Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The core idea of ​​the satellite abnormal state detection system of the present invention is: the satellite telemetry parameters have a certain change law in normal state, and by comparing the parameter to be detected data with the parameter sample data in the normal state, the satellite telemetry parameter that does not rely on expert knowledge can be realized. Detection and extraction of abnormal states.

Abstract

The invention discloses a satellite abnormal condition detection system based on telemeasuring data. The system comprises a telemeasuring data preprocessing unit, a relevance calculation unit, an extreme point extraction unit, an abnormal condition extraction unit, a telemeasuring parameter original database, a relevance threshold database and an extreme point threshold database. The system fully utilizes a historical telemeasuring parameter sample, combines satellite telemeasuring parameter data characteristics and a data change law, compares the telemeasuring data in a period with relevance of the historical sample data and the extreme point errors, achieves satellite abnormal condition detection and extraction through a small amount of historical data without design knowledge, solves the problem that the existing abnormal state detection method depends on experiential knowledge of experts and abnormal change of telemeasuring parameter in the normal range cannot be solved through the existing detection method, and provides an effective and visual method and tool for satellite managers to analyze the satellite state change.

Description

technical field [0001] The invention relates to a satellite abnormal state detection system, in particular to a satellite abnormal state detection system based on telemetry data, and belongs to the technical field of fault prediction and health management. Background technique [0002] Telemetry data is an important basis to reflect whether the satellite's operating status is normal or not. Combined with telemetry data, satellite operation managers, domain experts and designers can accurately detect abnormal satellite operation, analyze abnormal causes, and improve satellite design, thereby improving the overall design and operation management level of satellites. The satellite abnormal state detection method and device based on telemetry data mainly use the historical telemetry data of the satellite, combined with recent measurement and control events and state quantity changes, and complete the satellite state abnormality detection by comparing the difference between the d...
