Abstract
Description
Technical Field
[0001] This invention relates to the field of spectrum monitoring, particularly to the field of radio spectrum, specifically to a method, system, device, processor, and computer-readable storage medium for achieving real-time spectrum monitoring based on a drone nest and a fixed monitoring station. Background Technology
[0002] Radio spectrum is a finite, reusable natural resource, and also a valuable strategic resource. To ensure the normal operation of various wireless devices and prevent mutual interference, radio management departments need to conduct daily monitoring of the radio spectrum, understand the transmission of radio signals within the region, and promptly investigate and punish illegal radio applications.
[0003] Fixed monitoring stations are the main technical facilities for spectrum monitoring, primarily consisting of monitoring receivers, direction-finding receivers, feeders, antennas, industrial control computers, and display terminals. They can continuously monitor the radio spectrum in the surrounding area and determine the direction of arrival of target signals through direction-finding equipment, thus assisting in interference detection.
[0004] With the advancement of drone technology, the use of drones to carry radio monitoring and direction finding equipment for spectrum monitoring has also seen significant development in recent years. It can overcome the obstruction and reflection of ground buildings, which is beneficial for signal reception and can achieve excellent results in certain specific situations.
[0005] Full-time spectrum monitoring refers to an automated and intelligent monitoring method that continuously acquires regional spectrum signals over a relatively long period of time (7×24 hours), analyzes and locates unknown signals in the spectrum, and issues alarms for illegal signals.
[0006] Fixed monitoring stations are well-equipped and ideally located, enabling long-term monitoring of radio signals in the surrounding area. However, they also have the following problems: 1. The investment in site management is relatively large, so the number of sites will not be too many. They are generally located in the core areas of the city and cannot achieve full coverage.
[0007] 2. As cities continue to develop, the surrounding environment of existing stations is changing rapidly, with tall buildings emerging one after another, causing varying degrees of impact on signal reception.
[0008] 3. The stations are generally far apart, and except for a few low-frequency signals, it is impossible to complete cross-regional collaborative measurements and joint positioning.
[0009] Drone spectrum monitoring also has its own shortcomings: 1. Operating drones requires professional pilots and has high technical requirements, making it impossible to deploy them in large quantities.
[0010] 2. Conventional drones rely on lithium batteries for power, which limits their flight time and cannot meet the requirements for long-term monitoring.
[0011] In summary, existing technologies cannot meet the technical requirements for full-time spectrum monitoring. Summary of the Invention

[0016] Preferably, the measurement parameters in step (3.2) include the center frequency, bandwidth, modulation mode, direction of arrival, appearance time, disappearance time, and matching results with the known signal library.
[0017] Preferably, step (5) specifically includes the following steps: At set time intervals, fixed monitoring stations transmit data from the unknown signal database to the UAV nest. The UAV nest then sends the data from the unknown signal database to the compact monitoring and direction-finding device on the UAV platform, generating a direction-finding task list based on the signal parameters of the unknown signal database.
[0018] Preferably, the minimum time interval in step (5) is the total time required for the UAV to take off, execute the predetermined flight path, return, and automatically recharge.
[0019] Preferably, step (6) specifically includes the following steps: (6.1) The UAV starts up and leaves the UAV nest to take off.

(6.2) The UAV travels along the preset trajectory and the flight trajectory is adjusted according to the actual situation.
[0020] This system, which enables real-time spectrum monitoring based on UAVs in a nest and fixed monitoring stations, is characterized in that the system includes fixed monitoring stations and a UAV monitoring system in a nest. The aforementioned UAV nest monitoring system includes a UAV platform, a compact monitoring and direction-finding system, and a UAV nest. The drone nest is placed in an open area near the fixed monitoring station, connected to the network and power supply system of the fixed monitoring station, and connected to the network module via a network cable. The compact monitoring and direction finding system is installed on the drone platform, connected to the drone's power supply, and wirelessly connected to the drone nest.
[0021] Preferably, the fixed monitoring station includes a control terminal, a network and power supply system, a monitoring receiver and its antenna feed system, and a direction-finding receiver and its antenna feed system.

[0025] This invention employs a method, system, device, processor, and computer-readable storage medium for real-time spectrum monitoring based on a drone nest and a fixed monitoring station. A single fixed monitoring station can only measure the direction of incoming waves and cannot achieve area positioning. However, by using the drone's multi-point direction-finding results along its entire trajectory, combined with signal level distribution and the fixed station's direction-finding results, reliable positioning results can be provided. High-frequency signals have high attenuation and weak diffraction ability, making them difficult to detect by fixed monitoring stations in dense urban environments. Drones, after takeoff, encounter almost no obstructions and have a high probability of approaching surrounding signal sources along their predetermined trajectory, thus making it easier to capture weak high-frequency signals. Compared to the high investment required for fixed monitoring stations, the drone nest monitoring system offers better cost-effectiveness. Through pre-planned trajectory, it can operate normally even in environments where control signals are interfered with, requiring no human intervention. Usage and maintenance costs are controllable, significantly improving utilization compared to traditional drone monitoring. The entire monitoring process is automated, requiring no manual intervention in equipment and software, only confirmation after testing. Furthermore, the collaborative work of the two systems enables the collection of all signal information, making management more scientific and accurate. Attached Figure Description

[0033] Specifically, step (5) includes the following steps: At set time intervals, fixed monitoring stations transmit data from the unknown signal database to the UAV nest. The UAV nest then sends the data from the unknown signal database to the compact monitoring and direction-finding device on the UAV platform, generating a direction-finding task list based on the signal parameters of the unknown signal database.

[0035] Specifically, step (6) includes the following steps: (6.1) The UAV starts up and leaves the UAV nest to take off.

(6.2) The UAV travels along the preset trajectory and the flight trajectory is adjusted according to the actual situation.
[0036] The system for real-time spectrum monitoring based on UAV nests and fixed monitoring stations of the present invention is characterized in that the system includes a fixed monitoring station and a UAV nest monitoring system. The aforementioned UAV nest monitoring system includes a UAV platform, a compact monitoring and direction-finding system, and a UAV nest. The drone nest is placed in an open area near the fixed monitoring station, connected to the network and power supply system of the fixed monitoring station, and connected to the network module via a network cable. The compact monitoring and direction finding system is installed on the drone platform, connected to the drone's power supply, and wirelessly connected to the drone nest.
[0037] The fixed monitoring station includes a control terminal, a network and power supply system, a monitoring receiver and its antenna feed system, and a direction-finding receiver and its antenna feed system. The network and power supply system is connected to the UAV nest of the UAV monitoring system. The control terminal is connected to the network and power supply system. The monitoring receiver and its antenna feed system are connected to the network and power supply system. The direction-finding receiver and its antenna feed system are also connected.
[0038] The system for all-weather spectrum monitoring based on a drone nest and a fixed monitoring station, as described in this invention, is characterized in that the system comprises: A processor is configured to execute computer-executable instructions; The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the various steps of the above-described method for achieving all-time spectrum monitoring based on a nested UAV and a fixed monitoring station.
[0039] The processor of the present invention for realizing all-time spectrum monitoring based on a nested UAV and a fixed monitoring station is characterized in that the processor is configured to execute computer-executable instructions, and when the computer-executable instructions are executed by the processor, the various steps of the above-mentioned method for realizing all-time spectrum monitoring based on a nested UAV and a fixed monitoring station are implemented.
[0040] The main feature of the computer-readable storage medium of the present invention is that it stores a computer program thereon, which can be executed by a processor to implement the various steps of the above-described method for achieving all-time spectrum monitoring based on a nested UAV and a fixed monitoring station.
[0041] In a specific embodiment of the present invention, the monitoring system consists of the following components: Figure 1 As shown, the system comprises two parts: a fixed monitoring station and a UAV monitoring system housed within a drone nest. The fixed monitoring station includes a monitoring receiver and antenna feed system, a direction-finding receiver and antenna feed system, a control terminal, a network, and a power supply system. The UAV monitoring system housed a UAV platform, a compact monitoring and direction-finding system, and a UAV nest. The UAV nest is located in an open area near the monitoring station's equipment room, powered by the fixed monitoring station's power supply system, and connected to the site's switch via a network cable. The compact monitoring and direction-finding system is installed on the UAV platform, powered by the UAV's power supply, and can achieve wireless connectivity via the nest's network hotspot to receive mission information and transmit data back. Figure 1 In the middle, the module above the power supply system is the network module, which is responsible for network data transmission, also known as the site switch.
[0042] Based on the above system, the implementation steps for full-time spectrum monitoring are as follows: 1. Based on the needs of radio management, formulate monitoring tasks and send full-time spectrum monitoring tasks to the monitoring receiver through the control terminal of the fixed monitoring station. The task parameters include the service frequency band to be monitored, execution duration, and abnormal signal alarm methods.
[0043] 2. After receiving the task, the fixed monitoring station receiver automatically starts the panoramic scanning mode according to the task parameters, continuously scans the frequency band of the monitoring target, and transmits the spectrum data back to the control terminal in real time.
[0044] 3. The fixed monitoring station control terminal activates the signal detection function, automatically analyzes and processes the received spectrum data, and extracts the signal frequency through background template or level threshold comparison. Then, it controls the direction-finding receiver to measure the parameters of the extracted signal. The measured parameters include center frequency, bandwidth, modulation scheme, direction of arrival, appearance time, disappearance time, and matching results with a known signal database.
[0045] 4. The fixed station control terminal stores the signal parameters that do not match the known signal library into the unknown signal library and restores the equipment status to the state in step 2. The task is executed cyclically.
[0046] 5. After the set time interval, data from the unknown signal database is transmitted to the UAV's nest via the monitoring station's wired network. The nest then sends the data to the compact monitoring and direction-finding device on the UAV platform via a network hotspot. Based on the signal parameters in the signal database, a direction-finding task list is generated. The minimum time interval is the total time required for the UAV to take off, execute the predetermined flight path, return, and automatically recharge. Considering equipment lifespan and maintenance, the actual cycle should be no less than 12 hours.
[0047] 6. After the mission data is loaded, the UAV starts up, leaves the nest, and takes off. The takeoff altitude is generally no higher than 120 meters. Upon reaching the predetermined altitude, the UAV uses the direction-finding equipment to perform direction-finding tasks according to the mission list, recording measurement results, time, and location information, and storing the data locally. The UAV follows a preset trajectory. A typical trajectory involves the UAV traveling two kilometers in a straight line due north, then circling clockwise before returning. The flight path for different flight durations and speeds can be adjusted according to actual conditions. If there are taller buildings obstructing the path, adjustments will be necessary.
[0048] 7. After the drone returns to the nest, it automatically completes charging and heat dissipation preparation. The compact monitoring and direction finding equipment automatically connects to the nest's wireless network hotspot and transmits the locally stored test data back to the control terminal. After completion, it waits for the next time interval.
[0049] 8. The returned monitoring and direction finding results will be summarized in the unknown signal database, the signal positioning data will be updated, and the signal attribution will be awaited by manual confirmation. After labeling, the signal will be transferred to the known signal database to achieve a closed-loop monitoring system.
[0050] This invention addresses the issues of automation and reliability in the real-time monitoring process, enabling long-term detection, measurement, and location of unknown signals within a specific radio frequency band. Leveraging the powerful monitoring and data analysis capabilities of fixed monitoring stations, combined with the automatic takeoff path planning of a drone monitoring system and the superior direction-finding and positioning effects resulting from unobstructed aerial signals, it achieves automatic identification and measurement of frequency band signals. This solution utilizes the fully automated path planning capabilities of drones combined with drone nests and the improved monitoring and direction-finding quality resulting from integration with fixed stations.
[0051] The core of this invention is frequency resource management in radio monitoring. It combines monitoring equipment carried by drones with monitoring equipment from fixed monitoring stations, leveraging the strengths of each to achieve long-term automatic monitoring. The technical approach involves the fixed station performing spectrum scanning and signal detection, transmitting the measurement results to the drone monitoring system for aerial signal direction finding and positioning, and then summarizing the results to improve the signal database, thus achieving automatic signal management. The two systems still only overlap on the drone itself. This invention does not involve communication between drones and their nests or between drones and base stations. Instead, it considers data transmission within the nest's network hotspot to avoid potential communication interference and instability. The core issue remains the automation of frequency band monitoring.
[0052] This invention relates more to the application of drones, but the core is not the drone itself, but the monitoring system it carries and its coordinated application with fixed station monitoring systems.
