It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] Figure 1 This is a flowchart of a method for determining the fiber optic power supply strategy of a base station according to an embodiment of the present invention, as follows: Figure 1 As shown, the method includes the following steps:

[0026] S102, acquire energy supply data from the power supply station and energy consumption data from the target base station.

[0027] This involves power supply stations, which are the source sites for providing electricity and are responsible for transmitting the energy to the target base station via optical fiber. Specifically, this power supply station can be a central station.

[0028] This includes energy supply data, which consists of various data related to energy output generated by the energy supply station during the energy supply process, such as the energy optical power allocated by the energy supply station to the target base station, the length of the optical fiber laid, and the bending sensitivity of the optical fiber.

[0029] This involves the target base station, which is a base station that needs to receive and use electrical energy transmitted from the power supply station through optical fiber to operate. It is the receiving end of the optical fiber power supply system and includes multiple electrical devices, such as communication equipment and monitoring equipment.

[0030] This includes energy consumption data, which refers to various data related to energy consumption generated by the target base station during operation, including but not limited to the base station's total energy consumption requirements, the rated power consumption of each electrical device, the actual operating power consumption, energy consumption fluctuations under different operating conditions, and battery energy storage status (such as rated capacity and current power percentage).

[0031] By acquiring energy supply data from power supply stations and energy consumption data from target base stations, we can gain a comprehensive understanding of the energy supply characteristics of power supply stations and the energy consumption characteristics of target base stations, providing a basis for subsequent analysis.

[0032] S104, determine multiple optical fiber links corresponding to the target base station, wherein the multiple optical fiber links are connected between the power supply station and the target base station, and the multiple optical fiber links correspond to different power supply risk indices.

[0033] This involves multiple fiber optic links, which are the fiber optic transmission paths between the power supply station and the target base station. These multiple fiber optic links differ in terms of power supply route length, fiber condition, and geological environment, thus resulting in different power supply characteristics.

[0034] This includes a power supply risk index, which is used to quantify the degree of instability risk during the power supply process of each optical fiber link. The value of the power supply risk index directly reflects the reliability of the power supply of the optical fiber link. The power supply risk index can be determined based on the power supply route length, optical fiber bending sensitivity, and geological risk index of multiple optical fiber links respectively.

[0035] By identifying multiple fiber optic links between the power supply station and the target base station that differ in power supply route length, fiber optic condition, and geological environment, and quantifying their respective power supply risk indices, the reliability of each link's power supply can be accurately assessed. This allows for the selection of low-risk links for power supply, ensuring that the target base station receives stable and reliable power transmission.

[0036] S106. Based on the power supply risk index corresponding to each of the multiple optical fiber links, determine multiple target links from the multiple optical fiber links. Among them, the multiple target links are optical fiber links whose power supply risk index is less than the power supply risk threshold.

[0037] This involves multiple target links, which are optical fiber transmission paths selected from multiple optical fiber links between the power supply station and the target base station, and whose power supply risk index is lower than a preset power supply risk threshold.

[0038] By selecting multiple target links with a power supply risk index below a preset threshold from multiple fiber optic links based on the power supply risk index, high-risk paths with unstable power supply can be eliminated, ensuring that the links participating in the determination of the power supply strategy have basic reliability. This provides a high-quality link foundation for matching corresponding relay stations and accurately calculating auxiliary power supply power, thereby ensuring that the final determined fiber optic power supply strategy can stably adapt to the power supply needs of the target base station.

[0039] S108, determine the relay stations corresponding to multiple target links respectively, wherein the corresponding relay stations are used to assist the power supply station in providing fiber optic power to the target base station.

[0040] This involves relay stations, which are auxiliary power supply stations set up between the power supply station and the target base station in the corresponding target link. They are used to enhance or supplement the power in the fiber optic transmission and ensure that the target base station receives a stable and reliable power supply.

[0041] This involves fiber optic power supply, which is a power supply method that uses optical fiber as a transmission medium to transmit electrical energy from a power supply station to a target base station over a long distance.

[0042] By identifying corresponding relay stations for the selected target links, and using these relay stations as auxiliary power supply nodes between the power supply station and the target base station, the power loss during optical fiber transmission can be enhanced or supplemented, and the energy attenuation problem of the target link in long-distance transmission can be compensated. This provides a reliable analytical basis for determining the subsequent optical fiber power supply strategy.

[0043] S110, determine the auxiliary power supply corresponding to each of the multiple relay stations, wherein the corresponding auxiliary power supply is the power supply of the relay station to the target base station for fiber optic power supply, and the multiple relay stations correspond one-to-one with the multiple target links.

[0044] This includes auxiliary power supply, which is the additional power provided by the relay station to supplement the electrical energy lost during the fiber optic power supply process of the target base station.

[0045] By determining the auxiliary power supply power corresponding to multiple relay stations, the energy replenishment status of each target link can be accurately quantified, providing data support for subsequent determination of fiber optic power supply strategies.

[0046] S112, based on power supply data, power consumption data, and the auxiliary power supply power corresponding to multiple relay stations, determines the fiber optic power supply strategy corresponding to the target base station.

[0047] This involves a fiber optic power supply strategy, which is a strategy for allocating power to the target base station based on a comprehensive assessment of power supply data (such as the output power of the power supply station, transmission loss, etc.), energy consumption data (such as the actual power consumption of the target base station), and the auxiliary power supply power of each relay station. This strategy includes the final set of relay stations, the priority of relay station use, the allocation of auxiliary power supply power, and the energy allocation of each electrical device.

[0048] The energy supply data clarifies the energy output capacity and basic transmission conditions of the energy supply station, while the energy consumption data accurately reflects the total energy consumption demand of the target base station, the power consumption of each electrical device, and the energy storage status. The auxiliary power supply of each relay station matches the energy loss replenishment needs of different target links. These three data provide comprehensive and accurate quantitative basis from three core dimensions: energy supply head, receiving end demand, and link replenishment. This enables a comprehensive understanding of the input, output, and relay operation characteristics of the energy supply system, and thus accurately determines the fiber optic power supply strategy adapted to the base station.

[0049] Through the above steps S102-S112, the power supply data of the power supply station and the power consumption data of the target base station are obtained; multiple optical fiber links corresponding to the target base station are determined, wherein the multiple optical fiber links are connected between the power supply station and the target base station, and the multiple optical fiber links correspond to different power supply risk indices; based on the power supply risk indices corresponding to the multiple optical fiber links, multiple target links are determined from the multiple optical fiber links, wherein the multiple target links are optical fiber links whose power supply risk index is less than the power supply risk threshold; relay stations corresponding to the multiple target links are determined, wherein the corresponding relay stations are used to assist the power supply station in providing optical fiber power to the target base station; auxiliary power supply power corresponding to the multiple relay stations is determined, wherein the corresponding auxiliary power supply power is the power supply power of the relay station to assist in providing optical fiber power to the target base station, and the multiple relay stations correspond one-to-one with the multiple target links; based on the power supply data, power consumption data, and the auxiliary power supply power corresponding to the multiple relay stations, the optical fiber power supply strategy corresponding to the target base station is determined. By acquiring power supply data from the power supply station, power consumption data from the target base station, and multiple fiber optic links between the power supply station and the target base station corresponding to different power supply risk indices, the output capacity of the power supply head, the energy demand of the base station, and the risk differences of each link can be clearly identified. Based on this, multiple target links with risks below a threshold are selected according to the power supply risk index, avoiding the impact of high-risk links on power supply stability. Next, relay stations corresponding to these target links are identified, and their auxiliary role can compensate for link transmission losses, strengthening the continuity of power supply. Furthermore, the auxiliary power supply power corresponding to each relay station is determined, allowing for precise matching of the power supply supplementation intensity for each link, ensuring that the power output matches the link demand. Finally, by combining the power supply data, power consumption data, and the auxiliary power supply power of each relay station, an accurate fiber optic power supply strategy adapted to the base station can be determined, thereby improving the power supply reliability of the target base station. This solves the technical problem in related technologies where inaccurate fiber optic power supply strategies lead to unreliable power supply to the base station.

[0050] As an optional embodiment, determining the auxiliary power supply corresponding to each of the multiple relay stations includes: for any one of the multiple relay stations, determining the auxiliary power supply corresponding to that relay station using the following method: determining the power loss index and multiple auxiliary power supply methods corresponding to that relay station, wherein the power loss index represents the degree of power loss when any relay station supplies fiber power to the target base station; determining the initial power supply corresponding to that relay station based on the power loss index; determining the power enhancement index corresponding to each of the multiple auxiliary power supply methods; and determining the auxiliary power supply corresponding to that relay station based on the initial power supply and the power enhancement index corresponding to each of the multiple auxiliary power supply methods.

[0051] This involves any one relay station, which is any one of multiple relay stations used to determine the auxiliary power supply.

[0052] This includes the power loss index, which is a quantitative indicator used to quantify the degree of energy loss during transmission when any relay station supplies power to the target base station via optical fiber. The magnitude of the index directly corresponds to the severity of the power loss.

[0053] This involves multiple auxiliary power supply methods, which are different power supply modes or technical means that any relay station can adopt to improve power supply efficiency. These include physical co-location power supply, functional resource sharing power supply, and sensor coupling collaborative power supply, each with a different power enhancement effect. For example, these multiple auxiliary power supply methods include deep physical overlap, functional resource overlap, and sensor coupling overlap.

[0054] This involves the initial power supply, which is the power supply value initially determined to compensate for the basic transmission loss when no additional auxiliary power supply method is used, based on the power supply loss index corresponding to any relay station.

[0055] This includes a power enhancement index, which is used to quantify the effect of the corresponding auxiliary power supply method on the initial power supply. It can reflect the proportion or magnitude by which the corresponding auxiliary power supply method can increase the power supply.

[0056] By defining the power loss index corresponding to any relay station to quantify the degree of energy transmission loss, and then determining the initial power supply to compensate for the basic transmission loss based on the loss index, the power enhancement index corresponding to different auxiliary power supply methods is defined to understand the power enhancement effect of each method. Finally, the auxiliary power supply power of any relay station is accurately calculated by combining the initial power supply power and the power enhancement index. This approach considers both the inherent link loss and the gain effect of auxiliary power supply, ensuring that the auxiliary power supply power of each relay station is accurately matched with the loss characteristics and power supply requirements of the corresponding target link. This provides reliable power parameter support for the subsequent formulation of accurate fiber optic power supply strategies, thereby solving the technical problem of unreliable base station power supply caused by inaccurate power supply strategies in related technologies.

[0057] As an optional embodiment, determining the initial power supply corresponding to any relay station based on the power loss index includes: determining the power transmission index corresponding to any relay station based on the power loss index, wherein the power transmission index is used to represent the power transmission level of any relay station; determining the allocated power of the power supply station to the target base station; and determining the initial power supply corresponding to any relay station based on the power transmission index and the allocated power.

[0058] This includes the power transmission index, which is used to quantify the extent to which the power output of any relay station can be effectively transmitted to the target base station. It can be represented by the effective transmission ratio of the power supplied from the relay station to the target base station.

[0059] This involves the allocation of power, which is the total power supply quota that the power supply station plans and allocates in advance for the target base station based on its overall energy demand. It serves as the basic reference benchmark for calculating the initial power supply of the relay station.

[0060] By determining the power transmission index, the transmission efficiency of power from the relay station to the target base station can be clearly defined. Using the power allocation planned for the target base station as the basic reference benchmark, the initial power supply power of any relay station can be determined by combining the two. This ensures that the initial power supply power is both adapted to the link transmission characteristics and compensates for inherent losses, and also conforms to the overall power supply plan of the power supply station. This ensures that the calculation of the initial power supply power is accurate and reasonable, providing a data foundation for the subsequent accurate determination of the fiber optic power supply strategy.

[0061] As an optional embodiment, based on power supply data, power consumption data, and the auxiliary power supply power corresponding to multiple relay stations, a fiber optic power supply strategy corresponding to the target base station is determined, including: determining the total power corresponding to the target base station based on the auxiliary power supply power corresponding to multiple relay stations; determining the power consumption parameters and equipment weight index corresponding to multiple electrical devices, wherein the equipment weight index is used to represent the importance of the corresponding electrical device, and the target base station includes multiple electrical devices; determining multiple first operating durations corresponding to the target base station based on the total power supply, and the power consumption parameters and equipment weight index corresponding to multiple electrical devices, wherein the multiple first operating durations correspond one-to-one with multiple relay stations; and determining the fiber optic power supply strategy corresponding to the target base station based on the power supply data, power consumption data, and multiple first operating durations.

[0062] This includes total electrical energy, which is the total available electrical energy value that can be used by the target base station, determined by combining the auxiliary power supply power of each relay station, and covering the power supply contribution of all relay stations.

[0063] This includes power consumption parameters, which are used to quantify the energy consumption characteristics of the corresponding electrical equipment during operation. These parameters can be represented by the power consumption of the corresponding electrical equipment in the lowest acceptable operating mode.

[0064] This includes the equipment weight index, which is used to quantify the importance of the corresponding power equipment in the target base station. The higher the value, the higher the priority of the corresponding power equipment in the target base station. It can be used to represent the proportion of the corresponding power equipment in the critical guarantee energy allocation in critical guarantee scheduling.

[0065] This involves electrical equipment, which is the main carrier of energy consumption in the target base station, including various devices inside the target base station that perform functions such as communication signal transmission and reception, data processing, and equipment testing.

[0066] This involves multiple first runtimes, which are the duration for which the target base station maintains the continuous operation of the power-consuming equipment. This can be expressed as the duration for which the target base station maintains the power-consuming equipment at the lowest power consumption.

[0067] Because the total power consumption can quantify the upper limit of the base station's available energy, and power can be allocated by combining the power consumption parameters of the electrical equipment and the equipment weight index, it can ensure that key equipment receives priority power supply. Furthermore, by determining multiple first operating durations based on the total power consumption and equipment demand, it is possible to accurately predict the continuous operating capability of the base station under different relay station configurations. Thus, by integrating power supply data, power consumption data, and multiple first operating durations, it is possible to fully connect power supply, equipment demand, and operational support capabilities, thereby enabling the accurate determination of fiber optic power supply strategies, avoiding equipment downtime or resource waste caused by unreasonable energy allocation, and ensuring the reliability of the target base station's operation.

[0068] As an optional embodiment, based on power supply data, power consumption data, and multiple first operating durations, a fiber optic power supply strategy corresponding to the target base station is determined, including: determining an auxiliary gain index corresponding to multiple relay stations based on multiple first operating durations, wherein the corresponding auxiliary gain index is used to represent the degree to which the corresponding relay station assists in reducing the operational risk of the target base station; and determining a fiber optic power supply strategy corresponding to the target base station based on power supply data, power consumption data, and the auxiliary gain index corresponding to multiple relay stations.

[0069] This includes the auxiliary gain index, which is an index determined based on multiple first runtimes and used to quantify the degree to which relay stations assist in reducing the operational risks of target base stations. Its core is to measure the comprehensive ratio of the benefits brought to the base station by the relay station through auxiliary power supply, such as improved power supply stability and extended emergency runtime, to the deployment and risk reduction costs.

[0070] This includes operational risks, which are risks that may arise during the operation of the target base station, such as insufficient power supply, power interruption, or imbalance in energy distribution, which may cause key equipment of the base station to malfunction or reduce overall operational stability.

[0071] Since the auxiliary gain index of each relay station is determined based on multiple first run times, the improvement benefits of different relay stations on the power supply stability of the base station can be quantified, and the relay stations that contribute more to reducing operational risks can be identified first. By combining power supply data and energy consumption data to optimize the weight allocation of the auxiliary gain index, it can be ensured that the fiber optic power supply strategy focuses on the resource scheduling of key relay stations, avoids the shutdown of key equipment of the base station due to power supply fluctuations, and ultimately minimizes the operational risks of the base station and maximizes the power supply efficiency.

[0072] As an optional embodiment, based on power supply data, power consumption data, and auxiliary gain indices corresponding to multiple relay stations, a fiber optic power supply strategy corresponding to the target base station is determined, including: determining usage indices corresponding to multiple relay stations based on the auxiliary gain indices corresponding to multiple relay stations, wherein the corresponding usage index indicates the degree to which the corresponding relay station is used for auxiliary fiber optic power supply; and determining the fiber optic power supply strategy corresponding to the target base station based on power supply data, power consumption data, and usage indices corresponding to multiple relay stations.

[0073] This includes a usage index, which is determined based on the relay station auxiliary gain index. This index is used to quantify the intensity of each relay station's actual participation in the target base station's fiber optic power supply task, reflecting the degree to which the corresponding relay station is used for auxiliary fiber optic power supply.

[0074] By determining the usage index based on the relay station auxiliary gain index to quantify the intensity of each relay station's participation in the power supply task, the degree of power supply participation of different relay stations is clearly defined. By combining these usage index information with power supply data and energy consumption data, the precise allocation of power supply resources among relay stations can be achieved. This ensures that the degree of power supply participation is highly matched with link requirements and base station energy consumption requirements, avoiding power oversupply or undersupply caused by unreasonable use of relay stations. As a result, the fiber optic power supply strategy is more in line with the actual power supply scenario, solving the technical problem of unreliable base station power supply caused by inaccurate power supply strategies in related technologies.

[0075] As an optional embodiment, before determining multiple target links from multiple fiber optic links based on the power supply risk index corresponding to each fiber optic link, the method further includes: determining the power supply route length, fiber bending sensitivity, and geological risk index corresponding to each of the multiple fiber optic links, wherein the fiber bending sensitivity is used to represent the degree of influence of the bending state of the fiber in the corresponding fiber optic link on the transmission loss of light, and the geological risk index is used to represent the degree of influence of geological features on the power supply stability of the corresponding fiber optic link; and determining the power supply risk index corresponding to each of the multiple fiber optic links based on the power supply route length, fiber bending sensitivity, and geological risk index.

[0076] This involves the length of the power supply route, which is the length of the corresponding optical fiber link from the power supply end to the target base station. Its value directly affects the attenuation and power supply efficiency during optical energy transmission.

[0077] This involves fiber bending sensitivity, which is a characteristic parameter that quantifies the increase in optical signal energy loss caused by microstructural deformation of optical fiber in a bent state. The larger the value, the worse the fiber's tolerance to bending deformation, and the transmission loss increases sharply as the bending radius decreases.

[0078] This includes a geological risk index, which is a quantitative index derived from the geological characteristics of the area where the fiber optic link is located. It is used to assess the potential impact of geological conditions on the stability of fiber optic power supply, and the higher the value, the greater the power supply risk at the geological level.

[0079] This involves optical transmission loss, which is the energy attenuation caused by factors such as the material, length, and bending state of the optical fiber when the optical signal is transmitted in the optical fiber, directly affecting the effective transmission efficiency of the power station's output energy.

[0080] This involves geological features, which are characteristics used to reflect geographical conditions such as topography, soil type, slope, hydrological conditions, and historical disaster occurrences along the fiber optic link.

[0081] This includes power supply stability, which refers to the ability of the fiber optic link to continuously and stably transmit energy to the target base station within a certain period of time.

[0082] The power supply route length can intuitively reflect the distance of optical fiber transmission and quantify the direct impact of distance on energy attenuation. Bending sensitivity can accurately measure the degree of optical transmission loss caused by the bending state of the optical fiber. The geological risk index can objectively assess the potential interference of geological features along the route on the continuity and stability of power supply. Therefore, by comprehensively considering the power supply route length, bending sensitivity, and geological risk index of each optical fiber link, the power supply risk level of each link can be fully quantified from multiple dimensions, avoiding misjudgment of risk due to assessment of a single factor, and providing an analytical basis for subsequent screening of low-risk target links.

[0083] Based on the above embodiments and optional embodiments, an optional implementation method is provided, which is described in detail below.

[0084] In related technologies, when a power supply station provides fiber optic power to a base station, a fiber optic power supply strategy needs to be determined to meet the base station's operational requirements. However, in these technologies, there is a technical problem where the determined fiber optic power supply strategy is inaccurate, leading to unreliable power supply to the base station.

[0085] There is currently no effective solution to the above problems.

[0086] In view of this, an optional embodiment of the present invention provides a method for determining the optical fiber power supply strategy of a base station, which can effectively solve the above-mentioned technical problems.

[0087] Figure 2 This is a flowchart of a method for determining the fiber optic power supply strategy of a base station in an optional embodiment of the present invention, such as... Figure 2 As shown, a detailed description follows.

[0088] S1, acquire energy supply data from the energy supply station and energy consumption data from the target base station;

[0089] Specifically, the total fiber optic data (i.e., power supply data and power consumption data) is obtained. The total fiber optic data includes the energy optical power allocated by the central station (i.e., the power supply station) to the target base station (hereinafter referred to as the base station), the fiber optic laying length, the fiber bending sensitivity, the geological risk score, the location of the base station and the key equipment inside the base station, the rated capacity of the base station battery and the current power consumption as a percentage of its rated capacity.

[0090] Before acquiring the power supply data of the power supply station and the power consumption data of the target base station, the process also includes collecting total fiber optic data. Specifically, this includes: deriving the optical power allocated from the central station to the base station from the central station's transmission control system, network planning tools, or energy management system; obtaining the fiber optic laying length by measuring the fiber segment length and event location using an optical time-domain reflectometer; generating a corresponding loss mapping table by comparing the fiber optic production parameter curve with the standard bending test on the test section to obtain the fiber optic bending sensitivity; obtaining slope, soil vulnerability, historical disaster frequency, and hydrological exposure based on geological disaster databases, geological survey reports, digital elevation models (DEM) / slope calculations, lidar (LiDAR) point clouds, historical disaster event statistics, and remote sensing and synthetic aperture radar inversion to obtain a geological risk score; obtaining the base station location and the set of key equipment inside the base station based on the operation management database, base station technical files, design schemes, and on-site inventory; and obtaining the base station battery's rated capacity and the current power level relative to its rated capacity based on the base station power management system or on-site battery measurements.

[0091] S2, determine multiple optical fiber links corresponding to the target base station, wherein the multiple optical fiber links are connected between the power supply station and the target base station, and the multiple optical fiber links correspond to different power supply risk indices;

[0092] Specifically, multiple fiber optic links corresponding to the target base station can be determined through a weighted network diagram. The weighted network diagram can be constructed based on the total fiber optic data. The weighted network diagram includes nodes consisting of a central station (i.e., a power supply station), base stations (i.e., the target base station), and candidate relay points (i.e., relay stations), as well as edges consisting of fiber optic laying routes between nodes.

[0093] Furthermore, segmented power replenishment and optimized transmission loss can be achieved through relay candidate points. The relay candidate points can be determined in the following way: according to the edge weights of each edge in the weighted network graph, the edges with edge weights less than a preset threshold are set as relay candidate points, and a set of relay candidate points (i.e., multiple relay stations) is obtained.

[0094] S3. Based on the power supply risk index corresponding to each of the multiple optical fiber links, determine multiple target links from the multiple optical fiber links. Among them, the multiple target links are optical fiber links whose power supply risk index is less than the power supply risk threshold.

[0095] Optionally, before determining multiple target links from multiple fiber optic links based on their respective power supply risk indices, the method further includes: determining the power supply route length, fiber bending sensitivity, and geological risk index corresponding to each of the multiple fiber optic links. The fiber bending sensitivity represents the impact of the fiber bending state on the light transmission loss, and the geological risk index represents the impact of geological features on the power supply stability of the corresponding fiber optic link. The power supply risk index corresponding to each of the multiple fiber optic links is determined based on the power supply route length, fiber bending sensitivity, and geological risk index, and can be specifically determined using the following formula:

[0096]

[0097] in, For the first Edge (i.e., the first) The edge weight (i.e., the power supply risk index) of a fiber optic link. This is the weighting adjustment coefficient; For the normalized first The length of the fiber optic cable laid along the edge (i.e., the length of the power supply route). The bending sensitivity of the optical fiber (i.e., the bending sensitivity of the optical fiber) is mapped to [0,1]. For the normalized first Geological risk score (i.e., geological risk index) of the strip edge. For the normalized first The deployment or maintenance cost of the stripe; For the normalized first The maintenance efficiency (i.e., the ease of maintenance) of the strip.

[0098] A larger value indicates a longer distance, and the cost should be increased accordingly. A larger value indicates more severe bending, leading to higher degradation and maintenance risks; A higher value indicates a higher geological risk; A higher value indicates a higher cost; This translates ease of maintenance into a positive contribution to the cost.

[0099] Furthermore, the weighted network diagram is a weighted network diagram with a geological risk score, which is obtained by weighting and summing the slope index, soil vulnerability index, frequency of historical disaster events, and hydrological exposure index of the area where the edge is located.

[0100] Specifically, the data with different dimensions are uniformly normalized using a minimum-maximum (min-max) normalization mapping to [0,1]. The geological risk score is formed by weighted summation of four sub-indicators within the region containing the edge. Based on the Geographic Information System (GIS) environment, slope calculations are performed on the digital elevation model, and the slope index of the area where the edge is located is obtained after normalization. The edge is projected onto the geological map / soil distribution map to obtain the main soil or stratum types on the edge. If the edge spans multiple types, the main type is selected by area weighting or a weighted average is calculated, and the soil type is mapped and normalized to a soil vulnerability index through a soil vulnerability comparison table. Historical disaster events (such as landslides, debris flows, ground fissures, and collapses) are geocoded spatially and point / polygon features are established. A buffer zone is set around each edge, and the number of events within the selected time window in the buffer zone is counted to obtain the frequency of historical disaster events. The rainfall intensity index per unit time is calculated from meteorological stations or return period analysis. The drainage capacity index of the watershed or edge unit is calculated. If the drainage capacity is poor, the exposure is higher. The minimum distance to the main water body / channel is calculated. The closer the distance, the higher the exposure. After weighted combination and normalization, the hydrological exposure index is obtained.

[0101] S4, determine the relay stations corresponding to multiple target links respectively, wherein the corresponding relay stations are used to assist the power supply station in providing fiber optic power to the target base station;

[0102] S5, determine the auxiliary power supply corresponding to each of the multiple relay stations, wherein the corresponding auxiliary power supply is the power supply of the relay station to the target base station for fiber optic power supply, and the multiple relay stations correspond one-to-one with the multiple target links.

[0103] Optionally, determining the auxiliary power supply corresponding to each of the multiple relay stations includes: for any one of the multiple relay stations, determining the auxiliary power supply corresponding to that relay station using the following method: determining the power loss index and multiple auxiliary power supply methods corresponding to that relay station, wherein the power loss index represents the degree of power loss when any relay station supplies fiber power to the target base station; determining the initial power supply corresponding to that relay station based on the power loss index; determining the power enhancement index corresponding to each of the multiple auxiliary power supply methods; and determining the auxiliary power supply corresponding to that relay station based on the initial power supply and the power enhancement index corresponding to each of the multiple auxiliary power supply methods.

[0104] Optionally, determining the initial power supply corresponding to any relay station based on the power loss index includes: determining the power transmission index corresponding to any relay station based on the power loss index, wherein the power transmission index is used to represent the power transmission level of any relay station; determining the allocated power of the power supply station to the target base station; and determining the initial power supply corresponding to any relay station based on the power transmission index and the allocated power.

[0105] Specifically, multiple auxiliary power supply methods can be represented by the overlap type of relay candidate points. For example, based on the edge weights (i.e., power supply risk index) of each edge in the weighted network graph, edges with edge weights less than a preset threshold are set as relay candidate points, and a set of relay candidate points is obtained. All relay candidate points (i.e., multiple relay stations) in the relay candidate point set are classified by overlap type. The overlap type (i.e., multiple auxiliary power supply methods) includes deep physical overlap, functional resource overlap, sensor coupling overlap, and basic no overlap. Deep physical overlap refers to the relay station and the base station's key equipment being physically co-located; functional resource overlap refers to the relay station and the base station's key equipment having the ability to be physically separated, but achieving strong coupling at the functional or resource level; sensor coupling overlap refers to the relay station primarily carrying out monitoring and rapid detection functions, and achieving coupling with the base station's key equipment in terms of sensing data.

[0106] For example, on a weighted network graph G(V,E) with geological risk scoring, based on the edge weight of each edge, a preset number of physically feasible installation locations are selected from the edges of the graph and the facility points on the edges (such as manholes, machine rooms, maintenance wells, and road access points) as relay candidate points to establish a relay candidate point set. When the edge weight is less than a preset threshold, filtering is performed first, that is, if the geological risk of the relay candidate point exceeds the allowable upper limit, it is removed. If the distance between the relay candidate point and the existing candidate point is less than the preset minimum distance, they are merged into a single candidate point and the better one is retained. If there is no maintenance road or power access at the relay candidate point and it cannot be resolved in the short term, it is marked as low priority or removed, thus obtaining the relay candidate point set.

[0107] Furthermore, Deep Physical Overlap (Type-A): Relay stations and base station critical equipment are physically co-located. Feasibility conditions: The candidate relay point is adjacent to the base station or located within the base station equipment room; the geological risk score is below the danger threshold. If these conditions are met, Type-A will be considered as one of the overlap types for the candidate relay point.

[0108] Functional resource overlap (Type-B): Decision criteria: There is a short-distance connection between the candidate point and the base station or resource sharing is achieved through a low-cost line;

[0109] Sensor Coupling Overlap (Type-C): Decision criteria: Candidate points can be equipped with distributed fiber optic sensors or connected to existing sensor links, and have data backhaul capabilities.

[0110] When the power loss index is equal to the total optical loss, the power loss index corresponding to any relay station is determined by the following formula:

[0111]

[0112] in, The total optical loss from relay candidate point r to base station k; The fiber attenuation coefficient; Let r be the total path length from relay candidate point r to base station k; The set of bending points on the path; The loss at the l-th bending point; For the set of connectors on the path; Let be the loss of the c-th connector.

[0113] When the power transfer index is linear, the efficiency reaches its destination. In this case, the power transmission index corresponding to any relay station is determined based on the power loss index, using the following formula:

[0114]

[0115] in, The linear arrival efficiency from relay candidate point r to base station k is denoted by 0-1, representing the proportion of optical power from the transmitting end (i.e., the power supply station) to the base station (i.e., the target base station).

[0116] When the initial power supply is the electrical power used for charging or supplying power at the base station, the initial power supply corresponding to any relay station is determined based on the power loss index, using the following formula:

[0117]

[0118] in, The electrical power used for charging or supplying power at the base station; The transmit power allocated to base station k by the central station (that is, the power allocated by the power supply station to the target base station). The photoelectric conversion efficiency at the base station is set to a value of 0-1, depending on the receiver type and operating wavelength.

[0119] When the auxiliary power supply is equal to the arriving power, the auxiliary power supply corresponding to each of the multiple relay stations is determined based on the initial power supply and the power enhancement index corresponding to each of the multiple auxiliary power supply methods. The formula is as follows:

[0120]

[0121] in, Let x be the arriving electrical power (i.e., auxiliary power) of base station k when the relay candidate point adopts the overlapping type (i.e., auxiliary power supply method). The overlap correction factor (i.e., the power enhancement index) represents the equivalent energy gain resulting from different overlap types.

[0122] For example, The total optical loss (dB) is from relay candidate point r to base station k. , is the fiber attenuation coefficient (dB / km), which is determined by the fiber type and wavelength; Let r be the total path length (km) from relay candidate point r to base station k. The loss (dB) at the l-th bending point can be obtained from the bending loss curve or from the field measurement table. For cases using the minimum bending radius, the bending loss can be determined by empirical expressions or by looking up tables. The loss (dB) of the c-th connector; To convert dB loss into a linear proportional dimensionless (0-1); The photoelectric conversion efficiency at the base station is set to a value of 0-1, which is determined by the receiver type, the efficiency of the optoelectronic device, and the maximum power point tracking (MPPT) strategy. The overlap correction factor represents the equivalent arrival energy improvement brought about by different overlap types. Specifically, it represents the multiple of the actual usable electrical power at the base station when the overlap type x is used at the relay candidate point, compared to the case without overlap. The base is none, meaning there is no overlap. For Type-A: 1.2-1.4 (examples demonstrating that measures such as co-location deployment, reduced connectors and bends, and improved reception and shared buffers can result in a significant increase in arrival power). For Type-B: 1.05–1.2 (example, indicating a moderate improvement through feature sharing and partial coupling); For Type-C: , Very small (example 0.01–0.05; sensor coupling mainly improves monitoring and decision-making accuracy, but has limited direct improvement on instantaneous power). and The actual calibration was performed by conducting comparative experiments on a predetermined number of representative candidate points (measuring the arriving optical power and converted electrical power at the base station for non-overlapping and overlapping schemes under the same center transmit power), and the actual calibration was directly calculated from the measured data. ; The power of non-overlapping electrical power is based on the overlap type; Let x be the electric power of the overlapping type.

[0123] S6 determines the fiber optic power supply strategy corresponding to the target base station based on power supply data, power consumption data, and the auxiliary power supply power of multiple relay stations.

[0124] Optionally, based on power supply data, power consumption data, and the auxiliary power supply power corresponding to each of the multiple relay stations, a fiber optic power supply strategy corresponding to the target base station is determined, including: determining the total power corresponding to the target base station based on the auxiliary power supply power corresponding to each of the multiple relay stations; determining the power consumption parameters and equipment weight index corresponding to each of the multiple electrical devices, wherein the equipment weight index is used to represent the importance of the corresponding electrical device, and the target base station includes multiple electrical devices; determining multiple first operating durations corresponding to the target base station based on the total power supply, and the power consumption parameters and equipment weight index corresponding to each of the multiple electrical devices, wherein the multiple first operating durations correspond one-to-one with the multiple relay stations; and determining the fiber optic power supply strategy corresponding to the target base station based on the power supply data, power consumption data, and the multiple first operating durations.

[0125] Specifically, the total electrical energy corresponding to the target base station is determined based on the auxiliary power supply power of each of the multiple relay stations. The formula is:

[0126]

[0127] in, To within the selected time window Internal base station The total electrical energy obtained includes current battery energy and an estimate of future energy arrival; For base stations The proportion of current electricity consumption to its rated capacity; For base stations The rated capacity of the battery.

[0128] Based on the total electrical energy, as well as the power consumption parameters and equipment weight index of each electrical device, multiple first operating durations corresponding to the target base station are determined. The formula is:

[0129]

[0130] in, Let be the energy processing time of base station k when using overlap type x, representing the duration of operation while maintaining only the minimum power consumption of critical equipment; This is the set of key equipment for base station k; The power consumption parameter of the i-th critical device (i.e., the electrical device) is used to represent the power consumption of the i-th critical device in the lowest acceptable operating mode. This represents the proportion of critical equipment i in the critical support energy allocation during critical support scheduling (i.e., the equipment weight index).

[0131] Based on power supply data, power consumption data, and multiple first operating durations, the fiber optic power supply strategy corresponding to the target base station is determined. This also includes determining the duration gain corresponding to each of the multiple first operating durations. The formula for determining the duration gain corresponding to each of the multiple first operating durations is as follows:

[0132] ;

[0133] in, This refers to the duration gain when using overlapping type x; This represents the energy processing time when using an overlapping type as the basis for a non-overlapping type.

[0134] For example:

[0135] This includes the current battery capacity and the electrical energy expected to arrive and be available within the time window;

[0136] Dimensionless, with a value range of (0-1);

[0137] The proportion of critical equipment i in the critical support energy allocation during critical support scheduling is expressed as:

[0138]

[0139] in, The criticality (i.e. importance) weight of critical device i is defined according to the operating scenario; This is the set of key equipment for base station k.

[0140] Optionally, based on power supply data, power consumption data, and multiple first operating durations, a fiber optic power supply strategy corresponding to the target base station is determined, including: based on multiple first operating durations, determining auxiliary gain indices corresponding to multiple relay stations respectively, wherein the corresponding auxiliary gain index is used to represent the degree to which the corresponding relay station assists in reducing the operational risk of the target base station; and based on power supply data, power consumption data, and auxiliary gain indices corresponding to multiple relay stations respectively, a fiber optic power supply strategy corresponding to the target base station is determined.

[0141] Based on multiple first runtimes, determine the auxiliary gain index corresponding to each of the multiple relay stations. (That is, the risk-reward ratio, which represents the degree to which the corresponding relay station helps reduce the operational risk of the target base station), the formula is:

[0142] ;

[0143] in, For the corresponding first runtime, the auxiliary gain exponent of the relay candidate point r; Let r be the expected energy gain brought by the relay candidate point and k be the base station. The deployment cost at relay candidate point r; Additional costs incurred to mitigate geological risks or due to the deployment of relay candidate points; The comprehensive benefit ratio brought by relay candidate point r to base station k is used to represent the quantitative ratio between the benefits brought by relay candidate point r to base station k, such as improved power supply stability, extended emergency response time, and reduced risk, and the cost and risks required to deploy relay candidate point r.

[0144] Optionally, based on power supply data, power consumption data, and the auxiliary gain index corresponding to each of the multiple relay stations, a fiber optic power supply strategy corresponding to the target base station is determined, including: determining the usage index corresponding to each of the multiple relay stations based on the auxiliary gain index corresponding to each of the multiple relay stations, wherein the corresponding usage index indicates the degree to which the corresponding relay station is used for auxiliary fiber optic power supply; and determining the fiber optic power supply strategy corresponding to the target base station based on power supply data, power consumption data, and the usage index corresponding to each of the multiple relay stations.

[0145] Specifically, when the fiber optic power supply strategy includes a final set of candidate relay points, the usage index corresponding to each of the multiple relay stations is determined based on the overlap benefit index and the risk-benefit ratio to obtain the final set of candidate relay points. The overlap benefit index represents the benefit ratio between the emergency response time gain and the additional cost brought to the base station by the candidate relay point under the corresponding overlap type; that is, the additional emergency operation time gained for the base station for each unit of cost invested. Further, based on the risk-benefit ratio, the usage index corresponding to each of the multiple relay stations is determined, the candidate relay points are ranked, and the overlap type is selected for the candidate relay points based on the overlap benefit index. The overlap benefit index is determined by the following formula:

[0146]

[0147]

[0148] in, This is an overlap benefit index for base station k, relay candidate point r, and overlap type x. The higher the value, the more significant the time gain in exchange for the investment cost. Additional costs for overlapping type x include installation, interlocking, isolation, and long-term maintenance premiums; To weight the relay candidate point r across the entire network ; Let r be the set of base stations that benefit from relay candidate point r; The weighting coefficients for base station k; This is the comprehensive revenue indicator for base station k.

[0149] Furthermore, Benefit metrics including path reliability Indicators of revenue from information value Benefit metrics for savings in operation and maintenance costs and recovery costs ; This includes gains in path reliability and gains in maintenance and recovery cost savings; path reliability is the availability of base station k through relay candidate point r under overlap type x; information value is the value of sensor coupling measured using information theory indicators; maintenance and recovery cost savings are the annual maintenance and recovery cost savings brought about by overlap type x.

[0150] Sure The formula is:

[0151]

[0152] in, This represents the additional cost corresponding to the overlapping type x.

[0153] The revenue metric for path reliability can be represented by the availability (expected online probability within a specified time window) of base station k via relay candidate point r under overlap type x, taking a value of (0-1). Specifically, it is determined by the following formula:

[0154]

[0155]

[0156] in, This represents the path failure probability (overlapping reduces the failure probability). This represents the probability of path failure when there is no overlap, and its value is (0-1). The value is (0-1) representing the relative reduction rate of the failure probability due to overlap.

[0157] For example, Type-C corresponds to The values ​​are larger (the sensors have the ability to detect risks early); Type-A and Type-B also reduce the value by different amounts through physical stabilization or easy maintenance.

[0158] So, the gain in path reliability It can be determined using the following formula:

[0159]

[0160] Here, none indicates a non-overlapping type.

[0161] For the revenue indicators of information value Information gain, represented by , can be determined in the following way:

[0162] Let the entropy of the prior path states be... The posterior entropy after sensor observation is , The formula for determining it is:

[0163]

[0164] in, The larger the value, the more helpful it is in reducing uncertainty, the more accurate the operation (pre-charging or triggering mobile relay), and the less additional cost caused by misjudgment; Significantly higher and The value of sensor coupling can be measured using information theory metrics.

[0165] Benefit metrics for savings in operation and maintenance costs and recovery costs It can be determined in the following ways:

[0166] Overlapping type Annual maintenance and recovery cost savings The formula for determining it is:

[0167]

[0168] in, Downtime cost per unit hour; For overlapping type x, the equivalent maintenance man-hours or maintenance workload saved by the operation and maintenance during the evaluation period; The maintenance cost per unit of maintenance man-hours (or unit of maintenance quantity).

[0169] Sure The formula is:

[0170]

[0171] in, The set of base stations that can benefit from relay candidate point r (i.e., the range of base stations that relay candidate point r can serve). This is the value coefficient for reliability gain.

[0172] Specifically, and The specific descriptions of their dimensions are identical. With time window Internal relay candidate points Using overlapping type Compared to the non-overlapping condition for base stations The resulting expectation is that the incremental power output can be used as the core definition, and factors such as the difference in power output, charging and discharging efficiency, management efficiency, and path availability factor can be adopted. The product of the products and the expected value; For all costs of construction / equipment / integration / testing that are one-time and can be amortized; Additional costs for reinforcement, protection, redundancy, inspection, and insurance required to reduce geological / operational risks.

[0173] When the fiber optic power supply strategy includes a final set of candidate relay points, the above steps can be implemented by determining the system through the fiber optic power supply strategy of the base station. Figure 3 This is a schematic diagram of the structure of the fiber optic power supply strategy determination system for a base station in an optional embodiment of the present invention, as shown below. Figure 3 As shown, the fiber optic power supply strategy determination system for this base station includes:

[0174] The data acquisition module is used to acquire total fiber optic data and construct a weighted network diagram with geological risk scoring based on the total fiber optic data.

[0175] The type classification module is used to obtain the set of relay candidate points based on the edge weights of each edge in the weighted network graph, and to classify the overlapping types of each relay candidate point.

[0176] The power calculation module is used to obtain the total optical loss and linear arrival efficiency from the relay candidate point to the base station, and, in combination with the overlap type, to obtain the arrival electrical power of the base station when the relay candidate point adopts different overlap types.

[0177] The time gain module is used to obtain the total electrical energy and energy processing time based on the total fiber data and the arriving electrical power, and to obtain the duration gain when using different overlap types.

[0178] The candidate point determination module is used to calculate the overlap benefit index and risk-reward ratio for relay candidate points and their corresponding overlap types, and to determine the final set of relay candidate points based on the overlap benefit index and risk-reward ratio.

[0179] The above optional implementation methods can achieve at least the following beneficial effects:

[0180] (1) Compared with related technologies, this invention can clearly identify the output capacity of the power supply head, the energy demand of the base station, and the risk differences of each link by acquiring the power supply data of the power supply station, the energy consumption data of the target base station, and multiple optical fiber links with different power supply risk indices between the power supply station and the target base station. On this basis, multiple target links with risks below the threshold are selected according to the power supply risk index, which can avoid the impact of high-risk links on the stability of power supply. Then, the relay stations corresponding to these target links are determined one by one, which can make up for the loss of link transmission and strengthen the continuity of power supply by using the auxiliary role of the relay stations. Furthermore, the auxiliary power supply power corresponding to each relay station is determined, which can accurately match the power supply supplement intensity of each link and ensure that the power supply output is adapted to the link demand. Finally, by combining the power supply data, energy consumption data, and auxiliary power supply power of each relay station, the optical fiber power supply strategy adapted to the base station can be accurately determined, thereby improving the power supply reliability of the target base station. This solves the technical problem in related technologies where the determined optical fiber power supply strategy is inaccurate, leading to unreliable power supply to the base station.

[0181] (2) Compared with related technologies, this invention quantifies the degree of energy transmission loss by clearly defining the power loss index corresponding to any relay station, and then determines the initial power supply to compensate for the basic transmission loss based on the loss index. Next, it clarifies the power enhancement index corresponding to different auxiliary power supply methods to grasp the power enhancement effect of each method. Finally, it accurately calculates the auxiliary power supply of any relay station by combining the initial power supply and the power enhancement index. This takes into account both the inherent loss of the link and the gain effect of auxiliary power supply, and can ensure that the auxiliary power supply of each relay station is accurately matched with the loss characteristics and power supply requirements of the corresponding target link. This provides reliable power parameter support for the subsequent formulation of accurate optical fiber power supply strategies, thereby solving the technical problem of unreliable base station power supply caused by inaccurate power supply strategies in related technologies.

[0182] (3) Compared with related technologies, this invention can determine the power transmission index to clarify the power transmission efficiency from the relay station to the target base station. It uses the power allocation planned by the power supply station for the target base station as the basic reference benchmark and combines the two to determine the initial power supply of any relay station. This allows the initial power supply to adapt to the link transmission characteristics, compensate for inherent losses, and fit the overall power supply plan of the power supply station. This ensures that the calculation of the initial power supply is accurate and reasonable, and provides a data foundation for the subsequent accurate determination of the optical fiber power supply strategy.
