Problems solved by technology

[0002] When the embedded system is under high temperature, high humidity, unstable power supply, insufficient voltage load capacity or insufficient battery power, the system will be repeatedly powered on and off to restart, and the internal parameters of the system may be lost during the restart process, causing the system to return. To the factory settings or even the data is completely lost, so that the system cannot be started normally, and in order to solve such problems, an embedded system parameter backup method that can protect the system data security is needed

Embodiment Construction

[0018] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] refer to figure 1 as well as figure 2 , propose an embodiment of the embedded system parameter backup method of the present invention:

[0020] A method for backing up parameters of an embedded system. The configurable system parameters required by the system for power-off storage and power-on recovery are stored in a structure, and the structure also includes two parameters: the data length of the structure and the data inspection value; the backup Methods as below:

[0021] The institutions that store the configurable system parameters required by the system for power-down saving and power-on recovery are respectively stored on two different sectors on the disk. In this embodiment, these two sectors are called sector A Area and sector B, where system parameter data is stored in sector A, and system parame...

Abstract

The invention discloses an embedded system parameter backup method. The system parameter data and the system parameter backup data which store the configurable system parameters of power-down storage and power-on recovery required by a system are respectively arranged on two different sectors of a disk, so that it can be ensured that at least one of the two data is correct when the two data are erased, and the system can be normally started and run. During the system operation process, when the system parameters change, the system backup parameters are erased and updated on the premise of ensuring that the system parameter data is correct, so that the security of the data can be effectively kept in the repeated restarting process of the system, and the system data are prevented from being mistaken or lost.

Description

technical field [0001] The invention relates to the field of embedded systems, in particular to an embedded system parameter backup method. Background technique [0002] When the embedded system is under high temperature, high humidity, unstable power supply, insufficient voltage load capacity or insufficient battery power, the system will be repeatedly powered on and off to restart, and the internal parameters of the system may be lost during the restart process, causing the system to return. To the factory settings or even complete data loss, the system cannot be started normally, and in order to solve such problems, an embedded system parameter backup method that can protect system data security is needed. Contents of the invention [0003] The main purpose of the present invention is to provide an embedded system parameter backup method capable of protecting system data security. [0004] The present invention proposes a method for backing up embedded system parameter...
