Description of the project:

Ambulance tracking with patient health monitoring system project can be used for ambulance tracking using GPS Modem. Also, it performs the function of the patient health monitoring system. These details are sent to the hospital through SMS using a GSM modem.

This project performs three main functions.

  1. Patient health monitoring through SMS.
  2. GSM & GPS based Ambulance Tracker which is carrying the Patient.
  3. To send the above two details to the Hospital or Doctor using GSM technology.

With the help of this project we can find out the location of the ambulance and at the same time, we can monitor various health parameters of a patient. These parameters are temperature, humidity, and heartbeat rate. A text SMS containing the location and values of all the sensors is sent to a Doctor’s mobile. Or we can send this text SMS to any authorized person in the hospital. Then that person can intimate Doctors about the ambulance location and patient health. By using these parameters, the doctor can do the necessary preparation for the treatment of the patient.

Sensors used in Ambulance tracking with patient health monitoring project:

  1. Heartbeat sensor: Heart beats are important for the health of patient. Heartbeat sensor works on a principle that blood in human body pumps with every heartbeat. We have used a Red LED and LDR. Patient needs to place his/her finger between these two components. Red light will be reflected from patient’s finger to LDR. And blood will pump with every heart beat. This will cause fluctuations in the light intensity. Heart beat sensor used in this project works on the above principle. It gives out high pulses with every heartbeat. It works on pure 5-volt DC.
  2. Temperature sensor: We have used a temperature sensor to measure the body temperature of the patient. This is an analog type of temperature sensor. It gives variable output voltage as per the variations in the temperature received/sensed. This will help to monitor the variations in the temperature of a patient.
  3. Amplifier: Since the output of the temperature sensor is in millivolts. So we need an amplifier to amplify this voltage. The output of the amplifier will be given to the Analog to digital converter.
  4. Humidity sensor: This sensor helps to measure the humidity. This is also an analog type of sensor. It gives variable output voltage as per the variation in the humidity. The output of the humidity sensor is directly given to ADC.

Block Diagram Description in detail:

  1. GPS Modem: Main function of GPS – Global Positioning System modem is to provide longitude and latitude of the ambulance. The GPS modem receives data from satellite. And then it gives this bunch of data to Microcontroller through serial communication. As ambulance moves along the way from patient’s home to hospital, the co-ordinates of ambulance location will change and these variations are given to Microcontroller.
  2. GSM Modem: Main function of GSM modem is to send all parameters to user or Doctor through a text SMS. For sending SMS, Microcontroller needs to give various AT commands to GSM modem using a serial communication port.
  3. Analog to Digital Converter: As Microcontroller is not able to read the analog signal or analog voltage, so we have to use ADC in between the Microcontroller and sensors. Function of ADC is to give digital output data corresponding to the input voltage received. Thus it converts the analog input voltage into the respective digital data. This data varies from a value of 00-Hex to FF-Hex. Thus it is compatible to the Microcontroller.
  4. LCD display: Liquid crystal display is used to display the values of all sensors or all parameters also LCD display is used to show the longitude and latitude received by GSP modem. LCD display is used to show messages like sending SMS, SMS sent successfully. We have used 16×2 alphanumeric display. LCD display is really useful for the person seating near the patient. This person can be family member of the patient or the staff from hospital like ward-boy, nurse or a doctor.
  5. Buzzer: Buzzer is used to give indication about the parameter crossing a threshold value. For example if temperature increases and it goes beyond certain value then the buzzer will be turned on. This is helpful so that the person near the patient in ambulance can be informed about the unwanted situation or about variation in the health parameter.

89s51 Microcontroller – The main controlling unit of the project:

The Microcontroller is the main heart of the system. It communicates with all input and output devices. It controls the whole operation of the system and the complete flow of the system. We have used 89s51 Microcontroller which is an 8051 series Microcontroller.

The following are the various functions of the Microcontroller:

  1. 8051 reads sensor values through ADC (analog to digital converter)
  2. 8051 microcontroller reads longitude and latitude from GPS modem.
  3. It reads heartbeat values
  4. Displays these values on LCD display
  5. Sends these values to GSM modem so that SMS can be sent to the Doctor or any authorized person in the hospital.
  6. Activates buzzer when any of the sensor values crosses threshold level.

Ambulance tracking in Google map: Or How to track ambulances on the map?

Once the doctor has received text SMS containing longitude and latitude then he/she can use these values to find out the location on map. There are 2 methods to find out the location on map using longitude and latitude.

Traditional and inefficient method:

The first method is the traditional and inefficient way in which ambulance locations can be found on printed maps. For example, the hospital administration person or doctor has a printed map of the city or the district in which the hospital is located. These maps have longitude and latitude like X Y coordinates on a graph. The user can manually find out the location on these maps. However, this traditional method of ambulance tracking on printed maps is time-consuming and thus it is ineffective. These printed maps are inefficient to show a detailed map or we can say it gives high-level map.

Text sms format for Ambulance tracking system

Advanced and recommended method:

The second method is the advanced and recommended method of Ambulance tracking in Google Maps. It is efficient, convenient, and useful to view the vehicle location online on internet maps. Hospital authority person can use these online maps to track the ambulance. This method is used to find out locations on Google Maps using longitude and latitude using the internet. Today’s world is internet savvy world. We are more dependent on and used to the internet. Nowadays the internet is easily available, and fast to access as well. Various websites are available on the internet which provide online maps. Google map is one of the best and most famous websites out of these all providers. Google map is a website that provides an online map of the world.

For ambulance tracking on online map, the hospital authority person should have computer or laptop and internet connection. Then once that person gets SMS on mobile then he/she can manually type these parameter of the SMS in Google map. Then once he/she clicks on view button, then Google map will show marker point on the exact location where the ambulance is present.

Various features of Google Map:

Following are various features of Google Maps which are useful for the “Ambulance tracking with patient health monitoring system” project:

  1. Zoom In: Google map has various features like “Zoom in” and “Zoom out”. Using zoom in function you can view details of any particular location.
  2. Get Direction: It also has a feature to get the direction from one place to another. This feature can be used in case of traffic or if road is blocked due to some reason. In such situations hospital authority person can guide the ambulance driver about the alternate road/path. Then driver can go to hospital from the location from where ambulance is.
  3. Places: Google map also shows nearest places which can be helpful to locate any other nearest hospital. If doctor finds that patient situation is critical and if it requires more time for ambulance to come to the hospital then the doctor/authority person can instruct driver to go to another nearest hospital. These are very rare cases but it can happen and if it does then it can cause life threat.
  4. Time to reach the destination: Google map also provides time required to reach from one destination to another destination by drive or by walk. It has few inbuilt algorithms to find out the time required depending upon the distance. However it is an approximate time since this time can vary depending upon the road conditions or the traffic situation.

Advantages of Ambulance tracking with patient health monitoring system:

  1. The main advantage of “Ambulance tracking with patient health monitoring system” is that with the help of GSM technology, the data on patient health can be sent over a longer distance through SMS. With the help of this, the doctor could have all prior information ready in hand before the patient reaches the hospital.
  2. With the use of GPS technology, the exact coordinates of ambulances can be tracked. And then the distance from the hospital can be found. Thus we can get/manipulate the approximate time for the ambulance to reach the hospital.
  3. As this system is fully automated, it does not require any human interaction. This system receives the health parameter values, longitude, and latitude, and sends SMS automatically after a period interval of time.

Applications of Ambulance tracking with patient health monitoring system:

  1. As the name suggests, this project finds its main application in hospitals for the tracking of ambulances as well as to understand the health parameter values of patients.
  2. Many industries and companies have their own private ambulance. These ambulances prove helpful and a lifesaver when any employee or worker met with an accident. Ambulance tracking with patient health monitoring systems can also be in these industries to find out the position of the ambulance carrying the injured employee to the hospital.
  3. The Ambulance tracking system can also be used in national parks or wildlife animal reserves where endangered species or rare species animals are preserved. If these animals have some disease or they have wounds due to some accident then these animals are carried from one place to another where they can get treatment for example to an animal hospital. In such situations, we can track the location of vehicles containing these rare species of animals.
  4. With a little bit of modification, this project can also be used for industrial purposes. This project can be used to track industrial vehicles carrying equipment or materials like fuel tanks, fuel containers, or gas containers. This system can be used in vehicles of scientific labs or industries carrying chemicals, radioactive materials, and explosive materials. In these cases we can use this project to track vehicle location, however, in such applications, we need to modify the project. We have to replace the health parameter sensors with respective sensors like temperature sensors, LPG gas leakage sensors, and other related sensors for the security of the material that is being carried.

Future Development:

  1. We can add more sensors to monitor health parameters.

  • Dear sir,
    can we implement automatic finding out of location on google maps instead of manually entering the co-ordinate values.i.e making possibly an interface between PC and GSM such that PC reads the message in GSM and puts on to maps automatically.

  • i just need to send a message for a doctor when ever the heart beat goes high so could u pls help me out with this projcet
