Abstract

The utility model discloses an EPIC single board computer. The computer adopts the embedded design to arrange an onboard memory on a PCB board, thereby avoiding the poor contact of the EPIC single board computer memory due to vibrations or other reasons during the industrial automation control application process under harsh environments.

Description

A kind of EPIC single board computer

Technical field

The utility model relates to computer technology, particularly a kind of EPIC single board computer technology.

Background technology

Development and network application continuous advancement in technology along with industrial control technology, Industrial Control Computer constantly develops to microminiaturized, decentralized, personalized, customizations direction, and the Industrial Control Computer system also develops towards networking, synthesization, intelligentized direction.Along with the progress of using IT to propel industrialization, which will, in turn, stimulate IT application, the market of Industrial Control Computer is in continuous expansion.Simultaneously, market for the demand of industrial computer EPIC single board computer product in continuous increase, also more and more higher to its performance requirement.

Yet, present existing EPIC single board computer generally all adopts internal memory outside plug type or plate to paste the 128MB internal memory, in the comparatively abominable industrial automation control application process of environment, owing to vibration or otherwise reason, the situation of EPIC single board computer internal memory loose contact very easily takes place, thereby the stability decreases that causes whole industrial control system easily, and a large amount of field datas more requires computing machine to have remarkable processing power, plate to carry the obviously not enough domination of internal memory of 128MB.Existing EPIC single board computer product can't well satisfy requirements of different users.

Therefore, how to make the EPIC single board computer have shockproof function, improve stability, thereby avoid the internal memory loose contact and cause the unsettled phenomenon of system works to take place, can satisfy simultaneously the demand of user again to big internal memory, the elevator system performance makes product have more the market competitiveness, becomes problem anxious to be solved.

The utility model content

The purpose of this utility model provides a kind of EPIC single board computer, has shockproof function, can avoid the internal memory loose contact and causes the unsettled phenomenon of system works to take place, and can satisfy the demand of user to big internal memory, elevator system performance simultaneously again.

For solving technical matters of the present utility model, the utility model discloses a kind of EPIC single board computer, comprises chipset, CPU socket, interface and bus, wherein, on pcb board, adopts embedded design that the internal memory that plate carries is set.

More excellent, save as internal memory in described smaller or equal to 512MB.

More excellent, the internal memory that described plate carries is positioned at a side of BIOS and South Bridge chip.

Compared with prior art, the utlity model has following beneficial effect:

The utility model adopts embedded design, at pcb board the internal memory that plate carries is set, thereby can avoid in the comparatively abominable industrial automation control application process of environment,, the situation of EPIC single board computer internal memory loose contact taking place owing to vibration or otherwise reason.

Specific embodiment

Below in conjunction with Figure of description EPIC single board computer of the present utility model is described in detail.

Please refer to Fig. 1 and Fig. 2, Fig. 1 is the topology layout figure of a kind of EPIC single board computer of the utility model embodiment, and this EPIC single board computer can comprise with lower interface.

Fig. 2 is the circuit structure block diagram of a kind of EPIC single board computer of the utility model embodiment, the circuit of this EPIC single board computer can comprise the CPU21 of series connection successively, north bridge 22, south bridge 23, IO chip 24, according to demand, this EPIC single board computer can also comprise cpu power chip 211, clock chip 212, VGA display 221, LVDS display 222, plate carry 512 internal memories 223, IDE﹠amp; 231,4 USB2.0 interfaces 232 of CF interface, PC104Plus interface 233, Dian Yuanguanli ﹠amp; Reset 234,235,2 network adapter 236 of voice adapter, BIOS241,4 serial interfaces 242, printer interface 243, GPIO interface 244, Jian Pan ﹠amp; Mouse interface 245, house dog interface 246.

Wherein, CPU21 all with cpu power chip 211, clock chip 212 links to each other; North bridge 22 all with VGA display 221, LVDS display 222, plate carry 512 internal memories 223 and link to each other; South bridge 23 equal and IDE﹠amp; 231,4 USB2.0 interfaces 232 of CF interface, PC104Plus interface 233, Dian Yuanguanli ﹠amp; Reset 234,235,2 network adapter of voice adapter 236 link to each other; IO chip 24 equal and BIOS241,4 serial interfaces 242, printer interface 243, GPIO interface 244, Jian Pan ﹠amp; Mouse interface 245, house dog interface 246 links to each other.

The disclosed a kind of EPIC single board computer of the utility model embodiment can adopt the X86 framework, comprises that chipset, CPU socket CN1, plate carry internal memory, interface and bus.

Chipset comprises north bridge chips CN2, South Bridge chip CN3 and BIOS chip.Wherein, the position of north bridge chips CN2 on mainboard is nearest apart from CPU, the closest with communicating by letter between the CPU, be responsible for CPU get in touch and control internal memory, AGP data in north bridge 22 internal transmission, provide the type of CPU and dominant frequency, the front-side bus frequency of system, the type (SDRAM of internal memory, DDR SDRAM and RDRAM etc.) and supports such as max cap., the error correction of AGP slot, north bridge chips CN2 links to each other with CRT, LVDS222, integrated displaing core.South Bridge chip CN3 is positioned on the mainboard from CPU socket CN1 below far away, mainly is responsible for the data processing and the transmission of external unit.Be used for linking to each other with I/O equipment, and be in charge of interruption, it is more smooth and easy to allow equipment work get, and it provides the support to keyboard controller, real-time clock controller, USB USB (universal serial bus) etc.The BIOS Basic Input or Output System (BIOS) is one group and is cured in the computer, the lowermost level program of direct hardware controls is provided, it is the hinge that is communicated with between software program and the hardware device, the instant requirement of being responsible for solving hardware, and by the operation requirement specifically execution of software to hardware.At first call some hardware informations here from during system start-up, its performance directly affects the compatibility of system software and hardware.BIOS supports the erasable Flash Rom user of 4M can conveniently upgrade, support PNP, supports anti-virus functionality, supports greater than the 160G big capacity hard disk in the utility model.
