[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] Reference Figure 1 The diagram illustrates a device interaction according to an embodiment of this application. Figure 1 As shown, the devices involved in the embodiments of this application may include at least a first device, a communication device, a wireless power supply device, and a second device.

[0051] The first device acts as the information sender. The first device can transmit probe signals (such as activation signals) to the communication device, receive feedback signals transmitted by the communication device, transmit information to the communication device, and so on. For example, the first device can be various terminals with information processing capabilities, such as smartphones, tablets, etc.

[0052] The communication device acts as a relay, transmitting information. It can transmit feedback signals to a first device, receive information transmitted by the first device, transmit information to a second device, transmit detection signals to a wireless power supply device, receive feedback signals transmitted by the wireless power supply device, receive electromagnetic waves emitted by the wireless power supply device, and so on. For example, the communication device can be various relay devices with information transmission capabilities, such as a base station. The communication device in this embodiment is a passive communication device.

[0053] Wireless power supply devices are used to power communication devices. These devices can receive detection signals emitted by the communication device, transmit feedback signals to the communication device, emit electromagnetic waves, and so on. For example, wireless power supply devices can be various devices with wireless power supply capabilities.

[0054] The second device acts as an information receiver. The second device can receive information transmitted by communication devices, and so on. For example, the second device can be various terminals with information processing capabilities, such as smartphones, tablets, etc.

[0055] Reference Figure 2 The diagram illustrates a flowchart of the steps of a wireless power supply method for a communication device according to an embodiment of this application.

[0056] like Figure 2 As shown, the wireless power supply method for communication devices may include the following steps:

[0057] Step 201: After receiving the activation signal transmitted by the first device, the communication device transmits the first detection signal.

[0058] When the first device needs to send information but cannot directly transmit the information to the second device, it will send an activation signal to the communication device.

[0059] For example, the activation signal is used to notify the communication device that the first device needs to send information, thereby instructing the communication device to activate. The activation signal can be a 1-bit signal.

[0060] After receiving the activation signal transmitted by the first device, the communication device knows that the first device needs to send information, that is, it needs to forward information. At this time, it needs to request power from the surrounding wireless power supply devices. Therefore, the communication device will transmit the first detection signal to the surrounding wireless power supply devices.

[0061] For example, the first probe signal is used to notify the wireless power supply device that the communication device needs to be powered. The communication device may broadcast the first probe signal in multiple bits to surrounding wireless power supply devices.

[0062] Step 202: After receiving the first feedback signal 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 signal, and transmits a second feedback signal to the target first wireless power supply device.

[0063] For ease of distinction, in this embodiment of the application, the wireless power supply device that receives the first detection signal transmitted by the communication device and returns a first feedback signal to the communication device is referred to as the first wireless power supply device. For any given first wireless power supply device, after receiving the first detection signal transmitted by the communication device, the first wireless power supply device deciphers that the communication device needs to be powered, and at this time, the first wireless power supply device will transmit a first feedback signal to the communication device.

[0064] For example, the first feedback signal is used to notify the communication device that the first wireless power supply device is capable of supplying power. The first feedback signal can be a 1-bit signal.

[0065] If a communication device receives a first feedback signal transmitted by at least two first wireless power supply devices, it can select a target first wireless power supply device from the at least two first wireless power supply devices based on the first feedback signal transmitted by the at least two first wireless power supply devices.

[0066] Reference Figure 3 The diagram illustrates a process flowchart for selecting a target first wireless power supply device according to an embodiment of this application.

[0067] like Figure 3 As shown, the process for selecting the target first wireless power supply device may include the following steps:

[0068] Step 301: The communication device calculates the redundancy coefficient of the first wireless power supply device and sorts the at least two first wireless power supply devices according to the order in which the first feedback signals are received.

[0069] For each first wireless power supply device, the communication device calculates the redundancy coefficient of that first wireless power supply device.

[0070] For example, the first feedback signal may include, but is not limited to: the power threshold of the first wireless power supply device, the path loss power of the first wireless power supply device, the current load power of the first wireless power supply device, etc.

[0071] For example, the process of calculating the redundancy coefficient of the first wireless power supply device by the communication device may include: obtaining the operating power (actual operating power) and power loss of the communication device; and calculating the redundancy coefficient of the first wireless power supply device based on the power threshold, path loss power, current load power, operating power, and power loss of the communication device.

[0072] For example, the redundancy factor of the first wireless power supply device can be calculated based on the following formula:

[0073] P th -(P r +P c +P s )=ηP w

[0074] In this formula, η represents the redundancy coefficient of the first wireless power supply device, and P th P represents the power threshold of the first wireless power supply device. r P represents the path loss power of the first wireless power supply device. c P represents the current load power of the first wireless power supply device. w P represents the operating power of communication equipment. s This indicates the power loss of communication equipment.

[0075] For the at least two first wireless power supply devices, the communication device sorts the at least two first wireless power supply devices according to the order in which the first feedback signals are received. Specifically, the first wireless power supply device corresponding to the earliest received first feedback signal is listed first, and the first wireless power supply device corresponding to the latest received first feedback signal is listed last; that is, the first wireless power supply device corresponding to the first received first feedback signal is listed first, and the first wireless power supply device corresponding to the later received first feedback signal is listed last.

[0076] Step 302: Starting from the first wireless power supply device after sorting, the communication device selects the first wireless power supply device that meets the preset conditions as the target wireless power supply device. The preset conditions include a redundancy coefficient greater than or equal to a preset threshold and the existence of an idle power supply antenna.

[0077] Starting with the first wireless power supply device after sorting, the communication device determines whether the redundancy coefficient of the current wireless power supply device is greater than or equal to a preset threshold, and whether the current wireless power supply device has an idle power supply antenna; if the redundancy coefficient of the current wireless power supply device is greater than or equal to the preset threshold, and the current wireless power supply device has an idle power supply antenna, the current wireless power supply device is determined as the target wireless power supply device.

[0078] For example, the communication device sorts the first wireless power supply devices into three categories—first wireless power supply device A, first wireless power supply device B, and first wireless power supply device C—based on the order in which the first feedback signals transmitted by the first wireless power supply device are received. If the redundancy coefficient of first wireless power supply device A is greater than or equal to a preset threshold, and the first wireless power supply device has an idle power supply antenna, then first wireless power supply device A is selected as the target first wireless power supply device. If first wireless power supply device A does not meet the above conditions, then the judgment is continued on first wireless power supply device B, and so on, until the target first wireless power supply device is selected.

[0079] The specific value of the above-mentioned preset threshold can be set based on actual experience, and this embodiment does not impose any restrictions on it.

[0080] For example, if the preset threshold is set to 1, the preset condition can be expressed as follows: η≥1, r≥1, where η represents the redundancy coefficient and r represents the number of idle power supply antennas. The set of first wireless power supply devices with a redundancy coefficient greater than or equal to 1 can be represented as follows:

[0081] The target first wireless power supply device is the preferred wireless power supply device capable of supplying power to the communication device. After selecting the target first wireless power supply device, the communication device transmits a second feedback signal to the target first wireless power supply device.

[0082] If a communication device receives only a first feedback signal transmitted by a first wireless power supply device, it can transmit a second feedback signal to that first wireless power supply device.

[0083] For example, the second feedback signal is used to instruct the target first wireless power supply device to start powering on. The second feedback signal can be a 1-bit signal.

[0084] Step 203: 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.

[0085] After receiving the second feedback signal transmitted by the communication device, the first wireless power supply device knows that the communication device has requested to start power supply. At this time, it can start to supply power to the communication device, and the first wireless power supply device will transmit the first power supply signal to the communication device.

[0086] 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. The power supply here is used to ensure the normal operation of the communication device, such as receiving information, forwarding information, etc.

[0087] For example, the first power supply signal can be an electromagnetic wave, or 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 electrical energy and provide power to itself.

[0088] In this embodiment, on the one hand, by using signal feedback between the passive communication device and the wireless power supply device, the wireless power supply device can provide real-time power to the passive communication device when it needs power, thus ensuring the normal operation of the communication device and avoiding the inconvenience of deploying a fixed power supply and replacing batteries for the communication device, thereby enhancing the reliability of the communication device network. On the other hand, by selecting a target wireless power supply device from multiple wireless power supply devices, the power supply strategy can be optimized, making the power supply process of the wireless power supply device more stable and efficient.

[0089] Reference Figure 4 The diagram illustrates a flowchart of another method for wireless power supply of a communication device according to an embodiment of this application.

[0090] like Figure 4 As shown, the wireless power supply method for communication devices may include the following steps:

[0091] Step 401: After receiving the activation signal transmitted by the first device, the communication device switches from sleep mode to standby mode and transmits the first detection signal.

[0092] When communication devices are not receiving or forwarding information, they will enter sleep mode. Sleep mode reduces power consumption and eliminates the need for wireless power supply, thus avoiding the use of the wireless power supply's power interface and promoting green and low-carbon development.

[0093] After receiving the activation signal transmitted by the first device, the communication device can switch from sleep mode to standby mode to prepare for receiving and forwarding information. In standby mode, the communication device will prepare to receive and forward information and execute the following step 402.

[0094] Step 402: After receiving the first feedback signal 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 signal, and transmits a second feedback signal to the target first wireless power supply device.

[0095] 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 switches from the standby mode to the operating mode.

[0096] After the communication device receives power from the first power supply signal, it will switch from the standby mode to the operating mode. In the operating mode, the communication device will perform normal information reception and forwarding.

[0097] 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.

[0098] After the communication device uses the first power supply signal to power the communication device and switches from the standby mode to the operating mode, it will send a third feedback signal to the first device.

[0099] After receiving the third feedback signal from the communication device, the first device can begin sending information to the communication device. Upon receiving the information from the first device, the communication device can forward this information to the second device.

[0100] Step 405: If the communication device does not process information within a preset time period, it transmits a fourth feedback signal to the target first wireless power supply device. The fourth feedback signal is used to instruct the target first wireless power supply device to disconnect the power supply.

[0101] If the communication device fails to process information within a preset time period, it can notify the target first wireless power supply device to disconnect the power supply. Specifically, the communication device transmits a fourth feedback signal to the target first wireless power supply device, which instructs the target first wireless power supply device to disconnect the power supply. For example, the fourth feedback signal can be a 1-bit signal. The specific value of the preset time period can be set based on practical experience, and this embodiment does not impose any restrictions on it.

[0102] Upon receiving the fourth feedback signal transmitted by the communication device, the target wireless power supply device recognizes the need to disconnect power and ceases transmitting the first power supply signal to the communication device. This method allows for timely disconnection of power when the communication device is relatively idle, thereby saving energy.

[0103] Step 406: After the target first wireless power supply device disconnects the power supply, the communication device switches from the operating mode to the sleep mode.

[0104] After the target's first wireless power supply device is disconnected, the communication device enters sleep mode, thereby reducing power consumption and avoiding the occupation of the power supply interface of the wireless power supply device.

[0105] In this embodiment of the application, the communication device is configured with a sleep mode, a standby mode, and a running mode, and the modes can be switched between each other.

[0106] Reference Figure 5 The diagram illustrates a communication device operation mode according to an embodiment of this application. Figure 5 As shown, the communication device can switch from sleep mode to standby mode, from standby mode to running mode, and from running mode to sleep mode.

[0107] In one alternative embodiment, a capacitor can be installed inside the communication device. Since the communication device consumes less power in sleep mode and standby mode, the communication device can be powered by the internal capacitor in these modes. For example, in the above-described workflow, the processes of the communication device transmitting the first detection signal, transmitting the second feedback signal, and selecting the target first wireless power supply device can all be powered by the internal capacitor.

[0108] In one alternative implementation, when the communication device is in operating mode, the target first wireless power supply device will charge the capacitor in preparation for the next power supply use. Therefore, after receiving the first power supply signal transmitted by the target first wireless power supply device, the communication device can also use the first power supply signal to charge the capacitor.

[0109] In one alternative implementation, since the communication device is powered by a capacitor when it is in sleep mode, the capacitor will consume power. In order to avoid the power supply being affected by the low power of the capacitor, the capacitor can be charged in time according to the power status of the capacitor during sleep mode.

[0110] Reference Figure 6 The diagram illustrates a process flow chart of a communication device in sleep mode according to an embodiment of this application.

[0111] like Figure 6 As shown, the process for a communication device to be in sleep mode may include the following steps:

[0112] Step 601: When the communication device is in the sleep mode and the power consumption of the capacitor reaches a preset ratio, it switches from the sleep mode to the standby mode and transmits a second detection signal.

[0113] The specific value of the preset ratio can be set based on practical experience, and this embodiment does not impose any restrictions on it. For example, the preset ratio can be set to 50%, 60%, etc.

[0114] When the communication device is in the sleep mode and the power consumption of the capacitor reaches a preset ratio, it switches from the sleep mode to the standby mode and transmits a second detection signal to the surrounding wireless power supply devices.

[0115] For example, the second probe signal is used to notify the wireless power supply device that the capacitor inside the communication device needs to be charged. The communication device may broadcast the second probe signal in multiple bits to surrounding wireless power supply devices.

[0116] Step 602: After receiving the fifth feedback signal transmitted by 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 signal, and transmits a sixth feedback signal to the target second wireless power supply device.

[0117] For ease of distinction, in this embodiment, the wireless power supply device that receives the second detection signal transmitted by the communication device and returns a fifth feedback signal to the communication device is referred to as the second wireless power supply device. For any given second wireless power supply device, upon receiving the second detection signal transmitted by the communication device, it learns that the capacitor inside the communication device needs to be charged. At this time, the second wireless power supply device will transmit a fifth feedback signal to the communication device.

[0118] For example, the fifth feedback signal is used to notify the communication device that the second wireless power supply device is capable of supplying power. The fifth feedback signal can be a 1-bit signal.

[0119] If the communication device receives a fifth feedback signal transmitted by at least two second wireless power supply devices, it can select a target second wireless power supply device from the at least two second wireless power supply devices based on the fifth feedback signal transmitted by the at least two second wireless power supply devices.

[0120] For example, the process of selecting a 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 device calculating the redundancy coefficient of the second wireless power supply device, and sorting the at least two second wireless power supply devices according to the order in which the fifth feedback signal is received; starting from the first sorted second wireless power supply device, the communication device selects the first second wireless power supply device that meets a preset condition as the target second wireless power supply device, the preset condition including a redundancy coefficient greater than or equal to a preset threshold and the existence of an idle power supply antenna. For the specific process, refer to the above description for... Figure 3 The relevant explanations will not be discussed in detail in this embodiment.

[0121] For example, the fifth feedback signal may include, but is not limited to: the power threshold of the second wireless power supply device, the path loss power of the second wireless power supply device, the current load power of the second wireless power supply device, etc. The process of the communication device calculating the redundancy coefficient of the second wireless power supply device may include: obtaining the operating power and power loss of the communication device; and calculating the redundancy coefficient of the second wireless power supply device based on its power threshold, path loss power, current load power, operating power, and power loss. For a specific process, refer to the above description... Figure 3 The relevant explanations will not be discussed in detail in this embodiment.

[0122] The target second wireless power supply device is a preferred wireless power supply device capable of charging the capacitor of the communication device. After selecting the target second wireless power supply device, the communication device transmits a sixth feedback signal to the target second wireless power supply device.

[0123] If a communication device receives only a fifth feedback signal transmitted by a second wireless power supply device, it can transmit a sixth feedback signal to that second wireless power supply device.

[0124] For example, the sixth feedback signal is used to instruct the target second wireless power supply device to start powering on. The sixth feedback signal can be a 1-bit signal.

[0125] Step 603: After receiving the second power supply signal transmitted by the target second wireless power supply device, the communication device uses the second power supply signal to charge the capacitor.

[0126] After receiving the sixth feedback signal transmitted by the communication device, the second wireless power supply device knows that the communication device has requested to start power supply. At this time, it can start charging the capacitor inside the communication device, and the second wireless power supply device will transmit a second power supply signal to the communication device.

[0127] After receiving the second power supply signal transmitted by the target second wireless power supply device, the communication device can use the second power supply signal to charge the internal capacitor.

[0128] For example, the second power supply signal can be an electromagnetic wave, or any other form of power supply signal. After receiving the electromagnetic wave emitted by the target second wireless power supply device, the communication device can convert the electromagnetic wave into electrical energy and charge the capacitor.

[0129] Step 604: When the capacitor's charge reaches a preset level, the communication device transmits a seventh feedback signal to the target second wireless power supply device.

[0130] When the capacitor's charge reaches a preset level, the communication device can notify the target second wireless power supply device to disconnect the power supply. Specifically, the communication device transmits a seventh feedback signal to the target second wireless power supply device, which instructs the target second wireless power supply device to disconnect the power supply. For example, the seventh feedback signal can be a 1-bit signal. The specific value of the preset charge level can be set based on practical experience, and this embodiment does not impose any limitations on this. For example, the preset charge level can be 80%, 85%, 90%, etc.

[0131] Upon receiving the seventh feedback signal transmitted by the communication device, the target second wireless power supply device learns that it needs to disconnect the power supply and then stops transmitting the second power supply signal to the communication device.

[0132] Step 605: After the target second wireless power supply device disconnects the power supply, the communication device switches from the standby mode to the sleep mode.

[0133] After the target second wireless power supply device is disconnected, the communication device enters sleep mode, thereby reducing power consumption and avoiding the occupation of the power supply interface of the wireless power supply device.

[0134] In this embodiment, the goal of real-time wireless power supply response for passive low-power communication devices is achieved, ensuring information reception and forwarding. Simultaneously, it avoids the inconvenience of deploying fixed power supplies and replacing batteries for communication devices, enhancing the reliability of the communication node network.
