Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structured flowchart of the software backup system of present device terminal;
Fig. 2 is the software backup method flow diagram of present device terminal.
Embodiment
In order to make object of the present invention clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, in the structured flowchart of the software backup system of device end of the present invention, the external memory storage 20 comprising device end 10 and be connected with device end 10.This device end 10 comprises: microprocessor 11, and the input block 12, storage unit 13, interface unit 14, detecting unit 15, the creating unit 16 that are connected respectively with this microprocessor 11; This input block 12 is for receiving the input information of user; The input information that microprocessor 11 transmits for receiving input block 12, and judge that whether whether this input information consistent with the back-up validation stored in storage unit 13, if consistent, then device end 10 and external memory storage 20 connect, and are stored in external memory storage 20 by needing the software backed up in storage unit 13 by interface unit 14; Interface unit 14: be electrically connected with microprocessor 11 and be connected with external memory storage 20, for data transmission in device end 10 with external memory storage 20; Storage unit 13 is for needing software and the back-up validation of backup in memory device terminal; Whether detecting unit 15 is connected with external memory storage 20 for checkout equipment terminal 10, when detecting unit 15 detects external memory storage 20, device end 10 loads external memory storage 20, is stored in external memory storage 20 by needing the software backed up in storage unit 13 by interface unit 14; Creating unit 16 is for after device end 10 and external memory storage 20 connect, and in external memory storage, 20 create file.
In specific implementation process, the back-up validation stored in storage unit 13 can be numeral, letter, word etc., user inputs information by input block, microprocessor 11 judges that whether this input information is consistent with back-up validation, if consistent, then illustrate that user wishes the software backup in storage unit in external memory storage, if inconsistent, then do not perform backup, if do not receive the input information of user, then illustrate that user does not wish the software backup in storage unit in external memory storage.When this input information of microprocessor judges is consistent with back-up validation, external memory storage 20 whether is connected with again by detecting unit 15 checkout equipment terminal 10, if had, then device end 10 loads this external memory storage 20, the creating unit 16 of device end 10 externally creates file in storer 20, and the internal memory of the fixed size used is needed to device end 10 application, from 0 address of the storage unit of device end 10, follow the bad data that read is put in internal memory, the size of each reading is the same with the memory size of application, then data in EMS memory is written in the file of external memory storage 20, often write once, the reading address of storage unit 13 all to increase with writing address in file and also address identical, until read address exceeded the size of storage unit, then backed up.Because the size of the data in each reading cells can only be the same with the size of internal memory of applying in internal memory, so the data in the file of write external memory storage can not disposablely run through, need to read in batches, just can one-time write with the equirotal space of storage unit if can apply in internal memory.
In the present embodiment, external memory storage 20 can be portable hard drive or USB.
As shown in Figure 2, in the software backup method flow diagram of device end of the present invention, use the software backup system of device end as shown in Figure 1, comprise the following steps:
S1, device end 10 carry out initialization:
S2, device end 10 receive the input information of user by input block 12;
The microprocessor 11 of S3, device end 10 receives the input information of input block 12 transmission, and judges that whether whether this input information consistent with the back-up validation stored in the storage unit 13 of device end 10, if unanimously, then performs step S4, otherwise terminates;
S4, device end 10 connect with external memory storage 20, are stored in external memory storage by needing the software backed up in storage unit 13 by interface unit 14;
S5, end.
Further, above-mentioned steps S4 comprises the following steps:
Whether S41, device end 10 are connected with external memory storage 20 by detecting unit 15 checkout equipment terminal 10, if had, then perform step S42, otherwise perform step S5;
S42, device end 10 load external memory storage 20;
The creating unit 16 of S43, device end 10 externally creates file in storer 20, and needs the internal memory of the fixed size used to device end 10 application;
S44, follow the bad data that read be put in internal memory from 0 address of the storage unit 13 of device end 10, each size read is the same with the memory size of application, then data in EMS memory is written in the file of external memory storage 20; Often write once, the reading address of storage unit 13 all to increase with writing address in file and also address identical, until read address exceeded the size of storage unit, then backed up.Because the size of the data in each reading cells 13 can only be the same with the size of internal memory of applying in internal memory, so the data in the file of write external memory storage can not disposablely run through, need to read in batches, just can one-time write with the equirotal space of storage unit if can apply in internal memory.
In specific implementation process, storage unit is FLASH, and the back-up validation stored in storage unit can be numeral, letter, word etc., and this external memory storage 20 is portable hard drive or USB.
In this scenario, device end, when receiving input information (i.e. the backup request) of user by input block, is stored in external memory storage by needing the software backed up in storage unit by interface unit; Therefore, can conveniently will the software of backup be needed to be kept in external memory storage on the one hand; On the other hand, device for disassembling terminal can also be saved, deduct unnecessary trouble.Using this software backup method that user or developer can be avoided to obtain software to tear cost and the time of machine and welding open, the cost required for a cd-rom recorder can also be saved.If developer or manufacturer lose software or software does not back up, when terminal client not too specialty do not have terminal client can be allowed according to said method production software to be returned to developer or manufacturer when technical support.
Set Top Box for device end, one Set Top Box manufacturer finds that the set-top box software that oneself is produced to client has gone wrong, but the software appearing goods to client is no problem before, do not back up owing to producing software, or due to oneself have changed too many thing can not to reduce etc. a variety of causes have no idea to obtain before the software produced, terminal sale over there again for electronics aspect not too specialty can not provide software with cd-rom recorder etc., in order to can better save time and enhance productivity, client can be allowed to use said method by software backup out, the software being stored in external memory storage (as USB) is being supplied to manufacturer to guarantee timely production.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
