Water heater regulating and control system based on radio frequency identification amplitude limiting detection circuit

Abstract

The invention discloses a water heater regulating and control system based on a radio frequency identification amplitude limiting detection circuit. The system comprises a microcontroller module, a cold water pipe electromagnetic valve, a hot water pipe electromagnetic valve, a temperature sensor, a flow sensor, a display unit and a keyboard input unit, wherein the cold water pipe electromagnetic valve, the hot water pipe electromagnetic valve, the temperature sensor, the flow sensor, the display unit and the keyboard input unit are connected with the microcontroller module. The microcontroller module comprises a comparison unit and a control unit. By the adoption of the system, the opening degrees of the hot water pipe electromagnetic valve and the cold water pipe electromagnetic valve are controlled through detection of the temperature and the water flow of a water mixing port, the flow is stabilized at a set value, and more importantly, the water outflow temperature is stabilized at a set value; and the problems that the temperature and the flow of water flowing out of a nozzle are changed suddenly are effectively solved, so that the constant-temperature water mixing function is achieved.
