For example the data bandwidth of FC fiber optic network cards is up to the transmission bandwidth of several Gbps；And PCI is expanded using shared bus convenient for multichannel
It opens up, PCI expansion interfaces all compare more on the backboard of general mainboard, and in the data transmission applications of more low speed, PCI applications are more
Extensively；Multichannel PCI-e interfaces and multichannel pci interface are respectively provided on backboard, the function and the demand of interface for meeting this equipment it
On, moreover it is possible to retain multichannel PCI-e and pci interface, for the Interface Expanding in future；The avionics test system for solving current mainstream is adopted
System is tested to build avionics with the mode of standard and customization avionics test card, occupancy board is more, reusable between test system
Resource is low.Custom Prosthesis board technology involves many areas, and technology reusing degree is poor, causes product maturity poor；If necessary to the portion of changing
Set up meter separately, whole board needs to redesign, and technology flexibility ratio is smaller, is not suitable for improving the problem of being promoted.
Further, massive store passes through the plug-in magnetic disc array cards of PCIe by the way of Raid disk arrays are increased
Carry out dilatation.By the plug-in magnetic disc array cards of PCIE, memory rate can be improved by this method, and storage total capacity can also improve
Very much.
Further, 4TB during massive store.
Compared with prior art, the present invention it has the following advantages and advantages：
1st, multifunctional comprehensive avionics test system of the present invention, by high-speed interface card using PCIE interfaces, such as FC optical fiber
The data bandwidth of network card is up to the transmission bandwidth of several Gbps；And PCI is extended, general master using shared bus convenient for multichannel
PCI expansion interfaces all compare more on the backboard of plate, and in the data transmission applications of more low speed, PCI applications are more extensive；Backboard
On be respectively provided with multichannel PCI-e interfaces and multichannel pci interface, on the function and the demand of interface for meeting this equipment, moreover it is possible to protect
Multichannel PCI-e and pci interface are stayed, for the Interface Expanding in future；Solve current mainstream avionics test system using standard with
The mode of avionics test card is customized to build avionics test system, occupancy board is more, and reusable resource is low between test system.It is fixed
Template card technique processed involves many areas, and technology reusing degree is poor, causes product maturity poor；It is whole if necessary to change part design
Opening board needs to redesign, and technology flexibility ratio is smaller, is not suitable for improving the problem of being promoted；
2nd, multifunctional comprehensive avionics test system of the present invention, by the plug-in magnetic disc array cards of PCIE, can carry by this method
High memory rate, storage total capacity can also improve very much.
