Abstract

The utility model discloses a network data interchanging system, comprising an external network and an internal network, wherein the external network comprises an external network host, and an external network host display 12 and an external network cam which are connected with the external network host, the internal net work comprises an internal network host, and an internal network host display and an internal network cam which are connected with the internal network host, the external network cam aligns to the screen of the internal network host display, the internal network can aligns to the screen of the external network host display, and a connector connected with the external access device is arranged in the external network. Because the internal and the external network cams are used to shoot and acquire the information of the internal and the external network to implement the physical isolation between the internal network and the external network, the system has high security and can make sure of the safety for network interchanging; the cost of the internal and external cams and connection wires for the whole system is far lower than that of the gateway, and under the case of non destroy of the physical isolation safety between the networks, the data interchange between the networks can be implemented in low cost.

Description

The network data switching system

[technical field]

The utility model relates to a kind of computer network data switching system, refers in particular to the data exchange system between external network and the internal network.

[background technology]

We know, in some important departments of government bodies or the unit that some are had relatively high expectations to information privacy, for guarantee information is not stolen, computer is not subjected to outside attack, computer network is divided into internal network and external network, between internal network and external network, do not allow the connection of physical medium, therefore when external network need be visited information in the internal network, common solution is to use gateway to carry out message transmission between the physical isolation network, but, the price of gateway is very high, and the cost that causes network security to be used improves.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can guarantee network exchange safety, under the physical isolation fail safe that does not destroy between the network, can realize the system of exchanges data between the network again with lower cost.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of network data switching system, it includes external network and internal network, described external network includes outer net main frame, the outer net host display 12 that is connected with the outer net main frame and outer net camera, intranet host display and Intranet camera that internal network includes intranet host, is connected with intranet host, the screen of the alignment lens intranet host display of described outer net camera, the screen of the alignment lens outer net host display of described Intranet camera is provided with the connector that is connected with external reference equipment in described external network.

In the improvement project to above-mentioned network data switching system, the connector that is connected between described external network and external reference equipment is wireless or line structure is arranged.

In the improvement project to above-mentioned network data switching system, described connector is the outer net interchanger.

Compared with prior art, the beneficial effects of the utility model are: owing to be that the information of utilizing inside and outside net camera to take, gather inside and outside network respectively realizes physically-isolated between inside and outside the network, so security performance height of the present utility model can be guaranteed the safety of network exchange; And the expense of used inside and outside net camera of whole system and connecting line is well below gateway, so system under the physical isolation safety conditions of not destroying between the network, can realize exchanges data between the network with lower cost again.

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

[description of drawings]

Fig. 1 is the line schematic diagram of the utility model embodiment;

Fig. 2 is the block diagram of the utility model embodiment.

[embodiment]

The utility model is a kind of network data switching system, it includes external network 1 and internal network 2, described external network 1 includes outer net main frame 11, outer net host display 12 that is connected with outer net main frame 11 and outer net camera 13, internal network includes intranet host 21, intranet host display 22 that is connected with intranet host 21 and Intranet camera 23, described outer net camera 13 is connected with intranet host 21 and the screen of its alignment lens outer net host display 12, described Intranet camera 23 is connected with outer net main frame 11 and the screen of its alignment lens intranet host display 22, is provided with the connector that is connected with external reference equipment 3 in described external network 1.Like this when external reference equipment will be visited inner-mesh network 2, its access request is presented on the screen of outer net host display 12 after by outer net main frame 11 encoding process, and deliver on the intranet host 21 after being collected by the camera lens of outer net camera 13, whether legal by intranet host 21 decision request, after determining to be legitimate request, the information coding that 3 requests of external reference equipment are required is shown on the intranet host display 22; Be sent on the outer net main frame 11 after collecting by the camera lens of Intranet camera 23 again, read by external reference equipment 3 at last, realize the process of external equipment dereference internal network by outer net main frame 11 decoded information; After visitor's request is by outside camera collection, be sent to internal network but when being identified as illegal request, internal network can the information that access request is required not be presented on its display by compiled code, so illegal request just can't obtain required information.The utility model is that the information of utilizing inside and outside net camera to take, gather inside and outside network respectively realizes physically-isolated between inside and outside the network, so security performance height of the present utility model can be guaranteed the safety of network exchange; And the expense of used inside and outside

net camera

23,13 of whole system and connection cable is well below gateway, so system under the physical isolation safety conditions of not destroying between the network, can realize exchanges data between the network with lower cost again,

The connector that is connected between described external network 1 and external reference equipment 3 can be wireless (as a wireless receiving-transmitting device) or line structure is arranged.Under normal conditions, because external network 1 has a lot of covers, will connect with outer net interchanger 14 between them, what at this moment the outer net interchanger also can play connector is used for connecting external network 1 and external reference equipment 3.Outer net interchanger 14 can be wireless or line structure is arranged.

In like manner, internal network 2 also can have a lot of covers, also connects with Intranet interchanger 24 between them.Intranet interchanger 24 also can be wireless or line structure is arranged.
