Development of fire evacuation path selective using adaptive routing algorithms and RFID traffic cone-based observation with shadowing method

摘要

In this paper the Radio Frequency Identification (RFID) technology can be applied with the adaptive routings algorithms of fire evacuation paths selection and evaluation to inspect an efficiency of fire building protection system for fire evacuation monitoring report and fire protection system. The suitable path of all available fire evacuation paths in the building when fire explosion occurred is the main importance key not only for an efficiency of fire protection system management, but can be control the congestion situations, shortest evacuation time and safe for more life of all victims. The shortest path of all available fire evacuation paths are the first basically main criteria evaluation and second purposed is the real fire evacuation situation in this selective path that can be guarantee less congestion, safety and available path all time. The shortest path is computed by Dijkstra's algorithm and after that the weight of each connecting paths are updated by RFID traffic cone data based that are installed in each fire exit paths. The user with their RFID tags when passed in the fire evacuation paths are read by RFID traffic cone reader stations and send these data such as name, status, time arrival and other essential data to RFID data based via on Wi-Fi channel. In particular this paper is presented the shadowing model for estimating the indoor localizing with obstructed in building area of the RFID traffic cone stations that can be move to install along the all available fire evacuation paths easily. These RFID techniques can be deal with multi-users, multi-stations of RFID traffic cones and multi- fire evacuation paths. It provides an efficiency time management scheme with correct data reporting and can be work out in real time for fire protection system status. The data based is constructed for supporting to RFID tags of each fire protection product details, fire evacuation paths and can be mapping their localizing into the floor plan of the fire buil- ing automatically. Finally, the experiments are presented illustrating that the RFID traffic cone localization techniques may be improve for more accuracy estimation in real situation area while the fire evacuation path selection by shortest path algorithm can work well.
