Embodiment Construction

[0016] A method for realizing a multi-redundant computer with flexible scheduling in the present invention includes: an IO interface unit, a network switching board, a monitoring module and several CPU boards, the monitoring module is between the CPU board and the network switching board, Assign and schedule the tasks sent by the network switching board to the CPU board, monitor the working status of the CPU board; when the CPU board fails, switch the task to another CPU board, and reset the CPU board at the same time; the network switching board of the present invention has two There are several CPU boards, and each CPU board is provided with two network ports, and the two network ports are respectively connected to two different network switching boards. The present invention sets the default first network connected to the first network port of the CPU board. The switch board communicates with the outside, and the first network switch board connected to the second network por...

Abstract

The invention relates to a design method of a multi-redundant computer system for flexible dispatching. The method comprises the steps that a monitoring module is involved and arranged between CPU boards and a network switching board, allocates and dispatches tasks sent from the network switching board to the CPU boards and monitors the working state of the CPU boards; when one CPU board breaks down, the tasks are switched to another CPU board; the broken-down CPU board is reset. According to the method of the multi-redundant computer for achieving flexible dispatching, the CPU boards in the system can be flexibly dispatched through the monitoring module, the CPU boards are switched for a breakdown task, and meanwhile the broken-down CPU board is timely reset; the occupation of the CPU boards is reduced, the CPU boards in the system are kept in a normal state at any moment, the reliability of the system tasks is effectively guaranteed, and the redundant number of board cards is reduced; meanwhile, the system structure is simple, goods preparation and maintenance are facilitated, and the system cost is low.

Description

technical field [0001] The invention relates to a design method of a multi-redundant computer system with flexible scheduling. Through flexible scheduling of multiple CPU board resources in the system, the switching of any faulty CPU board is realized, while ensuring the reliability of system tasks, significantly reducing Number of redundant CPU boards. Background technique [0002] In the occasions requiring high reliability, multi-redundant computer systems are mostly used to increase the task reliability of the system. Most of the multi-redundant computer systems currently used in the industry are dual-redundant or triple-two voting systems. Among them, the number of working CPU resources and redundant CPU resources should be configured according to 1:1 or 1:2. The number of redundant resources is large. Due to the fixed replacement relationship, a certain CPU board can only be replaced by its backup board, which is not flexible. . Contents of the invention [0003] ...
