Background technology

Along with development of computer, the anti-adverse environment information terminal has become the nucleus equipment of special trade.As informationalized carrier, special computer is very high to the requirement of information security, and under the environment that civilian computer software and hardware core technology is grasped by foreign country, information processing can't be grasped at present, security can't guarantee especially, so the special computer core technology must domesticize.

The computing machine of current reinforcement generally adopts cpci bus design, though cpci bus is greatly improved than PCI in the reliability that connects, is limited to the restriction of transfer rate, signal that can't transmitting high speed.PCIe is as the bus interface of present main flow, adopt point-to-point mode connected in series, can transmit data at a high speed in high quality, its shortcoming is the same with pci bus, connection reliability be cannot say for sure card, easy obstruction in junction or oxidation under the environment of many dirt, humidity, vibration and loose contact makes computer failure.The CPCIe bus has merged the advantage of cpci bus and PCIe bus, has characteristics such as transfer rate height, reliability height, easy operating and maintenance.

Summary of the invention

Shockproof, the dustproof structural advantage and the transmission performance at a high speed that the purpose of this invention is to provide a kind of CPCIe of utilization bus design a kind of based on homemade processor Godson 3A, not only can satisfy high speed transmission of signals performance, but also a kind of ruggedized computer based on Godson 3A processor that can compatible existing market main flow CPCI integrated circuit board.

The objective of the invention is to realize in the following manner, comprise Godson 3ACPU, north bridge, south bridge, mainboard, multi-functional backboard, the 3UCPCI power supply, power supply backplane, electric board, 3U CPCIe expansion card, compatible 3U expansion card, user's expansion card, external interface, rear panel air plug and 19 in2 U height cabinet are formed, Godson 3ACPU wherein, north bridge, south bridge, multi-functional backboard, the 3UCPCI power supply, power supply backplane, electric board, 3U CPCIe expansion card, compatible 3U expansion card, user's integrated circuit board, external interface is fixed on the mainboard, in mainboard and the multi-functional backboard stuck-at-9 in2 U height cabinet, the multi-functional back of the body, mainboard, 3U CPCIe expansion card, compatible 3U expansion card, power supply backplane, 3UCPCI power supply and external interface are by bus and Godson 3ACPU, north bridge, south bridge connects, electric board is connected with mainboard, user's expansion card 1 is connected with 3U CPCIe expansion card by data line, user's expansion card 2-4 is connected with compatible 3U expansion card by data line, and the rear panel air plug is connected with external interface with the 3UCPCI power supply by data line;

Godson 3ACPU, frequency of operation is 900MHz ~ 1GHz, the CPU power consumption is less than 15W, and mainboard is integrated with each functional module that network, serial ports, USB, VGA, PS2 keyboard and mouse, audio frequency Peripheral Interface are provided and links to each other with mainboard with compatible 3UCPCI expansion card by the 3UCPCIe expansion card;

Backboard adopts the design of 5 groove multifunctions, 1 system's groove, and 4 3U integrated circuit board expansion slot, wherein slot 1 is a standard TYPE I type CPCIe x16 expansion slot; Slot 2 is a TYPE II type CPCIe x1 expansion slot; Slot 3 is the mixed type expansion slot, compatible 3UCPCI expansion card and two kinds of integrated circuit boards of TYPE II type CPCIe x1, and slot 4 is a standard 3U CPCI expansion slot, is convenient to the user and expands the function corresponding interface as required; Power module uses two redundant CPCI power supplys, and the power supply input range is 20-32V.

Excellent effect of the present invention is that this ruggedized computer adopts modular design, and each integrated circuit board links to each other with base plate with the CPCI connector by CPCIe, has significantly reduced the line between integrated circuit board, is convenient to maintenance and guarantee.During maintenance, only need open case front panel wicket replacing malfunctioning module and can deal with problems, need not complicated line etc., shorten the MTTR time greatly, ensure the continuity of system.
