Wherein the information related to the transmitter may comprise at least one of: number information of the transmitter, location information of the transmitter, and other information related to the transmitter.

For the embodiment of the present application, it is assumed that the first preset time is 1s, and if the receiver does not receive the feedback signal within 1s after transmitting the composite signal, the receiver needs to determine the composite signal to be transmitted to the transmitter again, and transmit the determined composite signal to be transmitted to the transmitter. In this embodiment of the present application, the receiver determines that the composite signal to be transmitted to the transmitter at this time may be the same as or different from the composite signal transmitted last time, and is not limited in this embodiment of the present application.

In the embodiment of the present application, the composite signal transmitted each time may be the same as or different from the composite signal transmitted last time.

For the embodiment of the present application, assuming that the preset number of times is 4 times and the first preset time is 1s, if the receiver does not receive the feedback signal within 1s after transmitting the first composite signal 1 (for example, the composite signal 1 includes 100 sets of charging signals and 1 set of wake-up signals), it is determined that the composite signal transmitted next time is still the first transmitted composite signal, that is, the composite signal 1, and transmits the second composite signal 1, that is, the composite signal 1; if the feedback signal is not received within 1s after the second composite signal 1 is transmitted, determining that the composite signal transmitted next time is composite signal 2, where composite signal 2 is obtained by increasing the intensity of the charging signal and the like on the basis of composite signal 1 (for example, composite signal 2 includes 200 sets of charging signals and 1 set of wake-up signals), and transmitting composite signal 2 to the transmitter; if the feedback signal is not received within 1s after the composite signal 2 is transmitted, it is determined that the composite signal transmitted next time is the composite signal 3, the composite signal 3 is the composite signal 2 with the strength of the charging signal increased (for example, the composite signal 3 includes 300 sets of charging signals and 1 set of wake-up signals), and the composite signal 3 is transmitted to the transmitter.

Further, if the receiver receives the feedback signal within 1s after the receiver transmits the first composite signal last time, the receiver stops transmitting the composite signal; if the receiver receives the feedback signal within 1s after the receiver transmits the second composite signal last time, the receiver stops transmitting the composite signal; if the receiver receives the feedback signal within 1s after the last transmission of the third composite signal, the receiver stops transmitting the composite signal. That is, if the receiver receives the feedback signal within a first predetermined time after transmitting the composite signal, the transmission of the composite signal is stopped.

In the embodiment of the present application, the threshold of the number of times of the first composite signal may be input by a user, or may be preset, for example, the threshold of the number of times may be 3 times.

Specifically, if the number of times of transmitting the composite signal after the composite signal is transmitted in step S10131 does not reach the threshold number of times of transmitting the first composite signal (3 times), and the feedback signal transmitted by the transmitter is not received, that is, the composite signal to be transmitted is determined to be the first composite signal, and the first composite signal is transmitted to the transmitter until the third preset condition is met.

Wherein the third preset condition comprises: reaching a threshold number of times the first composite signal is transmitted and/or receiving a feedback signal transmitted by the transmitter.

Specifically, the third preset condition includes that the number of times that the receiver transmits the first composite signal reaches three times and/or the receiver receives a feedback signal transmitted by the transmitter; if the receiver transmits the first composite signal for the first time and does not receive the feedback signal transmitted by the transmitter, the receiver transmits the first composite signal for the second time; if the receiver transmits the second composite signal and does not receive the feedback signal transmitted by the transmitter, the receiver transmits the third composite signal, and if the receiver transmits the first composite signal for three times and does not receive the feedback signal or receives the feedback signal, the receiver stops circularly executing the steps of determining the composite signal to be transmitted as the first composite signal and transmitting the first composite signal to the transmitter.

S10133, if the threshold of the number of times of transmitting the first composite signal is reached and the feedback signal transmitted by the transmitter is not received, increasing the intensity of the charging signal in the previous composite signal and using the charging signal as the second composite signal, and performing the second composite signal transmitting step.

Specifically, a second composite signal transmission step is performed, comprising: determining the composite signal to be transmitted as a second composite signal, and transmitting the second composite signal to the transmitter; if the frequency threshold value of transmitting the second composite signal is not reached and the feedback signal transmitted by the transmitter is not received, the step of determining the composite signal to be transmitted as the second composite signal and transmitting the second composite signal to the transmitter is executed in a circulating mode until a fourth preset condition is met. In the embodiment of the present application, the fourth preset condition includes: reaching a threshold number of times the second composite signal is transmitted and/or receiving a feedback signal transmitted by the transmitter.

That is, if the threshold of the number of times of transmitting the first composite signal is reached and the feedback signal transmitted by the transmitter is not received, the second composite signal is determined and the second composite signal is transmitted, and if the threshold of the number of times of transmitting the second composite signal is not reached and the feedback signal transmitted by the transmitter is not received, the second composite signal determined this time is continuously transmitted until the threshold of the number of times of transmitting the second composite signal is reached and/or the feedback signal transmitted by the transmitter is received. In the embodiment of the present application, the intensity of the charging signal included in the second composite signal is greater than the intensity of the charging signal included in the first composite signal, for example, the second composite signal may include: 200 sets of charging signals and 1 set of wake-up signals.

For example, if the threshold of the number of times of transmitting the second composite signal this time is 2, if the threshold of the number of times of transmitting the first composite signal is reached and the feedback signal transmitted by the transmitter is not received, the intensity of the charging signal in the last composite signal is increased and used as the second composite signal, and the second composite signal is executed, and if the feedback signal is not received, it is determined that the composite signal to be transmitted is still the second composite signal, and the second composite signal is transmitted (200 sets of charging signals and 1 set of wake-up signals).

The following embodiment introduces the wireless charging method shown in the embodiment of the present application through a specific application scenario, which specifically includes: the transmitter is placed in the book, and the RFID chip in the transmitter writes the related information of the book in advance. The related information of the books includes the location area information (e.g., the first layer in the library) where the books are located and the identification information (e.g., the book numbers). The user uses the receiver to read the relevant information of the book. The receiver is preset with three sets of composite signal transmitting schemes through a processor, the transmitting times of the composite signals in each set of transmitting scheme are twice, the intensity of the charging signals in each set of composite signal transmitting scheme is different, one composite signal in the first set of transmitting scheme consists of one hundred groups of charging signals and one group of wake-up signals, one composite signal in the second set of transmitting scheme consists of two hundred groups of charging signals and one group of wake-up signals, and one composite signal in the third set of transmitting scheme consists of three hundred groups of charging signals and one group of wake-up signals.

When a user needs to acquire related information of a book, the user sends a charging instruction to a receiver, the receiver firstly sends a composite signal consisting of one hundred groups of charging signals and one group of awakening signals according to the charging instruction according to a first set of transmission scheme, a composite antenna on a transmitter receives the composite signal, and a voltage doubling shaping circuit on the transmitter converts the charging signal into electric energy and stores the electric energy into a power supply memory; when the voltage in the power supply memory in the emitter reaches the working voltage of the power supply manager, the power supply manager is awakened, and then the power supply manager detects whether the voltage in the power supply memory reaches the working voltage of the RFID chip; if the voltage in the power supply memory does not reach the working voltage of the RFID chip, the power supply manager and the RFID chip are both in a dormant state, if the receiver does not receive the feedback signal transmitted by the transmitter, the receiver continues to transmit a composite signal consisting of one hundred groups of charging signals and one group of awakening signals to the transmitter, and after the conversion process, the receiver does not receive the feedback signal, and stops transmitting the composite signal (the composite signal consisting of 100 groups of charging signals and 1 group of awakening signals). At this point the receiver starts the second set of transmission scheme;

the second set of transmission schemes: the receiver increases the number of groups of the charging signals in the first composite signal from one hundred groups to two hundred groups, so as to increase the strength of the charging signals, the receiver transmits the composite signal with the increased strength of the charging signals to the transmitter through the composite antenna,

and at the moment, the electric energy in the power supply memory is the electric energy of the charging signal in the first composite signal twice and the second composite signal once, if the voltage in the power supply memory reaches the working voltage of the RFID chip at the moment, the transmitter transmits the feedback signal through the composite antenna, and the receiver stops transmitting the second composite signal after receiving the feedback signal. If the voltage in the power supply memory does not reach the working voltage of the RFID chip at the moment, the power supply manager and the RFID chip are both continuously in a dormant state, and the RFID chip does not send a feedback signal; the receiver continuously transmits a composite signal (a composite signal consisting of two hundred groups of charging signals and a group of wake-up signals) which increases the strength of the charging signal; if the receiver still receives the feedback signal, the receiver starts a third set of transmission schemes.

The receiver increases the number of groups of the charging signals in the second composite signal from two hundred groups to three hundred groups to form a new composite signal, thereby increasing the strength of the charging signals. The receiver transmits the new composite signal (composite signal of three hundred sets of charging signals and 1 set of wake-up signals) to the transmitter via the composite antenna.

At this time, the electric energy in the power supply memory is the sum of the electric energy of the charging signal in the first composite signal twice, the second composite signal twice and the third composite signal once. If the voltage in the power supply memory reaches the working voltage of the RFID chip, the transmitter transmits a feedback signal through the composite antenna, and the receiver stops transmitting the composite signal (the composite signal consisting of three hundred groups of charging signals and 1 group of wake-up signals) after receiving the feedback signal. If the voltage in the power supply memory does not reach the working voltage of the RFID chip at the moment, the power supply manager and the RFID chip are both continuously in a dormant state, the RFID chip does not send a feedback signal, the receiver continuously transmits the new composite signal (the composite signal consisting of three hundred groups of charging signals and 1 group of awakening signals) to the transmitter, if the receiver still does not receive the feedback signal, the receiver stops transmitting the composite signal, and at the moment, the receiver judges that the transmitter fails through the processor.

If the transmission scheme is within the three sets of transmission schemes and the voltage in the power supply memory reaches the working voltage of the RFID chip, the power supply manager transmits the awakening signal to the RFID chip, the RFID chip generates a feedback signal according to the book related information in the RFID chip based on the awakening signal and transmits the feedback signal to the receiver through the composite antenna, after the composite antenna of the receiver receives the feedback signal, the RFID information processor in the receiver processes the received feedback signal, and the information after data processing is transmitted to the data center through the 4G wireless network transmitter. Such as transmitting the relevant location information, numbering status, etc. within the RFID chip to a designated data monitoring center.

After the transmitter sends the feedback signal, the power supply manager detects the voltage information in the current power supply memory again, generates a voltage signal according to the detected voltage information, and transmits the voltage signal through the composite antenna. After the composite antenna of the receiver receives the voltage signal, the processor processes the voltage signal and displays the voltage signal through the display screen. The user can conveniently know whether the power supply memory leaks electricity or not through the current voltage information of the emitter.

The receiver transmits a termination signal to the transmitter after receiving the voltage signal, and the transmitter places the power manager and the RFID chip in a dormant state after receiving the termination signal, so that the waste of electric energy caused by the fact that the power manager and the RFID chip are always in a working state when the electric energy of the power storage is sufficient is reduced.

For the embodiment of the application, the receiver comprises a common power supply, a battery and a standby power supply. The three have independent power supply function. The wireless charging device has the advantages that the transmitting power is high, long-time continuous work is needed, the power consumption is high, and a common power supply is directly used for being connected with commercial power to supply power on a use site. When the power failure condition occurs, the standby power supply can automatically deal with the accident condition and use the battery to supply power, so that the automatic access can be ensured under the condition of incapable normal power supply.
