Development of the automated workstation for the operator of the solid municipal wastes landfill

Abstract

Abstract An automated workstation for the operator of the Solid Municipal Waste Landfill was developed on the example of the Solid Municipal Waste landfill in Nytvensky District, Perm Region. The most important task is to automate the accounting of incoming waste for disposal at the Solid Municipal Waste landfill. The system includes wheel-load scales, video locking system, recognition module and database management system. The database management system generates reports of three types: for landfills, for organizations removing waste from residential areas and infrastructure facilities, and for emission flows (leachate and LFG). The developed database management system is intended for accounting of incoming wastes to landfills. In the future, this database will serve as the main one for keeping records of emissions, creating reports on landfill workloads and their filling dynamics. A diagram of states and transitions of operator`s automated workstation was built. The logical equations describing the algorithm of equipment operation are developed. The ladder program for programming the logic controller is based on the international standard IEC 61131-3. A block diagram of an algorithm for solving the task of automated monitoring of processes at the Solid Municipal Waste range, aimed at preventing emissions from getting into the environment, has been proposed. The Omron SYSMAC CP1L controller and NT21 touch screen were chosen as hardware and software. The automated workstation developed for the landfill operator will improve the quality and productivity of the landfill controller and generate reports in both text and graphic form, with their transmission to environmental organizations.
