【Abstract】 Frequency conversion constant pressure water supply system is a new type of high-rise building water supply with good water quality and pressure constant,reliable operation,high efficiency and energy saving advantages. In the context of energy shortage and national advocate for energy conservation and emission reduction,further research on constant-pressure frequency conversion water supply system has become one important research topic in the field of industrial automation control,particularly subject based on PLC control is often selected as graduation project for electrical engineering department of university. Through analysis and study students get basic characteristics and working principles of system and propose working well control solutions. Practice has proved that the researches on this topic will further enhance students’ professional capability of theory and practice.更多还原
