Abstract
The utility model relates to a computer system hard disk switching controller, which is characterized in that a personal hard disk and a personal hard disk power supply control switch device are arranged out of a hard disk of a computer system. The personal hard disc is communicated with a computer CPU by a communication channel bus. Except that the utility model is additionally provided with the personal hard disc, the utility model also comprises a personal hard disc power supply, a communication channel breaking switch for breaking or switching on the personal hard disc and a communication channel of a computer, etc. When a hard disk of an online system of the computer is invaded by viruses or attacked by hackers, the personal hard disk is not online, and the personal information on the personal hard disk can not be invaded. The utility model uses hardware protection to substitute for software protection, which is convenient, quick and safe.
Description
The utility model belongs to a kind of Computer Memory Unit, particularly a kind of computer system hard switching control.
Taking precautions against the measure that computer virus is invaded and attacked for computer internet at present, all is to adopt ways such as anti-virus software and encryption.Because China does not have the intellecture property of self-designed CPU and corresponding operating system, and the software virus that occurs during computer internet and the deciphering means of the deciphering of encrypting are constantly upgraded, thereby the personal information that we are stored in hard disk on computers in the net operation is constituted a threat to.The means that above-mentioned utilization is handled computer software can not easyly protect personal information again very effectively, make it not suffer a loss.Or adopt and to be equipped with floppy disk in addition and to carry out slack storage etc. and leave and add that the slack storage mode is then operated and more numerous and diverse inconvenience, thereby become a hidden danger in the computer internet.
The purpose of this utility model provides and a kind ofly can realize being stored in when computer internet operated personal information in the hard disk without software protection and carry out computer system hard switching control easy, effective protection and overcome the deficiency of prior art.
The purpose of this utility model is achieved in that it promptly is outside an original CPU of computing machine and system disk, the additional individual hard disk and the gauge tap device of people's hard disk power supply one by one, and individual hard disk is connected with bus with the channel that computer CPU is asked.
Also can be outside an original CPU of computing machine and system disk, additional more individual hard disk, be the power supply that individual hard disk is powered, be communicated with its channel and one with bus between individual hard disk and CPU and be used to block or connect the channel blocking swtich that is communicated with channel between above-mentioned individual hard disk and computer CPU.
Also can be outside an original CPU of computing machine and system disk, additional individual hard disk, individual hard disk power supply, individual hard disk are communicated with bus with the channel of CPU, and one is used for selected change-over switch and the change-over switch that is used for blocking-up or connects individual disk C/D principal and subordinate wire jumper master end two-terminal of connecting master end and slave end of system disk C/D principal and subordinate wire jumper.
Advantage of the present utility model is because added individual hard disk again outside computing machine original system hardware; promptly adopt the dual system hard disk; again with cutting off or connect individual hard disk power supply or with blocking-up or connect that individual hard disk is communicated with channel with computer CPU or with the switching control of blocking or connect individual disk C/D principal and subordinate wire jumper master end two-terminal; make the personal information that is kept in the individual hard disk on computers during network operation because individual hard disk or do not have power supply; or it is communicated with being blocked of channel with CPU; or detect less than individual hard disk because of system; be that individual hard disk is not worked and made online " hacker " can't encroach on the personal information in the individual hard disk, thereby directly protected personal information not encroached on effectively.When off line if with described switching control switch to can connect individual hard disk power supply one side or switch to can connect individual hard disk and computer CPU be communicated with channel one side etc., but realize individual hard disk input duty, and can realize two dish connection carrying out message exchanges.The utility model makes its storage space strengthen with general computing machine comparison owing to increased individual hard disk on the one hand; on the other hand owing to can directly individual hard disk and switching control being loaded in the computing machine, so can realize that by controlling this hardware of individual hard disk protection personal information is not encroached on quickly and easily by changing the upper and lower net of change-over switch working position.
Do further commentary below in conjunction with the utility model embodiment
One of Fig. 1-the utility model formation and line synoptic diagram
Two of Fig. 2-the utility model formation and line synoptic diagram
Three of Fig. 3-the utility model formation and line synoptic diagram
The utility model also adopts computer CPU 1 usefulness bus 4 to reach with system disk 2 respectively to be connected 3 12 volts, 5 volts DC power supply by computing machine feed system hard disk 2 of individual hard disk by the channel of channel blocking swtich 11 with individual hard disk 3 as shown in Figure 2.Two terminals in the centre of change-over switch 12 are connected with each other logical, the end other end ground connection that links to each other with channel blocking swtich 11 gating ends in its left side pair of terminal, its right side pair of terminal can connect the Telecommunication Lines that needs and surf the Net and off line formation interlocking to control online usefulness, to make when online.The middle pair of terminal of change-over switch 13,14 is connected with each other respectively separately, and the left side pair of terminal then is connected with the two-terminal of the C/D wire jumper slave end 16 of the C/D wire jumper master end 6 of system disk 2, individual hard disk 3 respectively separately.And the right side pair of terminal separately respectively with system disk 2, individual hard disk 3 separately C/D wire jumper slave end 7 and the two-terminal in master end 15 be connected.
As shown in Figure 3 the utility model also adopt computer CPU 1 usefulness bus 4 respectively with the channel-connectivity of system disk 2 and individual hard disk 3, individual hard disk 3 12 volts, 5 volts DC power supply by computing machine feed system hard disk 2, two terminals in the C/D principal and subordinate wire jumper master end 6 of system disk 2 are communicated with respectively with two terminals in left side of change-over switch 10, two terminals of slave end 7 are communicated with two terminals in change-over switch 10 right sides respectively, and two terminals in the middle of the change-over switch 10 are interconnected.15 liang of connection terminals in C/D wire jumper master end of individual's hard disk 3 are connected with two terminals in change-over switch 18 left sides respectively, and slave end 16 is not set, and two terminals communicate with each other in the middle of the change-over switch 18, and change-over switch 18 right side pair of terminal then connect to Telecommunication Lines.Change-over switch 10 is connected and change-over switch 18 is connected Telecommunication Lines to the right to the left during online.It is opposite when 10,18 liang of switches are then with online when off line.
Above-mentioned change-over switch 8,9 and 10 and 12,13 and 14 and 10 and 18 also can adopt combined switch, stepping rotary switch, waver and key switch etc.
