Description
Technical field
The present invention relates to a kind of virtual method of storage medium, refer to especially a kind of virtual method of realizing storage medium at DPF.
Background technology
Development along with electronic technology, various electronic products have replaced the traditions of the past product introduction in the daily life gradually, as taking pictures now, adopt digital camera, adopt the camera of film to be eliminated gradually, the photograph that digital camera is shot is stored in the storage card with the form of document usually, the user can be sent to these photographs in the computer, then at the computer inediting or watch these photographs, but when watching these photographs or photograph album at every turn, the user all to open computer, very inconvenience.
In order to make things convenient for the user to browse these photographs, DPF is adopted by people gradually, and photograph deposits in the DPF, and user's function digit photo frame just can be browsed, and DPF is generally smaller and more exquisite, can furnish easily at home as decorating.The DPF that has at present network function has begun to have grown up, and when a more than number of units code photo frame exists in the family, can't communicate each other.The user takes out storage card in digital camera, insert when browsing in the slot of a number of units code photo frame, and other DPF can not be seen or copy simultaneously.If want to browse at other DPF, storage card need to be inserted on that number of units code photo frame; And, if want the photograph in the internal storage of DPF is copied in other photo frames, at first need to insert a storage card, copy external memory card in the memory internally, take again this storage card copy photograph in the internal storage of target DPF.So, if can having external memory card and the internal storage of seeing mutually the other side between the DPF of network function and reading and writing, can greatly improve the usability of DPF.
Summary of the invention
In view of above content, be necessary to provide the virtual method at DPF realization storage medium that to access mutually between a kind of a plurality of DPF.
A kind of virtual method of realizing storage medium at DPF, it may further comprise the steps:
One first DPF arranges its storage medium and is shared by other DPF in a network connection;
One second DPF is by the storage medium of this web search to described the first DPF, and described the second DPF is presented at the device identification of described the first digital photo frame stores medium in its list of devices;
Described the second DPF sends facility information request to storage medium to described the first DPF;
Described the first DPF echo message request, and the facility information of its storage medium passed to described the second DPF, described the second DPF creates the virtual unit of corresponding the first digital photo frame stores medium;
Described the second DPF by virtual unit to the first DPF read, write operation.
Compared to prior art, the present invention realizes that at DPF better embodiment second DPF of the virtual method of storage medium creates corresponding virtual unit, will have the similar equipment of the storage medium with described the first DPF on described the second DPF and use, so that can access mutually between a plurality of DPF.
Description of drawings
Fig. 1 is that the present invention is at the schematic diagram of the better embodiment of the virtual method of DPF realization storage medium.
Fig. 2 is that the present invention is at the theory diagram of the better embodiment of the virtual method of DPF realization storage medium.
Fig. 3 is that the present invention is at the flow chart of the better embodiment of the virtual method of DPF realization storage medium.
Embodiment
See also Fig. 1, the present invention realizes that at DPF the better embodiment of the virtual method of storage medium comprises one first DPF 10, one second DPF 20 and a switch 30.Described the first DPF 10 is provided with one for the card reader 11 and the network card (this network card can be Ethernet card, wireless network card or other communication media interface) that read external memory card.Described the second DPF 20 is provided with one for the card reader 12 and the network card (this network card can be Ethernet card, wireless network card or other communication media interface) that read external memory card.Described the first DPF 10 is connected on the described switch 30 with described the second DPF 20.
See also Fig. 2, module one is for operating in the program on described the first DPF 10, and module two is for operating in the program on described the second DPF 20.After 10 starts of described the first DPF, module one is in 10 operations of described the first DPF.Module one stores the machine name and the exterior storage card information that is connected on described the first DPF 10 of described the first DPF 10.Whether described the first DPF 10 can arrange himself external memory card and internal memory device and can be shared by other DPF.
After 20 starts of described the second DPF, module two is in 20 operations of described the second DPF.When described the second DPF 20 needs access storage media, module two searches out shared external memory card and the internal memory device of permission of described the first DPF 10, and device identification is presented in the storage medium tabulation of described the second DPF 20, described the second DPF 20 can select to browse the storage medium of described the first DPF 10.
Please consult simultaneously Fig. 3, Fig. 3 realizes the flow chart of the virtual method of storage medium for realizing the present invention at DPF, and it may further comprise the steps:
Step 10: described the first DPF 10 and described the second DPF 20 start respectively, and all are connected on the described switch 30.
Step 11: at described the first DPF 10 its external memory card and internal memory device being set can be shared by other DPF.
Step 12: described the second DPF 20 is searched for by module two, searches the storage medium whether other DPF is arranged in this network.
Step 13: described the second DPF 20 searches external memory card and the internal storage on described the first DPF 10, described the second DPF 20 is presented at the external memory card on described the first DPF 10 and the internal storage mode with device identification in its list of devices, wherein, described device identification comprises the title of DPF, the title of external memory card and the title of internal storage.
Step 14: choose the storage medium of described the first DPF 10 of use to operate at described the second DPF 20.
Step 15: described the second DPF 20 sends facility information request to storage medium to described the first DPF 10 by module two.
Step 16: described the first DPF 10 passes to described the second DPF 20 with the facility information (storage media types, capacity etc.) of equipment of itself, the module two of described the second DPF 20 creates corresponding virtual unit, and will have external memory card and the similar equipment of internal storage with described the first DPF 10 on described the second DPF 20 can use.
Step 17: when described the second DPF 20 reads the data of described the first DPF 10, send the parameter (device identification, correspondence position, data length) of reading out data to described the first DPF 10, described the first DPF 10 returns to described the second DPF 20 after with these data readings; Described the second DPF 20 is during to described the first DPF 10 data writing, send the parameter (device identification, correspondence position, data length, data) of data writing to described the first DPF 10, return to described the second DPF 20 results after described the first DPF 10 writes data.
Step 18: the access of 20 pairs of virtual units of described the second DPF finishes.
The present invention realizes that at DPF the virtual method of storage medium has ease for operation, the multiple access function of the content on the easy realization external memory card on many number of units code photo frame; Centralized management can should have certain characteristic of managing independently to the resource that fictionalizes; Under the standard of unified management, good interoperability between the realization system; Resource utilization is high, can realize simultaneously that many number of units code photo frame is to the read-write operation of external memory card.
