Abstract
An embodiment of the present invention discloses a monitoring and repair method for a planetary exploration parachute system. The monitoring and repair method includes: sensing an impact force of dust and generating a sensing signal by a sensor; receiving the sensing signal by an electrode in a fuse; and when the sensing signal is greater than a preset threshold, fusing a safety wire in the fuse; after the safety wire is fused, changing a spring in the fuse from a compressed state to a natural state to generate tension; and rotating a repair rod under an action of the tension to drive a folding piece to be changed into an unfolded state from a folded state, thus realizing precise evaluation of impact damage of dust particles to a parachute body, closed-loop control and real-time self-repair.
