Technical field
The present invention is relevant with document copying, is meant a kind of method of massive duplication data especially.
Background technology
In some particular industries,, often need a large amount of document copyings in one or more a large amount of Storage Medias as PC manufacturer or hard disk manufacturing merchant.Therefore, the duplicator that can stablize and apace great mass of data is copied to one or more a large amount of storage bodies (as hard disk, flash memory etc.) is crucial.General duplicator has source joint chair and several purpose joint chairs.One source medium can be connected on this source joint chair, and each purpose joint chair can connect purpose medium, and duplicator can be with the document copying in this source medium to each purpose medium.
The invention of the system or the method for many announcement document copyings is formerly arranged in the skill, for example: United States Patent (USP) the 5th, 777, a kind of numerical data dubbing system that No. 811 patents disclose wherein mainly is that the data that will duplicate is sent into primary memory (being generally random access memory (RAM)) earlier and then data is write in another storage assembly.Such data transmission mode is reliably, but transmitting speed can be extracted instruction because of central processing unit, the read-write data computation is interfered.United States Patent (USP) the 6th, 131, No. 141 patent has disclosed a kind of hard-disk duplicator (hard diskdrives duplicator), its topmost feature is to utilize a control device, allow the data of source storage assembly directly reach the target storage assembly, can not be temporary in any impact damper (buffer) in the process of data transmission, reach the function of data high-speed transfer thus.U.S.'s patent of invention has also disclosed a kind of duplicator the 6th, 931, No. 459, and it mainly is to use first in first out, and (First In First Out, FIFO) internal memory is as the impact damper of data transmission.
Above invention all is to handle how the data in this source medium to be copied in each purpose medium fast and reliably.But when the practical operation duplicator, be earlier source medium and purpose medium to be contained in earlier on the joint chair of duplicator, duplicate then, after replication actions is finished, need all purpose medium are unloaded, and then load onto new purpose medium, to carry out replication actions next time.When changeing the purpose medium, whole dubbing system stops, and this is the subject matter that causes doubling time to prolong on the contrary.
Summary of the invention
At the problems referred to above, fundamental purpose of the present invention is to provide a kind of method of massive duplication data, and it can reduce the prolongation of the doubling time that is caused because of replacing purpose medium.
To achieve the above object of the invention, the method of a kind of massive duplication data provided by the present invention, its by a duplicator with the document copying of source in the data medium to a plurality of purpose medium, it is characterized in that including the following step: a) described source data medium and each described purpose medium are connected on the described duplicator; B) with the data in the data medium of described source in regular turn and circulation repeat to be sent to each described purpose medium; C) each described purpose medium receives and duplicates the data that is sent by described source data medium; D) check that whether the data in the data medium of described source is copied to each described purpose medium fully, in this way, then unloads and change new purpose medium, an execution in step c again with described purpose medium from described duplicator; As not, then continue execution in step c; Wherein in the process of changing arbitrary described purpose medium, remaining purpose medium still carries out replication actions independently, can't end because of changing the purpose medium.
In the technical scheme of the invention described above, the replacing time of each purpose medium is inequality.
In the above technical scheme of the present invention, whether the data in the data medium of described source checked is copied to each described purpose medium fully is: d1) respectively each described purpose medium is received for the first time the data record of sending here from described source data medium and be the comparison data; D2) whether received data is described comparison data after the comparison, in this way, then represents the data in the data medium of described source to be copied to described purpose medium fully.
In the above technical scheme of the present invention, each comparison data is the address of the data of the described reception first time of record, and whether the address of received data is identical with the address that described comparison data is write down after the comparison, as identical, then represent the data in the data medium of described source to be copied to described purpose medium fully.
In the above technical scheme of the present invention, also include a step and be: when being connected on the described duplicator, promptly stop to transmit the data in the data medium of described source without any the purpose medium.
In the above technical scheme of the present invention, also include a step and be: all finish when duplicating when all purpose medium, promptly stop to transmit the data in the data medium of described source.
Owing to adopted above technical scheme, the beginning of each purpose medium of the present invention is all inequality with the time that finishes to duplicate, and duplicate in the process of the purpose medium that more renew after the end, other purpose medium still continue to carry out replication actions independently, and the target medium of newly changing can enter at any point of broadcast material, and begins to duplicate.So can significantly shorten because of changing the prolongation of the doubling time that the purpose medium are caused, can satisfy PC manufacturer or hard disk manufacturing merchant needs the demand of a large amount of document copyings in one or more a large amount of Storage Medias.

Embodiment
For the effect that describes structure of the present invention in detail and reached, the existing act under following preferred embodiment and the conjunction with figs. explanation.
As shown in Figure 1, be the process flow diagram of the clone method that preferred embodiment of the present invention provided.Fig. 2 shows a duplicator 10, and it has source joint chair 12 and four purpose joint chairs 141～144, and source joint chair 12 can connect a source data medium 16, and each purpose joint chair 141～144 can connect purpose medium 181～184.Have central processing unit, internal memory and other associated component (not shown) in the duplicator 10, with the document copying in the future source material medium 16 to each purpose medium 181～184.Each medium can be flash memory (flashmemory card), hard disk (hard disk), floppy disk (floppy disk), CD (compact disk, CD), digital image and sound optical disk (DVD), or the storage assembly of other form.Each medium shown in the figure are the SD memory card.
As shown in Figure 2, user's source material medium 16 at first in the future is connected in source joint chair 12, then again one first purpose medium 181 is connected to purpose joint chair 141.After duplicator 10 detects purpose medium 141 and connects, promptly can be automatically the data in the source material medium 16 in the future, in the mode of similar broadcasting, in regular turn and circulation repeat to be sent to purpose medium 141.Suppose that there are 100 documents in the source in the data medium 16, duplicator 10 transmits since No. 1 data, be sent to No. 100 data after, accent is from No. 1 data transmission again.
The data logging that duplicator 10 can receive purpose medium 181 for the first time is a comparison data S1 (compare data S1 this moment is No. 1 data), and the corresponding address in purpose medium 181 writes data.Whether can and purpose medium 181 are when receiving the next record data, first comparison data identical with the data of comparison S1? as inequality, then the corresponding address in the purpose medium writes data.After supposing that the user is connected in purpose joint chair 142 with second purpose medium 182, duplicator 10 transmits No. 12 data.At this moment, as shown in Figure 3, the comparison data S2 that duplicator 10 can be purpose medium 182 with No. 12 data logging, and the corresponding address in purpose medium 182 writes data.According to identical step, after we suppose to connect the 3rd and the 4th purpose medium 183,184, duplicator 10 transmits No. 26 and No. 40 data, therefore, comparison data S3, S4 that duplicator 10 is two purpose medium 183,184 with the 26th, No. 40 data logging respectively, as shown in Figure 4, and this moment duplicator 10 just transmitting data No. 76.
Be noted that at this what compare respectively that data S1～S4 write down is the address of the data that receives for the first time.Because duplicator 10 be in proper order and circulation repeat to send data in the source material medium 16, therefore, address as received data and comparison data is identical, then is that represent this document promptly be the data that the receives first time, and just all data have all been duplicated and finished.Certainly, other can check whether the data in the data medium 16 of source is copied to the method for purpose medium fully, also is that the present invention is adoptable.
As shown in Figure 5, after duplicator 10 has transmitted No. 100 data, can transmit data once more No. 1.At this moment, it is identical with the comparison data S1 of the first purpose medium 181 that duplicator 10 can detect the data that is transmitted, all data in this representative source data medium 16 all have been copied to the first purpose medium 181, duplicator 10 can stop target joint chair 141 reception data, and send a signal, require the user to change new purpose medium 201.
As shown in Figure 6, suppose that it is No. 8 data that new purpose medium 201 insert the received the first stroke data in back, the address that this moment, S1 can write down No. 8 data.Then, when duplicator 10 transmits No. 12 data, can stop target joint chair 142 reception data, and send a signal, require the user to change new purpose medium 202.
Repeat identical action, can repeat,, change one by one at the preset time point with the purpose medium on each target joint chair.And in the process of changing a certain purpose medium, other purpose medium still continue to carry out replication actions independently.
Have the opportunity that clone method provided by the present invention stops two: one for when duplicator detect without any the purpose medium be connected on each target joint chair; Two for when all purpose medium finish duplicate after, the purpose medium that more do not renew.
In sum, when utilizing method provided by the present invention to duplicate, basically, the beginning of each purpose medium is all inequality with the time that finishes to duplicate, and duplicate in the process of the purpose medium that more renew after the end, other purpose medium still continue to carry out replication actions independently, and the target medium of newly changing can enter at any point of broadcast material, and begin to duplicate.So can significantly shorten the prolongation of the doubling time that is caused because of replacing purpose medium.
What propose to illustrate is: when the purpose medium began the data of receipt source data medium, suitable flow management was necessary, in order to avoid the speed of source medium transmission data is too fast, and made the purpose medium miss data.
