Beschreibung:
<jats:p>The paper presents a system for automatic prevention of raising of ashes from
dedicated landfills based on a simple mathematical model which has modest
entry requirements for meteorological data. Such an approach is efficient
enough and enables fast information retrieval, i.e. zones with different
concentrations of dust in the air, enabling quick start of counter measures
to reduce emissions of ashes into the air. The system hardware consists of
an automatic weather station, set of meters that determine moisture of ash,
set of remotely managed sprinklers, computers, microprocessor and
microcontroller based elements for the local acquisition and management of
the executive elements and modules for wireless data transfer. An original
software application for the system management has been developed. Within
the application there is a module that allows entering of all data necessary
to configure the system, as well as data about sensors and sprinklers. Based
on the meteorological input data, measured moisture content of the ashes,
and on the basis of determined functional dependencies, special software
module operates sprinklers for soaking the surfaces from which the ashes is
emitted into the air, in order to eliminate these emissions. The system,
based on the developed mathematical model, predicts the propagation of ashes
through the air, as well as dry and wet deposition, in real-time. The system
automatically stores all the data relevant to the future analyses and
reporting. The system is designed and implemented as modular and open. A
custom developed graphical user interface serves as Man-Machine Interface
(MMI). By using the TCP/IP connection it could be easily connected with the
other information systems.</jats:p>
