摘要
传统电热水器系统大多采用单片机作为控制核心,仅具有加热和保温功能,水温不可见,水量不易控制,大多热水器在保温时采用开关控制,给电力系统带来巨大冲击。本系统选用现场可编程逻辑器件Actel Fusion系列FPGA作为控制核心,充分利用其内部模数混合的特点实现水温数字可视化、可预约时间等等功能,运用PID算法实现水的加热和保温,使电力系统受到很小的冲击,且该系统具有安全可靠、节能、高效能、性能稳定、简易操作的特性。
Most of traditional electric water heater adopts MCU as control core, and only have function of heating and thermal insulation. But the water temperature is not visible and water is difficult to control. Most of water heater adopts switch control when keeping temperature and have great impact on power system. The system adopts Actel Fusion FPGA as control core and makes full use of the characteristics of analogue-digital mixed to materialize these function, such as digital visualization, booking time and so on, and uses PID algorithm to finish water heating and thermal insulation, and brings small impact to power system. The system has characteristics of safety, energy-saving, high performance, stability and simple operation.
