a graphic rule editing mode and a script rule editing mode and write association judgment diagnosis rules, condition judgment diagnosis rules, mode judgment diagnosis rules, mathematic and logic operation diagnosis rules and other diagnosis rules for one-dimensional telemetry and multi-dimensional telemetry through associated satellite telemetry parameters, and the rule editing system is provided with a rule base; and the online analysis subsystem reads the rules compiled by a user from the rule base and loads the rules into an analysis and judgment process, the analysis process performs analysis and diagnosis on real-time telemetry data according to the rules by receiving telemetry physical quantity data from the Internet, the judgment result is written into a result database, and the judgment result is sent out through the Internet. Through the system, a satellite test data judgment rule establishing tool is provided, and therefore the user can establish and modify the rules conveniently and quickly.

Description

technical field [0001] The invention relates to a satellite telemetry data analysis system, in particular to a rule-based satellite telemetry data analysis system. Background technique [0002] With the rapid development of my country's aerospace industry, the number of satellites in our country has increased significantly. Satellites have become an important means of meteorological monitoring, land and resources surveys, intelligence acquisition and battlefield situation estimation. At the same time, in order to meet the increasing functional requirements in the process of satellite applications , the system design of the satellite is becoming more and more complex, no matter in the process of ground testing or on-orbit data monitoring, the traditional telemetry data analysis system can no longer fully meet the requirements of telemetry data analysis.

[0002] With the rapid development of my country's aerospace industry, the number of satellites in our country has increased significantly. Satellites have become an important means of meteorological monitoring, land and resources surveys, intelligence acquisition and battlefield situation estimation. At the same time, in order to meet the increasing functional requirements in the process of satellite applications , the system design of satellites is becoming more and more complex. No matter in the process of ground testing or on-orbit data monitoring, the traditional telemetry data analysis system can no longer fully meet the requirements of telemetry data analysis.

[0003] At present, the existing satellite telemetry data analysis has the following deficiencies: 1. The online analysis of satellite telemetry data relies too much on threshold judgments, and cannot give timely alarms for associated faults or complex faults; 2. The real-time analysis capability of satellite telemetry data is not strong. Most of them rely on telemetry playback and post-event analysis; 3. The current on-orbit monitoring system has insufficient data analysis capabilities, single monitoring methods, and insufficient fault alarm capabilities. It is urgent to enhance on-orbit fault detection capabilities and improve fault handling response speed
