The Server Design Of The Mobile Identification System Based On Wifi And Rfid

Applications of the Internet of Things have brought great convenience to the production and life. Among them, the identification system based on the RFID technology has been widely used. Nowadays, most of identification systems use wired communications which are wired complicated, costing a lot and not conductive to rewiring and expansion. With the development of WiFi technology, many cities offer covering domains of WiFi. Because wireless communication can overcome many unfavorable factors in the wired communications, the future development of the identification system will be based on wireless communication.With the study of the development of identification systems at home and abroad, we propose a design of identification system which can be moved. The system which is based on C/S model can communicate timely between server and client in wireless LAN. The server of the system is established a database with SQL Server2008and selected Delphi2010as a platform to design operation interface; clients interact with the server through the wireless network. We use Socket based on TCP/IP protocol for the system which can query labels’corresponding information and timely respond.
