An embedded system hardware fault detection and processing method based on a fault tree

Abstract

The invention discloses an embedded system hardware fault detection and processing method based on a fault tree, which comprises the following steps: step 1, generating a fault tree configuration file; step 2, storing that fault tree configuration file in an embedded system device, reading the fault tree configuration file when the system device is run, and generating a fault detection execution sequence chain list according to the tree structure analysis; step 3, that fault management system periodically traversing and executing the fault detection of each fault unit accord to the order fromthe tail part of the fault detection execution sequence chain list to the head part, and saving the detection result. The hardware fault detection and processing method of the embedded system based onthe fault tree of the invention can flexibly set the hardware to be detected, the detection mode, the fault processing mode and the hierarchical relationship of the hardware by using the fault tree configuration file. The fault of embedded system can be detected in real time, and the fault can be handled in time to prevent the influence from being enlarged.

Description

technical field [0001] The invention relates to an embedded system hardware fault detection and processing method, in particular to a fault tree-based embedded system hardware fault detection and processing method. Background technique [0002] Embedded system refers to a special-purpose computer system that is application-centric, based on computer technology, software and hardware can be tailored, suitable for application systems, and has strict requirements on functions, reliability, cost, volume, power consumption, etc. Embedded systems have the characteristics of small system kernel, strong specialization and compact system. In recent years, embedded system products have been perfected and widely used in various industries around the world. The development and application of embedded system products has become a new national economic growth point for my country's informatization to drive industrialization and industrialization to promote informatization.

Problems solved by technology

When using this method, fault detection is more coupled with system business functions, and adding new hardware fault detection is more complicated; the fault detection of each hardware works independently, there is no unified fault management, and faults between hardware modules, hardware modules and the system Relationship processing is more complicated, which is not conducive to system-level fault management
