A Prototype for a Real-Time Indoor Evacuation Simulation System Using Indoor IR Sensor Information

摘要

Indoor fire simulators have been used to analyze building safety in the event of emergency evacuations. These applications are primarily focused on simulating evacuation behaviors for the purpose of checking building structural problems in normal time rather than in real time situations. Therefore, they have limitations in handling real-time evacuation events for the following reasons. First, the existing models mostly experiment with artificial situations using randomly generated evacuees, while the real world requires actual data. Second, the operation takes too long to generate real time data. Third, they do not produce optimal results for use in rescue or evacuation guidance. In order to overcome these limitations, we suggest a method to build an evacuation simulation system that can be used in real-world emergency situations. The system performs numerous simulations in advance according to varying distributions of occupants. Then the resulting data are stored in a DBMS. The actual data of people captured by an IR(infrared) sensor network are compared with the simulation data in the DBMS, and the queried data most closely is provided to the user. The system has been tested in a campus building, and the suggested processes are illustrated.
