The Design Ideas And The Realized Methods Of Door Check On Work Attendance System Based On The UIP And RFID

In this thesis, the design ideas and the realized methods of door check on work attendance system based on the uIP and RFID (Radio Frequency Identity Card) are mainly researched, at the same time, it also introduces the construction and application of the hardware and software system.Firstly, some background information and conception related to the thesis are introduced. Secondly, the design idea and the implementing method of hardware and software of the interconnection system hosted by MC68HC908GB60 are described in detail. The main functions of this software including the following aspects:(1) Achieve the maintenance and management of hardware for the system; (2) Communicate with the hardware equipments; (3) Realize the authorization of RFID cards and the management of personnel;(4) Using the electro-map to realize the functions of real-time data display and analysis, the fault disposal; (5) Achieve the maintenance and management of system basic data, using the date gathered by door access system to realize the function of checking on work attendance.This system adopts the Client/Server component, is implemented under Windows 2000, VB and SQL Server 2000. The software introduces modularization design method, uses serial communication, the multithreading operation and object oriented graphics disposal programming technology to develop the system.
