本文给出了基于单片机控制的温度连续可调的冷热杯的总体框图。分析了以单片机AT89C2051为核心,用单总线温度传感器18B20进行温度采集,控制半导体制冷片作制冷或加热器件,对杯中的水或者罐中的饮料等进行快速加热或急冻。通过轻触按键,对温度进行连续可调设置,有LCD同步显示,设有制冷与加热状态指示灯显示本机工作状态,控温精度±1℃,可完全满足不同人的需求。
In this paper, based on the single chip microcomputer control the temperature continuously adjustable hot and cold cup overall block diagram. The single chip AT89C2051 is taken as the core and the single bus temperature sensor 18B20 is used to collect the temperature. The semiconductor cooling chip is controlled for cooling or heating, and the water in the cup or the beverage in the canister is rapidly heated or frozen. Through the touch of a button, the temperature continuously adjustable settings, LCD display simultaneously, with a cooling and heating status indicator shows the working status of the machine, temperature control accuracy ± 1 ℃, can fully meet the needs of different people.
