Zusammenfassung:	The utility model provides a smart power grid power metering power stealing prevention control terminal. A direct current power supply unit is connected with an alternating current power supply. A relay (KM1) is connected in parallel with both ends of the power supply. An energy storage unit (E) is connected in parallel with both ends of the direct current power supply unit (U) through a normally open contact (KM1) of the relay (KM1). A remote control receiver is connected in parallel with both ends of the power supply. The remote control receiver is controlled by a remote control transmitter. A double winding magnetic keeping relay first winding (TQ1) is connected in series with a normally open contact (YK1) of the relay, which is used for remote control receiver reset control, and then is connected in parallel with both ends of the energy storage unit (E). A double winding magnetic keeping relay second winding (TQ2) is connected in series with a normally close contact (YK2) of the relay, which is used for r
