Quickly adjustment, length 1bit, indicate notice transmitting terminal increase adjustment power step-length, with reduce adjustment power when
Between；
Check code, length 1bit, for being verified to the status information.
8. system according to claim 5, which is characterized in that the control module of the transmitting terminal specifically includes：
First control unit, for when the status information of the load is the off signal of load, transmitting terminal to turn off energy
Transmission；
Second control unit, for when the status information of the load is the standby signal of load, transmitting terminal will to be transmitted to and connect
The energy size of receiving end is adjusted to maintain the minimum value of electric energy needed for corresponding load stand-by operation；
Third control unit, for when the status information of the load is that power adds or when power cut signal, transmitting terminal is correspondingly
Increase energy transmitting power or reduces energy transmitting power；
4th control unit, for when the status information of the load includes quickly adjustment signal, transmitting terminal correspondingly to increase
The step-length for adjusting power, to reduce the time of adjustment power.
