IOT based Intelligence for Fire Emergency Response
- 2. Abstract: Modern buildings around the world have become complex and augmented. Given the structural characteristics of modern buildings, quick evacuation using emergency exits or evacuee guidance markers during blackouts due to fire, building collapse, earthquakes, or aging of buildings need to be possible. This paper suggests an Internet of Things(IoT)-based intelligent fire emergency response system that can control directional guidance intelligently according to the time and location of a disaster and the design of an integrated control system using wireless sensor networks to address the problems with existing fire emergency response systems in times of fire or building collapse.

I.Introduction: • This paper suggests an IoT-based intelligent fire emergency response system with decentralized control that can intelligently guide evacuees based on the location and time of a fire to minimize the loss of human life. •Taking more than 20 minutes to evacuate from a fire, which is one of the most frequent disasters, greatly reduces survivability. •Uniform evacuation guidance such as exit lights are inadequate for guiding evacuees during a fire, which can create poisonous gases, or when buildings are collapsing. •Existing emergency exit guides do not consider the location of the fire and merely direct people to the nearest exit, this may create significant secondary casualties if a fire has occurred at the exit and the evacuees are guided towards it.

- 10. 2.2 Wireless Sensor Network (WSN) The network is composed of dispersed sensor nodes that measure the physical and environmental conditions such as the temperature and pressure, gateways that collect information from the nodes wirelessly and relay the information to the central server, and user interface software for storing, managing, analyzing, and utilizing the collected information. As shown in Figure 1, ZigBee is generally used for wireless communication between sensor nodes. The observed data are relayed to the gateway through flooding. Figure 1.

- 23. IV. Conclusion The proposed IoT-based intelligent fire emergency response system can reduce casualties by determining the point of occurrence of a disaster in a building to prevent directional confusion of the emergency lights and inappropriate evacuation guidance. The intelligent emergency evacuation system can also aid firefighting because it allows for a quick assessment of the exact location of the fire by integrating the intelligent and automated evacuation system with the central national emergency management agency. It reduces casualties and the time required for evacuation by guiding evacuees into dispersed detours that bypass the location of the fire. Future studies will focus on expanding the applicability of this system to not only building disasters, but also various fields such as ocean vessels and evacuation within buildings, disaster safety through Web or mobile application services, and preventive actions for optimal disaster recovery.
