[0032] Example 1

[0033] Figure 1 This is a flow chart of a method for processing inter-train communication data provided by the first embodiment of the present invention. This embodiment is applicable to the case where inter-train communication data is processed during the travel of a train. The method can be applied to a communication data processing system provided in a train. The communication data processing system includes: a vehicle data acquisition unit, a position information acquisition unit, a communication log sending unit, a communication log receiving unit, and an information storage unit. The method can be executed by an inter-train communication data processing device. The inter-train communication data processing device can be implemented in the form of hardware and / or software. The inter-train communication data processing device can be configured in a terminal and / or server. Figure 1 As shown, the method includes:

[0034] S110. During the current train travel, when the first inter-vehicle communication data sent by the communication train is received through the inter-vehicle data acquisition unit, the receiving position information and the receiving timestamp corresponding to the first train are collected through the position information acquisition unit, and the receiving position information and the receiving timestamp are sent to the inter-vehicle data acquisition unit; and the corresponding signal reception information at the current moment is collected through the communication log receiving unit, and the collected signal reception information is sent to the inter-vehicle data acquisition unit.

[0035] The communication data processing system can be software installed in a train to process inter-train communication data. The communication data processing system can collect information related to communication fault analysis in real time while the train is in motion. For example, the communication data processing system can obtain, in real time, application layer communication information received by the train, application layer communication information to be transmitted, received field strength, signal-to-noise ratio, and the train's location information at various times.

[0036] The current train may be a train pre-installed with a communication data processing system. The current train may be any type of train, optionally including a heavy-haul train, freight train, or passenger train. In this embodiment, the current train may be a train traveling on a heavy-haul railway capable of inter-train communication. It should be understood that a heavy-haul railway refers to a railway with large gross vehicle weight, heavy-axle-load freight cars, or a high traffic density and volume, primarily used to transport large raw materials and cargo. Inter-train communication refers to a communication technology that enables direct information exchange between trains. Through inter-train communication, trains can obtain real-time operating information from adjacent trains, enabling more precise driving control and interval protection. Using inter-train communication technology, trains can detect the operating status and location of adjacent trains in real time, issuing timely collision warnings and avoiding collision accidents. In general, inter-train communication technology can be implemented via a 5G communication network. The inter-train data acquisition unit may be an execution module within the communication data processing system that is responsible for acquiring and processing reception-related data associated with communication reception records. The reception-related data associated with the communication reception record acquired by the vehicle-to-vehicle data acquisition unit may include vehicle-to-vehicle communication data transmitted by other trains currently traveling and in vehicle-to-vehicle communication with the current train. The communicating train may be a train capable of vehicle-to-vehicle communication with the current train via an ad hoc network. In other words, the communicating train may be a train capable of vehicle-to-vehicle communication with the current train. It is understood that an ad hoc network, also known as a mobile ad hoc network, is a multi-hop, temporary autonomous system consisting of a group of mobile nodes equipped with wireless transceivers and lacking fixed infrastructure. The basic principle of an ad hoc network is that nodes communicate with each other via wireless links, forming an arbitrary mesh topology. When a node wants to send data, it first determines a path to the destination node using a routing protocol, then obtains channel usage rights through a channel access mechanism and transmits the data. In other words, vehicle-to-vehicle communication can be performed between the current train and the communicating train via a wireless link. The first vehicle-to-vehicle communication data may be service data transmitted by the communicating train to the current train. The location information acquisition unit may be an execution module in a communication data processing system for acquiring train location information. The location information acquisition unit may support at least one Global Navigation Satellite System (GNSS). Optionally, the location information acquisition unit may support the Beidou system and the Global Positioning System (GPS). The received location information may represent the location of the current train when receiving the communication data. The received location information may include a variety of information that can represent the train's location, optionally including the train's latitude and longitude and / or the train's altitude. The received timestamp may be a time certificate representing the time when the current train receives the communication data, that is, representing the corresponding reception time when the current train receives the communication data.The reception timestamp is usually expressed in digital form, including date and time information. The reception time may be the time when the vehicle-to-vehicle data acquisition unit receives the first vehicle-to-vehicle communication data. The communication log receiving unit may be an execution module in the communication data processing system for collecting communication-related information. Signal-related information may be a parameter associated with the signal reception quality. Optionally, the signal-related information includes signal reception field strength and signal-to-noise ratio. The signal reception field strength reflects the intensity of the electromagnetic waves emitted by the radio station in space. The greater the signal reception field strength, the better the signal reception quality of the train. The signal-to-noise ratio refers to the ratio between the intensity of the received useful signal and the intensity of the received interference signal, and is an important indicator for measuring the quality of signal transmission. The higher the signal-to-noise ratio, the better the signal quality and the more accurate the ability to transmit and receive information.

[0037] It should be noted that to avoid signal conflicts and interference and ensure accurate data transmission and processing, each train can have a corresponding communication time window. Each train can send communication data to other trains within the communication time window corresponding to the train, so that only data from a specific train can be received and processed at any given time, thereby ensuring the orderliness and accuracy of the data. Based on this, at the same time, the number of communication trains sending communication data to the first train that the current train receives can be one.

[0038] In this embodiment, when the current train starts running, the communication data processing system set in the current train can be started. Furthermore, during the operation of the current train, when the first vehicle-to-vehicle communication data sent by the communication train is received through the vehicle-to-vehicle data acquisition unit, the location information corresponding to the current train at the receiving moment can be collected through the position information acquisition unit, and the collected location information can be used as the receiving location information. In addition, the time information corresponding to the receiving moment can be collected through the position information acquisition unit, and the collected time information can be used as the receiving timestamp. Furthermore, the collected receiving location information and receiving timestamp can be sent to the vehicle-to-vehicle data acquisition unit. Furthermore, when the first vehicle-to-vehicle communication data sent by the communication train is received through the vehicle-to-vehicle data acquisition unit, the signal receiving field strength and signal-to-noise ratio corresponding to the current train at the receiving moment can be collected through the communication log receiving unit, and the collected signal receiving field strength and signal-to-noise ratio can be used as signal correlation information. Furthermore, the collected signal correlation information can be sent to the vehicle-to-vehicle data acquisition unit.

[0039] S120. Determine a communication reception record based on the first vehicle communication data, the reception timestamp, the reception location information, and the signal association information through the vehicle-to-vehicle data acquisition unit, and associate the communication reception record with a pre-generated reception record identifier corresponding to the communication reception record and store it in the information storage unit.

[0040] Among them, the communication reception record refers to the communication data and information recorded by the receiving end during the communication process. The reception record identifier can be identification information used to identify or query the communication reception record. The reception record identifier can be information that uniquely identifies the communication reception record, that is, the reception record identifier can be a unique index of the corresponding communication reception record. Optionally, the reception record identifier can be a string consisting of at least one character, and the character type includes at least one of numbers, text and English. It should be noted that the reception record identifier can be generated based on the communication reception record, and each communication reception record corresponds to a unique reception record identifier. The information storage unit can be an execution module in the communication data processing system for storing the communication reception records and communication transmission records generated during the train travel.

[0041] In this embodiment, when the vehicle-to-vehicle data acquisition unit receives the first vehicle-to-vehicle communication data, the reception timestamp, the reception location information and the signal association information, the vehicle-to-vehicle data acquisition unit can determine the communication reception record based on the first vehicle-to-vehicle communication data, the reception timestamp, the reception location information and the signal association information.

[0042] Optionally, the communication reception record is determined based on the first vehicle-to-vehicle communication data, the receiving timestamp, the receiving location information and the signal association information, including: determining the second train identifier corresponding to the communication train that sends the first vehicle-to-vehicle communication data based on the receiving timestamp; and taking the first vehicle-to-vehicle communication data, the receiving timestamp, the receiving location information, the signal association information, the second train identifier and the first train identifier corresponding to the current train as the communication reception record.

[0043] The second train identifier may be information used to uniquely identify the communication train that sent the inter-train communication data. The first train identifier may be information used to uniquely identify the current train. Optionally, both the first train identifier and the second train identifier may be a train number or a custom train code.

[0044] In this embodiment, when the vehicle-to-vehicle data acquisition unit receives a receiving timestamp, the second train identifier corresponding to the communication train that sends the first vehicle-to-vehicle communication data can be determined according to the communication time window corresponding to the receiving timestamp.

[0045] Optionally, determining the second train identifier corresponding to the communication train that sends the first vehicle-to-vehicle communication data based on the receiving timestamp includes: obtaining preset communication time slot corresponding information, and comparing the receiving timestamp with the communication time slot corresponding information; wherein the communication time slot corresponding information includes at least one communication time window and a train identifier corresponding to each communication time window; when the communication time window where the receiving timestamp is located is determined from at least one communication time window, the train identifier corresponding to the determined communication time window is used as the second train identifier corresponding to the communication train that sends the first vehicle-to-vehicle communication data.

[0046] The communication time slot correspondence information can be used to characterize the correspondence between communication time windows and train identifiers. The communication time slot correspondence information can include at least one communication time window and the train identifier corresponding to each communication time window. It should be noted that to avoid signal conflicts and interference and ensure the orderly and accurate transmission and processing of data, a corresponding communication time window can be pre-set for each train, and the communication time slot correspondence information can be determined based on the train identifier and the communication time window corresponding to the train. Furthermore, upon receiving first-train communication data sent by a communication train, the second train identifier corresponding to the communication train that sent the first-train communication data can be determined based on the received timestamp. For example, assume that the train corresponding to the communication time window of 0 milliseconds to 250 milliseconds is Train A, and the train corresponding to the communication time window of 250 milliseconds to 500 milliseconds is Train B. Furthermore, if the received timestamp is received by the train-to-train data acquisition unit, and the number of milliseconds in the received timestamp is 150 milliseconds, then the communication train that sent the first-train communication data is Train B.

[0047] As an optional implementation of this embodiment, a vehicle-to-vehicle data acquisition unit may acquire preset communication time slot corresponding information, where the communication time slot corresponding information includes at least one communication time window and a train identifier corresponding to each communication time window. Furthermore, the received timestamp may be compared with the communication time slot corresponding information, i.e., the received timestamp may be compared with each communication time window. Furthermore, when the communication time window in which the received timestamp is located is determined from the at least one communication time window, the train identifier corresponding to the determined communication time window may be used as the second train identifier corresponding to the communication train that sent the first vehicle-to-vehicle communication data.

[0048] When the second train identifier corresponding to the communicating train is determined, the first train identifier corresponding to the current train can be determined. Furthermore, a communication reception record can be generated based on the first train-to-train communication data, the reception timestamp, the reception location information, the signal association information, the second train identifier, and the first train identifier. Furthermore, a reception record identifier can be generated based on the communication reception record, and the communication reception record and the reception record identifier can be associated and stored in an information storage unit.

[0049] S130. When the second vehicle communication data to be sent to the communication train is obtained through the communication log sending unit, the sending position information and sending timestamp corresponding to the current train at the sending moment are collected through the position information acquisition unit, and the sending position information and sending timestamp are sent to the communication log sending unit.

[0050] The communication log sending unit may be an execution module in a communication data processing system for processing communication data. The second-vehicle communication data may be service data sent by the current train to the communicating train. It should be noted that the communication train that sent the first-vehicle communication data received by the current train and the communication train to which the current train is about to send the second-vehicle communication data may be the same train or different trains. It should also be noted that the number of communication trains to which the current train is about to send the second-vehicle communication data may be one or more. The sending location information may represent the location of the current train when the communication data is sent. The sending location information may include various information that can represent the train's location, optionally including the train's latitude and longitude and / or the train's altitude. The sending timestamp may be a time certificate representing the time when the current train sent the communication data, i.e., the time corresponding to the sending of the communication data by the current train. The sending timestamp is typically expressed in digital form, including date and time information. The sending time may be the time when the current train sends the second-vehicle communication data to the communicating train.

[0051] In this embodiment, during the current train's travel, if there is second-train communication data to be sent to the communicating train, in order to record the occurrence of the communication data, the second-train communication data can be obtained by the communication log sending unit. Furthermore, if the second-train communication data to be sent to the communicating train is obtained by the communication log sending unit, the position information acquisition unit can collect the position information corresponding to the current train at the time of sending and use the collected position information as the sending position information. Furthermore, the position information acquisition unit can collect the time information corresponding to the current train at the time of sending and use the collected time information as the sending timestamp. Furthermore, the collected sending position information and sending timestamp can be sent to the communication log sending unit.

[0052] S140. Determine a communication sending record according to the second vehicle communication data, the sending timestamp, and the sending location information through the communication log sending unit, and associate the communication sending record with a pre-generated sending record identifier corresponding to the communication sending record and store it in the information storage unit.

[0053] A communication transmission record refers to the communication data and information recorded by the transmitting end during the communication process. A transmission record identifier can be identification information used to identify or query a communication transmission record. The transmission record identifier can be information that uniquely identifies a communication transmission record, i.e., the transmission record identifier can be a unique index for the corresponding communication transmission record. Optionally, the transmission record identifier can be a string consisting of at least one character, where the character type includes at least one of numbers, text, and English. It should be noted that the transmission record identifier can be generated based on the communication transmission record, and each communication transmission record corresponds to a unique transmission record identifier.

[0054] In this embodiment, when the communication log sending unit receives the sending location information and sending timestamp sent by the location information acquiring unit, the communication sending record can be determined according to the received second vehicle communication data, sending location information and sending timestamp.

[0055] It should be noted that in order to be able to determine the communication sending end and communication receiving end corresponding to the communication sending record based on the communication sending record when analyzing the communication data later, the train identification of the current train and the communication train to be sent to can also be added when determining the communication sending record.

[0056] Optionally, the communication sending record is determined based on the second vehicle-to-vehicle communication data, sending timestamp, and sending location information, including: determining the first train identifier corresponding to the current train and the third train identifier corresponding to the communicating train; determining the communication sending record based on the second vehicle-to-vehicle communication data, sending timestamp, sending location information, the first train identifier, and the third train identifier.

[0057] The third train identifier may be information for uniquely identifying the communication train to which the message is to be sent. Alternatively, the third train identifier may be a train number or a custom train code.

[0058] As an optional implementation of this embodiment, a first train identifier corresponding to the current train and a third train identifier corresponding to the communicating train can be determined. Furthermore, a communication transmission record can be generated based on the second train-to-train communication data, the transmission timestamp, the transmission location information, the third train identifier, and the first train identifier. Furthermore, a transmission record identifier can be generated based on the communication transmission record, and the communication transmission record and the transmission record identifier can be associated and stored in an information storage unit.

[0059] In this embodiment, while the current train is traveling, at least one determined communication reception record and its corresponding reception record identifier can be stored in an information storage unit within a communication data processing system within the current train; and at least one determined communication transmission record and its corresponding transmission record identifier can be stored in the information storage unit. Furthermore, when both the current train and a communicating train with which the current train has a train-to-train communication relationship have completed their journeys, the stored communication reception record, reception record identifier, communication transmission record, and transmission record identifier can be retrieved from the information storage units of the current train and the communicating train. Furthermore, the retrieved communication reception record, reception record identifier, communication transmission record, and transmission record identifier can be analyzed to perform a communication failure analysis on the communication status between the current train and the communicating train based on the communication reception record, reception record identifier, communication transmission record, and transmission record identifier.

[0060] For example, Figure 2 FIG. 1 is a structural diagram of a communication data processing system provided according to an embodiment of the present invention. Figure 2 As shown, the communication data processing system includes: a system initialization unit, a vehicle data acquisition unit, a position information acquisition unit, a communication log sending unit, a communication log receiving unit, and an information storage unit.

[0063] Figure 3This is a flowchart of a method for processing inter-train communication data provided by the second embodiment of the present invention. On the basis of the above embodiment, when the current train has completed its journey, a communication fault analysis can also be performed based on the information stored in the information storage unit. Optionally, when the current train and at least one communication train that has a train-to-train communication relationship with the current train have completed their journeys, a communication fault analysis is performed based on the communication-related information stored in the information storage units of the current train and the communication train, so as to process the train with the communication fault according to the fault analysis results; wherein the communication-related information includes at least one communication reception record, a communication reception identifier corresponding to each communication reception record, at least one communication transmission record, and a communication transmission identifier corresponding to each communication transmission record. Its specific implementation method can be found in the technical solution of this embodiment. Among them, technical terms that are the same or similar to those in the above embodiment are not repeated here.

[0064] like Figure 3 As shown, the method includes:

[0065] S210. During the travel of the current train, when the first inter-vehicle communication data sent by the communication train is received through the inter-vehicle data acquisition unit, the receiving position information and receiving timestamp corresponding to the current train at the receiving moment are collected through the position information acquisition unit, and the receiving position information and receiving timestamp are sent to the inter-vehicle data acquisition unit, and the signal association information corresponding to the current train at the receiving moment is collected through the communication log receiving unit, and the collected signal association information is sent to the inter-vehicle data acquisition unit.

[0066] S220. Determine a communication reception record based on the first vehicle-to-vehicle communication data, the reception timestamp, the reception location information, and the signal association information through the vehicle-to-vehicle data acquisition unit, and associate the communication reception record with a pre-generated reception record identifier corresponding to the communication reception record and store it in the information storage unit.

[0067] S230. When the second vehicle communication data to be sent to the communication train is obtained through the communication log sending unit, the sending position information and sending timestamp corresponding to the current train at the sending moment are collected through the position information acquisition unit, and the sending position information and sending timestamp are sent to the communication log sending unit.

[0068] S240. Determine a communication sending record according to the second vehicle-to-vehicle communication data, the sending timestamp, and the sending location information through the communication log sending unit, and associate the communication sending record with a pre-generated sending record identifier corresponding to the communication sending record and store it in the information storage unit.

[0069] S250. When the current train and at least one communicating train that has a train-to-train communication relationship with the current train have completed their journeys, a communication fault analysis is performed based on the train-to-train communication information stored in the information storage units of the current train and the communicating train, so as to process the train with the communication fault based on the fault analysis results; wherein the train-to-train communication information includes at least one communication reception record, a communication reception identifier corresponding to each communication reception record, at least one communication transmission record, and a communication transmission identifier corresponding to each communication transmission record.

[0070] The vehicle-to-vehicle communication information can be understood as information stored in the information storage unit that represents the vehicle-to-vehicle communication status during the train's journey. For the current train and at least one communicating train, the vehicle-to-vehicle communication information stored in the train's information storage unit may include at least one communication reception record, a communication reception identifier corresponding to each communication reception record, and at least one communication transmission record, and a communication transmission identifier corresponding to each communication transmission record.

[0071] In this embodiment, when the current train and at least one communicating train in a train-to-train communication relationship with the current train have both completed their journeys, the train-to-train communication information stored in the current train's information storage unit and the train-to-train communication information stored in the information storage units of each communicating train can be retrieved. Furthermore, based on the retrieved multiple train-to-train communication information, a communication failure analysis can be performed on the communication process between the current train and each communicating train. Furthermore, if the communication failure analysis results indicate a train with a communication failure, timely action can be taken on that train.

[0072] In this embodiment, communication fault analysis based on vehicle-to-vehicle communication information may include at least two fault analysis methods, optionally including generating a driving communication video based on the vehicle-to-vehicle communication information to perform communication fault analysis based on the driving communication video, and / or traversing and comparing the vehicle-to-vehicle communication information to perform communication fault analysis based on the comparison results, etc.

[0073] Optionally, a communication fault analysis is performed based on the vehicle-to-vehicle communication information stored in the information storage units of the current train and the communicating train, including: obtaining the vehicle-to-vehicle communication information stored in the information storage unit of the current train and the vehicle-to-vehicle communication information stored in the information storage units of each communicating train, and obtaining the travel map information corresponding to the current train; generating a travel communication video corresponding to the current train based on at least one communication reception record and at least one communication transmission record among the multiple acquired vehicle-to-vehicle communication information and the travel map information, and displaying the travel communication video, so as to perform a communication fault analysis based on the dynamic display information of the travel communication video.

[0074] Among them, the itinerary map information can be understood as an electronic map associated with the itinerary of the train. The itinerary map information may include the waypoints passed by the train during its journey. The itinerary communication video can be understood as a video that can characterize the train's travel conditions and the train-to-train communication conditions during the train's travel. The itinerary communication video is at least used to indicate the train-to-train communication conditions of the current train and the various communication trains associated with it during the travel process, as well as the train travel conditions of the current train and the various communication trains. Optionally, the itinerary communication video may include the travel process of the current train and the various communication trains, the change process of the receiving field strength of the current train and the various communication trains, and / or the change process of the effective communication coverage range of the current train and the various communication trains. The dynamic display information may be the dynamic change effect of the itinerary communication video displayed in the interface, that is, the dynamic change effect of the video content included in the itinerary communication video.

[0075] As an optional implementation of this embodiment, when the current train and at least one communicating train in a train-to-train communication relationship with the current train have both completed their journeys, the train-to-train communication information stored in the current train's information storage unit and the train-to-train communication information stored in the information storage units of each communicating train can be retrieved, and the journey map information corresponding to the current train can be obtained. Furthermore, a journey communication video corresponding to the current train can be generated based on at least one communication reception record and at least one communication transmission record from the multiple acquired train-to-train communication information, as well as the journey map information. The generated journey communication video can then be displayed, and communication fault analysis can be performed based on the dynamic display information of the journey communication video. This configuration provides an intuitive, real-time, dynamic view of the train-to-train communication status of different trains, at different train distances, and at different geographic locations. Furthermore, the dynamic display of the train formation's movement, communication coverage, and packet loss and error status can be dynamically displayed. Combined with the map background, the impact of the geographical environment and road direction on the ad hoc network's train-to-train communication can be intuitively understood, and communication status along the route can be more intuitively displayed, recorded, and analyzed.

[0076] For example, assume a heavy-load ad hoc network train consists of Train 01, Train 02, and Train 03. Train 02 is the current train, and Train 01 and Train 03 are communicating trains with the current train in a vehicle-to-vehicle communication relationship. In the journey communication video, trains can be represented by arrows of different colors. For example, a blue arrow represents Train 01, a yellow arrow represents Train 02, and a green arrow represents Train 03. The train arrows can be moved in real time based on the acquired receive position information, transmit position information, receive timestamp, and transmit timestamp. Different circles represent the effective coverage range of different train signals: a blue circle represents the vehicle-to-vehicle communication coverage range of Train 01, a green circle represents the vehicle-to-vehicle communication coverage range of Train 03, and a yellow circle represents the vehicle-to-vehicle communication coverage range of Train 02. The radius of the effective coverage circle is an estimate, with a minimum of 1 km plus the radius of the train itself and a maximum of the actual radius received by the remaining trains. For example, if data sent by Train 01 is received by Train 03, the blue circle for Train 01 can be expanded to include Train 03. The color density of the effective coverage area is determined by the strength of the signal reception field detected by the receiver. The darker the color (e.g., yellow, green, blue), the higher the signal strength. Under ideal communication coverage conditions, Trains 01, 02, and 03 appear on the journey communication video as a series of moving arrows and a series of intersecting circles. The entire graphic moves on the map over time. Under suboptimal vehicle-to-vehicle communication conditions, Trains 01, 02, and 03 appear on the journey communication video as a series of moving arrows and a series of independent circles. The lack of intersection between the covered circles indicates that the effective coverage of the preceding and following trains has not reached the previous / next train, and the entire graphic will also move on the map over time.

[0077] Optionally, a communication fault analysis is performed based on the vehicle-to-vehicle communication information stored in the information storage units of the current train and the communication train, including: obtaining the vehicle-to-vehicle communication information stored in the information storage unit of the current train and the vehicle-to-vehicle communication information stored in the information storage units of each communication train; for at least one communication sending identifier included in the vehicle-to-vehicle communication information corresponding to the current train, obtaining a corresponding communication sending record based on the communication sending identifier, and obtaining a third train identifier of the communication train corresponding to the communication sending identifier from the communication sending record, and obtaining a sending timestamp included in the communication sending record; determining a target communication train corresponding to the third train identifier from each communication train, and performing a communication fault analysis on the communication between the current train and the target communication train based on the vehicle-to-vehicle communication information and the sending timestamp corresponding to the target communication train.

[0078] As an optional implementation of this embodiment, when the current train and at least one communicating train in a train-to-train communication relationship with the current train have both completed their journeys, the train-to-train communication information stored in the current train's information storage unit and the train-to-train communication information stored in the information storage units of each communicating train can be obtained. Furthermore, based on at least one communication transmission identifier included in the train-to-train communication information corresponding to the current train, a communication transmission record corresponding to the communication transmission identifier can be obtained from the train-to-train communication information corresponding to the current train. The third train identifier of the communication train to which the communication transmission record is to be transmitted can be obtained from the communication transmission record, and the transmission timestamp included in the communication transmission record can be obtained. Furthermore, based on the obtained third train identifier, the communication train corresponding to the third train identifier can be determined from each communicating train and used as the target communication train. Furthermore, based on the train-to-train communication information and transmission timestamp corresponding to the target communication train, communication failure analysis can be performed on the communication between the current train and the target communication train.

[0079] Optionally, a communication fault analysis is performed on the communication between the current train and the target communication train based on the vehicle-to-vehicle communication information corresponding to the target communication train, the sending timestamp and the first train identifier of the current train, including: screening at least one communication reception record included in the vehicle-to-vehicle communication information corresponding to the target communication train based on the sending timestamp and the first train identifier; when a target reception record matching the sending timestamp and the first train identifier is determined from at least one communication reception record, performing data comparison on the target reception record and the communication transmission record corresponding to the sending timestamp to determine a fault analysis result based on the data comparison result, wherein the data comparison result includes data consistency or data inconsistency and some communication data is missing from the first vehicle-to-vehicle communication data in the communication reception record; the fault analysis result includes no fault or the presence of a communication fault; or, when a target reception record matching the sending timestamp and the first train identifier is not determined from at least one communication reception record, determining that there is a communication fault between the current train and the target communication train.

[0080] The target reception record may be a communication reception record in which the time difference between the reception timestamp and the transmission timestamp included therein is a preset difference value and includes a first train identification.

[0081] As an optional implementation of this embodiment, when the sending timestamp and the first train identifier are determined, at least one communication reception record included in the vehicle-to-vehicle communication information corresponding to the target communication train can be screened based on the sending timestamp and the first train identifier. Furthermore, when it is determined from at least one communication reception record that the time difference between the receiving timestamp and the sending timestamp included therein is a preset difference value, and the communication reception record including the first train identifier is included, the determined communication reception record can be used as the target reception record. Afterwards, data comparison can be performed between the target reception record and the communication transmission record corresponding to the sending timestamp. Furthermore, when the first vehicle-to-vehicle communication data included in the target reception record is consistent with the second vehicle-to-vehicle communication data in the communication transmission record, the data comparison result can be determined to be data consistency, and the fault analysis result can be determined to be fault-free. In a case where the first vehicle-to-vehicle communication data included in the target reception record is inconsistent with the second vehicle-to-vehicle communication data in the communication transmission record and some communication data is missing from the first vehicle-to-vehicle communication data in the target reception record, it can be determined that the data comparison result is data inconsistency and some communication data is missing from the first vehicle-to-vehicle communication data in the target reception record, and the fault analysis result is determined to be a packet loss communication fault.

[0082] If no target reception record matching the transmission timestamp and the first train identifier is determined from at least one of the communication reception records, it may be determined that a communication failure exists between the current train and the target communication train. The communication failure may include a failure in train communication reception performance and / or a communication coverage failure.

[0083] The technical solution of the embodiment of the present invention is to perform communication fault analysis based on the vehicle-to-vehicle communication information stored in the information storage units of the current train and the communication train when the current train and at least one communication train that has a vehicle-to-vehicle communication relationship with the current train have completed their journeys, so as to process the train with the communication fault according to the fault analysis result, thereby achieving the effect of performing communication fault analysis on the inter-train communication situation based on the stored vehicle-to-vehicle communication information, thereby improving the efficiency and accuracy of the inter-train communication fault analysis and enhancing the overall quality of the vehicle-to-vehicle communication in the ad hoc network.
