Research of Remote Monitoring and Control System of Energy Saving Control Station Based on PLC and KingView

Three-phase asynchronous motors are main energy consumption devices of freezing station of sinking with freezing method.How to control consumption of sinking with freezing method and save its cost efficiently is a problem. To solve the problem, the paper proposed a design scheme of remote monitoring and control system of energy saving control station based on PLC and KingView, and introduced hardware configuration and software design of the system. The system adopts PLC as local real-time control system, which makes use of output of a frequency converter to control rotation rate of motors effectively so as to save energy. Meantime, the system uses KingView software to construct connection with field sensing devices and draw pictures to complete remote monitoring of energy saving control station.
