Description

It is a kind of based on method of the USB flash disk to embedded product write sequence number
Technical field
The present invention relates to band USB flash disk mouth embedded product, and in particular to it is a kind of based on USB flash disk to embedded product write sequence number Method.
Background technology
In various embedded type household electric appliances, the Shi Douhui that dispatches from the factory writes a unique identifier sequence number to product, with side Just manufacturer's shipping management, sales management and after-sales service management；For purposes of illustration only, the instrument of write sequence number is known as the number of writing System, in conventional art, most of embedded products can additionally stay a serial interface, utilize serial communication to coordinate the number of writing system Complete write sequence number, whole process includes serial ports handshaking information, data sending, response message etc., which add hardware into Sheet and cost of labor.
The content of the invention
The technical problems to be solved by the invention are：It is proposed it is a kind of based on method of the USB flash disk to embedded product write sequence number, Solve to need to reserve the increase hardware that serial interface carrys out the mode of write sequence number and bring exclusively for embedded product in conventional art The problem of cost and cost of labor.
The present invention solves the technical solution that above-mentioned technical problem uses：
It is a kind of based on method of the USB flash disk to embedded product write sequence number, comprise the following steps：
A. configuration file and sequence number file are placed in USB flash disk；
B. after embedded product opening initialization USB flash disk and carry, the configuration file in USB flash disk is obtained；
C. analysis configuration file obtains needing the data amount check of write-in embedded product and corresponding filename；
D. corresponding document name is found in USB flash disk, data content is read and is written in embedded product.
As further optimization, the embedded product is set-top box.
Optimize as further, in step a, the filename and structure of configuration file and the sequence number file are by set-top box Software definition.
Optimize as further, in step a, confidence is matched somebody with somebody in the storage that the structure and set-top box software of the configuration file define The structure of breath is consistent, including header, length, entry number, entry name character string and end mark.
As further optimization, in step a, storage sequence that the structure and set-top box software of the sequence number file define The structure of number information is consistent, including the length of header, significant character, sequence number number, starts sequence number, current sequence Number, write number and end mark.
Optimize as further, in step b, be stored in after obtaining the configuration file in USB flash disk in set-top box memory buf.
Optimize as further, in step c, the analysis configuration file specifically includes：Configuration file structure content is assigned It is worth the structure of the storage configuration information defined to set-top box, analysis structure gets the sequence number item of write-in set-top box.
Optimize as further, in step d, the corresponding document name that found in USB flash disk specifically includes：
The corresponding sequence number file of sequence number item got from USB flash disk reading, in sequence number file after reading successfully Hold the structure for being assigned to the storage sequence number information that set-top box defines.
As further optimization, in step d, the reading data content and writing in set-top box specifically includes：
Set-top box gets the structure content of storage sequence number information, current sequence number writing machine top in structure Current sequence number in structure, after writing successfully, is added 1, has write number and added 1 by box, and writes back the sequence number file in USB flash disk.
The beneficial effects of the invention are as follows：Using the existing USB interface of hardware itself, pass through custom profile name and text Part structure, realizes that write-in content can configure, and reads corresponding document according to configuration content, obtains valid data and write embedded production Product；The hardware cost of extra increase serial ports can be reduced, reduces cost of labor, the more simple and reliable words of production procedure, and reduce and sell The complexity repaired afterwards.
Brief description of the drawings
Fig. 1 is based on method flow diagram of the USB flash disk to embedded product write sequence number in embodiment.
Embodiment
The present invention is directed to propose it is a kind of based on method of the USB flash disk to embedded product write sequence number, solve to need in conventional art Serial interface is reserved exclusively for embedded product and comes increase hardware cost that the mode of write sequence number brings and cost of labor Problem.
In the present invention based on method of the USB flash disk to embedded product write sequence number, comprise the following steps：
A. configuration file and sequence number file are placed in USB flash disk；
B. after embedded product opening initialization USB flash disk and carry, the configuration file in USB flash disk is obtained；
C. analysis configuration file obtains needing the data amount check of write-in embedded product and corresponding filename；
D. corresponding document name is found in USB flash disk, data content is read and is written in embedded product.
Embodiment：
By taking the method flow of write sequence number into set-top box as an example, as shown in Figure 1, it includes implemented below step：
1.U packing catalogues put configuration file " SystemInfoConfig.dat ", we are known as file A；File structure is determined Justice is：Head (systeminfoconfig)+length+entry number (1)+entry name character string (serial)+end mark end] }；
2.U packing catalogues put serial.bin files, we claim file B.Document structure definition is：Head (serial)+long Degree (length of significant character)+sequence number number+beginning sequence number+current sequence number+has write number+end mark (end])；
3. set-top box software defines 2 structures, a storage configuration file A structure content, we claim this structure For StructA, another storage sequence number file B structure content, our this structure is referred to as StructB；Wherein StructA Structure be：
Char confighead [20] // configuration file header
U8Length//significant character length
U8Item//write-in set-top box item number
Char dataname [10] [the 20] // corresponding filename of write-in each data of set-top box
Char endbuf [4] // end mark END] }
The structure of StructB is：
Char datahead [20] // machine File header information
U8Length//significant character length
U8SerialNumber//sequence number number
Char FirstSN//beginning sequence number
Char CurrentSN//current sequence number
U8finshNumber//write number
Char endbuf [4] // end mark
4. after set-top-box opening initialization USB flash disk mouth and carry, going to read configuration file, read failure box and normally start, After reading successfully, configuration file A structure contents are assigned to the structure StructA defined in third step, analysis structure obtains Get the sequence number item of write-in set-top box；
5. reading the sequence number item serial.bin files got in the 4th step from USB flash disk, read failure box and normally open It is dynamic, the content in file B is assigned to StructB structures after reading successfully.
6. set-top box gets structure StructB contents, current sequence number write-in set-top box in structure；
7. after writing successfully, the current sequence number in StructB structures is added 1, number is write and has added 1, and write back in USB flash disk Serial.bin files.After writing successfully, turn off file A and file B.
