摘　　要：文章提出了一种基于PID控制算法的恒温控制器,满足了用户对舒适泡澡体验的需求,提高了恒温澡盆的智能化和便携性。文章设计了闭环恒温控制器热导信号的采集、放大、滤波以及温度闭环控制等环节;根据所采集的温度数据,设计比例、积分、微分参数,计算目标温度与实际温度之间差值,调节恒温控制器的参数以获得最优的加热方式。实验结果表明,该恒温控制器能够将最终温度误差控制在±0.1℃,提高了水温的加热效率,实现了更精确的温度控制效果。In this paper,a thermostatic controller based on PID control algorithm is proposed,which meets the user’s demand for a comfortable bathing experience and improves the intelligence and portability of the thermostatic bathtub.The acquisition,amplification,filtering and temperature closed-loop control of thermal conductivity signals of the closed-loop thermostatic controller are designed in this paper.According to the collected temperature data,the proportional,integral and derivative parameters are designed,the different value between the target temperature and the actual temperature is calculated,and the parameters of the thermostatic controller are adjusted to obtain the optimal heating mode.The experimental results show that the designed thermostatic controller can control the final temperature error at the range of±0.1℃,improve the heating efficiency of water temperature,and achieve more accurate temperature control effect.
