Autonomous hierarchical process control guiding method for satellite system

Abstract

The invention relates to a method for controlling the automatic grading guide process of a satellite system which includes the following steps: firstly, a host computer carries out full self detection, degrading self detection and core self detection in turn; if the self detections are not successful, the host computer is out of action and is automatically switched to a spare machine; if the selfdetections are successful, judging whether to have the remote-control command of a loading procedure or not, if not, then reading a pointed FLASH / EEPROM procedure to a pointed RAM; if yes, then waiting and judging whether the remote-control command is an upper remote-control code command, a remote-control assembly code command and an upper remote-control code execution command or not; respectivelystoring the upper remote-control code command into the pointed RAM, storing the pointed RAM code into the pointed FLASH / EEPROM and reading the FLASH / EEPROM procedure to the pointed RAM as well as implementing the procedure in the RAM. The method reduces the risk of the satellite system, improves the reliability, real time performance and safety of the satellite system and solves the practical problems of modifying and reinforcing the function of the satellite by controllable and programmable means when the system goes wrong and the satellite is at orbital.

Description

technical field [0001] The invention relates to a control method for the autonomous guidance process of a satellite system realized through self-inspection telemetry and remote control instructions of a host computer of a satellite management system, and belongs to the field of satellite control. Background technique [0002] At present, the traditional satellite design at home and abroad is to use the direct operation program when the satellite is powered on, and does not use a special autonomous boot program control method. When the on-board equipment fails, the satellite management system cannot take effective measures to monitor the satellite system. At the same time, partial failures cannot be isolated and processed, so only the entire on-board equipment can be isolated. In this way, full backup redundancy measures must be adopted in the design of the satellite system, which makes the design and manufacturing costs very high, resulting in a relatively high price .
