Problems solved by technology

The backup method found in the public literature for embedded systems is: increase the backup memory locally, and provide a status flag to determine whether it is necessary to start and restore the system through backup according to the last startup of the system, but the backup used here is stored in Local, and in the event of a hardware failure or replacement, a full recovery of the original running configuration cannot be easily achieved

Embodiment Construction

[0015] The backup and recovery operation method of embedded operating system of the present invention, its steps are:

[0016] (1) According to the switch / jumper setting on the control device, the boot program decides to boot the running system or the simple system;

[0017] (2) When the on-site equipment is installed / debugged, the boot program guides the running system. After the running system starts normally, the debuggers will debug and configure the equipment according to the different needs of users to ensure the normal operation of the equipment;

[0018] (3) During on-site backup operation, the boot program guides the simple system. After the simple system is running, the operator uses a dedicated communication program to communicate with the control device through the network to instruct the backup operation, and the control device backs up the configured embedded operating system through the network. The embedded operating system includes the kernel, file system , ...

Abstract

The invention relates to backup and recovery of operation systems (including application programs and configuration parameters and etc) in universal embedding systems, and submits a specific method of operation system backup/recovery for embedding systems. The invention belongs to application of computer technologies in the field of industrial control techniques. The invention adopts a switch to determine whether a system is running normally, or working in a backup/recovery status. If the system is running normally, an independent operation system is utilized; in backup/recover working status, another simple system is utilized. The backup/recovery operation for the operation system in normal running status is fulfilled through a network.

Description

technical field [0001] The present invention relates to a kind of method of data backup and recovery, specifically the present invention relates to the backup and recovery of operating system (including application program) in a kind of general embedded system, has proposed the concrete method of operating system backup / recovery in embedded system method.
