The Design of Solar Water Heater Control System Based on PLC
Abstract: This study is the application of the programmable controller in the control system of solar water heaters. Discuss A solar water heater control system hardware configuration and software design. Proposed an important indicator of the programmable controller design is to meet the various functions of automatic control. And taking into account the feasibility of solar water heaters, hardware maintenance, software systems can be controlled. Solar water heaters, draw a process flow diagram of the present system, the selection of the I / O point is assigned and hardware; draw solar water heater according to the design requirements of the corresponding ladder. Completed the design of the automatic cotrol system of solar water heater.
Keywords: PLC; Solar water heaters; Automatic control system
