Inspiration

United Nations Office for Disaster Risk Reduction (UNDRR) says that the total number of people who died due to disasters between 2000 and 2019 is 79,732. Therefore, a device has to be developed to mitigate this issue. The basic working of the device goes like this- Assume a Central Disaster Management System (Main Server) which will cover the disasters occurring in the entire country, and will be able to send signals/information to various other state substations (Clients of the main server/Server for the city substations), which in turn will be able to send data to the city substations (client for the state substation/server for the wearable device), which will be able to send data directly to the wearable devices. The idea implementation has to be efficiently carried out so that the overall product will mitigate the pre and post-disaster events. We also have to equip the system with map annotations so as to track the civilians during the rescue operations, via SoS generated and rescue them with minimum time lapse.

What it does

RETRIEVE will not only help to save lives but also help in carrying out the rescue operation smoothly. It will measure the pulse rate, location, and communication distance of the rescue team to ensure their safety. Also, the SOS alert will help to seek help from the nearest substation in case of emergencies. The Alert feature includes various switches on the rescue device for communication via WSN technologies. Finally, the collision avoidance system using the ultrasonic feature, lets the team carry on their work even if the environment is dark.

How we built it

RETRIEVE NETWORKING

  • The Meteorological Station (main server) will be connected to the state substations.
  • The state substations will be connected to the city substations.
  • The city substations will be connected to several subsystems which will be operated by the coordinators of the various rescue team.
  • The subsystems will be connected to the device on the rescue team member.

RETRIEVE COMMUNICATION

  • Two way communication via Twilio with the help of REST APIs
  • Real- time data monitoring via map Annotations
  • Communication based on graphs generated
  • Real-time fetching of data via event-driven APIs like socket.io

Challenges we ran into

  • Difficulty in accumulating the hardware components within a short period of time
  • Doing a survey and coming up with an innovative idea was difficult within the stipulated time
  • Integrating multiple components and synchronizing the final output was a tedious task
  • Fetching data from APIs on a real-time basis, was also a challenging task

Accomplishments that we're proud of

The accomplishments we're proud of are

  • Being able to come up with a unique idea that is in demand
  • Making the project in both hardware and software platform
  • Developing a prototype that empowers the disaster support team and general citizens

What we learned

  • Arduino coding
  • Cisco packet tracer
  • Networking
  • Interfacing
  • Backend development
  • Basic Query systems
  • Fetching data from the APIs
  • Connecting maps
  • Uploading data to the cloud
  • WSN technologies and their implementation

What's next for RETRIEVE

Development of an Android app that not only helps firefighters track people but also helps to save lives at a faster rate. The app will be built using the SOS signal generator, and if there is a fire in the apartment/building and there is no way to escape, the signal generator will be released. Furthermore, the device can be miniaturized and combined into one single module.
