Problems solved by technology

The existing technology provides a status flag to determine whether to start and restore the system through backup according to the last startup of the system by increasing the backup memory, but the backup used here is stored locally, and when the hardware fails or the hardware is replaced It is impossible to easily realize the complete recovery of the original running configuration, and the flexibility is poor
At the same time, manual maintenance is required, which increases maintenance costs, poor security and stability

Abstract

The invention discloses a secure embedded system and an intelligent backup and recovery method thereof. The system comprises a starting management subsystem, a source subsystem, an emergency subsystem and a backup memory. The starting management subsystem comprises two first communication modules and two starting control modules, the two starting control modules are respectively connected with the source subsystem and the emergency subsystem, and the two first communication modules are respectively connected with the source subsystem and the emergency subsystem; the source subsystem is connected with the emergency subsystem, and the source subsystem and the emergency subsystem are both connected with the backup memory. By adopting the secure embedded system and the intelligent backup and recovery method thereof, the backup and recovery of the system can be realized without excessive manual maintenance and hardware cost, the system can be intelligently and automatically backed up in the using process, and can be automatically and intelligently recovered when problems occur, so that the security of the embedded system and the user experience are greatly improved; and the maintenance work of the system is also reduced.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a safe embedded system and an intelligent backup and recovery method thereof. Background technique [0002] Embedded systems usually refer to application-centric, based on embedded computer technology, suitable for special-purpose computer systems that have high requirements for function, reliability, cost, volume, power consumption, etc. Common mobile phones, automobiles, entertainment Systems, etc. all use embedded systems. In the field of industrial control, such as industrial robots, satellites, flight systems, power automation protection and other fields, embedded systems play a pivotal role. [0003] In occasions with stricter requirements, the backup and recovery of embedded systems is also an extremely important function. The existing technology provides a status flag to determine whether to start and restore the system through backup by adding backup memory ac...
