1. A repair system for a planetary exploration parachute, comprising:
a plurality of connectors, each connector configured to fix the repair system to a parachute body of the parachute;
a plurality of folding pieces, each folding piece configured to repair a damaged part of the parachute, the folding piece having a folded state and an unfolded state, and an initial state of the folding piece being the folded state;
a plurality of repair rods, the connectors being fixed to two ends of each repair rod respectively, at least two of the plurality of repair rods being adjacent, and the folding piece being provided between the two adjacent repair rods; and
a plurality of fuses, each fuse provided in the folding piece, the fuse being configured to receive a sensing signal and generate fusing when the sensing signal is greater than a preset threshold, and the folding piece being changed from the folded state to the unfolded state after the fusing is generated in the fuse.
