Description
Technical field:
The utility model relates to a kind of computing machine with hard disk information safety feature, belongs to field of computer technology.
Background technology:
Computing machine is a kind ofly can according to the program of having set, carry out voluntarily the electronic equipment of data processing.Conventionally our said computing machine refers to PC, and it is comprised of a plurality of parts such as CPU, mainboard, internal memory, power supply, cabinet, video cards.Computing machine is dimerous by hardware system and software systems.The hardware unit of traditional electrical brain system generally can be divided into input block, output unit, ALU, control module and mnemon, and wherein ALU and control module are collectively referred to as CPU (central processing unit).
Existing computing machine adopts software that the safety that password is protected hard disk internal information is set, not comprehensive but software arranges cryptoguard, once password is cracked, the information of hard disk can be stolen, uses inconvenient.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of computing machine with hard disk information safety feature.
A kind of computing machine with hard disk information safety feature of the present utility model, it comprises main frame, display, input media, hard disk, it also comprises microprocessor, coded lock, connector, relay, main frame by data line respectively with display, input media connects, microprocessor, connector, relay is installed in main frame, coded lock is arranged on main frame outside surface, coded lock is connected with microprocessor, microprocessor is connected with one end of relay coil, the other end of relay coil is connected with one end of relay normally open contact, the other end of relay normally open contact is connected with connector, connector is connected with hard disk.
As preferably, described microprocessor is 32-bit microprocessor.
As preferably, described coded lock is electronic type coded lock or card-scanning type coded lock.
The beneficial effects of the utility model: adopt mechanical mode to guarantee the safety of hard disk internal information, easy to use, easy and simple to handle, simple in structure, and cost is low.
Accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electrical schematic diagram of the present utility model.
In figure: 1-main frame; 2-display; 3-input media; 4-hard disk; 5-microprocessor; 6-coded lock; 7-connector; KM-relay.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1-2, this embodiment is by the following technical solutions: it comprises main frame 1, display 2, input media 3, hard disk 4, it also comprises microprocessor 5, coded lock 6, connector 7, relay K M, main frame 1 by data line respectively with display 2, input media 3 connects, microprocessor 5, connector 7, relay K M is installed in main frame 1, coded lock 6 is arranged on main frame 1 outside surface, coded lock 6 is connected with microprocessor 5, microprocessor 5 is connected with one end of relay K M coil, the other end of relay K M coil is connected with one end of relay K M normally opened contact, the other end of relay K M normally opened contact is connected with connector 7, connector 7 is connected with hard disk 4.
Further, described microprocessor 5 is 32-bit microprocessor.
Further, described coded lock 6 is electronic type coded lock or card-scanning type coded lock.
The principle of work of this embodiment is: during start, by coded lock 6 input passwords, microprocessor 5 receives signal, when the password of inputting is correct, pilot relay KM coil obtains electricly, and now relay K M normally opened contact is closed, and hard disk 4 is switched on and can normally works, when shutdown, relay K M coil losing electricity, hard disk 4 quits work, easy to use, can guarantee the safety of hard disk information, and easy and simple to handle.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
