Abstract
An outside connected memory device and method can load on a portable digital device for data storing to the memory in continuous application of the device. When the control module identifies the portable digital device, it detects the left capacity of the buffer memory of the storage card, and writes data to the outer connected memory when the buffer space exceeds to avoid the stop of data activity due to small capacity of the memory card of the equipment.
Description
[Ji Intraoperative field]
Relevant a kind of external memorizer system of the present invention and method, particularly a kind of external memorizer system and method that when using portable digital equipment continuously, data is deposited in this external memorizer.
[Bei Jing Ji Intraoperative]
Now, portable digital equipment (as digital video camera DV, digital camera DC etc.) is extensively used by popular, and the data of the required storage of these portable digital equipments are quite big, when the user uses these equipment, the off-capacity of Chang Yinqi storage card, or memory card capacity is saturated and cause the situation be forced to end of using, and it needs computing machine to carry out data transmission as media, download data to another bigger data access arrangement, and then cause user's inconvenience; Though and have at present external memorizer can assist the capacity of its internal memory card of expansion, but must under the situation of this portable digital equipment shutdown, take out storage card, and then connect another external memorizer and data are read in wherein, cause like this to use and interrupt, also inconvenience is used.
[summary of the invention]
The object of the present invention is to provide a kind of external memorizer system and method, it can be stored in data on this external memorizer under the situation of uninterrupted use one portable digital equipment.
For reaching above purpose, the invention provides a kind of external memorizer system, comprise a portable digital equipment and an external memorizer, wherein, this external memorizer is provided with the control panel that is used to receive the default that the user chooses or import, and is used to discern the control module of the device that this external memorizer loads.
Again, the control panel communication of this portable digital equipment and above-mentioned external memorizer, and this portable digital equipment is provided with the central processing unit of the raw data that is used to handle the input port acquisition, and in order to the storage card of the data after temporary the processing.
External memorizer method of the present invention, this method comprises: whether (1) control module inquiry external memorizer loads on a portable digital equipment; If not, then repeat this step; If then enter (2) control panel inquiry control module and whether carry out storage operation; If not, then repeat this step, if then enter (3) control panel detecting storing card data and whether overflow; If, then enter (4) data and write storage card, if not, then enter (5) data and deposit external memorizer in.
After above-mentioned flow process, portable digital equipment is in running, its data sync storage in the direct communication of this portable digital equipment in external memorizer, thereby avoid this portable digital equipment because of self with the capacity too small activity that stops ongoing extracting data of storage card.
Relevant detailed content of the present invention and technology, conjunction with figs. is described as follows:
[description of drawings]
Fig. 1 is the composition block scheme of external memorizer system of the present invention.
Fig. 2 is the signal flow graph of external memorizer method.
[embodiment]
Please refer to shown in Figure 1, shown among this figure is the composition block scheme of external memorizer system, comprise a portable digital equipment 11 and an external memorizer 12 in this system, wherein, this external memorizer 12 is provided with a control panel 122, be used to receive the default that the user chooses or imports, for example can click the storage operation in the mode of operation that the control module 121 of this external memorizer 12 supported, this control module 121 is after the device that this external memorizer 12 of identification is loaded is a portable digital equipment 11, the residual capacity of the spatial cache of detecting portable digital equipment 11, and when data are overflowed this spatial cache, (Hard Disk Drive, HDD) 120 are used to store these data to hard disk drive.
Again, this portable digital equipment 11 is set up communication channel by USB (universal serial bus) 113 and the control panel 122 of stating external memorizer 12, and this portable digital equipment 11 is provided with a central processing unit 110, this central processing unit 110 is used to handle the raw data of input port acquisition, and the data transmission after will handling is given storage card 111, this storage card 111 is set certain spatial cache in total storage space, for example 1/2 or 1/3 of these storage card 111 total storage spaces, in order to the temporary back data of handling, and when data are overflowed this spatial cache, data are write external memorizer 12 by USB (universal serial bus) 113.
Please refer to Fig. 2, signal flow graph for external memorizer method of the present invention, at first, execution in step 210, whether control module 121 inquiry external memorizers 12 load on a portable digital equipment 11, be whether control panel 122 sets up communication channel with the USB (universal serial bus) 113 of portable digital equipment 11, if not, then repeated execution of steps 210, if, then execution in step 220, whether control panel 122 inquiry control modules 121 carry out storage operation, and if not, then repeated execution of steps 220, if, then execution in step 230, and control module 121 sends a detection signal, and whether detecting storage card 111 data have overflowed the spatial cache of setting, if not, then execution in step 240, and central processing unit 110 writes storage card 111 with data, if, then execution in step 250, and data deposit hard disk drive 120 in.
Therefore, according to external memorizer system provided by the present invention and method, can be under the situation of uninterrupted use one portable digital equipment, deposit data in an external memorizer, thus avoid this portable digital equipment because of self with the too small activity that stops ongoing extracting data of capacity of storage card.
