GH/T16829-2003/ESO/1EC1639D:1999<standard adopts 1S)/11C25390:1999 information technology - automatic identification and data collection technology - service code system! One bar code is introduced. For the purpose of text and robbery, the name of the standard is defined as "Lvliang Technology Automatic Identification Data Collection Equipment Point System Specification Bar Code", and in order to be more suitable for Chinese readers, the original standard is recorded in the original standard and the D position is "interchangeable". Compared with (3/"168291997", the main points are as follows: the standard name is changed from "interchangeable" to "positive condition" and the bar code system is also interleaved with a system. Code":
"The code evaluation algorithm uses the reference code evaluation method in TSIE\[S1:3 to replace the traditional bar code calculation method. The bar code number tracking and quality evaluation replaces the [Le's recommended safe and unified method;

The Yang Lu A promoted by the Wood Association, the appendix and the appendix are informative appendices, and the standard is proposed and attributed to the China Article Code Center. The main drafters of this standard are Wen You, Han Jingui, Cheng Hai and Luo Qiu. The technical standard is the first batch of training
This standard replaces the standard GB/16829:9978 Interlaced Code System 3GB/T16829:2003/[S0/EC16390:199]
Barcode technology is the basic technology, which stipulates the size of the code and the space composed of the code graphic flow standard, there are many ways to convert the code into a well-known code box, and the space graphic is suitable for the current code system specifications we have made. Many organizations have developed and published these code systems? Various system specifications have led to some code system conflicts and problems in the system design and application of coding equipment. Users of bar code technology need public and standard code system specifications so that they can check them in time during the development and application of standard printing.

4. 3.3.1 Character encoding The following table defines the required “character encoding”: In unary representation, 1 is represented by a character, and 1 is represented by a unit. The binary representation of the character encoding is also shown in Figure 4. A decimal table of binary encoding is used. Each character in the binary representation has 1 position, and the weights assigned to the left and right are 1, 2, and 7, respectively. The unary number is the sum of the weights of the character number, and the number of characters missing is 0. In this case, the number of positions used is 4. , to ensure that the check digit is always a whole character, the following algorithm defines the conversion of the digital number into a transaction; work: stop bar code in the number line auction regulations: method length steps:
1: the report needs to be counted according to the year verification symbol (control material counting bomb each gram counting indication A); if the number of the check digit is a countable number, the front is called a! 32 characters are characters;
4) The number can be abbreviated as follows:

The average strip is obtained from the fourth step, and each code character and word 5

data will rarely be (if there is a proofreading symbol, it will also be included in the back> The code for human recognition should usually be made together with the other party's editing. There is no code for human recognition of the start and end symbols, and the character size and font are not specified. The code for human recognition can be printed on the bar code symbol as long as it does not pass through the mountain. GH/16929—2003/ISO/1E Appendix B of C16390:1999 (Informative) Example of applying specified parameters B.1 Quality level The application standard specifies the minimum quality level that is effective with 1S0 gate F-5111, including the used diameter and optical length. The value is -.5/10/660 1.5 The symbol quality level is combined: 15 is the measured diameter test number. In this example, the diameter is .25mrr; 660 is the correct value response length, and the number of digits is m. Referring to ISI/IEC1>16, the minimum values ​​of the measured symbol parameters related to the combined comprehensive quality level can be determined B.2 Code system characteristics 1) Number of characters, change rate, number of characters: Symbol checksum, use 18 symbols with sufficient weight to connect and transmit: 5) Data checksum: No additional data checksum is required: 1 The page and content of the bar code are protected by a protection bar, 3 Size characteristics
As a user guide, taking into account the user needs and the corresponding bar code symbol production and recognition solutions, the application specification can also recommend a minimum size range of ×, but according to these standards, any symbol inconsistent with the minimum size should not become a default.
The recommended scanning size should be the larger value between 5 and the bar symbol length: Juice: Some standards recommend and define sizes as, and define maximum and minimum sizes. Generally, the maximum and minimum height of the effective element for any given bar code size will be constant and have a certain limit. + Ask for instructions. The width of the male stem is -6?X

CB/T16829--20C3/750,/TFC:16390:1999 Appendix (Informative Appendix) Interleaved 25 Bar Code Application Guidelines u.1 Automatic Recognition of Interleaved 25 Bar Code Symbols can be read by a correspondingly programmed bar code reader. The bar code reader is designed to automatically recognize traffic 25 bar codes from other code systems. The barcode can be completely distinguished from other codes, including the 1S code. When the barcode is used for automatic recognition, the following criteria shall be followed: [In the system code detection system, the nominal width shall not be greater than the single-bar code width (including 2 bars)] The barcode symbol should be less than half of the number of characters in the barcode input: In the automatic recognition system with 3S barcode symbols, the barcode symbol should have a maximum length of 3, and the ratio of A.1 and A.2 will provide protection in the automatic recognition environment. The effective set of decoders should be limited by the given application requirements to achieve the maximum system readability. .2 System conditions
The various printers, labels, and readers (installed in the system) are used as a system. Please note that any incompatibility between the components will affect the performance of the entire system. When a user specifies the printer and the barcode symbol (sealed system), the performance of the printer, barcode symbol, and reader must match the required standard values ​​to achieve the desired performance. 1.
