基于51单片机的IC卡智能楼宇门禁系统的设计与实现

基于51单片机的IC卡智能楼宇门禁系统设计与实现(代写本科论文多少钱?)
摘要:此设计是基于单片机的IC卡智能楼宇门禁系统设计。IC卡(Integrated Circuit Card)即集成电路卡,将带有识别信息的IC卡写入到门禁考勤机,然后将感应式读卡器和电磁门锁和手控开关与门禁考勤机连接起来 ,当将带有识别信息的IC卡靠近读卡器时,读卡器会识别IC卡的信息并传输到门禁考勤机,使电磁门锁打开,反之则不开门,如果是没有识别信息的卡刷卡三次,系统会锁死1分钟并发出蜂鸣声报警提示,1分钟过后才可以正常刷卡,此期间即使是已注册的IC卡也无法刷开。该系统在商业、医疗、保险、交通、能源、通讯、安全管理、身份识别等领域得到广泛应用,尤其在企业公司几乎所有的公司都用其用作考勤,区域的进入权限。本设计的基本组成:此设计的读卡器采用STC89S52单片机作为控制器,有上电、手动复位电路、晶振电路以及LCD1602液晶显示器显示IC卡信息、继电器模拟电磁门锁、发光二极管用作模拟开门指示灯、带有I2C总线接口、具有掉电记忆功能的E2PROM存储器的24C02芯片组成。
The design and implementation of IC card intelligent building entrance guard system based on 51 Single chip microcomputer
Abstract :This design of the IC card intelligent building entrance guard system design. IC means Integrated Circuit Card or Integrated Circuit Card, IC Card written with identifying information to access attendance machine, then the induction Card reader and electromagnetic locks and hand switch and access control attendance machine, and when the IC Card with identifying information near the Card reader, the reader will identify the IC Card information and transmitted to the access control attendance machine, electromagnetic locks open, do not open the door, conversely, if there is no identifying information Card charge three times, the system will be locked for 1 minute and beeping alarm prompt, can the normal charge after 1 minute, even registered during the period of the IC Card can't brush away. The system in commercial,health care, insurance, transportation, energy, communications, security management, identity, and other fields is widely used, especially in the enterprise company almost all companies use it as attendance, access area.The design’s card reader adopts STC89S52 single-chip microcomputer is used as the controller, have access to electricity reset circuit, manual reset circuit, crystals circuit and LCD1602 LCD, electromagnetic locks, light-emitting diodes (led) used as a relay simulation open lamp with I2C bus interface E2PROM chips was introduced to 24 our fleet of memory chips, with functions of power lost memories.
