[0024] Long and large-scale heavy-duty trucks are important tools in modern logistics and transportation, and it is crucial to ensure the safety and efficiency of their operation. Vehicle-to-ground communication technology, that is, the communication between the truck and the ground control center, allows the ground control center to monitor the running status of the truck through real-time vehicle-to-ground communication, and promptly grasp the speed, location and cargo status of the truck. Traditional vehicle-to-ground communication systems usually rely on dedicated communication infrastructure, such as radio communication systems. These systems are not only expensive to build, but also complex to maintain, resulting in increasing operating costs. There is a technical problem in this field on how to conduct vehicle-to-ground communication for long and large-scale heavy-duty trucks.

[0025] In order to solve the above-mentioned technical problem of how to carry out vehicle-to-ground communication for long and large formations of heavy-duty trucks, the present invention proposes a communication method, device, equipment, medium and product for long and large formations of heavy-duty trucks. The implementation details of the present invention are described in detail below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0026] Embodiment 1

[0027] Figure 1 is a flow chart of a communication method for a long marshaled heavy-duty truck provided in an embodiment of the present application, such as Figure 1As shown, in the technical solution of this embodiment, a communication method for a long and large-sized heavy-loaded truck is provided, and the method includes: S100, collecting the position data of the long and large-sized heavy-loaded truck; S200, judging whether the long and large-sized heavy-loaded truck is in a tunnel area based on the line data and position data of the long and large-sized heavy-loaded truck; S300, when the long and large-sized heavy-loaded truck is not in the tunnel area, performing vehicle-to-ground communication based on the vehicle-mounted 5G communication module.

[0028] How to achieve effective vehicle-ground communication during the operation of long and large-scale heavy-loaded trucks. In railway transportation, long and large-scale heavy-loaded trucks have a wide driving range and a complex communication environment. For example, in open areas, traditional communication methods are prone to problems such as unstable signals and low transmission rates. They cannot meet the transmission needs of large amounts of data such as real-time monitoring of truck location, speed, and cargo status, affecting transportation scheduling and safety management. If the truck location data cannot be accurately collected and stable communication cannot be established based on this, it will be difficult for the ground control center to effectively control the operating status of the truck. There are technical problems in this field that lead to low transportation efficiency and increased safety hazards due to poor communication.

[0029] In the technical solution of this embodiment, firstly, the position data of long and large-scale heavy-duty trucks are collected in real time through high-precision positioning devices, such as the global positioning system GPS, the Beidou satellite positioning system, and the positioning method based on 5G. These positioning devices are installed at the preset position of the truck and can accurately obtain real-time position information. Then, based on the line data of the truck and the collected position data, it is judged whether the truck is in the tunnel area. When it is determined that the truck is not in the tunnel area, vehicle-to-ground communication is performed based on the on-board 5G communication module. The on-board 5G communication module has high bandwidth and low latency characteristics, and can quickly transmit large amounts of data to meet the needs of real-time monitoring and rapid response. The line data contains detailed information such as the location and length of the tunnel, which is used to compare with the real-time position data to determine the area where the truck is located.

[0030] The technical solution of this embodiment can accurately grasp the location information of the truck by collecting location data through high-precision positioning equipment. The area where the truck is located is determined based on the line data and location data. In non-tunnel areas, the on-board 5G communication module is used for communication, and its high bandwidth and low latency advantages can be used to achieve real-time and efficient transmission of a large amount of data such as the truck's location, speed, and cargo status. For example, the ground control center can obtain the speed of the truck in real time through this communication, and adjust the transportation scheduling in time to avoid the impact of abnormal speed on the transportation plan. At the same time, it can also understand the cargo status in real time and ensure the safe transportation of cargo, which greatly improves the transportation efficiency and safety and enhances the intelligent management level of railway transportation.

[0031] Embodiment 2

[0032] Based on the above embodiments, S300, when a long and large-sized heavy-loaded truck is not in a tunnel area, vehicle-to-ground communication is performed based on the vehicle-mounted 5G communication module, including: when a long and large-sized heavy-loaded truck is not in a tunnel area, vehicle-to-ground communication is performed based on the vehicle-mounted 5G communication module arranged at the front of the vehicle or vehicle-to-ground communication is performed based on the vehicle-mounted 5G communication module arranged at the rear of the vehicle.

[0033] When a long and large formation of heavy-loaded freight cars is not in the tunnel area, how to implement vehicle-to-ground communication to ensure the reliability and stability of communication. In actual railway transportation, when a freight car is traveling in a non-tunnel area, such as a plain or wilderness, if it only relies on a single on-board communication device, it is easy to cause communication interruption or data transmission error due to problems such as communication module failure or signal interference. For example, if only the on-board communication module of the front of the car is used, once a hardware failure occurs in the module, vehicle-to-ground communication will be blocked, and the ground control center will not be able to obtain real-time information about the freight car, affecting the monitoring and scheduling of the freight car, and further affecting the smooth progress of the entire transportation process. In this field, there are technical problems such as a single vehicle-to-ground communication method in non-tunnel areas and insufficient reliability.

[0034] In the technical solution of this embodiment, when it is determined that a long and large formation of heavy-duty trucks is not in the tunnel area, two communication options are provided, namely, vehicle-to-ground communication based on the on-board 5G communication module set at the front of the vehicle or vehicle-to-ground communication based on the on-board 5G communication module set at the rear of the vehicle. The on-board 5G communication module has the characteristics of high bandwidth and low latency, and can quickly and stably transmit key information such as the location, speed, and cargo status of the truck. By setting up on-board 5G communication modules at the front and rear of the vehicle, the redundancy of communication is increased. When one of the modules fails or is interfered with, the other module can continue to work to ensure the continuity of vehicle-to-ground communication.

[0035] The technical solution of this embodiment significantly improves the reliability of vehicle-ground communication by setting up on-board 5G communication modules at the front and rear of the vehicle respectively, and selecting one of them for communication when not in the tunnel area. For example, when a truck is traveling in an open plain area, if the on-board 5G communication module at the front of the vehicle has communication abnormalities due to strong electromagnetic interference nearby, since the long-formed heavy-loaded truck is several kilometers long, it can automatically switch to the on-board 5G communication module at the rear of the vehicle with less impact to continue vehicle-ground communication. In this way, the ground control center can continuously obtain real-time operation data of the truck, such as speed, location, etc., so as to make accurate scheduling decisions in a timely manner, ensure the smooth progress of transportation tasks, reduce transportation delays caused by communication problems, and improve the overall efficiency and safety of railway transportation.

[0036] Embodiment 3

[0037] On the basis of the above embodiments, when a long and large-sized heavy-loaded truck is not in a tunnel area, vehicle-to-ground communication is performed based on the on-board 5G communication module arranged at the front of the vehicle or based on the on-board 5G communication module arranged at the rear of the vehicle, including: when the vehicle-to-ground communication duration of the on-board 5G communication module arranged at the front / rear of the vehicle reaches a preset duration, switching to the on-board 5G communication module arranged at the rear / front of the vehicle for vehicle-to-ground communication.

[0038] When a long and large formation of heavy-loaded trucks is not in the tunnel area, how to ensure that the on-board 5G communication modules at the front and rear of the truck can complete the communication task and always be in a normal state. In actual operation, if a communication module continues to work for a long time, it is easy to cause performance degradation or even failure due to overheating. For example, when a truck is traveling long distances in a non-tunnel area, if the on-board 5G communication module at the front of the truck is used for communication, after several hours or even longer, the module is prone to data transmission errors or communication interruptions due to overheating. Once the communication module fails, the ground control center will not be able to obtain key information such as the location and speed of the truck in a timely manner, affecting transportation scheduling and safety management. There is a technical problem in this field that the on-board 5G communication module is prone to failure after working for a long time, affecting communication.

[0039] In the technical solution of this embodiment, when the vehicle-to-ground communication duration of the on-board 5G communication module arranged at the front / rear of the vehicle reaches the preset duration, it is switched to the on-board 5G communication module arranged at the rear / front of the vehicle for vehicle-to-ground communication. The preset duration can be set according to actual conditions, such as 1 minute, 5 minutes, 10 minutes, 30 minutes, etc. Through this communication duration switching mechanism, a certain communication module is prevented from working continuously for a long time. When a module works for a preset duration, the system automatically switches to another module, so that the previously working module has time to dissipate heat and restore performance. The on-board 5G communication module is responsible for vehicle-to-ground communication in non-tunnel areas, and transmits various types of truck data, such as location, speed, cargo status and other information to the ground control center.

[0040] The technical solution of this embodiment effectively ensures the normal operation of the on-board 5G communication module by setting a communication duration switching mechanism. For example, when a truck is traveling in a non-tunnel area, the on-board 5G communication module at the front of the vehicle first performs vehicle-to-ground communication. When the preset duration of 10 minutes is reached, it automatically switches to the on-board 5G communication module at the rear of the vehicle. As a result, the communication module at the front of the vehicle has time to rest and dissipate heat, reducing the risk of failure due to overheating. Moreover, during the switching process, the ground control center can still continue to obtain real-time data of the truck, such as speed, location, etc., to ensure that transportation scheduling is not affected. At the same time, through this switching, it is also possible to detect in time whether there is a potential fault in the communication module. If the new module cannot communicate normally after switching, it can be discovered and measures can be taken in time, further improving the reliability and stability of vehicle-to-ground communication and ensuring the safe and efficient conduct of railway transportation.

[0041] Embodiment 4

[0042] Based on the above embodiments, the method also includes: S400, when a long and large-sized heavy-loaded truck is in a tunnel area, selecting a vehicle-mounted 5G communication module or a vehicle-mounted private network communication module for vehicle-ground communication according to the ratio of the length of the long and large-sized heavy-loaded truck to the length of the tunnel.

[0043] When long and large formations of heavy-loaded trucks are in the tunnel area, how to achieve stable and reliable vehicle-to-ground communication. In railway transportation, the tunnel area has a special environment, with serious signal obstruction and interference, and it is difficult to ensure the communication quality with traditional communication methods. For example, when a truck enters a tunnel, due to the shielding effect of the tunnel wall on the signal, the 5G signal is easily greatly attenuated, resulting in data transmission interruption or serious delay. At this time, if the appropriate communication method cannot be switched in time, the ground control center will not be able to grasp the running status of the truck in the tunnel in real time, such as position, speed, cargo status, etc., which may easily cause safety hazards and affect transportation efficiency. In this field, there are technical problems that vehicle-to-ground communication in the tunnel area is greatly affected by the environment and has poor stability.

[0044] In the technical solution of this embodiment, when it is determined that a long and large-sized heavy-duty truck is in a tunnel area, a vehicle-mounted 5G communication module or a vehicle-mounted private network communication module is selected for vehicle-to-ground communication according to the ratio of the length of the long and large-sized heavy-duty truck to the length of the tunnel. The vehicle-mounted 5G communication module has the advantages of high speed and large capacity, but the signal is susceptible to interference in a tunnel environment where a 5G base station is not deployed. The vehicle-mounted private network communication module has strong anti-interference ability and stability. By comparing the ratio of the length of the truck to the length of the tunnel, it is determined which communication module is more appropriate. If the ratio is greater than the preset threshold, it means that at least one end of the truck is likely to be outside the tunnel and it is easy to receive a better 5G public network signal. At this time, the vehicle-mounted 5G communication module is selected; if the ratio is less than or equal to the preset threshold, the truck is likely to be in the tunnel as a whole, and the 5G signal is severely attenuated, so the vehicle-mounted private network communication module is selected.

[0045] The technical solution of this embodiment effectively overcomes the adverse effects of the tunnel environment on vehicle-to-ground communication by selecting a suitable communication module based on the ratio of the truck length to the tunnel length. For example, when a truck enters a shorter tunnel and the ratio of its length to the tunnel length is greater than the preset threshold value 1, at least one end of the front or rear of the truck is outside the tunnel. At this time, the vehicle-to-ground communication is carried out through the on-board 5G communication module, which can take advantage of its high speed and large capacity to quickly transmit the real-time data such as the position and speed of the truck in the tunnel to the ground control center. When the truck enters a longer tunnel and the ratio of its length to the tunnel length is less than or equal to 1, the on-board private network communication module is selected. With its strong anti-interference ability and stability, the reliability of vehicle-to-ground communication is guaranteed, so that the ground control center can continuously monitor the running status of the truck in the tunnel, promptly discover and deal with problems that arise, greatly improving the stability of vehicle-to-ground communication in the tunnel area, and ensuring the safety and efficiency of railway transportation in complex environments.

[0046] Embodiment 5

[0047] On the basis of the above embodiments, S400, when a long and large heavy-duty truck is in a tunnel area, a vehicle-mounted 5G communication module or a vehicle-mounted private network communication module is selected for vehicle-to-ground communication according to the ratio of the length of the long and large heavy-duty truck to the length of the tunnel, including: when the ratio of the length of the long and large heavy-duty truck to the length of the tunnel is greater than a preset threshold, vehicle-to-ground communication is performed through the vehicle-mounted 5G communication modules arranged at the front and rear of the vehicle.

[0048] How to achieve efficient and stable vehicle-to-ground communication when a long and large marshaled heavy-loaded truck is in a tunnel area and the ratio of the truck length to the tunnel length is greater than a preset threshold. In actual tunnel transportation scenarios, when the length of the truck exceeds the length of the tunnel, although at least one end of the front or rear of the vehicle can easily receive a certain signal outside the tunnel, there is still a signal interference problem in the tunnel. For example, if communication is only based on a single communication module at the front or rear of the vehicle, it is easy to cause unstable signal transmission due to the complex environment in the tunnel, and it is impossible to quickly and accurately transmit the truck's operating data in the tunnel, such as cargo status, car temperature and other information to the ground control center, affecting the comprehensive monitoring of the truck and transportation safety management. In this field, there is a technical problem of unstable communication in the tunnel when the truck is longer than the tunnel.

[0049] In the technical solution of this embodiment, when the ratio of the length of a long and large marshaled heavy-duty truck to the length of the tunnel is greater than a preset threshold (for example, the preset threshold is set to 1), vehicle-to-ground communication is performed simultaneously through the on-board 5G communication modules arranged at the front and rear of the vehicle. The on-board 5G communication module has the characteristics of high bandwidth and low latency, and can quickly transmit large amounts of data. Since the length of the truck exceeds the length of the tunnel, at least one end of the front and rear of the vehicle is outside the tunnel and can receive a better 5G signal. Taking advantage of this, the on-board 5G communication modules at the front and rear of the vehicle are enabled at the same time to increase the reliability of communication and the amount of data transmission. The two modules work at the same time to complement each other's signals and reduce the risk of signal interruption due to interference in the tunnel.

[0050] The technical solution of this embodiment greatly improves the quality and efficiency of vehicle-to-ground communication by allowing the on-board 5G communication modules at the front and rear of the vehicle to work simultaneously when the ratio of the length of the truck to the length of the tunnel is greater than a preset threshold. For example, when a truck is traveling in a shorter tunnel, the length of the truck is greater than the length of the tunnel. At this time, the on-board 5G communication modules at the front and rear of the vehicle transmit data simultaneously. The ground control center can obtain detailed information about the truck in the tunnel in a more comprehensive and timely manner, such as the cargo status of each compartment, the real-time speed of the truck, etc. Even if there is a certain interference in the tunnel, the two modules work at the same time, which can ensure the stable transmission of data and avoid the lack of monitoring of the truck's operating status due to poor communication, effectively improving transportation safety and management efficiency, and ensuring the smooth progress of railway transportation in such special tunnel scenarios.

[0051] Embodiment 6

[0052] On the basis of the above embodiments, S400, when a long and large-sized heavy-loaded truck is in a tunnel area, the vehicle-mounted 5G communication module or the vehicle-mounted private network communication module is selected for vehicle-to-ground communication according to the ratio of the length of the long and large-sized heavy-loaded truck to the length of the tunnel, including: when the ratio of the length of the long and large-sized heavy-loaded truck to the length of the tunnel is less than or equal to a preset threshold, vehicle-to-ground communication is performed through the vehicle-mounted private network communication module.

[0053] How to ensure the reliability of vehicle-ground communication when a long and large marshaled heavy-loaded truck is in a tunnel area and the ratio of the truck length to the tunnel length is less than or equal to the preset threshold. In railway transportation, when the truck is basically in a long tunnel, the 5G signal is easily interfered and attenuated, and it is difficult for traditional communication methods to maintain stable communication. For example, if a truck continues to use a 5G communication module when it is traveling in a long tunnel, it is prone to frequent data transmission interruptions and serious delays. The ground control center cannot obtain key information such as the location, speed, and cargo status of the truck in a timely manner, and cannot effectively dispatch and safely manage the truck, which is easy to cause safety accidents and affect transportation efficiency. There are technical problems in this field that it is difficult to communicate in the tunnel when the truck is shorter than the tunnel.

[0054] In the technical solution of this embodiment, when the ratio of the length of a long and large marshaled heavy-duty truck to the length of the tunnel is less than or equal to a preset threshold, vehicle-to-ground communication is performed through the on-board private network communication module. The on-board private network communication module has strong anti-interference ability and stability, and is specially designed for communication needs in complex environments. When the truck is in the tunnel as a whole and the 5G signal is seriously affected by the tunnel environment, the on-board private network communication module can give full play to its advantages, overcome problems such as signal blocking and interference, and ensure data transmission between the vehicle and the ground. It can stably transmit information such as the truck's position, speed, and cargo status in the tunnel to the ground control center, ensuring real-time monitoring of the ground control center's operating status of the truck.

[0055] The technical solution of this embodiment effectively solves the communication problem of trucks in long tunnels by using an on-board private network communication module when the ratio of the truck length to the tunnel length is less than or equal to a preset threshold. For example, when a truck is traveling in a long tunnel and its length is less than the tunnel length, the 5G signal is severely attenuated or even interrupted. At this time, the on-board private network communication module starts to work and continuously and stably transmits the location information of the truck to the ground control center, so that the ground control personnel can grasp the location of the truck in the tunnel in real time for timely dispatch. At the same time, the status information of the goods on the truck, such as temperature and humidity, can also be transmitted back to ensure the safety of the goods. In this way, the reliability of vehicle-to-ground communication in the tunnel is greatly improved, and the safety and transportation efficiency of railway transportation in complex tunnel environments are improved.

[0057] Figure 2 : is a schematic diagram of a communication device for a long marshaled heavy-duty truck provided in an embodiment of the present application, such as Figure 2 As shown, in the technical solution of this embodiment, a communication device for a long and large-sized heavy-loaded truck is provided, and the device includes: an acquisition module for collecting position data of the long and large-sized heavy-loaded truck; a judgment module for judging whether the long and large-sized heavy-loaded truck is in a tunnel area based on the line data and position data of the long and large-sized heavy-loaded truck; and a communication module for performing vehicle-to-ground communication based on the on-board 5G communication module when the long and large-sized heavy-loaded truck is not in the tunnel area.

[0058] How to achieve effective vehicle-ground communication during the operation of long and large-scale heavy-loaded trucks. In railway transportation, long and large-scale heavy-loaded trucks have a wide driving range and a complex communication environment. For example, in open areas, traditional communication methods are prone to problems such as unstable signals and low transmission rates. They cannot meet the transmission needs of large amounts of data such as real-time monitoring of truck location, speed, and cargo status, affecting transportation scheduling and safety management. If the truck location data cannot be accurately collected and stable communication cannot be established based on this, it will be difficult for the ground control center to effectively control the operating status of the truck. There are technical problems in this field that lead to low transportation efficiency and increased safety hazards due to poor communication.

[0059] In the technical solution of this embodiment, firstly, the position data of long and large-scale heavy-duty trucks are collected in real time through high-precision positioning equipment, such as the global positioning system GPS, the Beidou satellite positioning system, and a 5G-based positioning device. These positioning devices are installed at the preset position of the truck and can accurately obtain real-time location information. Then, based on the line data of the truck and the collected location data, it is determined whether the truck is in the tunnel area. When it is determined that the truck is not in the tunnel area, vehicle-to-ground communication is performed based on the on-board 5G communication module. The on-board 5G communication module has high bandwidth and low latency characteristics, and can quickly transmit large amounts of data to meet the needs of real-time monitoring and rapid response. The line data contains detailed information such as the location and length of the tunnel, which is used to compare with the real-time location data to determine the area where the truck is located.

[0060] The technical solution of this embodiment can accurately grasp the location information of the truck by collecting location data through high-precision positioning equipment. The area where the truck is located is determined based on the line data and location data. In non-tunnel areas, the on-board 5G communication module is used for communication, and its high bandwidth and low latency advantages can be used to achieve real-time and efficient transmission of a large amount of data such as the truck's location, speed, and cargo status. For example, the ground control center can obtain the speed of the truck in real time through this communication, and adjust the transportation scheduling in time to avoid the impact of abnormal speed on the transportation plan. At the same time, it can also understand the cargo status in real time and ensure the safe transportation of cargo, which greatly improves the transportation efficiency and safety and enhances the intelligent management level of railway transportation.

[0069] Embodiment 9

[0070] Based on the above embodiments, this embodiment provides an application example. This application example provides a vehicle-to-ground communication device for a long-length marshaled heavy-duty truck based on the public network 5G.

[0071] Long and large marshaled heavy-duty trucks are important tools in modern logistics and transportation, and it is crucial to ensure the safety and efficiency of their operation. Vehicle-to-ground communication technology, that is, the communication between the truck and the ground control center, is an important means to ensure its normal operation. Through real-time vehicle-to-ground communication, the ground control center can monitor the operating status of the truck, keep abreast of the speed, location and cargo status of the truck, and promptly discover and deal with potential safety issues to prevent accidents. At the same time, vehicle-to-ground communication technology can also support accurate vehicle scheduling, optimize transportation routes, improve transportation efficiency, and remotely monitor vehicle health, predict maintenance needs, and extend vehicle service life.

[0072] However, with the development of technology and the increase in transportation demand, the existing vehicle-to-ground communication system has gradually exposed some problems and limitations, which to a great extent limit the further improvement of transportation efficiency and safety.

[0073] (1) Limitations of communication infrastructure

[0074] Traditional vehicle-to-ground communication systems usually rely on dedicated communication infrastructure, such as radio communication systems. These systems are not only expensive to build, but also complex to maintain, resulting in increasing operating costs. At the same time, due to the limited coverage and stability of the infrastructure, the continuity and reliability of communication are difficult to guarantee, especially in remote areas or areas with complex terrain, where the risk of communication interruption is high.

[0075] (2) Insufficient data processing and analysis capabilities

[0076] With the development of sensor technology and the Internet of Things, the amount of data generated by vehicles has increased dramatically. However, the existing vehicle-to-ground communication system has limited capabilities in data processing and analysis and is unable to cope with the challenge of large amounts of data. This not only affects the accuracy of real-time monitoring of vehicle status and fault prediction, but also limits the timeliness and effectiveness of operational decisions.

[0077] (3) Communication delay and throughput issues

[0078] In the transportation process of heavy-duty trucks, real-time and high-throughput communication is crucial to ensure transportation efficiency and safety. However, existing vehicle-to-ground communication systems often have problems with high communication delays and low throughput, which results in insufficient transmission and processing of vehicle status information, and cannot meet the needs of real-time monitoring and rapid response.

[0079] (4) Insufficient system security and anti-interference capabilities

[0080] As cyber attacks become more diverse and complex, the security of vehicle-to-ground communication systems faces severe challenges. Existing communication systems lack effective security protection measures and are vulnerable to external attacks and interference, leading to data leakage or service interruptions, posing a threat to transportation safety.

[0081] (5) Insufficient system scalability and flexibility

[0082] With the continuous changes in business needs and the emergence of new technologies, the vehicle-to-ground communication system needs to have good scalability and flexibility to adapt to future development. However, the existing systems are often closed in architecture and have poor compatibility, making it difficult to quickly adapt to new business needs and technological changes, limiting the long-term development and competitiveness of the system.

[0083] In summary, the existing vehicle-to-ground communication system for long-haul heavy-duty trucks has many problems in terms of infrastructure, data processing, communication efficiency, security, and scalability. These problems urgently need to be solved through technological innovation and system optimization to meet the needs of modern logistics and transportation for efficient, safe, and reliable communication. With the development of sensor technology and the increase in data collection needs, the existing communication system is prone to failure to meet the needs of large-scale data transmission, affecting real-time monitoring and rapid response capabilities. Especially in remote or complex terrain areas, the problem of incomplete communication coverage is more prominent. In addition, the high cost of building and maintaining dedicated communication networks has also brought a heavy economic burden to transportation companies.

[0084] With the rapid development of 5G technology, especially in the commercial application of public network 5G, its advantages such as high bandwidth, low latency and large number of connections have brought new solutions for vehicle-to-ground communication of heavy-duty trucks. Traditional heavy-duty truck communication systems usually rely on dedicated communication networks, which are not only costly, but also complex to deploy and maintain. There are also many challenges in terms of network coverage and communication stability in remote areas. The widespread application of public network 5G can effectively solve these problems and provide a more economical, reliable and efficient vehicle-to-ground communication solution. With the popularization of 5G technology, these problems are expected to be effectively solved. 5G networks have the characteristics of high bandwidth, low latency and large number of connections, which can greatly improve the performance of vehicle-to-ground communication. For example, the high speed of 5G can realize the real-time transmission of large-scale data, low latency ensures the rapid response of emergency instructions and data, and the wide network coverage can eliminate communication blind spots and ensure the stability of communication in remote areas. In addition, 5G networks have also introduced advanced technologies such as network slicing and edge computing, which provide more reliable guarantees for mission-critical communications.

[0085] The vehicle-to-ground communication device for long-haul heavy-duty trucks based on the public 5G network fully utilizes the technical advantages of 5G, solves many problems of traditional communication systems, and is expected to bring revolutionary changes to the logistics and transportation industry. This innovative solution can not only significantly reduce the communication costs of enterprises, but also greatly improve the safety, reliability and operational efficiency of heavy-duty trucks.

[0086] In the related art, the vehicle-to-ground communication system of long and large marshaled heavy-duty trucks has the following disadvantages:

[0087] 1. Technical Disadvantages:

The vehicle-mounted communication module is combined with the edge computing unit to form a distributed data processing and analysis system, while the ground communication base station, data processing center and safety monitoring module are connected through the public 5G network to form an efficient and stable vehicle-to-ground communication system for real-time data transmission and monitoring of long and large-scale heavy-duty trucks.

[0117] 2. Working principle and process description

[0118] The workflow of the present invention includes seven main steps: data collection, transmission, preprocessing, deep processing, safety monitoring, emergency response and feedback adjustment. Through this system, real-time monitoring, data analysis and emergency response capabilities of long and large-scale heavy-loaded trucks are realized.

[0119] Step 1-2: Data Collection

[0120] When the vehicle is started, the on-board communication module and sensor group are automatically activated and begin to collect key vehicle data in real time, such as location, speed, cargo status, environmental conditions, etc.

[0121] Step 3-4: Data preprocessing and transmission

[0122] The collected vehicle data is first pre-processed in the edge computing unit, including data cleaning, format conversion and preliminary analysis. The pre-processed data is sent to the ground communication base station through the vehicle-mounted 5G communication unit to ensure that the data reaches the ground system stably and quickly during transmission.

[0123] Step 5: Data analysis and processing

[0124] After receiving the data, the ground communication base station transmits the data to the data processing center through the public 5G network. In the data processing center, the data is processed by efficient cloud computing servers, and big data analysis and AI algorithms are used to conduct in-depth analysis of the vehicle's operating status, generate scheduling optimization suggestions and prediction results of potential failures.

[0125] Steps 6-8: Security Monitoring and Emergency Response

[0126] The safety monitoring module analyzes vehicle operation data in real time and monitors key parameters. If the system detects an abnormal situation, such as excessive vehicle speed or abnormal cargo status, the emergency response system will be automatically triggered. Emergency response includes sending warning messages to ground control personnel, adjusting vehicle operation plans, or triggering other emergency mechanisms to ensure the safety of the transportation process.

[0127] Steps 9-11: Instruction feedback and execution

[0128] Based on the analysis results of the data processing center and the monitoring status of the safety monitoring module, the system issues optimization instructions or adjustment suggestions to the vehicle.

The system's built-in emergency response module can take prompt measures when anomalies are detected, such as sending an early warning or automatically adjusting the vehicle's operating status to ensure the safety of the entire transportation process.

[0137] 4. Action relationships between components

[0138] The on-board communication module is responsible for transmitting the real-time data of the vehicle to the edge computing unit. After the edge computing unit performs preliminary processing on the data, it sends the data to the ground communication base station. The ground communication base station acts as a data transfer station to send the data to the data processing center. After the data processing center analyzes the data, it sends instructions to the on-board communication module when necessary. The vehicle executes these instructions and transmits the feedback results back to the ground. The safety monitoring module monitors the vehicle status in real time throughout the process to ensure the safety of transportation. This continuous closed-loop data flow and operation chain ensures the efficient and safe operation of long and large marshaled heavy-duty trucks.

[0177] Based on the fact that the present invention uses the public network 5G technology and related hardware and software architecture to realize the vehicle-ground communication of long and large marshaled heavy-duty trucks, the following technical solutions can also be used:

[0178] 1. Dedicated wireless network (such as LTE private network)

[0179] Use traditional LTE (Long Term Evolution) private networks or other dedicated wireless communication technologies to replace public 5G networks. LTE private networks can provide independent communication infrastructure to ensure high security and stability, and are particularly suitable for some scenarios with extremely high communication requirements.

[0180] Advantages: LTE private networks have high communication reliability and security, and are particularly suitable for special and sensitive application scenarios.

[0181] Disadvantages: High construction and maintenance costs, limited coverage, and easily restricted in remote areas or complex terrain. The scalability and upgrade flexibility are not as good as public network 5G, and it is not as good as 5G in terms of data throughput and low latency.

[0182] 2. Satellite communication system

[0183] Satellite communication technology, especially low-orbit satellite networks (such as Starlink), can achieve global communication and avoid the problems caused by insufficient ground communication infrastructure.

[0184] Advantages: It can achieve global communication coverage, especially for remote areas or complex terrain scenarios, satellite communication is an effective solution.

[0185] Disadvantages: Satellite communications are expensive, data transmission delays are relatively large, real-time performance and throughput are often inferior to public 5G networks, and signals are prone to instability in bad weather.

[0186] 3. Hybrid network solution

[0187] Combining multiple communication technologies, such as LTE, satellite communication and public network 5G, automatically switching network types according to different scenarios to ensure the stability and reliability of communication.

[0193] Disadvantages: The deployment of IoT devices and edge computing devices requires additional infrastructure support, and the wide-area coverage capability of this solution is not as good as the public network 5G. Especially in the case of long-distance transportation, the communication effect is likely to be inferior to the solution of the present invention.

[0194] Although the above alternatives can realize some functions of the present invention in specific scenarios, most of them have limitations in terms of coverage, data transmission speed, latency, cost and scalability. In contrast, the solution using public network 5G technology has obvious advantages in terms of wide coverage, high-speed data transmission, low latency, economy and flexible scalability. Therefore, the present invention selects public network 5G as the communication technology, which can better meet the needs of vehicle-to-ground communication of long-distance trains and heavy-duty trucks, and at the same time realize a safe, economical, scalable and efficient transportation communication solution.

[0195] Although there are other alternatives that can achieve part of the purpose of the invention, they cannot compare with the public network 5G solution of the present invention in terms of performance, cost, scalability, etc. The technical solution of the present invention has more advantages in comprehensive performance and practical application, especially in complex terrain, long-distance transportation, and real-time monitoring and scheduling, and is therefore most suitable for current needs.

[0196] This application example relates to the field of railway communication technology, and specifically to a vehicle-to-ground communication method suitable for long and large-sized heavy-loaded freight cars. The method can flexibly select a suitable communication module according to the location of the freight car and tunnel-related parameters to ensure stable and efficient vehicle-to-ground communication.

[0197] With the development of railway transportation, long and large-sized heavy-duty trucks are increasingly used. However, during their operation, vehicle-to-ground communication faces many challenges. Especially when the truck passes through the tunnel area, due to the special environment of the tunnel, such as signal blocking and interference, traditional communication methods are difficult to ensure the stability and reliability of communication. Therefore, a method is needed to intelligently select the communication method according to the location of the truck and the tunnel conditions to solve the problem of vehicle-to-ground communication of long and large-sized heavy-duty trucks.

[0198] This method aims to solve the problem of how to carry out vehicle-to-ground communication for long and large-scale heavy-loaded trucks. The specific steps are as follows:

[0199] (I) Step S100: Collecting location data of long and large trains of heavy-duty trucks

[0200] The location data of long and large trains of heavy-duty trucks are collected in real time through high-precision positioning devices (such as the Global Positioning System (GPS), the Beidou Satellite Positioning System, and 5G-based positioning methods). These positioning devices are installed at preset locations on the trucks to ensure that the real-time location information of the trucks can be accurately obtained.

[0201] (ii) Step S200: Determine whether a large and heavy-loaded truck is in a tunnel area

[0202] A comprehensive analysis is performed based on the line data of the long marshaling heavy-duty truck and the position data collected in step S100. The line data contains detailed information such as the location and length of the tunnel. By comparing the real-time position data with the tunnel position information in the line data, it is determined whether the long marshaling heavy-duty truck is in the tunnel area.

[0203] (III) Step S300: Carrying out vehicle-to-ground communication when not in the tunnel area

[0204] When it is determined that a long and large formation of heavy-duty trucks is not in the tunnel area, vehicle-to-ground communication is performed based on the on-board 5G communication module. In order to enable the on-board 5G communication modules set at the front and rear of the vehicle to take turns to perform vehicle-to-ground communication and ensure that they are all in a normal state while completing the communication task, a communication duration switching mechanism is set. When the vehicle-to-ground communication duration of the on-board 5G communication module set at the front / rear of the vehicle reaches the preset duration (for example, 1 minute, 5 minutes, 10 minutes, 30 minutes), it will automatically switch to the on-board 5G communication module set at the rear / front of the vehicle for vehicle-to-ground communication, which can avoid overheating or performance degradation caused by a certain communication module working for a long time, and can also promptly detect whether there is a fault in the communication module.

[0205] (IV) Step S400: Carrying out vehicle-to-ground communication in the tunnel area

[0206] When it is determined that the long and large marshaled heavy-loaded truck is in the tunnel area, a suitable communication module is selected for vehicle-ground communication according to the ratio of the length of the long and large marshaled heavy-loaded truck to the length of the tunnel.

[0207] When the ratio is greater than the preset threshold: the preset threshold is set to 1, for example. When the ratio of the length of a large marshaled heavy-duty truck to the length of the tunnel is greater than 1, it means that the length of the truck exceeds the length of the tunnel. At this time, at least one end of the front and rear of the truck is likely to be outside the tunnel and can receive a better 5G signal. Therefore, vehicle-to-ground communication is performed simultaneously through the on-board 5G communication modules set at the front and rear of the vehicle. This method can make full use of the high-speed and large-capacity advantages of 5G communication to ensure real-time data transmission between the vehicle and the ground.

[0208] When the ratio is less than or equal to the preset threshold: When the ratio of the length of a large marshaled heavy-duty truck to the length of the tunnel is less than or equal to 1, there will be a period of time when the truck is basically in the tunnel as a whole, and the 5G signal is prone to significant interference and attenuation. In this regard, vehicle-to-ground communication is carried out through the vehicle-mounted private network communication module. The vehicle-mounted private network communication module has strong anti-interference ability and stability, and can ensure the reliability of vehicle-to-ground communication in complex environments such as tunnels.

[0209] This method collects the location data of the truck in real time, combines the line data to determine the area where the truck is located, and flexibly selects the communication module according to the ratio of the truck length to the tunnel length, thus realizing stable vehicle-to-ground communication of long and large marshaled heavy-loaded trucks in different operating environments. In non-tunnel areas, the on-board 5G communication module is used for high-speed communication, and the normal operation of the communication module is ensured by the switching mechanism; in the tunnel area, the appropriate communication module is selected according to the specific situation, which effectively overcomes the impact of the tunnel environment on communication and improves the safety and efficiency of railway transportation.
