Abstract
The invention relates to a network monitoring system, in particular to an internal/external network controller. The internal/external network controller comprises a personal computer (PC) interface, a network line interface, a switch array module connected in series between the PC interface and the network line interface, a singlechip for detecting whether networks the PC interface and the network line interface access are the same and controlling the switch array module to be conducted, and a display module for indicating the type of the network the PC interface or the network line interface accesses, wherein the display module is connected with the singlechip. The internal/external controller has the advantages that the problem of hybrid connection of an internal network and an external network, caused by mis-insertion and mis-connection in use, is solved by adopting a physical on/off mode; and leakage of internal data caused by hybrid connection of the internal network and the external network is avoided.
Description
Technical field
The present invention relates to network monitoring system, be specifically related to a kind of internal-external network controller.
Background technology
Along with the development of network, general existence of phenomenon of local area network (LAN) and the coexistence of internet dual network, and being gradually improved of information management requires internal-external network strictly to isolate.Although each system is to the strict regulation of having access to of intranet and extranet and severe examination, but still have part unit and the employee illegal external connection that still happens occasionally, when entity and individual at different levels are examined by higher level department, the unit of causing ranks behind to target in system's same trade, and the same trade of the unit of seriously influencing is to the mark rank.More seriously the illegal external connection attack that might make our Intranet be subject to hacker, virus causes leaking of each application system paralysis in the Intranet and enterprise's sensitive information.
The reason major part that illegal external connection occurs is to cause owing to mispluging the misconnection netting twine, what existing Desktop Monitoring software was realized is subsequent supervision, can not realize physical isolation during for the generation illegal external connection, although each system has formulated many rules and regulations, way of rewards and punishments, each system is at the control software that uses desktop terminal, but illegal external connection still happens occasionally, and mends the fold after the sheep is lost after all, because intranet and extranet link.
Summary of the invention
The invention provides a kind of internal-external network controller, solved intranet and extranet in use misplug misconnection and the problem that causes the data of Intranet to leak.
For solving above-mentioned technical problem, the present invention by the following technical solutions: a kind of internal-external network controller comprises:
A PC interface;
A cable interface;
A switch arrays module is series between PC interface and the cable interface;
Whether the network of detection PC interface and cable interface access belongs to consolidated network, and the control switch array module single-chip microcomputer of path whether;
A display module that is used for the network type of prompting PC interface or cable interface access, display module links to each other with single-chip microcomputer.
For making the present invention play better technique effect, further technical scheme is that above-mentioned single-chip microcomputer is connected with to link to each other with outside civil power the power management module of power supply is provided.
Compared with prior art, the invention has the beneficial effects as follows: internal-external network controller of the present invention is connected between PC and the netting twine, detect PC and belong to internal lan or the PC of external the Internet, and the detection netting twine belongs to internal lan or the netting twine of external the Internet, judge pairing by single-chip microcomputer again, determine whether to be communicated with PC and netting twine, avoided the problem that misconnection causes the intranet and extranet hybrid junction that misplugs in the use procedure by the mode break-make of physics like this, guaranteed that internal data can not leak because of the intranet and extranet hybrid junction.

Fig. 2 is the connection block diagram of embodiment of internal-external network controller of the present invention when connecting PC.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 and Fig. 2 show an embodiment of internal-external network controller of the present invention: a kind of internal-external network controller comprises:
A PC interface;
A cable interface;
A switch arrays module is series between PC interface and the cable interface;
Whether the network of detection PC interface and cable interface access belongs to consolidated network, and the control switch array module single-chip microcomputer of path whether;
A display module that is used for the network type of prompting PC interface or cable interface access, display module links to each other with single-chip microcomputer.
Another embodiment of internal-external network controller according to the present invention, single-chip microcomputer are connected with to link to each other with outside civil power provides the power management module of power supply.
Its operation principle is: when the cable interface connected with network cable of this internal-external network controller, detect and judge that the network type that this netting twine connects belongs to local area network (LAN) or internet, and in the corresponding prompting of display module demonstration, such as lamp or the Word message prompting of different colours; When the PC interface of this internal-external network controller connects PC, detect the data of judging this PC and belong to local area network (LAN) or internet, and show corresponding prompting at display module.
PC also belongs to local area network (LAN) if the netting twine that detects belongs to local area network (LAN), and then Single-chip Controlling switch arrays path is communicated with netting twine and PC.
PC also belongs to the internet if the netting twine that detects belongs to the internet, and then Single-chip Controlling switch arrays path is communicated with netting twine and PC.
PC belongs to the internet if the netting twine that detects belongs to local area network (LAN), and then the Single-chip Controlling switch arrays open circuit, and netting twine and PC can not be communicated with.
PC belongs to local area network (LAN) if the netting twine that detects belongs to the internet, and then the Single-chip Controlling switch arrays open circuit, and netting twine and PC can not be communicated with.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", " preferred embodiment " etc., the specific features, structure or the characteristics that refer in conjunction with this embodiment description are included among at least one embodiment of the application's generality description.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also fall within the scope of the invention.
Although invention has been described with reference to a plurality of explanatory embodiment of the present invention here, but, should be appreciated that those skilled in the art can design a lot of other modification and execution modes, these are revised and execution mode will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes also will be obvious.
