Abstract
A process for the elimination of thermal interferences in the infrared and video fire detection at an early stage in waste incineration plants, recycling facilities, warehouses and the like. The process is characterized by an additional noise and vibration analysis, by measuring the noise level of vehicles situated in the area to be detected or other thermal interference sources, with a distinction in measuring the noise level between day mode and night mode. The volume thresholds can thus be determined and be used as a threshold for determining whether a fire extinguishing sequence should be triggered.

A method for eliminating thermal interferences in infrared and video fire detection at an early stage in waste incineration plants, recycling facilities and warehouses, via a detection system that detects heat sources, comprising the steps:
- detecting noise and vibration via measuring equipment, wherein the measuring equipment also measures the noise level and the noises and the vibrations of vehicles and other sources of thermal interference in the area to be detected, said vibrations of vehicles and other sources of thermal interference being filtered out and recognized for differentiation in an analysis, analyzing the noise and the vibration detected via the measuring equipment, the measuring equipment being connected to a processing unit, the processing unit including a memory device for storing noise and vibration data and distinguishing between permissible heat sources and impermissible heat sources by means of an analysis device based on the noise and the vibration data and the infrared and the video data.
A device for eliminating thermal interference for infrared and video-based early fire detection in waste incineration plants, recycling facilities, warehouses, via a detection system that detects heat sources, comprising a noise and vibration analysis device integrated into the processing unit to which measuring equipment coupled to the processing unit is allocated for measuring noise and vibrations, wherein the measuring equipment also measures the noise level and the noises and the vibrations of vehicles and other sources of thermal interference in the area to be detected, said vibrations of vehicles and other sources of thermal interference being filtered out and recognized for differentiation in an analysis, the processing unit including a memory device for storing the noise data and the vibration data and distinguishing between permissible heat sources and impermissible heat sources via an analysis device integrated into the processing unit based on the noise and vibration analysis and the infrared and the video data.
