Abstract
The utility model discloses a data-erasing device, comprising: an embedded system, a single chip and a keyboard; wherein, the embedded system is provided with an interface for externally connecting a storage device; the embedded system executes an erasing program and carries out communications through the interface; the keyboard is connected with the single chip, thus realizing to control the embedded system. The data-erasing device can erase data for a plurality of storage devices simultaneously without revealing the storage information, and can stop erasing data for the storage device at any time. The data-erasing device is high in data-erasing speed, thorough in data erasing, and convenient for carrying, without any damage to the storage device.
Description
Technical field
The utility model relates to a kind of data erasure apparatus.
Background technology
Along with the development of infotech, the application of computer is more and more general, and people use movable memory equipment to come backup information, transfer information through regular meeting.When these data no longer need, just need be with data erase, store other data with vacating space, but directly delete on computers, not only speed is slow, and can not thoroughly clear data, relating to the data of company's secret or national security for some especially, safe mode is eliminated data more to need a kind of safety.Just lacking at present a kind of equipment that is specifically designed to data erase, though the multiple software of wiping data in the memory device that is specifically designed to is arranged, but it needs configuration computer when operation, cause the wasting of resources, waste time and energy, and when memory device linked to each other with computer, other people are easy to open memory device, thereby the leakage memory contents, and inefficiency can't be operated to a plurality of memory devices simultaneously.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of data erasure apparatus that can carry out the operation of data erase simultaneously to a plurality of memory devices, it can stop wiping memory device at any time, and can not reveal memory contents, have erasing speed fast, harmless to memory device, wipe advantages such as thorough, easy to carry.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Data erasure apparatus comprises embedded system, single-chip microcomputer and keyboard, and embedded system is provided with the interface that is used for external memory device, embedded system is carried out the program of wiping, and communicate by serial ports with single-chip microcomputer, keyboard links to each other with single-chip microcomputer, realizes the control to embedded system.
Described embedded system adopts LINUX operating system as operation platform.
Described embedded system is provided with USB2.0 interface and ide interface.
Described single-chip microcomputer can connect charactron.
After adopting such scheme, the utility model can be by increasing interface, come simultaneously a plurality of memory devices to be carried out the operation of data erase, it can stop wiping memory device at any time by Keyboard Control, because there is not display interface, so the hidden danger that data leaks when not having obliterated data, have erasing speed fast, harmless to memory device, wipe advantages such as thorough.In addition, because body is small and exquisite, has advantage easy to carry.The utility model also can be wiped progress by the synchronous video data of charactron.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is a workflow of the present utility model;
Fig. 3 is a structural representation of the present utility model.
Embodiment
As shown in figures 1 and 3, the data erasure apparatus that the utility model disclosed comprises embedded system 1, single-chip microcomputer 2 and keyboard 3, and wherein embedded system 1 is provided with interface 11, can the external memory device that needs obliterated data.Its interface 11 can be USB2.0 interface and ide interface, in order to identification USB flash disk and hard disk, also can increase interface 11 as required.Embedded system 1 adopts LINUX operating system as operation platform, and embedded system 1 is carried out and wiped program, and communicates with single-chip microcomputer 2 by serial ports.Embedded system 1 can connect charactron.Keyboard 3 links to each other with single-chip microcomputer 2, and the operation of control single chip computer 2, realizes the control to embedded system.
With reference to figure 2, when data erasure apparatus is started working, embedded system begins to load automatically the program of wiping, after loading is finished, enter step 13, wipe the interface 11 on the program scanning embedded system 1, according to step 14 identification with enumerate the memory device that is connected on the embedded system 1, and the information that will obtain on the gained memory device by serial ports is sent to single-chip microcomputer 2.If there is not memory device to insert embedded system, then return step 13, continue scan interface, the memory device that need wipe is arranged if judge, then enter step 15, can select whether begin erase process this moment by keyboard 3, and single-chip microcomputer 2 is delivered to the operating system of embedded system with the input signal of keyboard 3, selects "No", return step 13, select "Yes", enter step 16, require user's selective erasing pattern.The utility model is supported three kinds of erasing modes: wipe once with 00; Wipe once with FF; Wipe once with 00 earlier, wipe once with FF again, wipe once with 00 at last, can select by keyboard 3 as required.In erase process, wipe the continuous repeating step 18 of program meeting, whether keyboard scan has "signal for " stop ", if need stop, the program of then wiping is out of service, returns step 13, the user can carry out shut-down operation by " stopping " button on the keyboard at any time, stops the operation of the program of wiping.The utility model also can be on single-chip microcomputer 2 external charactron, embedded system 1 will be wiped the ruuning situation information transmission of program at any time to single-chip microcomputer 2, show the progress of wiping synchronously by charactron.
The utility model superiority is: owing to there is not the display port, be not wiped free of so can not exist The hidden danger that content is disclosed, it is wiped software and adopts multi-thread design, can be simultaneously many to what insert Individual memory device operates, and have erasing speed fast, harmless to memory device, wipe The advantage such as thoroughly.
