The GPS enabled emergent tracing and nearest facility avaliance system uses AVR microcontroller

ATmega16. In this, the inbuilt ADC receives analog data from sensors and converts it to digital

data and passes it to the microcontroller. This system is to attempt to design a tracking unit for

the emergency situations. The android phone itself acts as transmitter and relay station forms

using ATmega16 microcontroller, SIM300, LCD DISPLAY 16X2, power supply section.

I. INTRODUCTION

The proposed embedded system uses GPS for tracing exact location of an affected person and the GPS

coordinates of the same is transmitted to the relay station. The transmission of GPS coordinates is carried

out by Android Application. The relay station is developed using Atmega16 Microcontroller with Sim300

GSM module. The relay station enabled with GSM and GPRS can find the nearest available emergency

facilities that can be provided to the affected person. The nearest facilities are tracked by comparing

difference of distance vector with distance vector of affected person using the android application.

II. SYSTEM OVERVIEW

The block diagram of system prototype is shown in figure (1). The bridge rectifier is used to convert the

9V supply output of transformer into DC voltage. A voltage regulator IC 7805 is used to obtain fixed

output voltage of +5V. Separate supply of same specification requirement is used for microcontroller and

GSM module. The microcontroller used is ATMEGHA-16 and GSM modem is SIM-300. The TXD pin of

microcontroller is connected to the RXD pin of GSM model and vice–versa.

The below figure (3) shows the circuit diagram in which overall architecture of system can be

summarized. It shows interconnection between microcontroller, GSM Modem and LCD display.

IV. HARDWARE AND SOFTWARE REQUIREMENTS

1. Power Supply: The power supply used in this project is in figure (4). The step down transformer is

used which convert 9-0-9 V. We used bridge rectifier to convert the 9V supply output of transformer

into DC voltage. A voltage regulator IC is used to have the fixed output voltage of +5V. For

microcontroller and GSM module separate supplier are used of same specification requirement.

2. Microcontroller Atmega16: The ATmega16 is a low-power CMOS 8-bit microcontroller based

on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle,

the ATmega16 achieves throughputs approaching 1 MIPS per MHz allowing the system designed

to optimize power consumption versus processing speed.

3. GSM Module: For sending message, a GSM Module named SIMCOM 300 with RS232, power

supply, buzzer and audio interface are used. This can be connected to PC by using a USB to Serial

Adaptor. Terminal programs such as Real term are used to send & receive data. The interface

between GSM Module and microcontroller can also be done directly with the help of wires. GSM

Module works with AT COMMANDS where AT stands for Application Terminal.

4. Inter Connection Between Microcontroller And GSM Module: Receiver Pin (Rx) of

Microcontroller is connected to the Transmitter Pin (Tx) of GSM Module and Transmitter Pin (Tx)




of Microcontroller is connected to the Receiver Pin (Rx) of GSM Module. Also Ground Pin (GND) of

both are connected as in figure.(5)

5. LCD Display: The display used here (shown in fig. 9) is 16x2 LCD (Liquid Crystal Display) that

displays 16 characters per line by 2 lines. A very popular standard exists which allows us to

communicate with the vast majority of LCDs regardless of their manufacturer. The standard is

referred to as HD44780U, which refers to the controller chip which receives data from an

external source (in this case, the Atmega16) and communicates directly with the LCD. The 44780

standard requires 3 control lines as well as either 4 or 8 I/O lines for the data bus. Here we are

using 8-bit mode of LCD, i.e., using 8-bit data bus.

6. PCB Layout: PCB Layout is fabricated using PCB Express software. Refer figure (6) for layout.

V. RESULT

AT commands with GSM/GPRS MODEM or cellular phone can be used to access sms services, they were

used to control MODEM. The Android application consists of location sensing file with extension .apk

with a purpose to trace the location of affected person to fined nearest emergency facility that are most

nearby. This application is installed on Android phone. After running application one enters the server




number and has to click on “Send Location”. The global positioning system (GPS) determines the GPS

coordinates of a person to provide emergency facilities. Accordingly, microcontroller ATMEGA16 finds

the nearest available facility by comparing the difference of the distance vector with the distance vector

of that affected person.

If X be the subject/affected person whose location is required to be traced. The GPS will trace the co-

ordinates of location of that subject X. The receiving station will get these co-ordinates in the form of SMS

that is received at server/receiving station as follows:-“Please send Ambulance at the location: Latitude:

20,3947648,Longitude: 78,086835 Please send Ambulance at the location EAT+CREG?

VI. CONCLUSIONS

This prototype system is an attempt to design a tracking unit for the emergency situations. This project

had tried a simple way to find the emergency facilities that are most nearby to the affected person. The

android application helps to find location of the person and providing them nearest available emergency

facility that are most nearby to that affected person. The nearest facilities are tracked by comparing

difference of distance vector with distance vector of affected person. Using this system and with a simple

android application we are able to access the emergency facilities.
