模块组配型条码编码容量研究

Study of coding capacity for bar code based on composed piece

阐述了模块组配型条码的概念及其最大编码容量的计算方法.采用组合数学中典型的 型分配问题的求解方法,得到求取分配数的实用递推公式,从而提出针对(n,k)码的兼容最大编码容量的小量模块编码容量计算方法.基于对模块数的选择,对几种模块组配型国际标准条码编码字符集的设计准则进行了讨论,验证了计算方法的正确性.

The concept of bar code based on composed piece was illustrated and the method of calculation for the maximal coding capacity was given. The maximal little-piece compatible-code capacity was calculated using the applied recursion fomula, which was derived from the solution for classic allocation in combinatorics. Discussing the principle of design for coding character volume of several types of international standard bar code based on composed piece, this method is proved to be correct.
