Embodiment Construction

[0032] The technical solution of the present invention will be described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the method for redundant backup and automatic recovery of important parameters of the present invention is realized by using storage backup technology and mutual backup technology.

[0034] According to a preferred embodiment of the present invention, the method for redundant backup and automatic recovery of important parameters further includes: storing important parameters in multiple areas of the non-volatile storage space in a mutual backup manner, and reading the stored parameters when recovery is required. The important parameters stored.

[0035] Preferably, storing important parameters in multiple areas of the non-volatile storage space in a mutually backup manner includes: dividing the non-volatile storage space into multiple equally divided areas, and storing a copy of important parameters in each area.

Abstract

In order to solve the problem of reliable storage of these important parameters and the problem of automatic parameter recovery after a single machine failure, the present invention provides a redundant backup and automatic recovery method of important parameters, which is realized by using storage backup technology and mutual backup technology. This method adopts the two-out-of-three backup technology of important parameter storage space and the mutual backup technology of master and slave machines for important parameters, which solves the problem of reliable storage of important parameters and the problem of automatic recovery of parameters after a single machine fails.

Description

technical field [0001] The invention relates to the technical field of computer control, more specifically, to a method for redundant backup and automatic recovery of important parameters. Background technique [0002] In order to improve the adaptability of the product to the system and environment, it is necessary to modify important parameters such as process parameters and device initial values ​​through the external CAN bus interface, serial port, etc.; at the same time, relevant parameters need to be saved after power-off. [0003] Important parameters such as process parameters and initial values ​​of equipment play a vital role in the process control of the system. If the relevant parameters are wrong, it will lead to process control failure at least, and task failure at worst. Contents of the invention [0004] In order to solve the problem of reliable storage of these important parameters and the problem of automatic parameter recovery after a single machine fai...
