Embodiment 1

[0059] Such as figure 1 As shown, the present invention provides a storage structure for an industrial computer system, including a memory card and a functional backplane, the memory card is connected to the functional backplane, and the functional backplane is connected to a main function board;

[0060] The functional backplane is used for the communication interface between the main functional board and the memory card to realize data transmission;

[0061] The memory card is used for system storage and data recovery; the memory card adopts a CF card;

[0062] The memory card includes a system boot module 1, a primary and secondary backup logic judgment module 2, a main system module 3 and a secondary system module 4;

[0063] The system boot module 1 is used for booting the system to start;

[0064] The primary and secondary backup logic judging module 2 is used for judging whether to guide the primary system or the backup system when the system boot module 1 guides the ...

Embodiment 2

[0077] Such as figure 2 As shown, the present invention provides a kind of industrial computer system storage method, comprises the following steps:

[0078] S1. Store the main system in the main system module, and store the backup system in the secondary system module;

[0079] S2. The system boot module guides the system to start;

[0080] S3. The primary and secondary backup logic judging module judges whether the main system module is damaged;

[0081] If not, the system boot module guides the system to start from the main system;

[0082] If yes, go to step S4;

[0083] S4. The primary and secondary backup logic judging module judges whether the secondary system module is damaged;

[0084] If not, the system boot module guides the system to start from the secondary system, and at the same time, the primary and secondary system recovery judging module judges whether the backup system is restored to the primary system module; if so, the secondary system module restores...

Abstract

The invention provides a storage structure and a storage method of an industrial control computer system. The structure comprises a memory card and a function backplane, wherein the memory card is connected with the function backplane and the function backplane is connected with a main function board, the function backplane is used for the communication interface between the main function board and the memory card to realize data transmission, the memory card is used for system storage and data recovery, the memory card comprises a system guiding module, a primary and secondary backup logic judging module, a primary system module and a secondary system module; a system boot module, configured to boot the system; a primary and secondary backup logic judging module used for judging whether the primary system or the backup system is booted when the system booting module boots the system; a main system module, which is used for storing the main system and providing guidance to the system boot module; a sub-system module for storing a backup system provided to the system boot module for booting or restoring to the primary system module. The invention adopts the CF memory card to doubleguarantee the startup of the system and the rapid restoration of the system, and the cost is low.

Description

technical field [0001] The invention belongs to the field of industrial computer storage, and in particular relates to an industrial computer system storage structure and method. Background technique [0002] As an indispensable information and command center in industrial production, the industrial computer is constantly updating its functions and performance with the development of electronic components, among which higher requirements are placed on the stability and reliability of the system. If there is a problem with the system and cannot be recovered in time, it will hinder the production of products and cause loss of profits. [0003] At present, most industrial computers use a combination of RAID cards and hard disks to build RAID1 and 5 together to realize system storage and use RAID to recover bad system data. Disadvantages: More components are required: a RAID card and at least 2 hard disks are required to be combined to realize system filling; system recovery: i...
