Any student tracking & management web-based(STM) system consists of several tracking devices(inserted in critical spots inside the facility andoutside the facility) and a Web-Based server .
Tracking devices consist of two main parts:
- The first part is the identification system which isnecessary to identify a specific student.
-The second important part is the devicetransceiver which provides the ability for thetracking device to communicate with the web-based server by using of a certain protocol or
standard.

This project is a student tracking system using
RFID technology.
Radio Frequency Identification (RFID)
technologies allow the transmission of a uniqueserial number wirelessly, using radio waves.
The two key parts of the system that are needed
to do this are the RFID 'tag' and the 'reader
Attaching an RFID tag to a physical object allows
the object to be 'seen' and monitored by existing
computer networks and back-office administration
systems.

Each RFID reader will be connected to the
facilitys web server through a communication
device like GSM module.
This module will connect the reader via ShortMessage Service SMS, General Packet
Radio Service GPRS and Email, these
communication techniques will convoy data
between the readers and the server.

This project can be also considered as a
prototype for many applications that need to
identify humans or objects and communicate
with a particular server.
It is considered as a very important approach
for anyone who has an idea related to manyfields like identification, tracking, management
and security.

RFID Readers & Tags.
In our project, we choose to build it and
provide a commercial RFID reader with its
compatible tags in order to complete the
system in the case of the failure in building thereader manually.
The reader that we built is designed by
microchip, it is a FSK anti-collision RFID
reader, we used this design because it is the
only design we found that solves the problem
of collision between tags.

The reader that we brought is called ID-20
RFID reader from ID-Innovations, This is a
very simple to use RFID reader module. With a
built in antenna.
7/31/2019 Student Tracking Managemenet Web Based System

The ID-20 features are: 5V supply
125kHz read frequency
EM4001 64-bit RFID tag compatible
9600bps TTL and RS232 output
Magnetic stripe emulation output
Read range of 200mm

The tag which will used with the ID-20 reader is a simple 125KHz tag, These tags come with a unique 32-bit ID and are notre-programmable. Card is blank, smooth, and mildly flexible.
The features of these tags are: EM4001 ISO based RFID IC
125kHz Carrier
2kbps ASK
Manchester encoding
32-bit unique ID
64-bit data stream [Header+ID+Data+Parity]

Monitor Computer.
The monitor computer will be a normal computer hasan access the internet via a certain IP address; also itwill be connected to a GSM device in order to receiveSMS messages from the readers and send messages
to parents or other individuals. The software functionality is to receive data from the
RFID readers from the internet by listening on acertain port in order to get the data from the internetor by receiving SMS from the readers in the case ofSMS usage.
It will work basically as a log page for students andwill provide time of the events which is important toknow the last place of each student.

The GSM module that we used in the project
for receiving and Sending SMS is SAMBA 75,
it was available with one of the assistants in
the department so we used it in order toreduce the fees of the project.

GSM Module
In this section we are about to discuss three
cases: the case of using SMS, the case of using
GPRS,the case of using Email and the interface
between the PIC and the GSM module. In the first place, configuring the device to work is
the most important section in order to start using
the device, providing the device with the suitable
voltage supply, the suitable serial application likeHyper terminal and the suitable baud rate is very
important factors to guarantee that the device will
work.

The computer of the facility must be connected
to the router (or the gate way) by the usage of
static NAT (Network Address Translation)
which provides a one-to-one internal to publicstatic IP address mapping.

Static NAT

For our project we used the dial up connection
to test the GPRS connection because Dial up
connection doesnt depend on NAT or private
IPs. It depends on the usage of real IPs each time
the client uses the connection.
i.e. there are no other clients share the sameIP as in the case of the usage of private IPs
and NAT and the test was successful.

The case of using Email
Using email is very important because it canreduce the cost of project by saving the fees ofthe static IP, there will be no need to use static IPwhen we can use email because email can reach
to any computer any where depending on thedestination email address.
In general, sending emails can be done by usingSimple Mail Transfer Protocol (SMTP).
It is an Internet standard for electronic mail (e-
mail) transmission across Internet Protocol (IP)networks. So a connection to the SMTP server ofthe Email domain that we want to use is essentialto send an email to any destination.
