CODE RED Environment Recognition and Safety Protocol for Firefighters S.Varun Vidhya Venkat Varsha C Satish Vijayakumar A

Problems The existing methods of determining the rapidly changing interior site conditions are time consuming and hazardous. Tool handling demands physical work and more access time. Finding an injured fire fighter amidst a fire is very difficult with the current radio communication system. Significant number of fighters die by breathing in toxic gases. Poor understanding of the site temperature conditions and fire progression.

Proposed Solution A smart connected helmet with a plethora of sensors to detect, an Augmented Reality projection system comprising an OLED to display, the interior conditions of temperature, gas concentration and the user’s own vitals.

Overall Architecture of Concept Prototype

Concept Prototype Sensing the site temperature to understand the moving path and fire progressing direction. ( Temperature sensor) Sensing the concentration of various toxic and non toxic gases for better understanding and to prevent death.(Gas sensor ) Monitoring the physiological status of the fighter by sensing heart rate. (Pulse Sensor) Accelerometers to detect potential attacks, injuries and trauma when a debris collides with the user’s head. The data from the sensors are overlayed on the vision of the user without obstructing the user’s vision. The raw data is sent to local cloud and transmitted to the nearest fighter when the other one is in danger.

Augmented Reality Based OLED Display

The Future System expansion by monitoring additional surrounding parameters. Adding a FLIR Thermal Imaging sensor to overlay a thermal image of the surroundings with normal vision. Integrating our system to the current emergency wireless network. The location of the downed fire fighters can be found using Trilateration to aid rescue.
