Description
Technical field
The present invention relates to power communication security fields, be specifically related to Intranet computer and prevent outreaching short-message control device.
Background technology
Electric system is as labour-intensive and that technology gold content is high enterprise, and technology innovation is very fast, just has security requirements accordingly to enterprise.The internal network that electric system has oneself, transmits file and mainly contains two approach: one is transmitted by company Intranet mailbox; Two is by intranet host USB interface, and insertion USB flash disk copied files or data carry out file transfers, but uses nonbusiness's special-purpose USB flash disk easily to cause classified document or confidential data to leak.Host computer USB interface is except inserting with USB flash disk, insert keyboard, insert except mouse, and can also be mobile phone charging by USB interface, namely Intranet outreaches mobile phone, so just easily causes classified document or confidential data to leak, and causes loss in various degree to enterprise.
At present, electric system does not still have special equipment to prevent this type of problem of divulging a secret.Therefore, in the urgent need to the enforceable USB control device of one, prevent Intranet computer from causing the generation of enterprise's secret leakage accident by equipment such as USB interface illegal external connection mobile phone and USB flash disks.
Summary of the invention
For the problems referred to above, the invention provides one and be applied to Intranet computer, USB interface can be prevented in violation of rules and regulations external and then prevent the novel short-message control device of information-leakage.
Object of the present invention realizes by the following technical solutions:
Intranet computer is anti-outreaches short-message control device, comprises USB mainboard connector, relay, Logic control module, gsm module, stabilized voltage supply and hub; Described USB mainboard connector, relay are connected successively with hub, and hub is connected respectively with multiple USB interface; Described Logic control module is connected with relay with gsm module respectively, and described stabilized voltage supply respectively andlogic control module is connected with gsm module.
Preferably, described relay is direct current 12 volts of relays.
Preferably, described stabilized voltage supply is direct current 12 volts of stabilized voltage supplys.
Preferably, described USB mainboard connector is connected with computer main board.
Preferably, described gsm module receives the password short message instruction being switched on or switched off USB interface that mobile phone sends.
Preferably, described hub is four mouthfuls of hubs, and described USB interface has 4, and four mouthfuls of hubs are connected with 4 USB interface respectively.
Beneficial effect of the present invention is: utilize the means such as gsm module, Logic control module and relay the USB interface of cell phone password short-message verification and computer to be combined, password correctly then performs the instruction being switched on or switched off USB interface, code error does not then perform the instruction being switched on or switched off USB interface, even if can not divulge a secret or illegal external connection when inserting USB flash disk or mobile phone so yet.Only have the cell phone password short-message verification bound with computer correct, just remote control can be switched on or switched off USB interface, efficiently avoid Intranet computer to divulge a secret or illegal external connection, all computers of each transformer station of national grid and office space can be widely used in, also can wide popularization and application in the unit that other have a security requirements, and it is simple and practical, stable and reliable for performance.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to the following drawings.
Fig. 1 is structural representation of the present invention.
Reference numeral: USB mainboard connector-1; Hub-2; Relay-3; Gsm module-4; Logic control module-5; Stabilized voltage supply-6; USB interface-7.
Embodiment
The invention will be further described with the following Examples.
Intranet computer is as shown in Figure 1 anti-outreaches short-message control device, comprises USB mainboard connector 1, relay 3, Logic control module 5, gsm module 4, stabilized voltage supply 6 and hub 2.
USB mainboard connector 1, relay 3 are connected successively with hub 2, hub 2 is connected with multiple USB interface 7, and hub 2 is four mouthfuls of hubs in this embodiment, and USB interface 7 has 4, four mouthfuls of hubs are connected with 4 USB interface 7 respectively, and USB mainboard connector 1 is connected with computer main board.
Logic control module 5 is connected with relay 3 with gsm module 4 respectively, stabilized voltage supply 6 respectively andlogic control module 5 is connected with gsm module 4, relay 3 is direct current 12 volts of relays, stabilized voltage supply 6 is direct current 12 volts of stabilized voltage supplys, and stabilized voltage supply 6 is for powering to gsm module 4 and Logic control module 5.Gsm module 4 receives the password short message instruction being switched on or switched off USB interface 7 that mobile phone sends, and this gsm module 4 needs possess conventional SMS, comparatively economical and practical, can certainly use existing gsm module on market.The Main Function of Logic control module 5 decodes the note that gsm module 4 is sent, and carry out the action of pilot relay 3 by high level voltage.
The principle of work that this device connects USB interface 7 by note is as follows: the mobile phone (being generally the mobile phone of computer owner) bound with computer sends password short message and sends the instruction of connecting USB interface 7, after password short message receives via gsm module 4, decoded by Logic control module 5, if password is correct, then Logic control module 5 exports direct current 12 volts of high level voltages to relay 3, connect the connecting line between USB mainboard connector 1 and hub 2 after direct current 12 volts of charged actions of relay 3, thus realize the connection of USB interface 7.
The principle of work that this device disconnects USB interface 7 by note is as follows: the mobile phone (being generally the mobile phone of computer owner) bound with computer sends password short message and sends the instruction disconnecting USB interface 7, after password short message receives via gsm module 4, decoded by Logic control module 5, if password is correct, then Logic control module 5 stops exporting direct current 12 volts of high level voltages to relay 3, disconnect the connecting line between USB mainboard connector 1 and hub 2 after direct current 12 volts of relay 3 dead electricity, thus realize the disconnection of USB interface 7.
The present invention utilizes the means such as gsm module 4, Logic control module 5 and relay 3 USB interface 7 of cell phone password short-message verification and computer to be combined, password correctly then performs the instruction being switched on or switched off USB interface 7, code error does not then perform the instruction being switched on or switched off USB interface 7, even if can not divulge a secret or illegal external connection when inserting USB flash disk or mobile phone so yet.The password short message only having the mobile phone of computer owner (prior and this computer is bound) to send is correct, just remote control can be switched on or switched off USB interface 7, efficiently avoid Intranet computer to divulge a secret or illegal external connection, all computers of each transformer station of national grid and office space can be widely used in, also can wide popularization and application in the unit that other have a security requirements, and it is simple and practical, stable and reliable for performance.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
