Description

Technical Field

[0001] This invention belongs to the field of smart distribution network communication technology, specifically relating to a distribution network converged communication system adapted for power private networks. Background Technology

[0002] In the current construction of smart grids, the distribution network, as a key link in power supply, is crucial for ensuring reliable power supply and improving energy efficiency. Communication transmission technology plays a central role in smart distribution network construction, enabling interconnection between devices, remote real-time monitoring, and precise automated control, thus forming the foundation for the efficient operation of the entire smart distribution network.

[0003] However, the actual geographical conditions of the power grid's service area are extremely complex, with mountains and hills accounting for over 67% of the area. This complex terrain presents numerous obstacles to communication. At the same time, natural disasters occur frequently, such as typhoons, torrential rains, and mudslides, causing severe damage to communication infrastructure. Against this backdrop, traditional communication technologies relying on dedicated power grids, such as 4G / 5G public networks and microwave communication, have revealed a series of problems when dealing with these complex terrains and disaster situations.

[0004] First, in mountainous areas, wireless communication coverage is severely inadequate, and signal stability is extremely poor. Traditional power wireless private networks are affected by mountain obstruction and multipath effects, resulting in numerous signal coverage blind spots and severe signal attenuation. The sparse deployment of base stations in remote mountainous areas often leaves distribution terminals without network or with weak signals, preventing the timely transmission of critical data and severely impacting the real-time perception and decision-making of distribution network automation systems. Second, communication links are highly susceptible to interruption during disasters, leading to significant delays in emergency response. Existing systems rely on single communication links and lack multi-channel redundancy mechanisms. Communication interruptions after a disaster prevent timely reporting of fault information, hindering emergency repairs. Third, in weak network environments, data transmission efficiency is low, while energy consumption and costs are high. Dispersed distribution equipment in mountainous areas necessitates frequent data retransmissions under weak signal conditions, significantly increasing terminal power consumption and shortening battery life. Furthermore, traditional compression algorithms are poorly adapted to multi-source heterogeneous data, and encryption protocols incur high computational overhead in weak networks. Finally, existing technologies lack the ability to adapt to dynamic environmental changes. The micro-meteorological environment in mountainous areas is complex and changeable, making it difficult for traditional communication systems to dynamically adjust transmission parameters. This results in low channel resource utilization, easy loss of critical data, and affects the accuracy of disaster early warning. Summary of the Invention

[0005] In view of this, the present invention provides a distribution network converged communication system adapted to power private networks, aiming to overcome the above-mentioned shortcomings of existing traditional power private network communication technologies in complex mountainous environments.

[0006] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0014] Furthermore, the edge processing device is also configured to monitor the tilt status of the pole:

[0015] If the tilt angle of the tower is detected to reach the set angle, monitoring data representing the tilt information of the tower is generated, and the tilt information is marked as the highest priority.

[0016] If the signal strength of the 5G communication module is higher than the set signal strength threshold, the tilt information marked with the highest priority will be sent to the remote monitoring center through the 5G communication module.

[0017] If the signal strength of the 5G communication module is lower than or equal to the set signal strength threshold, the tilt information marked with the highest priority will be used as key data and sent to the remote monitoring center through the Beidou short message communication module.

[0023] The charging placement cavity is used to park the inspection drone and is electrically connected to the edge processing device to charge the inspection drone.

[0024] The location receiver is mounted on the communication plug-in mechanism and electrically connected to the edge processing device. It is used to receive location information sent by the location transmitter on the inspection drone.

[0025] The communication plug-in mechanism is installed on the mobile mechanism and is used to plug into the charging and communication port of the inspection drone under the drive of the mobile mechanism, so as to realize the wired connection between the inspection drone and the edge processing equipment.

[0026] The mobile mechanism is electrically connected to the edge processing device, which is configured to control the mobile mechanism to move the communication plug-in mechanism to the charging communication port and complete the plug-in based on the location information obtained by the location receiver.

[0027] Furthermore, the charging communication port includes independent charging sub-ports and communication sub-ports;

[0028] The communication connector is equipped with a retractable plug, which includes a charging sub-connector adapted to the charging sub-port and a communication sub-connector adapted to the communication sub-port.

[0029] The edge processing device is configured to: if it detects that the battery level of the inspection drone is lower than a set threshold, control the charging sub-connector to supply power to the inspection drone, and at the same time receive the inspection data sent by the inspection drone through the communication sub-connector.

[0030] Furthermore, it also includes: a LoRa communication module;

[0031] The LoRa communication module is located inside the edge processing device and is electrically connected to the edge processing device.

[0032] The edge processing device is configured to: if it detects that the inspection drone has entered the radio frequency transmission range of the LoRa communication module, it attempts to establish a LoRa communication connection with the inspection drone; if the connection is successful, it receives the inspection data sent by the inspection drone through the LoRa communication module; if the connection fails, it controls the drone charging connection device to receive the inspection data sent by the inspection drone through a wired connection.

[0033] Furthermore, the edge processing device is also configured as follows:

[0034] During the transmission of inspection data through the LoRa communication module, the current frequency usage, current signal-to-noise ratio, current signal strength, and current network load of the neighboring wireless communication network are obtained. The various information of the neighboring wireless communication network are then input into the model used to determine the transmission channel to obtain the spreading factor, bandwidth, coding rate, operating frequency, data transmission frequency, and current frequency band channel.

[0035] The data transmission configuration of the LoRa communication module is adjusted according to the obtained spreading factor, bandwidth, coding rate, operating frequency, and data transmission frequency, and the current frequency band channel is used as the transmission channel to realize the dynamic adjustment of the LoRa communication module.

[0036] Furthermore, mobile mechanisms include:

[0043] The edge processing device is configured to control the coordinated movement of the horizontal motion platform, the vertical motion platform, and the rotating platform, thereby driving the communication plug-in mechanism to connect to the charging and communication port of the inspection drone.

[0044] Furthermore, the edge processing device is also configured as follows:

[0045] Perform fault identification and processing on the received inspection data;

[0046] If a fault is identified, the fault identification result is marked as the highest priority;

[0047] If the signal strength of the 5G communication module is higher than the set signal strength threshold, the fault identification result will be sent through the 5G communication module.

[0048] If the signal strength of the 5G communication module is lower than or equal to the set signal strength threshold, the fault identification result will be used as key data and sent to the remote monitoring center via the Beidou short message communication module. At the same time, the fault identification result and the original inspection data will be stored locally. After the signal strength of the 5G communication module is restored, the original inspection data will be sent to the remote monitoring center.

[0049] In summary, this invention provides a distribution network converged communication system adapted for power private networks, including an edge processing device, a 5G communication module, a switching device, a BeiDou short message communication module, and a BeiDou short message passive antenna. The edge processing device is installed at the monitored power equipment. Both the 5G communication module and the BeiDou short message communication module are located within the edge processing device. After the 5G communication module and the BeiDou short message communication module are electrically connected to the switching device and the BeiDou short message passive antenna respectively, a wireless communication connection is established with the remote monitoring center through the switching device and the BeiDou short message passive antenna. The edge processing device is configured to acquire monitoring data of the power equipment and / or inspection data of the transmission lines, and monitor the signal strength of the 5G communication module. If the signal strength of the 5G communication module is higher than a set signal strength threshold, the monitoring data and / or inspection data are sent to the remote monitoring center through the 5G communication module. If the signal strength of the 5G communication module is not higher than the set signal strength threshold, the key data of the monitoring data and / or inspection data are extracted and sent to the remote monitoring center through the BeiDou short message communication module. This invention can switch transmission modules according to 5G signal strength and extract key data when the signal is weak. It uses BeiDou short message transmission, which can effectively improve the problems of insufficient wireless communication coverage and poor signal stability in mountainous areas. It can improve data transmission efficiency in weak network environments and reduce energy consumption and costs. This overcomes the shortcomings of existing traditional power grid communication technologies in complex mountainous environments, ensures the accuracy of real-time perception, decision-making and disaster early warning of distribution network automation systems, and helps to carry out emergency repairs efficiently.

[0060] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0061] Please see Figure 1 This embodiment provides a distribution network converged communication system adapted for power private networks, including:

[0062] Edge processing equipment, 5G communication modules, switching equipment, BeiDou short message communication modules, and BeiDou short message passive antennas;

[0063] Edge processing devices are installed within the monitoring equipment. These edge processing devices are localized intelligent devices deployed near the monitored power equipment (such as power poles, substations, etc.), and have data acquisition, analysis, storage, and communication control functions.

[0064] In addition to the main body of the edge processing device, a 5G communication module and a Beidou short message communication module are also provided inside the edge processing device. Among them, the 5G communication module is a communication component integrated into the edge processing device, which supports data transmission through the 5G network and has the characteristics of large bandwidth (able to transmit a large amount of data) and low latency (strong real-time performance), and is suitable for monitoring data or patrol data that need to be efficiently transmitted in the power system. The Beidou short message communication module is a communication component based on the Beidou satellite navigation system, integrated into the edge processing device, and can send data in the form of short messages through satellites in scenarios without a ground network (such as blind areas covered by 5G signals), and is suitable for emergency communication and data transmission in remote areas.

[0065] The 5G communication module is electrically connected to the remote monitoring center through a switching device, and the Beidou short message communication module is communicatively connected to the remote monitoring center through a Beidou short message passive antenna. Among them, the switching device is a network device that cooperates with the 5G communication module, responsible for data forwarding, routing management, and link maintenance, and is used to achieve a stable connection between the 5G communication module and the remote monitoring center. The Beidou short message passive antenna is an antenna配套with the Beidou short message communication module, which does not require additional power supply and is used to receive and transmit Beidou satellite signals. The Beidou short message passive antenna is embedded and installed on the outside of the edge processing device in a detachable and retractable manner.

[0066] The edge processing device is configured to obtain the monitoring data of power equipment and / or the patrol data of transmission lines, and monitor the signal strength of the 5G communication module; if the signal strength of the 5G communication module is higher than the set signal strength threshold, the monitoring data and / or patrol data will be sent to the remote monitoring center through the 5G communication module, and if the signal strength of the 5G communication module is not higher than the set signal strength threshold, the key data of the monitoring data and / or patrol data will be extracted and sent to the remote monitoring center through the Beidou short message communication module.

[0067] It should be noted that the monitoring data is the operation state data of power equipment directly collected by the edge processing device (such as the inclination angle of the tower, equipment temperature, voltage and current, etc.). The patrol data is the state data of transmission lines obtained through methods such as drones and manual patrols (such as line damage images, foreign object intrusion videos, etc.). The key data is the core information extracted from the monitoring data or patrol data when the 5G signal is poor (such as fault warnings, emergency status indicators, etc.), with the highest priority and needs to be preferentially transmitted through the Beidou short message.

[0068] This embodiment provides a distribution network converged communication system adapted for power private networks. The system deploys edge processing devices integrating 5G and BeiDou short message communication modules at the monitored power equipment to acquire real-time monitoring data of the power equipment and transmission line inspection data. The edge processing device dynamically monitors the 5G signal strength. When the signal is strong, it transmits complete data to the remote monitoring center via the 5G communication module and switching equipment. When the signal is weak, it extracts key data and transmits it to the remote monitoring center via satellite through the BeiDou short message communication module and passive antenna, achieving adaptive switching of communication methods based on signal quality. This system integrates 5G and BeiDou short message dual-mode communication, utilizing the high bandwidth and low latency of 5G to transmit full data, and leveraging the wide coverage advantage of BeiDou short message communication (which does not rely on terrestrial networks) to ensure emergency transmission of critical data. The edge processing device locally implements data priority extraction and intelligent switching, overcoming the coverage limitations of single communication methods in complex power scenarios, optimizing communication resource utilization efficiency, and improving the reliability and emergency response capabilities of power private network data transmission.

[0069] In some embodiments, the monitored power equipment is a pole or tower;

[0070] Edge processing devices are installed independently on the pole; or

[0071] The edge processing device is integrated into the electronic equipment already installed on the pole, which is a monitoring device used to monitor the status of the pole.

[0072] In this embodiment, if the edge processing device is integrated into the existing monitoring equipment on the pole, the installation carrier of the monitoring equipment can be reused directly, reducing the additional deployment cost of the pole. If it is installed independently, the installation location can be flexibly selected according to the monitoring needs of the pole, adapting to the structural and environmental characteristics of different poles.

[0073] In some embodiments, the edge processing device is also configured to monitor the tilt state of the tower:

[0074] If the tilt angle of the tower is detected to reach the set angle, monitoring data representing the tilt information of the tower is generated, and the tilt information is marked as the highest priority.

[0075] If the signal strength of the 5G communication module is higher than the set signal strength threshold, the tilt information marked with the highest priority will be sent to the remote monitoring center through the 5G communication module.

[0076] If the signal strength of the 5G communication module is lower than or equal to the set signal strength threshold, the tilt information marked with the highest priority will be used as key data and sent to the remote monitoring center through the Beidou short message communication module.

[0077] In this embodiment, the edge processing device can monitor the tower tilt angle in real time. When the tilt angle reaches a set value, a wake-up warning mechanism is triggered, generating and storing the tower tilt information. Subsequently, the availability of the dedicated power grid 5G channel is determined by monitoring the signal strength of the 5G communication module: if the signal strength is sufficient, the tilt information is marked as the highest priority and sent to the remote monitoring center via 5G; if the signal is insufficient, the Beidou short message communication module is activated to transmit the tilt information (critical data) to the remote monitoring center via satellite, ensuring uninterrupted emergency feedback for tower anomalies. Furthermore, when the tower tilt angle reaches a set angle, a wake-up warning mechanism must be triggered and the tilt information stored.

[0078] In power distribution networks, drones are frequently used to inspect power poles and lines. Current technology typically involves mounting an edge computing box on the bottom of the drone. However, this largely relies on a 5G network connection to a remote monitoring center. Without a 5G signal, the edge computing box cannot send inspection results to the remote monitoring center. Therefore, in some implementations, such as... Figure 2 As shown, the converged communication system also includes: a drone charging connection device;

[0079] The drone charging connection device is installed in the monitored power equipment and is located on the side close to the edge processing device;

[0080] The drone charging connection device is electrically connected to the edge processing equipment, and is used for parking and charging of inspection drones used for inspecting power transmission lines, and to realize inspection data transmission between the inspection drones and the edge processing equipment.

[0081] In this embodiment, the drone charging connection device is electrically connected to the edge processing device. Its function is twofold: firstly, to provide parking space and charging services for the inspection drones returning after inspecting power transmission lines; and secondly, to realize the transmission of inspection data between the inspection drones and the edge processing device. Even in scenarios without 5G signals, the device can effectively transmit inspection data, ensuring the continuity of inspection work and the integrity of the data.

[0082] In some embodiments, the drone charging connection device includes:

[0083] Charging placement cavity, moving mechanism, communication plug-in mechanism, and position receiver;

[0084] The charging placement cavity is used for parking the inspection drone and is electrically connected to the edge processing device to charge the inspection drone. The charging placement cavity is a semi-open cavity with an opening on the side, and is divided into a charging cavity and a receiving cavity. The receiving cavity has an open area for the movement of the moving mechanism, and is located below the charging cavity with the open area close to the charging cavity. The edge processing device is integrated into the receiving cavity.

[0085] The location receiver is mounted on the communication plug-in mechanism and electrically connected to the edge processing device. It is used to receive location information sent by the location transmitter on the inspection drone.

[0086] The communication plug-in mechanism is installed on the mobile mechanism and is used to plug into the charging and communication port of the inspection drone under the drive of the mobile mechanism, so as to realize the wired connection between the inspection drone and the edge processing equipment.

[0087] The mobile mechanism is electrically connected to the edge processing device, which is configured to control the mobile mechanism to move the communication plug-in mechanism to the charging communication port and complete the plug-in based on the location information obtained by the location receiver.

[0088] In this embodiment, the charging placement cavity is used for parking the inspection drone. Its bottom has a parking area for the drone and a moving area for the mobile mechanism. The moving area is located between the parking areas and is electrically connected to the edge processing device. During drone parking, the edge processing device can directly replenish the drone's power. A location receiver is mounted on the communication plug-in mechanism and is also electrically connected to the edge processing device. Within a preset range of the location transmitter, it can receive and acquire specific location information sent by the location transmitter on the inspection drone. Its function is to receive the location information sent by the location transmitter on the inspection drone for subsequent precise docking. The communication plug-in mechanism is installed on the mobile mechanism and can move flexibly under the movement of the mobile mechanism, ultimately connecting to the charging communication port of the inspection drone, thus achieving a wired connection between the inspection drone and the edge processing device. All the above-mentioned electrical connections are wired connections. Wired connections ensure the stability and security of data transmission and avoid interference problems that may occur with wireless transmission in complex power environments. The mobile mechanism is also electrically connected to the edge processing device.

[0089] The edge processing device is configured to precisely control the movement trajectory of the mobile mechanism based on the location information of the inspection drone obtained from the location receiver, driving the communication plug-in mechanism to move accurately to the charging communication port and complete the plug-in. After the plug-in is completed and the wired connection is successfully established, the edge processing device sends a command to the edge computing box on the inspection drone side to retrieve inspection data, and the inspection drone then sends the stored inspection data to the edge processing device.

[0090] In some specific implementations, when the drone charging connection device determines that the inspection drone is parked in the charging placement cavity, the inspection drone activates its position transmitter. The position receiver receives the position information from the position transmitter and sends the acquired position information to the edge processing device. Based on the acquired position information, the edge processing device controls the moving mechanism to move the communication plug-in mechanism to below the charging communication port of the inspection drone, and controls the communication plug-in mechanism to insert into the charging communication port and connect with the edge processing device via wire. After confirming that the wired connection is successful, it sends a data acquisition command to the edge computing box on the inspection drone side, indicating that it wants to acquire inspection data. Based on the acquisition command, the inspection drone sends the stored inspection data to the edge processing device so that the edge processing device can perform fault identification processing on the inspection data and analyze the fault identification processing results. If the fault identification result is determined to be faulty, the fault identification result is marked as the highest priority and sent to the remote monitoring center through the Beidou short message communication module. If the 5G signal strength of the current network reaches the signal strength threshold during the parking of the inspection drone, the inspection data of the inspection drone will be sent to the remote monitoring center through the 5G dedicated channel so that the remote monitoring center can further analyze the inspection data.

[0091] In other specific implementations, when the inspection drone detects that the 5G signal strength of the current network has reached the signal strength threshold during the inspection process, the inspection drone processes the captured data images through the edge computing box and sends the fault identification results after fault monitoring to the remote monitoring center through a dedicated channel.

[0092] In some embodiments, the charging communication port includes a charging sub-port and a communication sub-port that are independent of each other;

[0093] The communication connector is equipped with a retractable plug, which includes a charging sub-connector adapted to the charging sub-port and a communication sub-connector adapted to the communication sub-port.

[0094] The edge processing device is configured to: if it detects that the battery level of the inspection drone is lower than a set threshold, control the charging sub-connector to supply power to the inspection drone, and at the same time receive the inspection data sent by the inspection drone through the communication sub-connector.

[0095] In this embodiment, to further optimize the coordination efficiency of charging and data transmission in the drone charging connection device, the charging communication port of the inspection drone is equipped with independent charging sub-ports and communication sub-ports. This separate design allows for the independent operation and synchronous implementation of charging and data transmission functions. Correspondingly, the retractable plug of the communication connector also has charging sub-connectors and communication sub-connectors, which can be plugged into the charging sub-port and communication sub-port of the charging communication port, respectively. During actual operation, the edge processing device is configured to monitor the battery status of the inspection drone in real time. If the battery level is detected to be below a set threshold, a collaborative control process is initiated: on the one hand, the charging sub-connector of the retractable plug is connected to the charging sub-port of the charging communication port to supply power to the inspection drone; on the other hand, while charging, the inspection data sent by the inspection drone is simultaneously received through the connection of the communication sub-connector of the retractable plug to the communication sub-port of the charging communication port, eliminating the need to wait for charging to complete before data transmission. This greatly improves the transmission efficiency of inspection data and further enhances the reliable transmission of inspection data in scenarios with no or poor 5G signal. In addition, the edge computing device is networked with the drone, enabling it to acquire image information captured by the drone in real time and store the image information locally. In practical applications, if it is determined that the drone and the edge computing device are connected via a 5G communication link, the device acquires image data captured by the drone in real time or image data stored locally. If it is determined that the drone and the edge monitoring device are connected via a BeiDou link, the device acquires warning information indicating faults sent by the edge computing device deployed on the bottom of the drone in real time, and sends the received warning information to the remote monitoring system in the form of BeiDou short messages.

[0096] In some embodiments, it further includes: a LoRa communication module;

[0097] The LoRa communication module is located inside the edge processing device and is electrically connected to the edge processing device.

[0098] The edge processing device is configured to: if it detects that the inspection drone has entered the radio frequency transmission range of the LoRa communication module, it attempts to establish a LoRa communication connection with the inspection drone; if the connection is successful, it receives the inspection data sent by the inspection drone through the LoRa communication module; if the connection fails, it controls the drone charging connection device to receive the inspection data sent by the inspection drone through a wired connection.

[0099] In this embodiment, a LoRa communication module is provided to further enrich the transmission path of inspection data and improve the flexibility and reliability of data transmission. During actual operation, the edge processing device is configured to monitor the location status of the inspection drone in real time. When the inspection drone enters the preset radio frequency transmission range of the LoRa communication module, it first attempts to establish a LoRa communication connection with the drone. This leverages the low power consumption and long-distance transmission advantages of LoRa communication technology to achieve wireless transmission of inspection data without requiring the drone to dock for charging, thus improving data transmission efficiency. If the LoRa communication connection fails due to signal interference, equipment failure, or other reasons (i.e., when the inspection drone determines that the LoRa communication module is not responding), the edge processing device switches the data transmission mode and controls the previously configured drone charging connection device to initiate a wired connection process. This involves connecting the device to the drone's charging communication port via a communication plug-in mechanism to receive the inspection data sent by the drone via a wired connection.

[0100] In some embodiments, the edge processing device is further configured to:

[0101] During the transmission of inspection data through the LoRa communication module, the current frequency usage, current signal-to-noise ratio, current signal strength, and current network load of the neighboring wireless communication network are obtained. The various information of the neighboring wireless communication network are then input into the model used to determine the transmission channel to obtain the spreading factor, bandwidth, coding rate, operating frequency, data transmission frequency, and current frequency band channel.

[0102] The data transmission configuration of the LoRa communication module is adjusted according to the obtained spreading factor, bandwidth, coding rate, operating frequency, and data transmission frequency, and the current frequency band channel is used as the transmission channel, thereby realizing the dynamic adjustment of the LoRa communication module.

[0103] It should be noted that the nearby wireless communication network refers to various wireless communication networks that are geographically close to the distribution network communication network where the LoRa communication module is located and may cause signal interaction or interference. The model used to determine the transmission channel can be a rule-driven computational model or a machine learning model. By receiving data from the nearby wireless communication network collected by the edge processing device, and combining the data parsing and logical operations with the requirements of LoRa communication in the power distribution network inspection scenario, the transmission channel with minimal communication interference and optimal transmission efficiency, along with the corresponding parameter settings, can be obtained.

[0104] In this embodiment, to further optimize communication efficiency, avoid interference, and ensure communication quality under harsh conditions, the edge processing device is also configured to dynamically adjust the transmission parameters of the LoRa communication module. First, the edge processing device actively acquires key information about the neighboring wireless communication network, specifically including current frequency usage, current signal-to-noise ratio, current signal strength, and current network load. Next, the edge processing device inputs the collected information from the neighboring network into a pre-set model for determining the transmission channel. Through model analysis and calculation, it obtains the spreading factor, bandwidth, coding rate, operating frequency, data transmission frequency, and current frequency band channel suitable for the current environment, ensuring that all parameters match the actual communication scenario. Subsequently, the edge processing device adjusts the data transmission configuration of the LoRa communication module according to the model output, and uses the determined current frequency band channel as the transmission channel for the inspection data. During the dynamic adjustment process, communication efficiency is improved by optimizing the spreading factor, bandwidth, and coding rate. Simultaneously, the frequency band with the least interference and highest signal-to-noise ratio is selected by referencing the frequency usage of neighboring networks. The operating frequency and data transmission frequency can be flexibly adjusted to avoid sudden interference. If interference is detected between the current frequency usage of a neighboring network and the local network, the process returns to the step of obtaining neighboring network information and recalculating and adjusting parameters. This embodiment fully considers the impact of neighboring networks, effectively avoiding co-channel interference. Even under adverse communication conditions, it can maintain minimum communication quality through dynamic adjustment, ensuring the stability and reliability of inspection data transmission.

[0106] Horizontal motion platform, vertical motion platform, and rotary platform;

[0107] The horizontal motion platform is installed at the monitored power equipment;

[0112] The edge processing device is configured to control the coordinated movement of the horizontal motion platform, the vertical motion platform, and the rotating platform, thereby driving the communication plug-in mechanism to connect to the charging and communication port of the inspection drone.

[0113] In this embodiment, the moving mechanism consists of a horizontal motion platform, a vertical motion platform, and a rotating platform. The horizontal motion platform, serving as the basic support, is directly installed at the monitored power equipment, providing a stable mounting base for the entire moving mechanism. The vertical motion platform is installed on top of the horizontal motion platform, enabling vertical position adjustment. The rotating platform is installed on top of the vertical motion platform, driving the communication plug-in mechanism to rotate at an angle. The communication plug-in mechanism is ultimately fixed to the rotating platform, and all three move together in three dimensions. The edge processing device controls the coordinated movement of the three platforms based on the position information of the inspection drone's charging communication port obtained by the position receiver. The horizontal motion platform adjusts the left-right and front-back positions of the communication plug-in mechanism on the horizontal plane, the vertical motion platform adjusts its vertical height, and the rotating platform corrects its docking angle, ultimately allowing the communication plug-in mechanism to align and dock with the inspection drone's charging communication port in three-dimensional space.

[0114] For example, Figure 3The structural design of a drone charging connection device is shown. The device includes a horizontal motion platform 1, a vertical motion platform 2, a rotating platform 3, and a communication connection mechanism 4. The horizontal motion platform 1 is housed within a receiving cavity 5. The vertical motion platform 2 is mounted on the horizontal motion platform 1 and can move horizontally under the influence of the horizontal motion platform 1. The rotating platform 3 is mounted on the vertical motion platform 2 and can move vertically under the influence of the vertical motion platform 2. The communication connection mechanism 4 is mounted on the rotating platform 3. The horizontal motion platform 1, vertical motion platform 2, and rotating platform 3 are all electrically connected to an edge processing device to drive the communication connection mechanism 4 to achieve horizontal, vertical, and rotational movements. Above the communication connection mechanism 4 is the charging cavity 6. The horizontal motion platform 1 includes a horizontal motor 11, a horizontal lead screw 12, a horizontal balance lead screw 13, two horizontal bearings, and a horizontal threaded plate 14 with two threaded holes. The output end of the horizontal motor 11 is equipped with a horizontal lead screw 12. The vertical motion platform 2 includes a vertical motor, a vertical lead screw 21, a vertical balance lead screw 22, two vertical bearings, and a vertical threaded plate 23 with two threaded holes. The rotating platform 3 includes a rotating motor 31 and a rotating table 32. The communication plug-in mechanism 4 includes a longitudinal motor 41, a longitudinal lead screw 42, a threaded tube 43, and a plug (including a communication plug 44 and a charging plug 45). The horizontal lead screw 12 and the horizontal balance lead screw 13 are fitted into the corresponding threaded holes of the horizontal threaded plate 14, and the output ends of both the horizontal lead screw 12 and the horizontal balance lead screw 13 are connected to water. A horizontal bearing is mounted on the receiving cavity 5; a vertical motor is mounted on a horizontal threaded plate 14, and a vertical lead screw 21 is mounted on the output end of the vertical motor. The vertical lead screw 21 and the vertical balance lead screw 22 are fitted into the corresponding threaded holes of the vertical threaded plate 23, and the output ends of the vertical lead screw 21 and the vertical balance lead screw 22 are both connected to the vertical bearing. The vertical bearing is mounted on the horizontal threaded plate 14 or the receiving cavity 5; a rotary motor 31 is mounted at the middle position of the vertical threaded plate 23, and one end face of the rotary table 32 is mounted on the output end of the rotary motor 31.

A longitudinal lead screw 42 is mounted on the output end of the longitudinal motor 41, and a threaded tube 43 is fitted onto the longitudinal lead screw 42. A charging plug 44 and a communication plug 45 are mounted on the end of the threaded tube 43.

[0115] In some embodiments, the edge processing device is further configured to:

[0116] Perform fault identification and processing on the received inspection data;

[0117] If a fault is identified, the fault identification result is marked as the highest priority;

[0118] If the signal strength of the 5G communication module is higher than the set signal strength threshold, the fault identification result will be sent through the 5G communication module.

[0119] If the signal strength of the 5G communication module is lower than or equal to the set signal strength threshold, the fault identification result will be used as key data and sent to the remote monitoring center via the Beidou short message communication module. At the same time, the fault identification result and the original inspection data will be stored locally. After the signal strength of the 5G communication module is restored, the original inspection data will be sent to the remote monitoring center.

[0120] In this embodiment, the edge processing device first performs fault identification processing on the received inspection data (such as pole and tower line images, equipment parameters, etc.) to determine whether there are faults such as line damage or abnormal equipment noise in the power equipment; if a fault is determined, in order to avoid delays in fault processing, the fault identification result will be marked as the highest priority to ensure that the information is transmitted first. During transmission, the edge processing device monitors the signal strength of the 5G communication module in real time. If the 5G signal strength is higher than the set threshold, it indicates that the current 5G network is stable. The fault identification result is then quickly sent to the remote monitoring center via the 5G communication module to ensure the timeliness of the information. If the 5G signal strength is not higher than the set threshold, it means that the 5G network cannot meet the stable transmission requirements. To avoid the loss of fault information, the fault identification result is used as key data and sent to the remote monitoring center via the Beidou short message communication module, which has a wide coverage and strong anti-interference capability, to ensure that the core fault information is not interrupted. At the same time, the fault identification result and the corresponding original inspection data (such as fault scene images and complete parameter records) are stored in the local storage unit. After the 5G communication module signal strength recovers, the original inspection data is sent to the remote monitoring center. This ensures the priority transmission of emergency fault information and also enables the retrospective and retention of complete inspection data.

[0121] As can be seen, in the technical solution provided in this embodiment, the power distribution network integrated communication system is equipped with edge processing equipment, a 5G communication module, switching equipment, a BeiDou short message communication module, and a BeiDou short message passive antenna. When the 5G communication channel signal quality is good, it prioritizes the transmission of large amounts of data via the 5G channel. When the 5G communication channel signal quality is poor, the inspection data is transmitted to the edge processing equipment via LoRa communication or wired transmission. The edge processing equipment then processes the existing data locally and transmits the processing results to the remote monitoring center with the highest priority via BeiDou short message communication. Therefore, the technical solution provided in this embodiment opens up multi-channel transmission and integrates these multi-channel transmissions, enabling timely and unimpeded transmission of inspection data to the remote monitoring center. Based on the integrated 5G and BeiDou communication and navigation power emergency technology, the high bandwidth and low latency of 5G allow for rapid acquisition of on-site information, enabling real-time monitoring and positioning of tower information. Simultaneously, the precise positioning function of the BeiDou navigation system improves the accuracy and reliability of monitoring. Furthermore, by constructing charging connection devices, comprehensive inspection information can be acquired and processed promptly through edge processing equipment on the pole side, with the results quickly transmitted to the remote monitoring platform. This demonstrates that building a unified information sharing platform enables data exchange and sharing among departments, improving operational efficiency and safety. Finally, with the assistance of an emergency command and dispatch system, sudden events can be responded to quickly, accidents can be effectively handled, and the operational safety of power infrastructure can be ensured. This provides users with a positive experience.
