针对目前老年人卫浴产品温度无法智能控制或一直存在控制精度低、耗时长的问题,提出基于物联网的老年人卫浴产品温度自动控制方法.建立老年人卫浴产品控制模型并分析各参数对控制效果的影响,采用最小二乘法对老年人卫浴产品控制模型结构参数进行估计,在此基础上,采用多变量广义预测控制简化算法对模型结构进行辨识,确定水温变冷的速度,采用物联网对老年人卫浴产品温度自动控制方法进行改进处理.实验结果表明,采用改进控制方法时,其温度控制精度、控制所需时间均要优于传统的控制方法,具有一定的优势.%Since the temperature of the elderly sanitary product can′t be controlled intelligently,and the temperature con-trol has low precision and long time consumption,an Internet of Things(IoT)based temperature automatic control method of el-derly sanitary product is proposed. The control model of the elderly sanitary product was established,and the influence of each parameter on control effect is analyzed. The least square method is used to estimate the structure parameter of the elderly sani-tary product control model. On this basis,the multivariable generalized predictive control simplified algorithm is used to identify the model structure,and determine the cooling speed of water temperature. The IoT is adopted to improve the temperature auto-matic control method of elderly sanitary product. The experimental results show that,in comparison with traditional control methods,the improved temperature control method has higher control precision and shorter control time,and has a certain advantage.
