Observing this bar code, there is really no more intuitive is to indicate the date of production of the number of segments,
This should not be the external common commodity code, but Hisense refrigerator internal issue of the bar code,
There should be a system behind it, this system can come to explain the bar code more rich information.
Of course the barcode is so long that it must also contain some basic information about the product
1?B02050050?1000P28?B1014?2
The first bit should be the flag bit, which is used to identify the category of the barcode application;
The second paragraph seems to be the product code;
The third paragraph may be the refrigerator related specifications, such as power and so on;
The fourth paragraph is most likely the date: B=11 (36 decimal, A=10,B=11,C=12) year, 10 is the month, 14 is the day,
i.e., the date of production is 2011 October 14;
The last bit is estimated to be the barcode checksum bit.
Whether the date is October 14, 2011, you can do a basic judgment based on the date you purchased it, I guess, to see if it makes sense.
Compare that to the fact that this should be an internal barcode, and the rules have to be designed by someone who can clearly determine that.
Other knowledge about the bar code you can also look at:
__________________________________
The bar code is a string of characters (number + letter combinations, such as B2009A) through the encoding + conversion,
turned into a bar + empty Between the image;
Bar code printer to print out the bar code label is the realization of the string to convert the image (label in the bar code) of the process;
The image and that string of code corresponds to the optical device can be recognized through the decoding,
These optical devices are your common scanner gun or the collector of the core components.
These optics are the heart of your common scanner or collector.
For example, ? The scanner recognizes the bar + empty image through its intrinsic optics, and then decodes the string,
and then outputs it to a computer port (USB or serial), where an application can go and read the string corresponding to the barcode,
and then do the application logic (e.g., querying the price of the clothing style corresponding to that barcode, the manufacturer, and so on).
Barcodes can represent characters, numbers, symbols and other information; common about twenty kinds:? Such as EAN-13, Code39, UPC-A and so on.
Barcode labels on the barcode is printed by the barcode label printer,? Each barcode corresponds to a set of barcode numbers,?
Different code systems and numbers print different barcode graphics.
Barcode recognition machines (such as? Barcode Scanner? ,? Collector, etc.)? is decoded by recognizing the barcode graphics;
The numbers below the barcode graphics are printed up to see the value represented by the barcode, mainly for the human eye to read;
The numbers below the barcode graphics are not cared for by the recognition machine.
In short, the general process is:
Barcode digital-> printer printing-> barcode graphic labels-> affixed to the item-> scanner item barcode graphics-> scanner recognition and decoding-> to get the barcode digital-> the system applies to deal with ...
Goods code is the external public bar code, you can apply to the National Article Numbering Center to apply for a general commodity bar code,? The use of EAN-13,? Specifically how to code has fixed rules;
If the internal use, you can also use the internal bar code,? It's just a matter of coding it according to what you're using it for,? If you want to be unique, you can use the product number + production date + running number,? If the batch management, you can use the product number + production batch ... Then use the barcode printing software? +? Barcode printer can be produced!
Barcode coding methods and applications:
1?Don't think of the barcode too profound and omnipotent,? Barcode is a set of character strings,
Whether it itself has a meaning, what it means, what it represents,? is designed by the applicant,?
Similar to an ID number.? Except that the barcode can be graphical,? It can be scanned to eliminate the need for manual entry.
2?Barcodes can be categorized into commodity codes? and? Internal code,
Merchandise code:? It is EAN13 code, which is managed by the National Code Center. is managed by the National Code Center,?
Used to indicate a specific manufacturer and model of the product,?
Generally by the manufacturer, product code, price and other information,?
The commodity code is managed by the coding center and can be scanned in major shopping malls. It can be scanned and identified in major shopping malls and stores.
Internal code:? is a barcode that is freely designed within the company according to its own needs, and can be scanned in major shopping centers.
There is no standardized rule. can be used in the employee ID, equipment ID, product ID, product packaging ID, raw material batch number and so on;
how to edit anyway, how to edit ...?
You may ask, ?
How do you recognize the information?
The barcode can contain the necessary information on its own, just like a product code, but it can also be used to identify a product that has a barcode that is not a barcode, or a barcode that is not a barcode.
Or it can just be a random unique number (e.g.? date? +? the number of the flow)? ,?
Then when the barcode is issued, the full information corresponding to this ID is stored in the backend database,?
So that when the system is scanning the bar code can go to the database to find out its corresponding information, making it meaningful!
3? Single product code,? Batch code,? Class code
a, the bar code can be unique,? For example, each product is given a unique bar code,? This is a single product code, the number is 1;
b, barcode can also represent a batch of items,? For example, a batch of raw materials,? This is the batch code,? The number can be greater than 1;
c, bar code can also represent a class of goods,? For example, for different brands, models, specifications of products issued by the corresponding bar code,?
The number needs to be scanned and entered after the barcode;
The barcode is a number,? The significance lies in how you design and utilize it,? I don't know, do you get it?
Manufacturing barcode:
1?You can order from the barcode label manufacturer, tell your style requirements and quantity, you can; (contact LENX)
2?Buy your own barcode printer? +? Barcode printing software? their own printing, bar code software CodeSoft, LabelMatrix, etc.;
(Of course, if the issue of bar codes have some special requirements to deal with, you can find a bar code software company to do a bar code printing software)
