The design and implementation of early fire detection system

In Taiwan, according to the National Fire Agency, Ministry of the Interior, R.O.C, there are, on average, up to 5000 fire accidents per year, and many people die in fire accidents. An early fire detection system and an effective guidance system for fire evacuation can reduce fire casualties greatly. The purpose of this paper is to develop a system of early fire detection and evacuation navigation. The Science and Engineering Building at the Chaoyang University of Technology is used as the test building. We implement a fast and accurate system of early fire detection using a wireless sensor network as well as temperature alarms and smoke alarms. With an algorithm that involves temperature differences and information reported by individual sensors, this system can determine the optimal evacuation path in a very short period.
