[0047] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] refer to Figure 1 to Figure 2 , a communication cable laying construction method for complex terrain, specifically comprising:

[0049] Obtain three-dimensional data of complex terrain and build a terrain model based on the three-dimensional data;

[0050] Based on the terrain model and construction requirements, simulated annealing algorithm is used for path planning to generate the communication cable laying path;

[0051] Based on the communication cable laying path, an adaptive cable laying robot is used to lay the communication cables;

[0052] Acquire various data and on-site images during the construction process to the monitoring center in real time;

[0053] The monitoring center determines the construction status based on the acquired data and on-site images.

[0054] In this embodiment, by acquiring three-dimensional data of complex terrain and establishing an accurate terrain model, a detailed terrain basis can be provided for the laying of communication cables, thereby improving the accuracy of path planning. By using the simulated annealing algorithm for path planning, multiple factors such as terrain undulation, obstacle distribution, and construction cost can be comprehensively considered to generate the optimal cable laying path, thereby improving construction efficiency. The application of the adaptive cable laying robot can automatically adjust the walking posture and cable laying speed in complex terrain to ensure uniform cable tension and avoid excessive stretching or bending, thereby reducing safety risks during the construction process. Various data and on-site images during the construction process can be obtained in real time to the monitoring center, so that management personnel can understand the construction situation in a timely manner, discover problems in a timely manner and take countermeasures, thereby further improving construction safety. By optimizing path planning, the cable length and unnecessary material consumption can be reduced, thereby reducing construction costs. The use of efficient construction equipment and processes can improve construction efficiency, reduce manpower and time investment, and further save resources.

[0055] Preferably, the step of acquiring three-dimensional data of complex terrain and establishing a terrain model based on the three-dimensional data specifically includes:

[0056] Obtain point cloud data and geological survey data of terrain surface;

[0057] Preprocessing of point cloud data and geological survey data of terrain surface;

[0058] Three-dimensional modeling is performed based on the pre-processed point cloud data of the terrain surface and the geological survey data to construct a three-dimensional digital model of the terrain.

[0059] In this embodiment, by acquiring point cloud data of the terrain surface, it is possible to capture the tiny undulations and details of the terrain surface, including peaks, gullies, vegetation coverage, etc., thereby achieving an accurate description of complex terrain and supplementing geological survey data, further revealing underground geological structure, rock layer distribution, soil type and other information, providing a comprehensive terrain cognition basis for construction; preprocessing the point cloud data and geological survey data of the terrain surface, such as denoising, filtering, and registration, can improve the reliability and availability of the data, and provide a high-quality data source for subsequent 3D modeling. The accurate terrain model provides a reliable basis for planning the laying path of communication cables, and the use of the terrain The three-dimensional terrain model can comprehensively consider factors such as terrain undulations, obstacle distribution, geological conditions, etc., formulate the optimal paving path, reduce construction difficulty and cost, and the accurate terrain model and scientific construction plan provide the construction team with clear construction guidance, reduce the workload of on-site investigation and measurement, and improve construction efficiency. The three-dimensional terrain model can also be combined with the construction monitoring system to obtain various data and on-site images during the construction process in real time, and compare and analyze them with the terrain model to promptly discover and correct construction deviations. Through real-time monitoring and data analysis, the construction team can more accurately grasp the construction progress and quality to ensure that the construction proceeds smoothly as planned.

[0060] Preferably, the method of performing path planning based on the terrain model and construction requirements by using a simulated annealing algorithm to generate a communication cable laying path specifically includes:

[0061] Step S1: Generate an initial communication cable laying path based on the terrain model and construction requirements;

[0062] Step S2: adjusting the initial communication cable laying path to generate multiple neighborhood solutions;

[0063] Step S3, calculating the cost of each neighborhood solution;

[0064] Step S4, comparing the cost of each neighborhood solution with the cost of the current solution according to the probability acceptance criterion of the simulated annealing algorithm;

[0065] Repeat steps S2 to S4, continuously generate new neighborhood solutions, calculate costs, and update the current solution according to the probability acceptance criterion. Through multiple iterations, the algorithm will gradually converge to an optimal communication cable laying path.

[0066] In this embodiment, through the global search capability of the simulated annealing algorithm, it is possible to avoid difficult-to-construct areas (such as steep peaks, deep valleys, etc.) in complex terrain, automatically find and generate the optimal communication cable laying path, which greatly reduces the time cost of manual survey and planning, and improves the rationality and scientificity of the path; the optimized laying path reduces unnecessary bending and detours, reduces the use of cables and the difficulty of construction, thereby improving the overall construction efficiency. In complex terrain, this optimization is particularly significant and can significantly shorten the construction period; due to the optimization of the path, the consumption of cable materials, construction equipment and human resources is reduced, thereby directly reducing the construction cost. At the same time, the optimized path can also reduce the subsequent maintenance cost and failure rate, further improving the economic benefits; the optimized path reduces the bending and stretching of the cable, helps to maintain the stable transmission of the signal and improve the communication quality. In complex terrain, this is particularly important because the undulations and obstacles of the terrain often interfere with signal transmission; the simulated annealing algorithm has strong adaptability and robustness, and can automatically adjust parameters and strategies according to different terrain characteristics and construction requirements to generate the optimal laying path, which makes the application of this technical solution in different complex terrains have wide adaptability and flexibility.

[0067] It should be noted that the initial path generation: based on the terrain model and construction requirements, a feasible communication cable laying path is preliminarily determined as the initial solution;

[0068] Neighborhood generation: Adjust the current path to generate a series of neighborhood solutions. These adjustments may include changing the direction, length or height of certain sections of the path.

[0069] Cost calculation: Cost calculation is performed for each neighborhood solution. The specific formula for cost calculation will be designed based on multiple factors such as project requirements, terrain characteristics, construction difficulty, etc., and may include cable material costs, construction time, environmental impact assessment, etc.

[0070] Probabilistic acceptance criterion: Compare the cost of each neighborhood solution with the cost of the current solution. If the cost of the neighborhood solution is lower, then directly accept the solution as the new current solution. If the cost of the neighborhood solution is higher, then according to the probabilistic acceptance criterion of the simulated annealing algorithm, the solution is accepted with a certain probability. This probability is usually related to the "temperature" parameter. As the algorithm iterates, the "temperature" gradually decreases, and the probability of accepting a worse solution also gradually decreases;

[0071] Iterative update: Repeat steps 2 to 4 to continuously generate new neighborhood solutions and update them according to the probability acceptance criterion until certain stopping conditions are met (such as reaching the preset number of iterations, the temperature drops to a low enough level, and the solution does not change significantly after multiple consecutive iterations, etc.);

[0072] Optimal solution output: When the algorithm stops, the current solution is the final optimal communication cable laying path.

[0073] Preferably, the adaptive cable laying robot comprises:

[0074] Perception system, used to perceive the surrounding environment and cable status in real time;

[0075] A crawler or wheeled walking module, used to adopt different walking modes according to different terrains, wherein the walking modes include a crawler walking mode and a wheeled walking mode;

[0076] The terrain adaptation adjustment mechanism is used to adjust the walking posture and height in real time according to the ups and downs of the terrain and the changes in slope;

[0077] Cable laying module, used to control the laying speed and tension of cables;

[0078] A mechanical auxiliary arm is used to assist the robot in crossing obstacles, providing stable support and guiding cable laying;

[0079] The power and control system is used to provide the robot with power and generate control instructions for the robot.

[0080] In this embodiment, the perception system equipped with the robot can perceive the surrounding environment and cable status in real time, ensuring accurate judgment and response to various situations in complex terrain; the design of the crawler or wheeled walking module enables the robot to flexibly switch walking modes according to terrain changes, improving the passability and stability on different terrains; the terrain adaptation adjustment mechanism can adjust the walking posture and height in real time according to the ups and downs of the terrain and the changes in slope, ensuring the stability and accuracy of the cable laying process; the cable laying module accurately controls the laying speed and tension of the cable to avoid damage to the cable due to excessive stretching or bending, thereby improving the construction quality; the addition of the mechanical auxiliary arm enables the robot to easily cross obstacles such as gullies, rocks, etc., ensuring the continuity of construction. In addition to improving the robot's safety and efficiency, the auxiliary arm can also provide stable support and guide cable laying, especially in complex terrain, to ensure that the cables can be accurately laid along the predetermined path; the power and control system, as the core of the robot, not only provides the power source, but is also responsible for generating control instructions to realize the robot's intelligent and automated operation. This intelligence and automation improves construction efficiency and reduces the risks and costs of manual operation; by precisely controlling the laying speed and tension of the cable, as well as the stable support and guidance of the mechanical auxiliary arm, the adaptive cable laying robot can ensure the laying quality of the cable in complex terrain, which not only improves the transmission performance of the communication cable, but also extends the service life of the cable, enhancing the reliability and stability of the communication system.

[0081] Preferably, a multi-layer composite structure sheath is provided on the outside of the communication cable, and the multi-layer composite structure sheath includes an outer protective sheath, a middle protective sheath and an inner protective sheath, the outer protective sheath is made of polymer material, the middle protective sheath is made of fiber material, and the inner protective sheath is made of water-absorbing and swelling material or anti-corrosion coating material.

[0082] In this embodiment, the design of the multi-layer composite structure sheath significantly enhances the durability of the communication cable. The outer protective sheath is made of polymer material, which provides basic mechanical strength and wear resistance, and can resist external physical impact and wear; the middle protective sheath is made of fiber material (such as carbon fiber reinforced polymer, Kevlar fiber, etc.), which further improves the tensile strength and shear resistance of the cable, ensuring that the cable is not easy to break or damage in complex terrain; the inner protective sheath is made of water-absorbing and swelling material or anti-corrosion coating material, which provides targeted protection. The water-absorbing and swelling material can expand rapidly when the sheath is damaged to prevent further water intrusion, which is particularly suitable for humid or swampy areas, while the anti-corrosion coating material can effectively prevent the cable from being corroded by chemical substances and is suitable for corrosive environments; the multi-layer structure design enables each layer to play a specific protective role, and together form a strong protective barrier. This comprehensive protective effect greatly improves the survivability and service life of communication cables in complex terrain; by enhancing the durability and protective performance of the cable, the multi-layer composite structure sheath can reduce the number of repairs and replacements due to cable damage, thereby reducing long-term maintenance costs; because the cable has better protective performance, additional protective measures for the cable can be reduced during construction, thereby simplifying the construction process and improving construction efficiency.

[0083] It should be noted that the polymer materials include but are not limited to the following polymer materials with good weather resistance, such as polyethylene, polyvinyl chloride, polyurethane and fluoroplastics, which are not specifically limited here; in addition, polymer materials with excellent flexibility and wear resistance are selected as filling materials, such as high-elastic polyurethane foam, silicone rubber, etc. These materials can provide good buffering and support when the cable is bent, reduce the stress concentration and wear of the cable caused by bending, and fill the filling material inside the sheath to form a continuous protective layer around the cable core wire. The filling material can also be designed into a deformable structure to better adapt to changes in complex terrain; in addition, recyclable or biodegradable materials are selected as components of the cable sheath and filling materials to reduce pollution to the environment. During the construction process, environmentally friendly construction equipment and materials are used in conjunction, such as low-noise, low-emission construction machinery and degradable laying auxiliary materials to further reduce the impact on the environment.

[0084] Preferably, a sensor group is embedded in the multi-layer composite structure sheath to monitor the status and environmental parameters of the communication cable in real time.

[0085] In this embodiment, small sensors (such as tension sensors, temperature sensors, humidity sensors, etc.) are embedded in the multi-layer composite structure sheath to monitor the status and environmental parameters of the cable in real time. These sensors are connected to the adaptive cable laying robot or the remote monitoring center by wireless means to transmit real-time data. According to the data fed back by the sensors, the adaptive cable laying robot can adjust the laying speed and cable tension to avoid excessive stretching or bending. At the same time, the remote monitoring center can also adjust the construction strategy or issue a warning signal in time according to the data analysis results. When the sensor detects an abnormality (such as excessive cable tension, excessive temperature, excessive humidity, etc.), the system can automatically trigger the warning mechanism to notify the construction personnel to take corresponding measures. In addition, through the analysis of long-term monitoring data, the life and maintenance needs of the cable can also be predicted, and maintenance work can be arranged in advance.

[0086] Preferably, the real-time acquisition of various data and on-site images during the construction process to a monitoring center specifically includes:

[0087] Deploy multiple drones in complex terrain areas to form a drone swarm;

[0088] The drone establishes a real-time data link with the communication satellite;

[0089] The real-time data collected by the drone is encrypted and sent to the cloud AI data analysis platform, which performs real-time analysis on the data sent back by the drone.

[0090] The analysis results are presented in the form of a three-dimensional model on the screen of the monitoring center.

[0091] In this embodiment, the drone cluster can fully cover the complex terrain area, collect various data (such as cable tension, temperature, humidity, etc.) and on-site images during the construction process in real time, ensure the comprehensiveness and real-time monitoring, and establish a real-time data link between the drone and the communication satellite to ensure the high speed and stability of data transmission, and reduce the delay and packet loss of data transmission; the real-time data collected by the drone is encrypted and then sent to the cloud AI data analysis platform, which effectively ensures the security of the data during transmission and prevents data leakage and illegal access. The cloud AI data analysis platform performs real-time analysis on the data sent back by the drone, and uses big data and artificial intelligence technology to quickly identify problems in construction, such as abnormal cable tension. The system can identify problems such as irregularities, delayed construction progress, etc., and provide timely decision-making support for the monitoring center; the analysis results are presented in the form of a three-dimensional model on the screen of the monitoring center, making the situation on the construction site more intuitive and three-dimensional, which helps monitoring personnel to quickly understand the construction status, accurately judge construction problems, and improve decision-making efficiency and accuracy; real-time monitoring and intelligent analysis can promptly discover problems and hidden dangers in construction, and take timely measures to solve them, avoiding the accumulation and expansion of problems, thereby improving construction efficiency and quality; through real-time monitoring and data analysis, potential safety risks can be warned in advance, such as signs of natural disasters such as landslides and collapses, as well as construction equipment failures, so that preventive measures can be taken in time to reduce safety risks in the construction process.

[0092] It should be noted that multiple drones are deployed in complex terrain areas to form drone clusters. These drones are equipped with high-definition cameras, thermal imagers, environmental sensors (such as temperature and humidity, air pressure, wind speed, etc.) and dedicated satellite communication equipment. The drones establish real-time data links through low-orbit satellites or directly with high-orbit communication satellites to ensure stable data transmission even in areas with complex terrain and insufficient network coverage.
