PLC-Based Systems for Data Acquisition and Supervisory Control of Environment-Friendly Energy-Saving Technologies

Abstract

This paper presents the development of PLC-based systems for data acquisition and supervisory control of environment-friendly energy-saving complex high-tech technologies. The functional structure and main components of PLC-based SCADA-systems for environment-friendly energy-saving technological processes are given. The examples of SCADA applications in design of PLC-based systems for monitoring and automatic control of (a) ecopyrogenesis (EPG) and (b) thermoacoustic technological processes are presented. Paper considers the criteria of energy and economic efficiency of the EPG technological process. The functional structures, software and hardware implementation as well as multi-level human-machine interfaces of the developed PLC-based systems for data acquisition and supervisory control are given. Considerable attention is given to particular qualities of computing of ecopyrogenesis and thermoacoustic processes technological parameters by the proposed SCADA-systems. The developed PLC-based SCADA-systems provide: significant increasing of energy and economic efficiency criteria of the EPG and TAD complexes, high precision control of both technological processes, monitoring of current technological parameters, using the indirect methods for parameters measuring and identifying, and automatic control with high quality indicators and optimal parameters.
