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.%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.
