Description

Realize that microcomputer uses the control circuit device of multiple operating system

The utility model relates to a kind of microcomputer of realizing and uses the control circuit device of multiple operating system.

In the prior art; the computing machine of many hard disks is the problem for the hard-disk capacity deficiency that remedies computing machine; and can not solve the problem of using several operation systems at same computing machine; for example two operating systems of Windows and Unix can not be used on same hard disc of computer; user for frequent online or hobby computer game; computing machine is subjected to virus attack and infection easily; and when on the same hard disk of computing machine the vital document that needs protection being arranged; can not the effective isolation protected file; make it not be subjected to computer virus attack and infection; make many vital document infective virus or lose, bring the big loss of tool to the user.

The purpose of this utility model provides a kind of calculating function classification and storage file of many hard disks, realizes that microcomputer uses the control circuit device of multiple operating system.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of microcomputer of realizing uses the control circuit device of multiple operating system, its special being: described control circuit device comprises on-off circuit 1 and logic control circuit 2; The control signal A of switch, B be input logic control circuit 2 respectively, and the output terminal of logic control circuit 2 connects at least two on-off circuits 1 respectively, and described on-off circuit 1 is connected with corresponding a plurality of hard disk power interfaces.

The output terminal of above-mentioned logic control circuit 2 connects three, four on-off circuits 1 respectively.

Said switching circuit 1 is located between the power interface and computer power 4 of hard disk 3.

Said switching circuit 1 can be located at hard disk 3 inside.

Said switching circuit 1 also can be located at computer power 4 inside.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Fig. 1 is a block scheme of the present utility model;

Fig. 2 is second kind of embodiment block scheme of the present utility model;

Fig. 3 is the third embodiment block scheme of the present utility model;

Fig. 4 is the circuit diagram of control circuit of the present utility model;

Fig. 5 is the block scheme of on-off circuit of the present utility model;

Fig. 6 is the pulse diagram of control circuit of the present utility model;

Referring to Fig. 1, the utility model is made of on-off circuit 1 and logic control circuit 2, on-off circuit 1 can be a controllable silicon, relay, electronic switch, electronic relay, electric components such as hand switch, connect when on-off circuit is chosen by logic control circuit, make hard disk work to the hard disk power supply respectively, referring to Fig. 5.

When computing machine has two hard disks, Unix operating system has been installed on hard disk A, Windows operating system has been installed on hard disk B.On the microcomputer panel, can use two buttons.Corresponding control circuit A of button A and hard disk A; Corresponding control circuit B of button B and hard disk B.Control circuit and computer power switch can be installed together use, and the computer power switch is two paralleling switches.

Referring to Fig. 4, Fig. 6, the course of work of logic control circuit is as follows: AN is a pushbutton switch, because of the power initiation button of AN1, AN2 and microcomputer is installed together, when microcomputer starts, on-state, trigger T end is high level, the CP termination has the RC differentiating circuit to produce the decline level, trigger output terminal Q exports high level, and pilot relay J1 adhesive is powered to hard disk A, disconnect relay J 2 power supplys simultaneously, make relay J 1, J2 interlocking.

When using Unix operating system, promptly start hard disk A, its process is: press the button A, control circuit A connects, and sends control signal A and gives logic control circuit.Logic control circuit sends control signal, makes on-off circuit A conducting, and A provides working power to hard disk, hard disk A work; On-off circuit B is ended, do not provide working power to hard disk B, hard disk B does not work; Logic control circuit duty self-locking simultaneously.(this moment, release button also can not change the state of logic control circuit) finishes the start-up course of hard disk A.

When using Windows operating system, promptly start hard disk B, its process is: press the button B control circuit B and connect, send control signal and give logic control circuit.Logic control circuit sends control signal, makes on-off circuit B conducting, and B provides working power to hard disk, and hard disk B work ends switch A, does not provide working power to hard disk A, and hard disk A does not work, logic control circuit duty self-locking simultaneously.Finish the start-up course of hard disk B.

After startup is finished,,, this does not play any control action even pressing another control knob because of the logic control circuit self-locking yet.Logic control circuit self-locking reliability is extremely important, if hard disk A, B work simultaneously, the file of two hard disks might all damage.

Logic control circuit can connect three or four on-off circuits respectively, controls three or four hard disks respectively.

Referring to Fig. 2, on-off circuit A and on-off circuit B can be located at computer power inside respectively, and its principle of work specific embodiment 1 is identical, and on-off circuit also can be identical with specific embodiment 1 with logic control circuit.

Referring to Fig. 3, on-off circuit A and on-off circuit B also can be located at hard disk A and hard disk B inside respectively.

The utility model is that a kind of microcomputer of realizing uses the control circuit device of multiple operating system; it utilizes the duty of switch control hard disk; on-off circuit can directly adopt the working power of hand switch control hard disk, and this kind method also should belong to the utility model protection domain.

Certainly, control hard disk duty does not allow except that the control power supply its work, also can adopt its data entry mode of control, increases data strobe circuit in the hard disc data transmission circuit, data strobe circuit allows data to pass through when selected, does not allow data to pass through when not selected.The data decimation circuit passband is controlled by logic control circuit, and control procedure is same as above.This kind mode also should belong to the utility model protection domain.

Advantage of the present utility model is as follows:

Because the utility model adopts on-off circuit andlogic control circuit, can control a plurality of hard of computer Dish is worked respectively, realizes the interlocking between the hard disk; Thereby the classification that makes file is stored on the different hard disks, The computer of realizing many hard disks uses respectively several operation systems, has guaranteed that vital document is not subjected to computer virus Infect.
