Terminal access equipment fault recovery system based on linux kernel

Abstract

The invention provides a terminal access equipment fault recovery system based on a linux kernel, and belongs to the field of safety monitoring. In order to solve the problem that a system needs to bechanged if abnormality occurs in the system upgrading process of terminal access equipment at present; risks are caused; and the efficiency is low. The present invention comprises: a main body; before a kernel or root file system is upgraded and updated; marking a kernel or a root file system; when the equipment upgrades the kernel or the root file system through the UI interactive interface, updating the kernel or the root file system; the bootstrap program detects whether the mark of the kernel or the root file system exists or not in real time, if yes, the bootstrap program can detect thatthe mark of the kernel or the root file system exists, it shows that upgrading of the kernel or the root file system is not completed, at the moment, the backup kernel can be automatically copied tothe kernel. The system is recovered; and after the kernel or root file system is upgraded by the equipment through the UI interactive interface, if the system cannot work normally, the system is actively recovered through the key, i.e., the key enters a recovery mode and is recovered from the backup system respectively.

Description

technical field [0001] The invention relates to safety monitoring technology, in particular to a system for recovering failure of terminal access equipment based on linux kernel. Background technique [0002] At present, small and micro servers, gateway equipment, and various terminal access equipment widely exist in various industries and families. [0003] For the devices mentioned above, various system abnormalities will inevitably occur during system operation, such as system problems caused by software compatibility, problems caused by version upgrades, system problems caused by accidental deletion of files, and problems caused by power outages during the upgrade process Wait. The basic system factory reset function provided by general equipment is mainly used to solve system problems caused by software compatibility and configuration. During the upgrade process, it is usually prompted not to disconnect the power supply or to keep the battery fully charged. [0004] ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a terminal access device failure recovery system based on the linux kernel, so as to solve the problem that the system needs to be changed if an abnormality occurs during the upgrade process of the current terminal access device system, which will bring risks and inefficiency.
