The electric power conditioning device, connected to an apparatus and an electric storage device in a house, comprises an electric power receiving section, a communication section and an operation section. The electric power receiving section, connected to a commercial power supply, acquires a total electric power consumption amount of the commercial power supply. The operation section makes comparison as to whether an integrated value obtained by integrating the total electric power consumption amount and an electric power consumption amount which is an amount of electric power expected to be consumed when the apparatus is operated exceeds a predetermined value. When the integrated value does not exceed, the operation section transmits a use permission signal to the apparatus via the communication section. When the integrated value exceeds, the electric power conditioning device transmits to the electric storage device a supply electric power inquiring signal via the communication section.

The radio communication device offers data communication with no adverse effect of EMI radiation. In response to EMI radiation detected by the radiation detector, the controller changes the normal communication mode into the avoidance communication mode. In the avoidance communication mode, the transmitter prepares a transmission packet so as to satisfy the following relational expressions: T1=T0/2/M and T2=T0/2 (where, T0 represents the cycle of an AC power source; T1 represents the transmission time; and T2 represents the transmission cycle). The transmission power changer determines the transmission power by multiplying T2/T1 to the transmission power in the normal communication mode. The transmission rate changer determines the transmission rate by multiplying T2/T1 to the transmission rate in the normal communication mode. The transmission packet is transmitted in synchronization with the stopping time of EMI radiation detected by the timing detector.

Provided are an apparatus control device and an apparatus control method that make it possible to improve convenience for the user. An apparatus control device includes: a time-shift time computation unit that computes a time-shift time indicating an operation start time or an operation end time at which an electricity cost billed when an electric apparatus is operated is equal to or less than a predetermined rate, a recomputation determination unit that determines whether or not to change the time-shift time computed by the time-shift time computation unit, and a notification unit that, when determination is made by the recomputation determination unit that the time-shift time is to be changed, notifies the user that the initially computed time-shift time is to be changed.
