The invention discloses a household intelligent anti-theft electricity-saving system. The system mainly comprises a center processor, a WIFI receiving module, a button control module, a distance detection module, an infrared device, a terminal display module, an alarm module and a time control module. According to the household intelligent anti-theft electricity-saving system, units and the modules are connected with a center control unit in different directions, the adopted units and the adopted modules are simple, the number of components is small, the overall structure is very simple, value accuracy of a current sampling unit and a voltage sampling unit is guaranteed when electricity enters the current sampling unit and the voltage sampling unit, the situation that targeted and effective adjustment cannot be carried out later is avoided, and the electricity-saving effect is improved; currents and voltage are adjusted step by step by means of an analog speed-adjustment unit, a digital speed-adjustment unit and an actuator module, so that stability during adjustment is guaranteed and operation precision is improved; a detection unit and a protection unit guarantee the effectiveness of adjusted values and safety performance.
