摘要
基于ARM片内FLASH的射频卡考勤系统数据处理,其LPC2114作为控制器接受读卡器传送来的学生ID数据,参照课表对数据进行比较,得出考勤结果并储存。再将考勤结果通过以太网送到分布式数据库中,接收课表、时钟校正和读卡器控制信息,并对读卡器进行控制调整,实现其考勤。
The data processing of RFIC （Radio Frequency Identification Card） administrator system is based on FLASH in ARM chip. The LPC 214 was taken as the controller to receive the student ID data from card reader; the data was compared with the text table; then, the check results were achieved and stored. After that, the check results were sent to distributed database through Ethernet; the text table, clock adjustment and control information of card reader were received. The card reader was adjusted and controlled to realize the check.
