COMMUNICATING WITH RFID
READER
Communication Methods
• Web interface
• Socket
communication using
– Command/Response
channel (Port 50007)
– Event Channel (Port
50008)
Communicating with RFID Reader
• We used Java driver for event-based
communication with RFID reader
• First initialize the device
• Then the device sends some information when an
event occurs
• Event types used: tag arrival, tag depart
• Each time an event occurs, we insert required
information to our database
– We record when which car enters to or exits from
which slot
Part 3
DATABASE
Database
• We used MySQL
• We constructed the database using SQL
“CREATE TABLE” statements
• We used JDBC to connect to the database
from Java

Slot 1 is full
Slot 2 is empty
• We can check Depart Time field to understand
whether a slot is currently full or not
• Since we know which car park each slot belongs to
and total number of car slots, we can find out the
number of free slots in a car park.
Work to be done next
• To design a GUI for database operations on
the server
• To design a GUI for PDA application
• To design a protocol between the server and
PDAs
