Description

Device for avionics collecting test

Technical field

The utility model is related to avionics tests, and in particular to be used for the device of avionics collecting test.

Background technology

The huge number of avionics bus, communication protocol become increasingly complex.The same Aerial Electronic Equipment usually contains a variety of avionics Interface, standard and nonstandard interface are simultaneously deposited, and to avionics test system, more stringent requirements are proposed.The avionics of mainstream tests system at present Avionics is built by the way of standard and customization avionics test card and tests system, and occupancy board is more, can be weighed between test system It is low with resource.Custom Prosthesis board technology involves many areas, and technology reusing degree is poor, causes product maturity poor.If necessary to change Part is designed, and whole board needs to redesign, and technology flexibility ratio is smaller, is not suitable for improving being promoted.

Utility model content

The device for avionics collecting test is provided, multifunctional comprehensive avionics tests system can be to 1553,429 and FC etc. Avionics bus is acquired, monitors and tests, and the present apparatus remains multichannel extended channel, can be used in other work(of extending user It can demand.

The utility model is achieved through the following technical solutions：

I7-CPUx86 mainboards on the device of avionics collecting test, including PICMG backboards and PICMG backboards, Pci expansion slot, PCI function cards, PCIe function cards, massive store；PCIE interfaces are used for the high-speed interface of FC fiber optic network cards； PCI uses shared bus, is extended for multichannel.To solve the problems, such as in background technology, PCIE interfaces are used by high-speed interface card, For example the data bandwidth of FC fiber optic network cards is up to the transmission bandwidth of several Gbps；And PCI uses shared bus, expands 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 all had on backboard, the function and interface that meet this equipment demand it On, moreover it is possible to retain multichannel PCI-e and pci interface, is used 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 increasing Raid disk arrays 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 when massive store.

The utility model compared with prior art, has the following advantages and advantages：

1, the utility model is used for the device of avionics collecting test, and PCIE interfaces, such as FC are used by high-speed interface card The data bandwidth of fiber optic network card is up to the transmission bandwidth of several Gbps；And PCI uses shared bus, is extended convenient for multichannel, one As mainboard backboard on PCI expansion interfaces all compare it is more, in the data transmission applications of more low speed, PCI applications are more extensive； Multichannel PCI-e interfaces and multichannel pci interface are all had on backboard, on the demand of the function and interface that meet this equipment, also Multichannel PCI-e and pci interface can be retained, be used for the Interface Expanding in future；The avionics test system of current mainstream is solved using mark The accurate mode with customization avionics test card tests system to build avionics, and occupancy board is more, reusable resource between test system It is low.Custom Prosthesis board technology involves many areas, and technology reusing degree is poor, causes product maturity poor；It is set if necessary to change part Meter, whole board need to redesign, and technology flexibility ratio is smaller, are not suitable for improving the problem of being promoted；

2, the utility model by this method may be used for the device of avionics collecting test by the plug-in magnetic disc array cards of PCIE To improve memory rate, storage total capacity can also improve very much.
