Description

Technical Field

[0001] The present invention relates to the technical field of communication networking collaborative control, and specifically to an air-ground integrated communication networking collaborative control method and system. Background Art

[0002] With the development of the economy, the coverage of the power grid continues to extend to remote areas, and the power grid structure is becoming increasingly complex, including a large number of transmission lines, substations and distributed energy resources. Ensuring reliable communication and effective monitoring of power grid equipment in remote areas has become a key issue. In the inspection of power lines in some mountainous areas, it is necessary to use advanced communication networking technology to realize automated monitoring methods such as drone inspection and transmit line status data in real time. Natural disasters (such as earthquakes, floods, typhoons, etc.) occur frequently, which can cause serious damage to ground communication infrastructure (such as base stations and optical fiber lines), resulting in power grid communication interruptions. In disaster emergency scenarios, rapid restoration of power grid communication is crucial for tasks such as power repair and ensuring power supply to key facilities. The rapid development of drone technology has provided a new means for air-ground integrated communication networking. Drones can be used as aerial communication platforms, carry communication equipment, and flexibly fly over the required areas to expand communication coverage. In the air-ground integrated communication networking, multiple communication systems and equipment are involved, such as aerial drones, high-altitude communication platforms, and ground base stations and sensor networks. These systems need to work together effectively to give full play to their respective advantages and achieve efficient operation of the overall communication network.

[0003] Nowadays, there are still some deficiencies in the research on the coordinated control of air-ground integrated communication networking. Specifically, in complex terrain environments, signal blocking, reflection, scattering and other phenomena frequently occur, forming multipath effects, resulting in reduced communication quality. Signal coverage is difficult, and the current dynamic response capabilities of communication links under complex terrain are insufficient. In addition, the intelligent fault diagnosis and self-healing capabilities are insufficient, and the intelligence level of air-ground integrated communication links is limited. Faults cannot be diagnosed quickly and accurately, and they still rely on manual intervention for troubleshooting and repair, resulting in longer communication interruptions and reduced network reliability, affecting the normal operation of power grid operations. Summary of the invention

[0019] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0020] (1) The present invention provides an air-ground integrated communication networking collaborative control method and system. When it is determined that the area to be analyzed is not a signal coverage difficulty area, the medium frequency band is selected for communication between the air layer and the ground layer. This has great advantages in meeting the requirements of high-speed data transmission. For areas with signal coverage difficulties, low frequency bands are used for communication, which can better penetrate obstacles and bypass complex terrain, such as mountains in mountainous areas and vegetation in forests.

[0021] (2) The present invention helps to improve the dynamic response capability of the communication link by determining the air-ground integrated communication threshold and the communication link transmission threshold of the area to be analyzed. The air layer status and the ground layer status of the area to be analyzed are analyzed separately, and the air layer communication status signal is combined with the ground layer status, which can more comprehensively and accurately reflect the communication status of the area to be analyzed, thereby providing a reliable basis for judging whether it is necessary to activate the emergency response plan. Analyzing the transmission status of the communication link in the area to be analyzed and promptly activating the backup communication link can avoid communication interruption, ensure that the monitoring data and control instructions of the power grid equipment can be continuously and stably transmitted, and maintain the safety and reliability of the power grid operation.

[0022] (3) The present invention obtains geographic environment data of the area to be analyzed, determines the air-ground integrated communication threshold and the communication link transmission threshold of the area to be analyzed, and determines whether the area to be analyzed is a signal coverage difficulty area. By obtaining geographic environment data to determine the communication threshold and determine the signal coverage difficulty area, communication networking planning can be carried out according to the actual conditions of different areas. Determining the signal coverage difficulty area can discover potential communication problems in advance to ensure effective coverage of the communication network. Determining the communication threshold can provide a quantitative standard for communication quality. The setting of the communication threshold will pay more attention to the dynamic response of the signal in different special scenarios, ensuring that basic communication functions can be achieved in special scenarios.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Reference Figure 1 As shown, the first aspect of the present invention provides a collaborative management and control method for air-ground integrated communication networking, including: acquiring geographical environment data of the area to be analyzed, determining the air-ground integrated communication threshold of the area to be analyzed and the communication link transmission threshold of the area to be analyzed, and judging whether the area to be analyzed is a signal coverage difficulty area: if the area to be analyzed is not a signal coverage difficulty area, considering the high-speed data transmission requirement, the communication frequency band between the aerial layer and the ground layer is the medium frequency band; if the area to be analyzed is a signal coverage difficulty area, considering the signal coverage range requirement, the communication frequency band between the aerial layer and the ground layer is the low frequency band.

[0029] The specific analysis process is as follows: obtaining geographic environment data of the area to be analyzed, which specifically includes the distance between the area to be analyzed and the central area, the humidity deviation rate of the area to be analyzed, and the altitude deviation rate of the area to be analyzed; based on the obtained geographic environment data of the area to be analyzed, a comprehensive analysis is performed to obtain the geographic environment analysis factor of the area to be analyzed, and the geographic environment analysis factor of the area to be analyzed is used as an analysis basis for determining the air-ground integrated communication threshold of the area to be analyzed and the communication link transmission threshold of the area to be analyzed; the geographic environment analysis factor of the area to be analyzed is stored as a designated label, and the designated label is compared with each set label stored in a database to obtain the set label corresponding to the designated label, and the air-ground integrated communication threshold of the area to be analyzed and the communication link transmission threshold of the area to be analyzed corresponding to the set label stored in the database are obtained.

[0030] The distance between the area to be analyzed and the central area refers to the geographic distance between the area to be analyzed (such as a remote mountainous area, suburbs or a specific power grid operation area) and the predefined central area (such as the city center, power grid control center or the location of the main communication hub). The farther the distance from the central area, the more marginal the area is in the communication network layout, and the lower the density, coverage and communication signal strength of the communication infrastructure will be. The humidity deviation rate of the area to be analyzed refers to the degree of difference between the current humidity of the area and the reference standard humidity, usually expressed as a percentage. The altitude deviation rate of the area to be analyzed refers to the degree of difference between the actual altitude of the area and the reference standard altitude, usually also expressed as a percentage. The deviation rate is the ratio of the absolute value of the difference between the actual value and the reference value to the reference value.

[0031] By obtaining the above three types of geographic environment data, the geographic environment characteristics of the area to be analyzed can be more comprehensively characterized. These factors are interrelated and influence each other, avoiding the situation where a single factor cannot fully reflect the complexity of the communication environment. For example, being far away from the central area means that the communication infrastructure is relatively weak, a high humidity deviation rate will affect the quality of signal propagation, and a high altitude deviation rate will cause problems such as signal blocking or reflection. Combining these factors to obtain the geographic environment analysis factor can more accurately evaluate the potential impact of the area on the communication network and provide a more reliable basis for determining the communication threshold.

[0032] When the area to be analyzed is a difficult area for signal coverage, the signal coverage range requirements need to be considered instead of high-speed data transmission. The geographical environment analysis factor is used as the analysis basis for determining the air-ground integrated communication threshold and the communication link transmission threshold of the area to be analyzed, making the setting of the communication threshold more refined. Different combinations of geographical environment analysis factors correspond to different communication conditions, so that the appropriate communication threshold can be customized for each area according to the actual situation.

[0033] In this embodiment, before all calculation formulas calculate corresponding values, corresponding parameters may be subjected to a homogenization process.

[0034] The specific analysis process of the regional geographical environment analysis factors to be analyzed is as follows:

[0035]

[0036] In the formula, δ is the geographical environment analysis factor of the area to be analyzed, jl is the distance between the area to be analyzed and the central area, sdp is the humidity deviation rate of the area to be analyzed, gdp is the altitude deviation rate of the area to be analyzed, μ 1 is the compensation factor of the set jl, μ 2 is the compensation factor of the set SDP, μ 3 is the compensation factor of the set GDP, and e is a natural constant.

[0037] The three factors of distance between the area to be analyzed and the central area, humidity deviation rate, and altitude deviation rate affect the performance of the communication link from different aspects, and the geographical environment analysis factor is calculated to comprehensively consider the comprehensive impact of the geographical environment on communication. The distance from the central area reflects the distribution of communication infrastructure and the potential loss of signal transmission; the humidity deviation rate affects the propagation quality of the signal in the air; and the altitude deviation rate involves signal shielding, reflection and other issues. According to the value of the geographical environment analysis factor, the communication frequency band between the air layer and the ground layer can also be reasonably selected.

[0038] It should be explained that the compensation factors of JL, SDP, and GDP set above are obtained from the database. According to the historical data, a mapping set of the historically measured distance between the area to be analyzed and the central area, the humidity deviation rate of the area to be analyzed, the altitude deviation rate of the area to be analyzed and the compensation factors of JL, SDP, and GDP are established to obtain the compensation factors of JL, SDP, and GDP corresponding to the current JL, SDP, and GDP.

[0039] It should be noted that the σ in the following text 1 , σ 2 , σ 3 , τ 1 , τ 2 , τ 3 , ε 1 , ε 2 , ε 3 They are also obtained through a mapping set of historical data and compensation factors established in a database, that is, the corresponding compensation factors are obtained according to the current data.

[0040] The geographic environment analysis factor of the area to be analyzed is compared with the geographic environment analysis threshold of the area to be analyzed stored in the database; if the geographic environment analysis factor of the area to be analyzed is not lower than the geographic environment analysis threshold of the area to be analyzed, the area to be analyzed corresponding to the geographic environment analysis factor of the area to be analyzed is not a difficult area for signal coverage, and considering the requirement of high-speed data transmission, the communication frequency band between the aerial layer and the ground layer is a medium frequency band; if the geographic environment analysis factor of the area to be analyzed is lower than the geographic environment analysis threshold of the area to be analyzed, the area to be analyzed corresponding to the geographic environment analysis factor of the area to be analyzed is a difficult area for signal coverage, and considering the requirement of signal coverage range, the communication frequency band between the aerial layer and the ground layer is a low frequency band.

[0041] When the geographic environment analysis factor of the area to be analyzed is not lower than the threshold, the communication frequency band between the air layer and the ground layer is selected as the mid-frequency band. This is because the mid-frequency band has significant advantages in meeting the requirements of high-speed data transmission. For example, in the mid-frequency band of 5G communication (such as around 3.5GHz), it can provide a higher data transmission rate and lower transmission delay. In such a relatively good communication environment, the characteristics of the mid-frequency band can be fully utilized to transmit a large amount of complex power grid data, such as high-definition video monitoring data (video of drone inspection of power grid equipment), real-time power grid equipment status monitoring data (including high-frequency data collection of many sensors), etc., effectively improving communication efficiency and meeting the requirements of power grid operation and management for timeliness and accuracy of data transmission.

[0042] If the geographic environment analysis factor is lower than the threshold, the area is judged as a difficult area for signal coverage, and low-frequency band communication is used. The propagation characteristics of low-frequency band signals enable them to have better coverage capabilities in complex terrain and environments. For example, low-frequency band signals around 700MHz have strong diffraction capabilities and can penetrate obstacles, bypass mountains or buildings, etc., effectively reducing signal blind spots. In places where signal coverage is difficult, such as remote mountainous areas, forest areas, or urban areas with tall buildings, low-frequency bands can guarantee basic communication coverage, ensure communication connections between power grid equipment and control centers, provide reliable communication support for power grid operations, and reduce the risk of communication failures due to insufficient signal coverage.

[0043] Communication resources can be reasonably allocated according to the characteristics of different regions to improve the adaptability of the communication system to various geographical environments.

[0044] The air layer status of the area to be analyzed is analyzed to obtain the air layer communication status signal of the area to be analyzed.

[0045] The specific analysis process is as follows: obtaining the aerial layer status data of the area to be analyzed, the aerial layer status data of the area to be analyzed specifically include the normal operation ratio of aerial layer UAVs, the remaining flight time of aerial layer UAVs, and the frequency of change of the altitude of aerial layer high-altitude communication platforms; based on the obtained aerial layer status data of the area to be analyzed, a comprehensive analysis is performed to obtain the aerial layer communication status signal of the area to be analyzed, and the aerial layer communication status signal of the area to be analyzed is used as the analysis basis for determining whether it is necessary to activate the emergency response plan.

[0046] The normal operation ratio of aerial drones refers to the ratio of the number of drones operating normally to the total number of drones in the aerial layer of the area to be analyzed. The remaining flight time of aerial drones refers to the average time that each drone can continue to fly under the current power, load and flight conditions. The frequency of change of the altitude of the high-altitude communication platform in the aerial layer refers to the ratio of the number of times the altitude of the high-altitude communication platform (such as balloons, airships, etc.) changes within a certain time range (such as one hour, one day) to the total observation time.

[0047] By acquiring a variety of status data, including the normal operation ratio of aerial layer drones, the remaining flight time, and the frequency of changes in the altitude of the high-altitude communication platform, the operation status of the aerial layer can be comprehensively depicted. These factors are interrelated, and a single factor cannot fully reflect the impact of the aerial layer on communication. For example, a high normal operation ratio of drones indicates that the overall reliability of the aerial layer equipment is good, but if the remaining flight time is too short, the risk of communication interruption will increase; abnormal frequency of changes in the altitude of the high-altitude communication platform will also affect signal coverage and transmission quality. Combining these factors to obtain the aerial layer communication status signal can more accurately assess the potential impact of the aerial layer on communication networking, detect possible communication problems in advance, and warn of communication risks in advance.

[0048] The aerial layer communication status signal of the area to be analyzed, the specific analysis process is as follows:

[0049]

[0050] Where α is the communication status signal of the aerial layer in the area to be analyzed, wrz is the normal operation ratio of the aerial layer UAV, syf is the remaining flight time of the aerial layer UAV, zk is the frequency of change of the altitude of the aerial layer high-altitude communication platform, σ 1 is the compensation factor of the set wrz, σ 2 is the compensation factor of the set syf, σ 3 is the compensation factor of the set zk.

[0051] The three key factors, namely the normal operation ratio of aerial layer UAVs, the remaining flight time, and the frequency of changes in the altitude of the high-altitude communication platform, affect the communication capability of the aerial layer from different angles. The aerial layer communication status signal is calculated, which can comprehensively evaluate the communication status of the aerial layer. The normal operation ratio of UAVs is directly related to the number of nodes that can normally participate in the communication task; the remaining flight time determines how long the UAV can continue to provide communication support in the current task; and the frequency of changes in the altitude of the high-altitude communication platform affects the stability of signal coverage. Comprehensive consideration of these factors can avoid the one-sidedness of relying on a single factor to judge the communication status of the aerial layer, and can provide early warning of possible problems in the aerial layer communication system.

[0052] The ground layer status of the area to be analyzed is analyzed, and combined with the communication status signal of the aerial layer in the area to be analyzed, the air-ground integrated communication factor of the area to be analyzed is obtained. Combined with the air-ground integrated communication threshold of the area to be analyzed, it is determined whether the emergency response plan needs to be activated.

[0053] The specific analysis process is as follows: obtaining the ground layer status data of the area to be analyzed, which specifically includes the normal operation ratio of ground layer emergency communication vehicles, the average transmission power deviation rate of ground layer macro base stations, and the transmission capacity of ground layer communication cables; based on the obtained ground layer status data of the area to be analyzed, combined with the aerial layer communication status signal of the area to be analyzed, the air-ground integrated communication factor of the area to be analyzed is obtained, and the air-ground integrated communication factor of the area to be analyzed is used as the analysis basis for determining whether it is necessary to activate the emergency response plan.

[0054] The normal operation ratio of ground-layer emergency communication vehicles refers to the ratio of the number of emergency communication vehicles in normal operation to the total number of emergency communication vehicles in the area to be analyzed. The average transmission power deviation rate of ground-layer macro base stations refers to the degree of deviation between the actual average transmission power of all macro base stations and this standard reference value, usually expressed as a percentage. The transmission capacity of ground-layer communication cables refers to the amount of data that can be transmitted by ground-layer communication cables (mainly optical fiber cables and some copper cables used for power communication) per unit time, usually measured in bits per second (bps) or its multiples (such as Mbps, Gbps).

[0055] By obtaining various status data such as the normal operation ratio of emergency communication vehicles on the ground layer, the average transmission power deviation rate of macro base stations on the ground layer, and the transmission capacity of communication cables on the ground layer, and combining them with the communication status signal of the air layer, the overall status of the air-ground integrated communication system can be comprehensively considered. These data reflect the performance of the communication system from different angles. The normal operation ratio of emergency communication vehicles reflects the emergency communication guarantee capability of the ground layer in an emergency; the average transmission power deviation rate of macro base stations can reflect whether the base station is working normally and whether the signal coverage is affected; the transmission capacity of communication cables is related to the carrying capacity of ground wired communications. The air-ground integrated communication factor obtained by combining these factors can more accurately evaluate the health status of the entire communication system and provide a more comprehensive and accurate judgment basis for the launch of emergency response plans.

[0056] The air-ground integrated communication factors of the area to be analyzed, the specific analysis process is as follows:

[0057]

[0058] Where β is the air-ground integrated communication factor of the area to be analyzed, czc is the normal operation ratio of the emergency communication vehicle on the ground layer, fpl is the average transmission power deviation rate of the macro base station on the ground layer, lcs is the transmission capacity of the communication cable on the ground layer, τ 1 is the compensation factor of the set czc, τ 2 is the compensation factor of the set fpl, τ 3 is the compensation factor of the set lcs.

[0059] By combining the normal operation ratio of ground-layer emergency communication vehicles, the average transmission power deviation rate of ground-layer macro base stations, the transmission capacity of ground-layer communication cables, and the communication status of the aerial layer in the area to be analyzed, the air-ground integrated communication factor of the area to be analyzed can be calculated, which can comprehensively consider all key aspects of the ground-layer and aerial-layer communication systems. These factors reflect the availability, signal coverage, and data transmission capacity of ground-layer and aerial-layer communication resources from different angles.

[0060] The air-ground integrated communication factor of the area to be analyzed is compared with the air-ground integrated communication threshold of the area to be analyzed; if the air-ground integrated communication factor of the area to be analyzed is not lower than the air-ground integrated communication threshold of the area to be analyzed, the area to be analyzed corresponding to the air-ground integrated communication factor of the area to be analyzed does not need to activate the emergency response plan; if the air-ground integrated communication factor of the area to be analyzed is lower than the air-ground integrated communication threshold of the area to be analyzed, the area to be analyzed corresponding to the air-ground integrated communication factor of the area to be analyzed needs to activate the emergency response plan.

[0061] By comparing the air-ground integrated communication factor and threshold of the area to be analyzed, it is possible to accurately determine whether the emergency response plan needs to be initiated. This approach avoids overreaction or underreaction. For example, in some minor communication fluctuation scenarios, such as short-term signal interference or minor failures of individual equipment, if the communication factor is still not lower than the threshold, it means that the communication system as a whole can still operate normally, and there is no need to initiate an emergency response, thus avoiding unnecessary waste of resources and interference of emergency operations with normal communication services.

[0062] When problems occur in the communication system, timely activation of the emergency response plan can ensure the continuity of communication services. Once the communication factor is below the threshold, the emergency response plan is immediately activated, and communication functions are quickly restored by enabling backup equipment. For example, when natural disasters cause damage to some ground base stations and interruption of air communication links, emergency response is initiated in a timely manner, and backup emergency communication vehicles are dispatched, damaged links are repaired, and drone flight paths are replanned to ensure that communication services for power grid operations are not interrupted and to maintain safe and stable operation of the power grid.

[0063] The transmission status of the communication link in the area to be analyzed is analyzed, and combined with the transmission threshold of the communication link in the area to be analyzed, it is determined whether the backup communication link needs to be started.

[0064] like Figure 3 As shown, the specific analysis process is: obtaining the communication link transmission status data of the area to be analyzed, the communication link transmission status data of the area to be analyzed specifically includes the average signal strength of the communication link, the average transmission delay of the communication link, and the interruption frequency of the communication link; based on the obtained communication link transmission status data of the area to be analyzed, a comprehensive analysis is performed to obtain the communication link transmission factor of the area to be analyzed, and the communication link transmission factor of the area to be analyzed is used as an analysis basis for judging whether it is necessary to start the backup communication link; comparing the communication link transmission factor of the area to be analyzed with the communication link transmission threshold of the area to be analyzed; if the communication link transmission factor of the area to be analyzed is not lower than the communication link transmission threshold of the area to be analyzed, then the area to be analyzed corresponding to the communication link transmission factor of the area to be analyzed does not need to start the backup communication link; if the communication link transmission factor of the area to be analyzed is lower than the communication link transmission threshold of the area to be analyzed, then the area to be analyzed corresponding to the communication link transmission factor of the area to be analyzed needs to start the backup communication link.

[0065] The average signal strength of a communication link refers to the average value of the signal power on all communication links (links between the air layer and the ground layer, between base stations, between devices and base stations, etc.). It is usually measured in decibel milliwatts (dBm). The average transmission delay of a communication link refers to the average time delay experienced by data from the transmitter to the receiver of the communication link. It includes the time it takes for the signal to propagate in the transmission medium, the time it takes for the device to process the data (such as encoding, decoding, caching, etc.), and the waiting time in queues. It is usually measured in milliseconds (ms) or microseconds (μs). The frequency of communication link interruption refers to the number of times a communication link is interrupted within a certain time range. For example, in one day, if a communication link between a drone and a ground base station fails to transmit data normally three times, then the interruption frequency of this communication link in that day is 3 times / day.

[0066] By obtaining data such as the average signal strength, average transmission delay, and interruption frequency of the communication link to comprehensively analyze the communication link transmission factor, the health of the communication link can be comprehensively and quantitatively evaluated. For example, when the average signal strength gradually weakens, the transmission delay increases, or the interruption frequency increases, the communication link transmission factor will decrease accordingly, and the risk of possible failure of the link will be warned in advance. This allows the communication system to take measures before the link is completely interrupted, avoiding problems such as power grid data loss or power grid operation interruption caused by communication interruption.

[0067] The judgment mechanism based on the communication link transmission factor can enhance the pertinence of emergency response. When a problem occurs in a communication link, instead of blindly starting all backup resources, a suitable backup communication link is selected based on the specific situation of the link transmission factor. For example, if the communication link transmission factor is only slightly lower than the threshold, and the main problem is a slightly longer transmission delay, a backup link with better delay optimization can be started; if the signal strength is seriously insufficient and the interruption frequency is high, a backup link with wide coverage and high signal strength is selected to improve the accuracy and effectiveness of the emergency response.

[0068] The communication link transmission factor of the area to be analyzed, the specific analysis process is:

[0069]

[0070] In the formula, γ is the transmission factor of the communication link in the area to be analyzed, qd is the average signal strength of the communication link, csy is the average transmission delay of the communication link, zdp is the interruption frequency of the communication link, and ε 1 is the compensation factor of the set qd, ε 2 is the compensation factor of the set csy, ε 3 is the compensation factor for the set zdp.

[0071] The communication link transmission factor combines the three key factors of average signal strength, average transmission delay and interruption frequency, and can comprehensively reflect the performance of the communication link. These three factors affect the communication link from different aspects, and considering one of them alone cannot fully evaluate the health of the link. Calculating them together to get the transmission factor can more accurately measure the quality of the communication link in actual operation. The communication link transmission factor is used as a basis for determining whether to start a backup communication link, and can make decisions more scientifically and objectively. When the transmission factor is lower than a certain set threshold, it can be clearly determined that there is a serious problem with the current communication link, and the backup link needs to be started to ensure the continuity of communication.
