基于单片机的电热水器热水预测与控制系统

Hot Water Prediction and Control System of Electric Water Heater Based on Single Chip Microcomputer

针对智能储水式电热水器对未来热水用量的预测和控制需求,基于单片机的热水预测-控制系统以单片机为核心预测用户未来用水需求,并控制电热水器供应目标热水量。硬件上,温度和流量传感器检测并记录用户用水,继电器是控制电热水器加热的关键器件。软件程序上,主要通过最小二乘法对用户用水的时间序列数据找出用户用水规律,并根据用水周期预测未来的用水量需求,最后控制电热水器加热内胆冷水到目标温度。

Aiming at the prediction and control demand of intelligent water storage electric water heater for the future hot water consumption,the hot water prediction control system hased on single-chip microcomputer uses single-chip microcomputer as the core to predict the future water demand of users and control the target hot water supply of the electric water heater.In terms of hardware,the temperature and flow sensors detect and record the user's water consumption,and the relay is the key device to control the heating of the electrie water heater.In terms of software program,the least square method is mainly used to find out the user’8 water use law from the time series dala of user water use.predict the future water demand according to the water use cyele,and finally control the electric water heater to heat the cold water in the tank to the target temperature.
