Description

Secure smart avionics device for drones and its operation method

[0001] The present invention relates to a secure smart avionics device for a drone having integrated functions of flight control, mission control, navigation, security and communication, and a method for operating the same.

[0002] The content described in this section merely provides background information for the present embodiment and does not constitute prior art.

[0003] Unmanned Aerial Vehicles (UAVs) encompass various names, including drones and unmanned aircraft systems (UASs). These UAVs are aircraft that fly remotely or autonomously along designated routes without a human crew. While primarily used for military purposes, they are now being utilized in various fields, including transportation and security, and even for personal use.

[0004] These unmanned aerial vehicles (UAVs) can be remotely controlled by wirelessly communicating with ground-based control units via onboard computers, and receiving operational commands, including the required position and attitude for flight. UAVs can be manufactured in various forms, including indoors, outdoors, on the ground, in the air, and underwater, depending on the environment in which they will be used. Depending on their intended use, they can be used in a variety of applications, including filming, reconnaissance, broadcasting, industrial use, leisure activities, lifesaving, and delivery services.

[0005] However, it may be difficult for users to achieve both the usage environment and usage purpose through a single drone, and it may also be difficult to have all drones suitable for the usage environment and usage purpose.

[0006] Unmanned aerial vehicles (UAVs) come in a variety of sizes and shapes, from small, palm-sized aircraft to large, multi-meter-diameter aircraft. Large UAVs, exceeding a certain size, are larger than their main components, such as batteries, boards, and connectors. Therefore, they can be designed without design constraints or performance degradation caused by the mounting structure of these components.

[0007] However, small unmanned aerial vehicles (UAVs) below a certain size face design challenges, depending on the mounting structure of their key components. For example, the electronics for small UAVs typically require a basic board with a certain surface area, and the size and shape of the battery must also exceed certain specifications. This limits miniaturization. Furthermore, design constraints and performance degradation can arise depending on the mounting structure.

[0008] Conventional unmanned aerial vehicles (UAVs) may include specialized mission equipment tailored to their operating environment and purpose. However, each piece of equipment has different communication and operating methods, making control difficult. Typically, UAVs require a variety of power supplies (5 V, 12 V, 50 V) and data communication interfaces (RS232, GPIO, AUX, UDP, PWM). Therefore, hardware design, including power and signal processing, is complex to meet all of these specifications. Furthermore, connector pin damage (26-pin configuration) is a frequent occurrence.

[0009] One embodiment of the present invention aims to provide a secure smart avionics device for a drone and an operating method thereof for providing functions such as mission control, navigation and flight control, security and communication in an intelligently integrated modular manner.

[0010] According to one aspect of the present embodiment, there is provided an electronic assembly configured by integrating and modularizing a mission control function that performs mission processing or image processing based on mission information in conjunction with one or more external devices, and a flight control function that controls attitude, speed, and altitude based on one or more sensor signals required for flight and the mission information to fly a preset flight path and enable mission execution, flight control calculation, signal processing, or data transmission; and a housing assembly in which each module of the electronic assembly is stacked in multiple stages while being spaced apart from each other in a preset storage space; wherein the housing assembly is characterized in that each module that implements the mission control function and the flight control function is arranged separately from each other.

[0013] Alternatively, the mission control module is characterized in that it communicates with a ground control unit that generates a control signal by executing a flight control algorithm based on the operation mode.

[0014] Alternatively, the mission control module is characterized by further including a security agent verified through the Korea Cryptographic Module Validation Program (KCMVP).

[0015] Alternatively, the housing assembly is characterized by including: a housing formed in a hollow shape that forms the storage space and has a first end open; an upper plate and a lower plate that close the hollow upper and lower portions of the housing; a front plate disposed at the first end of the housing and including a connector slot for guiding insertion of at least one connector; a first gasket disposed between the upper plate and the housing; and a second gasket disposed between the lower plate and the housing.

[0016] Alternatively, the first gasket and the second gasket are characterized in that they are formed of a functional material to provide at least one of a waterproof function, a dustproof function, a heat dissipation function, a sealing function, or an electromagnetic interference (EMI) shielding function when the housing is closed by the upper plate and the lower plate.

[0017] Alternatively, the housing assembly is characterized in that it accommodates a first layer on a bottom surface in which the image interface module and the secure communication module are arranged, a second layer on an upper surface of the first layer in which the storage module and the signal processing module are arranged, and a third layer on an upper surface of the second layer in which the flight control module and the mission control module are arranged.

[0018] According to one aspect of the present embodiment, there is provided a method for operating a secure smart avionics device for a drone, which is performed by an avionics device including at least one processor, the method comprising: a mission control process for performing mission processing based on one or more sensor signals required for a mission according to an operation mode based on an inputted operation command when an operation command is inputted from the outside; a flight control process for performing a flight control function based on one or more sensor signals required for flight, and receiving an operation command from the mission control process to perform a mission-linked flight function; and a secure communication process for forming a secure communication channel between an external device and a drone through an encrypted communication function.

[0019] Alternatively, the method is characterized by further including a step of providing operational information of the drone by visualizing it through a ground control device that receives an encrypted packet transmitted during the secure communication process.

[0020] As described above, according to one aspect of the present embodiment, flight control and mission control functions can be integrated into one to achieve miniaturization, light weight, low power consumption, and low cost, and maintenance can be made easy due to the housing assembly that accommodates modules in charge of each function by stacking them in multiple stages, vibration and shock can be minimized, heat dissipation characteristics are excellent, and power consumption can be minimized by arranging the main modules separately from each other.

[0021] In addition, according to one aspect of the present embodiment, the interface of various sensors including a mission sensor and a flight sensor is possible, and by separately arranging the flight control module and the mission control module within the housing assembly, not only can data loss be minimized in the event of a drone crash, but even if a functional failure or defect occurs during the mission, flight control is possible, so that a safe return / landing is possible.

[0037] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0038] FIG. 1 is a diagram illustrating a configuration of a secure smart avionics device for a drone according to one embodiment of the present invention, FIG. 2 is an exploded view illustrating a configuration of a secure smart avionics device for a drone according to one embodiment of the present invention, and FIG. 3 is a cross-sectional view illustrating a multi-stage stacked structure of a housing assembly of a secure smart avionics device for a drone according to one embodiment of the present invention.

[0039] Referring to FIGS. 1 to 3, a secure smart avionics device (100) for a drone according to one embodiment of the present invention may include an electronic assembly (110), a housing assembly (120), and a wiring assembly (130).

[0040] The electronic assembly (110) is configured by integrating and modularizing a mission control function that performs mission processing or image processing based on mission information in conjunction with one or more external devices, and a flight control function that controls attitude, speed, and altitude based on one or more sensor signals and mission information required for flight to fly a preset flight path and enable mission execution, flight control calculation, signal processing, or data transmission.

[0041] The housing assembly (120) is configured so that each module of the electronic assembly (110) is stacked in multiple stages while being spaced apart from each other in a preset storage space, and the mission control module (210) that performs the mission control function and the flight control module (220) that performs the flight control function are arranged separately from each other.

[0042] The wiring assembly (130) may include at least one wire or cable for transmitting and receiving signals or power from each module in the electronic assembly (110).

[0043] The housing assembly (120) can accommodate a first layer in which a video interface module (230) and a secure communication module (250) are spaced apart from each other on the bottom surface (or the inner surface of the lower plate), a second layer in which a storage module (260) and a signal processing module (240) are spaced apart from each other on the upper surface of the first layer, and a third layer in which a flight control module (220) and a mission control module (210) are spaced apart from each other on the upper surface of the second layer.

[0044] At this time, the housing assembly (120) may be divided into a first layer, a second layer, and a third layer, and a support (350) may be placed so that each module is fixed within the housing assembly (120). At this time, the support (350) is formed of an insulating material, and each module may be fixed by a connecting means such as a screw.

[0045] Meanwhile, FIG. 4 is a block diagram illustrating the configuration of an electronic assembly according to one embodiment of the present invention, FIG. 5 is a drawing illustrating an interface between each module of the electronic assembly according to one embodiment of the present invention, and FIG. 6 is an exemplary diagram illustrating the configuration of an external connector according to one embodiment of the present invention.

[0046] Referring to FIG. 4, the electronic assembly (110) includes, but is not limited to, a mission control module (210), a flight control module (220), an image interface module (230), a signal processing module (240), a secure communication module (250), and a storage module (260).

[0047] When an operation mode is input from the ground control unit (10), the mission control module (210) performs mission processing based on the input operation mode. This mission control module (210) may further include a security agent (215) verified through the interoperable Korea Cryptographic Module Validation Program (KCMVP).

[0048] In addition, the mission control module (210) can perform collision avoidance and image-based autonomous landing based on deep learning through GPU operation, control of the mission sensor (30), and image processing functions for external images. Here, the mission sensor (30) can include a 3-axis gimbal camera, LiDAR, ADS-B, a thermal infrared camera, etc.

[0049] The mission control module (210) can use a deep learning-based object detection model to process an image signal input from a camera device (20). At this time, as the deep learning-based object detection model, SSD MobileNet v2, Faster R-CNN ResNet101 V1, YOLO, etc. can be used.

[0050] At this time, the ground control device (10) can communicate with the mission control module (210) and generate a control signal by executing a flight control algorithm suitable for the operation mode based on the user's operation command.

[0051] The flight control module (220) performs flight control functions including flight mode, power management, and status management based on sensor signals required for the drone's flight, and performs mission-linked flight functions in conjunction with the mission control module (210). The flight control module (220) receives sensor signals from a flight sensor to perform flight control functions, and can be interlocked with external navigation equipment. The flight sensor (40) may include an IMU, RTK-GPS, ADS-B, a barometer, a speedometer, etc. internally, and may include a laser altimeter externally.

[0052] The image interface module (230) converts raw images acquired from the camera device (20) into image signals and provides them so that they can be processed by the mission control module (210).

[0053] The signal processing module (240) acquires a sensor signal by placing a flight sensor (40), transmits an image signal to the mission control module (210) via PCIe, and provides an internal interface function for internal signal linkage between each module or an external interface function for external signal linkage with one or more external devices, as shown in FIG. 5.

[0054] In order for the signal processing module (240) to perform internal interface and external interface functions, as illustrated in FIG. 6, the housing assembly (120) includes an external connector (500), and the external connector (500) may include a main linkage connector (J1), an auxiliary linkage connector (J2), an image input connector (J3), a communication RF linkage connector (J4), and a sensor RF linkage connector (J5). Here, the auxiliary linkage connector (J2) is responsible for signal allocation to the image interface module (230), and can be used with up to 50 pins or a single 80 pin, including 2 video signal channels.

[0055] The secure communication module (250) establishes a secure communication channel between an external device and the drone through encrypted communication functions. For example, the secure communication module (250) may be equipped with a built-in quantum entropy chip (QEC) to generate secure random numbers, and may be equipped with a communication module that enables 5G, LTE, and WiFi communications.

[0056] The storage module (260) stores not only still images and videos, but also operational information generated while operating the drone, such as flight information and drone status information. The storage module (260) may include built-in memory or external memory. The built-in memory may include, for example, at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.), non-volatile memory (e.g., one time programmable ROM (OTPROM), PROM, EPROM, EEPROM, mask ROM, flash ROM, flash memory, hard drive, or solid state drive (SSD). The external memory may include a flash drive, for example, compact flash (CF), secure digital (SD), Micro-SD, Mini-SD, xD (extreme digital), multi-media card (MMC), or memory stick. When the storage module (260) includes external memory, it may be functionally or physically connected to the avionics device (100) through various interfaces.

[0057] Figure 5 is an exploded view illustrating the configuration of a housing assembly according to one embodiment of the present invention.

[0058] Referring to FIG. 5, the housing assembly (120) includes a housing (310) formed in a hollow shape with a first end open while forming a storage space, an upper plate (321) and a lower plate (322) that close the hollow upper and lower portions of the housing (310), and a front plate (323) disposed at the first end of the housing (310) and including a connector slot for guiding the insertion of at least one external connector. Here, if the first end is disposed toward the front of the housing (310), it becomes the front plate (323), but it may also become a rear plate where the first end is disposed toward the rear of the housing (310).

[0059] At this time, a first gasket (331) is placed between the upper plate (321) and the housing (310), and a second gasket (332) is placed between the lower plate (322) and the housing (310). The first gasket (331) and the second gasket (332) may be formed of a functional material to provide one or more functions of a waterproof function, a dustproof function, a heat dissipation function, a sealing function, or an electromagnetic interference (EMI) shielding function when the housing (310) is closed by the upper plate (321) and the lower plate (322).

[0060] This housing assembly (120) can be mounted on a small unmanned aerial vehicle of a certain size or less, and can be manufactured to have a weight, size, and power consumption of 0.68 kg or less, 100Х200Х50 mm or less, and 30 w or less.

[0061] The housing assembly (120) can stack each module of the electronic assembly (110) in multiple stages, thereby minimizing vibration and shock, facilitating maintenance, and providing excellent heat dissipation characteristics. In addition, each module can be divided and selectively utilized, thereby minimizing power consumption and enabling interfacing with various external devices.

[0062] In particular, the housing assembly (120) can minimize information loss in the event of a drone (or aircraft) crash by separating the mission control module (210) and the flight control module (220) from each other, and even if a malfunction or defect occurs in the mission control module (210) during the execution of a mission, flight control is possible using the flight control module (220), enabling safe return and landing.

[0063] FIG. 8 is a flowchart illustrating a method of operating a security smart avionics device for a drone according to one embodiment of the present invention.

[0064] Referring to Fig. 8, when a user's operation command is input using the ground control device (10), the input operation command is encrypted and the encrypted operation command is transmitted to a secure communication module located on the ground.

[0065] The secure communication module located on the ground transmits encrypted operation commands to the secure communication module (250) of the secure smart avionics device (100) mounted on the drone via a communication network of Wifi, LTE, or 5G.

[0066] The secure communication module (250) transmits an encrypted operation command to the mission control module (210), and after generating a quantum random key, transmits quantum random key information to the mission control module (210).

[0067] During the mission control process, the mission control module (210) decrypts the encrypted operation command and performs the mission according to the operation mode based on the operation command, and a sensor signal is input from the mission sensor (30). In addition, the mission control module (210) transmits the operation command to the flight control module (220) so that the mission-linked flight function is executed. At this time, the operation command may be mission information such as an image-based autonomous landing or a collision avoidance control command (S10).

[0068] In the flight control process, the flight control module (220) transmits operational information to the mission control module (210) after receiving a sensor signal from the flight sensor (40), determines a control command and generates a control signal, and then transmits the mission command to the mission control module (210) (S20). At this time, the mission control module (210) performs mission processing based on the mission command or mission information.

[0069] In the secure communication process, the mission control module (210) encrypts the operational information obtained from the flight control module (220) and transmits the operational information as an encrypted packet to the secure communication module (250). The secure communication module (250) transmits the encrypted packet to the secure communication module that is connected to the ground control unit (10), and the secure communication module transmits the encrypted packet together with a quantum random number key to the ground control unit (10) (S30).

[0070] The ground control device (10) can decrypt the encrypted packet to visualize the drone's operational information.

[0071] In this way, the present invention can intelligently integrate not only the mission control module and the flight control module, but also the security communication module, the signal processing module, and the image interface module, and can be arranged in a single avionics device (100) or avionics suit, so that by applying a computer with high-performance, large-capacity computing power, it can link with various sensors required for avionics operation, and can provide a system that satisfies information security standards, so that it can be utilized not only for special-purpose drones but also for various types of unmanned aerial vehicles. In addition, the present invention can secure portability that can be immediately applied by changing the operation program according to the drone model by including various options, and can provide a total avionics solution required for drones by incorporating a high-performance, high-function mission computer (mission control module) and flight computer (flight control module), so that the latest operating system can be grafted and the latest technology can be built in.

[0072] The avionics device (100) may be called various names such as avionics suit, avionics suit device, avionics equipment, etc., but in the present invention, it will be referred to as an avionics device.

[0073] Although FIG. 8 describes each process as being executed sequentially, this is merely an illustrative description of the technical idea of ​​one embodiment of the present invention. In other words, a person of ordinary skill in the art to which one embodiment of the present invention pertains can modify and apply various modifications and variations, such as changing the order described in each drawing and executing the process, or executing one or more of the processes in parallel, without departing from the essential characteristics of one embodiment of the present invention. Therefore, FIG. 8 is not limited to a chronological order.

[0074] Meanwhile, the processes illustrated in FIG. 8 can be implemented as computer-readable code on a computer-readable recording medium. A computer-readable recording medium includes all types of recording devices that store data that can be read by a computer system. That is, a computer-readable recording medium includes storage media such as magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.) and optical reading media (e.g., CD-ROMs, DVDs, etc.). In addition, a computer-readable recording medium can be distributed across network-connected computer systems, so that the computer-readable code can be stored and executed in a distributed manner.

[0075] The above description is merely an example of the technical idea of ​​the present embodiment, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present embodiment. Therefore, the present embodiments are not intended to limit the technical idea of ​​the present embodiment, but rather to explain it, and the scope of the technical idea of ​​the present embodiment is not limited by these embodiments. The scope of protection of the present embodiment should be interpreted by the claims below, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of rights of the present embodiment.
