Life became convenient thanks to the information infrastructure that had improved and developed. On the other hand, it is very weak at the disaster such as large earthquakes. Therefore, it is necessary to construct a strong network in the disaster. And also, the function to collect required information, such as an evacuation route and a fire situation, automatically according to a disaster situation is required. This paper proposes two techniques, the technique for conquering the down of the network link at the time of a calamity and the technique of collecting required information automatically according to the situation. This paper builds network intelligence by using these techniques to make the refuge support system at the time of a calamity, and shows the validity of this system by conducting a fire drill experiment.
