The document describes a safety system for school children that uses RF transmitters and receivers along with a GSM modem. A transmitter is placed in each child's school bag that sends identification data to a receiver at the school. It also sends SMS messages to parents to notify them when children enter or exit school grounds. The system aims to safely monitor children and notify parents and schools of their locations.

2.  A lot of children need to commute between
homes to school every day.
 In recent days safer transportation of school
children has been a critical issue.
 This project intends to find yet another
solution to solve these problems by
developing a safety system that will control
the entry and exit of students from the school
through an advanced methodology.
 The whole developed system will
implemented inside the school bag of each
child.

3.  School buses transfer millions of children daily in
various countries around the world.
 While there are many issues that might disturb the
parents regarding the safety transportation of school
going children.
 To overcome the above mentioned problem we have
designed a school bag which contains system which
will provide detail information about the child.
 The work intends to look into introducing access
through tracking system that will help the school
Children transportation in a secure and safer way.
 This system does several tasks, including identifying
personal information (E.g. Name) of each student using
RF transmitter/receiver pair.

4.  System uses the autonomous clustering technique
to monitor the children in group and when
separated.
 School bag of each student is provided with a RF
transmitter along with a GSM modem.
 The GSM modem is used to send the message to
the parents.
 It uses PIC 16F877A microcontroller.
 System will handle, safe route planning, rerouting
of routes, position tracking by sending exact
location to parents, safety enhancement
applications.

5.  Whole system is divided into two parts: Transmitter
and Receiver.
 The transmitter section of the system consists of a
RF modem along with a GSM modem for sending
SMS to the parents and school authorities.
 The SMS send to the parents and school contains
the details about the location of the child.
 This transmitter section is implemented in the
school bag of each child for the safety.
 The receiver section also consists of a RF modem to
make communication with the RF transmitter.

8.  In this system we have designed a school bag for the students which contains
a transmitter section of the system.
 This part of the system consists of a RF modem in which detail information
of that particular child carrying the bag is saved.
 A GSM modem is also placed in the transmitter section, which is used to
send SMS to parents about the child.
 A receiver section is designed and implemented inside the school premises.
 When the child enter inside the school, the transmitter will transmit the data
to the receiver.
 Receiver will receive the data and make entry record of that child.
 After entering the school premises, GSM will send a message to parent that
the child reached school safely.
 When at the end of the school, child exits the school premises the system will
again generate a message about the leaving of child from the school premises
and delivers the message to the respective parents.
 When one of the parents wants to check the location of their child an make
call to the system.
 System will disconnect the call and will send a message to the calling party,
which includes longitude and latitude of the bag of the child.
 In this way parents and school authorities can be made aware about the
position of the child.

10.  High performance, RISC CPU.
 High current sink/source: 25mA/25mA
 All single cycle instructions except for program branches which
are 2 cycle
 Operating speed: DC - 20 MHz clock input DC - 200 ns instruction
cycle.
 Up to 8K x 14 words of Flash Program Memory
 Up to 256 x 8 bytes of EEPROM data memory
 Only single 5V source needed for programming capability
 Processor read/write access to program memory
 Low-power, high-speed CMOS EPROM/EEPROM technology.
 Programmable code-protection
 Wide operating voltage range: 2.5V to 5.5V.
 Commercial and Industrial temperature ranges

11.  CC2500 RF Modem is a transceiver module
provides easy to use RF communication at 2.4 Ghz.
 Supports Multiple Baud rates (4800/9600/19200/3
8400).
 Works on ISM band (2.4 GHz) which is
reserved internationally so no need to apply for
license.
 Designed to be as easy to use as cables.
 No external Antenna required.
 Plug and play device.
 Works on 5‐9v DC supply.
 Standard UART Interface.

14.  This GSM Modem can accept any GSM network operator
SIM card and act just like a mobile phone with its own
unique phone number.
 Advantage of using this modem will be that you can use its
RS232 port to communicate and develop embedded
applications.
 This GSM modem is a highly flexible plug and play quad
band GSM modem for direct and easy integration to RS232
applications.
 Highly Reliable for 24x7 operation with Matched Antenna
 Status of Modem Indicated by LED Simple to Use & Low
Cost
 Quad Band Modem supports all GSM operator SIM cards

15.  The system is safe and cost effective for the
safety point of view.
 Fast response for any uncertain action or
incident about the children.
 Use of RF system provides accurate data to
school authorities and parents.
 Use of GSM modem provides a feature of
remote monitoring of the child.

16.  School bag of the student in which RF
transmitter is implemented should be always
active.
 The GSM modem should also always be in
coverage area.

17.  If any one of the students lost the bag then
proper information about that child should not
be provided.
