Navigation system design of fire disaster evacuation path in buildings based on mobile terminals

To serve the emergency management for urban disaster prevention and mitigation, a spatial model for that will be established specific to the increasingly serious challenge on emergency evacuation in complex buildings, and an emergency evacuation platform is designed based on mobile GIS. The possible development tendency of events will be virtually derived by LBS positioning function and demonstration of spatial structure in the mobile terminal scene so that the dynamic routing of evacuation inside buildings can be designed. On the one hand, this research can provide data validation and decision ancillary support for virtual training and emergency rescue of urban disasters; on the other hand, it can also give some reference significances on completing emergency management system of public events and risk management system of jumbo risks.
