一．了解一下CODE93的發(fā)展:    

1.Code 93於1982年,基於code 39之上而設計.    

2.Code93比Code39能夠編碼更大的字符集,並且擁有更高的數(shù)據(jù)容量.    

3.Code 93設計來編碼字母和數(shù)字混合信息.    

4.Code 93需要兩個校驗碼.

二．CODE93的組成部分    

1.所能表示的數(shù)據(jù)范圍:      

字母:A-Z      

數(shù)據(jù):0-9    

符號:空格、.  、%  、 contentnbsp; 、+  、–  、/    

控制碼: contentnbsp; 、+  、–  、/    

起訖碼: START : "101011110";  STOP  = "1010111101"

三．CODE93的特點   

 1.可用控制碼與其它與其他字母或符號組合可變成FULL ASSIC II字母   

 2.有二個檢查碼”C”和”K”,掃碼器讀取時并不輸出,只在掃碼器內(nèi)部檢查.    

3.檢驗碼的計算方法:      

 a.先檢查出資料對應的碼值      

 b.檢查碼C從資料的最右邊一位開始,用1-20的順序排列,若超過20位,則從頭開始    

c.檢查碼K從資料的C位開始,用1-15的順序排列,若超過15位則從頭開始.

1*3+2*9+3*38+4*14+5*13+6*24+7*12=484 C=484÷47=14 則C=14=E(對應值) K的值的計算同C

四．條形碼的基本組成

 

五．程序編碼
