Description

Technical Field

[0001] This application relates to the field of EVTOL technology, and in particular to a remote data loading method for an electric vertical takeoff and landing aircraft. Background Technology

[0002] Electric Vertical Take-Off and Landing (EVTOL) aircraft are electrically powered aircraft capable of vertical take-off and landing like helicopters, but also capable of efficient cruising like fixed-wing aircraft during level flight. Utilizing the three pillars of electrification, vertical take-off and landing, and autopilot, EVTOL aims to solve urban traffic congestion and build a future intelligent transportation network, representing a significant step towards a greener, more inclusive, and smarter aviation industry.

[0003] Like fixed-wing aircraft, electric vertical takeoff and landing (eVTOL) aircraft require data loading for various airborne equipment, such as firmware and database updates. Currently, the common practice is for technicians to climb onto the aircraft to perform on-site data loading by contacting and plugging into the airborne equipment. This data loading method is inefficient, and the frequent contact operations pose significant challenges to the strength and electrical stability of the airframe components, increasing maintenance needs and safety hazards. Summary of the Invention

[0004] This application addresses the aforementioned problems and technical requirements by proposing a remote data loading method for an electric vertical takeoff and landing (EVTOL) aircraft. The technical solution of this application is as follows: A remote data loading method for an electric vertical takeoff and landing (EVTOL) aircraft, characterized in that the remote data loading method includes: The user terminal establishes a communication connection with the data loading terminal deployed on the electric vertical takeoff and landing aircraft. The data loading terminal provides communication interfaces of various interface types. The communication interfaces of all interactive airborne devices on the electric vertical takeoff and landing aircraft are connected to the corresponding interface type communication interfaces on the data loading terminal. The data loading terminal establishes communication with all interactive airborne devices on the electric vertical takeoff and landing aircraft. The user terminal remotely sends a data loading instruction to the data loading terminal, and the data loading instruction specifies at least each target airborne device to be loaded. The data loading terminal acquires the data to be loaded from each target airborne device and automatically loads the corresponding data to be loaded onto the target airborne devices on the electric vertical take-off and landing aircraft according to the data loading instructions.

[0005] The beneficial technical effects of this application are: This application discloses a remote data loading method for an electric vertical takeoff and landing (EVTOL) aircraft. This method involves arranging a data loading terminal on the EVTOL aircraft and connecting it to the communication interfaces of various airborne devices. A user terminal then remotely connects to the data loading terminal and sends data loading commands. The data loading terminal then automatically loads the corresponding data to be loaded onto the target airborne devices on the EVTOL aircraft according to the data loading commands. The data loading terminal integrates communication interfaces covering all airborne devices and corresponding loading transmission protocols, enabling automatic data loading and unified management and maintenance of all airborne devices, thus improving data loading efficiency. Furthermore, the remote data loading method eliminates the need for frequent plugging and unplugging of interfaces, and the contactless approach avoids damage to the aircraft body and components.

[0006] This remote data loading method supports the creation of loading task queues and supports sequential one-click loading and parallel loading of multiple airborne devices. It can not only realize parallel data loading of multiple airborne devices on electric vertical take-off and landing aircraft, but also realize parallel loading of different electric vertical take-off and landing aircraft, which greatly improves the data loading efficiency of electric vertical take-off and landing aircraft, and can achieve unattended operation and save loading time to the maximum extent.

[0007] The data loading terminal adopts a modular construction method, which can be flexibly defined to adapt to different configurations of electric vertical take-off and landing aircraft. It can well meet the application scenario requirements of electric vertical take-off and landing aircraft with diverse configurations and rapid iterations. There is no need to redesign and manufacture hardware, which improves the design efficiency and hardware utilization of the data loading terminal.

[0008] Further employing certificate-based encrypted network transmission and encrypted authentication mobile storage devices ensures data integrity, accuracy, and user identity reliability throughout the transmission process. Furthermore, the data loading terminal supports wired, wireless, external network access, remote operation, and other scenarios, making it widely applicable and adaptable to various environmental conditions. The data loading terminal can automatically record and maintain various firmware and database version information for the aircraft, which is more efficient and reliable than manual recording, achieving intelligent operation. Users only need to learn how to use the user interface provided by the data loading terminal, significantly reducing the learning curve. Moreover, regardless of changes in aircraft configuration, the user interface remains a stable and abstract interface. Attached Figure Description

[0015] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0016] This application discloses a remote data loading method for an electric vertical takeoff and landing (EVTOL) aircraft. The application scenarios of this remote data loading method include... Figure 1 As shown, it includes a user terminal and a data loading terminal, with the data loading terminal mounted on the electric vertical takeoff and landing aircraft.

[0017] The data loading terminal provides communication interfaces of various types. The communication interfaces of all interactive airborne devices on the electric vertical takeoff and landing (EVT) aircraft are connected to the corresponding communication interfaces on the data loading terminal, and the data loading terminal establishes communication with all interactive airborne devices on the EVT. Based on the conventional interface types of the airborne devices on the EVT, the communication interfaces provided by the data loading terminal include at least one of the following: A429 interface, A664 interface, CAN bus interface, and Ethernet interface.

[0018] In one embodiment, the data loading terminal includes an embedded module and multiple transmission interface modules. The embedded module integrates a processing module and its connected storage and communication modules. The processing module is equipped with an embedded system, and the embedded module also integrates a power supply module to power various electrical components. The processing module integrated in the embedded module is connected to multiple transmission interface modules, each of which provides a communication interface of a certain type.

[0019] Compared to fixed-wing aircraft, electric vertical takeoff and landing (EVTOL) aircraft are characterized by numerous configurations and rapid iteration. Different EVTOL configurations have different onboard equipment compositions, resulting in different structures for the data loading terminals deployed on them. Customizing a data loading terminal for each EVTOL configuration would be inefficient and costly. Therefore, to accommodate the complex configurations of EVTOL aircraft, the following approach is adopted for data loading terminal design: Based on the communication interfaces supported by all interactive airborne equipment on the electric vertical takeoff and landing (EVT) aircraft, the supported interface types and the number of airborne devices supporting each interface type are determined. Then, the transmission interface modules for all supported interface types are combined with embedded modules. Specifically, a processing module, storage module, communication module, and power supply module are integrated into the embedded module, with reserved inter-board connectors. Each transmission interface module is connected to the inter-board connector of the embedded module. Then, according to the number of airborne devices supporting each interface type, interface expansion modules are set at the corresponding transmission interface modules. This combination constructs a data loading terminal that matches the configuration of the EVT aircraft.

[0020] The data loading terminal, once assembled, is then deployed on the electric vertical takeoff and landing (EVTOL) aircraft and connected to all interactive onboard devices. Communication interfaces of multiple onboard devices supporting the same interface type are connected to the interface expansion modules at their respective transmission interface modules.

[0021] The interface expansion module is matched with the transmission interface module. The specific method of the interface expansion module also varies depending on the type of the transmission interface module. When the transmission interface module is a CAN transmission interface module, its matching interface expansion module is a CAN repeater. The CAN transmission interface module and all airborne devices that support the CAN bus interface are connected to an entire network topology to achieve interoperability.

[0022] When the transmission interface module is an Ethernet transmission interface module, its matching interface expansion module is a switch. Here, "Ethernet transmission interface module" includes various transmission interface modules that use Ethernet cables as the transmission medium; the specific meaning varies, and the compatible switches also differ. For example, when using an A664 Ethernet transmission interface module, a switch compatible with A664 is specifically used.

[0023] When the transmission interface module is another single-channel transmission interface module, such as the A429 transmission interface module, its matching interface expansion module is a multiplexer. Multiple airborne devices are connected to the multiplexer and then connected to the transmission interface module via different links of the multiplexer. The embedded module dynamically controls the on / off state of each link in the multiplexer. At any given time, it controls the link between one airborne device and the control transmission interface module to be on, and controls the links between other airborne devices and the control transmission interface module to be off. By switching the on / off state of different links, the connection between the transmission interface module and each airborne device can be controlled. In this way, only a single-channel transmission interface module needs to be configured, and the embedded module can be used to control the links of the multiplexer in real time, realizing concurrent one-to-many parallel loading.

[0024] By combining embedded modules with different transmission interface modules, data loading terminals adapted to different configurations of electric vertical takeoff and landing aircraft can be obtained. These data loading terminals share the hardware structure of embedded modules and transmission interface modules, eliminating the need to redesign and manufacture hardware. This not only improves the efficiency of data loading terminal construction but also increases hardware reuse rate.

[0025] For example, in one instance, suppose we are dealing with all the interactive airborne equipment on a certain configuration of electric vertical takeoff and landing (EVT) aircraft, including airborne equipment 11 to 18. Specifically, airborne equipment 11 to 14 all support the A429 interface, airborne equipment 15 and 16 both support the CAN bus interface, and airborne equipment 17 and 18 both support the Ethernet interface. Then, by connecting the embedded module to the A429 transmission interface module, the CAN transmission interface module, and the Ethernet transmission interface module, and further connecting a multiplexer to the A429 transmission interface module, a CAN repeater to the CAN transmission interface module, and a switch to the Ethernet transmission interface module, a data loading terminal adapted to this configuration of EVT aircraft can be built. Then, the data loading terminal is deployed on the corresponding configuration of the electric vertical takeoff and landing aircraft. Airborne equipment 11 to airborne equipment 14 are respectively connected to the multiplexer at the A429 transmission interface module, airborne equipment 15 and airborne equipment 16 are connected to the CAN repeater at the CAN transmission interface module, and airborne equipment 17 and airborne equipment 18 are connected to the switch at the Ethernet transmission interface module.

[0026] In another example, suppose we are dealing with an electric vertical takeoff and landing (EVT) aircraft of a different configuration, featuring all interactive onboard devices, including devices 21 through 26. Device 21 supports the A429 interface, devices 22 through 24 support the A664 interface, and devices 25 and 26 support the CAN bus interface. By connecting the embedded module to the A429, A664, and CAN transmission interface modules, and further connecting an A664 switch to the A664 transmission interface module and a CAN repeater to the CAN transmission interface module, a data loading terminal adapted to this configuration of EVT aircraft can be built. Figure 2 As shown. Then, the data loading terminal is deployed on the corresponding configuration of the electric vertical takeoff and landing aircraft. Airborne equipment 21 is connected to the A429 transmission interface module, airborne equipment 22 to airborne equipment 24 are respectively connected to the A664 switch at the A664 transmission interface module, and airborne equipment 25 and airborne equipment 26 are respectively connected to the CAN repeater at the CAN transmission interface module.

[0027] It should be noted that, Figure 1 and Figure 2 These are just examples; the actual airborne equipment in an electric vertical takeoff and landing (EVTOL) aircraft is very complex. In practical applications, the data loading terminal can be integrated into the EVTOL aircraft during the design phase, or it can be externally mounted onto an existing EVTOL aircraft.

[0028] The user terminal establishes a communication connection with the data loading terminal. In one embodiment, the communication module integrated in the data loading terminal includes at least one of an Ethernet network card, a WiFi module, and a cellular mobile communication module. The user terminal establishes a wired communication connection with the data loading terminal via Ethernet. Alternatively, the user terminal and the data loading terminal each access an external WiFi network to achieve a wireless communication connection. Alternatively, the data loading terminal has a WiFi transmission function, and in the absence of an external WiFi network, the user terminal accesses the WiFi network provided by the data loading terminal to achieve a wireless communication connection. Alternatively, the user terminal and the data loading terminal access a wireless cellular data network to achieve a wireless communication connection. Compared to using a WiFi network, this method allows the user terminal to achieve remote data loading over a longer distance without being present at the electric vertical takeoff and landing aircraft site, via the cloud.

[0029] Regardless of the method used to establish a communication connection, the user terminal remotely sends a data loading command to the data loading terminal. This command specifies at least each target airborne device to be loaded. These target airborne devices include all or some of the airborne equipment on the electric vertical takeoff and landing (EVTOL) aircraft. Furthermore, during the lifecycle of an EVTOL aircraft, multiple data loading operations are often required for its airborne equipment, and the data loading frequency varies for different devices. Therefore, the user terminal sends multiple data loading commands to the data loading terminal throughout the EVTOL aircraft's lifecycle, with any two commands indicating the same or different target airborne devices. In practical applications, the data loading terminal provides a web-based visual interface, through which the user terminal can send data loading commands to remotely initiate loading tasks.

[0030] In addition, the data loading terminal acquires the data to be loaded from each target airborne device. One approach is for the data loading terminal to remotely acquire this data from the user terminal via a communication channel. Another approach is for the embedded module of the data loading terminal to integrate a serial bus. A mobile storage device containing the data to be loaded is connected to the data loading terminal via the serial bus, and the data loading terminal acquires the data from the connected mobile storage device. These mobile storage devices include USB flash drives, external hard drives, mobile phones with similar USB flash drive functionality, MP3 players, and MP4 players.

[0031] Furthermore, to enhance data loading security, the data loading terminal acquires the encrypted data to be loaded and internally decrypts it. There are two methods for the data loading terminal to acquire the data to be loaded: one method uses an encrypted mobile storage device to store the data; the other method involves the user terminal transmitting the data to be loaded to the data loading terminal via a certificate-encrypted network transmission channel.

[0032] After acquiring the data to be loaded and receiving the remote data loading instruction, the data loading terminal can automatically load the data to be loaded onto the target airborne equipment on the electric vertical takeoff and landing aircraft according to the data loading instruction. The target airborne equipment here includes all or part of the airborne equipment on the electric vertical takeoff and landing aircraft.

[0033] The data loading command sent by the user terminal includes at least the device identifier of the target airborne device. The data loading terminal loads data onto the target airborne device based on the device identifier. When the target airborne device includes only one device, the data loading terminal directly loads data onto that device. When the target airborne device includes multiple devices, in order to minimize the total loading time while achieving one-click unattended operation, the data loading terminal automatically and continuously loads data onto multiple target airborne devices with sequential dependencies using a serial loading method, and automatically loads data onto multiple target airborne devices without sequential dependencies using a parallel loading method.

[0034] In one embodiment, the loading order among multiple target airborne devices is directly specified by the user terminal and sent to the data loading terminal in the data loading instruction. The data loading terminal receives a task loading tree in the data loading instruction. The task loading tree includes a virtual start point, a virtual end point, and several nodes. Each node in the task loading tree represents the device identifier of a target airborne device. The connection relationships between different nodes in the task loading tree conform to the dependency relationships between the target airborne devices, and these connections indicate the loading order among the corresponding target airborne devices. The task loading tree forms a tree structure. Each node in the task loading tree has a dependency relationship with its parent node. Each node needs to wait for the target airborne device corresponding to its parent node to complete data loading before it can load its own data. Each node has several parent nodes and several child nodes; the number of parent nodes or child nodes can be zero. In this embodiment, nodes without parent nodes are connected to the virtual starting point, and nodes without child nodes are connected to the virtual ending point. After receiving the data loading instruction, the data loading terminal parses the task loading tree and automatically loads the data to be loaded onto each target airborne device according to the loading order between different target airborne devices indicated by the task loading tree. This includes loading data onto the target airborne devices represented by each node in sequence according to the connection relationship between the nodes, starting from the virtual starting point of the task loading tree. Each node automatically loads data sequentially after the target airborne device of its parent node has completed data loading. Multiple nodes with the same parent node load data in parallel until the virtual ending point is reached.

[0035] For example, in one instance, an electric vertical takeoff and landing (EVTOL) aircraft includes nine onboard devices, designated as onboard devices 31 through 39. In a single data loading operation, the task loading tree included in the data loading instruction is as follows: Figure 3As shown, the task loading tree includes a virtual start point, a virtual end point, and three nodes. Node 31 corresponds to the device identifier of onboard device 31, node 35 corresponds to the device identifier of onboard device 35, and node 39 corresponds to the device identifier of onboard device 39. Node 31 is connected to the virtual start point, the parent node of nodes 35 and 39 is node 31, and both nodes 35 and 39 are connected to the virtual end point. The data loading terminal receives the data loading instruction and parses it to obtain... Figure 3 After the task loading tree is completed, data is first loaded onto airborne device 31 according to the task loading tree. After completion, data is automatically loaded onto airborne device 35 and airborne device 39 in parallel.

[0036] One approach is that the user terminal can visualize and build the mission loading tree by remotely accessing the human-computer interaction interface of the web server on the data loading terminal. The data loading terminal displays all the airborne equipment on the electric vertical take-off and landing aircraft to the user terminal, allowing the user to intuitively build the mission loading tree by connecting lines.

[0037] In another embodiment, the data loading instruction includes device identifiers of multiple target airborne devices but does not include the loading order. The data loading terminal parses the data loading instruction to obtain the device identifiers of multiple target airborne devices, and then automatically constructs the loading order between multiple target airborne devices according to the dependency relationship between all interactive airborne devices on the electric vertical take-off and landing aircraft, and automatically loads the data to be loaded to each target airborne device according to the loading order between different target airborne devices.

[0038] The onboard equipment on an electric vertical takeoff and landing (EVTOL) aircraft is fixed, and the dependencies between different onboard devices are known in advance. Therefore, a device dependency tree can be pre-built to indicate the dependencies between all interactive onboard devices on the EVTOL aircraft. The device dependency tree includes a virtual start point, a virtual end point, and several nodes. Each node in the device dependency tree represents the device identifier of an onboard device on the EVTOL aircraft. The connections between different nodes in the device dependency tree indicate the dependencies between different onboard devices on the EVTOL aircraft. Each node in the device dependency tree has a dependency on its parent node. Each node needs to wait for the target onboard device corresponding to its parent node to complete data loading before loading its own data. Each node has several parent nodes and several child nodes; the number of parent nodes or child nodes can be zero. Nodes in the device dependency tree without parent nodes are connected to the virtual start point, and nodes without child nodes are connected to the virtual end point.

[0039] The data loading terminal obtains the device dependency tree, which is typically pre-stored within the terminal. Then, the terminal retains the virtual start point, virtual end point, and nodes corresponding to the device identifiers of the target airborne devices from the dependency tree. It prunes other nodes and inherits the connections between nodes, automatically constructing the task loading tree for this task. In this task loading tree, each node represents the device identifier of a target airborne device, and the connections between different nodes indicate the loading order among the corresponding target airborne devices. Then, the terminal automatically loads the data to be loaded onto each target airborne device according to the loading order indicated by the task loading tree, following the same procedure as described above.

[0040] The specific steps for constructing the task loading tree can be as follows: The data loading terminal traverses each target airborne device, sequentially querying the parent node of that target airborne device upwards in the task loading tree. When a parent node is found that also belongs to the current target airborne device, that parent node is directly used as the parent node of the currently traversed target airborne device in the task loading tree. Alternatively, if it is determined that none of the parent nodes of the target airborne device in the task loading tree belong to the current target airborne device, it is determined that the currently traversed target airborne device has no parent node in the task loading tree. After completing the traversal, the parent node of each target airborne device in the task loading tree can be determined, and then the task loading tree can be constructed.

[0041] For example in Figure 3 In the example, the equipment dependency tree of the nine onboard devices on an electric vertical takeoff and landing aircraft is as follows: Figure 4 As shown. After parsing and determining that the target airborne equipment includes airborne equipment 31, airborne equipment 35, and airborne equipment 39, the data loading terminal retains the virtual start point, virtual end point, and the three nodes corresponding to airborne equipment 31, airborne equipment 35, and airborne equipment 39 in the device dependency tree, and inherits the connection relationships between the nodes, thus obtaining the following... Figure 3 The task loading tree shown.

[0042] This approach offers higher automation and efficiency compared to manually specifying the task loading tree, ensuring the accuracy of dependencies between airborne equipment. During multiple data loading operations on the same electric vertical takeoff and landing (EVL) aircraft, different task loading trees can be constructed by reusing the equipment dependency tree. For example, based on... Figure 4 The device dependency tree, in another data loading operation, when the target airborne devices are airborne devices 31, 33, 34, 36, and 38, automatically creates a task loading tree as follows: Figure 5As shown in the example, in this instance, the data loading terminal first loads data onto airborne device 31, then loads data onto airborne devices 33 and 34 in parallel, and then loads data onto airborne devices 36 and 38 in parallel.

[0043] For example, based on Figure 4 The device dependency tree, in another data loading operation, when the target airborne device is airborne device 32, airborne device 33, or airborne device 34, automatically creates the task loading tree as follows: Figure 6 As shown in the example, in this instance, the data loading terminal simultaneously loads data from airborne device 32, airborne device 33, and airborne device 34 in parallel.

[0044] After remotely loading data onto the target airborne equipment of the electric vertical takeoff and landing (EVT) aircraft, the data loading terminal can also generate a data loading history to automatically record and maintain the firmware versions of the airborne equipment and database. Additionally, the user terminal can obtain various data information from the EVT aircraft through the data loading terminal.

[0045] The above descriptions are merely preferred embodiments of this application, and this application is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of this application should be considered to be included within the protection scope of this application.
