[0058] See attached Figure 1 The communication system of the present invention includes a vehicle-mounted wireless transmission unit, a multi-mode communication module and a network selection module, and is characterized in that:

[0059] The vehicle-mounted wireless transmission unit is wirelessly connected to the multi-mode communication module, the multi-mode communication module identifies and connects to multiple communication networks, and performs data transmission with the corresponding communication network according to the instructions of the network selection module;

[0066] Get real-time network status parameter information;

[0067] Based on the real-time network status parameter information, each network is evaluated according to a preset priority rule, and a network is selected according to the evaluation result;

[0068] Generate selection and switching instructions and send them to the multi-mode communication module,

[0069] The real-time network status parameters of the connected communication network are obtained through the multi-mode communication module.

[0070] The network selection module monitors the real-time network status parameters in real time, triggers the network switching mechanism according to the preset network switching conditions, generates a switching instruction and sends it to the multi-mode communication module.

[0071] Wherein, the communication system further includes a fault diagnosis module:

[0072] When a communication failure occurs, the fault is located and diagnosed, and a fault information record and diagnosis report are generated.

[0073] Specifically,

[0074] 1. Multi-mode communication module.

[0075] The multi-mode communication module identifies and connects to multiple communication networks, and performs data transmission with the corresponding communication network according to the connection instruction of the network selection module.

[0076] In this embodiment, the multiple communication networks include: GSM-R, LTE-R and 5G networks.

[0077] The multi-mode communication module can intelligently identify and connect to the GSM-R, LTE-R or 5G network, and transmit data through the corresponding interface. In this embodiment, when the multi-mode communication module communicates with the GSM-R network, data is transmitted through the Igsm-R interface; when the multi-mode communication module communicates with the LTE-R network, data is transmitted through the Uu interface; when the multi-mode communication module communicates with the 5G network, it communicates with the 5G base station through the interface for 5G.

[0078] The multi-mode communication module is also configured to obtain real-time network status parameters of the connected communication network.

[0079] 2. Network selection module.

[0080] In order to achieve seamless switching, the network selection module monitors network status, signal quality, data transmission rate and other network status parameters in real time according to the network selection and switching algorithm, intelligently selects the best network, generates network selection and switching instructions and sends them to the multi-mode communication module. It ensures that the train switches seamlessly between different network coverage areas and maintains communication continuity.

[0081] In this embodiment, the network selection module monitors the network status parameters in real time, selects a network according to a preset priority rule, and generates an instruction to send to the multi-mode communication module, including:

[0082] Get real-time network status parameter information;

[0083] Based on the real-time network status parameter information, each network is evaluated according to a preset priority rule, and a network is selected according to the evaluation result;

[0084] Generate selection and switching instructions and send them to the multi-mode communication module.

[0085] (1) Network selection and switching algorithm.

[0086] The network selection and switching algorithms are designed to ensure that trains switch seamlessly and efficiently between different communication networks, including:

[0087] Collect real-time network status parameter information from various available networks (such as GSM-R, LTE-R, 5G, etc.), including network coverage, signal strength, frequency band, network load, etc. These network status parameter information are obtained in real time through the communication module and stored in the system database;

[0088] Evaluate these networks according to preset priority rules or policies, including but not limited to: evaluate based on network performance parameters (such as data transmission rate, delay), cost, security and other factors. For example, if the signal strength and data transmission rate of the 5G network are better than those of the LTE-R network, the 5G network is preferred.

[0089] According to the evaluation results, the optimal network generation selection and switching instructions are sent to the multi-mode communication module.

[0090] The communication module performs data transmission with the corresponding communication network according to the instruction.

[0091] In this embodiment, the network selection module is further configured to:

[0092] The real-time network status parameters are monitored in real time, a network switching mechanism is triggered according to a preset network switching condition, and a switching instruction is generated and sent to the multi-mode communication module.

[0093] The preset network switching conditions include, but are not limited to: the performance of the current network is degraded (such as weakened signal strength, reduced data transmission rate), or there is a network with a better evaluation result.

[0094] During the train's travel, the network selection module continuously monitors the performance parameters of the current network and the availability of other identifiable networks in the surrounding area. If the performance of the current network deteriorates (such as weakened signal strength and reduced data transmission rate), or a better network appears, the network switching mechanism is triggered, and a switching instruction is generated and sent to the multi-mode communication module. The communication module switches to the corresponding network for data transmission according to the switching instruction.

[0095] During the switching process, in order to ensure the continuity and integrity of data transmission, unsent data can be cached before switching the network; after switching the network, the data can be resent to ensure that they are correctly received and processed.

[0096] (2) Real-time monitoring of network status, signal quality, data transmission rate and other parameters.

[0097] Through the multi-mode communication module, connections are established with various networks, and real-time information from these networks is obtained. This information includes network coverage, signal strength, frequency band, data transmission rate, etc. Then, this information is processed and analyzed through the network selection module. For example, the system will quantify the signal strength to obtain the specific value of the signal strength; at the same time, the data transmission rate is monitored and counted to obtain the average, maximum, minimum and other parameters of the data transmission rate. The processed information is stored in the database for subsequent analysis and use. This information can be used to evaluate the performance and quality of the network and trigger the network switching mechanism.

[0098] In this embodiment, the real-time monitoring results can also be displayed to the user through a graphical interface or logs, etc., so that the user can intuitively understand the performance and status of the current network, as well as possible problems.

[0099] In this embodiment, the system further includes a link control unit for managing the communication link between the system and the wireless transmission module to ensure the correct transmission and reception of data. The link control unit implements data forwarding and processing through an interface with the wireless transmission unit.

[0100] In this embodiment, the system further includes a fault tracking module. When a communication fault occurs, the fault tracking module can be used to track events, quickly determine the fault point and cause, and provide fault information records and diagnostic reports to help maintenance personnel quickly locate and solve the problem.

[0101] In this embodiment, when a communication failure is detected, such as network disconnection, increased data transmission error rate, sharp drop in signal quality, etc., the fault tracking module will be triggered immediately. The trigger condition can be a preset network parameter threshold or condition. When the preset trigger condition is met, the fault tracking module enters the fault tracking and diagnosis process.

[0102] The fault tracing and diagnosis process includes:

[0103] Collect fault information, including communication logs, network status, signal quality data, data transmission rate, error codes, etc., and store the fault information in a database for subsequent analysis and diagnosis;

[0104] Use advanced algorithms and data analysis tools to analyze fault information and locate the specific link or component where the fault occurs by comparing the data of normal state and fault state;

[0105] Further analyze the cause of the fault, such as hardware failure, software error, network problem or configuration error. The fault tracking module can also verify and confirm the accuracy of the fault cause by simulating the fault scenario.

[0106] Generate a detailed fault report, including the fault time, location, impact range, fault cause, repair suggestions, etc., and store the fault report in the system log for subsequent query and reference;

[0107] Provide troubleshooting suggestions, such as replacing faulty hardware, updating software versions, adjusting network configurations, etc.

[0108] In this embodiment, the fault tracking module can also provide remote fault repair guidance to help maintenance personnel quickly solve the problem.
