INTRODUCTION:
Presently in India defense system, all section of the defense system i.e. army, navy and air force are facing a problem of tracking the solider and his status. Presently soldiers are communicated over a radio line to indicate the location and status of the each soldier in the war field... But it has been proved that these methods are not efficient methods for tracking. During war time there will be reports in newspapers about missing of soldiers. So we are focusing on this issue & developing a system which is very effective & capable of tracking the solider and his status anywhere in the world.
In this project we will fix a system in soldier’s pocket. That system has a sensor which constantly monitors the heartbeat of the soldier. When a soldier is hit or injured in the war his heart rate data can be collected using the sensor used...The location of the soldier can be tracked using GPS (GLOBAL POSITIONING SYSTEM).Thus the heart rate and the location of the soldier can be sent to the base unit usingGSM (GLOBAL SYSTEM FOR MOBILE COMMUNICATION) technology.
DESCRIPTION OF THE BLOCK DIAGRAM
89C51 Microcontroller :
In this project 89C51 Microcontroller will play the major role as a controller of all the devices. It gets the signals from GPS receiver unit, & outputs the respective results on the LCD Module only if user requires or sends the GPS data through mobile using GSM technology. It also receives input from the sensor and based on its value it communicates with the base station.
GPS Receiver with antenna :
We are using the GPS module to find out self location of installed place. It provides latitude, longitude & altitude above the sea level. GPS antenna has to be connected to this receiver & itself exposed to sky surface to receive the GPS data.
GSM Mobile Unit :
This unit is the messenger between the soldier and the base station. This unit consists of transmitter & receiver. This unit receives instructions from the base station and also transmits the soldier status to the base station.
LCD display :
In this system we can use LCD display as an additional device. If the soldier needs the self location it displays the GPS data.
89C51 Microcontroller
In 40 pin AT89C51, there are four ports designated as P1, P2, P3 and P0. All these ports are 8-bit bi-directional ports, i.e., they can be used as both input and output ports. Except P0 which needs external pull-ups, rest of the ports have internal pull-ups. When 1s are written to these port pins, they are pulled high by the internal pull-ups and can be used as inputs. These ports are also bit addressable and so their bits can also be accessed individually.
Port P0 and P2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory. Port 3 has multiplexed pins for special functions like serial communication, hardware interrupts, timer inputs and read/write operation from external memory. AT89C51 has an inbuilt UART for serial communication. It can be programmed to operate at different baud rates. Including two timers & hardware interrupts, it has a total of six interrupts.
GPS :-
The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible by anyone with a GPS receiver with some technical limitations which are only removed for authorized users.
The GPS program provides critical capabilities to military, civil and commercial users around the world. It is an engine of economic growth and jobs, and has generated billions of dollars of economic activity. It maintains future war fighter advantage over opponents and is one of the four core military capabilities. In addition, GPS is the backbone for modernizing the global air traffic system
