Embodiment Construction

[0025] The present invention will be further described in detail through the drawings and examples below.

[0026] The space station is different from the manned aircraft that flew for a short period of time in the past. It is required to operate in orbit for 15 years and has long-term manning. The power system is the heart of the aircraft. For failures that affect the safety of astronauts or may cause platform failure, they need to be quickly discovered and responded in real time. , emergency treatment. Therefore, it is necessary to provide a set of autonomous health management system and management method suitable for the long-term operation of the space station. The autonomous health management system can ensure timely detection and diagnosis of faults outside the measurement and control area, and astronauts can carry out disposal work in real time. Fault information can be downlinked to the ground, and in-depth investigation and detailed disposal can be carried out; instea...

Abstract

The invention provides an in-orbit autonomous health management system and management method for a long-life power supply system for space. The system comprises a health management unit, a data transmission computer and a power supply system ground fault diagnosis system, the health management unit comprises a control subsystem self-detection unit, a sun-facing orientation subsystem self-detectionunit and a power manager. The autonomous health management system can ensure that faults can be found and diagnosed in time outside a measurement and control area, astronauts can carry out disposal work in real time, fault information in the measurement and control area falls to the ground, and deep troubleshooting and detailed disposal can be carried out; a traditional human-oriented ground monitoring mode is changed, faults can be autonomously detected and diagnosed through the design of the autonomous health management system, the phenomena of misjudgment and missed judgment are reduced, the burden of ground flight control personnel is relieved, and long-term stable operation of a power supply system is maintained.

Description

technical field [0001] The invention belongs to the field of on-orbit autonomous health management of space vehicles, and relates to an on-orbit autonomous health management system and management method of a space long-life power supply system. Background technique [0002] According to my country's three-step strategic plan for the development of manned spaceflight, in the third stage, my country will build a long-term manned space station. The space station is different from any previous in-orbit aircraft. It is a long-life, high-reliability, maintainable, high-voltage A high-power manned aircraft, in which the power supply system is the "heart" of the entire space station, responsible for supplying power to the electronic equipment of the entire space station. In the past, the power supply system of manned aircraft generally only had a separate power supply and distribution function, and did not have the ability of on-orbit autonomous health management. The space station ...
