Intelligent water temperature control system and method

Abstract

The invention discloses an intelligent water temperature control system, which comprises a temperature measurement module, an infrared remote control module, a sound production module, a display module and a single chip microcomputer, wherein the temperature measurement module is used for monitoring water temperature in real time and acquiring real-time water temperature Tg; the infrared remote control module is used for setting target water temperature Tw which needs to arrive at in a remote control mode; the sound production module is used for producing a sound for prompting when the target water temperature Tw is set successfully; the display module is used for displaying the real-time water temperature Tg and the target water temperature Tw; and the single chip microcomputer is used for acquiring a water temperature difference value e=Tw-Tg and a difference value change rate ec=de / dt according to the real-time water temperature Tg and the target water temperature Tw, comparing an absolute value |e| for the water temperature difference value and a preset threshold e0, adopting a Bang-Bang variable structure control method to carry out control heating on a heating module via a temperature control module when |e|> / =e0, and adopting an adaptive PID control-based PWM control method to carry out control heating on the heating module via the temperature control module when |e|<e0 to enable the water temperature to reach the target water temperature Tw finally. The invention also discloses an intelligent water temperature control method. Accuracy and stability are improved.
