Abstract

The invention relates to a CPCI redundancy backup system and comprises at least a redundancy backup unit which comprises a first system board module, a second system board module and one or two sections of CPCI bus; wherein, a section of CPCI bus only can be provided with CPCI bus control management by the first system board module or the second system board module at any moment; when the first system board module carries out the CPCI bus control management, the second system board module can receive backup data sent by the first system board module, and when the first system board module breaks down, the second system board module switches the CPCI bus control management authority. The CPCI redundancy backup system can provide the redundancy backup to all plug-ins including a primary system board; a broken-down board can be isolated automatically; and a backup component can be connected automatically. The CPCI redundancy backup system has high reliability and best price performance ratio and is particularly fit for high reliable communication and industry control platform with large I/O data volume, and the CPCI redundancy backup system has wide application prospect in the fields of modern communication, spaceflight, military matters, etc.

Description

technical field [0001] The invention relates to a redundant backup system, more specifically, to a CPCI redundant backup system. Background technique [0002] The CompactPCI (CPCI) bus is a bus specification developed by the Industrial Computer Manufacturers Organization in 1994. The CPCI bus is a high-performance industrial PCI bus based on the PCI bus standard of desktop computers. At the same time, it adopts the very popular Ocard format like the VME bus, so that the CPCI bus standard fully integrates the current two major buses (PCI bus and VME bus) standard advantages: it not only inherits the high performance and high bandwidth of the PCI bus, but also retains the Eurocard-type reinforced package of the VME bus. Due to the use of European-style cards, compared with the standard desktop PCI bus, the number of slots supported by the CPCI bus is twice that of the standard PCI system, up to 8 slots, and can also be expanded through the PCI bridge, making The number of sl...
