根据消毒碗柜的温度控制要求,设计了输出控制电路及不需要插值、查表的温度采集输入电路,并给出了软件系统的设计思想。虽然在设计中将不是线性关系的温度与热敏电阻值看成线性关系,但是试验证明在小的温度控制范围内1%误差还是可以接受的。 According to the temperature control requirements of the disinfection cupboard, the output control circuit and the temperature acquisition input circuit without interpolation and look-up table are designed, and the design idea of ​​the software system is given. Although the relationship between temperature and thermistor values ​​that are not linear in the design is seen as a linear relationship, experiments have shown that a 1% error is acceptable over a small temperature control range.
