Abstract- In the modern world people work hard to earn
money and to live a sophisticated life. Parents are worried to
ensure that their child is 100percentsafe when they leave the
steps out. Many papers addressed this issue in different ways
such as by passing information through SMS comprising of
GSM and RFID. The existing system shares the location and
images of the environment in case of emergenciesonly suchas
accidents, break down, fire accidents to the relevant
authorities. Taking this problem as a concern we propose a
new innovative and smart idea for ensuring the safety of the
child. This is a full duplex communicationsystemcomprisingof
RFID, Raspberry pi which is integrated with InternetofThings
(IOT). It sends the information to their parents as soon as the
child reaches or leaves the school. In case of any problems or
the child does not reached the home/school within a
particular time then the system proactively questions the
school authority/parents and sends GPS location to the
parents as well as the school.
Key words: Student monitoring, Raspberry pi, Bi
direction communication, Database.
1. INTRODUCTION
In today’s world, ensuring safety and security has been one
of the major concerns. Especially when it comes to children,
parents, organization like school are way more concerned
and worried to ensure that their child is 100 percent safe
when he leaves his steps out. With technology
advancements, we would like to highlight a new step being
taken for ensuring the safety of children outside. The RFID
technology locates the child position GSM will pass
information about child to his or her parents only. It will
receive the SMS/Email from the system that inform their
children only enter/exits from bus.It works in case of
emergencies only such as accidents, break down, fire
accidents by immediately sharing the location and imagesof
the inside environment of the busto the schoolauthorities.It
consists of two sides out of them one is parent module and
another is the child module. There are two android mobile
phones for the safety of the both module. It gives missing
child tracking option by student ID cards flexible for both
parents, organization.
2. LITERATURE REVIEW
As per the Implementation of Children Tracking System on
Android Mobile TerminalsJ.Saranya, J.Selvakumar describes
that children information is transmitted and received using
GSM technology. The Child module acts as a transmitter
which includes Arm7microcontroller, GSM module, GPS
module and Voice playback circuit. The receiver module
includes Android phone and monitoring database. Child
module is fixed to each and every child. The position of the
moving child is tracked by GPS and is sent to
ARM7microcontroller. When the child cries, voice playback
circuit is triggered by ARM7 microcontroller and intimation
about corresponding child is given through text message to
their parents.
As per the RFID Based School Children Monitoring
System,PanaskarPrajakta.R, Patel Karishma M al describes
that the system which consists of main units as a bus unit.
The bus unit system is used to detect when a child
enters/exits from the bus. Childs information at entry/exit
level will be recorded automatically when they pass by the
scanner. At the same time parentswill automatically receive
the SMS from the system that inform their children
enter/exits from bus. Also information of students will be
displayed on LCD display. This system willbenefittoparents,
school children’s and school administrator. Thissystem will
be also promising to enhance the safety of childduring daily
transportation.
As per the School Bus Monitoring System Using Raspberry
Pi, R.Abhishek, K.Goutamial describes about the system
which is intended to play an important role in real time
monitoring and also intended to provide safety and secure
solution to the students and parents. An SMS alert is sent to
the parents whenever their child boards the school bus and
also when the child is dropped from school at the dropping
point. Whenever there is school bus accident, the system
provides the condition of students by an E-mail and SMS
alert. The E-mail alert is provided along with the images of
the internal environment in the school bus, and the location
of emergency. An alert message is sent to the school
authority if the school bus driver carries out rash driving at
any point of time.

3. EXISTING METHOD
In existing system, a low-cost Radio FrequencyIdentification
(RFID) has been implemented. RFID is a technology whichis
used as an alternative for manual scanning in ordertodetect
human beings plugged with RFID tag.It also providesapanic
switch and two keys. Panic switch is used in case of
emergency and keys are used if the vehicle gets stuck in
traffic and also in case if vehicle break downs. On pressing
the mentioned buttons, an image of the inside environment
of the school bus along with the co-ordinates of the location
will be mailed and also a message will be sent to the school
authorities and parents Hall Effect senor.
For tracking the vehicle using GPS and maintainitsdatabase,
MySQL database system isused along with advancedfeature
of Raspberry-Pi. In the database base monitoring and
updating mechanism.Date, Speed, Time at whichthe vehicle
was tracked and store into the database of Raspberry Pi.

4. 2. Description Of Proposed Method And Its
Functional Units
The block diagram shows how the rasberry pi works. It
shows how the system circuit works and how the current
flow goesthrough it. The proposed system includessensors,
control unit, Bluetooth, Wireless network and supply unit.
Bluetooth is used for transferring data and message. All of
these sensors are directly connected to the Rasberry Pi 3B
Module which has their own default program according to
their use. The working energy for the kit isobtainedfromthe
battery connected to the rasberry pi microprocessor.
The main aim of this project is monitoring the children and
screening the timing they reach home. RFID is used for
detecting ID card of the children and GPS tracking is usedfor
detecting the latitude and longitude of children when they
are in trouble. It is the transmitted throughwirelessnetwork
to the parents mobile.
4. 3. Raspberry PI 3B
The Raspberry Pi is a credit-card-sized computer that plugs
into your TV and a keyboard. It is a capable little computer
which can be used in electronics projects, and for many of
the things that your desktop PC does, like spreadsheets,
word processing, browsing the internet, and playing games.
It also plays high-definition video. We want to see it being
used by adults and children all over the world to learn
programming and digital making.
4. 4. GPS
GPS is a multiple – satellite based radio positioningsystemin
which each GPS satellite transmits data that allows user to
precisely measure the distance from the selected satelliteto
his antenna and to compute position, velocity and time
parameters to high degree of accuracy GPS delivers with
high sensitivity and accuracy with low power consumption.
GPS module design is flexible to accommodate various RF
interference.

4. 5. RFID Module
Each student is housed with RF identity card. The
indentifying information stored in the microchip transmits
to the RFID reader using an antenna. RFID reader is
equipped at the entrance and exit gate of the bus. Thereader
will communicate to the Raspberry PI microprocessor
serially using the line driver MAX 232 to verify thethreshold
value.
4. 6. Real Time Clock
The Raspberry Pi is designed to be an ultra-low cost
computer, so a lot of things we are used to on a computer
have been left out. For example, your laptop and
computer have a little coin-battery-powered ‘Real Time
Clock’ (RTC) module, which keeps time even when the
power is off, or the battery removed. To keep costs low
and the size small, an RTC is not included with the
Raspberry pi. Instead, the Pi is intended to be concerned
to the Internet via Ethernet or Wi-Fi, updating the time
automatically from the global ntp (network time
protocol) servers
5. CONCLUSION
The project is intended to be designed using structured
modeling to provide the desired results. Different
technologies have different methodologiestoimplementthe
monitoringof school bus, more preciselysafety ofchildrenin
school bus. The proposed system is intended to play an
important role in real time monitoring and also intended to
provide safety and secure solution to the students and
parents. An SMS alert is sent to the parents whenever their
child boards the school bus and also when the child is
dropped from school at the dropping point using GPS
module. An alert message is sent to the school authority as
well to parents.
