[0027] See also Figure 1 , a ground receiving system for an operation identification signal, comprising a broadcast signal transceiver module 2, a ground station signal processing unit 3, and a network signal transceiver module 4. The broadcast signal transceiver module 2 is used to receive the operation identification information sent by the UAV in the airspace through an antenna; the ground station signal processing unit 3 is connected to the broadcast signal transceiver module 2, receives and processes the UAV identification information from the broadcast signal transceiver module 2; the network signal transceiver module 4 is connected to the ground station signal processing unit 3, sends a wireless network signal through an antenna, connects to a cloud server 5, and is used to wirelessly transmit the processed identification information to the cloud server 5, which then distributes it to users who provide operation identification services.

[0028] Preferably, the ground station signal processing unit 3 is connected to the cloud server 5 via a wired connection, and the cloud server 5 distributes the information to users who provide operation identification services.

[0029] In this embodiment, the system can monitor drone operational identification signals in real time, independent of the drone. Data can be transmitted to a cloud server via both network-based signal transmission and reception and wired network communication. The cloud server then transmits the data wirelessly to the user end providing the operational identification service. This data is then uploaded to the user end providing the operational identification service, enabling the user to monitor the drone's flight status in real time. Tamper-resistant encryption methods, such as identity recognition, key authentication, and device behavior locking within IoT security, are used to transmit drone status information to the user. This ensures effective drone monitoring and identification while protecting the privacy of the drone and its operator. This reduces the possibility of operational identification signals being tampered with or forged, ensuring the authenticity of the drone's operational identification signals during generation, transmission, reception, and management, effectively mitigating network security risks.

[0030] In one embodiment, the operation identification signal includes: identification code data and flight dynamics data; the identification code data includes unique independent UAV operation identification system code data and registration authority code data; the flight dynamics data includes timestamp, UAV real-time flight position and motion status data.

[0031] In this embodiment, the motion status data includes the accumulated flight time, flight speed, track and operation status of the UAV.

[0032] It should be noted that the real-time drone flight location is the current spatial location of the drone. The returned data includes the coordinate system type, latitude and longitude, altitude, and height, all of which default to national standards. The receiving platform uses the drone's horizontal and vertical speed data to predict the drone's flight trajectory and operational risks. The accuracy of the drone's reported information and its operating status can be used to analyze whether the aircraft is currently operating normally or in an emergency, such as a loss of control.

[0033] In one embodiment, the operation identification signal further includes: remote control identification data; the remote control identification data is derived from data collected by the identification data generation module, including the location of the remote control station and flight destination indication data.

During the access process, the visitor's management and / or access rights are verified, and only those with management and / or access rights are allowed to access the operational identification signal. The public and management parties can digitally receive basic information about drones, enabling organized management of drone operations and ensuring airspace safety.

[0036] Furthermore, when the identification data transmission module sends the identification data through the cellular network, other users can access it through the remote identification ID, but the identity recognition function will deny access to the public without management authority and only allow administrators to have access rights.

[0037] In one embodiment, the key authentication steps include:

[0038] When the identification data transmission module is connected to the Internet of Things: obtain the key issued by the Internet of Things platform to perform identity authentication of the independent drone operation identification system, adopt a one-machine-one-key method, burn the system certificate and store it, ensuring the privacy protection of the drone and the operator.

[0039] During the wireless broadcast and wireless transmission process of the identification data transmission module: the system certificate is used for identity authentication, and the key is used to encrypt the operation identification signal of the wireless broadcast and wireless transmission.

[0040] In one embodiment, the device behavior recognition actions include:

[0041] Based on the historical operation identification signals of drones, suspicious behaviors are judged and rejected according to the set rules to ensure the safety of drone flights, prevent the execution of malicious commands, and improve the safety and reliability of drone flights.

[0042] Preferably, the broadcast signal transceiver module 2 includes: a classic Bluetooth module, a low-power Bluetooth module and a WIFI module.

[0043] Preferably, the WIFI module includes a WIFI module configured in NAN mode and a WIFI module configured in Wi-Fi Beacon scanning mode, and the high-frequency Bluetooth module includes a high-frequency Bluetooth module configured in BLE5.0 mode and a high-frequency Bluetooth module configured in Legacy mode.

[0044] In a specific embodiment, two WIFI modules and two high-frequency Bluetooth modules are configured. One WIFI module is configured in NAN mode to receive operation identification signals broadcast via WIFI NAN, and one WIFI module is configured in Wi-Fi Beacon scanning mode to receive operation identification signals broadcast via WIFI Beacon. One high-frequency Bluetooth module is configured in BLE 5.0 mode to receive operation identification signals broadcast via Bluetooth BLE 5.0 extension, and one high-frequency Bluetooth module is configured in Legacy mode to receive operation identification signals broadcast via Bluetooth Legacy.

[0045] Preferably, the ground station signal processing unit 3 includes a computing chip main control ARM (ARM) and a memory module. The computing chip main control ARM in the ground station signal processing unit 3, which supports the IoT protocol, analyzes and packages the drone's operational identification signals. The broadcast signal transceiver module 2 collects the drone's operational identification signals within the airspace and transmits them to the main control chip ARM for subsequent data transmission.

[0046] Preferably, the network signal transceiver module 4 includes a 4G communication module and a 5G communication module.

[0047] Preferably, the antenna includes a built-in antenna and / or an external antenna, and the external antenna is connected to an external interface on the identification signal ground receiving system.

[0048] In an application scenario, the antenna includes a first antenna 6 and a second antenna 7 , the first antenna 6 is connected to the broadcast signal transceiver module 2 , and the second antenna 7 is connected to the network signal transceiver module 4 .

[0051] Through the above design, the system's signal quality, flexibility, user experience and overall performance can be significantly improved, providing users with more efficient and reliable drone operation and data transmission solutions.

[0052] It should be noted that switching between the internal and external antennas utilizes existing automatic detection and control technology. An electrical detection circuit monitors the external antenna's connection status in real time, and a microcontroller switches the signal path, ensuring flexible and stable signal reception. The system also offers a manual switching option to meet diverse user needs. This technology is widely used in mobile communication devices, so the specific switching circuitry and control methods will not be described in detail here.
