Employee Emergency App

Winning submission to EY GDS Hackpions 2.0. A complete end-to-end platform to aid companies in evacuating large buildings during emergency situations.

Here's a video showing the project and its features (note: the video is slightly outdated, some changes have been made since then, especially to the AR features).

Features

• Three interfaces for Employee, ERT (Emergency Response Team) and command center
• Indoor positioning with trilateration using BLE Beacons and WiFi APs (RSSI)
• Image processing to automatically extract paths from map images.
  • Also places beacons at appropriate (configurable) distances
• Indoor navigation using A-star shortest path algorithm.
• Realtime communication using WebSockets and Firebase Realtime DB.
  • Realtime chat between Employee and nearest ERT
• Realtime map showing locations of everyone involved.
• Simulator to test a scenario with multiple employees and ERTs.
• AR Map view
• Navigation to different rooms during non-emergency situations

Technology Stack

• Angular - for web app
• Ionic - for mobile app, also uses Angular
• Express JS - for API and websocket server
• FastAPI - for image processing and simulation server
• OpenCV - image processing for uploaded maps
• Firebase Realtime Database
• HM10 and ESP32 Bluetooth Low Energy module: for the BLE Beacons

Code structure

• orange-ecc: Ionic-Angular mobile app, also includes the web interface.
• server: backend servers
  • command-center-api: includes map image processing, pathfinding, simulator and beacon estimator.
  • ws-api: WebSocket server for realtime location updates
• analysis: some basic analysis of iBeacon sensor data
