Abstract

The utility model relates to a computer which can switch storage devices, and comprises a host, a display, a mouse and a keyboard, wherein at least two independent storage devices which are generally computer hard disks are arranged in the host, a casing is equipped with transfer switches which are correspondingly connected with different storage devices, and a controller which is used to switch the storage devices is further arranged in the host. A computer can be classified by the computer which can switch storage devices according to functions, software systems are placed in different relatively independent computer main storage devices, during the using process of a computer, corresponding computer storage devices are opened or closed through the computer which can switch storage devices, thereby achieving the purpose of increasing the stability of the computer.

Description

The computer of changeable memory device

Technical field

The present invention relates to a kind of computer of changeable memory device.

Background technology

Along with popularizing of computer applications; we have lived in the society of a dependence computer; yet no matter be the conventional desktop computer; still various software faults all always appear in notebook computer easily; especially in some specific area, have influence on our operate as normal, life through regular meeting.After all, these computer software fault overwhelming majority are because the opening of computer software systemic-function " setting " causes.Concrete reason is, people can be according to own needs exploitation and composition computer program to computer function, in some cases even can revise the computer software system program that others has developed, thus one, we then can be often in the use of computer own or other people computer function are changed consciously or unconsciously, thereby caused the generation of most of computer glitch.

Though there is a kind of switchable type multi-memory host computer at present, can realize the switching use between the storer, but this computer is in the switchable memory process, need to turn-off earlier the power switch of computer, and the connecting line complexity between change-over switch and the memory power, it is bigger that general computer user is implemented difficulty, and might cause the host computer damage of internal device because of misoperation.

Summary of the invention

The purpose of this utility model is to improve above-mentioned deficiency of the prior art and computer that a kind of changeable memory device is provided, can be with data message by functional classification, place different relatively independent computer memory devices, solved the problem that does not need shutdown earlier could switch memory device, the utility model fitting operation is simple simultaneously, has simplified former switching device shifter line complicated problems in the main frame.

The purpose of this utility model reaches by following measure:

A kind of computer of changeable memory device comprises main frame, display, mouse, keyboard, and two independent memory device are installed in the described main frame at least, and cabinet is provided with the change-over switch corresponding with different storage device.

Be provided with in the described main frame and be used for the controller of control store equipment.

Described change-over switch can be mechanical switch, electronic touch button, knob or is independent of the switch switching device shifter of main frame.

Described memory device can be disk sort storage medium or chip class storage medium.

Advantage of the present utility model is:

The user is in switching the memory device process, and this device can make computer restart automatically, need not to turn-off in advance computer power, and is user-friendly; To be placed between controller in the main frame and each parts of computer line simple for this device in addition, and all adopt the computer general standard interface, and the computer that makes the common computer user reequip changeable memory device voluntarily becomes possibility.

Description of drawings

The computer synoptic diagram of the changeable memory device of Fig. 1;

The computer principle schematic of the changeable memory device of Fig. 2;

Fig. 3 switch controller master chip pin figure.

Embodiment

As shown in Figure 1, the cabinet 1 of changeable memory device computer is provided with rotary switch 2, memory device 3 is installed in the cabinet 1 and switches storage device controller 4, is electrically connected by lead between rotary switch 2, memory device 3 and the switching storage device controller 4.

As shown in Figure 2, A, B, C are the standard PC case power interface, and D is that standard PC case is restarted the wire jumper interface, and X is the N+1 shunt cable, and Y is restarted wire jumper for the standard computer main board.Computer user is when starting computer, and the memory device working group of acquiescence starts working, and the user places needed memory device position shelves to get final product change-over switch when wanting that carrying out memory device switches in the computer use.In the rotary switch handoff procedure, switch controller at first can be at mainboard re-starting control circuit signal of Y end output, can connect selected memory device automatically simultaneously, here memory device can be divided into some groups according to function, and this moment, computer began to restart and the memory device that enters on is started working.

As shown in Figure 3, the control master chip that switch controller adopts is HK19F-DC-12V-SH, and the 1-2 pin is the input control end; 3-8 pins are signal output part.

When the voltage of chip pin 1 is 12V, during pin two ground connection,

chip pin

3 and 5 is an off-state, this moment stable duty when working for booting computer; When the voltage of chip pin 1 is 0V, during pin two ground connection,

chip pin

3 and 5 is an on-state, be in the computer memory device this moment and switch the moment duty, utilize the moment of this

chip pin

3 and 5 to connect at this, give short-circuit signal of computer main board re-starting control circuit interface, make computer enter automatically and restart duty.
