Designing a soldier tracking and health monitoring system using GSM and GPS to provide wireless system for tracking the soldier location and monitoring the parameters of soldier are as ‘ Body temperature & Heart beat rate..

Biomedical sensors: Here to find the health status of soldier we are using a body temperature sensor to measure body temperature as well as heart beat sensor to measure the heart beat rate of soldier.

1.2 PROBLEM SUMMARY

One of the fundamental challenges in military operations lays in that the Soldier not able to communicate with control room administrator. In addition, each organization needs to enforce certain administrative and operational work when they interact over the network owned and operated by other organizations. Thus, without careful planning and coordination, one group cannot communicate with the other groups. Current problem faced by the military are as follows:
1. Soldier wants to know about location. he can’t do that.
2. They will not get help during panic situation.
3. Soldiers are not track able.

1.3 OBJECTIVES OF PROJECT

In this project, our main focus is to improve the communication of soldier with control room people and control plane operations. The above problem is solved as follow:
1. By using GPS, we able to give proper location about location in critical condition.
2. We are going help the soldier in panic condition, as control room people we are able to communicate with them by means of GSM. Thus we are able to help them in panic Condition.
3. We able to track them by using GPS.
[ Ref 3]

1.4 USEFULNESS OF PROJECT
In today’s world enemy warfare is an important factor in any nation’s security. The national security mainly depends on army (ground), navy (sea), air-force (air). The important and vital role is played by the army soldier’s. There are many concerns regarding the safety of these soldiers. As soon as any soldier enters the enemy lines it is very vital for the army base station to know the location as well as the health status of all soldiers. The paper has an idea of tracking the soldier as well as to give the health status of the soldier during the war, which enables the army personnel to plan the war strategies. By using the location sent by the GPS, and using biomedical sensors and GSM the base station can understand the health status and position of soldier (Latitude and Longitude).

LITERATURE SURVEY

2.1 EXISTING TECHNOLOGIES

1. Wrist Watch for Mountaineers:
The idea for our project was taken from the wrist watch used by mountaineers. The watch displays position, direction, surrounding temperature, and it also acts as altimeter.

2. Radio Collars with GPS Tracking:
Recently in the US and Australia some of the Indian students were forced to have a Radio Collar strapped to their ankles, so that their movements can be tracked by the officials. We use a similar technology which will display the soldier’s current location by means of latitude and longitude angle at the base station.

3. Tracking of Tigers:
Recently India announced plans to use a new tiger tracking system in order to crack down on ‘lazy’ wildlife guards. The new tracking system involves fitting tigers with radio collars. A GPRS (general packet radio service) device, along with the software, will be used to track the movement of the tigers.
[ Ref. 6 ]

2.2 MEDICAL PARAMETERS

‘ There are a number of medical parameters of soldier that can be monitored, like ECG, EEG, Brain Mapping, etc. But these require complex circuitry and advanced medical facilities and hence they cannot be carried around by the soldier. The entire system would become bulky for the soldier.

‘ We therefore use two simple parameters temperature and Heart Beat of the soldier, which does not require too complex circuits and can be easily fitted into a small device that can be carried by the soldier.
[ Ref. 5,7 ]

2.3 COMMUNICATION
‘ There are a number of ways in which the soldier can communicate with the base station eg.- Bluetooth, Zigbee modules etc. But most of these technologies are short range and having certain drawbacks, while the soldier may be far away in the battlefield.

‘ Hence GSM is a technology that can be used to communicate with the base station and it also has long range. Certain sophisticated GSM technologies can work even when there is fog or in a dense forests.
[ Ref. 8 ]

2.4 SENSOR SURVEY
‘ There are a number of temperature sensors like thermistor, thermocouple, RTD, but all these sensors require signal conditioning and are difficult to caliber. The signal conditioning for these sensors increases the size of the kit, hence these are not to be use.

‘ LM35: It is a low cost temperature sensor and it does not require signal conditioning, calibration is also done by software. Hence LM35 may be use.

4.1.2 GSM Module ( SIM 300 )
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. Applications like SMS Control, data transfer, remote control and logging can be developed easily.
The modem can either be connected to PC serial port directly or to any microcontroller. It can be used to send and receive SMS or make/receive voice calls. It can also be used in GPRS mode to connect to internet and do many applications for data logging and control. In GPRS mode you can also connect to any remote FTP server and upload files for data logging.
This GSM modem is a highly flexible plug and play quad band GSM modem for direct and easy integration to RS232 applications. Supports features like Voice, SMS, Data/Fax, GPRS and integrated TCP/IP stack. Indicator LEDs indicating various status of GSM module eg. Power on, network registration & GPRS connectivity. After the Modem registers the network, led will blink in step of 3 seconds. At this stage you can start using Modem for your application.

Figure No. 4.2
( GSM Module SIM300 )

FEATURES:
‘ Highly Reliable for 24×7 operation with Matched Antenna
‘ Status of Modem Indicated by LED
‘ Simple to Use & Low Cost
‘ Quad Band Modem supports all GSM operator SIM cards
APPLICATIONS:
‘ SMS based Remote Control & Alerts
‘ Security Applications
‘ Sensor Monitoring
‘ GPRS Mode Remote Data Logging
The GSM Modem can be sent commands to send or receive SMS from the PC through a com port (serial port or an usb). These commands are called as AT commands. Through AT commands we can perform several actions like sending and receiving SMS, MMS, etc. Sim300 has an RS232 interface and this can be used to communicate with the PC. Sim300 usually operates at a baudrate of 9600, with 1 stopbits, No parity, No Hardware control and 8 databits. We shall see at some of the AT Commands necessary for sending and receiving SMS.
Some of the AT commands are given in below table
Command Description
AT It is the Prefix of every command sent to the modem. It is also used to test the condition of the modem. The GSM Modem responds with an
OK or an ERROR in case of error.
AT+CSMINS? Command to check if the Modem has a sim inserted in it.
AT+CREG? Command to check if the sim is registered with the network. It checks if the sim is registered and returns the status.
ATE1 Command to turn on the ECHO. The GSM Modem continuously echo’s back the every byte of data sent to modem until a carriage return character is sensed. It processes the command after a carriage return character is detected. It is usually better to turn off echo to reduce traffic. In this case ECHO is turned on to see how commands are sent and how they are processed.
AT+CMGF=1 Command to set the communication to Text Mode. By default the communication is in the PDU mode.
AT+CMGR=1 Command to read an SMS at the index one. Generally the index depends upon the how many number of SMS that a sim can store. SIM Memory is the only memory available when GSM Modem is used and hence the number of SMS’s stored depends on the SIM. It is usually 20. Any message received is arranged in the order of arrival at specific indices.
AT+CMGD=1 Command to delete the SMS at the index 1.
AT+CMGS Command to send SMS from the GSM Modem.

Table No. 4.1
( AT Commands Utilized in Our Project )
[ Ref. 4 ]

GUIDE TO SEND AND RECEIVE SMS
For sending SMS in text Mode:
‘ AT+CMGF=1 press enter
‘ AT+CMGS=’mobile number’ press enter
‘ Once The AT commands is given’ >’ prompt will be displayed on the screen. Type the message to send via SMS. After this, press ‘ctrl+Z’ to send the SMS.

( Programmer for 89VXX )
4.1.4 GPS Receiver
A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS satellites high above the Earth. Each satellite continually transmits messages containing the time the message was sent. These signals travel at the speed of light through outer space, and slightly slower through the atmosphere. The receiver uses the arrival time of each message to measure the distance to each satellite. This information is then used to estimate the position of the GPS receiver as the intersection of sphere surfaces. The resulting coordinates are converted to a more convenient form for the user such as latitude and longitude, or location on a map, and then displayed. It might seem that three sphere surfaces would be enough to solve for position, since space has three dimensions.
Global Positioning System (GPS) satellites broadcast signals from space that GPS receivers, use to provide three-dimensional location (latitude, longitude, and altitude) plus precise time.
GPS receivers provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Earth.
Our ultra-sensitive GPS receiver can acquire GPS signals from 65 channels of satellites and output position data with high accuracy in extremely challenging environments and under poor signal conditions due to its active antenna and high sensitivity. The GPS receiver’s – 160dBm tracking sensitivity allows continuous position coverage in nearly all application environments.

Figure No. 4.4
( GPS Receiver )

The output is serial data of 9600 baud rate. The hardware interfaces for GPS units are designed to meet NMEA requirements. Generally GPS Receiver message received by GPS is in NMEA [National Marine Electronics Association] message format and NMEA protocol which is most commonly used is NMEA0183 protocol. GPS sentences beginning with the following specifications:$GPGGA, $GPGSA, $GPGSV, $GPRMC, and $GPVTG. And sentences also begins with $GPMSS, $GPZDA as shown in table 4.2.

Sentence ID Description
$GPGGA GPS Fix Date

$GPGSV GPS Satellite in view
$GPRMC Recommended minimum specific GPS/Transit Data
$GPVTG Track made good and ground speed
$GPMSS Beacon Receiver status
$GPZDA UTC Date/Time and Local time Zone

Table No. 4.2
( Formats of NMEA Messages )
The Method Of Tracking
The tracking method is based on the process of collecting continuously the coordinate (latitude, longitude) of mobile vehicle that could get from GPS receiver. After getting the coordinate, the remote soldier unit will send it to the army unit via GSM. The army unit will receive the coordinate of the soldier then displays on the screen.

4.1.5 Temperature Sensor ( LM35 )
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ?? Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ??1’4??C at room temperature and ??3’4??C over a full ’55 to +150??C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35’s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 ??A from its supply, it has very low self-heating, less than 0.1??C in still air. The LM35 is rated to operate over a ’55?? to +150??C temperature range. The LM35 series is available packaged in hermetic TO-46 transistor packages.

FEATURES:
‘ Calibrated directly in ?? Celsius (Centigrade)
‘ Linear + 10.0 mV/??C scale factor
‘ 0.5??C accuracy guaranteeable (at +25??C)
‘ Rated for full ’55?? to +150??C range
‘ Suitable for remote applications
‘ Low cost due to wafer-level trimming
‘ Operates from 4 to 30 volts
‘ Less than 60 ??A current drain
‘ Low self-heating, 0.08??C in still air
‘ Nonlinearity only ??1’4??C typical
‘ Low impedance output, 0.1 W for 1 mA load

4.1.6 Heart Beat Sensor ( Photo-Transistor )
Heart beat sensor is designed to give digital output of heart beat when a finger is placed inside it. This digital output can be connected to ARM directly to measure the Beats per Minute (BPM) rate. It works on the principle of light modulation by blood flow through finger at each pulse. ICLM358 is used for Heart Beat Sensor. Its dual low power operational amplifier consists of a super bright red LED and light detector. One will act as amplifiers and another will be used as comparator.

Figure No. 4.7
( Photo Transistor As Heart Beat Sensor )

LED needs to be super bright as the light must pass through finger and detected at other end. When heart pumps a pulse of blood through blood vessels, finger becomes slightly more opaque so less light reached at the detector. With each heart pulse detector signal varies this variation is converted to electrical pulse

4.1.7 MAX232
The MAX232 is an IC, first created in 1987 by Maxim Integrated Products, that converts signals from an RS-232 serial port to signals suitable for use in TTL compatible digital logic circuits. The MAX232 is a dual driver/receiver and typically converts the RX, TX, CTS and RTS signals.
The drivers provide RS-232 voltage level outputs (approx. ?? 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to + 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.
The receivers reduce RS-232 inputs (which may be as high as ?? 25 V), to standard 5 V TTL levels. These receivers have a typical threshold of 1.3 V, and a typical hysteresis of 0.5 V.

4.1.8 Analog To Digital Converter ( ADC0808 )
The ADC0808 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic.

Figure No. 4.10 Table No. 4.4
( Pin Configuration of ADC0808 ) ( Analog Channel Selection For ADC0808 )
The 8-bit A/D converter uses successive approximation as the conversion technique. The 8-channel multiplexer can directly access any of 8-single-ended analog signals. Easy interfacing to microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI STATE?? outputs. The design of the ADC0808 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0808 offers high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeatability, and consumes minimal power. These features make this device ideally suited to applications from process and machine control to consumer and automotive applications.

4.1.9 16 X 2 LCD Display
LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications. A 16×2 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on. A 16×2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5×7 pixel matrix. This LCD has two registers, namely, Command and Data.
The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. Click to learn more about internal structure of a LCD.
