C) central controller will read data in the extraneous storage card, and be that extraneous data-carrier store can the recognition data form with its Data Format Transform, and these data are write entry data memory.
In the described step c), central controller at first writes buffer memory with the data in the extraneous storage card, and then, the extraneous data-carrier store of central controller controls reads the data in the buffer memory.
In the described step c), the data in the extraneous storage card are stored in the memory storage simultaneously.
Described data-carrier store interface is a USB interface.
The invention has the beneficial effects as follows, 1) is provided with at least one card reader interface and at least one data-carrier store interface, pass through central controller controls, from the card reader interface reading of data, from data-carrier store interface output data, realize the data transmission between storage card and the data-carrier store, do not need computer assisted; 2) volume is little, and is easy to carry, just can realize that by this device the unloading of file copies, thereby greatly convenient for users.
Description of drawings
Fig. 1 is the structured flowchart of a kind of portable data switch of present embodiment.
Embodiment
As shown in Figure 1, a kind of portable data switch of present embodiment comprises power supply and central controller, at least one card reader interface, at least one data-carrier store interface, buffer memory, display module, operational module and the memory storage of being powered by this power supply.Card reader interface is used for can plugging with extraneous storage card and is connected, and this card reader interface is connected with central controller and as data-out port.The data-carrier store interface is used for can plugging with extraneous data-carrier store and is connected, and this data-carrier store interface is connected with central controller and as Data Input Interface.When the data of storage card were carried out unloading and duplicated to external world, buffer memory was used to improve the speed that data are duplicated as the temporary storage between central controller and memory storage, the extraneous data-carrier store.Memory storage is connected with central controller, central controller can be optionally with the data storage in the extraneous storage card in this memory storage.Display module is connected with central controller, it can show the work state information of whole portable data switch, and this work state information is as the file directory of operation interface, extraneous storage card, the file directory of extraneous data-carrier store, file copy progress etc.Operational module is connected with central controller, and it is used for giving central controller input operation instruction for the user, by the cooperation of operational module and display module, can offer interactively operation interface of user.Central controller is used to control, coordinate the each several part of this portable data switch, this central controller solidifies or has inserted underlying operating system program and application program, and driver, the file of driver, display module and the operational module of the driver of this application program such as power management routines, extraneous storage card, the driver of extraneous data-carrier store, memory storage reads and the program transmitted etc.This central controller also can be embedded with the storage unit that is used for stored programme and data, as RAM, ROM etc.
Card reader interface can be connected thereby can plug with the extraneous storage card of corresponding data form for XD card, SD card, TF card, memory block interface, mmc card interface, CF card, MS card etc.The data-carrier store interface can be connected thereby can plug with the data-carrier store with corresponding interface, as the portable hard drive of prior USB interface for USB interface, 1394 interfaces etc.Memory storage such as hard disk or flash memories.Display module such as LCD module, led module etc.Operational module such as keyboard, button, touch-screen etc.Central controller such as microprocessor.
The method for interchanging data of above-mentioned portable data switch comprises the steps:
1) after the start, receive the operational order of user by the operational module input, System self-test, central controller detects the connection status of card reader interface and data-carrier store interface;
2) data layout of central controller reading card device interface and data-carrier store interface is discerned, and promptly the extraneous storage card that is connected with these interfaces and the data layout of extraneous storer is discerned;
3) central controller detects the fileinfo of the extraneous storage card that is connected with card reader interface, and file directory is shown by display module, and prompting user operation;
4) central controller receives the operational order of user's input, with extraneous data-carrier store that the data-carrier store interface is connected in set up file directory, central controller reads the data in the extraneous storage card, and Data Format Transform that should external world's storage card is that extraneous storer can the recognition data form, and the data storage after will changing is in buffer memory;
5) the extraneous data-carrier store of central controller controls reading of data from buffer memory, and the progress msg of data read shown by display module.
In the present embodiment, the data in the extraneous storage card directly are stored in the extraneous data-carrier store; Certainly, in the memory storage that data also can directly be stored in central controller is connected in the extraneous storage card; Perhaps these data are stored in extraneous data-carrier store and the memory storage simultaneously.Card reader interface can have one, also two or more can be arranged; The data-carrier store interface can have one, also two or more can be arranged.When carrying out data conversion storage, a card reader interface and the work of a data memory interface are only arranged, and respectively as data output end and data input pin.For this portable data switch, when carrying out data conversion storage, it uses as main frame (Host), function such as existing computing machine.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
