[0055] In this embodiment, the integrated system diagram is a comprehensive display of the entire wireless communication system, including all components, connecting lines, data flows, and control signal paths, providing an overall view of the system. For example, in the integrated system diagram of a wind farm, the layout of macro base stations, micro base stations, and small base stations can be seen. The connecting lines identify the transmission paths of data flows and control signals, showing how to achieve efficient wireless communication through optimized configuration.

[0056] The working principle and beneficial effects of the above technical solution are: by obtaining user needs and clarifying expected functions, formulating basic performance indicators, collecting site terrain and environmental data, identifying potential interference sources, building infrastructure, dividing areas according to coverage requirements and drawing network topology maps, ensuring signal coverage in each area, combining the infrastructure with the network topology map to form a comprehensive system map, thereby improving the signal coverage of new energy sites, ensuring the stability of data transmission, and improving user satisfaction and the system's adaptability and reliability in complex environments.

[0057] Embodiment 2:

[0058] The embodiment of the present invention provides a new energy station vehicle-mounted wireless communication system, an indicator module, including:

[0072] Constructing a framework unit: determining a component list of a basic framework based on the site characteristics and basic performance indicators, and determining a basic framework based on the component list and potential interference sources.

[0073] In this embodiment, external objects refer to objects located outside the new energy station, which may affect signal propagation, such as high-voltage towers or buildings outside a wind farm; the process of identifying external objects is to identify external objects in the surrounding environment through data analysis and sensor technology, such as using lidar or image recognition technology to scan the surrounding environment and identify high-voltage towers and other obstacles.

[0074] In this embodiment, internal objects refer to objects located inside the new energy station, which are entities that may affect signal propagation, such as substation equipment or energy storage systems in solar power stations; the process of identifying internal objects is to identify objects inside the new energy station through sensors and data analysis, for example, using sensors to detect the location and layout of power generation equipment, thereby identifying internal transformers and control equipment.

[0075] In this embodiment, the main obstruction feature refers to the main object features that affect signal propagation, such as height, material, shape, etc. For example, the metal structure and height of a high-voltage tower may cause severe signal attenuation.

[0076] In this embodiment, the wireless signal propagation model is a mathematical model used to simulate the propagation characteristics of wireless signals in a specific environment. For example, the Hata model or the COST-231 model is used to predict the propagation of signals in a complex terrain of a wind farm.

[0077] In this embodiment, the attenuation effect refers to the intensity loss of the signal caused by obstacles during the propagation process. For example, in a solar power station, buildings may cause signal attenuation of 10-20 dB.

[0078] In this embodiment, the component list is a list of all components required in the infrastructure, including hardware and software. For example, the component list of the vehicle-mounted wireless communication system may include an antenna, a transmitter, a receiver, and a signal processing unit.

[0080] Embodiment 4:

[0081] The embodiment of the present invention provides a new energy station vehicle-mounted wireless communication system, a topology module, including:

[0082] Demand graph unit: Identify different application scenarios in the new energy station, clarify the communication requirements corresponding to each application scenario, predict user traffic requirements in different time periods based on the historical traffic data of the new energy station, derive coverage requirements based on the scenario requirements and user traffic, and draw a demand graph;

[0083] Area division unit: divides the new energy station into multiple coverage areas by using a space division method according to the basic framework and the coverage requirements;

[0084] A combination determination unit: randomly combining macro base stations, micro base stations and small base stations of vehicle-mounted wireless communication within the coverage area according to the coverage requirements, using a simulation tool to perform position simulation on the random combinations based on the coverage requirements and potential interference sources in the corresponding coverage area, and screening the random combinations to obtain candidate combinations in each coverage area;

[0085] Topology unit: Determine the network topology of the new energy station by comprehensively considering all the candidate combinations corresponding to the coverage areas, and draw the network topology map in combination with the demand map.

[0086] In this embodiment, the application scenarios are different usage scenarios in the new energy station, which may involve specific functions or requirements, such as monitoring systems, equipment maintenance, data transmission and user access in wind farms.

[0087] In this embodiment, the communication requirement is the communication capability required for each application scenario, including indicators such as bandwidth, latency, and reliability. For example, a real-time monitoring system may require low latency and high bandwidth to ensure timely data transmission.

[0088] In this embodiment, the historical traffic data is the user traffic information of the new energy station in the past period of time, which is used for analysis and prediction, for example, the user access volume and data transmission volume records of the wind farm in different seasons and time periods.

[0089] In this embodiment, the user traffic demand is estimated based on historical traffic data and prediction models to estimate the number of users and traffic demand in different time periods in the future. For example, during the peak period of the wind farm, it is expected that 100 users will access simultaneously, and the traffic demand will reach 500MB.

[0090] In this embodiment, the demand graph is a diagram drawn based on application scenarios and user traffic requirements, showing the communication requirements of different areas. For example, high-demand areas: wind turbine areas (marked in red), require high bandwidth and low latency; medium-demand areas: substation areas (marked in yellow), require medium bandwidth; low-demand areas: office areas (marked in green), have relatively low demands.

[0091] In this embodiment, the spatial division method is a technology or algorithm for dividing a new energy site into a plurality of coverage areas, for example, using a grid division method to divide a wind farm into a plurality of uniform coverage areas.

[0092] In this embodiment, the random combination is a random configuration of different types of base stations (macro base station, micro base station, small base station) within the coverage area. For example, there is one macro base station, covering the entire site; three micro base stations, located in the wind turbine area, substation and office area respectively; and five small base stations, distributed in small areas with high demand.

[0093] In this embodiment, the macro base station, micro base station and small base station for vehicle-mounted wireless communication are base stations of different sizes and functions, which are used to provide wireless signal coverage of different ranges and intensities. For example, the macro base station is located on the high ground of the wind farm, covering the entire site; the micro base station is installed on the substation and specifically serves the equipment monitoring of the substation; the small base station is deployed in the office area and near the wind turbine to support mobile communications for on-site staff.

[0094] In this embodiment, the simulation tool is a software tool used to simulate and analyze wireless signal propagation and its performance in a specific environment. For example, simulation tools such as MATLAB or NS-3 are used to evaluate the signal coverage effect of a base station combination. Location simulation is to simulate the impact of base station location on signal coverage in a simulation tool, for example, to simulate the signal strength and coverage range of different base station location combinations in a wind farm.

[0095] In this embodiment, the process of screening the random combination is to evaluate and select the optimal base station combination based on the simulation results. For example, through the simulation results, the signal coverage, interference and throughput of different base station combinations are compared to select the combination with the best signal strength and the least interference.

[0096] In this embodiment, the network topology is a network structure diagram designed based on the selected combination and coverage area. For example, the macro base station is located in the center of the site, and the micro base station and small base station are distributed in various high-demand areas to form a star structure; the network topology diagram is a visualized network topology that displays the location, coverage area and connection relationship of the base station. For example, in the network topology diagram of the wind farm, the location and coverage range of the macro base station, micro base station and small base station are identified.

[0097] The working principle and beneficial effects of the above technical solution are: by dividing the site into multiple coverage areas, setting coverage priorities and determining key areas, randomly combining base stations, using simulation tools to screen candidate combinations, integrating all candidate combinations, and drawing a network topology map to optimize wireless communication coverage and ensure stable operation of the communication system in a complex environment.

[0098] Embodiment 5:

[0099] An embodiment of the present invention provides a new energy station vehicle-mounted wireless communication system, a combination determination unit, including:

[0100] Simulation block: defines the base station parameters corresponding to the macro base station, micro base station and small base station of vehicle-mounted wireless communication, uses a random algorithm to generate different random combinations, performs position simulation based on the base station combination, and outputs the coverage effect of vehicle-mounted wireless communication simulated at each position;

[0101] Coverage satisfaction block: Determine the coverage satisfaction according to the coverage effect and coverage requirement, and take the random combination higher than the preset coverage satisfaction as the candidate combination.

[0102] In this embodiment, a random algorithm is used to generate a process of different base station combinations to ensure that the layout and configuration of the base stations are diverse, thereby exploring the best network design solution. For example, in a wind farm, the random algorithm can generate multiple base station configurations, such as: Combination 1: 1 macro base station (covering the entire site) + 2 micro base stations (located near the substation and wind turbine respectively) + 4 small base stations (distributed in high-demand areas), Combination 2: 1 macro base station + 3 micro base stations + 2 small base stations (concentrated in office areas).

[0103] In this embodiment, the coverage effect refers to the signal coverage range, strength and quality of the vehicle-mounted wireless communication system under a specific base station combination, which is usually evaluated through simulation tools. For example, after location simulation, the following coverage effects may be obtained: Coverage effect of combination 1: The signal strength reaches -70dBm in the wind turbine area and -65dBm in the substation area, meeting the high bandwidth requirements; Coverage effect of combination 2: The signal strength reaches -75dBm in the office area, but the signal strength in the wind turbine area is only -80dBm, which cannot meet the requirements.

[0104] In this embodiment, coverage satisfaction refers to the comparison result between the coverage effect and the preset coverage requirement, usually expressed as a percentage, reflecting the degree to which the base station combination meets the communication requirements. For example, assuming the preset coverage requirements are: wind turbine area: signal strength must be higher than -75dBm; substation area: signal strength must be higher than -70dBm; according to the simulation results: the coverage satisfaction of combination 1 is 100% (all areas meet the requirements); the coverage satisfaction of combination 2 is 50% (the wind turbine area does not meet the requirements).

[0105] The working principle and beneficial effects of the above technical solution are: by defining the parameters of macro base stations, micro base stations and small base stations, using random algorithms to generate different base station combinations, and performing location simulation, evaluating the wireless coverage effect of each combination, and based on the comparison of coverage effect and demand, screening out combinations that meet the preset coverage satisfaction, so as to optimize the wireless communication system of new energy sites, effectively improve signal coverage, reduce interference, meet communication needs in complex environments, thereby ensuring the reliability of real-time monitoring and data transmission, and promoting the efficient utilization and development of renewable energy.

[0106] Embodiment 6:

[0107] The embodiment of the present invention provides a new energy station vehicle-mounted wireless communication system, covering a satisfactory degree block, including:

[0108]

[0109] Where C(t) represents the coverage satisfaction in the coverage area at time t; |A| represents the area of ​​the coverage area; A represents the coverage area; P t represents the transmission power of a random combination within the coverage area at time t; L(x, y, t) represents the signal loss function at position (x, y) and time t; P j represents the transmission power of the jth potential interference source; j represents the index of the potential interference source; n represents the number of potential interference sources in the coverage area; L j (x, y, t) represents the signal loss function of the jth interference source at position (x, y) and time t; T represents the preset minimum signal strength threshold in the coverage area; U(x, y, t) represents the coverage requirement function corresponding to the coverage area at position (x, y) and time t.

[0110] The working principle and beneficial effects of the above technical solution are: by defining parameters such as coverage satisfaction, coverage area, transmission power, signal loss function and interference source, the signal coverage at a specific time and location is evaluated, and different base station configurations are generated using random combinations. The coverage satisfaction is calculated and compared with the preset threshold to screen out the combination that meets the needs, so as to optimize the wireless communication performance of the new energy station and ensure stable data transmission.

[0111] Embodiment 7:

[0112] An embodiment of the present invention provides a new energy station vehicle-mounted wireless communication system, a topology unit, including:

[0113] Analyze the signal overlap between candidate combinations of different coverage areas, and evaluate the mutual influence between different candidate combinations based on the signal overlap, and perform mobile adjustment on the candidate combinations according to the mutual influence to obtain a base station combination;

[0114] A multi-level network architecture is set up based on the base station combination, and a network topology diagram is drawn in combination with the demand diagram.

[0115] In this embodiment, the signal overlap situation refers to the degree of overlap of signal strengths within the coverage areas of different base stations, reflecting the situation where multiple base stations provide signals at the same location. For example, in a wind farm, the overlapping part of the coverage areas of base station A and base station B can provide stronger signal strength, ensuring stable communication in the key monitoring area of ​​the wind farm.

[0116] In this embodiment, the mutual influence is the signal interference or enhancement effect between different candidate base station combinations, which evaluates how the signal of one base station affects the coverage of another base station. For example, in a solar power station, the signal strength of base station C may interfere with the signal of base station D, causing the latter's coverage to decrease in certain areas.

[0117] In this embodiment, the process of mobile adjustment is to optimize the position of the selected base station based on the evaluation results of signal overlap and mutual influence to improve the overall coverage effect. For example, if the signal overlap between base station E and base station F causes interference, the position of base station F may be slightly moved to reduce interference and improve signal coverage.

[0118] In this embodiment, the base station combination is the final base station configuration selected from the candidate combinations after analysis and optimization, which can meet specific coverage requirements and reduce signal interference. For example, in a wind farm, multiple candidate combinations may be generated, such as candidate combinations A, B, C and candidate combinations D, E, F, etc. Base station combination: After signal overlap and mutual influence analysis, the combination of candidate combinations A, C and E is finally selected as the base station combination.

[0119] In this embodiment, the multi-level network architecture is a network architecture constructed based on an optimized base station combination, which usually includes multiple levels of base stations to meet different coverage requirements. For example, in a wind farm, a main base station is set up to be responsible for the coverage of the core area, and several auxiliary base stations are set up to expand the coverage to the edge area, forming a multi-level network structure.

[0120] In this embodiment, the network topology map is a graphical representation of the base station location, coverage area and signal strength, which helps to visualize the network structure and signal coverage. For example, in the network topology map of the new energy station, the layout, signal strength and overlapping area of ​​the base stations will be marked to facilitate subsequent network management and optimization.

[0121] The working principle and beneficial effects of the above technical solution are: by analyzing the signal overlap between the candidate combinations of different coverage areas, evaluating the mutual impact, and then making mobile adjustments to the base station combination, a multi-level network architecture is established based on the optimized base station combination, and a network topology map is drawn in combination with the demand graph to ensure the effectiveness and reliability of signal coverage, reduce signal interference and coverage blind spots, and meet communication needs in complex environments.

[0125] In this embodiment, the location map shows the geographical locations and relative relationships of various components in the system (such as base stations, vehicle-mounted equipment, etc.). For example, in a wind farm, the macro base station may be located in the center of the site, the micro base station is distributed near each wind turbine, and the small base station is set on the driving path of the service vehicle to ensure signal coverage.

[0126] In this embodiment, data flow refers to the direction and content of information transmission in the system, which usually involves user data, monitoring information, etc. For example, in a solar power station, the real-time power generation data collected by the on-board equipment is transmitted to the central server through the micro base station for data analysis and monitoring.

[0127] In this embodiment, the control signal is used to manage and regulate operations between system components, such as starting and stopping the base station, frequency adjustment, etc. For example, in a wind farm, the control signal can be sent from the central control system to each base station, instructing them to adjust the signal strength or switch frequency bands according to real-time needs.

[0128] In this embodiment, the transmission path refers to the specific route through which data and control signals flow in the system, which usually involves the connection of multiple components. For example, in a solar power plant, the data transmission path may be: vehicle-mounted equipment → small base station → micro base station → macro base station → data center, ensuring the effective transmission of information.

[0129] The working principle and beneficial effects of the above technical solution are: by integrating macro base stations, micro base stations and small base stations, optimizing the base station combination to achieve optimal signal coverage, using random algorithms to generate different base station configurations, evaluating their signal coverage effects, and dynamically adjusting the base station position according to coverage satisfaction and signal interference, ensuring stable and efficient wireless communication services in complex environments, optimizing base station layout, significantly improving signal coverage in complex terrain, reducing blind spots, and improving communication quality and stability.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
