Method of fire detecting at a municipal solid waste landfill

Abstract

In the course of researching the anthropogenic danger of municipal solid waste landfills has been noted. The danger is due to the occurrence of surface and subsurface fires. Timely warning of the occurrence and spread of a fire depends on the definition of signs of combustion, not only on the surface, but also inside the body of the landfill. Existing methods of detecting information signs of a fire under adverse weather conditions or extreme conditions are characterized by low efficiency, reliability, completeness. The method of fire detecting at a municipal solid waste landfill has been proposed. It is realized by a thermal imaging camera, a video camera, a microwave radiometer arranged parallel to each other on a tower with the possibility of panoramic viewing. The results of the device observations under the different spectral bands of wavelengths in conjunction with the data of the angular-azimuthal axis direction meter arrive at the main server. Surveillance results of devices by overlaying and comparing are subject to filtering and elimination of thermal impediments. Exclusion of thermal barriers and the use of at least two observation points increase the likelihood of detecting combustion cells. Thus, the realization of this method will provide automatic detection of fire cells at their early as occurrence stage and informational support for management decision for localization and elimination of hazards with minimal impact on the environment and people.
