基于AT89C52的太阳能热水器智能控制系统设计

The Design of Solar Energy Heater Intelligent Controller

本文设计了一种以AT89C52为核心的太阳能集热智能控制系统,采用振荡器测水位,改进了压力传感器测水位的缺点,采用DS18B20替代负阻传感器。其水位显示、温度显示、温度控制、自动上水、手动上水、电加热、根据昼夜变化控制上水等功能都通过AT89C52直接控制。与传统的太阳能集热智能控制系统相比,本设计性价比和稳定性更高,应有一定的实用前景。

This thesis has designed anintelligent control system of solar-energy collection which takesSingie-chip AT89C52 as the core, andit elaborates the technical processing in the process of sofrware and hardware design. The realization of its all functions is directly controlled by the monolithic integrated circuit. The simulation results indicate that the intelligent control system has many functions, such as the water level display, the temperature display, the tempera ture control , auto-pouring watee, the electric heating COntrolling the water-ouring accOrdingto the diurnal variation and soon. compared with the traditrol control system, this thesis is higher in performance-to-price ratio and stability, therefore ithas a certain theoretical significance and the practicalprospect.
