As shown in Figure 1, the endowed method of multi-packaging of the complement code error correction described in one embodiment of the invention comprises the steps:
Step 1, in the code spraying system that the first order is packed on process for producing line, code generator is each first order packaging generation unique code, is dealt into ink jet numbering machine and stored in the incidence relation table in endowed device database, waits for the relation that is associated.
Step 2, process for producing line comprise in the endowed system of second level packaging of one group of first order packaging, generate collection picture, the picture that the analysis of code Acquisition Processor gathers after gathering the code of the upper spray printing of this group first order packaging of collected by camera, generate a group code and be sent to endowed device.
Step 3, endowed device generates the code wanting spray printing to pack to the second level, be dealt into ink jet numbering machine and the relation that is associated with the code that the current second level is packed by the code of this group first order packaging collected, compared by the code collected in this group code and database in incidence relation table, the consistent code of comparison result carries out update of incidence relation in incidence relation table.
Step 4, in the code that in this group code collected, it fails to match is stored into that it fails to match record sheet.The storage content of it fails to match record sheet should comprise the index position of code, source picture and the source picture that it fails to match, the information such as the acquisition time of source picture can also be comprised.
Step 5, if production line also comprises the process of next stage packaging, then repeats step 2 to step 4.
Step 6, after production line completes predetermined production task, reads the content that stores in it fails to match record sheet and carries out complementary matching process.Complementary matching process specifically comprises the steps:
Step 61, to read in it fails to match record sheet each yard of corresponding picture, again carries out exposure calculation, again obtain the code information of photo current, if again expose the code information completely of generation, and the directly incidence relation of this yard in renewal incidence relation table.
Step 62, if code can't supplement complete by exposure again, then according to the character of inferring defect with case principle from this group code, code can be divided into some sections, in gathered this group code corresponding with current secondary package, extract the code gathering infull code complete with collection and compare, obtain defect character, defect character in code is supplemented complete, upgrades incidence relation table.Because the length of spray printing unique code is on the packaging fixing, such as 8 bit codes originally, only may collect several wherein, but the particular location of one or more characters in code lacked can be determined, again because all codes are all by unified generate rule, each code comprises fixing and not fixed character, such as comprise the date, title, the information such as serial number, so in secondary package these level packages code in the date normally identical, serial number generates continuously, so code can be divided into some sections according to information type, such as identical according to the character in date section, ultimate character in serial number section is continuous print, as long as therefore determine the particular location at the character place of defect in the code that it fails to match, namely defect character can be extrapolated by the character on the corresponding position of full code in this group code.
Step 63, after step 61 and step 62 complete complement code, if also residue has the code that it fails to match in it fails to match record sheet, may be transfer due to task in process of production to checked first order packaging, the first order packaging causing transferring has departed from order during coding, at this moment, the remaining code that it fails to match can be mated with the code in incidence relation table, obtain and the immediate group code of the remaining code that it fails to match, the character of defect in the code that it fails to match can be inferred from this group code according to same case principle, complete complement code, upgrade the incidence relation of incidence relation table.
Wherein, step 61 and step 62 can exchange sequences.
