Satellite discharge depth over-limit diagnosis and recovery test method

Abstract

The invention discloses a satellite discharge depth over-limit diagnosis and recovery test method. A power supply controller simulator and a storage battery interface management unit simulator are used as ground simulation equipment for a fault test, input parameters of a fault trigger condition are therefore provided for the test, corresponding service support equipment is selected as satellite discharge fault detection, discharge depth over-limit faults are divided into a whole-satellite second-level fault, a whole-satellite fourth-level fault, a parallel fault and a coupling fault, manufacturing schemes corresponding to the different types of faults are made according to fault mechanisms, and the satellite discharge depth over-limit diagnosis and recovery test is completed. Thus, the simulator modifies determination parameters of power management software or modifies parameter determining manners of the software to simulate the faults, performance decrease degree and using disc in the actual battery test process are reduced, the service life of the battery is prolonged, the test risk is reduced, and the satellite security is ensured.

Description

Technical field [0001] The invention relates to a method for diagnosing and recovering satellite discharge depth exceeding limit. Background technique [0002] Satellite battery packs are important energy storage equipment for satellites and one of the life support systems for satellites in orbit. Once a failure occurs, if it cannot be detected or dealt with in time, it may cause irreversible damage to the satellite battery pack, resulting in catastrophic consequences for the satellite. In order to prevent the occurrence of this event, the satellite has designed a depth-of-discharge over-limit diagnosis and recovery strategy, which is mainly used to detect the depth of discharge of the battery pack and divide the depth of discharge of the battery pack into two fault levels. When any fault level is reached Both will report to the police in time. At the same time, the satellite will make corresponding troubleshooting based on the fault level. This ensures that in the event of a ...

Problems solved by technology

[0004] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, in view of the current satellite ground test process, the satellite failure occurs randomly or does not occur, it is impossible to verify the discharge depth of the battery pack beyond the limit diagnosis and recovery strategy, and it is impossible to realize Carry out a comprehensive verification of multi-layer fault diagnosis and recovery strategies with other subsystems, propose a method that can cause faults to occur at a specific time and in a specific environment according to needs, and realize a comprehensive verification of the satellite discharge depth exceeding the limit diagnosis and recovery strategy
