The control device comprises a microprocessor, a relay drive part, a computer power supply control relay, a computer power supply and an interface conversion part, wherein one path of the output port of the microprocessor is connected with a computer serial port through the interface conversion part, and the other path is connected with the input port of the relay drive part; the output port of the relay drive part is connected with the input port of the computer power supply control relay; and the computer power supply control relay is connected with the computer power supply. The control device has the benefits of realization of control combination optimization, simple structure, and easiness in popularization and application, and can absolutely ensure the safety of the user computer information.
Description
Technical field
The utility model relates to computer safety field, relates in particular to a kind of information security of computer network control device.
Background technology
The fast development of Along with computer technology and network makes computing machine become people's indispensable instrument in work, living and studying.Equally, development of computer network has brought potential safety hazard also for subscriber computer information, and the network information is stolen, information attack, virus disseminating etc. all exist all the time and develop.At present, in order to solve the subscriber computer information security issue, people have taked many measures and method, and the one, adopt and isolate card technique; The 2nd, computing machine adopts two kinds of different operating systems, control two methods such as hard disk respectively, but said method has problems all, can't avoid " network hacker " to steal user profile exactly, can not guarantee being perfectly safe of user's computer information.
The utility model content
The utility model provides novel information security of computer network control device to the above-mentioned deficiency that prior art exists, and the selectivity of the two-port through double-point double-throw switch can be guaranteed being perfectly safe of subscriber computer information.
The purpose of the utility model is to realize through following technical scheme:
A kind of information security of computer network control device; Comprise microprocessor, relay drive part, computer power supply pilot relay, computer power supply, interface conversion part; Said output end of microprocessor mouth one tunnel is connected with serial ports of computers through interface conversion part; Another road is connected with the input port of relay drive part; The output port of said relay drive part is connected with the input port of computer power supply pilot relay, and said computer power supply pilot relay is connected with computer power supply.
Said computer power supply is connected with the common computer hard disk via a dual-port of double-point double-throw switch, and another dual-port is connected with secret hard disk, and said common computer hard disk is connected with network interface card, computer network hub respectively via the network switch.
The utility model beneficial effect: can guarantee being perfectly safe of subscriber computer information, control combination realizes optimization, and is simple in structure, is easy to popularize.
Description of drawings
Fig. 1 is the described information security of computer network control device of a utility model structural representation.
Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below:
As shown in Figure 1; A kind of information security of computer network control device of the utility model; Comprise microprocessor, relay drive part, computer power supply pilot relay, computer power supply, interface conversion part; Said output end of microprocessor mouth one tunnel is connected with serial ports of computers through interface conversion part, and another road is connected with the input port of relay drive part; The output port of said relay drive part is connected with the input port of computer power supply pilot relay; Said computer power supply pilot relay is connected with computer power supply; Said computer power supply is connected with the common computer hard disk via a dual-port of double-point double-throw switch; Another dual-port is connected with secret hard disk, and said common computer hard disk is connected with network interface card, computer network hub respectively via the network switch.
Novel information security of computer network control device working method is: open the subscriber computer power supply; Subscriber computer is under original state; Automatically get into " safe mode ", this moment, double-point double-throw switch was connected to secret hard disk one end, and subscriber computer and computer network break off; The computer information security hard disk that has information safety protection powers up, and the information of common computer hard disk writes and is employed the software cancellation.
In the time will being replaced by " grid connect mode "; The user controls through operating application program; This moment, double-point double-throw switch was connected to common computer hard disk one end; The power supply that has the computer information security hard disk of information safety protection is disconnected, and the information of common computer hard disk writes and is employed software and opens, and subscriber computer is connected with computer network.Since subscriber computer the networking state under, the power supply of secret hard disk is disconnected, thus secret hard disk do not work, it is hereby ensured subscriber computer the networking state under do not stolen security information by " networking hacker ".
The utility model is divided into two kinds of mode of operations with subscriber computer, and a kind of is " safe mode ", and another kind is " grid connect mode ".The working mode change of subscriber computer is by the own manual operation of user; " network hacker " can't change the mode of operation of subscriber computer on the net; Can under the state of subscriber computer networking, effectively protect being perfectly safe of subscriber computer information; No matter " network hacker " takes which type of technical measures and means, all can't steal the information in the subscriber computer; And double-point double-throw switch has solved secret hard disk and network switch power supply automatic power problem simultaneously, has simplified annexation, has realized optimized combination of circuits, has accomplished the automatic interaction between the computing machine parts.
