gas detection system for the detection of toxic and / or explosive gas mixtures in closed rooms with a speech output unit for the acoustic signaling

摘要

gas detection system (6) for detecting toxic and / or explosive gas mixtures, comprising at least one gas sensor (1) and a number of further sensors (2) for detecting environmental influences at the point of installation of the gas detection system (6) as well as a speech output unit (7, 8) for the acoustic signaling, wherein the gas detection system (6) the information of the at least one gas sensor (1) and information of at least some of the further sensors (2) is detected and evaluated with respect to their temporal variation, from the time change of individual of this information and / or the combination of at least several of these information are present in each case, the more probable environment states at the point of installation of the gas detection system (6) and the existing and / or future which is (14, 14 '') is determined, and, in a function of the determined alarm situation (14, 14'') the speech output unit (7) in such a way that the alarm situation (14, 14 '') adapted for speech information in the region of the persons located gas detection system (6) are audible, wherein the gas detection system (6) a time change of signals of the sensors (2) for detecting possible equipment manipulation as information on the type and..
