GPS Ambulance Tracker

Published on 18 Apr 2022. Written by Vasanth Vidyakar

Ambulance is a concept that is made to help the suffering people instantaneously to reach the medical facilities on time. This vehicle is used to move patients quickly to the critical care in case of emergency situations. They are also used for other non-critical purposes like transfers between the hospitals, organ or blood transfer etc. but nonetheless it involves a significant amount of importance on comparison with the other conventional vehicles.

Ambulances will be equipped with critical tools and will have well trained responders who can come to the site quickly and help the person in need with the lifesaving actions. For such kind of vehicles safety is the foremost thing that anyone should provide. For this the proposed system is GPS tracking systems which can be implemented onto the ambulances and track their movement.

This will save a significant amount of time in reaching the patients in need by directing them in the shortest possible route, than the conventional way where there will be huge traffic. This GPS tracking system also facilitates the vehicle management solution effectively and deploy them according to the needs. This makes the GPS an important asset for the ambulances and medical institutions.

These ambulances that are fitted with the GPS will gather the location information from the satellites and send it continuously to the remote server with the help of GPRS enabled device. This data can also be given to the persons at the destinations so that they can see and guide the driver accordingly.

This entire vehicle GPS data will be sent to an off-site server instantly where it can be viewed by hospital management through their mobile phones or hospital computers. And it can also be programmed to alert hospital management if for some reason an ambulance leaves a safe zone or is driving at excessive rates of speed when there is no emergency.

Project Description:

GPS Modem: GPS modem get connected with the required satellites. Then it calculates co-ordinates of location. Then Microcontroller receives data from GPS modem.
Microcontroller: Microcontroller communicates with Liquid crystal display. It also sends data to GSM module. 8051 communicates with input devices and output devices
AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory. This is a powerful microcontroller which provides high flexibility and cost effective solution to many embedded control applications. It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry.
LCD Display: Longitude and latitude is shown on LCD display
GSM Modem: SMS is sent to user with the help of GSM modem. User can send SMS all over the world via GSM network
MAX232: MAX232 is required since the communication level of 8051 and GSM modem is different
Keypad: User can send emergency message using keypad

Interfacing GPS with 8051 Microcontroller:

GPS – Global Positioning System is generally used to determine the location of a vehicle or a person from a remote location. These GPS modules are generally used to provide the location, position and navigation services to the users from anywhere on earth. There are about 24 to 32 satellites which facilitates the seamless working of GPS.

The main application for the GPS involves mapping, tracking and surveillance. The GPS module calculates the position of any user, by recognizing the signals that are transmitted by the satellites. GPS receiver calculates the distance to each satellite and the raw data is converted to latitude, longitude, altitude, speed and time.

Software requirements:

Keil Uvision 3: Keil Software makes C compilers, macro assemblers, real-time kernels, debuggers, simulators, integrated environments and evaluation boards for the 8051, 251, ARM and XC16x/C16x/ST10 microcontroller families
Programming language: Embedded C language
