[0025] The management plane entity obtains the signal quality of each of the M detection terminals through feedback, and selects K detection terminals whose signal quality meets the preset conditions, or K detection terminals with relatively good signal quality. Since the channel quality of the detection terminals with better channel quality is different during this measurement, the K detection terminals selected each time are also different. In this way, the management plane entity constructs the route for this drone terminal inspection based on the locations of the K detection terminals. This not only ensures the effect of energy transmission to the drone terminal through relatively good signal quality at the locations of the K detection terminals, thereby ensuring endurance, but also ensures that the inspection route is different each time, thereby ensuring the inspection quality.

Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0037] To facilitate understanding of the embodiments of the present application, first Figure 1 The unmanned inspection of the hydropower station shown in FIG is used as an example to describe in detail the control system applicable to the embodiment of the present application. Figure 1 A schematic diagram of the architecture of an unmanned inspection of a hydropower station applicable to the method provided in an embodiment of the present application.

[0038] like Figure 1 As shown, the unmanned inspection system of the hydropower station may include: a management plane entity, a wireless access point and a terminal device.

[0039] The management plane entity may be a network element of the management plane, such as a management and orchestration (MANO) system.

[0040] The wireless access point may include a radio access network (RAN) device. The RAN device is also called a target RAN device, and the RAN device may be a device that provides access for the terminal. For example, the RAN device may include: the RAN device may also include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or a network node constituting a gNB, a transmission point (TRP or transmission point, TP) or a transmission measurement function (TMF), such as a baseband unit (BBU), a centralized unit (CU) or a distributed unit (DU), an RSU with base station function, or a wired access gateway, or a core network element of 5G. Alternatively, the RAN device may also include an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc. Alternatively, the RAN device may also include a next-generation mobile communication system, such as 6G access network equipment, such as a 6G base station, or in the next-generation mobile communication system, the network equipment may also have other naming methods, all of which are included in the protection scope of the embodiments of this application, and this application does not impose any limitations on this.

[0041] The terminal device may be a terminal having a communication function with a network (mobile communication network), or a chip or chip system that can be set in the terminal. The terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a vehicle-mounted terminal, an RSU with terminal function, etc. The terminal device of the present application may also be an onboard module, onboard module, onboard component, onboard chip, or onboard unit built into a vehicle as one or more components or units, and the vehicle may implement the method provided by the present application through the built-in onboard module, onboard module, onboard component, onboard chip, or onboard unit. Communication between terminals may be communication between terminals, which may also be called side communication.

[0042] In the embodiments of this application, the terminal devices include detection terminals and wireless terminals as an example. Both the detection terminal and the wireless terminal can belong to Internet of Things (IoT) devices, such as the ambient IoT (A-IoT). A-IoT is based on cellular network communication infrastructure and consists of readers (such as base stations) and passive / semi-passive / active A-IoT terminals (A-IoT terminals are terminals in the cellular network, which can be understood as extremely low-power, extremely low-complexity IoT terminals).

[0043] With the development of wireless networks and the evolution of service needs, a vast number of A-IoT terminals are now present in the network. These low-cost, small-sized A-IoT terminals cannot carry large-capacity batteries, resulting in short standby life. To address this issue, many manufacturers have proposed using ambient energy harvesting to provide a continuous source of energy for A-IoT terminals. Radio frequency energy is one candidate energy source, offering advantages such as controllable energy level and source, high penetration, and a long transmission distance.

[0044] Current RF energy harvesting solutions primarily focus on collecting radio electromagnetic waves from the natural environment. However, due to a lack of matching and coordinated optimization of energy sources, the energy harvesting efficiency is very low and cannot meet the daily needs of A-IoT terminals. Cellular mobile communication networks have a large number of base stations deployed. These base stations are equipped with multiple antennas, capable of transmitting arbitrarily designed electromagnetic waves and providing directional beams to enhance RF energy in certain directions, frequency bands, and time periods. This can significantly improve the low efficiency of energy transmission. Therefore, wireless energy transfer (WPT) through base stations is one of the important ways to address the battery life shortcomings of A-IoT terminals in the future. WPT is also known as wireless energy transmission, wireless charging, etc., and the specific terms are not limited.

[0045] It can be understood that the embodiments of the present application uniformly use beams for description, but beams can be replaced by other equivalent concepts and are not limited to the concepts mentioned above.

[0046] It can be understood that in this system, the wireless access point is a device in a private network. The private network can be a non-public network (NPN), which is a mobile communication network deployed for a hydropower station park and used to serve the hydropower station park. The management plane entity can manage the private network, such as configuring network elements / equipment, managing services, etc. The service can be the service of a third-party enterprise, such as the positioning and route planning involved in the embodiments of this application. It can be understood that, under normal circumstances, the MAMO system in the operator network is usually not responsible for managing the services of a third party, but since the private network in the embodiments of this application is for a third-party enterprise, such as a network deployed in a hydropower station park, its management services can be deeply bound to the services of the third-party enterprise, and these services can be configured in the MAMO system when configuring the network, thereby realizing the process of executing this application.

[0047] The following will be combined Figure 2 The interaction process between the devices in the above system is specifically described through a method embodiment. The unmanned inspection method based on a hydropower station provided in the embodiment of the present application can be applied to the above system, which is described in detail below.

[0048] Figure 2 The flowchart of the unmanned inspection method for a hydropower station provided in the embodiment of the present application is as follows:

[0049] S201: A management plane entity receives signal qualities of M detection terminals fed back by a wireless access point.

[0050] The management plane entity is used to manage wireless access points. There can be one or more wireless access points deployed at different locations within the hydropower station park, and their service cells can cover the hydropower station park.

[0051] M is an integer greater than 2.

[0052] M detection terminals are discretely deployed within the hydropower station campus. For example, each functional area within the hydropower station campus, such as the area where each unit is located, the control center, and the power transmission and transformation area, is equipped with a detection terminal. Each detection terminal is used to monitor the situation in its area. For example, the detection terminal can be a camera to collect surveillance video of the area and transmit it to the server in the control center via the user plane through the wireless access point to which it is connected. Alternatively, the detection terminal can be a sensor to collect the operating status of the device, such as current, voltage, load, temperature, etc. Each detection terminal is an environmental IoT device that can be wirelessly transmitted to it through the wireless access point to which it is connected.

[0053] The signal quality of each of the M detection terminals is the signal quality of the wireless access point transmitting wireless energy to the M detection terminals at the target time. Each wireless access point can transmit wireless energy to the detection terminals it connects to, and the timing of each wireless access point's wireless energy transmission can be aligned. For example, the timing of each wireless access point's wireless energy transmission is periodic, and these periods can be synchronized. For example, within each period, each wireless access point first performs a frequency domain scan, i.e., transmits the same beam for wireless energy transmission at different frequencies. Based on the signal quality of the beam returned by the detection terminals, the wireless access point determines the frequency at which the beam has the best signal quality, i.e., determines the optimal frequency. Each wireless access point then performs a spatial domain scan, i.e., sequentially transmits multiple beams at the optimal frequency. Based on the signal quality of each of the multiple beams returned by the detection terminals, the wireless access point determines the beam with the best signal quality, i.e., determines the optimal beam (i.e., the beam directed toward the detection terminal). The wireless access point can then transmit the optimal beam at the optimal frequency to transmit wireless energy to the detection terminals until the end of the period, thereby achieving relatively good energy transmission efficiency. The period of wireless energy transmission is also called the charging period within this cycle. The above process can be repeated in the next cycle. Alternatively, the next cycle can skip the spatial domain scan and perform only the frequency domain scan, using the best beam from the previous cycle. The above process can be repeated after several cycles, performing both frequency and spatial domain scans.

[0054] In the embodiments of the present application, the target time is the time at which the terminal reports the signal quality of each of the multiple beams within any given period. Alternatively, when only frequency domain scanning is performed within a given period, the target time may also be the time at which the terminal reports the beam quality at each frequency point within that period. The management plane entity may receive the signal quality of each of the M detected terminals from the wireless access point at the next time after the target time, such as the next timeslot / subframe / frame / radio frame. This feedback method may be pre-configured, meaning that the wireless access point will, by default, report the signal quality of each of the M detected terminals to the management plane entity at the next time the signal quality of each of the M detected terminals is received.

[0055] S202: The management plane entity determines K detection terminals whose signal quality meets a preset condition from the M detection terminals.

[0056] K is an integer greater than 1 and less than or equal to M. For example, the management plane entity can determine K detection terminals whose signal quality is greater than a preset signal quality threshold from the M detection terminals; or the management plane entity can also determine the top K detection terminals whose signal quality is the highest from the M detection terminals.

[0057] It can be understood that since the signal quality in the frequency domain is random, the signal quality of the detection terminal for frequency domain scanning feedback may be different in each cycle. Therefore, for the target time of different cycles, the K detection terminals whose signal quality meets the preset conditions may also be different, thereby ensuring the randomness of the subsequent inspection route.

[0058] S203: The management plane entity determines an inspection route for the drone terminal to inspect the hydropower station park during the inspection time period.

[0059] The inspection route includes the locations of K detection terminals. The management plane entity can pre-configure parameters such as the locations and identifiers of the M detection terminals.

[0060] The inspection time period includes the time period after the target time and when the signal quality is valid, that is, the charging time period within the above-mentioned cycle. Thus, the drone terminal can be configured to transmit energy through the wireless access point during the inspection along the inspection route within the inspection time period. It can be understood that the speed of the drone terminal is relatively fast and the inspection time is relatively short, such as 10-15 minutes, but the charging time (i.e., the charging time period) is usually relatively long, such as about 30 minutes. Therefore, the inspection time period can be included in the charging time period to enable the drone terminal to transmit energy through the wireless access point.

[0061] Among them, the drone terminal is specifically configured as follows: within the inspection time period, it patrols along the inspection route to the location of the i-th detection terminal among the K detection terminals, where i is an integer ranging from 1 to K. The drone terminal transmits wireless energy to the drone terminal through the wireless access point that transmits wireless energy to the i-th detection terminal based on the wireless energy transmission parameters of the i-th detection terminal.

[0062] For example, before the UAV terminal conducts an inspection along the inspection route within the inspection time period, the method further includes: the management plane entity obtains wireless power transmission parameters of each of the K detection terminals from the wireless access point, where the wireless power transmission parameters of the i-th detection terminal include resources that the i-th detection terminal needs to detect for wireless transmission, specifically, the i-th detection terminal's optimal frequency for wireless power transmission. The management plane entity sends the wireless power transmission parameters of each of the K detection terminals and the respective locations of the K detection terminals to the UAV terminal.

[0063] Alternatively, before the drone terminal conducts an inspection along the inspection route within the inspection time period, the method further includes: the management surface entity sends the respective identifiers of the K detection terminals, the respective information synchronization tokens of the K detection terminals, and the respective positions of the K detection terminals to the drone terminal, so that the drone terminal uses the respective information synchronization tokens of the K detection terminals to independently obtain the respective wireless energy transmission parameters of the K detection terminals from the K detection terminals. In other words, the drone terminal is configured to: inspect along the inspection route to the location of the i-th detection terminal among the K detection terminals within the inspection time period (specifically, the i-th detection terminal can be searched and a communication connection can be established with the i-th detection terminal, such as a PC5 connection), thereby obtaining the wireless energy transmission parameters of the i-th detection terminal from the i-th detection terminal based on the information synchronization token of the i-th detection terminal.

[0064] Specifically, the information synchronization token of the i-th detection terminal can include the signature of the i-th detection terminal and the joint signature of at least two detection terminals associated with the i-th detection terminal among the K detection terminals. The at least two detection terminals associated with the i-th detection terminal (such as 2 / 3 detection terminals) can be the detection terminals that are only 2 / 3 of the distance from the i-th detection terminal, or can be terminals determined by random grouping, such as randomly grouping M detection terminals into multiple groups, and the detection terminals in each group are all mutually related detection terminals. For example, group 1 includes terminal 1, terminal 2, terminal 3 and terminal 4, and the terminals associated with terminal 1 are terminal 2, terminal 3 and terminal 4, and the same applies to terminal 2, terminal 3 and terminal 4. The i-th detection terminal can be configured to: when verifying that the information synchronization token provided by the drone terminal contains the signature of the i-th detection terminal and the joint signature of at least two detection terminals, provide the drone terminal with the wireless energy transmission parameters of the i-th detection terminal, such as completed by establishing a PC5 connection.

[0065] More specifically, the joint signature of at least two detection terminals can include a partial signature of each of the at least two detection terminals. For example, the signature of each detection terminal is a hash string, and the partial signature of each detection terminal is a partial hash string within the hash string. In the joint signature of the at least two detection terminals, the last character of the partial hash string of the first detection terminal among the at least two detection terminals is swapped with the first character of the partial hash string of the second detection terminal among the at least two detection terminals, the last character of the partial hash string of the second detection terminal is swapped with the first character of the partial hash string of the third detection terminal among the at least two detection terminals, and so on.

[0066] For ease of understanding, in one example, continuing with Group 1 above, the joint signatures from Terminals 2 to 4 can be as follows: Terminal 2's partial signature includes SFAHGSF124, Terminal 3's partial signature includes DGFX214EE1, and Terminal 4's partial signature includes ASA1674GGF. The joint signature can be: SFAHGSF12D4GFX214EEA1SA1674GGF, which improves information security. Alternatively, the joint signature can be formed by swapping two or more characters, such as SFAHGSF1DG24FX214EASE1A1674GGF.

[0067] Since the i-th detection terminal pre-configures its own signature and partial signatures of at least two detection terminals, the i-th detection terminal performs the inverse process of the above rules to verify whether the signatures provided by the drone terminal are consistent with the local pre-configuration. If they are consistent, the verification passes and the wireless energy transmission parameters of the i-th detection terminal are provided. Otherwise, the verification fails and the wireless energy transmission parameters of the i-th detection terminal are not provided.

[0068] In an embodiment of the present application, the management plane entity replaces part of the preset inspection route of this inspection with a route determined according to the respective positions of the K detection terminals, and obtains the inspection route used by the drone terminal to inspect the hydropower station park during the inspection time period; wherein the preset inspection route is a route randomly selected by the management plane entity from multiple preset inspection routes. For example, the management plane entity can generate a route connecting the K detection terminals according to a map of the hydropower station park, that is, a route determined according to the respective positions of the K detection terminals. The management plane entity can determine whether there are at least two locations in the route connecting the K detection terminals that are located on the preset inspection route. If so, the part of the route in the preset inspection route that is connected to the at least two locations is replaced with the route connecting the K detection terminals to obtain the final inspection route, which can be specifically as follows. Figure 3 As shown in (a) in .

[0069] Or; the management surface entity adds the route determined according to the respective positions of the K detection terminals on the basis of the preset inspection route, and obtains the inspection route used by the drone terminal to inspect the hydropower station park during the inspection time period. For example, the management surface entity can also generate a route connecting the K detection terminals according to the map of the hydropower station park, that is, a route determined according to the respective positions of the K detection terminals. The management surface entity can determine whether there are at least two locations in the route connecting the K detection terminals located on the preset inspection route. If not, if there is only at least one location located on the preset inspection route, then the management surface entity adds the route connecting the K detection terminals on the basis of the preset inspection route to obtain the final inspection route; or, if no location is located on the preset inspection route, then the management surface entity generates a section of the route connecting the K detection terminals on the preset inspection route according to the map of the hydropower station park, which is connected to one end of the route connecting the K detection terminals, to obtain the final inspection route. Specifically, it can be as follows: Figure 3 In the embodiment of the present application, the algorithm for generating the route can be existing technology and is not specifically limited.

[0070] Finally, the management plane entity can send the final inspection route and inspection time period to the drone terminal through the wireless access point accessed by the drone terminal, so that the drone terminal can perform this inspection along the final inspection route at the beginning of the inspection time period.

[0071] In summary, the management plane entity obtains the signal quality of each of the M detection terminals through feedback, and selects K detection terminals whose signal quality meets the preset conditions, or K detection terminals with relatively good signal quality. Since the channel quality of the detection terminals with better channel quality is different during this measurement, the K detection terminals selected each time are also different. In this way, the management plane entity constructs the route for this drone terminal inspection based on the locations of the K detection terminals. Not only can it ensure the effect of energy transmission to the drone terminal through relatively good signal quality at the locations of the K detection terminals, thereby ensuring endurance, but it can also ensure that the inspection route is different each time, thereby ensuring the inspection quality.
