Description
Technical field
The utility model relates to field of information security technology, is specifically related to a kind of computer information safe device.
Background technology
Computer Data Security is a problem of widely being paid close attention to by the user.For the computer user, loss of data, data by the hacker, stolen and computing machine by virus attack, be the common form of threat data safety.For protection calculation machine data safety, prevent the personal computer leakage of information, people have adopted a lot of software approach to prevent that computing machine from being attacked by internet worm, in case norm is according to potential safety hazard.
Yet common anti-virus software, can only be used for preventing known virus, helpless to emerging virus; Therefore, when user's computer internet, very difficult assurance is not invaded by internet worm, will cause thus computer hard disk data damaged.
Usually use two hard disks in order to address the above problem people, during a hard disk online, another hard disk is the important file of storage, but has in use following shortcoming: the hard disk of one, storing important file is not connected with the hard disk of online, inconvenience during copied files; Two, the hard disk of storing important file is easily used by other people, causes the dangerous of information.
Summary of the invention
The purpose of this utility model is to provide a kind of computer information safe device, and it can be in the situation that guarantee that information security makes two hard disk conductings, easy to use, and can prevent that other people from using the hard disk of storing information, easy and simple to handle.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises microprocessor U1, switch S1, pilot lamp one HL1, pilot lamp two HL2, password drive circuit board D1, cipher control panel D2, relay K M, the end of microprocessor U1 is connected with 1 pin of switch S1, 2 pin of switch S1 are connected with the end of pilot lamp one HL1, the other end of pilot lamp one HL1 respectively with hard disk 1, wireless network card 3 connects, 3 pin of switch S1 are connected with an end of pilot lamp 22, the other end of pilot lamp 22 is connected with the end of password drive circuit board D1, cipher control panel D2 is connected with password drive circuit board D1, the other end of password drive circuit board D1 is connected with an end of relay K M coil, the other end of relay K M coil is connected with hard disk 22, hard disk 1, hard disk 22 is connected with the two ends of relay K M normally opened contact respectively.
Principle of work of the present utility model is: the hard disk of using when hard disk 1 is online, the hard disk that hard disk 22 is used for store files, when needs are surfed the Net, 1 pin of switch S1 and the connection of 2 pin are got final product, now pilot lamp one HL1 is bright, can clearly find out the duty of computing machine, when the needs store files, 1 pin of switch S1 and 3 pin are connected, can use hard disk 22 by cipher control panel D2 input password simultaneously, when relay K M coil obtains when electric, relay K M normally opened contact closure, now hard disk 22 and hard disk one 1 conductings, can copied files, easy to use, easy and simple to handle.
The utlity model has following beneficial effect: it can be in the situation that guarantee that information security makes two hard disk conductings, easy to use, and can prevent that other people from using the hard disk of storing information, easy and simple to handle.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises microprocessor U1, switch S1, pilot lamp one HL1, pilot lamp two HL2, password drive circuit board D1, cipher control panel D2, relay K M, the end of microprocessor U1 is connected with 1 pin of switch S1, 2 pin of switch S1 are connected with the end of pilot lamp one HL1, the other end of pilot lamp one HL1 respectively with hard disk 1, wireless network card 3 connects, 3 pin of switch S1 are connected with an end of pilot lamp 22, the other end of pilot lamp 22 is connected with the end of password drive circuit board D1, cipher control panel D2 is connected with password drive circuit board D1, the other end of password drive circuit board D1 is connected with an end of relay K M coil, the other end of relay K M coil is connected with hard disk 22, hard disk 1, hard disk 22 is connected with the two ends of relay K M normally opened contact respectively.
The principle of work of this embodiment is: the hard disk of using when hard disk 1 is online, the hard disk that hard disk 22 is used for store files, when needs are surfed the Net, 1 pin of switch S1 and the connection of 2 pin are got final product, now pilot lamp one HL1 is bright, can clearly find out the duty of computing machine, when the needs store files, 1 pin of switch S1 and 3 pin are connected, can use hard disk 22 by cipher control panel D2 input password simultaneously, when relay K M coil obtains when electric, relay K M normally opened contact closure, now hard disk 22 and hard disk one 1 conductings, can copied files, easy to use, easy and simple to handle.
This embodiment has following beneficial effect: it can be in the situation that guarantee that information security makes two hard disk conductings, easy to use, and can prevent that other people from using the hard disk of storing information, easy and simple to handle.
