A system for surveillance of, and taking measures in respect of, phenomena that are observable. The system comprises at least one information centre (110) with associated cells (130-139) that can be divided into one or more groups. The system also comprises means for communication (120, 250) between an information centre and each cell. Each cell comprises at least one sensor (270, 271), with which chemical or physical measuring methods can be used to observe the phenomenon or detect the signals which the phenomenon generates/emits. This system further comprises at least three cells that are distributed geographically in the area of interest in a sufficiently dense net. In the cells the signals can be used for determining for example the time, place, intensity or the type of the phenomenon. Data can be transferred from the cells to their respective information centre for processing. Activities can be initiated and carried out by equipment inside or outside the cells in accordance with rules in the cells, and these activities can be started as a response to the detected signals. <IMAGE> |
