Abstract
The invention provides a reliable mobile storage medium and an implementing method. The reliable mobile storage medium comprises a USB interface, at least two main control chip circuits and at least two storage chip circuits. The USB interface is connected with the main control chip circuits which are connected with the storage chip circuits respectively. In addition, power circuits are connected with the USB interface and connected with the master control chip circuits and the storage chip circuits respectively. By means of the scheme, written data can be backed up, so that data lost is avoided. Moreover, when one power circuit and one master control chip circuit are damaged, the redundant power circuit and the redundant master control chip circuit continue to work, and the reliability of the reliable mobile storage medium is improved.
Description
Technical field
What the present invention relates to is information security field, especially a kind of reliable mobile storage medium and implementation method.
Background technology
In the prior art, known technology is that current storage medium mainly comprises power circuit, storage chip circuit and control chip, and be single setting, in use, once one of them damages, mobile memory medium just cannot use, and will bring loss like this to user, and this is the weak point existing for prior art.
Summary of the invention
Object of the present invention is exactly for the deficiency existing for prior art, and the technical scheme of a kind of reliable mobile storage medium and implementation method is provided, the data of write can back up by the program, avoid the loss of data, and when power circuit and main control chip circuit damage, still there are the power circuit of redundancy and main control chip circuit to carry out work, improve the reliability of mobile memory medium.
This programme is achieved by the following technical measures: a kind of reliable mobile storage medium, comprise USB interface, the feature of this programme is: also comprise at least two main control chip circuit, at least two storage chip circuit, described USB interface is connected with main control chip circuit respectively, each main control chip circuit is connected with storage chip circuit respectively, has power circuit to be connected with USB interface in addition, and described power circuit is connected with main control chip circuit and storage chip circuit respectively.
Described main control chip circuit is two covers, and storage chip circuit is two covers.
Arranging the first change-over switch between described USB interface with main control chip circuit to be connected, being communicated with USB interface for switching different main control chip circuit.
Described power circuit is two covers.
Be provided with the second change-over switch between USB interface and power circuit, the second change-over switch is communicated with USB interface for switching different power circuits.
The second described change-over switch and the first change-over switch link.
The method that reliable mobile storage medium realizes, is characterised in that and comprises the steps:
1) mobile memory medium is inserted computing machine, if None-identified, then enters step 2), otherwise enter step 3)
2) switch main control chip circuit by the first change-over switch, then enter step 7), and send warning;
3) judge whether storage chip circuit has can read, if cannot read, then enter step 4), otherwise, then enter step 5);
4) main control chip circuit reads data from unspoiled storage chip circuit; Send warning;
5) if stored in data in mobile memory medium, then enter step 6), if read data, step 7) is entered;
6) in mobile memory medium stored in data, with USB interface to the main control chip circuit being in connection status by stored in data be written in all storage chip circuit;
7) from a storage chip circuit, data are read.
Described step 2) in, there are the second change-over switch and the first change-over switch to link, when switching main control chip circuit, also power circuit switched.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to there being the storage chip circuit of redundancy in this scenario, when storing data, in all storage chip circuit, store data, like this once when having storage chip circuit to damage, main control chip circuit still can read data from other storage chip circuit, mobile memory medium now just needs to change, can not write data again, write data, just cannot ensure reliability; There is the main control chip circuit of redundancy, when a main control chip circuit damages, this mobile memory medium of computing machine None-identified, other main control chip circuit can be switched to like this by change-over switch, such computing machine just can continue to carry out data communication with mobile memory medium, but now have main control chip circuit to damage, then this mobile memory medium just needs to change; And when changing main control chip circuit, also power circuit is changed, ensure that effective operation of whole mobile memory medium.As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
