1、條碼CODE128編碼規(guī)則CODE128簡(jiǎn)介CODE128碼于1981年推出，是一種長(zhǎng)度可變、連續(xù)性的字母數(shù)字條碼。與其他一維條碼比較起來(lái)，相對(duì)較為復(fù)雜，支持的宇元也相對(duì)較多，又有不同的編碼為式可供交互運(yùn)用，因此其應(yīng)用彈性也較大。CODE128特性1、具有A、B、C三種不同的編碼類型，可提供標(biāo)準(zhǔn)ASCII中128個(gè)宇元的編碼使用；2、允許雙向掃描；3、可自行決定是否加上校驗(yàn)位；4、條碼長(zhǎng)度可調(diào)，但包括開始位和結(jié)束位在內(nèi)，不可超過(guò)232個(gè)字元；5、同一個(gè)CODE128碼可以由A、B、C三種不同編碼規(guī)則互換，既可擴(kuò)大字元選擇的范圍，也可縮短編碼的

2、長(zhǎng)度。CODE128編碼方式的編碼范圍1、CODE128A：標(biāo)準(zhǔn)數(shù)字、大寫字母、控制符及特殊宇符；2、CODE128B：標(biāo)準(zhǔn)數(shù)字、大寫宇母、小寫字母及特殊字符；3、CODE128C／EAN128:［00］～［99］的數(shù)字對(duì)集合，共100個(gè)，既只能表示偶數(shù)位長(zhǎng)度的數(shù)字。CODE128編碼規(guī)則開始位＋［FNC1（為EAN128碼時(shí)附加）］＋數(shù)據(jù)位＋校驗(yàn)位＋結(jié)束位CODE128校驗(yàn)位計(jì)算（開始位對(duì)應(yīng)ID＋每位數(shù)據(jù)在整個(gè)數(shù)據(jù)中的位置×每位數(shù)據(jù)對(duì)應(yīng)的ID值）%103CODE128編碼表IDASCIICade128ACade128BCade128CBan
