/*****************************************************************************************************
* 作者：Ken *
* 日期：2012,8,19 *
* 功能： *
* 注意：1.由于是軟件仿真的原因，每次仿真時只有卡1在斷電后完全正確，其他卡斷電后可能會在輸入密碼時 *
* 出現(xiàn)密碼錯誤。 *
* 2.剛開始我想實現(xiàn)利用定時器實現(xiàn)操作倒計時，但多次試驗后都沒有正常工作，希望有興趣的朋友試試 *
* 3.其實還有很多的功能可以實現(xiàn)，例如在取時任意取，操作倒計時等，大家有機會可以做做， *
* 大家共同進步。
