Specific embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Some concepts that may be involved in the embodiments of the present disclosure are briefly introduced below.

[0033] GSM (Global System for Mobile Communications): A widely used mobile communication standard globally to achieve seamless roaming between different countries.

[0034] RLTE (Railway Long Term Evolution): A wireless communication technology specifically designed for railway communication systems. It is based on LTE (Long Term Evolution) technology and optimized for the special needs of the railway industry. The purpose is to provide efficient, reliable, and secure data transmission services for the railway system to support applications such as train operation control, passenger information services, and railway maintenance.

[0035] R5G: Railway 5G, a fifth-generation mobile communication technology specifically designed for the railway industry, combines the advantages of 5G such as high speed, low latency, and large connection numbers, providing a more efficient, safer, and smarter solution for railway transportation.

[0036] The embodiments of the present disclosure provide a train integrated communication and positioning method. Refer to Figure 1 , Figure 1 A flowchart of a train integrated communication and positioning method provided by the embodiments of the present disclosure can solve the problems of deficiencies in aspects such as communication stability, positioning accuracy and real-time performance, system compatibility and scalability in complex application scenarios such as extreme weather, high-speed operation, and tunnel and other enclosed environments, improve the safety and efficiency of train operation, realize the real-time transmission and processing of positioning information, and improve the real-time performance and accuracy of positioning. The method includes the following steps: S100. Obtain multiple communication signals between the train and the ground control center according to multiple communication technologies, and the multiple communication technologies correspond to the multiple communication signals one by one.

[0037] In this embodiment, multiple communication technologies include Global System for Mobile Communications (GSM), Railway Long-Term Evolution (RLTE), and Railway 5G (R5G). GSM is mainly responsible for providing basic communication services when the train is running in remote areas or areas with poor network coverage, supporting voice calls and data transmission, and ensuring the basic connection between the train and the ground control center. RLTE can provide higher data transmission rates and lower latency, and is particularly suitable for application scenarios that require real-time communication such as train operation monitoring and dispatching command, and can maintain a stable communication connection when the train is running at high speed. R5G can provide high data transmission rates, ultra-low latency, and large-capacity connection capabilities, and support high-speed data transmission between the train and the ground control center, as well as vehicle-to-vehicle communication between trains, providing the possibility for more intelligent and efficient train operation management.

[0038] S200. Switch the communication technology according to the signal quality of multiple communication signals to obtain the target communication signal with the highest signal quality.

[0039] In this embodiment, Global System for Mobile Communications (GSM), Railway Long-Term Evolution (RLTE), and Railway 5G (R5G) can be switched and complemented with each other to ensure that the communication between the train and the ground control center remains unobstructed under complex environmental conditions. When switching, first obtain the signal quality of each communication signal to monitor the signal quality of each communication technology in real time. The signal quality includes indicators such as signal strength, stability, and latency. Then switch the communication technology based on the signal quality under the preset switching strategy and rules to obtain the target communication signal with the highest signal quality. It should be noted that during the process of switching the communication technology, data synchronization is performed through buffer technology and data retransmission mechanism to ensure data integrity during the switching process.

[0040] Exemplarily, when switching the communication technology, the optimal communication technology is dynamically selected for communication according to the preset switching strategy and priority rules. For example, when the 5G signal is strong and stable, the R5G technology is preferentially used; when the 5G signal is poor, it is automatically switched to the RLTE technology; if the RLTE signal is also unstable, the GSM technology is enabled as a backup.

[0041] S300. Obtain the position signal of the train.

[0042] In this embodiment, first, high-precision global positioning in an open environment is achieved based on the Beidou satellite navigation system. By receiving the signals of Beidou satellites and parsing position information such as the longitude and latitude of the train, the longitude and latitude data of the train are obtained. Then, the real-time positioning data of the train are calculated based on the 5G base station signals. When the train is in a closed environment such as a tunnel, by receiving the signals transmitted by the 5G base stations and using parameters such as the time difference and phase difference of signal transmission, combined with advanced algorithms, the real-time positioning data of the train are calculated. Finally, the train position signal is generated based on the longitude and latitude data and the real-time positioning data of the train.

[0043] S400. Perform fusion processing based on the target communication signal and the position signal to generate the communication positioning information of the train.

[0044] In this embodiment, various data transmitted by communication technologies such as GSM, RLTE, and R5G and the Beidou satellite navigation system and 5G base station positioning are fused and processed to generate complete information on the train operation status. This information includes the speed, position, direction, signal status, fault alarm, etc. of the train. In the data fusion process, advanced algorithms and technologies are adopted to ensure that data from different sources can be accurately and efficiently integrated together to form a consistent and easy-to-understand description of the train operation status. In addition, to ensure the accuracy and reliability of the data, a powerful data verification and error correction function is also available.

[0045] Exemplarily, verification is performed on the format, numerical range, consistency, data type, data point missing, and data fault aspects based on the communication positioning information of the train. Then, the train position signal is transmitted to the ground control center in real time according to the data transmission protocol and encryption technology.

[0046] Exemplarily, in terms of format verification, check whether the format of the data conforms to the expectation. For example, check the length of the data packet, the arrangement order of the fields, etc. Numerical range verification: Check whether the numerical range of the data is reasonable. For example, check whether the speed of the train is within the physically possible range. In terms of consistency verification, compare the data from different modules or sensors to ensure their consistency. For example, if there are significant differences between the position information reported by the positioning module and the base station position information reported by the communication module, this sub-module will trigger further checks or alarms.

[0047] Exemplarily, in terms of data error correction, multiple strategies are adopted to process the error data. For example, data type duplicate verification: For suspected error data, this sub-module will try to obtain the same type of data from other modules or sensors for comparison to confirm the accuracy of the data. In terms of the interpolation algorithm for missing data points, for missing data points, this sub-module will use the information of adjacent data points for interpolation calculation to estimate the missing data values.

[0048] Exemplarily, in terms of data failures, fault isolation is adopted. If a certain module or sensor continuously provides incorrect data, it will be marked as a fault state, and its subsequent data inputs will be automatically ignored to ensure the accuracy of the overall data.

[0049] For example, during a train operation, when using the Beidou satellite navigation system or 5G base station signals, an abnormally high position coordinate is suddenly reported for some reason. At this time, data fusion and processing will immediately detect this anomaly, and by comparing with data from other steps (such as communication technologies), it is found that the position coordinate does not match the actual situation. Subsequently, this step will trigger an error correction mechanism, attempting to obtain the correct position information from other reliable sensors or data sources, or estimating a reasonable position coordinate using an interpolation algorithm. At the same time, this step will also record this abnormal situation and report it to the ground control center for timely taking necessary measures.

[0050] Based on the above method, an embodiment of the present disclosure also provides a train integrated communication and positioning system 2000 corresponding to the above method, as Figure 2 shown Figure 2 is a block diagram of a train integrated communication and positioning system provided by an embodiment of the present disclosure. The system includes a communication module 210, a signal switching module 220, a positioning module 230, a data processing module 240, and a power management module 250. The communication module 210 is used to obtain multiple communication signals between the train and the ground control center according to multiple communication technologies, and multiple communication technologies correspond to multiple communication signals one by one; the signal switching module 220 is used to switch communication technologies according to the signal quality of the multiple communication signals to obtain a target communication signal with the highest signal quality; the positioning module 230 is used to obtain the position signal of the train; the data processing module 240 is used to perform fusion processing based on the target communication signal and the position signal to generate the communication and positioning information of the train. The power management module 250 is used to provide a stable and reliable power supply for each communication technology module to ensure the continuous operation of the system.

[0051] In this embodiment, on the one hand, the system integrates multiple communication technologies, including GSM, RLTE, R5G, and the Beidou satellite navigation system, which can achieve the complementarity and redundancy of multiple communication methods, improving the stability and reliability of communication. Under complex environmental conditions, even if a certain communication technology fails, other communication technologies can still maintain smooth communication, ensuring the safety and stability of train operation. On the other hand, by integrating the Beidou satellite navigation system, high-precision global positioning can be achieved in open environments. When the train is running at high speed or in a closed environment such as a tunnel, the 5G signal transmitted by the base station is received by the train. By using parameters such as the time difference and phase difference of signal transmission and combining advanced algorithms, the real-time position of the train can be accurately calculated. At the same time, combined with high-speed communication technologies such as 5G, real-time transmission and processing of positioning information can be achieved, improving the timeliness and accuracy of positioning. On the other hand, by adopting a modular design, it is convenient to integrate multiple communication and positioning technologies, realizing information interconnection and sharing between different train control systems, thereby enhancing system compatibility and expandability. In addition, with the continuous development of technology, new functions can be easily upgraded and expanded to meet the future requirements of higher-speed and more intelligent train operation.

[0052] In some embodiments, the communication module includes a GSM sub-module 211, an RLTE sub-module 212, an R5G sub-module 213, and a communication protocol processing sub-module 214. The GSM / RLTE / R5G sub-modules integrate three communication technologies, GSM, RLTE, and R5G, which can switch and complement each other to ensure that the communication between the train and the ground control center remains smooth under complex environmental conditions. The communication protocol processing sub-module is responsible for processing the communication protocol conversion between different communication technologies to ensure the correct transmission and parsing of data.

[0053] In some embodiments, the signal switching module 220 includes a signal quality detection sub-module 221, an intelligent decision-making sub-module 222, and a seamless switching and data synchronization sub-module 223. The signal quality detection sub-module 221 monitors the signal quality of each communication technology sub-module in real time, including indicators such as signal strength, stability, and latency. Based on the data provided by the signal quality detection module, the intelligent decision-making sub-module 222 will dynamically select the optimal communication technology module for communication according to the preset switching strategy and priority rules. For example, when the 5G signal is strong and stable, the 5G module is preferentially used; when the 5G signal is poor, it automatically switches to the LTE-R module; if the LTE-R signal is also unstable, the GSM module is enabled as a backup. The seamless switching and data synchronization sub-module 223 is responsible for ensuring the seamless transmission and synchronization of data when switching between communication technology modules, avoiding data loss or interruption. It uses advanced buffering technology and data retransmission mechanisms to ensure data integrity during the switching process.

[0054] In some embodiments, the positioning module 230 includes a Beidou satellite navigation sub-module 231 and a 5G base station positioning sub-module 232. The Beidou satellite navigation sub-module 231 utilizes the Beidou satellite navigation system to achieve high-precision global positioning in open environments, can receive signals from Beidou satellites, and parse position information such as the longitude and latitude of the train. The 5G base station positioning sub-module 232 is used when the train is in a closed environment such as a tunnel. By receiving signals transmitted by 5G base stations and using parameters such as time difference and phase difference of signal transmission, combined with advanced algorithms, it calculates the real-time position of the train.

[0055] In some embodiments, the data processing module 240 includes a data fusion and processing sub-module 241 and a real-time transmission sub-module 242. The data fusion and processing sub-module 241 is responsible for fusing and processing various types of data transmitted by the communication module 210 (including communication sub-modules such as GSM, RLTE, R5G, etc.) and the positioning module 230 (such as the Beidou satellite navigation system) to generate complete information on the train operation status. The real-time transmission sub-module 242 transmits the processed data to the ground control center in real time, providing strong support for the safety and stability of train operation. At the same time, it adopts an efficient data transmission protocol and encryption technology to ensure the real-time, integrity, and security of the data.

[0056] In some embodiments, the power management module 250 includes a power supply and protection sub-module 251 and an energy consumption management sub-module 252. The power supply and protection sub-module 251 provides a stable and reliable power supply for the entire device and has protection functions such as overvoltage and overcurrent to ensure the normal operation of the device in harsh environments. The energy consumption management sub-module 252 intelligently adjusts the energy consumption of each module according to the actual usage of the device to achieve the goal of energy conservation and consumption reduction.

[0057] In some other embodiments, the system further includes a controller 260. As the core of the entire system, the controller is responsible for coordinating the work between each module to implement an intelligent switching and supplement mechanism.

[0058] Through the above design, a train communication and positioning integrated system integrating GSM / LTE-R / 5G / Beidou is realized. This system can intelligently select the optimal communication technology for communication according to the train operation environment and conditions, thereby ensuring the stability and efficiency of train communication and positioning.
