Abstract  A networked access management system based on W5100 was developed in order to realize centralized management of distributed access controllers.The system used MSP430F149, a low power loss chip, as the control core of the access controller. The realtime communication between the controller and the superior computer was realized by using W5100, a chip of the embedded Ethernet hardware protocol stack. The supervisory program of access management was designed through VC++.NET. The remote data transmission was realized by adopting asymmetric C/S communication mode and stream socket. This system transmits data reliably and has good antidisturbance feature. And the system supports for battery power, so as to solve the lock problem of the access control system caused by power failure．

Key words： access management system      real-time communication      W5100      C/S model      stream socket

基于W5100的网络化门禁管理系统设计

为实现分散式门禁控制器的集中管理,研制了一种基于W5100的网络化门禁管理系统．门禁控制器核心采用低功耗MSP430F149,与上位机的实时通信利用嵌入式以太网硬件协议栈W5100芯片实现．门禁管理软件采用VC++.NET设计开发,远程数据传输通过非对称式的客户端/服务器通信模式和面向连接的流式套接字来实现．该系统传输数据可靠,抗干扰性强,且支持电池供电,解决了市电故障带来的门禁锁死问题．
