Referring to fig. 2, a flowchart of steps of a wireless power supply method of a communication device according to an embodiment of the present application is shown.

As shown in fig. 2, the wireless power supply method of the communication device may include the steps of:

in step 201, the communication device transmits a first probe signal after receiving an activation signal transmitted by the first device.

The first device will send an activation signal to the communication device when it needs to send information and cannot itself pass the information directly to the second device.

The activation signal is for example used to inform the communication device that the first device needs to send information to indicate that the communication device is activated. The activation signal may be a 1bit signal.

After receiving the activation signal transmitted by the first device, the communication device knows that the first device needs to send information, that is, needs to forward the information, and needs to provide power supply requirements for surrounding wireless power supply devices at the moment, so that the communication device transmits a first detection signal to the surrounding wireless power supply devices.

The first probe signal is for example used to inform the wireless power supply device that the communication device needs to be powered. The communication device may transmit a multi-bit first probe signal in the form of a broadcast to surrounding wireless power supply devices.

Step 202, after receiving first feedback signals transmitted by at least two first wireless power supply devices, the communication device selects a target first wireless power supply device from the at least two first wireless power supply devices based on the first feedback signals, and transmits a second feedback signal to the target first wireless power supply device.

For convenience of distinction, a wireless power supply device that receives a first detection signal transmitted by a communication device and returns a first feedback signal to the communication device in the embodiment of the present application is referred to as a first wireless power supply device. For any one of the first wireless power supply devices, after the first wireless power supply device receives the first detection signal transmitted by the communication device, the first wireless power supply device analyzes to know that the communication device needs to be powered, and at the moment, the first wireless power supply device transmits a first feedback signal to the communication device.

The first feedback signal is for example used to inform the communication device that the first wireless power supply device is capable of supplying power. The first feedback signal may be a 1bit signal.

The communication device may select a target first wireless power supply device from the at least two first wireless power supply devices based on the first feedback signals transmitted by the at least two first wireless power supply devices if the first feedback signals transmitted by the at least two first wireless power supply devices are received.

Referring to fig. 3, a process flow diagram of a target first wireless power supply device is shown.

As shown in fig. 3, the process flow of selecting the target first wireless power supply device may include the following steps:

in step 301, the communication device calculates redundancy coefficients of the first wireless power supply devices, and ranks the at least two first wireless power supply devices according to the sequence in which the first feedback signals are received.

For each first wireless power supply device, the communication device calculates redundancy coefficients of the first wireless power supply devices, respectively.

Illustratively, the first feedback signal may include, but is not limited to: a power threshold of the first wireless power supply device, a path loss power of the first wireless power supply device, a current load power of the first wireless power supply device, and so on.

Illustratively, the process of calculating the redundancy factor of the first wireless power supply device by the communication device may include: acquiring an operation power (actual operation power) of the communication device and a power loss of the communication device; the redundancy factor of the first wireless power supply device is calculated based on a power threshold of the first wireless power supply device, a path loss power of the first wireless power supply device, a current load power of the first wireless power supply device, an operating power of the communication device, and a power loss of the communication device.

Illustratively, the redundancy factor of the first wireless power supply device may be calculated based on the following formula:

P _th -(P _r +P _c +P _s )＝ηP _w

in the formula, eta represents the redundancy coefficient of the first wireless power supply equipment, P _th Representing a power threshold, P, of a first wireless power supply device _r Representing path loss power, P, of a first wireless power supply device _c Representing the current load power, P, of a first wireless power supply device _w Representing the operating power of a communication device, P _s Representing the power loss of the communication device.

And aiming at the at least two first wireless power supply devices, the communication device ranks the at least two first wireless power supply devices according to the sequence of the first feedback signals. The first wireless power supply equipment corresponding to the first feedback signal received earliest is arranged first, the first wireless power supply equipment corresponding to the first feedback signal received latest is arranged last, namely, the first wireless power supply equipment corresponding to the first feedback signal received first is arranged before, and the first wireless power supply equipment corresponding to the first feedback signal received after is arranged after.

Step 302, starting from the first wireless power supply device after sequencing, the communication device selects the first wireless power supply device meeting the preset conditions as the target first wireless power supply device, wherein the preset conditions comprise that the redundancy coefficient is greater than or equal to a preset threshold value and idle power supply antennas exist.

Starting from the first wireless power supply equipment after sequencing, the communication equipment judges whether the redundancy coefficient of the current first wireless power supply equipment is larger than or equal to a preset threshold value and whether an idle power supply antenna exists in the current first wireless power supply equipment; and determining the current first wireless power supply equipment as the target first wireless power supply equipment when the redundancy coefficient of the current first wireless power supply equipment is larger than or equal to the preset threshold value and the current first wireless power supply equipment has idle power supply antennas.

For example, the communication device orders the first wireless power supply device according to the sequence of receiving the first feedback signal transmitted by the first wireless power supply device, and then orders the first wireless power supply device into the first wireless power supply device a, the first wireless power supply device B and the first wireless power supply device C. If the redundancy coefficient of the first wireless power supply equipment A is larger than or equal to a preset threshold value and the first wireless power supply equipment has idle power supply antennas, the first wireless power supply equipment A is taken as a target first wireless power supply equipment; if the first wireless power supply equipment A does not meet the conditions, the first wireless power supply equipment B is continuously judged, and the method is performed in the same way until the target first wireless power supply equipment is selected.

The specific value of the preset threshold may be set according to practical experience, which is not limited in this embodiment.

For example, if the preset threshold is set to 1, the preset condition may be expressed as follows: eta is greater than or equal to 1, r is greater than or equal to 1, eta represents a redundancy coefficient, and r represents the number of idle power supply antennas. The set of redundancy coefficients of 1 or more for the first wireless power supply apparatus may be expressed as follows:

the target first wireless power supply device is used as a preferable wireless power supply device capable of supplying power to the communication device, and the communication device transmits a second feedback signal to the target first wireless power supply device after selecting the target first wireless power supply device.

The communication device may transmit a second feedback signal to a first wireless power supply device if it receives only a first feedback signal transmitted by the first wireless power supply device.

The second feedback signal is for example used to instruct the target first wireless power supply device to start powering. The second feedback signal may be a 1bit signal.

In step 203, after receiving a first power supply signal transmitted by the target first wireless power supply device, the communication device uses the first power supply signal to supply power to the communication device.

After receiving the second feedback signal transmitted by the communication device, the target first wireless power supply device knows that the communication device requests to start power supply, and can start power supply to the communication device at the moment, and the target first wireless power supply device transmits a first power supply signal to the communication device.

After receiving the first power supply signal transmitted by the target first wireless power supply device, the communication device can use the first power supply signal to supply power to the communication device, wherein the power supply is used for guaranteeing the normal operation of the communication device, such as receiving information, forwarding information and the like.

The first power supply signal may be an electromagnetic wave, for example, and may be any other form of power supply signal. After receiving the electromagnetic wave emitted by the target first wireless power supply device, the communication device can convert the electromagnetic wave into electric energy and provide the electric energy for the communication device.

Referring to fig. 4, a flowchart of steps of another wireless power supply method of a communication device according to an embodiment of the present application is shown.

As shown in fig. 4, the wireless power supply method of the communication device may include the steps of:

in step 401, after receiving an activation signal transmitted by the first device, the communication device switches from a sleep mode to a to-be-operated mode, and transmits a first probe signal.

The communication device will enter a sleep mode without receiving and forwarding information. In the sleep mode, the power consumption can be reduced, and power is not required to be supplied through the wireless power supply equipment, so that a power supply interface of the wireless power supply equipment is not occupied, and the environment-friendly low-carbon development is facilitated.

After receiving the activation signal transmitted by the first device, the communication device may switch from the sleep mode to the to-be-operated mode because of the need to prepare to receive and forward the information. In the pending mode of operation, the communication device will be ready to receive and forward information and perform step 402 described below.

In step 402, after receiving the first feedback signals transmitted by the at least two first wireless power supply devices, the communication device selects a target first wireless power supply device from the at least two first wireless power supply devices based on the first feedback signals, and transmits a second feedback signal to the target first wireless power supply device.

Step 403, after receiving the first power supply signal transmitted by the target first wireless power supply device, the communication device uses the first power supply signal to supply power to the communication device, and the to-be-operated mode is switched to the operation mode.

And the communication equipment is switched from the to-be-operated mode to the operation mode after being powered by the first power supply signal. In the operation mode, the communication equipment receives and forwards information normally.

Step 404, the communication device transmits a third feedback signal to the first device, the third feedback signal being used to instruct the first device to start sending information to the communication device.

And the communication equipment uses the first power supply signal to supply power to the communication equipment, and transmits a third feedback signal to the first equipment after the to-be-operated mode is switched to the operation mode.

The first device may begin transmitting information to the communication device after receiving the third feedback signal transmitted by the communication device. The communication device, upon receiving the information sent by the first device, may forward the information to the second device.

And step 405, if the communication device does not process information within the preset duration, transmitting a fourth feedback signal to the target first wireless power supply device, wherein the fourth feedback signal is used for indicating the target first wireless power supply device to disconnect power supply.

If the communication device does not process the information within the preset time, the communication device can inform the target first wireless power supply device of disconnecting the power supply. Specifically, the communication device transmits a fourth feedback signal to the target first wireless power supply device, the fourth feedback signal being used to instruct the target first wireless power supply device to disconnect power. The fourth feedback signal may be a 1bit signal, for example. The specific value of the preset time period may be set according to actual experience, which is not limited in this embodiment.

And after receiving the fourth feedback signal transmitted by the communication equipment, the target first wireless power supply equipment knows that the power supply needs to be disconnected, and stops transmitting the first power supply signal to the communication equipment. By the mode, the power supply can be disconnected in time when the communication equipment is relatively idle, so that electric energy can be saved.

In step 406, the communication device switches from the operation mode to the sleep mode after the target first wireless power supply device is powered off.

After the power supply of the target first wireless power supply equipment is disconnected, the communication equipment enters a sleep mode, so that the electric energy consumption is reduced, and occupation of a power supply interface of the wireless power supply equipment is avoided.

In the embodiment of the application, the dormant mode, the to-be-operated mode and the operation mode are set for the communication equipment, and the modes can be switched mutually.

Referring to fig. 5, a schematic diagram of a communication device operating mode of an embodiment of the present application is shown. As shown in fig. 5, the communication device may be switched from the sleep mode to the to-be-operated mode, from the to-be-operated mode to the operated mode, and from the operated mode to the sleep mode.

In an alternative embodiment, a capacitor may be provided inside the communication device, and the communication device may be powered by the capacitor inside the communication device in the sleep mode and/or the to-be-operated mode, because the communication device consumes less power in the sleep mode and the to-be-operated mode. For example, in the above-mentioned workflow, the process that the communication device transmits the first detection signal, the communication device transmits the second feedback signal, and the communication device selects the target first wireless power supply device may be powered by the internal capacitor.

In an alternative embodiment, the target first wireless power supply device will charge the capacitor when the communication device is in the operational mode, so as to wait for the next power supply use of the capacitor. Thus, the communication device may also charge the capacitor with the first power supply signal after receiving the first power supply signal transmitted by the target first wireless power supply device.

In an alternative embodiment, since the communication device is powered by the capacitor when in the sleep mode, the capacitor generates power consumption, so as to avoid the power consumption of the capacitor being low and influence the power supply, the capacitor can be charged in time according to the power condition of the capacitor in the sleep mode.

Referring to fig. 6, a process flow diagram of a communication device in sleep mode is shown in accordance with an embodiment of the present application.

As shown in fig. 6, the process flow of the communication device in the sleep mode may include the steps of:

in step 601, when the communication device is in the sleep mode and the power consumption of the capacitor reaches a preset proportion, the communication device is switched from the sleep mode to the to-be-operated mode, and transmits a second detection signal.

The specific value of the preset ratio may be set according to practical experience, and the embodiment is not limited thereto. For example, the preset ratio may be set to 50%, 60%, or the like.

When the communication equipment is in the dormant mode and the electric quantity consumption of the capacitor reaches a preset proportion, the dormant mode is switched to the to-be-operated mode, and a second detection signal is transmitted to surrounding wireless power supply equipment.

The second probe signal is used to inform the wireless power supply device that a capacitor inside the communication device needs to be charged, for example. The communication device may transmit a multi-bit second probe signal in the form of a broadcast to surrounding wireless power supply devices.

In step 602, after receiving the fifth feedback signals transmitted by the at least two second wireless power supply devices, the communication device selects a target second wireless power supply device from the at least two second wireless power supply devices based on the fifth feedback signals, and transmits a sixth feedback signal to the target second wireless power supply device.

For convenience of distinction, a wireless power supply device that receives a second detection signal transmitted by a communication device and returns a fifth feedback signal to the communication device in the embodiment of the present application is referred to as a second wireless power supply device. For any one of the second wireless power supply devices, after receiving the second detection signal transmitted by the communication device, the second wireless power supply device knows that a capacitor inside the communication device needs to be charged, and at this time, the second wireless power supply device transmits a fifth feedback signal to the communication device.

The fifth feedback signal is for example used to inform the communication device that the second wireless power supply device is capable of supplying power. The fifth feedback signal may be a 1bit signal.

The communication device may select a target second wireless power supply device from the at least two second wireless power supply devices based on the fifth feedback signals transmitted by the at least two second wireless power supply devices if the fifth feedback signals transmitted by the at least two second wireless power supply devices are received.

Illustratively, the process of selecting the target second wireless power supply device from the at least two second wireless power supply devices based on the fifth feedback signal may include: the communication equipment calculates redundancy coefficients of the second wireless power supply equipment, and sequences the at least two second wireless power supply equipment according to the sequence of the fifth feedback signals; and the communication equipment starts from the first second wireless power supply equipment after sequencing, selects the first second wireless power supply equipment meeting the preset condition as the target second wireless power supply equipment, wherein the preset condition comprises that the redundancy coefficient is greater than or equal to a preset threshold value and idle power supply antennas exist. For a specific procedure, reference may be made to the above description related to fig. 3, and this embodiment will not be discussed in detail here.

Illustratively, the fifth feedback signal may include, but is not limited to: a power threshold of the second wireless power supply device, a path loss power of the second wireless power supply device, a current load power of the second wireless power supply device, and so on. The process of the communication device calculating the redundancy factor of the second wireless power supply device may include: acquiring the operation power of the communication equipment and the power loss of the communication equipment; the redundancy factor of the second wireless power supply device is calculated based on a power threshold of the second wireless power supply device, a path loss power of the second wireless power supply device, a current load power of the second wireless power supply device, an operating power of the communication device, and a power loss of the communication device. For a specific procedure, reference may be made to the above description related to fig. 3, and this embodiment will not be discussed in detail here.

The target second wireless power supply device acts as a preferred wireless power supply device capable of charging a capacitor of the communication device, and the communication device transmits a sixth feedback signal to the target second wireless power supply device after selecting the target second wireless power supply device.

The communication device may transmit a sixth feedback signal to the second wireless power supply device if it receives only a fifth feedback signal transmitted by the second wireless power supply device.

The sixth feedback signal is for example used to instruct the target second wireless power supply device to start powering. The sixth feedback signal may be a 1bit signal.

In step 603, after receiving the second power supply signal transmitted by the target second wireless power supply device, the communication device charges the capacitor with the second power supply signal.

After receiving the sixth feedback signal transmitted by the communication device, the target second wireless power supply device knows that the communication device requests to start power supply, and can start charging a capacitor in the communication device at the moment, and the target second wireless power supply device transmits a second power supply signal to the communication device.

The communication device may utilize the second power supply signal to charge an internal capacitor after receiving the second power supply signal transmitted by the target second wireless power supply device.

The second power supply signal may be an electromagnetic wave, for example, but may also be any other form of power supply signal. After receiving the electromagnetic wave transmitted by the target second wireless power supply device, the communication device can convert the electromagnetic wave into electric energy and charge the capacitor.

In step 604, the communication device transmits a seventh feedback signal to the target second wireless power supply device when the electric quantity of the capacitor reaches a preset electric quantity.

And when the electric quantity of the capacitor reaches the preset electric quantity, the communication equipment can inform the target second wireless power supply equipment to disconnect power supply. Specifically, the communication device transmits a seventh feedback signal to the target second wireless power supply device, the seventh feedback signal being used to instruct the target second wireless power supply device to disconnect power. The seventh feedback signal may be a 1bit signal, for example. The specific value of the preset electric quantity can be set according to practical experience, and the embodiment is not limited to this. For example, the preset power may be 80%, 85%, 90%, etc.

And after receiving a seventh feedback signal transmitted by the communication equipment, the target second wireless power supply equipment knows that the power supply needs to be disconnected, and stops transmitting the second power supply signal to the communication equipment.

Step 605, after the target second wireless power supply device is powered off, the communication device switches from the to-be-operated mode to the sleep mode.

After the power supply of the target second wireless power supply equipment is disconnected, the communication equipment enters a sleep mode, so that the electric energy consumption is reduced, and occupation of a power supply interface of the wireless power supply equipment is avoided.

In the embodiment of the application, the purpose of real-time wireless power supply response of the passive low-power-consumption communication equipment is realized, and the guarantee is provided for information receiving and forwarding. Meanwhile, the inconvenience of deploying a fixed power supply, replacing a battery and the like for the communication equipment is avoided, and the reliability of the communication node network is enhanced.
