标准柜号构成基本概念:采用ISO6346(1995)标准。
标准集装箱箱号由11位编码组成,包括三个部分:(4位英文字母+6位数字+1位校验码)
1、 第一部分由4位英文字母组成。前三位代码 (Owner Code) 主要说明箱主、经营人,第四位代码说明集装箱的类型(所有海运柜子的第四个字母,都是U,是用于海运集装箱的代号)。列如CBHU 开头的标准集装箱是表明箱主和经营人为中远集运。
2、 第二部分由6位数字组成。是箱体注册码(Registration Code),用于一个集装箱箱体持有的唯一标识。
3、 第三部分为校验码(Check Digit)由前4位字母和6位数字经过校验规则运算得到,用于识别在校验时是否发生错误。即第11位数字。
根据校验规则箱号的每个字母和数字都有一个运算的对应值。箱号的前10位字母和数字的对应值从0到Z对应数值为0到38,11、22、33不能对11取模数,所以要除去
第N位的箱号对应值再分别乘以2的N-1次方 (N=1,2,3………..10)
例如:箱号为CBHU3202732的集装箱它的第1位代码为C,
它的代码值=代码的对应值×2的0次方 =13×1=13。
类推第2位代码为B
它的代码值=代码的对应值×2的1次方 =12×2=24
以此类推得到箱号前10位代码的代码值。
将前10位的代码值乘积累加后对11取模
箱号为CBHU3202732的集装箱前10位箱号的代码累加值=4061,取11的模后为2,就是这个箱号第11位的识别码的数值。
公式
校验码S=∑Ci*2
以此类推,就能得到校验码。
