Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a surveying and inspection integrated mobile platform for satellite chain communication and a mobile platform control method. BACKGROUND

[0002] With the continuous expansion of global infrastructure construction, a large number of engineering projects are located in remote areas where communication and power infrastructure is extremely weak. In such project sites, it is crucial to achieve efficient daily inspection, engineering surveying and real-time data transmission to ensure construction safety and monitor project progress. Unmanned aerial vehicle (UAV) inspection and aerial surveying technology, as an effective means of modern engineering management, should play a core role in such scenarios due to its flexibility and efficiency. However, existing technical solutions cannot meet this demand and have obvious limitations.

[0003] Firstly, in terms of communication, traditional ground base station deployment is costly and time-consuming, making it unsuitable for temporary or rapidly shifting projects. Portable 4G / 5G communication equipment is limited by operator network coverage and completely ineffective in areas without signal. Secondly, in terms of power support, project sites often lack stable high-power mains electricity, and single generator power supply is noisy, energy-intensive and not environmentally friendly. Pure battery solutions are limited by limited battery life and cannot support high-power systems such as UAV airfields and servers for long-term continuous operation. Finally, in terms of data processing, existing solutions often have "information silos" problem. UAV-collected data needs to be manually retrieved from storage devices and then sent to the rear for processing, which is a tedious and time-consuming process. This results in a serious time delay between data collection and the formation of results that can be used for decision-making, which cannot meet the real-time requirements of site management.

[0004] In summary, the existing technology mainly has the following technical problems to be solved: how to build a mobile operation platform that meets the communication and inspection requirements in remote areas overseas to solve the technical problems of unstable communication and low inspection efficiency in remote areas. SUMMARY

[0005] Therefore, it is necessary to provide a surveying and inspection integrated mobile platform for satellite chain communication and a mobile platform control method to solve the technical problems of unstable communication and low inspection efficiency in remote areas.

[0006] To solve the above technical problems, in a first aspect, the present application provides a surveying and inspection integrated mobile platform for satellite chain communication, which is based on a mobile carrier and integrates a satellite communication system, a power system, a flight system, a vehicle-mounted server, a flight control system and a surveying and computing system. The satellite communication system uses satellite chain satellite communication equipment to provide internet access for the entire platform. The power system comprises an outdoor mobile power supply, a gasoline generator and an external power supply interface, and is configured with a power management unit for automatic switching and management between multiple power supplies, wherein the outdoor mobile power supply is configured as the main power source of the system. The flight system is an integrated unmanned aerial vehicle platform deployed on the mobile carrier; The flight control system and the surveying and mapping operation system are installed in the vehicle-mounted server, the flight control system is used to control the flight system to perform aerial surveying and inspection tasks and receive return data, and the surveying and mapping operation system is used to process the returned image data and generate surveying and mapping results; The platform further comprises a communication management system connected with the satellite communication system and the vehicle-mounted server respectively, for gain amplification of satellite signals and wireless network coverage for the scene.

[0049] The application provides a surveying and inspecting integrated mobile platform for star chain communication and a control method of the mobile platform.

[0050] Figures 1 to 3 An embodiment of the surveying and inspecting integrated mobile platform for star chain communication provided by the application is shown in a structural schematic diagram as Figures 1 to 3 The surveying and inspecting integrated mobile platform for star chain communication takes a mobile carrier 101 as a carrier, and integrates a satellite communication system 102, a power system 103, a flight system 104, a vehicle-mounted server 105, a flight control system 106 and a surveying and mapping operation system 107. The satellite communication system 102 adopts a star chain satellite communication device, and is used for providing the whole platform with internet access. The power system 103 includes an outdoor mobile power supply 201, a gasoline generator 202 and an external power supply interface 203, and is configured with a power management unit 204, which is used for realizing automatic switching and management between multiple power supplies, wherein the outdoor mobile power supply is configured as a main power source of the system. The flight system 104 is an integrated unmanned aerial vehicle platform arranged on the mobile carrier 101. The flight control system 106 and the surveying and mapping operation system 107 are installed in the vehicle-mounted server 105, the flight control system 106 is used for controlling the flight system 104 to perform a surveying and inspecting task and receiving returned data, and the surveying and mapping operation system 107 is used for processing the returned image data and generating surveying and mapping results. The platform further includes a communication management system 108 connected with the satellite communication system 102 and the vehicle-mounted server 105 respectively, which is used for gain amplifying satellite signals and providing wireless network coverage on site.

[0051] The mobile carrier 101 can be, but is not limited to, a pickup truck, a van, an SUV and the like, and can also be other customized platforms with sufficient carrying capacity and moving ability.

[0052] Specifically, the surveying and inspecting integrated mobile platform for star chain communication is realized by constructing a highly integrated autonomous operation system on the mobile carrier 101.

[0053] The system first integrates a satellite communication system based on star chain technology, which is used as the only reliable means for the platform to obtain internet access in an area without ground network coverage.

[0054] The power system 103 adopts a composite power supply architecture, taking an outdoor mobile power supply as the main power source, and being equipped with a gasoline generator and an external power supply interface as a supplement and emergency power source.

[0055] It should be noted that the embodiment is also configured with a dedicated power management unit 204, which can automatically monitor the power state and perform switching operations according to a preset strategy.

[0056] For example, in a typical operation scenario, the system defaults to using the energy storage power supply; when it is monitored that the power is less than 30% and there is available mains power on site, it is automatically switched to the external power supply 201 and charges the energy storage power supply; if the power is further reduced to 20% and there is no external power supply, the gasoline generator 202 is started; in the extreme case, such as when the power is less than 10% and the generator cannot be used, the power generation device of the vehicle itself is enabled for minimum emergency power supply, thereby forming a hierarchical solution to ensure the continuity of power supply.

[0057] At the flight operation level, the mobile platform of the embodiment is equipped with an integrated unmanned aerial vehicle platform as the flight system 104, and is equipped with a vehicle-mounted server 105. The server is simultaneously installed with a flight control system 106 and a surveying and mapping operation system 107, and the two systems realize task cooperation through a software interface.

[0058] The specific workflow is: the flight control system 106 plans and controls the unmanned aerial vehicle to perform a preset route inspection task, and simultaneously receives the telemetry data and video stream returned by the unmanned aerial vehicle; after the task is completed, the flight control system 106 automatically pushes the original image data to the surveying and mapping operation system 107, which performs real-time analysis and generates orthographic images or three-dimensional models and other directly usable surveying and mapping results. This way realizes the localization and automation of the whole process from data acquisition to result generation.

[0059] It is worth mentioning that the mobile platform of the embodiment also integrates a communication management system 108, which is responsible for receiving Starlink satellite signals and performing gain processing on the signals through a built-in signal amplification device, effectively expanding the coverage range of the wireless network.

[0060] At the same time, the communication management system 108 has network traffic control capability, can perform double identity verification based on user accounts and MAC addresses, and allocate differentiated network bandwidth for different priority services. For example, the system can guarantee that the flight system data return enjoys a dedicated uplink bandwidth of not less than 50Mbps, and sets a daily traffic quota of 5GB for ordinary project management accounts, and automatically limits the speed to 1Mbps when the quota is exceeded, so as to ensure that the data transmission of the core inspection business is not disturbed.

[0061] The communication management system 108 establishes a stable dual-link network topology by establishing a wired link to the vehicle server 105 and a wireless coverage link provided by the signal amplification device, providing parallel network access capabilities for high-performance computing devices within the platform and mobile terminals of on-site personnel.

[0062] In this embodiment, Starlink satellite communication, a hybrid propulsion system, an automated UAV airport, a mobile computing center, and a communication management system are integrated onto a single mobile vehicle. Through deep integration and collaborative operation of these subsystems, a complete mobile operation unit independent of local infrastructure is constructed. Starlink solves the network access problem in remote areas, a multi-power automatic switching strategy ensures continuous power supply, and fully automates the entire process of UAV aerial survey and inspection data collection, wireless transmission, on-site processing, and results publication. This approach effectively solves the three core problems that have long existed in remote project sites: communication interruptions, unstable power supply, and long data processing cycles. It compresses and integrates the traditional field operation process, which requires multiple independent links, multi-party personnel cooperation, and heavy reliance on back-end support, into a highly efficient closed loop that can independently complete the entire chain of "communication-power supply-flight-data processing" on-site, significantly improving the overall efficiency and timeliness of aerial survey and inspection operations.

[0063] In some embodiments of the present invention, the power system 103 further includes a self-generating device for the mobile vehicle, and the power management unit 204 integrates an automatic switching switch and executes the following power supply strategy: Outdoor portable power banks should be used as the preferred power source. When the power of the outdoor power bank is lower than the first preset threshold and an external power source is detected, it automatically switches to the external power source and charges the outdoor power bank at the same time. When the power of the outdoor portable power bank is lower than the second preset threshold and no external power source is detected, the gasoline generator will be automatically started to provide power and charge the outdoor portable power bank. When the power of the outdoor portable power source is below the third preset threshold, and there is no external power supply and the gasoline generator is unavailable, the self-generating device of the mobile vehicle will be activated for emergency power supply.

[0064] Based on the composite power architecture, this embodiment further achieves multiple guarantees of power supply by introducing a self-generating device for mobile vehicles and setting a refined power supply strategy.

[0065] The automatic transfer switch integrated in the power management unit is the core component for implementing this strategy, and it follows a clear priority and condition triggering mechanism.

[0066] As a preferred embodiment, the first preset threshold, the second preset threshold, and the third preset threshold are set to 30%, 20%, and 10%, respectively.

[0067] It should be noted that the first, second, and third preset thresholds mentioned above are set according to actual application needs and should not be construed as specific restrictions.

[0068] Specifically, under normal circumstances, the system prioritizes the use of a clean and low-noise outdoor portable power bank 201 for power supply. When the power management unit 204 detects that the power level has dropped to a first preset threshold (e.g., 30%) via a voltage sensor, if an external power source (such as mains power) is simultaneously detected, the automatic switching switch will switch the main power supply line to the external power source within 0.5 seconds and simultaneously start the charging circuit to replenish the outdoor portable power bank with a limited current (e.g., 10A) until the power level recovers to a higher level (e.g., 80%), after which it will automatically switch back to the portable power bank power supply mode. If the power level continues to deplete to a lower second preset threshold (e.g., 20%) and no external power source is detected, the system will automatically start the gasoline generator 202, which will directly handle the system load and charge the outdoor portable power bank with an appropriate power (e.g., within 2kW).

[0069] It should be noted that a key addition to this embodiment is the provision of a final emergency backup: when the power supply drops to a third preset threshold (e.g., 10%), and both the external power source and the gasoline generator 202 are unavailable, the system will activate the self-generating power unit of the mobile vehicle 101. This unit uses the engine within the mobile vehicle to drive an onboard generator to produce electricity, which, after conversion by an inverter, provides emergency power to maintain basic operation of core equipment such as the communication management system 108 and the onboard server 105.

[0070] The beneficial effect of adopting a tiered power supply method in this embodiment is that by constructing a seamless power system from main power to backup power and then to emergency power, it not only maximizes the use of clean energy storage power, but also effectively extends the continuous operation time of the system through external power and gasoline generators. Finally, by relying on the power generation capacity of the vehicle itself, it provides critical power emergency protection for the system under extreme conditions, thereby ensuring the ultra-high operational reliability and mission continuity of the entire platform in complex power supply environments in remote overseas areas.

[0071] In some embodiments of the present invention, the self-generating device of the mobile vehicle 101 is a low-power emergency power generation device, which drives the generator to output electrical energy through the engine of the mobile vehicle, and then supplies power to the platform equipment after conversion by the inverter.

[0072] Specifically, the raw electrical energy output by the self-generating device of the mobile vehicle is typically the vehicle's standard 12V or 24V DC power. To enable it to power AC electrical equipment on the mobile platform, this embodiment includes an inverter for power conversion.

[0073] For example, the 12V DC power output by the generator driven by the engine is converted into 220V, 50Hz AC power by the inverter before it can provide power to maintain basic operation of key equipment such as the core module of the communication management system and the vehicle server that is in a reduced-frequency operation state.

[0074] Furthermore, in this embodiment, the output power of the self-generating device of the mobile vehicle 101 is strictly limited to a low level, for example, no more than 1 kilowatt. This positioning ensures that the core functions of the system can only be maintained under extreme conditions, rather than driving the entire equipment load.

[0075] Preferably, the outdoor portable power supply 201 is arranged on a pull-out slide rail inside the mobile vehicle 101 and is equipped with a positioning pin for convenient centralized charging. The combination of the pull-out slide rail and positioning pin optimizes the spatial layout and maintainability of the power supply unit.

[0076] In practice, the power supply unit is installed on a pre-set slide rail mechanism inside the cargo box. The slide rail has sufficient load-bearing capacity and pull-out stroke. A positioning pin hole is provided in the fully extended position of the slide rail. By inserting the positioning pin, the power supply unit can be stably positioned.

[0077] This approach ensures the stability of the power supply during transportation and provides a convenient operating space for centralized on-site charging operations, significantly improving the maintainability and operational efficiency of the equipment.

[0078] The beneficial effect of this embodiment lies in clearly defining the low-power and emergency attributes of the self-generating device and integrating it with the vehicle's power system, thus constructing the ultimate power guarantee for the entire platform. This method effectively utilizes the inherent power resources of the vehicle, eliminating the need to carry additional fuel. In extreme situations such as gasoline generator failure or fuel exhaustion, it can prevent the entire system from being completely paralyzed due to a complete power outage, providing crucial power support for emergency communication and data preservation of core equipment, thereby greatly improving the system's survivability and mission reliability in complex and harsh environments.

[0079] In some embodiments of the present invention, the outdoor mobile power supply 201 is connected in parallel in multiple groups to add up the total energy storage capacity.

[0080] Specifically, this implementation integrates multiple independent outdoor portable power units through a parallel circuit. For example, six sets of outdoor portable power units with a nominal capacity of 2 kWh can be connected in parallel. In parallel mode, the positive terminals of each power unit are connected to positive terminals and the negative terminals to negative terminals, so that the output voltage of the entire power system is maintained at the same level as a single power unit (e.g., 220V), while the total output current and total energy storage capacity are algebraically added together. In this example, the total system capacity can reach 12 kWh. This configuration ensures that its output voltage is fully matched with the rated input voltage of various electrical devices on the platform, eliminating the need for additional voltage conversion equipment, and can support the entire system to work continuously for more than 8 hours, meeting the needs of long-term field operations in overseas projects. In addition, this modular parallel method usually facilitates the isolation and replacement of individual faulty units, improving the maintainability of the system.

[0081] This embodiment employs a stable and reliable electrical connection method to effectively enhance the energy reserves of the mobile platform while ensuring a constant output voltage. Simultaneously, this method directly extends the system's continuous operating time without external power replenishment, reduces reliance on on-site infrastructure, enhances the platform's operational flexibility and endurance in remote areas, and provides ample energy support for continuously completing large-scale aerial survey and inspection missions.

[0082] In some embodiments of the present invention, the communication management system 108 includes a signal amplification device 301 and a traffic control device 302; The signal amplification device 301 is connected to the satellite communication system 102 and is used to increase the power of the network signal output by the Starlink router. The traffic control device 302 is connected to the signal amplification device 301 and the vehicle server 105 respectively, and is used to allocate differentiated network bandwidth to different users and / or devices based on identity information, and to guarantee bandwidth for the data backhaul service of the flight system 104.

[0083] In this embodiment, the internal structure of the communication management system 108 integrates two core components, a signal amplification device 301 and a traffic control device 302, to achieve optimized management and intelligent allocation of satellite network signals.

[0084] The signal amplification device 301 is directly connected to the Starlink router of the satellite communication system 102. Its main function is to perform power gain processing on the original network signal output by the router, effectively compensate for the signal attenuation during transmission, and expand the coverage of the wireless network.

[0085] The traffic control device 302 plays an intelligent scheduling role in the network. It is connected to the signal amplification device 301 and the vehicle server 105 via wired connections to form a complete data path. The device implements differentiated management of network resources based on the identity information composed of user accounts and MAC addresses.

[0086] Specifically, the traffic control device 302 allocates an independent guaranteed bandwidth channel for the data backhaul service of the flight system 104 to ensure its transmission priority; at the same time, it sets traffic usage limits for ordinary user equipment and automatically implements a rate limiting policy after the limit is reached.

[0087] For example, in a typical application scenario, the system can guarantee a dedicated uplink bandwidth of 50Mbps for drone data backhaul, while setting a daily traffic quota of 5GB for ordinary project management accounts, and automatically limiting the rate to below 1Mbps after exceeding the limit.

[0088] This embodiment, through the coordinated operation of two devices, ensures both the reliability of critical business data transmission and the rational allocation of network resources. The signal amplification device 301 solves the problem of insufficient Starlink signal coverage in complex environments, while the traffic control device, through a refined bandwidth management mechanism, effectively avoids situations where non-critical services consume large amounts of bandwidth, thus affecting core inspection tasks. This significantly improves the overall system's performance and mission reliability in bandwidth-constrained satellite network environments.

[0089] In some embodiments of the present invention, the traffic control device 302 ensures that the uplink bandwidth for the data backhaul service of the flight system 104 is not lower than a fourth preset threshold; and sets traffic usage limits for non-priority users and / or devices, and implements network access restrictions after the limits are exceeded.

[0090] Specifically, the embodiment uses a traffic control device 302 to control the traffic usage of non-priority users and devices.

[0091] Specifically, the traffic control device 302 sets periodic traffic usage limits for these terminals. When actual usage exceeds the preset limit, network access restriction measures are automatically triggered. For example, a daily traffic quota of 5GB can be set for the mobile terminals of on-site staff. After exceeding this limit, their network access speed is limited to within 1Mbps. This restriction ensures basic network connectivity while effectively preventing non-critical services (such as video streaming and large file downloads) from excessively consuming valuable satellite network bandwidth.

[0092] In this embodiment, by combining bandwidth guarantees and traffic limits, refined management of satellite network resources is achieved. This not only ensures the data transmission quality of the core business of aerial surveying and inspection, but also maintains the fairness of network usage through reasonable usage constraints. Overall, it optimizes the utilization efficiency of limited satellite bandwidth and provides a reliable network environment guarantee for the smooth execution of critical services.

[0093] In some embodiments of the present invention, the communication management system 108 connects its internal signal amplification device 301, so that the network from the Starlink router is converted into a wireless signal for coverage after passing through the signal amplification device 301, forming a wireless network access. A wired link is established between the communication management system 108 and the vehicle server 105; The wired link and wireless network access together form a dual-link network topology that provides wired access for the vehicle server 105 and wireless coverage for the field terminals.

[0094] Specifically, the communication management system 108 in this embodiment adopts a specific network topology to optimize the network access method. By connecting the signal amplification device 301 inside the communication management system 108 to the network link, a clear signal processing path is formed: the wired network signal from the Starlink router first enters the communication management system 108, is then guided to the signal amplification device 301 for power gain processing, and is finally converted into a wireless signal for radiation coverage, thereby establishing a wireless network access for mobile terminals.

[0095] Meanwhile, the communication management system 108 establishes a direct wired link with the vehicle-mounted server 105 through an independent wired network interface. This wired link, together with the aforementioned wireless network access, constitutes a parallel dual-link network topology. Under this structure, the vehicle-mounted server 105, as the core computing unit, obtains a stable and reliable high-speed connection through a dedicated wired link; while the mobile terminal devices of the field operators access system resources through wireless network access.

[0096] This embodiment achieves rational allocation and isolation of network resources through the separation of wired and wireless links. The wired links provide deterministic network assurance for data processing tasks requiring high bandwidth and low latency, avoiding interference from wireless signal fluctuations on core computing tasks; the wireless network provides necessary access flexibility for mobile on-site work. Simultaneously, this dual-topology structure not only improves the overall reliability of the network system but also effectively reduces mutual interference between different types of services through physical-level channel isolation, thereby optimizing the network communication performance of the entire system.

[0097] In some embodiments of the present invention, the flight system 104 is fixed inside the cargo box of the mobile vehicle by a customized bracket. A shock-absorbing pad is provided between the bracket and the cargo box bottom plate, and it is fixed to the cargo box longitudinal beam by expansion bolts. Foldable diagonal braces are provided between the two sides of the bracket and the cargo box side panels to enhance wind resistance stability during operation.

[0098] In this embodiment, a custom-made bracket is used as the core load-bearing structure for the fixing mechanism. The bracket is firmly connected to the cargo box floor and longitudinal beams in a specific way.

[0099] Specifically, an elastic shock-absorbing pad is installed between the bottom of the support frame and the contact surface of the cargo box floor. This shock-absorbing pad is made of silicone material with a specific hardness, which can effectively absorb the vibration energy generated during vehicle operation. The main body of the support frame is directly and securely connected to the load-bearing longitudinal beams at the bottom of the cargo box by multiple expansion bolts, ensuring the reliability of the connection.

[0100] Preferably, the antenna of the satellite communication system 102 is mounted on the top of the mobile vehicle via a foldable bracket, which is configured to allow the antenna to have a folded storage state corresponding to the movement of the mobile vehicle, and an unfolded and locked working state corresponding to platform operation.

[0101] It should be noted that, to further enhance the system's stability during operation, a foldable diagonal bracing mechanism has been added between the support frame and the cargo box side panels on both sides. This diagonal bracing uses a tubular structure and is folded in the transport state. When the platform enters the operational state, it can be quickly unfolded and securely connected to the side panels via a snap-fit ​​mechanism, forming a stable triangular structure. For example, when facing lateral wind loads common in overseas regions, this structure can effectively resist the effects of winds below level 8, preventing the flight system 104 from overturning during takeoff and landing.

[0102] Preferably, the flight system 104 has a built-in emergency decision module that automatically executes a preset return-to-home or emergency landing procedure when the network latency with the flight control system 106 exceeds 100ms or the disconnection exceeds 3 seconds.

[0103] It should be understood that the emergency decision-making module built into the flight system 104 provides it with critical autonomous safety capabilities. This module continuously monitors the communication status with the ground flight control system 106, and automatically triggers preset safety strategies when a network latency exceeds 100 milliseconds or a complete communication interruption lasts for 3 seconds, such as automatically returning to the takeoff point or finding a safe area for an emergency landing.

[0104] The beneficial effect of this implementation method is that it provides mobile platforms with emergency response capabilities independent of human intervention in field environments where satellite links are unstable, effectively reducing the risk of drone loss or crash due to communication interruption, and significantly improving the safety and mission reliability of the operating system.

[0105] This embodiment, through the synergistic effect of shock absorption, fastening, and windproof triple structural measures, ensures both the safety and integrity of the flight system during transportation and its stability and reliability during operation. It provides the necessary mechanical support for the normal operation of the flight system under special conditions, thereby improving the adaptability of the entire platform in complex field environments and the mission success rate.

[0106] In one embodiment of the present invention, the real-time flight data transmitted back by the flight system 104 includes three key data types: remote control commands from the control terminal, device status telemetry data reflecting the state of the UAV itself (including information such as position, attitude, and battery level), and adaptive bitrate video streams that have been efficiently encoded and compressed using H.265.

[0107] This video stream can dynamically switch between 1080p high-definition bitrate and 720p standard-definition bitrate based on real-time bandwidth fluctuations in the Starlink satellite network. For example, when bandwidth is sufficient, high-definition images are transmitted to obtain more details, while when bandwidth is tight, it automatically reduces to standard-definition mode to ensure transmission continuity.

[0108] The flight control system 106 and the mapping and computing system achieve automated data interaction through a custom-developed software interface (API). The specific workflow is as follows: after the flight system completes the preset aerial survey and inspection task, the flight control system automatically calls and starts the mapping and computing system through the API interface, and hands over the returned raw image data to the latter for processing.

[0109] In a specific implementation, the flight control system can be the DJI Sky2 system, the mapping and computing system can be the DJI Terra system, and the flight system can be the DJI Airport 3 integrated drone platform. The three can form a collaborative whole through the aforementioned methods.

[0110] This embodiment ensures reliable transmission of critical video data under fluctuating network conditions through an adaptive bitrate transmission mechanism. At the same time, it achieves seamless connection from data acquisition to processing by using automated interfaces between systems, significantly reducing manual intervention and improving the overall efficiency and intelligence level of on-site operations.

[0111] Figure 4 and Figure 5 This is a flowchart illustrating an embodiment of the mobile platform control method provided by the present invention. This mobile platform control method is applied to the aforementioned Starlink communication integrated aerial survey and inspection mobile platform.Figure 4 and Figure 5 As shown, the mobile platform control method includes power supply control steps executed by the power management unit and communication management steps executed by the communication management system.

[0112] The power supply control steps include: S401. Prioritize using outdoor mobile power supplies to power the system, and monitor the power level of the outdoor mobile power supply and the connection status of external power sources and gasoline generators in real time. S402: When the power of the outdoor power bank is lower than the first threshold and an external power source is available, switch to the external power source for power supply and charge the outdoor power bank. S403. When the power of the outdoor portable power supply is lower than the second threshold and there is no external power source, start the gasoline generator to provide power and charge the outdoor portable power supply. S404. When the power of the outdoor mobile power source is below the third threshold, and there is no external power source connected, and the gasoline generator is unavailable, the self-generating device of the mobile vehicle shall be activated for emergency power supply.

[0113] Specifically, the power supply control steps in this embodiment achieve continuous power supply for the system through a hierarchical decision-making mechanism.

[0114] Step S401 establishes the outdoor mobile power supply as the priority power supply unit, while continuously monitoring its remaining power and the access status of each backup power supply.

[0115] When step S402 is executed, if the power of the mobile power bank is detected to be lower than the first threshold (e.g., 30%) and an external power source is detected, the system will switch the power supply load to the external power source and simultaneously start the process of charging the mobile power bank with a limited current (e.g., 10A).

[0116] Step S403 specifies that when the battery level drops further to a second threshold (e.g., 20%) and no external power source is available, the gasoline generator is automatically started as the main power source, and it is controlled to charge the mobile power source at an appropriate power (e.g., 2kW).

[0117] As an emergency backup, step S404 involves activating the self-generating power unit of the mobile vehicle when the power level drops to the third threshold (e.g., 10%) and the first two backup power supplies cannot be activated. This unit outputs electrical energy through the vehicle engine, which is converted by an inverter, to provide power for the communication management system, the on-board server operating at reduced frequency, and other core equipment to maintain basic operation.

[0118] The beneficial effect of this power supply control procedure is that, by setting multiple threshold trigger conditions and sequential switching logic, a seamless power supply system is constructed, connecting the main power source to backup power and then to emergency power. This not only ensures the continuity of energy supply but also extends the system's continuous operating time through intelligent charging management. Ultimately, it leverages the vehicle's self-generating capacity to achieve power assurance under extreme operating conditions, significantly improving the platform's power supply capability in remote areas.

[0119] The communication management steps include: It receives and amplifies Starlink satellite signals; and executes a differentiated network resource allocation strategy based on identification information, including: S501, allocate guaranteed bandwidth for the data backhaul service of the flight system; S502. Set traffic usage limits for non-priority users and / or devices, and implement network access restrictions after the limits are exceeded.

[0120] Specifically, efficient utilization of satellite networks is achieved through coordinated operations at both the signal processing and resource scheduling levels.

[0121] First, the physical layer reception and gain amplification of Starlink satellite signals are completed. Then, at the network management layer, a differentiated resource allocation strategy is implemented based on user account and MAC address identification information. The specific implementation of this strategy includes two key operations: Step S501 establishes an independent bandwidth guarantee channel for the flight system's data backhaul service, for example, allocating a dedicated uplink bandwidth of no less than 50Mbps to ensure stable transmission of flight survey data; Step S502 implements usage control for non-priority users and equipment by setting periodic traffic limits (such as a daily quota of 5GB) and over-limit handling mechanisms (such as limiting the rate to 1Mbps after exceeding the limit), effectively constraining the network resource occupation of non-critical services.

[0122] This embodiment combines signal enhancement technology with intelligent resource allocation strategies to improve network coverage quality while achieving refined management of bandwidth resources, ensuring communication quality for core services such as aerial surveying and inspection, and maintaining fair allocation of network resources through usage limitation mechanisms, thereby maximizing system communication efficiency in the limited bandwidth environment of satellite links.
