Detailed Implementation

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the invention will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0019] Furthermore, the accompanying drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in one or more hardware units or integrated circuits, or in different processor devices and / or microcontroller devices.

[0020] To address the shortcomings and deficiencies of existing technologies, this example embodiment provides a mobile drone navigation and landing device, which can be used to disassemble and optimize the overall structure of the navigation and landing device, achieving the advantage of easy assembly on mobile devices such as vehicles.

[0021] refer to Figure 1 As shown, the mobile drone navigation and landing device includes a transmitting antenna 101 and a receiving antenna 102 installed outside the vehicle, and a main unit 105 and a storage box 106 installed inside the vehicle. The main unit 105 is connected to both the transmitting antenna 101 and the receiving antenna 102 via radio frequency (RF) cables. For example, a through-hole can be made in the vehicle roof to allow the RF cable to extend from the outside of the vehicle to the inside, facilitating connection to the main unit. The main unit is mounted inside the storage box 106 using fasteners.

[0022] refer to Figure 2 As shown, at least two connecting posts 107 are symmetrically arranged on the top of the storage box 106; each connecting post 107 is provided with a quick-release latch 108 at its top, which is used to cooperate with the quick-release latch slot 111 provided in the vehicle. The storage box can be a hollow box body, which makes it easy to insert the main body into the storage box.

[0023] Specifically, two or four quick-release slots 111 can be symmetrically arranged and fixed to the roof of the vehicle by bolts or welding. Correspondingly, two or four quick-release blocks 108 are symmetrically arranged at the top of the storage box 106, which cooperate with the quick-release slots 111. The quick-release blocks 108 can slide into the slots along the grooves provided on the quick-release slots 111 and be fixed. This enables quick assembly and disassembly of the storage box and the main unit as a whole, facilitating the disassembly, assembly, and routine maintenance of the main unit.

[0024] For example, refer to Figure 2 As shown, a shock-absorbing layer 109 is provided on the inner wall of the storage box 106 to fill the gap between the inner wall of the storage box 106 and the main unit 105. For example, the shock-absorbing layer can be made of materials such as resin or rubber. Considering the actual scenario of a vehicle driving on bumpy roads, by setting up a shock-absorbing layer, the vibration of the main unit in the storage box can be reduced, avoiding equipment failure caused by vibration.

[0025] For example, the bottom surface inside the storage box 106 is also provided with a fixing groove 110 for fixing the main unit housing, which matches the support feet at the bottom of the main unit housing. The bottom of the main unit housing can be provided with fixed support feet, and the support can be a cylinder or an inverted conical structure. The corresponding fixing grooves on the bottom surface inside the storage box 106 can stably mount the main unit inside the storage box housing, reducing the shaking of the main unit during vehicle operation.

[0026] Example, reference Figure 1 As shown, the device also includes an electromagnetic environment scanning component 103 mounted on the roof of the vehicle. The electromagnetic environment scanning component 103 is connected to the host computer 105 via a radio frequency connection cable, enabling communication between the host computer and the upper computer 100. It is used to collect local satellite navigation frequency bands and terrestrial cellular network radio frequency signals and transmit them to the upper computer 100. The satellite navigation frequency bands and terrestrial cellular network radio frequency signals identified by the electromagnetic environment scanning component 103 are displayed on the upper computer.

[0027] For example, the mobile drone navigation and landing device further includes: an optoelectronic / infrared sensor assembly 104 mounted on the roof of the vehicle; the optoelectronic / infrared sensor assembly 104 is connected to the host computer 105 via an radio frequency connection cable, and communicates with the host computer 100 through the host computer. The optoelectronic sensor and the infrared sensor can be a camera or an infrared sensor, used to acquire images of the drone in a designated airspace, and display the acquired image data on the host computer for the user to view.

[0028] For example, refer to Figure 2 As shown, the host 105 includes a housing, a main control unit 200 disposed within the housing, and a power control unit 201, a receiving and time synchronization unit 202, a signal generation unit 203, and a signal transmission control unit 204, all connected to the main control unit 200. The receiving and time synchronization unit 202 is connected to the signal generation unit 203.

[0029] Specifically, the power control unit is connected to the vehicle power supply to provide power to various components. The main control unit 200 can be a central processing unit (CPU) used to receive and process control commands sent from the host computer, generate strategy parameters and workflow instructions based on the parameters carried in the control commands, and send the workflow instructions to the receiving and time synchronization unit 202, the signal generation unit 203, and the signal transmission control unit 204. The workflow instructions indicate the working timing information of the corresponding unit and carry business instructions, indicating the specific business to be executed. Strategy parameters can be parameters such as the desired offset direction and offset distance of the navigation signal. In addition, strategy parameters can also include power variation ranges, planned paths, or position coordinates. Strategy parameters can be carried in the control commands issued by the host computer, and the main control unit obtains the specific parameters after parsing the control commands. Users can define custom strategy parameters on the host computer and send them to the main unit.

[0030] For example, the receiving and time synchronization unit is used to extract core parameters from the navigation information of the satellite navigation system received by the receiving antenna and generate guidance parameters for the descent signal.

[0031] Specifically, the receiving and time synchronization unit 202 includes a first processing unit 302 and a clock unit 301. The first processing unit receives and responds to the workflow instructions of the main control unit 200, executes specific business instructions, and sends instruction information to the clock unit 301, controlling the clock unit 301 to extract high-precision time information based on the received satellite navigation signals and generate a standard time signal based on the high-precision time information. The standard time signal is pushed to the signal generation unit by the first processing unit.

[0032] For example, the signal generation unit can be used to generate GNSS / GPS simulation signals based on standard time signals and strategy parameters. The signal generation unit 203 can be a GNSS signal simulator.

[0033] Specifically, the GNSS signal simulator includes a second processing unit 303, a clock control unit 304, a time-frequency generation unit 305, a crystal oscillator unit 306, and a signal power control unit 307; the second processing unit 303 is connected to the clock control unit 304, the time-frequency generation unit 305, and the signal power control unit 307 respectively; the crystal oscillator unit 306 is connected to the time-frequency generation unit 305; and the second processing unit 303 is communicatively connected to the first processing unit 302.

[0034] The first processing unit outputs the standard time signal as the timing result to the second processing unit. The second processing unit outputs a second pulse time synchronization signal to the time-frequency generation unit based on the standard time signal, and the crystal oscillator unit outputs a clock signal to the time-frequency generation unit. The clock control unit generates a clock frequency modulation signal according to the strategy parameters and sends it to the time-frequency generation unit. The time-frequency generation unit generates camouflaged time-frequency information based on the clock frequency modulation signal, the time synchronization signal, and the clock signal. The signal power control unit amplifies the camouflaged time-frequency signal according to the configured strategy parameters, and then transmits it through the transmitting antenna according to the flow instructions of the signal transmission control unit, thereby transmitting a navigation descent signal to the designated area.

[0035] Of course, in other exemplary embodiments of this disclosure, multiple backup GNSS signal simulators can also be configured. The backup GNSS signal simulators can use other existing models. The backup GNSS signal simulator is activated when the current GNSS signal simulator fails. Alternatively, according to instructions from the host computer, both the primary and backup GNSS signal simulators can be used simultaneously, transmitting navigation descent signals with different power and parameters.

[0036] For example, the first processing unit and the second processing unit mentioned above can each use FPGA devices, and the main control unit, receiving and time synchronization unit, signal generation unit and signal transmission control unit can be integrated.

[0037] For example, the host may also include a storage device, such as a hard disk, for storing operation log data, including: instruction information, descent signal information, process instruction information, timestamps and other parameters.

This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the claims.

[0039] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
