Integration of Human Evacuation Route Optimization Model and Fire Prevention and Control System

Abstract

Traditional evacuation induction system is unidirectional and unchangeable, directing to the nearer egress without any change considering the dynamic spread of fire scene. Intelligent evacuation induction system aims at dynamically directing to the safest and most efficient evacuate route far from fire sources, which improves the traditional and passive evacuation idea to active idea. Some intelligent evacuation induction systems have been developed in-and-abroad. However, they can simply realize the function of two-way directional evacuation on the level of local evacuation safety. To achieve real intelligent evacuation on the level of global evacuation safety, a linkage control is realized based on the integration of Human Evacuation Route Optimization Model (HEROM) and the Fire Prevention and Joint Control System (FPJCS). A new intelligent evacuation induction system is established and a case study is illustrated in this poster. It is established on the basis of information distribution between fire spreading scenario and the action status of fire prevention and control facilities in building. Based on dynamic relationship database technology, data transfer is realized between AACA based HEROM and FPJCS. The optimized evacuation route database of building is updated dynamically and timely with consideration of the fire spread scenario. For example, once a fire shutter blocked an evacuation corridor, the ever safe egress became inaccessible, the optimized evacuation route is updated and saved in an order file, the accessibility information of relevant node is recorded and transferred to change the induction direction of the evacuation signs.
