Power supply and distribution reconfigurable control system and method oriented to batch flight verifications

Abstract

The invention relates to a power supply and distribution reconfigurable control system and method oriented to batch flight verifications. Aiming at the problems of the failure and dynamic power demandchange of a power supply and distribution unit in the process of in-orbit batch flight verification of a future component, the cross recombination output control of power supply and distribution output is implemented on a power supply and distribution output terminal by using four groups of magnetic latching relays; and in the process of an aerospace in-orbit flight test, the in-orbit dynamic reconfiguration for the power supply output control of the power supply and distribution unit can be implemented through cross recombination according to the dynamic power requirement of a test unit andthe task fault-tolerant control need. With the power supply and distribution reconfigurable control system and method oriented to the batch flight verification disclosed by the invention, the flexibility and expansibility of the power supply and distribution output control are improved, meanwhile the reliability of the power supply and distribution output is enhanced, and a key technical support is provided for the future in-orbit batch flight verification.

Description

technical field [0001] The invention relates to a reconfigurable control system and method for power supply and distribution oriented to batch flight verification, specifically aiming at the power supply and distribution requirements of future component on-orbit batch flight verification, on the basis of controlling the cost of hardware design, it provides A low-cost, high-reliability reconfigurable control method for power supply and distribution based on centralized power supply is proposed. Background technique [0002] A large number of domestic aerospace components and components are yet to undergo on-orbit flight tests to verify their applicability to the space environment. In the future, on-orbit flight verification will become an important way and effective means to quickly improve the maturity of domestic aerospace components. my country will also build the first autonomous space station around 2022. In the next ten years, batch flight verification of components in ...

Problems solved by technology

[0014] With the rapid increase in the number of spacecraft in orbit, the ground measurement and control load and pressure are getting heavier and heavier. For deep space exploration such as "Galileo", the measurement and control period is as long as more than one hour. Therefore, traditionally rely on ground measurement and control to complete the power supply and distribution of on-orbit aircraft. The maintenance method can no longer meet the mission requirements, and it is urgently needed for the spacecraft to independently control the power supply and distribution output and monitor in real time to realize the ability to work autonomously;
