and S208, during delivery, the outer package code is collected through the data collector and is bound with the information of a receiving unit.
Specifically, the data acquisition unit can use PDA equipment, and by the method, the dealer information can be reversely inquired through any level of coding information in the market, so that the tracing management of the flow direction is realized; during practical application, information of dealers at all levels is collected in a selling link, so that a complete data chain is formed in the whole circulation link, and the selling link can be conveniently checked by a supervision department.
When the method is applied, two sending modes of the coding information are included, the two application modes are mainly because the method is limited by a cache mode of the coding equipment, and part of the coding equipment does not support cache, so that data information needs to be sent every time (rule 1), and part of the coding equipment can support cache data, so that part of data can be sent to the coding equipment in advance, and the real-time communication cost between the equipment is reduced (rule 2).
Rule 1: the method has the advantages of single data transmission, small data influence range when equipment is abnormal, and no influence on later data. The disadvantage is that the communication cost between the devices is high due to the network environment of single communication.
Rule 2: the method has the advantages that data caching is supported, data can be sent in advance, and communication cost between devices can be effectively saved by consuming a supplement mode. The method has the disadvantages that the pre-sent data can be discarded once the equipment is abnormal, and the processing needs to be performed through manual intervention in time.
rule 2 is as follows:
furthermore, in order to ensure the normal operation of the subsequent steps and the accuracy of the data queue when the production line is abnormal, when the abnormal condition occurs, the plus-minus queue device arranged on the production line is used for adding or subtracting one to the data queue to be associated.
Specifically, referring to fig. 3 and 4, in the production process, when a primary product package is damaged, and an abnormal product is rejected by a detection device, the primary product is rejected and manually rechecked, which may cause a situation that a real object is taken off from a production line and a data queue still exists, in order to ensure that the situation can be handled in time, the influence on the whole queue of the to-be-associated data is reduced, which may cause a situation that the deviation between time synchronization data and the real object is enlarged, by deploying an add-subtract queue device, the primary product code to-be-associated queue of the decrement button is reduced by 1 every time the decrement button is pressed, and the primary product code to-be-associated queue of the increment button is increased by 1 every time the decrement button is pressed (the add-subtract number may be preset and adjusted according to the characteristics of the production line), so that the normal operation of the production line is not affected.
Further, in order to improve the accuracy of the data queue association, the method further comprises:
and carrying out time synchronization verification, respectively obtaining the code assigning time on two adjacent stages of products through a data acquisition unit, verifying according to a preset verification rule to obtain a verification result, and displaying the verification result through the data acquisition unit, wherein the verification result comprises passing verification and failure verification.
Specifically, referring to fig. 5, the preset validation rule is that the code assigning time on two adjacent stages of products cannot exceed 60 seconds, for example: verifying the operation steps (taking a first-level product bag and a second-level product box as examples): when the large box code is scanned and the bag code is scanned, the terminal interface displays the verification result (pass or fail) and simultaneously displays the time difference range (unit: second) between the box code time and the bag code.
The verification result judgment logic is as follows:
the bag code time passes the verification within 60 seconds of the upper and lower limits of the box code association time, and the bag code time fails when the bag code time exceeds the 60 second range. Correct start time period range definition (first bag time minus 60 seconds, last bag time plus 60 seconds in current bin code), for example: the box code associated bag code first code time is 20180601110000, the tail code time is 20180601113000, the verified bag code time is in the range of 20180601105900 to 20180601113100, the verification is passed if the time range is exceeded, more than half of the bag code time in the box and the box code time are synchronously verified to pass, and the synchronization is successful.
Referring to fig. 6 and 7, in order to correct the queue in time after the verification anomaly is found, so as to ensure the synchronization accuracy of the subsequent data and the real object, when the verification result is a verification failure, a one-key correction operation is performed by the data collector, where the one-key correction operation has the following steps:
when the code assigning time of the upper-level product is earlier than that of the lower-level product, adding a data queue to be associated of the upper-level product;
and when the code assigning time of the upper-level product is later than that of the lower-level product, reducing the data queue to be associated of the upper-level product.
Furthermore, in order to timely find possible abnormalities of the coding equipment in the production process, if the possible abnormalities cannot be found in time, large-area data abnormalities or hidden dangers of product quality may be caused, and therefore monitoring is needed; the method further comprises the following steps:
the early warning equipment automatically clears the early warning after timely early warning according to a set value;
specifically, the alarm is timed according to a preset timing interval (namely a set value), for example, the sound and light alarm is kept for 5 seconds every time, the alarm is automatically cleared after 5 seconds (the time can be configured and set according to actual conditions), and an operator is regularly reminded to perform verification operation.
The production line system sets the upper buffer limit and the lower buffer limit according to the current production line rule, and when the upper buffer limit and the lower buffer limit exceed the upper buffer limit and the lower buffer limit, the early warning equipment is triggered to give an alarm.
Specifically, each production line product cache has a certain rule, the upper limit and the lower limit of the cache are set according to the current production line rule, the system triggers the early warning device to give an alarm when the upper limit and the lower limit are exceeded, and an operator manually clicks the reset switch to reset the alarm after checking and processing abnormal problems.
Further, in order to facilitate the retrospective query of the product market flow direction, the method further includes that the data collector scans a plurality of products to be queried as samples, the number of the samples is greater than or equal to five, and the interval time between every two samples is fifteen minutes.
Further, as the production line equipment is more, each fault node may affect data synchronization, so that abnormal nodes are summarized according to the characteristics of different production lines and a preprocessing scheme is given, the feasibility of the overall scheme and the accuracy of data are ensured, and corresponding preprocessing schemes are formed for different abnormal conditions, and the following table is specifically referred to:
finally, it should be noted that the above description is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
