Research on electrical automatic control system based on PLC

Abstract At present, automatic control technology is widely used in the field of drying. Although existing processing can basically ensure quality drying, there are some problems, such as low production efficiency, thermal uneven hot air cloth, inaccurate temperature and so on. The application electromagnetic improve efficiency drying processing. It has remarkable energy-saving effect. In process, aiming at technical problems incomplete volatilization water difficult stability rapid a system based on PLC designed this paper. Using main controller system, through reasonable changes humidity more efficient process be realized. improved, flow mass Through experimental analysis it proved that accuracy research content paper accurate, which not only improves automation level but also reduces labor cost high value.
