Description

Commodity traceability association method and system based on one-object-one-code
Technical Field
The invention relates to the technical field of internet, in particular to a commodity source tracing correlation method and system based on one object and one code.
Background
In the existing commodity tracing process, because the packaging and transfer reasons are mostly two-level or multi-level packaging, such as cans (bags), boxes and big boxes … …, the packaging of different levels need to be strictly correlated, and the tracing accuracy can be ensured. The basis of the association is to attach codes to the single products and packages of the commodities, and then the association is completed in a database through code scanning of the packages and the transportation links.
In the traceability code scanning link, most enterprises adopt a mode that a code scanning device is additionally arranged on a commodity production pipeline or a production line with the code scanning device is directly built. Each traced commodity is scanned by a code scanning device on a production line, box codes are scanned in the boxing process, and then the commodity codes and the box codes are correspondingly bound in a database (namely, one box code has to have a strict corresponding relation with the commodity codes in the box, and the box cannot be misplaced). Such an approach imposes strict requirements on the code scanning equipment of the production line and workers on the production line, and even then, the problems of missing scanning, scanning errors or misplacement still exist. This method is not efficient, and it is not cost effective for enterprises to add cost to the production line.

Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
the first embodiment is as follows:
as shown in fig. 1, a commodity tracing association method based on one object and one code of the present invention includes the following steps:
step S101: the set A is used for representing all the single products of the same variety produced on the same day, and the sequence of each element in the set A is the sequence of generating the single products; and generating single item codes for the single items according to the coding rule, wherein the single item codes are assigned to different single items according to the sequence of single item generation.
Step S102: packing the single products produced on the same day in the order of single product generation, and using the set WaShowing the packed items as set A1、A2、…、AmEach case of single article, denoted by WAA collection of presentation boxes; and generating box codes for the boxes, associating the single item codes and the box codes of all the single items produced on the same day by scanning the single item code of the first single item, the box code of the first single item, the single item code of the last single item and the box code of the last single item produced on the same day, recording the box packing time and uploading the box packing time to a tracing source database.
Step S103: a is to be1、A2、…、AmRandomly combined for shipment to form a collection WiW is as describediIncluding logistics information.
Example two:
as shown in fig. 2, another commodity tracing association method based on one object and one code of the present invention includes the following steps:
step S201: the set A is used for representing all the single products of the same variety produced on the same day, and the sequence of each element in the set A is the sequence of generating the single products; generating single item codes for the single items according to a coding rule, wherein the single item codes are assigned to different single items according to the sequence of single item generation; the coding rule is that the user code, the variety code, the batch code and the random code are sequentially combined to be used as a single product code.
Specifically, the total number of the single products of the same variety produced on the same day is n, and the total number is expressed by a set:
A={a1,a2,......,an}
the code attached to each single product is a random single product code with a fixed bit number of 53 bits generated according to a coding rule, and the single product codes are assigned to different single products according to the generation sequence and ensure one product to one code. The coding rule is that 12 bits of user codes, 13 bits of variety codes, 10 bits of batch codes and 18 bits of random codes are sequentially combined to form single product codes.
As one implementation mode, the single product code is an RFID code, an NFC code or a two-dimensional code.
Step S202: packing the single products produced on the same day in the order of single product generation, and using the set WaShowing the packed items as set A1、A2、…、AmEach case of single article, denoted by WAA collection of presentation boxes; generating box codes for boxes, associating the single product codes and the box codes of all the single products produced on the same day by scanning the single product code of the first single product, the box code of the first single product, the single product code of the last single product and the box code of the last single product produced on the same day, recording the box packing time and uploading to a tracing source database; generating a bin code for the bin includes: and sequentially forming a box code according to the user code, the batch code, the random code and the production time code.
Specifically, the single products produced on the same day are boxed into m boxes, each box is k single products, namely m = n mod k, the remainder is x, the remainder is not boxed, and the set of boxed products is Wa
Wa={a1,a2,......,akm}
The box code attached to each box set is a random box code with a fixed number of 23 bits, and one object is guaranteed to be one code. The generation mode of the box code is as follows: and the box code is formed by combining 12 bits of the user code, 10 bits of the batch code and 10 bits of the random code in sequence. As one possible implementation mode, the box code is an RFID code, an NFC code or a two-dimensional code.
The boxes are sequentially packed in the order of the production line, each box also being a collection. To differentiate the representation of sets, a1In (1) represents A1First item of box, a2In (2) represents A1The second individual item of the box, and so on, i.e. the collection of boxes is represented as follows:
A1={a1,a2,......,ak}
A2={ak+1,ak+2,......,a2k}
......
Am={a(m-1)k+1,a(m-1)k+2,......,amk}
WA={A1,A2,......,Am}
WA=Wa
because of the boxing process of the production line, sequential boxing is guaranteed according to the principle of first-out and first-in packing.
Ai、AjIs a subset of W, Ai∩Aj=∅(1≤i、j≤m;i≠j)。
After the production task on the same day is finished, the single product code and the box code produced on the same day are associated in a default mode by scanning the single product code of the first single product, the box code of the first box single product, the single product code of the last single product and the box code of the last box single product, and meanwhile, the box packing time is recorded and uploaded to a database.
After the single product is produced on the production line, the single product is required to be loaded into a plurality of different boxes, the box code of the first box is scanned by scanning the single product code of the first single product, and the single product code of the last single product and the box code of the last box are scanned when the production line finishes the production task on the same day. This operation obtains the first item code and the last item code, the first bin code and the last bin code, because the first and last are attached in sequence in the link of attaching codes, the first and last are scanned, and the system defaults to putting all items in this interval into these bins for association.
Different from the traditional method for scanning codes one by one in the production line, the invention relates the codes in a set mode through simple head and tail 4 times of code scanning actions.
Step S203: a is to be1、A2、…、AmRandomly combined for shipment to form a collection WiW is as describediIncluding logistics information.
Specifically, the manufacturer is in the process of shipping, A1--Am(random combinatorial delivery) to form a new set Wi(including logistics information):
W1={A11,A12,......,A1k1}
W2={A21,A22,......,A2k2}
......
Wg={Ag1,Ag2,......,Agkg}
Ww={W1,W2,......Wg}
A11in (1), the subscript 11 represents W1First box of set, A12In (1), the subscript 12 represents W1The second box of the set, and so on, the boxes of each set are not fixed, and k1, k2, and.
Aij∈W( 1≤i≤g,1≤j≤ki,k1+k2+k3+......kg=m)
W=W1∪W2∪......∪Wg
W={W1,W2,......,Wg}
Wi∩Wj=∅ (1≤i、j≤g;i≠j)。
In particular, WiBy passing through a stream in HiGround-borne transfer:
Wi={Ai1,Ai2,......,Aiki}
transshipment similar to factory shipment, WiThe bin reassembly in (1) into a new set is as follows:
Wi={Wi1,Wi2,......,Wit}(1≤t≤ki)
through the stream to Hij And ground (1 is less than or equal to j and less than or equal to t).
Step S204: scanning the single product code of the single product through a self-service scanning terminal to perform self-service scanning checkout on the single product, and generating a two-dimensional code with bill information;
or the sales terminal scans the single item code of the single item to check out.
As an implementable mode, the self-service scanning terminal is a mobile phone or a tablet, and the sales terminal is a cash register terminal.
Because electronic payment has high popularity, code scanning payment is realized through third-party tools such as WeChat payment treasures and the like, and self-service scanning checkout windows are also arranged in many supermarkets.
Specifically, after a customer enters a store, the two-dimensional code of the store is scanned through a mobile phone, the customer enters a small program of the store (the small program is communicated with a tracing platform through an interface), the price of a commodity is priced according to a variety code contained in a code, the variety code is provided for a seller by a manufacturer, and the seller binds the price and the variety code through background software connected with the small program of the store and writes the price and the variety code into a tracing source database.
Specifically, a customer scans the single item code of a commodity through a store applet scanning function to inquire the basic information of the commodity, the customer can enter a shopping cart to wait for settlement through the system after satisfaction, the commodity selected by the customer is divided into a single item code and a no single item, all commodities can be settled uniformly through the store applet, and all data enter a statistical system after settlement. Wherein, the commodities without single item codes only enter the statistical system to wait for the checkout at the outlet; and (4) storing the payment data of the commodities with the single commodity codes into a tracing database for tracing the commodities except for waiting for the detection of leaving the store.
Specifically, when a customer purchases a commodity single item in a shop or a supermarket, the cashier scans through a sales terminal to obtain a single item code, the price of the commodity is priced according to the variety code contained in the single item code, the variety code is provided to a seller by a manufacturer, and the seller binds the price and the commodity variety in advance through self cashier terminal software.
Step S205: after settlement, automatically uploading the sale time and the sale place corresponding to the single product to a tracing source database, inquiring the packing time and the batch of the single product by the tracing source database through the single product code of the single product, and comparing the tracing source database to obtain a set W where the single product is locatedaAccording to WaObtaining the collection W of the box where the single article belongsAThrough WAFinding a set W of all cases to a point of saleiAccording to WAPacking sequence arrangement W of middle boxesiThe tank (1).
Specifically, the single article a is checked out through the scanning checkout processsSales time and sales location communicationAutomatically uploading the data to a tracing database through terminal software, and enabling the tracing database to pass through a single product asThe single item code inquires the boxing time and the batch, and the single item a is obtained by comparing the tracing source databasesIn the set W, obtaining a single product a through WsSet W to which the box belongsAThen through WAFind-to-reach HijSet W of all bins of groundijAccording to WAThe packing sequence of the middle boxes is arranged in sequence WijThe tank (1).
Wij={Ar1,Ar2,......,Arq}
as∈W={a1,a2,......,akm}
Step S206: performing secondary boxing on the single product, wherein the secondary boxing comprises: restoring the single products to W according to the uploading sequence of the selling time and the selling placeiThe tank (1).
Specifically, for self-service scanning checkout, a customer scans a single commodity code of a commodity through a mobile phone terminal to carry out instant payment, checkout data of the commodity is automatically uploaded to a tracing source database, the checkout data of the commodity comprises basic information and sales time of the customer, meanwhile, a sales place and seller data are extracted from a small store program and uploaded to the tracing source database, the customer can inquire boxing time, batch and sales place of the single commodity through the single commodity code, secondary boxing is carried out by comparing the tracing source database, and continuous boxing is carried out on the single commodity of the same kind in the same time batch according to the sequence of customer checkout. The process is similar to counter sales, and the logistics information of the box in which the single goods are packed is restored and fed back to the client, and the client can scan the goods single goods code through the mobile phone to further check the goods single goods code.
Specifically, for the scanning checkout through the sales terminal, the single products are packaged in boxes for the second time after scanning, and are restored to the boxes according to the uploading sequence of the sales data, namely asThe first scan is then reverted to Ar1First single item of box, while reducing Ar1And the corresponding logistics information goes to the source database, and so on. The customer obtains the sold information of the single product when scanning and inquiring through the mobile phone again, and can check and trace the whole productThe process.
The principle of secondary boxing is that one box is full and is automatically and smoothly packed. Finally, the single-item information is restored to the boxes one by one and then is put into a source tracing database until rqkAnd (4) completely restoring the single product to the box, and finishing the whole tracing process.
If the whole box is sold, the box is kicked out (the single product which is not scanned for secondary box packing is loaded into the box by default), and the single product which is restored to the box automatically extends to the next box.
When the commodity is inquired before sale, the basic information of the commodity single product can be inquired, but the whole logistics tracing process can not be inquired, and the inquiry information is recorded at the same time.
Step S207: and confirming and randomly spot-checking the self-service scanning checkout through the two-dimension code in the step S204, namely confirming and randomly spot-checking the user who pays immediately.
The instant payment is a new attempt for the current payment mode, so that a payment voucher needs to be shown when the user leaves the store, and meanwhile, the user randomly checks the store to ensure that the commodity is paid. The specific operation is as follows:
after the customer finishes the self-checkout, an encrypted two-dimensional code certificate with bill information is generated, the generated two-dimensional code certificate is scanned through a scanning device which is connected with a statistical database in the store when the customer leaves the store, and the customer can leave the store after confirmation.
Staff in the storefront randomly check paid customers, and the order is confirmed by scanning the payment two-dimensional code voucher of the customer and scanning the single product code of the commodity. As the existing payment modes are all real-name systems, once a problem occurs in spot check, the payment modes are notified on the platform to play a warning role, and the shop online on the platform cannot be consumed when the warning level is reached.
Through the above instant payment mode, no matter the commodity single product with the single product code is settled through the counter cash register terminal or self-service settlement of the customer, the system can automatically record the sales information of the commodity single product.
Because the coding rules of the single item code and the box code realize one item code, even if no correlation of related logistics links exists, a series of correlations made by the single item code and the box code in a tracing source database already put an end to the possibility of counterfeiting codes; on the other hand, if the commodity single product is determined to be sold, the sold information of the commodity can be displayed through the inquiry of a third person, and the payment and the sale can not be carried out again, so that the circulation of counterfeit goods is stopped.
