A pin I of a power supply drive is connected with one end of a switch; the other end of the switch is connected with one end of a coil of a relay I; the other end of the coil of the relay I is connected with a network card; a pin 2 of the power supply drive is connected with one end of a normally-open contact of the relay I; the other end of the normally-open contact of the relay I is connected with a main hard disk drive; the main hard disk drive is connected with a main hard disk; a pin 3 of the power supply drive is connected with one end of a normally-closed contact of the relay I; the other end of the normally-closed contact of the relay I is connected with a secondary hard disk drive; the secondary hard disk drive is connected with a secondary hard disk; the secondary hard disk is connected with one end of a normally-open contact of a relay II; the other end of the normally-open contact of the relay II is connected with the main hard disk. The switching device has the advantages of fewer components, low cost, simpleness and convenience in operation, accuracy in control and simple structure.
Description
Technical field
The utility model relates to field of computer technology, is specifically related to a kind of Dual harddisk drive switching apparatus.
Background technology
Computer Data Security is a problem of widely being paid close attention to by user.For computer user, loss of data, data by hacker, stolen and computing machine by virus attack, be the common form of threat data safety.For protection calculation machine data safety, prevent 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; But common anti-virus software can only be used for anti-known viruse, 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.
In order to address the above problem people, usually use two hard disks, during a hard disk online, another hard disk is the important file of storage, it is cumbersome that but it switches two hard disks, need to use several switches, multiple components and parts and circuit to realize, its cost is high, uses inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of Dual harddisk drive switching apparatus, and the components and parts that it uses are few, and cost is low, easy and simple to handle, and precise control, simple in structure.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises power supply driver 1, network interface card 2, Primary Hard Drive driver 3, secondary hard disk drive 4, Primary Hard Drive 5, secondary hard disk 6, it also comprises switch S 1, relay one KM1, relay two KM2, 1 pin of power supply driver 1 is connected with one end of switch S 1, the other end of switch S 1 is connected with one end of relay one KM1 coil, the other end of relay one KM1 coil is connected with network interface card 2, 2 pin of power supply driver 1 are connected with one end of relay one KM1 normally opened contact, the other end of relay one KM1 normally opened contact is connected with Primary Hard Drive driver 3, Primary Hard Drive driver 3 is connected with Primary Hard Drive 5, 3 pin of power supply driver 1 are connected with one end of relay one KM1 normally closed contact, the other end of relay one KM1 normally closed contact is connected with secondary hard disk drive 4, secondary hard disk drive 4 is connected with secondary hard disk 6, secondary hard disk 6 is connected with one end of relay two KM2 normally opened contacts, the other end of relay two KM2 normally opened contacts is connected with Primary Hard Drive 5.
Principle of work of the present utility model is: when needs are surfed the Net, press switch S 1, now network interface card 2 is connected, relay one KM1 coil obtains electric, relay one KM1 normally opened contact closure, Primary Hard Drive 5 is switched on, relay one KM1 normally closed contact disconnects, secondary hard disk 6 is disconnected, when needs are stored information or during from Primary Hard Drive 5 copied files, switch S 1 is disconnected, network interface card 2 power-off, relay one KM1 coil losing electricity, relay one KM1 normally opened contact disconnects, relay one KM1 normally closed contact closure, secondary hard disk 6 is switched on, now relay two KM2 coils obtain electric, relay two KM2 normally opened contact closures, at this moment can be from the interior copied files of Primary Hard Drive 5, safety that simultaneously also can guarantee information.
The utlity model has following beneficial effect: the components and parts of use are few, and cost is low, easy and simple to handle, and precise control, simple in structure.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
