A kind of distributed attack-resistant domain management and control method and system for giant constellation, the present application relates to satellite constellation management and control technical field, the present application aims at solving the problem of cooperative management and control and attack-resistant resilience maintenance of multi-layer heterogeneous giant constellation in dynamic topology environment.Technical points: the present application takes the management and control node satellite as core, combines with the cluster head satellite and ordinary satellite in domain, forms distributed management and control domain structure.The structure undertakes cross-orbit communication switching and distributed cooperative management and control function, effectively deals with the cooperative management and control challenge brought by the difference of multi-orbit satellite in operation cycle, communication topology and communication time delay;Introduce multi-element maximum entropy trust model: based on fuzzy C clustering algorithm and maximum entropy principle, construct dynamic trust evaluation system, and comprehensively quantitatively analyze the trust degree of distributed nodes.Through real-time identification of high-risk nodes and implementation of isolation measures, significantly reduce the interference of malicious satellite to inter-satellite data transmission, improve system security.The present application realizes the efficient cooperative management and control and attack-resistant ability enhancement of multi-layer heterogeneous giant constellation, provides key technical support for stable operation of giant constellation under complex threat environment.

This invention relates to a rubber head thinning fixture and its application method, comprising a movable platform, on which a rubber head holding plate, two racks, and two movable frames are arranged; a rubber head roller is arranged above the rubber head holding plate, and both ends of the rubber head roller are mounted on the movable frames via movable components. Gears are fixed to the ends of the rubber head rollers and mesh with the racks; a crank handle is provided at either end of the rubber head roller as a driving component; in use, the crank handle is cranked forward, and the gears drive the rubber head roller to rotate while moving forward along the racks, crushing the rubber head; after reaching the limit position, the crank handle is cranked in the opposite direction, driving the rubber head roller to return to its original position; this invention achieves reciprocating rolling thinning of the rubber head through a purely mechanical structure, with a simple and stable structure, requiring no electric drive, and can be flexibly used between different machines, effectively solving the problem of rubber heads being too large to be directly crushed.
