US 2003/0146823 A1 · System and an arrangement to determine the positon in a hazardous situation

Abstract

The present invention relates to a system and to an arrangement for evaluating in a defined space or area a delimited area (7) in which there is a degree of urgency greater than the degree of urgency in respect of the remainder of said space (1), wherein there is disposed within said space or area (1) a plurality of sensors which can evaluate the current or ongoing degree of urgency on the basis of one or more criteria. Selected sensors (2, 3, 4) shall be connected to computer equipment (50) which includes storage elements (52, 53, 54) adapted for storing current criteria-related values in a chosen time order, and wherein a calculating circuit (51) included in or connected to said computer equipment (50) is adapted for evaluation of a calculated degree of urgency on the basis of time-dependent changes in the evaluated current values, and determining and establishing the local orientation or geographic location of the delimited area through the medium of the calculating circuit.

Dependent claims

A system for evaluating the development of a hazard situation within a space or an area with the aid of hazard level concepts and, upon the occurrence of a hazard situation, creating conditions whereby the hazard level of the hazard situation can be obtained on the basis of information relating to the development of said hazard situation deriving from a plurality of sensors that function in respect of mutually the same or mutually different criteria, characterised in that information relating to the time-wise variation of output signals related to the hazard situation and obtained from a first sensor and also relating to at least the time-wise variation of similar output signals obtained from a second sensor can be stored;

in that a comparison between the current or momentary values of the output signals and/or measured time-related changes generate a hazard level value for the occurring hazard situation through the medium of a calculating circuit;
and in that solely the hazard level values that exceed a first hazard level of an indicated hazard situation are chosen to follow the development of the hazard situation by means of the output signals from said sensors and to calculate the geographic location of the hazard.

An arrangement for evaluating the development of a hazard situation within a space or within an area with the aid of hazard level concepts, and for creating in the event of a hazardous situation conditions which enable the hazard level of said hazard situation to be determined on the basis of information concerning the development of said hazard situation and obtained from a plurality of sensors in respect of mutually the same or mutually different criteria, characterised in that information obtained concerning the time-wise variation of the output signals related to said hazard situation and delivered from a first sensor and at least the time-wise variation of similar output signals from a second sensor are storable in the memory;

in that a comparison between the current values of said output signals and/or measured time-related changes generate through the medium of a calculating circuit a hazard level value for the occurring hazard situation;
and in that solely the values that exceed a first hazard level of an indicated hazard situation are chosen in following the development of the hazard situation with the aid of the sensor output signals and calculating the geographical location of the hazard situation.
