[0033] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0034] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0035] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0036] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0037] In the technical solution of the present disclosure, the user information (including but not limited to user personal information, user image information, user device information, such as location information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved are all information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with relevant laws, regulations and standards, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0038] In the process of implementing the present disclosure, it was found that the train uses a redundant communication network for data transmission. The redundant communication network may include a first network and a second network. During the operation of the train, the data transmitted by the first network is used first to control the train. If the communication network port of a single subsystem of the first network fails or the data is invalid, the data sent by the second network is used. However, there is currently a lack of corresponding detection means to judge the consistency of the data sent by the subsystem to the first network and the second network. If the subsystem has inconsistent data in the first network and the second network due to its own or external line reasons, it is impossible to promptly remind the driver and maintenance personnel, and the vehicle is at risk of operating with a problem.

[0039] In view of this, an embodiment of the present disclosure provides a train fault determination method, comprising: in response to a received train fault judgment request, obtaining a first data packet and a second data packet, wherein the first data packet represents a data packet output by a train controller and transmitted via a first network, and the second data packet represents a data packet output by a train controller and transmitted via a second network, and the transmission functions of the first network and the second network are the same; determining the type of network port used to output the first data packet and the second data packet according to the number of controllers; and obtaining the train fault information by comparing the contents of the first data packet and the second data packet according to the type of network port.

[0040] Figure 1 The application scenario diagram of the train fault determination method according to an embodiment of the present disclosure is schematically shown.

[0041] like Figure 1 As shown, the application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0042] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0043] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0044] The server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0045] It should be noted that the train fault determination method provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the train fault determination device provided in the embodiment of the present disclosure can generally be set in the server 105. The train fault determination method provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the train fault determination device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105.

[0046] It should be understood that Figure 1 The number of the first terminal device, the second terminal device, the third terminal device, the network and the server in the embodiment is only for illustration. According to the implementation requirements, there may be any number of terminal devices, networks and servers.

[0047] Figure 2 A flow chart of a train fault determination method according to an embodiment of the present disclosure is schematically shown.

[0048] like Figure 2 As shown, the train fault determination method 200 of this embodiment includes operations S210 to S230.

[0049] In operation S210, in response to a received train fault determination request, a first data packet and a second data packet are acquired.

[0050] In operation S220 , a network port type for outputting the first data packet and the second data packet is determined according to the number of controllers.

[0051] In operation S230, according to the network port type, the fault information of the train is obtained by comparing the contents of the first data packet and the second data packet.

[0052] According to the embodiments of the present disclosure, the Train Control and Monitoring System (TCMS) integrates the control, monitoring, diagnosis and communication functions of the train, connects various devices distributed throughout the train to form a train communication network through a control bus, and realizes centralized monitoring of various subsystems of the train and the entire vehicle. The topology of the train communication network can include multiple types. For example, a composite topology of a completely physically isolated dual ring topology and a star topology can be adopted, and the communication bus of the composite topology of a completely physically isolated dual ring topology and a star topology can adopt an Ethernet bus.

[0053] In one embodiment, the communication network of the train may include a first network and a second network. The first network and the second network have the same transmission function, and redundancy of the network structure of the train can be achieved. The first network is mainly used to transmit control signals for controlling the train, and the second network is used to transmit control signals for the train. The control signals transmitted in the second network should theoretically be the same as the control signals transmitted in the first network. In addition, the second network can also be used to transmit intelligent operation and maintenance data of the train. The redundant communication network can use another network and the data packets transmitted in another network for communication when one of the networks or the data packets transmitted in one of the networks are abnormal, thereby improving the reliability and stability of the communication network of the train and reducing the cost and risk of maintenance.

[0054] According to an embodiment of the present disclosure, the first data packet may represent a data packet output by the controller of the train and transmitted via the first network, and the second data packet may represent a data packet output by the controller of the train and transmitted via the second network.

[0055] In one embodiment, the train control and monitoring system may include multiple subsystems, for example, a traction subsystem, a braking subsystem, a pyrotechnic subsystem, a running gear subsystem, a door subsystem, an air conditioning subsystem, and other key subsystems. The key subsystem may adopt a dual-home design, and two network ports may be connected to the first network and the second network respectively.

[0056] In one embodiment, for the pyrotechnics subsystem, the running gear subsystem or the passenger information subsystem, each controller located in the head car can output the data packet of the entire train, wherein the first car and the last car of a train are both the head cars of the train. For example, a train may include 10 cars, then the first car and the tenth car are both the head cars. The controllers of the two head cars use a single network port to access the first network and the second network respectively. The pyrotechnics subsystem, the running gear subsystem or the passenger information subsystem can use a single network port to access the data packet of the entire train output by the controller located in the head car to the first network and the second network respectively. For the door subsystem, each car can be configured with 2 controllers, which can transmit the status data of all the doors of this car. The 2 controllers of each car use a single network port to intervene in the first network and the second network respectively, to ensure the redundancy and reliability of the entire train communication network. For the traction brake subsystem or the air conditioning subsystem, each car can be configured with 1 controller, and the controller of each car uses a dual network port to access the first network and the second network respectively.

[0057] In one embodiment, the controller is used to output the first data packet and the second data packet. The network port type of the controller used to output the first data packet and the second data packet can be determined according to the number of controllers. For example, when the number of controllers that output the first data packet and the second data packet is 2, the network port type of the first data packet and the second data packet can be the first type. For another example, when the number of controllers that output the first data packet and the second data packet is 10, the network port type of the first data packet and the second data packet can be the second type.

[0058] According to an embodiment of the present disclosure, the content of the first data packet may represent the data carried by the first data packet, and the content of the second data packet may represent the data carried by the second data packet. In one embodiment, different network port types may correspond to different data packet comparison rules, and therefore, the data packet comparison rule corresponding to the network port type may be determined according to the network port type, so that the contents of the first data packet and the second data packet may be compared according to the data packet comparison rule, and then the fault information of the train may be obtained.

[0059] According to an embodiment of the present disclosure, the network port type can be determined according to the number of controllers that output the first data packet and the controllers that output the second data packet, and then according to the network port type, the contents of the first data packet and the second data packet are compared to obtain the fault information of the train. Since the first network and the second network are redundant, the contents of the first data packet transmitted in the first network and the second data packet transmitted in the second network should be the same. If the contents of the first data packet and the second data packet are different, it can be considered that the data transmitted in the redundant communication network of the train is abnormal, and then it can be considered that the train may have a fault. By providing fault warning for trains in which the first data packet transmitted by the first network and the second data packet transmitted by the second network are inconsistent, the intelligence level of the train and the train operation safety are improved.

[0060] According to an embodiment of the present disclosure, according to the network port type, the fault information of the train is obtained by comparing the contents of the first data packet and the second data packet, including: according to the network port type, determining the data packet comparison rule corresponding to the network port type; according to the data packet comparison rule, obtaining the fault information of the train by comparing the contents of the first data packet and the second data packet.

[0061] In one embodiment, the network port type may include multiple types, and each network port type may correspond to a data packet comparison rule. For example, the network port type may be a single network port type, and the data packet comparison rule may include a comparison rule corresponding to the single network port type. For another example, the network port type may also be a dual network port type, and the data packet comparison rule may include a comparison rule corresponding to the dual network port type. Thus, the data packet comparison rule corresponding to the network port type may be determined according to the network port type.

[0062] In one embodiment, when the data packet comparison rule is determined, the fault information of the train can be obtained by comparing the contents of the first data packet and the second data packet.

[0063] Figure 3A The structure of a data packet output by a dual-network-port type controller according to an embodiment of the present disclosure is schematically shown. Figure 3B The structure of a data packet output by a controller of a single network port type according to an embodiment of the present disclosure is schematically shown.

[0064] According to an embodiment of the present disclosure, the identification information may be a signal indicating whether the data packet is reliable and working properly. The content information may be a signal indicating the data content carried by the data packet. Figure 3A As shown, the content of the data packet output by the dual-network port type controller may include identification information 310 and content information 320. The length of the identification information 310 may be 4 bytes, for example, the identification information 310 may be represented by 4 bytes X1, X2, X3, and X4. The length of the content information 320 is not limited, for example, multiple bytes X5, X6, ..., X7 may be used. n Indicates content information 320.

[0065] According to an embodiment of the present disclosure, the valid bit information represents the portion of the data packet output by the controller that carries useful information, and the device status information represents the data of the device status. Figure 3B As shown in FIG. 1 , the content of the data packet output by the controller of the single network port type may include valid bit information 330 and device status data 340. The length of the valid bit information 330 may be 1 byte, for example, one byte Y1 may be used to represent the valid bit information 310. The length of the device status data 340 is not limited, for example, multiple bytes Y5, ..., Y m Device status data 340 is indicated.

[0066] According to an embodiment of the present disclosure, when the network port type is determined, the corresponding data packet comparison rule can be determined, and then based on the data packet comparison rule, the contents of the first data packet and the second data packet are compared. When the contents of the first data packet and the second data packet are inconsistent, the fault information of the train can be obtained. Since the fault information is obtained when the network port type is determined, different network port types can correspond to different fault information, thereby improving the accuracy of the fault information and further improving the operation safety of the train.

[0067] According to an embodiment of the present disclosure, according to a data packet comparison rule, by comparing the contents of a first data packet and a second data packet, the fault information of the train is obtained, including: caching a first target number of first data packets and second data packets; determining a first target data packet and a second target data packet according to first identification information and second identification information; determining the number of inconsistent data packets according to first content information of the first target data packet and second content information of the second target data packet; and obtaining the fault information of the train when the number of inconsistent data packets is greater than the second target number.

[0068] According to an embodiment of the present disclosure, the first identification information and the second identification information can be signals representing whether the data packet is reliable and working normally. In one embodiment, the first identification information and the second identification information can have 4 bytes, and when the first target number of first identification information and second identification information of the cache are changed in sequence, it can be represented that the redundant communication network ports of the train are communicating normally. When the redundant communication network ports are communicating normally, the first data packet and the second data packet can be compared, otherwise, the first data packet and the second data packet are not compared.

[0069] In one embodiment, the data packet comparison rule may include a first comparison rule corresponding to the dual network port type. The first content information and the second content information may represent the data content carried by the data packet. The content of the first data packet may include first identification information and first content information, and the content of the second data packet may include second identification information and second content information.

[0070] In one embodiment, the first target number can be set according to demand or experience. For example, the first target number can be set to 20. The first comparison rule can represent a data packet comparison rule corresponding to the dual network port type. For the first comparison rule, the first data packet and the second data packet to be compared are first cached. The number of the cached first data packet and the second data packet is the same, which can be the first target number.

[0071] According to an embodiment of the present disclosure, the first target data packet may represent a data packet having the same first identification information and second identification information in the first data packet, and the second target data packet may represent a data packet having the same first identification information and second identification information in the second data packet. In one embodiment, the first target data packet and the second target data packet having the same first identification information and second identification information may be determined based on the first identification information and the second identification information.

[0072] In one embodiment, for the first comparison rule, any first identification information can also be compared with the second identification information of the first target quantity. When any first identification information is different from the second identification information of the first target quantity, a data packet inconsistency can be recorded.

[0073] In one embodiment, when the first identification information and the second identification information are the same, the number of inconsistent data packets can be determined by comparing the content information of the first data packet and the second data packet, that is, in the order of the data packets, by comparing the first content information of the first target data packet and the second content information of the second data packet, when the first content information and the second content information are inconsistent, a data packet inconsistency is recorded, and the number of inconsistent data packets in the first target number is counted to determine the number of inconsistent data packets.

[0074] In one embodiment, the second target number can be determined based on the first target number. For example, when the first target number is 20, the second target number can be set to half of the first target number, that is, the second target number can be 10. When the number of inconsistent data packets is greater than the second target number, the fault information of the train can be obtained. For example, when the number of inconsistent data packets is 12 and the first target number is 20, the fault information of the train can be obtained.

[0075] According to an embodiment of the present disclosure, by using a first comparison rule to perform a content comparison on a first target number of first data packets and a second data packet of a cache, the number of inconsistent data packets can be determined. When the number of inconsistent data packets is greater than the second target number, fault information of the train can be obtained. By setting the first target number and the second target number, and considering the situation where the number of inconsistent data packets is greater than the second target number as the obtained train fault information, the accuracy of the obtained dual network port type fault information is improved, thereby improving the efficiency of fault determination.

[0076] Figure 4 The diagram schematically shows a schematic diagram of comparing the contents of a first data packet and a second data packet based on a second comparison rule according to an embodiment of the present disclosure.

[0077] like Figure 4As shown, when the first target number is 20, the content comparison process of the first data packet and the second data packet is performed, and the first identification information and the second identification information of the 20 data packets are compared in turn. When the first identification information and the second identification information of the 20 first data packets are the same, the first content information and the second content information of the 20 data packets are compared in turn, that is, the first identification information 41011 of the first first data packet 4101 and the second identification information 42011 of the second data packet 4201 are compared in turn, the first identification information 41021 of the second first data packet 4102 and the second identification information 42021 of the second second data packet 4202 are compared, and the first identification information 41201 of the 20th first data packet 4120 and the second identification information 42201 of the 20th second data packet 4220 are compared. When the first identification information of the ith data packet and the second identification information of the ith data packet are different, the data packet inconsistency is recorded once. For example, when the first identification information 41021 of the second first data packet 4102 and the second identification information 42021 of the second second data packet 4202 are different, a data packet inconsistency is recorded. When the first identification information and the second identification information of 20 data packets are the same, the first content information and the second content information of the 20 data packets are compared in sequence, that is, the first content information 41012 of the first first data packet 4101 and the second content information 42012 of the second data packet 4201 are compared in sequence, the first content information 41022 of the second first data packet 4102 and the second content information 42022 of the second second data packet 4202 are compared, and the first content information 41202 of the 20th first data packet 4120 and the second content information 42202 of the 20th second data packet 4220 are compared. When the first content information of the jth data packet and the second content information of the jth data packet are different, a data packet inconsistency is recorded. For example, when the first identification information and the second identification information of 20 data packets are the same, and the first content information 41022 of the second first data packet 4102 is different from the second content information 42022 of the second second data packet 4202, a data packet inconsistency is recorded. After the first target number of first data packets and second data packets are compared, the number of data packet inconsistencies is counted to obtain the number of data packet inconsistencies.

[0078] Figure 5 A flow chart of a train fault determination method according to yet another embodiment of the present disclosure is schematically shown.

[0079] like Figure 5 As shown, the train fault determination method of this embodiment includes operations S501 to S508.

[0080] In operation S501, when it is determined that the controller outputting the first data packet and the second data packet is of a dual-network port type, the data packet comparison rule is determined to be a first comparison rule.

[0081] In operation S502 , a first target number of first data packets and second data packets are buffered.

[0082] In operation S503, it is determined whether the network port has communication abnormality. If so, operation S508 is executed; if not, operation S504 is executed.

[0083] In operation S504, a first target data packet and a second target data packet are determined by comparing the first identification information and the second identification information.

[0084] In operation S505, when the first content information of the first target data packet is different from the second content information of the second target data packet or the first identification information of any first data packet is different from the second identification information of the first target data packet, a data packet inconsistency is recorded and the number of inconsistent data packets is counted.

[0085] In operation S506, it is determined whether the number of inconsistent data packets is greater than the second target number. If yes, operation S507 is performed; if no, operation S508 is performed.

[0086] In operation S507, dual network port type fault information is obtained.

[0087] In operation S508 , the dual-network-port type subsystem has no faults.

[0088] According to an embodiment of the present disclosure, according to the data packet comparison rules, the fault information of the train is obtained by comparing the contents of the first data packet and the second data packet, including: determining the third target data packet and the fourth target data packet according to the first valid bit information and the second valid bit information; determining the device status difference information by comparing the first device status data of the third target data packet and the second device status data of the fourth target data packet; and obtaining the fault information of the train according to the device status difference information and the predetermined train communication cycle.

[0089] In one embodiment, the data packet comparison rule may include a second comparison rule corresponding to a single network port type. The content of the first data packet may include first device status data and first valid bit information, and the content of the second data packet may include second device status data and second valid bit information.

[0090] According to an embodiment of the present disclosure, the first valid bit information and the second valid bit information can respectively represent the part of the first data packet carrying useful information and the part of the second data packet carrying useful information. The first valid bit information and the second valid bit information can be in two situations: valid or not. For example, when the first valid bit information and the second valid bit information are both 1, it can be represented that the content of the first data packet and the content of the second data packet are both valid. When the first valid bit information and the second valid bit information are both 0, it can be represented that the content of the first data packet and the content of the second data packet are both invalid.

[0091] In one embodiment, the comparison of the contents of the first data packet and the second data packet is performed only when all the first valid bit information and the second data valid bit information represent that the contents of the first data packet and the second data packet are valid; otherwise, the comparison of the contents of the first data packet and the second data packet is not performed.

[0092] According to an embodiment of the present disclosure, the third target data packet may represent a data packet in which the first valid bit information in the first data packet is valid, and the fourth target data packet may represent a data packet in which the second valid bit information in the second data packet is valid. Therefore, in one embodiment, the third target data packet and the fourth target data packet may be determined by the first valid bit information and the second valid bit information.

[0093] According to an embodiment of the present disclosure, the first device status data and the second device status data may characterize the status of the corresponding device. For example, the status of the device may include normal operation of the device. For another example, the status of the device may include abnormal operation of the device. By comparing the first device status data of the third target data packet with the second device status data of the fourth target data packet, the device status difference information may be determined, and the device status difference information may be the number of data packet inconsistencies or the duration of data inconsistency.

[0094] In one embodiment, the predetermined train communication cycle may represent the periodic interval of data packet transmission in the train communication network. The predetermined train communication cycle may be determined before the train runs. The train fault information may be obtained based on the device status difference information and the predetermined train communication cycle.

[0095] According to an embodiment of the present disclosure, when the first valid bit information and the second valid bit information represent that the contents of the first data packet and the second data packet are valid, the first device status data of the third target data packet and the second device status data of the fourth target data packet can be compared to determine the device status difference information. The device status difference information can be combined with the predetermined train communication cycle to obtain the train fault information. The combination of the device status difference information and the predetermined train communication cycle can make different train fault information correspond to different device status difference information, thereby improving the accuracy of the obtained train fault information for a single network port type, thereby improving the efficiency of fault determination.

[0096] According to an embodiment of the present disclosure, fault information of the train is obtained based on the equipment status difference information and the scheduled train communication cycle, including: when it is determined that the scheduled train communication cycle is the first communication cycle, and the equipment status difference information indicates that the duration of the inconsistency between the first equipment status data and the second equipment status data is greater than the first time threshold, the first fault information of the train is obtained; or, when it is determined that the scheduled train communication cycle is the second communication cycle, and the equipment status difference information indicates that the number of inconsistent data packets is greater than the first number threshold, the second fault information of the train is obtained.

[0097] In one embodiment, the predetermined train communication cycle may include a first communication cycle and a second communication cycle. For example, the first communication cycle may be 200 ms, and the second communication cycle may be 500 ms.

[0098] In one embodiment, the first time threshold may be determined based on the first communication cycle. For example, when the first communication cycle is 200 ms, the first time threshold may be set to 3 ms. When the predetermined train communication cycle is determined to be the first communication cycle, and the duration of the inconsistency between the first device status data and the second device status data represented by the device status difference information is greater than the first time threshold, the first fault information of the train is obtained.

[0099] In one embodiment, the first quantity threshold may be determined according to the second communication cycle. For example, when the second communication cycle is 500 ms, the first quantity threshold may be set to 10. When it is determined that the predetermined train communication cycle is the second communication cycle, and the number of inconsistent data packets represented by the device status difference information is greater than the first quantity threshold, the second fault information of the train may be obtained.

[0100] According to an embodiment of the present disclosure, a predetermined train communication cycle may include a first communication cycle and a second communication cycle. In different communication cycles, different threshold data may be set to obtain train fault information, thereby improving the flexibility of obtaining fault information and the accuracy of fault information.

[0101] Figure 6 The diagram schematically shows a schematic diagram of comparing the contents of a first data packet and a second data packet based on a first comparison rule according to an embodiment of the present disclosure.

[0102] like Figure 6 As shown, it is a process of comparing the contents of the first data packet and the second data packet in real time. When the first valid bit information and the second identification valid bit information are both valid, that is, when the first valid bit information 61012 of the first first data packet, the first valid bit information 61022 of the second first data packet, ..., the first valid bit information 62012 of the second second data packet, the second valid bit information 62022 of the second second data packet, ..., until the first valid bit information of all the first data packets and the second valid bit information of all the second data packets are valid, the first device status data and the second device status data are compared in sequence. That is, the first device status data 61011 of the first first data packet 6101 is compared with the first device status data 62011 of the first second data packet 6201, and the first device status data 61021 of the second first data packet 6102 is compared with the first device status data 62021 of the second second data packet 6202, ..., until the comparison of the first device status data of all first data packets and the second device status data of the second data packets is completed, and when the first device status data of the i-th data packet and the second device status data of the i-th data packet are different, a data packet inconsistency is recorded. For example, when the first device status data 33011 of the first data packet and the second device status data 33021 of the first second data packet are different, a data packet inconsistency is recorded. After the comparison of the contents of the first data packet and the second data packet is completed, the number of data packet inconsistencies is counted to obtain the number of data packet inconsistencies.

[0103] Figure 7 A flow chart of a train fault determination method according to another embodiment of the present disclosure is schematically shown.

[0104] like Figure 7 As shown, the train fault determination method of this embodiment includes operations S701 to S709.

[0105] In operation S701, when it is determined that the controller outputting the first data packet and the second data packet is of a single network port type, the data packet comparison rule is determined to be a second comparison rule.

[0106] In operation S702, a first data packet and a second data packet are received in real time.

[0107] In operation S703, it is determined whether the first valid bit information and the second valid bit information are valid. If yes, operation S704 is performed; if no, operation S709 is performed.

[0108] In operation S704, the first device status data and the second device status data are compared to determine device status difference information.

[0109] In operation S705, it is determined whether the communication cycle is the first communication cycle. If yes, operation S707 is performed, and if not, operation S706 is performed.

[0110] In operation S706, it is determined whether the number of inconsistent data packets is greater than a first quantity threshold. If yes, operation S708 is performed; if no, operation S709 is performed.

[0111] In operation S707, it is determined whether the duration of the data packet inconsistency is greater than a first time threshold. If yes, operation S708 is performed; otherwise, operation S709 is performed.

[0112] In operation S708, single network port type fault information is obtained.

[0113] In operation S709 , the subsystem of the single network port type has no fault.

[0114] According to an embodiment of the present disclosure, the train failure method also includes: when the first data packet and the second data packet of the train fault information representing a single carriage are inconsistent, determining that the faulty device of the train is a controller or a cable connector of the single carriage; when the first data packet and the second data packet of the train fault information representing multiple carriages are inconsistent, and the multiple carriages have the same network port type, determining that the faulty device of the train is the controller or cable of each of the multiple carriages; when the first data packet and the second data packet of the train fault information representing multiple carriages are inconsistent, and the multiple carriages have different network port types, determining that the faulty device of the train is a cable.

[0115] In one embodiment, the train may include multiple carriages. For example, the train may include 8 carriages.

[0116] In one embodiment, the cable connector can be connected to a switch to transmit data packets. When the fault information of the train indicates that the first data packet and the second data packet of a single carriage are inconsistent, the faulty device of the train is determined to be the controller or cable connector of the single carriage. That is, when the first data packet and the second data packet of only one carriage among multiple carriages in the train are inconsistent, the faulty device of the train can be determined to be the controller or cable connector corresponding to the single carriage.

[0117] For example, when the first data packet and the second data packet of only the third car among the eight cars are inconsistent, it can be determined that the faulty device of the train is the controller or cable connector corresponding to the third car.

[0118] According to an embodiment of the present disclosure, the cable represents the wires forming the train communication network. When the fault information of the train represents that the first data packet and the second data packet of multiple carriages are inconsistent, and the multiple carriages have the same network port type, it is determined that the faulty device of the train is the controller or cable of each of the multiple carriages, that is, when the first data packet and the second data packet of more than one carriage of the multiple carriages of the train are inconsistent, and the network port type of more than one carriage is the same, it can be determined that the faulty device of the train is the controller or cable of each of more than one carriage.

[0119] For example, when the first data packet and the second data packet of the 3rd car among 8 cars are inconsistent and the first data packet and the second data packet of the 6th car are inconsistent, it can be determined that the faulty equipment of the train is the controller or cable corresponding to the 3rd car and the 6th car.

[0120] According to an embodiment of the present disclosure, when the fault information of a train indicates that the first data packet and the second data packet of multiple carriages are inconsistent, and the multiple carriages have different network port types, it is determined that the faulty device of the train is a cable. That is, when the first data packet and the second data packet of more than one carriage are inconsistent, and the network port types of more than one carriage are not the same, it can be determined that the faulty device of the train is a cable.

[0121] For example, if the first data packet and the second data packet of the 5th carriage among 8 carriages are inconsistent, and the first data packet and the second data packet of the 6th carriage are inconsistent, and the 5th and 6th carriages have different network port types, it can be determined that the faulty equipment on the train is a cable.

[0122] According to the embodiments of the present disclosure, different train fault equipment can be determined based on the fault information of different trains, thereby reminding the train operation and maintenance personnel to investigate related problems, thereby avoiding the operation of the train with defects, and improving the operation safety of the train and the level of vehicle intelligence.
