Description

Technical Field

[0001] This invention relates to the field of low-altitude safety unmanned aerial vehicle (UAV) detection technology, specifically to a device and method for aggregating UAV detection information from multiple detection modules into a communication module. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly widely used in civilian and commercial fields, but this also brings safety hazards for low-altitude flight. Therefore, the importance of drone detection technology is becoming increasingly prominent. Existing drone detection methods generally adopt a configuration mode of "single detection motherboard + single communication module", in which the communication module only undertakes data transmission function and does not participate in any information processing. All detection tasks are completed by a single detection motherboard.

[0003] This existing technology has obvious drawbacks: on the one hand, the detection range of a single detection motherboard is limited, the density of drone detection information acquired is insufficient, and obvious detection blind spots are likely to occur, making it impossible to achieve all-round drone signal coverage; on the other hand, a single detection motherboard paired with an ordinary antenna has a short detection distance, making it difficult to capture drone signals flying at long distances, and thus failing to meet the needs of long-distance early warning and all-round monitoring of drones in practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for summarizing information from multiple detection modules of unmanned aerial vehicles (UAVs) into a communication module, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for aggregating information from multiple detection modules of a UAV to a communication module, comprising multiple detection modules, a communication module, a PCB motherboard, and a power supply unit, characterized in that: the multiple detection modules, the communication module, and the power supply unit are all integrated and mounted on the PCB motherboard; the multiple detection modules are all connected to external antennas; and the multiple detection modules are connected in series via G17 and G18 interfaces to form a cascaded transmission link; the communication module is connected to the end detection module of the series link via G17 and G18 interfaces; the power supply unit provides a 5V operating voltage and is connected to the VIN interface of the PCB motherboard.

[0006] As a preferred embodiment of the present invention, the plurality of detection modules include 6 directional detection modules and 1 omnidirectional detection module.

[0007] As a preferred embodiment of the present invention, the communication module integrates a signal receiving unit and an information uploading unit.

[0008] As a preferred embodiment of the present invention, in the serial link, the UAV detection information acquired by any detection module is transmitted step by step to the previous detection module through the G17 interface and the G18 interface, and finally transmitted to the communication module.

[0009] A communication method for aggregating UAV detection information from multiple detection modules to a communication module, the method comprising the following steps:

[0010] Step 1, Module Assembly: Attach 6 directional detection modules, 1 omnidirectional detection module and 1 communication module to the 6+1+1 structure PCB motherboard, complete the circuit connection of each module, and connect the corresponding antenna to each detection module. The directional detection module is connected to a directional antenna, and the omnidirectional detection module is connected to an omnidirectional antenna.

[0011] Step 2, Link Setup: Connect multiple detection modules in series via G17 and G18 interfaces to form a cascaded transmission link. Connect the detection module at the end of the series link to the communication module via G17 and G18 interfaces to complete the construction of the communication system.

[0012] Step 3, Power-on startup: The power supply unit provides 5V voltage to the VIN interface of the PCB motherboard to start the detection module and communication module, enabling each module to enter the working state;

[0013] Step 4, Signal Detection: Each detection module detects the drone's broadcast signal in real time through an external antenna. The directional detection module focuses on detecting long-distance drone signals, while the omnidirectional detection module fills in detection blind spots, achieving all-round drone signal detection.

[0014] Step 5, Information Transmission: Each detection module transmits the detected UAV information to the previous detection module through the G17 and G18 interfaces, step by step, until it is transmitted to the communication module, thus completing the aggregation of detection information from multiple modules;

[0015] Step 6, Information Upload: The communication module will upload all the collected drone detection information to the backend terminal in real time for staff to view and process.

[0016] Preferably, in step 5 of this invention, the transmission of the detection information adopts a cascaded progression.

[0017] In this way, if any detection module fails, it will not affect the information transmission and aggregation of the preceding detection modules.

[0018] As a preferred embodiment of the present invention, in step 4, the directional detection module enhances the detection capability of long-distance UAV signals through the directional receiving characteristics of the directional antenna, and the omnidirectional detection module eliminates the blind spots caused by single directional detection through the omnidirectional receiving characteristics of the omnidirectional antenna.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This multi-detection module is a device that aggregates drone information to a communication module. By connecting and aggregating multiple detection modules in series, and combining six directional detection modules with one omnidirectional detection module, it effectively compensates for the detection blind spots caused by a single detection motherboard. At the same time, the directional antenna increases the drone detection range, solving the problems of short detection range and insufficient information density in existing technologies, and realizing omnidirectional and long-distance detection of drone signals.

[0021] This multi-detection module is a device that aggregates UAV information to the communication module. It uses G17 and G18 interfaces to connect multiple detection modules in series, resulting in a simple and stable link structure. Information transmission adopts a cascaded and progressive method, so if any detection module fails, it will not affect the information transmission and aggregation of the preceding detection modules, ensuring the stability and reliability of the system. The communication module only undertakes the functions of information aggregation and transmission, avoiding the delay caused by additional information processing and improving the real-time performance of information transmission.

[0027] Please refer to Figures 1-2, which illustrate one embodiment of the present invention:

[0028] Example 1

[0029] A device for aggregating information from multiple detection modules detected by a drone to a communication module includes multiple detection modules, a communication module, a PCB motherboard, and a power supply unit. The multiple detection modules, communication module, and power supply unit are all integrated and mounted on the PCB motherboard. Each of the multiple detection modules has an external antenna, and the multiple detection modules are connected in series via G17 and G18 interfaces to form a cascaded transmission link. The communication module is connected to the detection module at the end of the series link via G17 and G18 interfaces. The power supply unit provides a 5V operating voltage and is connected to the VIN interface of the PCB motherboard.

[0030] In this embodiment, the multiple detection modules include six directional detection modules and one omnidirectional detection module; the communication module integrates a signal receiving unit and an information uploading unit; in the serial link, the UAV detection information acquired by any detection module is transmitted step by step to the previous detection module through the G17 and G18 interfaces, and finally transmitted to the communication module; the components work closely together, with a high degree of integration, stable transmission, and comprehensive detection, which can effectively meet the usage requirements of UAV signal detection and information aggregation.

[0031] In this embodiment, the PCB motherboard adopts a 6+1+1 structure, that is, it reserves 6 mounting positions for directional detection modules, 1 mounting position for omnidirectional detection modules, and 1 mounting position for communication modules. Each mounting position is equipped with corresponding circuits.

[0032] The interface ensures circuit continuity after each module is attached, and the integrated design simplifies wiring connections and reduces signal interference. The power supply unit uses a DC power supply module with a stable output voltage of 5V and a rated current adapted to the working requirements of each module. It is fixedly connected to the VIN interface of the PCB motherboard by soldering to ensure stable power supply and avoid poor contact.

[0033] The directional detection module uses a high-gain directional detection chip, enabling long-distance signal detection with a range of 1-3 kilometers. The external directional antenna is made of fiberglass, providing strong directionality and accurately capturing drone signals from specific directions. The omnidirectional detection module uses an omnidirectional detection chip, covering a 360° detection angle. The external omnidirectional antenna employs an omnidirectional design, effectively compensating for the blind spots of the directional detection module and achieving all-around detection. The G17 and G18 interfaces of each detection module use standardized interfaces, ensuring convenient plugging and unplugging, tight connections, and smooth signal transmission.

[0034] The communication module uses an industrial-grade communication chip. The signal receiving unit can simultaneously receive transmission information from multiple detection modules and has strong anti-interference capabilities. The information uploading unit supports 4G / 5G wireless transmission and can upload the aggregated detection information to the back-end terminal in real time with low transmission latency and high reliability. The back-end terminal uses dedicated monitoring software to display the detection information of each detection module in real time, including the drone's location, signal strength, and flight trajectory, which is convenient for staff to view and process.

[0035] A communication method for aggregating UAV detection information from multiple detection modules to a communication module, applied to the aforementioned communication equipment, includes the following steps:

[0036] Step 1, Module Assembly: Attach 6 directional detection modules, 1 omnidirectional detection module, and 1 communication module to a 6+1+1 PCB motherboard. Complete the circuit connection of each module by soldering to ensure that each module is conductive with the PCB motherboard circuit. Connect a corresponding antenna to each detection module. Connect a directional antenna to the directional detection module and an omnidirectional antenna to the omnidirectional detection module. The interface between the antenna and the detection module is threaded to ensure a firm connection and avoid signal attenuation.

[0037] Step 2, Link Setup: Connect the six directional detection modules and one omnidirectional detection module in series via interfaces G17 and G18 to form a cascaded transmission link. Tighten the connections after connecting the interfaces to ensure smooth signal transmission. Connect the end detection module and communication module of the series link via interfaces G17 and G18.

[0038] Connect the ports to complete the construction of the communication system. After the construction is completed, check the connection status of each interface to avoid poor contact.

[0039] Step 3, Power Supply Start-up: The power supply unit provides 5V voltage to the VIN interface of the PCB motherboard, turns on the power switch, and the power supply unit begins to output voltage stably; the detection module and communication module are started, and each module enters normal working state after completing self-test. At this time, the detection module begins to capture drone signals through the external antenna, and the communication module is in signal receiving ready state.

[0040] Step 4, Signal Detection: Each detection module detects the drone's broadcast signal in real time through an external antenna. The six directional detection modules face different directions and use the directional receiving characteristics of the directional antenna to focus on detecting long-distance drone signals and expand the detection range. The one omnidirectional detection module uses the omnidirectional receiving characteristics of the omnidirectional antenna to make up for the blind spots caused by single directional detection, achieving 360° omnidirectional drone signal detection and ensuring no signal is missed.

[0041] Step 5, Information Transmission: Each detection module transmits the detected UAV information (including UAV position coordinates, signal strength, flight speed, flight trajectory, etc.) to the previous detection module through the G17 and G18 interfaces, forming a cascaded transmission mode, until all detection information is aggregated and transmitted to the communication module. During this transmission process, if any detection module fails, the failed module stops transmitting its own detection information, but does not affect the information transmission of other detection modules, ensuring the stability and integrity of the aggregated information.

[0042] Step 6, Information Upload: The communication module, through its integrated information upload unit, uploads all the collected drone detection information to the back-end terminal in real time via 4G / 5G wireless transmission. The monitoring software on the back-end terminal displays each detection information in real time, and staff can monitor the drone's flight status in real time based on the uploaded information, and carry out subsequent supervision, early warning and handling.

[0043] In this embodiment, in step 5, the transmission of detection information adopts a cascaded progressive method, so that if any detection module fails, it will not affect the information transmission and aggregation of the preceding detection modules; in step 4, the directional detection module improves the detection capability of long-range UAV signals through the directional receiving characteristics of the directional antenna, and the omnidirectional detection module eliminates single directional detection bands through the omnidirectional receiving characteristics of the omnidirectional antenna.

[0044] The blind spot that came from here.

[0045] In this embodiment, the daily maintenance process of the communication system and method is as follows: Regularly check the bonding status and circuit connection of each module on the PCB motherboard. If any loosening or desoldering is found, repair it by soldering in a timely manner. Check the connection status of each interface to ensure that the G17 interface, G18 interface and VIN interface are tightly connected to avoid abnormal signal transmission. Check the antenna connection status. If any loosening is found, tighten it in a timely manner to avoid signal attenuation. Regularly check the output voltage of the power supply unit to ensure a stable output voltage of 5V. If any voltage abnormality is found, repair or replace the power supply unit in a timely manner. Regularly clean the dust and debris on the surface of the equipment to avoid affecting the heat dissipation and normal operation of the equipment. Regularly update the software of the back-end terminal to ensure normal information reception and display.

[0046] Applicable scenarios: It can be widely used in scenarios requiring all-round drone detection and monitoring, such as airports, railway stations, convention centers, industrial parks, military restricted areas, and urban security. It can achieve long-distance, all-round detection of drone signals, quickly collect and upload detection information, provide accurate data support for staff, and effectively prevent safety hazards caused by illegal drone flights.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
