Wireless access system
Sekyra, Jaroslav ; Honzík, Petr (referee) ; Fiedler, Petr (advisor)
This diploma thesis describes practical realization of entrance terminal, which enables transmission of data thanks to radio module ZigBee PAN4551 and Ethernet module Rabbit RCM3200. This entrance system uses Mifare RFID cards, with whose user will identify at the entrance terminal of the guarded object. Data are sent to server station by radio module ZigBee or Ethernet module Rabbit during demand of entrance. The database of all entrance rights of all users is stored on this server. Data system works up received data and sends them back to the terminal. One part of these data is the information about enabling of user entrance. The database system makes a list of passing through users. In the first part of this work whole conception of entrance terminal is suggested. Then basic demands of each block are described in details as well as their placement in guarded object. Next chapters describe basic function of terminal, electrical scheme, and system of power supplies for the access system. Also individual hardware components are chosen and described. In the on of the last chapter there is flow-process diagram of main loops for individual variants of terminal and interrupts functions from timer, serial link and external input from radio network MC13193 drawn. In the last chapter there is a show of server data application “AccessServer” and his basic description.
