3rd, Bity is converted into integer Inty, Inty to 11 progress complementation computings, obtains remainder as check bit, made
For return value, X is returned when wherein remainder is 10.
S406. bar code parsing module parses the string content of bar code, by taking bar code SC1234567890X as an example, by bar code
First 12 are parsed into three parts, and its groundwork logic is as follows:
1st, the i.e. system banner position, and by finding corresponding system data library name in system mapping table of parsing bar code the 1st
Claim DataBase;
2nd, document classification is numbered in parsing bar code the 2nd i.e. system, and passes through the classification map in DataBase databases
Corresponding document data storage table name DataTable is found in table;
3rd, bar code the 3rd~12, i.e. document sequence FNum are parsed;
S407. file search module is according to system data library name DataBase, data table name DataTable and system
Interior document code FNum, is searched whether in the presence of the document object associated (i.e. into correspondence system:Into correspondence system database,
Search the data record whether in corresponding data table with correspondence document sequence number), if searched successfully, go to S408;Otherwise
Into S409;
The logic for searching associated with is as follows:
1st, the connection with database D ataBase is created;
2nd, in DataBase, corresponding data is searched in tables of data DataTable according to document sequence FNum and remembered
Record Record;
If the 3, searched successfully, the essential information (including document title, download link etc.) of document is searched in Record;
S408. document is traced to the source success, shows that the information of the document found simultaneously provides profile download service.
S409. document is traced to the source unsuccessfully, shows warning message.
It should be noted that " Quick Response Code " in description and claims of this specification and accompanying drawing can use various
Coding standard, it is preferable that Fig. 2 uses the Quick Response Code of QR standards in the present embodiment.In addition, term " comprising " and " having " with
And its any deformation, it is intended that covering is non-exclusive to be included, for example, containing the process of series of steps, it is not necessary to be confined to
Those steps clearly listed, but can include not listing clearly for these steps other intrinsic steps
