| Abstract: | A radio frequency IC card reading and controlling device is designed according to the requirements of Door Access Monitoring Management System. The reader device utilized MCU AT89C52 and Philips MF-RC500 chip to access the data in the IC card and Atmel flash chip AT24C256 for storing up to 6000 access records. To meet the needs for communication, access control, sound and light alarm and anti-damage, the device also supplied the digital IO interface circuits, RS485 serial communication interface and the pro... |
