【 摘 要 】

The paper presents a system for automatic prevention of raising of ashes fromdedicated landfills based on a simple mathematical model which has modestentry requirements for meteorological data. Such an approach is efficientenough and enables fast information retrieval, i.e. zones with differentconcentrations of dust in the air, enabling quick start of counter measuresto reduce emissions of ashes into the air. The system hardware consists ofan automatic weather station, set of meters that determine moisture of ash,set of remotely managed sprinklers, computers, microprocessor andmicrocontroller based elements for the local acquisition and management ofthe executive elements and modules for wireless data transfer. An originalsoftware application for the system management has been developed. Withinthe application there is a module that allows entering of all data necessaryto configure the system, as well as data about sensors and sprinklers. Basedon the meteorological input data, measured moisture content of the ashes,and on the basis of determined functional dependencies, special softwaremodule operates sprinklers for soaking the surfaces from which the ashes isemitted into the air, in order to eliminate these emissions. The system,based on the developed mathematical model, predicts the propagation of ashesthrough the air, as well as dry and wet deposition, in real-time. The systemautomatically stores all the data relevant to the future analyses andreporting. The system is designed and implemented as modular and open. Acustom developed graphical user interface serves as Man-Machine Interface(MMI). By using the TCP/IP connection it could be easily connected with theother information systems.
