Nowadays, the security system of the nation depending upon the enemy’s war and so the security of the soldiers is considered as an important role in it. Concerning the safety of the soldiers, there are numerous tools to observe the health condition as well as bullets on the soldiers. In soldiers security, biosensor system gives different kinds of sensors like small physiological, Barometric and Oxygen analyzer, processing capabilities and transmission modules, and can thus enable low-cost wearable unremarkable solutions for health monitoring system. The proposed system uses GPS to track the direction of the soldier in the form of latitude and longitude values. So that direction can be found easily.

GPS and GSM Based Soldier Tracking and Health Monitoring System

Designing of this system using GPS and GSM gives a wireless system for tracking the location of the soldier and observing the heart beat rate and body temperature of the soldier. The biomedical sensors used in the proposed system are sensor and beat. The temperature sensor is used to measure the temperature of the body as well as heart beat sensor is used to measure the heartbeat rate of the soldier.

One of the most important tasks in military processes is that the Soldier, not able to interconnect with control room administrator. In addition, every organization wants to apply for certain work when they communicate over the n/w owned and worked with other organizations. Therefore, without cautious planning and coordination, one group cannot interconnect with the other groups. Present a problem faced by the soldiers are; Soldier wants to identify the location. They will not get assistance during terror situation and soldiers are not trackable

Soldier Unit

Soldier unit is placed on the soldier. This unit has four parts, namely biomedical sensor, keypad, GSM, and GPS.

Heartbeat Sensor

The Heart Beat sensor gives an easy way to study the function of the heart This sensor is used to monitor the blood through a finger. As the heart services blood through the blood vessels in the finger, the blood amount in the finger changes with respect to time. Heartbeat sensor shines a light lobe through the finger to measure the light communicated to the LDR.The signal gained from the LDR is changed by the amplifier and will be cleaned and provided to the ADC.

Heartbeat Sensor

Temperature Sensor

The Temperature sensor can be sensed with the help of the LM35 sensor. This series is accurate integrated circuit sensors, whose o/p voltage is linearly related to the Celsius temperature. A Station, which is pressed directly will aware Base station and thus will not delay for heart beats to go out of the normal range.

Temperature Sensor

PIC Microcontroller

The term PIC stands for “Programmable Interface Controller”, these are standard with both industrial developers and also hobbyists similar due to their wide availability, low cost, large user base, a wide collection of application notes, and available at low cost.

PIC Microcontroller

Global Positioning System

The term GPS stands for Global Positioning System (GPS) is a space-based global navigation satellite system that offers consistent location and information about the time in all weather conditions from anywhere on the Earth when and where there is a free line of sight to four (or) more GPS satellites.

Global Positioning System

Global System for Mobile Communications

The term GSM stands for “Global System for Mobile communications”, controls as the world’s most extensively used cell phone technology. Cell phones use a GSM n/w by searching for cell phone towers in the near area.

LCD Unit

The LCD display is used to display the temperature and heart beat rate, current time, date and the position of the soldier.

LCD

Danger Switch

Danger switch is used to help in warning the Base Deference voltage

Environmental Analyzer

The environmental analyzer is used to find the situation of an environment such as the oxygen level and atmosphere pressure and also observe the real-time video of the soldier’s unit.

Webcam

A webcam is a device used to capture a video that is connected to a PC or computer n/w, frequently using a USB port, Wi-Fi or Ethernet, or build in for particular types of laptops.

Keypad

The keypad is a part of Human Machine Interface and plays a vital role in a tiny embedded system where human interaction is required. Matrix keypads are very simple in their architecture and also very simple of interfacing with any microcontroller.

Applications and Advantages

The applications and advantages of the health monitoring system include the following

• No need to go on the field
• High reliability
• Cost effective
• Efficient and very fast

From the above information(health monitoring system) we can conclude that it would help in tracking the health status of the soldier with measures of heart beats and also the temperature of the body. It would also assist in tracking his location by using GPS and GSM modem. It can send all information to the BSS (base station) so that more necessary action could be taken.
