Abstract

The invention discloses a method for controlling generator tripping based on a minisatellite dual-computer system, and belongs to the field of satellite computers. According to the control method forgenerator tripping based on the minisatellite dual-computer system, dual computers are monitored by watchdogs, and the method comprises the following operations: when a host is on duty, enabling the host to regularly write data into a host FIFO and a standby FIFO; if dog bite occurs once, submitting NMI interruption, recording and rewinding the satellite computer application program, and running the satellite computer application program again; if dog bite occurs twice continuously, resetting the host system, enabling software and hardware of the host system to recover to the initial state, and enabling the program to run again; if dog bite occurs for three times continuously, powering up a standby machine, automatically transmitting data to the FIFO of the standby machine by the FIFO of the host machine after the standby machine is reset, finishing data migration after the standby machine extracts the data, and rerunning the system. According to the invention, the problem of long-timegaps in the flight mission switching process is solved.

Description

technical field [0001] The invention belongs to the field of satellite computing, in particular to a control method based on a small satellite dual-machine system cut-off. Background technique [0002] As the core component of the satellite platform system, the star computer is responsible for completing the comprehensive information processing of the satellite, managing and controlling each mission module on the satellite, monitoring the status of the entire satellite, coordinating the work of the entire satellite, and realizing various controls and settings with the payload. Complete the remote control telemetry mission of the whole star. The traditional Starworks computer adopts a dual-computer cold backup architecture and is in the working mode of always powering on. [0003] In view of the importance of the position of the star computer in the entire star, when facing a complex space environment, when the star computer has a failure mode such as a single event flip, de...
