Description

Technical Field

[0001] This disclosure relates to the field of vehicle remote control technology, and more specifically, to a data transmission method, a data transmission device, an electronic device, and a computer program product. Background Technology

[0002] Autonomous vehicles have wide applications in various operational scenarios. For example, cab-less wide-body dump trucks can be used for coal transportation and soil dumping in mines. Currently, the operation of autonomous vehicles mainly relies on 5G private networks for autonomous control, while short-range remote control uses point-to-point communication, which suffers from severely limited communication distance.

[0003] When driverless vehicles malfunction or require maintenance, vehicles with cabs can be driven directly to the repair area by the operator. However, wide-body dump trucks without cabs face difficulties in movement. Traditional remote control equipment has a narrow operating range, requiring operators to be close to the vehicle for operation. This not only exposes operators to potential hazards in the working environment, such as the risk of collision during vehicle movement, but also makes precise control difficult, easily leading to operational errors or safety accidents.

[0004] Therefore, there is an urgent need in the field for a method that enables operators to stably acquire images of vehicle status and environment from a safe distance, in order to solve the problem of moving driverless vehicles in fault conditions and to ensure the safety and reliability of the remote control process.

In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0022] Furthermore, the accompanying drawings are merely illustrative of this disclosure 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 software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0023] This example implementation first provides a data transmission method applied to a remote control terminal. (See reference...) Figure 1 As shown, the above data transmission method may include the following steps: Step S110. Match the remote control terminal with the ad hoc network where the vehicle terminal is located. After successful matching, obtain and display the link status of the ad hoc network and the initial status of the vehicle terminal.

[0024] Step S120. Send a transmission start command to the vehicle terminal to activate the image transmission function based on the self-organizing network.

[0025] Step S130. Acquire and display the real-time environmental image around the vehicle terminal sent by the vehicle terminal through the image transmission function.

[0026] This example implementation also provides a data transmission method applied to a vehicle terminal. (See reference) Figure 2 As shown, the above data transmission method may include the following steps: Step S210. After the remote control terminal and the vehicle terminal are successfully matched in the ad hoc network, the initial state of the vehicle terminal is sent to the remote control terminal.

[0027] Step S220. Receive the transmission start command sent by the remote control terminal and activate the image transmission function based on the self-organizing network on the vehicle terminal.

[0028] Step S230. Collect real-time environmental images of the vehicle's surroundings using the vehicle-mounted camera, and send the real-time environmental images to the remote control terminal via the image transmission function.

[0029] In the data transmission method of this exemplary embodiment, the remote control terminal is matched with the ad hoc network where the vehicle terminal is located. After successful matching, the remote control terminal acquires and displays the link status of the ad hoc network and the initial state of the vehicle terminal. Then, the remote control terminal sends a transmission start command to the vehicle terminal, causing the vehicle terminal to activate the image transmission function based on the ad hoc network. The vehicle-mounted camera captures real-time environmental images around the vehicle terminal and sends these images to the remote control terminal for display. This data transmission method, by integrating line-of-sight remote control with ad hoc network image transmission technology, allows operators to precisely control the movement of unmanned vehicles from a safe distance using a combination of line-of-sight observation and real-time image transmission. This effectively solves the problem of inconvenient movement during unmanned vehicle malfunctions or maintenance, improving remote control stability, safety, and ease of operation.

[0030] The steps described above in this example implementation will now be explained in more detail.

[0031] In step S110, the remote control terminal is matched with the ad hoc network where the vehicle terminal is located. After successful matching, the link status of the ad hoc network and the initial status of the vehicle terminal are obtained and displayed.

[0032] In this example implementation, a self-organizing network (SAN) is a wireless network that does not rely on any pre-existing network infrastructure. Nodes in the network automatically and spontaneously organize and maintain a complete communication system through protocols. A SAN is essentially an intranet, with each terminal acting as a network node. The link status of a SAN refers to the quality indicators of the communication links within the SAN, which may include status parameters such as the number of nodes, signal strength, and packet loss rate. The initial state of the vehicle terminal refers to the operating parameters of the vehicle terminal when a successful match is achieved, which may include engine status, gear position, fault conditions, etc., primarily to determine whether the vehicle can operate normally.

[0033] In this example implementation, the operator can hold a remote control terminal with a display screen and start the remote control terminal at a safe location in the work area (such as 50-500 meters away from the vehicle, ensuring line of sight). The remote control terminal will then pair with the ad hoc network where the vehicle terminal is located. After successful pairing, the display screen will show the ad hoc network link status and the initial vehicle status, allowing the operator to assess the connection quality and vehicle condition.

[0034] In step S120, a transmission start command is sent to the vehicle terminal to activate the image transmission function based on the self-organizing network.

[0035] In this example implementation, the operator can send a transmission start command to the vehicle terminal via a remote control terminal to activate the vehicle-mounted ad hoc network image transmission module and enable the vehicle terminal's image transmission function based on the ad hoc network. The image transmission function refers to the ability to transmit image data through the ad hoc network, which can be implemented using a video streaming protocol. Its main purpose is to transmit images of the vehicle's surrounding environment to the remote control terminal.

[0036] In step S130, the real-time environmental image around the vehicle terminal, sent by the vehicle terminal through the image transmission function, is acquired and displayed.

[0037] In this example implementation, after the vehicle terminal activates the image transmission function based on the self-organizing network, the real-time environmental images captured by the vehicle terminal's camera can be transmitted to the remote control terminal through the self-organizing network. The operator can view the real-time images on the remote control terminal's display screen and, in conjunction with line-of-sight observation, gain a comprehensive understanding of the vehicle's surrounding environment.

[0038] For example, when an operator starts the remote control terminal in a safe location in a mining or other work area and completes pairing with the self-organizing network, the operator judges the feasibility of remote control based on the displayed link status and initial status. After activating the image transmission function, the operator observes the dynamic environment around the vehicle in real time to achieve precise control. This solves the problems of inconvenient movement of cab-less wide-body dump trucks during malfunctions or maintenance, high risks for operators, and inability to obtain information about the vehicle's surrounding environment.

[0039] In this example implementation, a wireless image transmission remote control system between a remote control terminal and a vehicle terminal can be developed based on a self-organizing network and using a self-organizing network radio in a specified frequency band. The wireless image transmission remote control system supports simultaneous transmission of multiple data streams.

[0040] Based on an IP Mesh self-organizing network (a wireless mesh network architecture based on the IP protocol), a wireless image transmission and remote control system is developed using a designated frequency band, such as 1.4GHz, with Mesh self-organizing radios. This system features self-organization, self-recovery, and high resilience, supporting multi-hop transmission of data, video, and other multimedia services. It supports wireless transmission distances exceeding 10 kilometers and can simultaneously transmit four video streams and control signals. Multi-channel data transmission overcomes the limitations of single-channel transmission, allowing simultaneous transmission of multiple environmental images or composite data, enabling synchronous acquisition and efficient transmission of images from multiple vehicle-mounted cameras.

[0041] In this example implementation, vehicle control commands can also be sent to the vehicle terminal via a self-organizing network, so that the vehicle terminal can move based on the vehicle control commands.

[0042] Operators can remotely control the vehicle's movement by combining visual observation with images on the display screen. Based on the obtained environmental information, operators send control commands via remote control to achieve precise remote control of the cabless wide-body dump truck, enabling it to be safely moved to a designated location (such as a maintenance area).

[0043] The remote control terminal utilizes the dynamic routing capabilities of ad hoc networks to ensure reliable transmission of control signals. This avoids the distance limitations of traditional point-to-point communication in complex terrain, ensuring continuous delivery of commands even in obstacle-filled environments such as mines. The vehicle terminal parses the received commands and translates them into physical actions. This can be achieved by using an onboard controller to drive a motor or steering actuator via a CAN bus. The purpose is to translate the operator's intentions into vehicle movement in real time, providing the execution basis for precise remote control. After the vehicle terminal executes a movement, environmental changes are fed back to the remote control terminal in real time via image transmission, thus achieving a cyclical iteration of command transmission, action execution, and visual verification. This mechanism fully leverages the topology adaptive characteristics of ad hoc networks, automatically optimizing the data transmission path during vehicle movement to ensure the synchronization and reliability of control commands and image data. This allows operators to continuously adjust command content based on dynamic environmental information.

[0044] In this example implementation, a relay station can also be added between the remote control terminal and the vehicle terminal.

[0045] A relay station is a network device used for signal relay. It can be implemented using a radio station or a wireless repeater. Its purpose is to extend the communication coverage and enhance the continuity of signal transmission, thereby overcoming the signal attenuation problem caused by excessive physical distance or obstruction.

[0046] By adding relay stations between the remote control terminal and the vehicle terminal based on actual conditions, the relay stations can receive signals from either the remote control terminal or the vehicle terminal and re-forward them, thereby extending the communication distance, overcoming terrain obstacles, and achieving wider communication coverage. Relay stations can provide additional signal paths between major communication nodes, enhancing network robustness, reducing signal attenuation, improving overall network performance, and avoiding the risk of transmission interruptions caused by signal attenuation in direct communication mode.

[0047] In step S210, after the remote control terminal and the self-organizing network where the vehicle terminal are located are successfully matched, the initial state of the vehicle terminal is sent to the remote control terminal.

[0048] In this example implementation, after the remote control terminal and the vehicle terminal are successfully matched in the ad hoc network, the initial state of the vehicle terminal is transmitted, which enables the operator to accurately assess whether the vehicle is in an operable state.

[0049] In step S220, a transmission start command sent by the remote control terminal is received to activate the image transmission function based on the self-organizing network on the vehicle terminal.

[0050] In this example implementation, by activating the image transmission function in response to remote terminal commands, the efficiency of vehicle resource utilization can be optimized, ensuring that image transmission is only started when needed.

[0051] In step S230, real-time environmental images of the vehicle's surroundings are captured by the vehicle-mounted camera and sent to the remote control terminal via the image transmission function.

[0052] By using an onboard high-definition network camera to capture real-time images of the vehicle's surrounding environment and transmitting these images to a remote control terminal via a self-organizing network transmission mechanism, operators can perform precise remote control operations from a safe location, combining line-of-sight observation with images displayed on the screen. This effectively overcomes the problems of inconvenient movement of cab-less wide-body dump trucks during malfunctions or maintenance, and the inability of operators to obtain information about the vehicle's surrounding environment, leading to inaccurate remote control and high safety risks. It significantly improves the safety, accuracy, and overall reliability of remote control operations.

[0053] In this example implementation, the real-time environmental image can be converted into a signal, and the converted real-time environmental image can be sent to the remote control terminal through a switch.

[0054] Signal conversion refers to the format adaptation processing of acquired real-time environmental image data. Specifically, an Ethernet-to-CAN module can be used to convert the acquired image data into signals before sending it to the remote control terminal via a switch. A switch is a network device used to forward data packets in an ad hoc network. It can be implemented using an Ethernet switch or a wireless switch, and its purpose is to optimize data transmission paths and reduce the impact of network interference and congestion through dynamic routing management functions.

[0055] First, by converting the real-time environmental image signal, the original image data is adapted to the transmission characteristics of the ad hoc network, ensuring data format compatibility. Then, the converted image data is transmitted through a switch, utilizing the switch's dynamic routing mechanism to adjust the data flow path in real time. This effectively reduces the negative impact of signal interference and network fluctuations on the transmission process, forming a complete image transmission optimization mechanism. This approach effectively avoids delays, image loss, and quality degradation during image transmission, further ensuring that operators can perform safe and precise remote control operations based on clear and continuous environmental images.

[0056] Figure 3 A schematic diagram of a wireless image transmission remote control system according to a specific embodiment of the present disclosure is shown, the wireless image transmission remote control system comprising the following components: Transmitting terminal: radio, antenna, handheld remote control with display screen (with built-in batteries).

[0057] Receiving terminals: radio, antenna, high-definition network camera, switch, Ethernet to CAN module.

[0058] Repeater station: Radio station (add if necessary, otherwise do not add, depending on the actual situation).

[0059] In practical applications, this data transmission method matches the remote control terminal with the ad hoc network where the vehicle terminal is located. Utilizing the dynamic networking characteristics of the ad hoc network, it achieves flexible access, avoiding reliance on 5G private networks or fixed infrastructure, and ensuring reliable connections in complex scenarios such as mines. After successful matching, the link status of the ad hoc network and the initial status of the vehicle terminal are acquired and displayed, providing operators with real-time feedback on network connection quality and decision-making basis for vehicle operation status, thereby assessing the feasibility of remote control operations and mitigating potential risks. Furthermore, a transmission start command is sent to the vehicle terminal to activate the image transmission function based on the ad hoc network, triggering the vehicle-side image acquisition module to operate. Thus, real-time environmental images around the vehicle terminal are acquired and displayed through the image transmission function, enabling operators to perform precise remote control operations by simultaneously combining line-of-sight observation with the display screen image. This method effectively solves the problem of inconvenient movement of cab-less wide-body dump trucks during malfunctions or maintenance. Operators can remotely control the vehicle from a safe location without having to approach it, significantly reducing personal safety risks. At the same time, the acquisition and display of real-time environmental images provides intuitive information about the dynamic environment around the vehicle, overcoming the shortcomings of lacking environmental information in traditional point-to-point remote control, realizing safe and precise remote control operation, and improving the overall convenience and reliability of operation.

[0060] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.

[0061] Furthermore, this disclosure also provides a data transmission device for use in a remote control terminal.

After successful matching, it can obtain and display the link status of the ad hoc network and the initial status of the vehicle terminal. The start command sending module 420 can be used to send a transmission start command to the vehicle terminal so that the vehicle terminal can activate the image transmission function based on the self-organizing network. The environmental image acquisition module 430 can be used to acquire and display real-time environmental images around the vehicle terminal sent by the vehicle terminal through the image transmission function.

[0065] Furthermore, this disclosure also provides a data transmission device applied to a vehicle terminal.

Wherein: The initial state sending module 510 can be used to send the initial state of the vehicle terminal to the remote control terminal after the remote control terminal and the self-organizing network where the vehicle terminal are located have been successfully matched. The transmission function activation module 520 can be used to receive the transmission start command sent by the remote control terminal and activate the image transmission function based on the self-organizing network on the vehicle terminal. The environmental image transmission module 530 can be used to collect real-time environmental images around the vehicle terminal through the vehicle-mounted camera and send the real-time environmental images to the remote control terminal through the image transmission function.
