Comprise the radiant type radio energy transmission system of receiving terminal; The state of described receiving terminal comprises: idle condition, ready state, identification and configuration status, connection status and energy acceptance state;
In a charging cycle, the process of receiving-end state conversion is as follows: be in idle condition when receiving terminal electricity is sufficient, does not respond the broadcast that transmitting terminal sends under this state; If detect that receiving terminal is electricity lower than during threshold value or when user initiatively initiates charge request, receiving terminal enters ready state; When having inquiry if receive after entering ready state the need of the broadcast of charging, receiving terminal then makes response to this broadcast, and transfers identification and configuration status to; After receiving terminal and transmitting terminal complete and identify and configure, enter connection status; Afterwards, transfer energy acceptance state to, receive the energy of transmitting terminal transmission, after receiving terminal charging, come back to idle condition.
6. method according to claim 5, is characterized in that, the process that enters of described idle condition also comprises:
Under energy acceptance state, receiving terminal loses the connection with transmitting terminal, comes back to idle condition.
7. method according to claim 5, is characterized in that, receiving terminal and transmitting terminal identification layoutprocedure comprise:
Identify that, with under configuration status, receiving terminal and transmitting terminal, by information interaction, carry out identification and the certification of identity, if identify configuration successful, then transfer connection status to, if identify configuration failure, then transfer idle condition to.
8. method according to claim 5, is characterized in that, connection status and energy acceptance state comprise:
During connection status, receiving terminal and transmitting terminal have identified and configuration successful, but also do not carry out the transmission of energy; In this condition, the parameter of receiving terminal and the further synchronous energy of transmitting terminal and data transmit-receive, comprises setting Energy Transfer power window parameters;
In energy acceptance state, receiving terminal and transmitting terminal carry out the transmission of energy, and receiving terminal is periodically to transmitting terminal feedback information, and the parameter that transmitting terminal transmits according to feedack adjusting energy, meets receiving terminal parameter requirements;
Connection status and energy acceptance state conversion process as follows: under energy acceptance state, system charging complete, then receive stop energy acceptance, enter connection status; Under energy acceptance state, if there is exception error, then transmitting terminal stops Energy Transfer, and receiving terminal gets back to connection status, after waiting debug, reenters energy acceptance state; Under energy acceptance state, if receiving terminal generation parameter change, need and transmitting terminal match parameter again, system stops Energy Transfer, and receiving terminal gets back to connection status; Under energy acceptance state, receiving terminal loses the connection with transmitting terminal, and receiving terminal transfers connection status to;
The process that connection status proceeds to other states also comprises: under connection status, and the connection of receiving terminal and transmitting terminal is lost, and receiving terminal gets back to ready state; Under energy acceptance state, if receiving terminal generation parameter change, need and transmitting terminal match parameter again, system stops Energy Transfer, and receiving terminal gets back to connection status, enters identification subsequently and reshuffles with configuration status; System charging is complete, and transmitting terminal stops the transmission of energy, enters connection status, then transfers idle condition to by connection status.
9. the definition of reciprocal process state and a conversion method in radiant type radio energy transmission system, is characterized in that, comprising:
Comprise the radiant type radio energy transmission system of transmitting terminal and receiving terminal; The state of described transmitting terminal comprises: idle condition, notify status, identification and configuration status, connection status and Energy Transfer state; The state of described receiving terminal comprises: idle condition, ready state, identification and configuration status, connection status and energy acceptance state;
The process that in a charging cycle, transmitting terminal and receiving-end state are changed is as follows:
When initial condition, transmitting terminal is in idle condition, and it will periodically outwards send broadcast thus enter notify status;
Receiving terminal electricity is in idle condition time sufficient, does not respond the broadcast that transmitting terminal sends under this state; If detect that receiving terminal is that electricity is lower than during threshold value or when user initiatively initiates charge request, receiving terminal enters ready state, when there is inquiry the need of the broadcast of charging if receive after entering ready state, receiving terminal then makes response to this broadcast, and transfers identification and configuration status to;
When transmitting terminal receives the response message of receiving terminal, then transfer identification and configuration status to; After receiving terminal and transmitting terminal complete and identify and configure, transmitting terminal and receiving terminal all enter connection status;
Afterwards, transmitting terminal transfers Energy Transfer state to, and receiving terminal transfers energy acceptance state to, and meanwhile, transmitting terminal carries out Energy Transfer to receiving terminal; After receiving terminal charging, transmitting terminal and receiving terminal all enter idle condition.
