Abstract

The utility model discloses a security isolation desktop computer which comprises at least two main boards and a KVM board. The two main boards are arranged in two different host cases, the two host cases are connected with a base, and the KVM board is arranged in the base; the output ends of the two main boards are respectively connected with the input end of the KVM board, the main boards are provided with independent output interfaces, and the independent output interfaces are arranged on the host cases. According to the security isolation desktop computer, internal and external network security isolation on at least two main boards is achieved through the KVM board, the two main boards also can be used as independent cases to be used independently, and the security isolation desktop computer is suitable for working fields that one host is private and only can be connected with an Internal network and Internet connection is needed.

Description

A kind of safety isolation desktop computer

Technical field

The utility model relates to a kind of computer, relates in particular to a kind of safety isolation desktop computer.

Background technology

Intranet and extranet isolation is carried out physical isolation by the network of the different security levels such as classified network and Office Network, in-house network and internet in simple terms exactly, to prevent the leakage of information and the system problem causing due to external attack.The proposition of " two net isolation " is in order to meet the privacy requirements of the relevant departments that relate to secret information.National Administration for the Protection of State Secrets plays the 6th of the < < Regulations of Internet Security of Computer Information System > > chapter 2 security system of enforcement and just clearly stipulates on January 1st, 2000: " computer information system that relates to state secret; must not be connected with Internet or other public information networks directly or indirectly must be carried out physical isolation.

Traditional method that realizes inside and outside network physical isolation is: same user is equipped with two computing machines, connects respectively internal network and external network.Although this method has realized the complete physical isolation between intranet and extranet, but take up room, obviously increase, adopt hard disc physical isolating means owing to having used same set of central processing unit and internal memory, when system is switched, need to spend the regular hour reinitializes internal memory and loads necessary program, when needs frequently switch intranet and extranet, affect work efficiency.

Utility model content

The purpose of this utility model provides a kind of simple in structure with regard to being in order to address the above problem, switch fast the safety isolation desktop computer of intranet and extranet.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The utility model comprises at least two mainboards and KVM plate, two described mainboards are arranged in two different mainframe boxes, two described mainframe boxes are connected with base respectively, in described base, be provided with described KVM plate, the output terminal of two described mainboards is connected with the input end of described KVM plate respectively, described mainboard is provided with independent output interface, and described independent output interface is arranged on described mainframe box.

Particularly, described independent output interface comprises USB interface, HDMI interface, DVI/VGA interface, network interface and power supply interface.

Further, on described base, be provided with the VGA video input interface corresponding with described mainboard, data transmission interface, base USB interface and shared VGA video output interface.

Particularly, between described two mainframe boxes, by aluminium sheet, isolate.

Further, on described base, be provided with louvre.

The beneficial effects of the utility model are:

The utility model is arranged on separately independently mainframe box by the realization of KVM plate at least two mainboards and realizes isolating safely of intranet and extranet, in addition two mainboards also can be separately used separately as cabinet independently, be applicable to wherein have one to maintain secrecy and can only connect internal network, have again the work-yard that needs connecting Internet demand.

Fig. 1 is front view of the present utility model;

Fig. 2 is rear view of the present utility model.

Fig. 3 is described understructure schematic diagram of the present utility model..

Fig. 4 is perspective view of the present utility model.

In figure: 1-base, 2-VGA video input interface, 3-data transmission interface, 4-louvre, 5-VGA video output interface, 7-network interface, 6-aluminium sheet, 8-mainframe box, 9-base USB interface, 10-DVI/VGA interface, 11-HDMI interface, 12-power supply interface, 13-USB interface.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in figs. 1 and 4, the utility model comprises at least two mainboards and KVM plate, two mainboards are arranged in two different mainframe boxes 8, two mainframe boxes 8 are connected with base 1 respectively, are provided with KVM plate in base 1, and the output terminal of two mainboards is connected with the input end of KVM plate respectively, thereby the mainboard independent operating that can guarantee, do not interfere with each other in the course of the work, mainboard is provided with independent output interface, and independent output interface is arranged on mainframe box 8.

As shown in figs. 1 and 4, independent output interface comprises usb 13, HDMI interface 11, DVI/VGA interface 10, network interface 7 and power supply interface 12.

As shown in Figure 3, on base 1, being provided with the VGA video input interface 2 corresponding with mainboard, data transmission interface 3, base USB interface 9 and shared VGA video output connects, 5, VGA video output interface 5 is the general-purpose interface of liquid crystal display or existing television indicator, and the office equipment such as base USB interface 9 can external access of mouse, keyboard, display and scanner, printing device is realized file-sharing by KVM plate.

As illustrated in fig. 1 and 2, between two mainframe boxes, by aluminium sheet 6, isolate, due to the good heat conductivity of aluminium sheet 6, thereby the mainboard that can guarantee can dispel the heat in time, is provided with louvre 4 on base 1, improves the thermal diffusivity of mainboard.

In the present embodiment, on base, be provided with two independent mainboards, after electric power starting, two main board system self checks start successfully, and KVM plate acquiescence enters a certain predetermined mainboard, and the software systems of mainboard start complete, enter operating system, the display interface that shows this predetermined mainboard by external display device, the signal of mouse, keyboard is connected to this predetermined mainboard by base USB interface 9, and controls the work that it connects mainboard.In the time will switching to other mainboards, only need input corresponding order by keyboard, as " ALT+1 " represents to be switched to the first mainboard, " ALT+2 " represent to be switched to the second mainboard, these orders are all default, mainboard can these orders of initiative recognition, and after receiving orders, be switched to corresponding mainboard, be switched to after corresponding mainboard, display device shows the interface content of current mainboard, the peripherals such as each input media also change by KVM plate the mainboard that is connected to switching simultaneously, when needs are used separately, external equipment can be connected with the independent output interface of each mainboard, independent use.

These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
