The barcode reading system is designed for the actual medical algorithm to allow for the reading of multiple codes with missing codes. In the analysis of the whole decoding solution described in the section, the calculation of the value of 2 is shown in section 4.5. The steps for translating each barcode character are as follows: 1 Calculate the width of 8 bars (Figure 5)
Figure 5 The code size is
Convert , to the corresponding value, , and express it as a multiple of the decision width: The calculation method is as follows
If 1./1* 2./1, the area, = 2
If 2.52/11* 3.5/1, then E,3; if, 51e1. 51E, =;
If .5/11.5/1,
If 5.5+/116,5/11. Then, = 6;
If, 5/11m 7.p/11, then, = 7, otherwise the code is incorrect.
3Use a value, ,, and F as the key to find the character in the decoding table. (See Table)) Find the check value V of the character in the text, the value should be compared with the module validation formula of the text:
(1.75p (+.-6: (V + 1.)p/1. If it does not hold, the character is incorrectly recognized.
The algorithm indirectly uses the code character's validity period to find the error of a single module of the system. For more than 5 bar codes, if the first bar code character is the start character, then repeat from left to right. If the first bar code character is not the start character but the end character, then replace the code character in the opposite direction. When all the code characters have been replaced, ensure that there is a valid start character and a valid end character. Ⅲ. Use a correct symbol to verify the character.
According to the start character, switch character and change character in the bar code symbol, the character of the symbol is converted into an appropriate data interpretation.

This algorithm indirectly uses the code character's performance to find the error of the single module of the system. For more than 5 special policies, if the first bar code character is the start character, then repeat from left to right. If the first bar code character is not the start character but the end character, then replace the code character in the opposite direction. When all the code characters are replaced, it is guaranteed that there is a valid start character and a valid end character. Ⅲ. Use a correct symbol to verify the character.
According to the start character, switch character and change character in the bar code symbol, the character of the symbol is converted into an appropriate data interpretation.

conversion character 5HFT will convert the single unit from the A Korean conversion character set 4 or from the character set R to character A, and the character in the conversion character will be automatically or restored to the previous character in the conversion list.

Can be used for this course to indicate the special operation or application of the piece) start character SA (or C) and N is used for marking the system's h) (information addition to indicate the system code source reading device, the information containing the N symbol is temporarily stored in the next symbol before transmission, during transmission, it is possible to link several numbers, the symbol is located in the symbol file, if the data is compatible with the card, part of it It is necessary to make sure that the symbols are read in the correct order! When the barcode reader is initialized, the format of the barcode reader is F3, etc. as the initialization instruction. The character can appear in any part of the code. dNC is not implemented in EAN·EICC.
4.2.5 Start and stop characters
The start character trB or the end character is used at the beginning of the symbol. The end character Srop is used for analysis. 4.2.6 Check character
The check character is the last character before the end of the barcode symbol. The calculation method is shown in the table for human recognition.
4.2.7 UCEAN12B barcode start format
ICC FAN-type barcodes have a special start symbol, the formula is as follows: F: Starr AR & C FNt
This double character starts with a 128 barcode! It can be distinguished from UC/EAN! 2S barcodes are different from 128 barcodes. If a 29-year code starts with a double character, it is a JCC/EAN1 barcode. Otherwise, it must be a TC/AV code.
FN can be used as a check character (with a small chance of error). When the batch identifier is selected and its domain is included in the barcode, the above 1 is used as a separate character:
S:r Use LCFANI28 system codes to start with 4T Srsn Use CCEAAN-1 tea barcodes to set B. Su:: C IC/FAN-126 ※ The code starts with a character, usually for the data that includes the identifier in 4 or more F numbers,
4.3 Size requirements
FAN-1 barcode number The size requirements are as follows:
4.3.1 The minimum size of the module (X
) is determined by the actual size of the product and the reading equipment. The minimum size is 000 and the maximum size is 1.00. Each time the product is produced, the daily standard value of one size is reported in: a given system is used for a final change of 7
CB/ T15425—2DC2
4.3.2 The minimum size of the blank area
UCC/EAN12 bar and other symbols in the wide area is 10X4.4 Reference translation method
The reading system is designed to allow for the actual medical algorithm to be able to read multiple codes with missing characters. In the analysis and decoding method described in the section, the value of Sichuan Medicine 2 can be found in section 4.5. The steps for translating each barcode character are as follows: 1. Calculate the width of the 8 scales (Figure 5).
