So this requires the development of corresponding technology, after all, society is continuously updated, like Darwin39。s theory of evolution, the survival of the fittest, for today39。s electronic products, increasingly update, the intelligent entrance guard system also have to keep up with the development of The Times. Now most of the panies need such high intelligent entrance guard system AVR16 singlechip as the master control chip has been introduced in this paper, through specialized rf IC card read/write module used to read the information, when the card has into the scope of reading card, card reader will read the corresponding card number, and through the serial number of the card to make the corresponding action. If the correct credit card operation, the door opens and shows the correct. If illegal card, alarm system will trigger, and display an error message. Design USES is fully automatic, accurate identification card serial number to access the system, the system used in the block AT24C04 EEPROM chip plays an important role, after power off can be stored password, to ensure the security of the system The humanputer interaction interface used is 4 * 4 matrix keyboard input and standard characters LCD display LCD12864 module. Use key input password operation is carried out in accordance with the correct password or not. Enter the password for user to use buttons, according to the right or wrong password to make corresponding operation, the administrator can set and change the password, to prevent password theft。 If there are illegal card or password input error, the system output part of the alarm circuit Key Words: AVR16 SCM。 RF IC card。 AT24C04 chip。 liquid crystal display。 the alarm circuit.
