单片机与校园网相结合的门禁系统

Simple Entrance Guard System Made by Combination of Single-chip Microcomputer and Campus Network

以51单片机为核心,通过精简TCP/IP协议栈,利用RealTek公司的RTL8019AS芯片实现单片机与以太网的连接的方法;通过串口与以太网数据的透明传输方法,调用校园网数据库进行身份验证,制作简易的门禁系统。

This paper introduces a new method that makes the Ethemet connected with the Single-chip microcomputer. It is Based on MCU and reduced TCP/IP protocol. It uses RTL801 9AS accessing Ethernct. A simple entrance guard system is made by calling campus network database identity authentication; the whole process depends on the method that transmits data between Ethernet and serial interface.
