DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] The Tiantong satellite system is a satellite mobile communication system that mainly provides communication services such as voice, short message, and data. Special satellite mobile phones or terminals support voice calls, short messages, and data transmission. Application scenarios include scenes without ground network coverage such as emergency rescue, marine fishery, and geological exploration. It is autonomous and controllable, with high security, making up for the ground communication blind area and suitable for the needs of special industries.

[0020] The Beidou system is a global satellite navigation system (similar to GPS), but its unique function is to have the short message communication ability. It can send short text or position information through satellites. The communication method is two-way short message, without relying on the ground network. It integrates navigation and communication, with low power consumption and high reliability, and is suitable for extreme environments.

[0021] 4G (LTE) and 5G are the mainstream terrestrial mobile communication technologies. Based on cellular networks, they provide high-speed data transmission and wide-area coverage, with high bandwidth and low latency, and support the connection of a large number of devices.

[0022] Existing multi-mode communication modules are usually the pairwise integration of Tiantong, Beidou, and 4G / 5G, each having its own advantages and disadvantages. There is currently no module that can simultaneously address the shortcomings of existing communications and integrate the advantages of all parties. The disadvantages of pairwise integration are shown in Table 1: Table 1: Comparison table of the functions and disadvantages of pairwise combinations of communication modules

[0023] The multi-mode satellite communication - Ascend computing power integration module described in the preferred embodiment of the present invention, as Figure 1 shown, the multi-mode satellite communication - Ascend computing power integration module includes: Ascend NPU chip, which is used to run a scheduling model based on AI algorithms, perform real-time prediction on the drone and evaluate link delay, bandwidth, and power consumption. At the same time, according to the path planning algorithm and obstacle avoidance algorithm, it dynamically selects the optimal communication mode among Tiantong satellite communication, Beidou-3 short message communication, and 4G / 5G communication; Tiantong satellite communication module, which is used to transmit the status log of the drone; Beidou positioning and short message module, which is used to transmit the drone's position, status, and emergency messages; 4G / 5G module, which is used to transmit real-time control instructions, high-definition pictures, and high-definition video streams; IMU module (Inertial Measurement Unit, which is a sensor device used to measure the acceleration, angular velocity, and attitude of an object), which is used for integrated navigation and positioning in combination with Beidou GNSS, provides autonomous navigation capabilities when the GNSS signal is interrupted, and corrects the GNSS multipath error at the same time; Antenna, which is used to transmit and receive wireless signals.

[0024] Among them, the Ascend NPU chip refers to the Huawei Ascend series of AI processors (chips, which are designed to provide powerful computing power support for artificial intelligence applications). The Ascend NPU chip runs edge computing, AI algorithms, etc. Based on multi-modal heterogeneous data fusion and multi-model collaborative prediction such as the CNN-LSTM model and the hardware acceleration of the Ascend NPU, it real-time predicts link delay, bandwidth, and power consumption, realizes the second-level evaluation of delay, bandwidth, and power consumption, and dynamically optimizes the selection of communication links.

[0025] The specific process by which the Ascend NPU chip dynamically selects the optimal communication mode according to the path planning and obstacle avoidance algorithms includes: (1) Data fusion: Align the path coordinates, obstacle distribution, and real-time communication channel status (5G / Beidou / Thianlong signal strength) to a unified spatio-temporal coordinate system; (2) Signal occlusion / attenuation prediction: Use CNN to analyze the shape and density of obstacles on the path within a preset future time (e.g., the next 5 - 10 seconds), and predict signal attenuation areas (e.g., 5G attenuation caused by building occlusion, or Beidou attenuation when entering a pipe gallery); (3) Communication decision-making: Use a reinforcement learning algorithm (Q-Learning, a classic model-free reinforcement learning algorithm belonging to the Temporal Difference (TD) learning method. It optimizes the decision-making strategy of an agent (such as a drone or a robot) by continuously updating the action value function (Q function), and finally learns to take optimal actions in a specific environment to maximize the cumulative reward) to comprehensively consider path risk, latency prediction, and energy consumption constraints, and generate an optimal communication mode among Thianlong satellite communication, Beidou-3 short message communication, and 4G / 5G communication (e.g., switch to Thianlong + Beidou redundancy before entering the 5G occlusion area), and achieve end-to-end decision-making through Ascend parallel computing; (4) Protocol optimization: Dynamically allocate resources according to the NPU computing power to ensure the transmission of high-priority data such as obstacle avoidance instructions.

[0026] Among them, the Thianlong satellite communication module is used to transmit the drone status log (e.g., to the user side, i.e., the side that needs data and graphics), to ensure basic communication needs.

[0027] Among them, the Beidou positioning and short message module is used to transmit the drone position, status, and emergency messages (e.g., to the user side, i.e., the side that needs data and graphics).

[0028] Among them, the 4G / 5G module is used to transmit real-time control instructions, high-definition pictures, and high-definition video streams (e.g., to the user side, i.e., the side that needs data and graphics).

[0029] Among them, the IMU module is used for integrated navigation and positioning in combination with Beidou GNSS. The IMU module provides autonomous navigation capabilities when the GNSS signal is interrupted, and at the same time corrects the GNSS multipath error to achieve continuous and high-precision integrated positioning, improving the robustness of the drone's navigation system in complex environments.

[0030] Among them, the antenna includes: Thianlong external antenna, Beidou external antenna, 4G / 5G external antenna, WIFI / Bluetooth antenna, which are used to transmit and receive wireless signals.

[0031] Among them, the communication protocol has a redundancy path, that is, in Tiantong satellite communication, Beidou-3 short message communication, and 4G / 5G communication, two communication protocols are always kept in an active state to prevent switching errors.

[0032] Among them, the multi-mode satellite communication-Ascend computing power integration module further includes: a communication interface, which is used for communication connection with external devices. The communication interface includes: RS-232, RS-485, WIFI, and Bluetooth. RS-232 and RS-485 are used to connect devices such as sensors. Mobile terminal devices such as mobile phones / PADs (Portable Android Device or Portable Data Terminal, portable intelligent terminals integrated with data collection, processing, and communication functions) can send and receive data through Bluetooth or WIFI.

[0033] Furthermore, based on the multi-mode satellite communication-Ascend computing power integration module, the present invention also provides a data processing method. The data processing method in the preferred embodiment of the present invention is as Figure 2 and Figure 3 shown. The data processing method includes: Step S10: Obtain external data, and input the external data into the multi-mode satellite communication-Ascend computing power integration module. The external data includes real-time status of the unmanned aerial vehicle, environmental information, and flight control instruction information; Step S20: The Ascend NPU chip runs a scheduling model based on an AI algorithm to perform real-time prediction on the unmanned aerial vehicle and evaluate link delay, bandwidth, and power consumption. At the same time, according to the path planning algorithm and obstacle avoidance algorithm, the optimal communication mode is dynamically selected among Tiantong satellite communication, Beidou-3 short message communication, and 4G / 5G communication.

[0034] Specifically, step S20 specifically includes: Step S21: The Ascend NPU chip aligns path coordinates, obstacle distribution, and real-time communication channel status (5G / Beidou / Tiantong signal strength) to a unified spatio-temporal coordinate system; Step S22: The Ascend NPU chip uses CNN to analyze the form and density of obstacles on the path within a preset future time (such as the next 5-10 seconds), and predict signal attenuation areas (such as 5G attenuation caused by building occlusion, and Beidou attenuation caused by entering a pipe gallery); Step S23: The Ascend NPU chip uses a reinforcement learning algorithm (Q-Learning) to comprehensively consider path risk, delay prediction, and energy consumption constraints to generate an optimal communication mode among Tiantong satellite communication, Beidou-3 short message communication, and 4G / 5G communication (such as switching to Tiantong+Beidou redundancy before entering the 5G occlusion area), and realizes end-to-end decision-making through Ascend parallel computing; Step S24: The Ascend NPU chip dynamically allocates resources according to the NPU computing power to ensure the transmission of high-priority data such as obstacle avoidance instructions.

[0035] Among them, the path planning algorithm (the UAV path planning algorithm is the core technology to ensure the efficient and safe completion of the UAV flight mission, involving key links such as environmental perception, dynamic obstacle avoidance, and optimal path generation, such as genetic algorithms and ant colony algorithms) is used to generate flight trajectories, and the obstacle avoidance algorithm (the UAV obstacle avoidance algorithm is the core technology to ensure the safe flight of the UAV in a complex environment, mainly by using sensors to perceive obstacles and adjust the flight path in real time, such as end-to-end obstacle avoidance and semantic segmentation assistance) is used to output a real-time obstacle heat map (the real-time obstacle heat map is a tool that intuitively displays the distribution and threat level of obstacles in the environment through dynamic visualization technology, and is widely used in fields such as autonomous driving, UAV navigation, robot obstacle avoidance, and security monitoring).

[0036] Generating the optimal communication mode in Tiantong satellite communication, Beidou-3 short message communication, and 4G / 5G communication specifically includes: Previously, perform a priority sorting from high to low in the order of 4G / 5G communication, Beidou-3 short message communication, and Tiantong satellite communication; Monitor the 4G / 5G signal strength and delay. When the delay is greater than the preset delay threshold (for example, delay > 20ms) or the RSRP (Reference Signal Receiving Power) is less than the preset signal receiving power threshold (for example, RSRP < -110dBm), that is, when in a state of weak signal or sudden increase in delay, activate the Beidou-3 short message communication; When the Beidou short message channel information is congested or in a preset occlusion environment (for example, entering a severely occluded environment such as underground or culvert), and the 4G / 5G communication has not recovered to normal, switch to Tiantong satellite communication to ensure basic communication. Automatically switch back to the mode with the highest priority according to the recovery of 4G / 5G and Beidou.

[0037] External data (such as obtaining its own status and collecting environmental information by sensors on the drone, as well as instructions from the management center, etc.) is input into the multi-mode satellite communication-Ascend computing power integration module, including: 1) Real-time status, such as the pose status and video frequency of the drone; 2) Environmental information, such as obstacles and no-fly zones; 3) Flight control instruction information, such as ascending, descending, and returning. Based on the support of the Ascend NPU, intelligent communication channel prediction and scheduling as well as flight control coordination are realized, the coupling optimization adjustment of flight control instructions and communication instructions is achieved, and the status of the 4G / 5G, Beidou, and Tiantong communication links is evaluated and predicted by combining the module input and historical link data status indicators. At the same time, flight control algorithms such as path planning and obstacle avoidance are run, and the link priority is dynamically defined according to the flight instructions in combination with the flight state parameters. At the same time, the Ascend NPU is used to perform feature extraction on large amounts of data such as images for flight control and environmental input based on neural network algorithms, compress the data volume, and meet the protocol lightweight requirements in low-bandwidth situations (which refers to optimizing the data transmission method in a low-bandwidth environment, reducing redundant information, minimizing the data volume, and ensuring the efficient transmission of key information. It includes: performing feature extraction and compression on image or environmental data through hardware acceleration of the Ascend NPU to run lightweight neural networks in real time; dynamically adjusting the compression ratio based on real-time analysis of the link quality by the NPU).

[0038] Furthermore, redundant communication links are defined according to the flight mission. At the same time, the redundant communication links remain in a hot standby state, regularly apply for channels, and preload the transmission context to reduce the handover delay. As shown in Table 2: Table 2: Allocation relationship between the main link and the redundant link

[0039] Furthermore, finally, through the optimal communication mode, instructions, messages, etc. are sent to mobile terminal devices such as mobile phones / PADs, drones, and the data management center.

[0040] As Figure 3 shown, external data (drone status, environmental video frequency, flight control instructions, etc.) is obtained as the hardware board (i.e., the multi-mode satellite communication-Ascend computing power integration module of the present invention). With the support of the Ascend NPU computing power, the intelligent prediction and scheduling engine predicts and evaluates the link status, dynamically selects the optimal communication mode, and the intelligent flight control coordination engine uses lightweight protocols to meet the dynamic protocol requirements based on flight control algorithms. Finally, through the optimal communication mode, instructions, messages, etc. are sent to mobile terminal devices such as mobile phones / PADs, drones, and the data management center.

[0041] The technical effects that the present invention can bring are as follows: (1) Realize three-mode redundant communication and full-region coverage.

[0042] (2) Achieve three-mode dynamic scheduling through the computing power of Ascend NPU to solve the problems of insufficient regional coverage and unstable signals existing in single / double communication modes.

[0043] (3) Combine the requirements of flight control algorithms such as path planning, perform unified scheduling by Ascend, jointly optimize protocol scheduling, achieve real-time resource allocation, and reduce communication energy consumption.
