Redundant system based on heterogeneous diversity

Abstract

The invention discloses a redundant system based on heterogeneous diversity, and the system comprises a host cage, an extension cage, a plurality of clamping pieces and information transmission equipment. The host cage and the extension cage are internally provided with a plurality of slots, each clamping piece is configured in the corresponding slot, and the information transmission equipment isconnected with each clamping piece in the host cage and the extension cage, so that information interaction among the clamping pieces can be realized. By applying the technical scheme, the informationin each clamping piece configured in the slots can be directly gathered to the information transmission equipment, and information interaction of all the clamping pieces is carried out in the information transmission equipment, so that the slots where the clamping pieces are positioned do not need to be adjacent, and the clamping pieces do not need to be configured in the same cage; requirementsof redundant clamping pieces in different physical spaces are met, common cause failure is avoided, and the reliability of the system is improved.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to a redundant system based on heterogeneous diversity. Background technique [0002] The redundant technology of the control system generally adopts two or more sets of identical and relatively independent configuration designs to improve the availability of the entire control system and reduce unplanned shutdowns caused by random failures of the control system, which in turn lead to production suspension, cause loss. [0003] The existing dual redundancy and triple redundancy are physical slots adjacent to each other. Redundancy and information exchange are realized through the physical link between the two / three slots. Once the previous design is completed, the redundant The relative positions of the remaining clips are fixed, that is, only the specified two / three clips can be mutually redundant, and these two / three clips are all configured in the same cage, ...

[0002] The redundant technology of the control system generally adopts two or more sets of identical and relatively independent configuration designs to improve the availability of the entire control system and reduce unplanned shutdowns caused by random failures of the control system, which in turn lead to production suspension, cause loss

[0003] The existing dual redundancy and triple redundancy are physical slots adjacent to each other. Redundancy and information exchange are realized through the physical link between the two / three slots. Once the previous design is completed, the redundant The relative positions of the remaining clips are fixed, that is, only the specified two / three clips can be mutually redundant, and these two / three clips are all configured in the same cage, which cannot meet the requirement of redundancy. Requirements for other card parts in different physical spaces may lead to common cause failure, and the reliability of the system is very low
