Abstract
Description

[0002] With the advancement of digital grid construction, the inspection of wired power data networks has gradually evolved from "primarily human inspection" to "primarily drone inspection, supplemented by human inspection," basically achieving intelligent inspection of wired power data networks and realizing comprehensive coverage of wired power data networks by unmanned aerial vehicle (UAV) automatic inspection. Current UAV intelligent inspection mainly relies on ground-based augmentation systems to provide RTK high-precision positioning services. The positioning terminal receives error term signals from nearby reference stations, calculates accurate carrier positioning results, and thus calculates the precise location information of the terminal and the UAV.
[0003] Intelligent inspection by drones requires high-precision positioning services from ground-based augmentation systems. The interconnection between these systems and positioning terminals primarily relies on mobile networks operated by carriers. However, when there is no mobile network coverage in the field, the positioning terminals cannot achieve centimeter-level precision positioning, thus hindering power grid companies from implementing intelligent drone inspections using wired power data networks. Furthermore, wired power data networks are typically located in remote areas, often traversing mountainous regions with poor mobile network coverage, significantly limiting the effectiveness of existing positioning terminals in these areas and preventing the implementation of intelligent drone inspection services. Therefore, it is urgent to overcome the communication bottleneck between positioning terminals and ground-based augmentation systems to address the pain points of intelligent inspection in power grid transmission scenarios.

[0058] The terms “comprising” and “including” indicate the presence of the described feature, whole, step, operation, element and / or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.

[0060] See Figure 1 , Figure 1 A high-precision RTK positioning terminal with a multi-mode communication link is provided, including modules 01-06. Specifically, the functions of each module are as follows:
[0061] GNSS receiver module 01 is used to receive signals from multiple GNSS satellites, calculate the pseudorange between each satellite and the terminal, and calculate the latitude, longitude and elevation information of the positioning terminal.
[0062] The routing module 02 is used to calculate the optimal communication link based on link status, communication bandwidth, communication latency and packet loss rate information.
[0063] This module can perform communication link routing selection. By comprehensively judging information such as link status, communication bandwidth, communication latency, and packet loss rate, it calculates and selects the optimal communication link under the current conditions, and then notifies the communication module 03 to carry out the data transmission process.
[0064] The communication module 03 is used to transmit data according to the optimal communication link selected by the routing module 02.
[0065] The RTK calculation module 04 is used to summarize the information from the GNSS receiving module 01 and the communication module 03. It calculates high-precision positioning information by combining the positioning error term of the ground-based augmentation system with its own positioning information, thereby realizing the high-precision position required for intelligent inspection of UAVs.
[0066] The UAV interaction module 05 is used to transmit the high-precision positioning information to the UAV so that the UAV can perform high-precision inspection.
[0067] This module is used to transmit the high-precision positioning information of the positioning terminal to the UAV through the interaction module, as one of the input information for the inspection UAV's autonomous intelligent flight inspection, thus meeting the requirements of high-precision inspection positioning.
[0068] The main control module 06 is used to realize information interaction with all modules, and to complete data processing, command sending and receiving, and status acquisition.
[0069] Please see Figure 2 , Figure 2 A schematic diagram of the structure of an RTK high-precision positioning terminal with a multi-mode communication link is provided for another embodiment of this application.

[0071] Specifically, the wireless public network communication module 031 is divided into two types of sub-modules: a 4G wireless communication sub-module and a 5G wireless communication sub-module. The wireless public network communication module 031 accesses the operator's mobile public network through wireless channels such as 4G and 5G, and is used to send terminal location information and receive positioning error terms broadcast by the ground-based augmentation system.
[0072] Satellite communication module 032 is used to communicate and interconnect with communication satellites to obtain high-precision positioning information; the communication satellites include maritime, Tiantong, and low-Earth orbit communication satellites;
[0073] Specifically, the satellite communication module 032 is divided into three sub-modules: a maritime satellite communication sub-module, a Tiantong satellite communication sub-module, and a low-Earth orbit (LEO) satellite communication sub-module. The satellite communication module 032 enables communication interconnection with maritime, Tiantong, and LEO communication satellites, and facilitates data exchange with ground-based augmentation systems via these satellites to acquire high-precision positioning information.
[0074] The fiber optic communication module 033 is used to access the power wired data network via a fiber optic interface to interact with the ground-based augmentation system through the internal power network and obtain high-precision positioning information. The power wired data network includes OPGW, IOPPC, etc.
[0075] In areas where conditions permit, access to power wired data networks such as OPGW and IOPPC can be achieved through fiber optic interfaces. Subsequently, data exchange with the ground-based augmentation system can be conducted through the internal power network to obtain high-precision positioning information.
[0076] In one specific embodiment, based on the RTK high-precision positioning terminal with multi-mode communication link provided in the above embodiments, an RTK high-precision positioning method with multi-mode communication link is also provided. For example... Figure 1 As shown, the RTK high-precision positioning method with multi-mode communication link includes steps S10 to S40. The specific steps are as follows:
[0077] Step S10: Power on the multi-mode RTK communication positioning terminal and complete the initialization startup;
[0078] Step S20: Establish a communication link with the ground-based augmentation system and upload relevant information to the ground-based augmentation system;
[0079] Step S30: Complete GNSS signal reception, obtain preliminary location information, and upload the location information to the ground-based augmentation system through adaptive selection of communication link;
[0080] Step S40: Adaptively receive RTK error information sent by the ground-based augmentation system and calculate precise positioning information.
[0081] It should be noted that once the multi-mode RTK communication positioning terminal is started, accurate positioning can be achieved by completing steps S20-S40 on the terminal.
[0082] See Figure 4 In one specific embodiment, step S20, establishing a communication link with the ground-based augmentation system, includes the following sub-steps:

[0084] Step S2011: Use the wireless public network communication module 031 to access the wireless base station, complete the registration and activation on the operator's mobile network, and return the result to the main control module 06 after the wireless public network communication link is established.
[0085] Step S2012: Use satellite communication module 032 to access the satellite system, complete link registration, and return the result to main control module 06;
[0086] Step S2013: Use the fiber optic communication module 033 to access the power wired data network, and return the result to the main control module 06 after the link access is completed; wherein, the power wired data network includes OPGW and IOPPC.
[0087] See Figure 5 In one specific embodiment, step S30, which involves uploading location information to the ground-based augmentation system via adaptive selection of a communication link, includes:
[0088] Step S301: Complete GNSS signal reception through GNSS receiving module 01 to form its initial positioning; it should be noted that in this step, the terminal can receive global satellite navigation signals such as Beidou, GPS, Galileo, and GLONASS according to the GNSS signal conditions, complete the calculation of its own position information, and feed the results back to the main control module 06.
[0089] Step S302: The routing module 02 adaptively selects a communication link based on the communication link status, communication bandwidth, communication latency, and packet loss rate information fed back by each communication module 03, and feeds the result back to the main control module 06; the adaptive routing selection parameters are shown in Table 1:
[0090] Table 1 Routing Adaptive Selection Parameter Table
[0091]
[0092] In one exemplary embodiment, the algorithm for adaptive communication link selection is as follows:
[0093]
[0094] In the formula, f(x) represents the sum of routing parameters for each communication link. LSQ, BWR, DelayR, and LossR are normalized parameter values ranging from 0 to 1. α, β, etc., are coefficients of each parameter, which can be dynamically adjusted according to link selection requirements. Finally, the communication link with the highest parameters is selected using the formula as the communication channel between the terminal and the ground-based augmentation system.
[0095] Step S303: Upload its own location information to the ground-based augmentation system through the communication link.
[0096] See Figure 6 In one specific embodiment, step S40, the adaptive reception of RTK error information sent by the ground-based augmentation system, includes:
[0097] Step S401: Receive the RTK error information of the ground-based augmentation system through the communication link selected by the route, and calculate the accurate self-positioning information;
[0098] Step S402: Use communication module 03 to collect various parameter information during communication, including LSUD, LSQ, BWR, Delay, and LossR information. Among them, LSUD and LSQ are collected normally, while BWR, Delay, and LossR are received and calculated after each communication.
[0099] In summary, given that power transmission lines are typically located in remote areas, many of which traverse mountainous regions where mobile network coverage is limited, the application of existing positioning terminals and drone-based intelligent inspection services in these areas is severely restricted. This application addresses the pain points of intelligent inspection in power grid companies' transmission scenarios by providing a stable and reliable multi-mode communication link for RTK positioning terminals. This effectively ensures rapid positioning of high-precision positioning terminals and meets the high-precision positioning requirements in complex electromagnetic compatibility environments in the power industry.
