[0040] Figure 3 This is a schematic diagram of the structure of a network system provided by the present invention. Detailed Implementation

[0041] The core of this invention is to provide a fault location method, system, network system, and train for trains, which can identify the data collection point where the fault occurs or the train line is broken, so as to facilitate subsequent processing by the staff.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The vehicle network system, traction system, and braking system all collect the status of key hard-line signal train tracks, including emergency braking tracks, rapid braking tracks, braking tracks, and traction tracks. Simultaneously, the network system transmits the track status to the traction and braking systems via communication. When the traction and braking systems detect a discrepancy between the track status detected and the data sent by the network system, they report a related inconsistency fault. This method cannot accurately pinpoint the fault location, requiring manual troubleshooting, which is slow and affects vehicle operation.

[0044] Figure 1 A flowchart of a train fault location method provided by the present invention, the method comprising:

[0045] S11: Determine whether the number of collection points communicating with the network system exceeds the preset number; if so, proceed to step S12.

[0046] Multiple data collection points are set up on the train. The network system of this application serves as one of these collection points, communicating with other collection points on the train. The number of collection points communicating with the network system indicates the number of collection points in normal working condition. If the number of collection points does not exceed a preset number, it indicates that the train may not have fully started yet, and it is necessary to wait for all collection points to start. If the number of collection points communicating with the network system exceeds the preset number, it means that the train has started successfully, and all collection points are functioning normally, allowing for further assessment.

[0047] S12: Determine whether the status of the train line collected by the collection point is consistent; if not, if there is one collection point whose status of the train line collected by other collection points is inconsistent, proceed to step S13; if there are multiple collection points whose status of the train line collected by other collection points is inconsistent, proceed to step S14.

[0048] The type and location of the train malfunction are determined based on the status of the train track collected from the data collection points.

[0049] If there are ten data collection points, and the train track status collected by one data collection point is inconsistent with the train track status collected by the other nine data collection points, then there is currently one data collection point with inconsistent train track status with the other data collection points, and proceed to step S13. If there are ten data collection points, and the train track status collected by three data collection points is inconsistent with the train track status collected by the other seven data collection points, then there are currently multiple data collection points with inconsistent train track status with the other data collection points, and proceed to step S14.

[0050] Specifically, the status of a train line refers to whether the signal represented by that train line is valid. For example, if the train line is a braking train line, then the current status of the train line includes whether there is a braking signal or not. If nine data collection points collect data showing that the train line has a braking signal, while one data collection point collects data showing that there is no braking signal, then the train line status collected by the current data collection points is inconsistent.

[0051] S13: Determine if a data collection point has malfunctioned and report an error;

[0052] If the status of the train track collected by only one collection point is inconsistent with the status of the train track collected by other collection points, it is often because that collection point is faulty. The network system will report an error to the train driver's cab, indicating that the status collected by that collection point is incorrect. The driver can then determine that the fault is located at that collection point.

[0053] S14: Determine if a line breakage fault has occurred on the train track and report the error.

[0054] If the train track status collected by multiple data acquisition points is inconsistent with the status collected by other data acquisition points—for example, if three data acquisition points show inconsistent train track statuses with other data acquisition points—it indicates a breakage fault in the train track, meaning the signal line has broken somewhere. This would cause the incorrect train track statuses collected by multiple data acquisition points. It should be noted that if three data acquisition points show inconsistencies, these three data acquisition points are usually three consecutive data acquisition points.

[0055] This application provides a train fault location method applied in the field of detection. It determines whether the number of data collection points communicating with the network system exceeds a preset number. If the number of data collection points exceeds the preset number, it determines whether the train track status collected by the data collection points is consistent. If the train track status collected by one data collection point is inconsistent with that collected by other data collection points, a fault is determined at that data collection point, and an error is reported. If the train track status collected by multiple data collection points is inconsistent with that collected by other data collection points, a train track breakage fault is determined, and an error is reported. When the number of data collection points exceeds the preset number, the train startup is completed. By using the network system to determine whether the train track status collected by multiple data collection points is consistent, and by determining the number of inconsistent data collection points, the faulty data collection point or the train track breakage fault is identified, facilitating subsequent processing by personnel.

[0056] Based on the above embodiments:

[0057] As a preferred embodiment, before determining whether the number of collection points communicating with the network system exceeds a preset number, the method further includes:

[0058] The number of data collection points communicating with the network system is determined. The total number of data collection points is the sum of the number of network systems, traction systems, and braking systems of the train.

[0059] Taking a six-car train as an example, it includes two network systems, four traction systems, and four braking systems, totaling ten data collection points. Each network system needs to determine the number of data collection points communicating with it, and each system needs to determine the number of data collection points communicating with it. Assuming all data collection points are connected normally, if there are ten data collection points in total, then nine data collection points communicate with the network systems. Adding the data collection points itself, there are a total of ten data collection points for the train line status.

[0060] The data collection points are set on the corresponding network system, traction system, or braking system. Each system has one or more data collection points, and the specific number of points is set according to actual needs.

[0061] The network system continuously determines the number of collection points for expected communication. When the number exceeds the preset number, it begins to make subsequent judgments.

[0062] As a preferred embodiment, determining whether the train track status collected by the collection point is consistent includes:

[0063] Determine whether the statuses of the emergency braking train line, the rapid braking train line, the braking train line, and the traction train line collected from the data collection point are consistent.

[0064] The train tracks consist of four lines: an emergency braking train track, a rapid braking train track, a braking train track, and a traction train track. The data collection points are used to collect the status of these four train tracks.

[0065] Specifically, the data acquisition points are used to detect whether the train lines are at a high or low voltage level. The emergency braking train lines, rapid braking train lines, and regular braking train lines are active low, while the traction train lines are active high. The status of the train lines is determined by detecting whether they are at a high or low voltage level.

[0066] Each data collection point collects the status of four train lines and sends it to the network system. The network system itself... Collect the status of the train line.

[0067] As a preferred embodiment, after determining whether the number of collection points communicating with the network system exceeds a preset number, the method further includes:

[0068] If the number of data collection points does not exceed the preset number, it will not be determined whether the train line has a fault.

[0069] When the number of data collection points does not exceed the preset number, the train may not be officially running and may be in the startup process. Therefore, it is unnecessary to collect data on the status of the train line at this time, and it cannot serve as a basis for judging the status of the train line. So, when the number of data collection points does not exceed the preset number, it is not determined whether the train line has a fault. Only when the number of data collection points exceeds the preset number will a judgment be made.

[0070] As a preferred embodiment, after determining whether the train track status collected by the collection point is consistent, the method further includes:

[0071] If the status of the train track collected from all data collection points is consistent, then the train track is determined to be fault-free.

[0072] If the status of the four train tracks collected by all the collection points is consistent, it proves that the train tracks are not broken and each collection point is working normally. Therefore, the train tracks are not faulty and no error is reported.

[0073] As a preferred embodiment, if the train track status collected by one data collection point is inconsistent with that collected by other data collection points, then one data collection point is determined to be faulty and an error is reported, including:

[0074] If the status of the train line collected by one data collection point is inconsistent with that collected by other data collection points, and the duration exceeds the preset time, then a data collection point is determined to be faulty and an error is reported.

[0075] Since the train tracks are solid wires, signal transmission takes time, resulting in a delay during data acquisition. If the acquired train track statuses are inconsistent, a preset time must be waited before making a judgment; this will lead to a more accurate result.

[0076] As a preferred embodiment, after reporting the error, the method further includes:

[0077] The status of the train line is collected through a connector at the collection point, which is located between two collection points.

[0078] If the status of the train line collected by the connector is consistent with the status of the train line collected by other collection points, it is determined that the connector is loose or has poor contact.

[0079] The connector is used to connect two acquisition points. When the status of the train line acquired by the connector is consistent with the status of other acquisition points, it proves that the status of the train line is normal when it is transmitted from the adjacent acquisition point to the connector. However, if the status of the train line acquired by this acquisition point is different from that of other acquisition points during the transmission process from the connector, it indicates that there may be a problem with the connector itself. It may be that the connection between the connecting cable and the acquisition point is loose or has poor contact, which causes the status of the train line acquired by this acquisition point to be inconsistent with that of other acquisition points.

[0080] As a preferred embodiment, after acquiring the status of the train line through the connector at the acquisition point, the method further includes:

[0081] If the status of the train track collected by the connector is inconsistent with the status of the train track collected by other collection points, it is determined that there is a fault in the network system, traction system or braking system corresponding to the collection point.

[0082] If the status of the train line collected by the contactor is inconsistent with the status of the train line collected by other collection points, it can be proven that the current collection point has a fault, which has caused the inconsistent status of the train line collected by the connector connected to it. Therefore, it is determined that the network system, traction system or braking system corresponding to the collection point has a fault.

[0083] As a preferred embodiment, determining that a train track has experienced a broken wire fault and reporting an error includes:

[0084] The location of the disconnection fault was determined based on the locations of multiple data collection points;

[0085] The system determines that a line breakage fault has occurred on the train track and reports the location of the fault.

[0086] Taking the collection of emergency braking train lines at five collection points as an example, if the results collected from the first three collection points are different from those collected from the last two collection points, it indicates that a line breakage fault has occurred between the third and fourth collection points. The report that the emergency braking train line has a line breakage fault and that the fault location is between the third and fourth collection points should be reported to the driver's cab so that the driver can understand.

[0087] It should be noted that if a fault occurs, it will not occur at the first or third data collection point. That is, if multiple data collection points have different faults, the faulty data collection points will be consecutive.

[0088] Figure 2 This is a schematic diagram of a train fault location system provided by the present invention. The train fault location system includes:

[0089] The first judgment unit 21 is used to determine whether the number of collection points communicating with the network system exceeds the preset number; if so, the second judgment unit is triggered.

[0090] The second judgment unit 22 is used to determine whether the status of the train line collected by the collection point is consistent; if there is a collection point whose status of the train line collected by other collection points is inconsistent, the first judgment unit is triggered; if there are multiple collection points whose status of the train line collected by other collection points is inconsistent, the second judgment unit is triggered.

[0091] The first determination unit 23 is used to determine that a collection point has malfunctioned and to report an error.

[0092] The second determination unit 24 is used to determine if a line breakage fault has occurred on the train track and to report the error.

[0093] Specifically, it also includes:

[0094] The first determining unit is used to determine the number of collection points that communicate with the network system. The total number of collection points is the sum of the number of network systems, the number of traction systems, and the number of braking systems of the train.

[0095] The first judgment unit 21 is specifically used to determine whether the states of the emergency braking train line, the fast braking train line, the braking train line and the traction train line collected by the collection point are consistent.

[0096] The non-determination unit is used to determine whether a fault has occurred on the train line when the number of collection points does not exceed a preset number.

[0097] The third determination unit is used to determine that the train line is fault-free when the status of the train line collected from all collection points is consistent.

[0098] The first determination unit 23 is specifically used to determine that a collection point has malfunctioned and to report an error if the status of the train line collected by one collection point is inconsistent with that collected by other collection points and the duration exceeds a preset time.

[0099] The second determining unit is used to determine the location of the disconnection fault based on the locations of multiple acquisition points;

[0100] The second determination unit 24 is specifically used to determine if a line breakage fault has occurred on the train line and to report the location of the line breakage fault.

[0108] If the train track status collected by one data collection point is inconsistent with that collected by other data collection points, then one data collection point is determined to be faulty and an error is reported.

[0109] If multiple data collection points show inconsistent train track status with other data collection points, it is determined that a train track breakage fault has occurred, and an error is reported.

[0110] Before determining whether the number of data collection points communicating with the network system exceeds the preset number, the following steps are also taken:

[0111] The number of data collection points communicating with the network system is determined. The total number of data collection points is the sum of the number of network systems, traction systems, and braking systems of the train.
