Abstract – In present scenario nations security has becomeimportant constrain. During war, tactics is main factor inany country’s security. The nation’s security mainly dependson army (ground), navy (sea) and air-force (air). Of whicharmy soldiers plays a crucial role and there are manyconcerns regarding safety of soldiers. As soon as any soldierenters the war field it is very vital for the army base stationto know the location as well as the health status of allsoldiers. It is also necessary for the base station to guide thesoldier on a correct path if he is lost in the battlefield. So weare implementing an idea of tracking the soldier as well as togive the health status of the soldier during the war, whichenables the army personnel to plan the war strategies. Byusing the location sent by GPS, the base station canunderstand the position of soldier (Latitude and Longitude)as well as health parameters send by GSM using bio-sensorswill give base station an idea about his health.

Keywords – Safety, Tracking, GPS, GSM, BiomedicalSensors.

I. INTRODUCTION

We are living in the technological era. where every fieldis trying to develop it self-using technology and militaryforces are no exception for it .To protect the boarders ofany nation the infantry soldiers of future will be one of themost technologically advance forces in the world. All overthe world a lot of research is going on to develop thetechnologies in which soldiers safety and nations securityis prioritize. The countries like United States, UnitedKingdom developed such systems. During war it is of lessbenefit to increase number of protective systems andammunitions until present situation is not provided at theoperational edge of military networks. On the war fieldsoldier has to face many challenges like loss in war, lowammunition, health issues, crossing borders etc. So inthese situations to get help soldier has to communicatewith base station or there should be some facility to guidehim.

For this purpose we are trying to track location ofsoldier using GPS, also trying to get his health parameterswith the help of biosensors. This information will be sendto base station using GSM. As soon as base station willreceive all information about soldier, they will be able toguide soldier about the direction, strategy and situation.Also base station will be able to provide necessary help tosoldier. In addition to this we are providing fixed question

keys which soldier will be allowed to ask to base station.Here google map is used to display the locations ofsoldiers. With the help of google map it is possible toknow the current status of war field also location of eachsoldier can be seen on single screen which will be morebeneficial for army base station to decide its tactics.

II. PROPOSED SYSTEM

The whole system is divided in to two parts i.e. soldierunit and base unit. Soldier unit is placed on the soldier’sbody and this unit is divided into three parts. i.e.Biomedical sensors, Emergency keys, GPS+GSM unit.Army base unit is at base station this unit is nothing but aPC on which all the information received from soldier unitwill be displayed. To implement this system as real time amain component required is controller. As we are usingGPS and GSM units we required two UARTS whichavailable in ARM processor.

128-bit wide memory interface and an unique acceleratorarchitecture enable 32-bit code execution at maximumclock rate. For critical code size applications, thealternative 16-bit Thumb mode reduces code by more than30 % with minimal performance penalty. Due to their tinysize and low power consumption, these microcontrollersare ideal for applications where miniaturization is a keyrequirement, such as access control and point-of-sale.With a wide range of serial communications interfaces andon-chip SRAM options of 8 kB, 16 kB, and 32 kB, theyare very well suited for communication gateways andprotocol converters, soft modems, voice recognition andlow-end imaging, providing both large buffer size andhigh processing power. Various 32-bit timers, single ordual 10-bit 8-channel ADC(s), 10-bit DAC, PWMchannels and 47 GPIO lines with up to nine edge or levelsensitive external interrupt pins make thesemicrocontrollers particularly suitable for industrial controland medical systems.B. Biomedical Sensors

There are a number of medical parameters of soldier thatcan be monitored, like ECG, EEG, Brain Mapping, etc.But these require complex circuitry and advanced medicalfacilities and hence they cannot be carried around by thesoldier. The entire system would become bulky for thesoldier. We therefore use two simple parameterstemperature of the soldier and pulse rate of the soldier,which does not require too complex circuits and can beeasily fitted into a small device that can be carried by thesoldier.1) LM 35:

The LM35 series are precision integrated-circuittemperature sensors, whose output voltage is linearlyproportional to the Celsius (Centigrade) temperature. TheLM35 thus has an advantage over linear temperaturesensors calibrated in ° Kelvin, as the user is not required tosubtract a large constant voltage from its output to obtainconvenient Centigrade scaling. The LM35 does not requireany external calibration or trimming to provide typicalaccuracies of ±1⁄4°C at room temperature and ±3⁄4°C overa full −55 to +150°C temperature range. As it draws only60 μA from its supply, it has very low self-heating, lessthan 0.1°C in still air. The LM35 is rated to operate over a−55° to +150°C temperature range, while the LM35C israted for a −40° to +110°C range.2) Pulse Rate Sensor:

Pulse rate sensor gives digital output of heart beat whenfinger is placed in between it. It works on the principle oflight modulation by blood flow through finger at eachpulse. Its dual low power operational amplifier consists ofa super bright red LED and light detector. One will act asamplifiers and another will be used as comparator. LEDneeds to be super bright as the light must pass throughfinger and detected at other end. When heart pumps apulse of blood through blood vessels, finger becomesslightly more opaque so less light reached at the detector.

With each heart pulse detector signal varies this variationis converted to electrical pulse [2].C. Emergency keys

Here we are giving 4 keys as a facility to the soldierwhere he can ask 4 predetermined questions to the basecamp. e.g. evacuation, low ammunition.D. Navigation Using GPS

The Global Positioning System (GPS) is a space-basedsatellite navigation system that provides location and timeinformation in all weather conditions, anywhere on or nearthe Earth where there is an unobstructed line of sight tofour or more GPS satellites. The system provides criticalcapabilities to military, civil and commercial users aroundthe world. This device can do accurate coordination viawireless communication, helping soldier for situationalawareness. GPS module have serial interface. Receiverinformation are broadcast via this interface in a specialdata format. This format standardized by the NationalMarine Electronics Association (NMEA)For Example:-$GPGLL,4717.115,N,00833.912,E,130305.0,A*32<CR><LF

E. Army Base UnitUpon receiving the SMS, the visual basic software sorts

the soldier’s location based on the GPS co-ordinates. alsothe health status is displayed. In this way the armyofficials can keep a track of all their soldersIV. WORKINGA. Data Acquisition Mode

In data acquisition mode ARM7 microcontrolleracquires and stores different parameter of soldier. Themain block of Wireless Data Acquisition System forsoldier is ARM7 microcontroller which is heart of thesystem, which provides monitoring and controllingactions. It senses signals from input blocks and processesoutput blocks. The software program is stored in ARM7microcontroller on chip memory, according to which itprovides the controlling actions.

The on chip ADC converts these parameters into digitalform and gives to the ARM7 microcontroller. The status

of soldier i.e. whether the soldier is in danger or not. Withthe help of keyboard (4 keys) the soldier can ask thepredefined question. The LCD block is provided for visualdisplay of the message and location. Also it continuouslydisplays the measured parameters. The RTC provides realtime clock depending on which the various events occur.Whenever emergency takes place the interrupt block givesinterrupt to the ARM-7 microcontroller. Through serialcommunication block is interfaced the PC. With thisinterfacing the stored data is transferred serially to PC, forthe analysis purpose.B. SMS Sending Mode

In SMS sending mode the GPS, GSM and the ARM7work together to track the location of the soldier alongwith SMS sending service provided by the GSM module.The system enters this mode of operation when anemergency has occurred or the user asks specifically forthis service via SMS. In case of accident GPS modulefinds the longitudinal as well as latitudinal co-ordinates ofthe location of the soldier. The ARM7 then comparesthese co-ordinates with the database stored in the externalmemory. Once the co-ordinates match the co-ordinates areconverted into location names by referring to the look-uptable which is also stored in the external memory. Oncethe location names are found out they are forwarded to aregistered number via SMS. This SMS is sent by the GSMmodule using the AT commands. The SMS that isforwarded contains information such as location of thesoldier and time and date. In this system the soldier canask predefined questions by pressing required key. Thiswill be send to base station using GSM service.

V. CONCLUSION

GPS finds location of each soldier, thus gives safety forsoldiers. As GPS coordinates are available for almost allarea of earth so soldier can be tracked anywhere at anytime. We can provide emergency help in case of badhealth of soldier and by checking health status of soldier’s.we can improve safety of soldier. Soldiers cancommunicate effectively among the headquarters and themembers of his squad. Due to the use of ARM 7 processorpower consumed by the system is minimum. Differentcircuits used are small in size and carries less weight theyare not much bulky so can be carried anywhere.
