模拟电信计费系统的设计与实现
要求：（1） 计费功能。根据存放在源数据文件中的通话记录和长途费率文件对每一条通话记录计算其通话费用，并将结果保存在费用文件中。其中：
通话费的计算方法如下：
通话费＝长途电话费＋本地电话费
长途电话费＝费率（元/分钟）×通话时长（分钟）
(通话时长不满1分钟的按1分钟计算)
本地电话费为：3分钟以内0.5元，以后每3分钟递增0.2元。
（2） 话费查询。输入一个电话号码，从费用文件中统计该电话号码的所有本地话费、长途话费，并从用户文件中查找其用户名，最后在屏幕上显示：
用户名 电话号码 本地话费 长途话费 话费总计
（3） 话单查询。输入一个电话号码，查询并在屏幕显示该用户的所有通话记录，格式为：
用户名 主叫电话号码 被叫电话号码 通话时长
(Design and implementation of simulation of telecommunication billing system
Requirements: (1) the charging function. According to the calculation of the call charges stored in the source data file in the call records and the long rate documents for each call record, and save the results in cost file. Among them:
The following conversation method to calculate the fee:
Long distance telephone calls =+ local telephone fee
Long distance telephone fee = rate (yuan/minute)* call time (minutes)
(call time less than 1 minutes to 1 minutes)
Local call: 3 minutes 0.5 yuan, increasing 0.2 yuan every 3 minutes later.
(2) calls inquiries. Enter a phone number, all local calls, long-distance calls statistics the phone number from the cost in the file, and find the user name from user file, and finally displayed on the screen:
The user name phone number local calls long distance charges charges totaling
(3) if a single query. Enter a phone number, query and display all the call records of th)

RFID_UHF_VC
RFID_VC++6.0源码_RFID读写
提供了RFID的开发源码，用VC编的，展示RFID卡如何加密，如何自毁。串口通讯支持RS-232(RS232)，RS-485(RS485)，波特率可选,RFID的天线可选，读卡频率可调。提供了控制RFID读卡功率的方法，功率从0至29可调，距离最大10米以上，该源码可用于交通、物流、运输、仓库管理、比条码技术强大。用于毕业论文答辩中，可以演示，程序看懂后，就对RFID整个工作原理较为了解。支持ISO18000和EPC_GEN2等类型的RFID卡。
VC++6.0的工作空间是“t1121.dsw”(RFID_VC++ 6.0 sources yard _ RFID read-write has provided the RFID exploitation source yard , used VC to weave, show how encrypted the RFID card , how to destructs self.
