Description

Technical Field

[0001] The present application relates to the field of power transmission line communication networks, and in particular to a power transmission line UAV communication networking system based on an optical fiber ring network. Background Art

[0002] Due to their long-term exposure to the outside world, transmission lines are very susceptible to factors such as channel environmental factors, meteorological factors such as typhoons and sandstorms, industrial and agricultural factors such as pollution and straw burning, as well as line problems such as rust and damage caused by long-term exposure to the air. These characteristics mean that the management and maintenance of transmission lines are extremely time-consuming and labor-intensive, and often fail to achieve ideal results.

[0003] Traditional power systems typically rely on regular inspections by staff to maintain and repair transmission line faults. This method is not only susceptible to the transmission line's geographical environment and weather factors such as rain and snow, which greatly complicates maintenance and repair work, but also requires staff to visit the line site at regular intervals for maintenance and repair. This not only consumes a significant amount of time, but also significantly depletes human, material, and financial resources. More importantly, manual inspections are not timely. Faults are typically discovered only after a period of time during routine inspections, making real-time monitoring impossible. This not only causes unnecessary delays in power work but can also lead to other power system issues caused by undetected line faults, further expanding the scope of power system faults. Therefore, traditional manual inspections for transmission line monitoring not only face challenges such as heavy workload, low maintenance and repair efficiency, and lengthy inspection cycles, but also, due to the widespread distribution, large coverage area, and long distances of transmission lines, manual inspections are virtually impossible to achieve comprehensive and detailed monitoring.

[0004] With the continuous advancement of power grid construction, various types of image / video online remote monitoring systems have been developed, as well as numerous monitoring units including wind deviation monitoring, ground circulation monitoring, tower tilt monitoring, conductor galloping monitoring, sag monitoring, hardware temperature measurement, icing monitoring, micrometeorological monitoring and conductor temperature measurement.

[0005] Furthermore, three-dimensional inspection methods, such as drones and drone airports, are gaining increasing popularity in power transmission line inspections due to their flexible maneuverability and multi-angle capabilities. Drones can carry sensors, cameras, and other equipment to conduct large-scale aerial inspections, overcoming limitations imposed by terrain and weather. They operate 24 / 7, significantly improving defect identification rates. Drones offer rapid response in emergencies. Multi-rotor drones, within wireless coverage, can quickly reach the site of a potential hazard, obtain immediate on-site data, and, combined with fixed-point hovering and voice-activated capabilities, rapidly implement corridor hazard control. Drone inspections provide workers with a more efficient and convenient means of monitoring the operational status of transmission lines, effectively ensuring operational safety.

[0006] However, the application of drones, an advanced transmission line inspection technology, also brings many challenges. The most prominent of these is the problem of drone communication on transmission lines. Drone communication currently relies heavily on the operator's shared network, facing problems such as limited communication bandwidth, poor data confidentiality, and the inability to jointly analyze relevant data in the first place. These problems have, to a certain extent, restricted the overall effectiveness of the drone transmission line inspection system. Summary of the Invention

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] In terms of the current capacity building of the existing transmission line network, limited by the coverage of wireless public networks, wireless public network communication bandwidth, high traffic fees, and limited energy storage supply of online monitoring devices, most areas only deploy drone airports in individual areas where potential hazards are relatively concentrated and wireless signal coverage is stable to carry out unmanned drone flight inspection tasks. The inspection missions are carried out at long intervals, and inspections of important transmission lines are only carried out once a month. At the same time, there are still factors in other areas that threaten the transmission line corridors, making it impossible to achieve the goal of unmanned and fully automatic inspection of the entire line.

[0032] In terms of communication distance. During the inspection of transmission lines by drones, the communication problems faced mainly include the limitation of communication distance, signal obstruction caused by complex terrain, insufficient data security and bandwidth when using public networks, the difficulty in efficiently transmitting high-data-volume images and videos, and communication coordination problems when multiple drones work together. Specifically, the communication between the drone and the ground control station may be affected by the long flight distance, resulting in signal weakening or interruption; complex terrain features such as mountains and forests may hinder signal transmission and affect the stability of communication. These interferences not only affect the normal communication of the drone, but may also affect the stable transmission of flight control commands and aerial image data, thereby affecting the efficiency and accuracy of the inspection, further affecting the normal operation of the drone, and may even cause the drone to crash.

[0033] Regarding the timeliness of data feedback. Current drone-based lean inspections of power transmission lines collect a massive amount of high-definition images and video data daily, generating a massive amount of data. However, since the areas through which power transmission lines pass often have issues such as insufficient public network bandwidth, poor network signals, and lack of cellular network coverage, this data cannot be transmitted to the data management platform in real time. In most cases, manual copying is used to bring data that cannot be reported on-site back to the business center for upload to the platform. This results in the backend being unable to obtain timely warning data on existing network line defects and faults, making it impossible to respond immediately. Furthermore, there are some prominent security issues. Therefore, resolving these communication issues is an important prerequisite for ensuring the smooth progress of drone inspections.

[0034] Regarding data security, manual copying can lead to human errors, such as incomplete or erroneous data copying, which can affect data accuracy and integrity. Furthermore, the data collected by drone inspections of power transmission lines often contains a large amount of personal privacy and commercial confidential information. Traditional methods such as manual copying and transmission can create the risk of data being accessed, stolen, or even tampered with by unauthorized personnel. If this data is leaked or used maliciously, it will cause immeasurable losses to the parties involved.

[0035] In terms of comprehensive data aggregation for multi-UAV collaborative operations. UAV collaborative operations are highly dependent on efficient communication systems. When performing tasks such as power line inspections, multiple UAVs need to exchange key information such as location information, sensor data, and mission status in real time to ensure coordinated actions and avoid collisions. This highly integrated information sharing requires communication links with sufficient bandwidth, low latency, and high reliability so that UAVs can respond instantly to environmental changes and status updates from other UAVs. Once communication is interrupted or delayed, it will not only affect the efficiency and accuracy of mission execution, but may also lead to serious safety issues such as UAV loss of control or collision accidents. Currently, each UAV's autonomous inspection process operates independently. The existing power line communication network cannot support real-time information exchange among multiple UAVs, let alone guarantee efficient collaborative operations.

[0036] Based on this, the purpose of this application is to provide a transmission line drone communication networking system based on optical fiber ring network to ensure timely, safe and efficient large-scale data transmission.

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] The transmission line drone communication networking system based on the optical fiber ring network provided in this application includes multiple integrated base stations; multiple integrated base stations form an optical fiber ring network through OPGW optical cables and LTE MESH self-organizing networks; drones performing transmission line inspection tasks and corresponding fixed airports are connected to the information intranet through the optical fiber ring network.

[0039] Among them, the integrated base station includes OPGW integrated base station and MESH integrated base station. Figure 1 As shown in the figure, the OPGW integrated base station is deployed at a node on the transmission line tower with a fiber optic splice box and is connected to the information intranet through a wired connection. The MESH integrated base station is deployed at a node on the transmission line tower without a fiber optic splice box and is connected to the OPGW integrated base station through a wireless connection.

[0040] Construction of a multi-mode intelligent integrated base station (OPGW) for the power grid. In order to ensure the real-time, integrity, confidentiality, security and comprehensive data collection and aggregation of transmission line drone inspection data, this application utilizes the existing advantages of the OPGW optical cable for the transmission line, and deploys a multi-mode intelligent integrated base station (OPGW) node for the power grid at a location with an optical fiber junction box on the transmission line tower to achieve multi-line communication transmission. The multi-mode intelligent integrated base station for the power grid covers a radius of 10km, and adjacent towers can be within 10km apart, so that there is a signal overlapping coverage area, which can provide roaming self-organizing network switching for the drone end. At the same time, if there are key towers within a 10km range that need to deploy a multi-mode intelligent integrated base station (OPGW) node for the power grid, a more reliable signal transmission network can be achieved. This node can be used for backup coverage through the switching system when a problem occurs with the multi-mode intelligent integrated base station (OPGW) node for the power grid.

[0041] Grid Multimode Intelligent Integrated Base Station (MESH) Construction. At nodes on transmission line towers without fiber optic splice boxes, Grid Multimode Intelligent Integrated Base Stations (OPGWs) on other transmission line towers can be used for point-to-point single-hop (or multi-hop) MESH signal network coverage. Transmission line towers are selected as Grid Multimode Intelligent Integrated Base Station (MESH) nodes. Wireless communication links expand the wireless signal coverage range, achieving communication environment coverage in nearby areas not covered by fiber-optic composite overhead ground wires. The coverage radius can also reach 10km, reducing the delay caused by the increase in hops and achieving a reliable signal transmission network.

[0042] like Figure 1 As shown, the drone is wirelessly connected to the OPGW integrated base station. The OPGW integrated base station is wired to the OPGW optical cable. The drone is wirelessly roaming with the MESH integrated base station. A wireless connection is a connection between the drone and the wireless network of the base station in the area to which the drone belongs. However, the drone may fly to the edge of its area. When the drone reaches the edge of the area, the signal from the base station outside the area is stronger. The base station can use wireless roaming to temporarily transfer communication management rights to its jurisdiction.

[0043] The OPGW and MESH multi-mode intelligent integrated base station (OPGW and MESH) is a 1.4GHz and 5.8GHz dual-mode wireless private network base station (powered by photovoltaic and lithium batteries) for drone access and data backhaul. It ensures stable communication between drones and the integrated base station at varying distances (up to 12km), altitudes (under 120m), and orientations.

[0044] The multi-mode intelligent integrated base station for the power grid is installed on the transmission tower. Based on the design concept of wireless communication self-organizing network, it realizes the construction of the transmission line LTE base station MESH wireless communication link self-organizing network, ensuring the comprehensive data collection and aggregation of drones and drone airports, AI analysis, joint research and alarm, and unified upload. It uses standard communication interfaces and protocols to connect to various drones and fixed airport inspection equipment, and connects to the upper-level drone management platform through standard communication protocols and data models. System architecture see Figure 2 .

[0045] like Figure 2 As shown, drones and fixed airports communicate with the integrated base station via a 1.4G wireless communication link. The MESH integrated base station communicates with the OPGW integrated base station via a 5.8G wireless communication link. The OPGW integrated base station communicates with the information intranet via optical fiber. For uplink data collection, drone and fixed airport data is uploaded to the integrated base station (OPGW or MESH) via a 1.4G wireless communication link; data from the integrated base station (MESH) is uploaded to the integrated base station (OPGW) via a 5.8G wireless communication link; and data from the integrated base station (OPGW) is uploaded to the information intranet via optical fiber. Downlink command and control data can be transmitted in the opposite direction.

[0046] Furthermore, the transmission line drone communication networking system also includes a security gateway. The fiber optic ring network is connected to the information intranet through the security gateway. The security gateway is used to achieve secure isolation between the fiber optic ring network and the information intranet. Specifically, the security gateway is a gateway responsible for communication network security. It can identify and exclude communication data from other external systems attempting to infiltrate the information intranet. It can also encrypt downlink control commands to prevent information theft by other external systems.

[0047] OPGW ring communication networking, that is, optical fiber ring network construction. Figure 2 The communication network shown is a local unit UAV communication network, which describes a minimum unit communication network. More than one communication unit can form a complete communication network covering the entire area. OPGW ring communication network refers to a complete communication network formed by ring splicing, see Figure 3. It should be noted that the OPGW ring communication network can have one or several large rings, and some small rings can be nested in the large ring. From the overall structure, it is similar to a ring communication network. Compared with the straight-line communication network, its coverage is more complete. Specifically, based on the transmission method of LTE MESH self-organizing network wireless communication, by installing trunk transmission equipment (OPGW optical cable, that is, the optical fiber in the overhead ground wire of the transmission line) using long-distance point-to-point and point-to-multipoint technology in the substation, the 1.4G frequency band (1438MHz~1444MHz) is used for transmission, and with high-gain antennas up to 10km of transmission distance, it can provide a maximum bandwidth of 200Mbps, support the transmission of multiple services such as video, flexible networking, and easy installation and expansion. The ring network is equipped with a 1.4G wireless access hotspot, which can realize data access for inspection equipment such as drones and fixed airports within a range of 5km~10km on both sides of the line. For some monitoring points that do not have an OPGW integrated base station, the data is first transmitted to a nearby tower with an OPGW integrated base station via 5.8G wireless transmission, and then transmitted via the OPGW optical cable.

[0048] like Figure 3 and Figure 4 As shown, the security gateway is a micro-security authentication device, and drones, fixed airports, and integrated base stations are equipped with security encryption chips. These drones, fixed airports, and integrated base stations use the security encryption chip's security encryption certificate to authenticate secure access and encrypt and decrypt data transmission with the micro-security authentication device. Authenticated drones, fixed airports, and integrated base stations then access the information intranet.

[0049] Furthermore, the transmission line drone communication networking system also includes a ring network management device. The fiber optic ring network is connected to the information intranet via the ring network management device and a micro security authentication device. The ring network management device is used to centrally manage data transmission within the fiber optic ring network. Specifically, the ring network management device is a station-side management device responsible for fiber optic communications within the overhead ground wires of the transmission line, centrally managing both uplink and downlink transmission of fiber optic ring network data.

[0050] Internal and external networks are securely isolated. Figure 4As shown, data transmission utilizes an OPGW fiber ring network + 1.4G wireless broadband + 5.8G wireless broadband + LTE base station mesh ad hoc network communication solution. All drones, fixed airports, and integrated base stations are equipped with security encryption chips. Before the substation enters the Synchronous Digital Hierarchy (SDH) private network, a micro-security authentication device is installed. This securely isolates communications between tower-mounted equipment (including monitoring terminals such as drones and fixed airports) and the information intranet, ensuring the security of the intranet. Drones, fixed airports, and integrated base stations are equipped with security encryption chips. Using security encryption certificates, they implement secure access authentication and data encryption and decryption transmission with the micro-security authentication device. This ensures that data transmitted over the OPGW fiber ring network + 1.4G wireless broadband + 5.8G wireless broadband + LTE base station mesh ad hoc network is encrypted, ensuring data security. Furthermore, only one micro-security authentication device is required to ensure the security of the information intranet.

[0051] like Figure 5 As shown, drones and fixed airports are also equipped with radio transceivers (RTs), specifically devices (such as built-in antennas) that transmit and receive communication data between drones and fixed airports. The integrated base station is also equipped with a wireless access point (AP), which typically includes one or more antennas, as well as the necessary hardware and software to handle the transmission and reception of wireless signals. Its function is to connect wireless devices (such as drones and fixed airports) to the integrated base station (OPGW and MESH), enabling drones and fixed airports to access network resources wirelessly. The radio transceiver accesses the wireless access point via a wireless connection.

[0052] The wireless access point is set to be hidden. UAVs and fixed airports use radio transceivers to authenticate access passwords with the wireless access point. Authenticated drones and fixed airports then access the integrated base station.

[0053] Wireless access network security methods. To ensure the security of wireless access networks, supported security mechanisms include access authentication, wireless signal stealth, whitelisting, isolation of unauthorized access terminals, anti-DoS attack capabilities, and anti-port scanning capabilities.

[0054] Access authentication: supports MAC address access control management, and the device needs to pass the access password authentication when wirelessly accessing the integrated base station. Only when the password authentication is passed can it access.

[0055] Wireless signal invisibility: The wireless access hotspot of the integrated base station is set to be hidden, ensuring that the network cannot be accessed without knowing the access signal.

[0056] Whitelist mechanism: Add a whitelist of devices allowed to access to the integrated base station. Monitoring terminals not on the whitelist cannot access the device. It has the ability to prevent DoS attacks and port scanning.

[0057] Illegal access terminal isolation: The integrated base station monitors the access requests of access devices in real time. When an abnormal situation occurs and the security module identifies it as an illegal intrusion, the access device is immediately isolated, added to the blacklist and an alarm is issued.

[0058] Air interface data transmission: Air interface data transmission supports AES256 encryption, ensuring that the data content cannot be decrypted without knowing the public key.

[0059] This application deploys multi-mode intelligent integrated base station nodes in the power grid and establishes a transmission line drone communication networking system based on a fiber optic ring network, thereby achieving full coverage of the transmission line wireless private network. While ensuring information security, it provides large communication bandwidth support for multi-machine joint inspections across the entire area by drones, realizes real-time feedback of inspection data, and automatically organizes it on an artificial intelligence platform, thereby improving inspection operation efficiency.

[0060] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core concept of this application. At the same time, for those skilled in the art, based on the concept of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
