A Fast and Autonomous Fault Handling Method for Spaceborne Operating System Integration

Abstract

The invention discloses a quick fault auto-processing method for integration of a satellite-borne operating system. The method comprises the following steps of: (1) allocating a fault code for each fault, defining a fault processing function by a user to serve as a record item, and performing organization by a hash table to realize quick insertion and quick search taking the fault code as a key word; and (2) in a running process of the satellite-borne operating system, when a kernel detects a fault, sending the fault code to a message queue, obtaining a fault message through the message queue, performing search in the hash table according to the fault code, obtaining a detailed result of fault diagnosis, and performing processing. The invention provides a fault diagnosis and processing mechanism of an application layer, which can effectively solve the fault problem that processor interruption or trap cannot be identified and processed in the system by adopting software means.

Description

technical field [0001] The invention relates to a fast and autonomous fault processing method integrated with an on-board operating system, which belongs to the field of highly reliable and highly credible embedded operating system software. Background technique [0002] The operating system is an important part of the onboard computer software. Since the onboard computer has extremely high reliability requirements, the operating system needs to have high fault tolerance and support rapid autonomous fault handling and repair at the software level. [0003] In the traditional on-board operating system, the fault (abnormal) processing is to use the interrupt or trap of the processor hardware, so as to enter the exception service program to complete the fault processing. Although this method is practical and effective, it has two limitations: one is that it needs hardware support, if the fault that occurs when the software is running cannot cause a processor interrupt or trap, ...
