On-orbit fault detection and maintenance method based on inspection robot

Abstract

The invention discloses an on-orbit fault detection and maintenance method based on an inspection robot. First of all, the inspection robot is sent to a target satellite through a rescue satellite and is absorbed at an absorption surface at the surface of the target satellite, then, the inspection robot is enabled to arrive at a satellite surface test interface position of the target satellite, a control center computer is connected with the target satellite, finally, through the control center computer of the inspection robot, handshake signals are sent to the target satellite, return signals of each device of a satellite system are received, the work state of each subsystem of the target satellite is determined, and faults are eliminated through initializing or taking over the target satellite. Compared to the prior art, the method provided by the invention has the following advantages: the robot is used for inspection and detection maintenance on the surface of the satellite, the disadvantage in the prior art is overcome that when the satellite faults are determined through analyzing remote measuring information transmitted back by the satellite, if a measuring and control system generates faults, the remote measuring information cannot be obtained for fault analysis, and physical fault restoration of the target satellite can be realized.

Description

technical field [0001] The invention relates to a satellite on-orbit fault detection and maintenance method, in particular to a patrol robot-based on-orbit fault detection and maintenance method. Background technique [0002] At present, space technology has entered a period of rapid development. It is estimated that by 2020, the number of Chinese satellites in orbit will exceed 200, and these satellites are mainly distributed in GEO, MEO and SSO orbits, including earth observation, communication, navigation, electronic reconnaissance and Countermeasures, early warning and other application satellites. These satellites are expensive, complex in structure, and have a long life cycle. Once a failure occurs during the life cycle, it will cause huge economic losses. Among these satellite failures, some of them can be restored by starting system redundancy backup or ground command switching through the measurement and control link, but the other part of the failure cannot be rep...
