The second control unit, during for the standby signal that is load when the state information of described load, the energy size that is transmitted to receiving terminal is adjusted to the minimum value that maintains the required electric energy of corresponding load stand-by operation by transmitting terminal;
The 3rd control unit, for being that power adds or when power cut signal, transmitting terminal correspondingly increases energy transmitting power or reduces energy transmitting power when the state information of described load;
The 4th control unit, in the time that the state information of described load comprises rapid adjustment signal, transmitting terminal correspondingly strengthens the step-length of Modulating Power, to reduce the time of Modulating Power.
