Research and Design of Solar Water Heating System Controller

控制器以Atmega169芯片为核心,采用模块化方式进行系统软硬件的设计,对系统所需的多路温度信号采集及调理电路进行深入的分析.提出了三种温度控制算法,在对各种算法分析研究的基础上结合供热模型进行Matlab/simulink仿真和实验研究对比分析,确定供热系统的控制算法.经过测试,整个控制器低功耗、设计简便、功能完善、实际控制效果良好.

Controller takes Atmega169 chip as the core, uses a modular approach to system software and hardware design, and analyzes muhi - channel tamperature signal acquisition and conditioning circuit required by the system. Three temperature control algorithms are proposed. Based on the analysis and research of various al- gorithms combined with heating model, the Matlab / simulink simulation and experimental studies are compared and analyzed to determine the heating system control algorithms. After testing, it is found that the entire control- ler has low power consumption, simple design, complete functions and good practical control.
