Application Research on Remote Door Access Management System Based on Ethernet

Aiming at the independent distribution units of multi-access system, a remote door access management system is researched and designed based on Ethernet. The system uses MSP430F149, together with W5100, to be the control core of every access system unit, and to achieve real time data communication between the access controller and the upper monitor based on TCP/IP protocols. The communication mode adopts non-symmetrical C/S model, in this model, the access controller and the remote PC are the clients, and the upper monitor is the server. The supervisory programs of the remote PC and the upper monitor are designed and developed through VC + +.NET to realize centralized management of distributed remote multi-door access systems.
