基于微机的防尾随安全门禁监控系统设计

介绍了一种防尾随安全门禁监控系统的设计，说明了门禁系统的结构，详述了门禁系统的工作原理及特点，重点介绍门禁系统控制器、读卡器硬件电路的设计。门禁系统具有开关门时间、卡号记录功能；同时可在任意一读卡器上对其它任何连接到同一门禁控制器上的门进行开门密码设定，还可以通过远程的方式对联网的门禁装置中门设定开门密码。在开门者受胁迫时可输入特定报警密码，即可在开门同时发出报警信号，具有防胁迫功能。防尾随安全门禁监控系统实现了安全性、保密性、自动化、信息化的集中监控管理，确保了财产安全和人身安全。

Design of Monitoring and Controlling System for Anti-tail Entrance Guard Based on Microcomputer

This paper introduces a design of monitoring and controlling system for anti - tail entrance guard based on microcomputer, explains the structure of entrance guard systems, detailed working principle of entrance guard system and highlight on design of entrance guard system controller and reader hardware circuit. The entrance guard system can record switch time and card number; at the same time it can be in any one of any card reader connected to the same entrance guard controller to set the password to open the door, and set entrance password for network control device through remote way. This system achieved the security, confidentiality, automation, information centralized management to ensure the personal safety and security of property.
