embodiment mono-
Fig. 1 shows the first realization flow of the file wiring method that the embodiment of the present invention one provides, and for convenience of explanation, only shows part related to the present invention.
In the present embodiment, described method is applied to wireless memory apparatus, described wireless memory apparatus for by the file of intelligent terminal by wireless network transmissions to storage medium.Wherein, described wireless memory apparatus comprises mixed-media network modules mixed-media and the interface that is connected storage medium.Described mixed-media network modules mixed-media is preferably Wi-Fi module or bluetooth module, the interface of described connection storage medium is preferably one or several in USB interface, Micro USB interface, SD interface, MicroSD interface, and described storage medium is the external storage mediums such as USB flash disk, SD card.Described wireless memory apparatus also can only include mixed-media network modules mixed-media and built-in storage medium, by the shift knob on wireless memory apparatus shell, realizes access or extracts built-in storage medium.
As shown in Figure 1, described method comprises:
In step S101, the writing after order of network file packet being detected, timing time is set and starts timing.
The present embodiment arranges an overall cache timer in wireless memory apparatus.Described cache timer can be realized by software, also can realize by the timer of a hardware.At this, the implementation of timer is not limited.At the initial stage starting at wireless memory apparatus, detect a network file packet and write after order, and the state that timer is set is default timing time, and starts timing.
In step S102, according to said write order, described network file packet is written in the cache of described wireless memory apparatus.
In the present embodiment, described cache is file system cache.Exemplary, described cache is for the buffer zone (SDRAM) of storing documents in wireless memory apparatus.
At the initial stage starting at wireless memory apparatus, detect a network file packet and write after order, and the state that timer is set is default timing time, starts timing, network file packet is written in file system cache simultaneously; Or, writing after order of network file packet detected, described network file packet is written in the file system cache of described wireless memory apparatus, the state that then timer is set is default timing time, starts timing.
The timing time of described timer is to arrange according to the performance of embedded hardware equipment and network schemer optimization.Because different users' reaction velocity is different, swift user can extract rapidly storage medium after seeing network file end of transmission.Therefore, timing time is arbitrary value in 1 millisecond to 100 milliseconds, is preferably arbitrary value in 1 millisecond to 10 milliseconds.It should be noted that, the time that described single network file data bag is written to cache is very short, be less than timing time, so this programme " is not written to described network file packet in the cache of described wireless memory apparatus " step and the sequencing of step " state that timer is set is timing time, and starts timing " limits.Described timing time is less than user and sees the complete reaction time to extracting storage medium of file transfer.
In step S103, if the order that writes of next network file packet do not detected in described timing range, the All Files data in described cache are written to storage medium.
In the present embodiment, the timing time that is provided with timer rises, and the mode that timer starts to increase progressively or successively decrease starts timing, until reach timing time or timing time, is decremented to zero, and this process all belongs to timing range.The order that writes of next network file packet in timing range, do not detected again, characterize and do not have other new network files to need transmission.Now, after timing time arrives, timer timing finishes, and timeing closing device no longer receives the action of next timer, and the All Files data in described cache are written in storage medium.It should be noted that, the file data in cache or reached critical value now, or not yet reach critical value, but after timeing closing device, the All Files data in cache are written in storage medium without exception.
Further, described method also comprises:
In step S104, if in described timing range, the order that writes of next network file packet detected, the timing time of resetting carries out next round timing; According to said write order, described next network file packet is write in described cache.
Further, when carrying out described step S103, also comprise: the mode of operation according to cache is written to storage medium by file data.
The described step that file data is written to storage medium according to the mode of operation of cache is specially:
Whether the file data detecting in described cache reaches critical value; If so, the critical value in described cache is write in storage medium with interior All Files packet;
Otherwise, do not carry out write operation.
Described critical value is the size of or several bunches.Exemplary, when writing the file data of cache, reaching after critical value, cache will write storage medium with interior file data by critical value.Suppose that this critical value is 64KB, the original state in cache is 0KB, and the network file packet that writes for the first time cache is 50KB, and now, the file data detecting in cache does not reach critical value, does not carry out write operation.In timing range, receive second network file packet, size is 20KB.Described second network file packet is written to cache, while writing 14KB, the file data detecting in cache has reached critical value, critical value is written to storage medium with the file data of interior (being the 50KB of first network file packet and the 14KB of second network file packet), the 6KB file data of second network file packet is retained in cache, until the file data of cache storage reaches after critical value, then write storage medium.Certainly, if next network file packet do not detected in timing range,, after timing, the 6KB file data of second network file packet is also written to storage medium, and do not need to reach critical value, does not write again.
By above-mentioned steps, when the wireless transmission of carrying out between intelligent terminal and storage medium, by a timer is set in wireless memory apparatus, receive writing after order of a network file packet, the timing time of timer is set, start timing.If do not receive the order that writes of next network file packet in timing time, wireless memory apparatus is written to the All Files packet in cache in storage medium.Because being less than user, described timing time sees the complete reaction time to extracting storage medium of file transfer, therefore, after file transfer, user is from eye recognition to extracting the process of storage medium, wireless memory apparatus is written to storage medium and preserves being temporarily stored in file data in cache, obliterated data while having prevented that user from extracting storage medium from wireless memory apparatus.
Further, owing to carrying out file in batches while writing task, the interval that writes instruction is normally below 1ms, 800 microseconds for example, and it is much smaller than default time value.Network file packet writes the time of cache also much smaller than timing time.Therefore when inputting network file continuously, in timing time, be bound to detect the order that writes of next network file packet, the timing time of timer of resetting carries out next round timing, file data in cache reaches critical value or timer timing finishes, just the file data in cache is written to storage medium, thereby solved prior art because triggering timer is continually written to the file data in cache the low problem of write efficiency causing in storage medium, improved the efficiency writing.
Described in the present embodiment, method only need to arrange a timer in wireless memory apparatus, does not need wireless storage client to modify, and is applicable to any Web, Android App, iOSApp, Mac etc.Said write method is automatically written to the network file packet in cache in storage medium after timer arrives default timing time, user does not need manually to go to click unload button, solved due to the problem of forgetting the loss of data that click unload button causes, promoted user's experience.
