[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0048] Figure 1 FIG. 1 is a flow chart of a synchronous processing method of a train unit fault process information provided by an embodiment of the present invention. Figure 1 As shown, the synchronous processing method of the EMU fault process information provided by the embodiment of the present invention includes:

[0049] Step S1: Generate fault task information according to the fault data packet of the EMU, obtain fault analysis data related to the fault task information, and extract data features and occurrence time corresponding to each type of data according to the fault analysis data.

[0050] Step S2: Determine the cause of the fault according to the data features of all categories of data and their occurrence time, synchronize the cause of the fault to the fault task information, and obtain the first fault synchronization information.

[0051] Step S3: Acquire the faulty component maintenance information of the EMU, synchronize the faulty component maintenance information with the first fault synchronization information, and obtain the second fault synchronization information.

[0052] In the above step S1, the device generates fault task information according to the fault data packet of the EMU, obtains fault analysis data related to the fault task information, and extracts data features and occurrence time corresponding to each type of data according to the fault analysis data. The device can be a computer device that executes the method. It should be noted that the acquisition and analysis of data involved in the embodiments of the present invention are authorized by the user.

[0053] The implementation process of the method of the present invention mainly includes three links, namely, fault information collection, fault data analysis and fault component information maintenance.

[0054] like Figure 2 As shown in the figure, fault information collection includes three steps: discovering fault codes, capturing fault information, and generating fault task information. The discovery of fault codes can be achieved by "manual reporting" or "WTDS data monitoring interface". After the fault code is discovered, the train operation condition information at the time of the fault is obtained from the WTDS system and EMIS system according to the train number and the time of the fault. Finally, the creation of the fault task is completed and the fault task information is generated. The fault task information includes the fault task ID.

[0055] like Figure 3 As shown in the figure, fault data analysis includes five steps: data acquisition, data analysis, data feature extraction, logic rule inversion and generation of analysis report. The acquired raw data is divided into remote data captured through the WTDS data interface and local data manually downloaded from the vehicle-mounted device. The raw data acquired in the first step is analyzed and processed in the second step to obtain the analysis data that can be used for subsequent analysis. The third step is to extract features from the analysis data for the next step of "logic rule inversion". The fourth step is to determine the cause of the fault according to the logic rules. The fifth step is to generate an analysis report based on the cause of the fault.

[0056] like Figure 4 As shown, the maintenance of faulty parts information includes three steps: capturing the faulty parts information replaced when handling faults from the supply chain execution system (SCE), then pairing the faulty parts with their corresponding fault tasks, and finally determining their failure categories and failure modes based on the analysis reports of the faulty parts.

[0057] The generating of fault task information according to the fault data packet of the EMU includes:

[0058] According to the pre-configured parameter name list and the fault data packet, the fault task information corresponding to each fault is extracted. The parameter name list is shown in Table 1:

[0059] Table 1

[0060]

[0061] The fault data packet includes a vehicle group number and a fault occurrence time, and the parameter name list includes a parameter data source corresponding to each parameter name one by one; accordingly, the fault task information corresponding to each fault is extracted one by one according to the pre-configured parameter name list and the fault data packet, including:

[0062] Acquire the fault parameter corresponding to the vehicle group number and the fault occurrence time from the parameter data source corresponding to each parameter name one by one;

[0063] Establish the corresponding relationship between multiple fault parameters corresponding to the same fault occurrence time, and obtain the fault task information corresponding to each fault. The description is as follows:

[0064] Taking the train speed in Table 1 as an example, the train speed value corresponding to the train set number and the time of fault occurrence is obtained from WTDS, that is, the train speed value of the current EMU at the time of fault occurrence can be obtained. The train speed value is used as one of the fault parameters for analyzing the cause of the fault.

[0065] Similarly, the control software version number, train outdoor temperature value, traction condition details, geographic information, mileage value, section (the starting and ending station names of the EMU operation) and train number information can be obtained.

[0066] The train speed value, control software version number, train outdoor temperature value, traction condition details, geographic information, mileage value, section and train number information are combined into multiple fault parameters, which can reflect the train operation condition information.

[0067] The time granularity of the fault occurrence time of the method of the present invention can be selected as a smaller value, such as seconds, so it can be considered that only one fault occurs at the same fault occurrence time, so each fault can be identified by the same fault occurrence time. The same fault occurrence time is recorded as tx, and the train speed value, control software version number, train outdoor temperature value, traction condition details, geographic information, mileage value, interval section and train number information corresponding to this moment are used as the fault task information corresponding to the fault. The fault task information can also further include the train group number & car number, fault code, fault occurrence time and fault task ID. The fault task ID can identify each fault task information.

[0068] The acquiring of the fault analysis data related to the fault task information includes:

[0069] Acquire remote data that can be used for fault analysis during the time period when the fault occurs and the data stored locally on the on-board equipment. Some data will be abnormal in a period of time before and after the fault occurs, and these abnormal data have a certain reference significance for fault analysis. For example, if the fault occurs at 9:20:10, 8:50:10 to 9:50:10 can be used as the time period when the fault occurs. Remote data can be obtained from WTDS, and on-board equipment can include but is not limited to all equipment on the EMU that can store local data. Remote data can be obtained through the network, and the data stored locally on the on-board equipment can be downloaded from the on-board equipment, and the obtained data can be stored in the database.

[0070] The extracting data features and occurrence time corresponding to each type of data respectively according to the fault analysis data includes:

[0071] Classify and store the fault analysis data according to different data formats;

[0072] Call the parsing algorithms and configuration files corresponding to different data formats to parse the classified stored data;

[0073] The data features and occurrence time corresponding to each type of data are extracted from the parsed data content.

[0074] The database classifies and stores the fault analysis data according to different data formats, and calls corresponding parsing algorithms and configuration files to parse the classified and stored data. The parsing algorithm is integrated in the software parsing kernel, and the configuration file is stored in the database.

[0075] Extract data features - time array from the parsed data content. Data features include but are not limited to: Boolean jump, analog range value, occurrence or recovery of a fault code, etc., as follows:

[0076] The data content includes different types of data, such as the running status of each train in the EMU controller. For a train running status quantity A which is a digital quantity, a jump from 0 to 1 and a jump from 1 to 0 can be defined. If A jumps from 0 to 1 at time t1, A jumps from 1 to 0 at time t2, and A jumps from 0 to 1 at time t3, then the data feature-time array can be recorded as {0-1(t1, t3); 1-0(t2)}.

[0077] For another train running status quantity B, which is an analog quantity, the range of the analog quantity can be defined as greater than 360 km / h and less than 180 km / h. If at t4, the speed of B changes from normal speed to 362 km / h, and then recovers to normal speed after processing; at t5, the speed of B changes from normal speed to 367 km / h, and then recovers to normal speed after processing; at t6, the speed of B changes from normal speed to 175 km / h, and then recovers to normal speed after processing, then the data feature-time array can be recorded as {>360(t4, t5); <180(t6)}.

[0078] In the above step S2, the device determines the cause of the fault according to the data features of all categories of data and their occurrence time, and synchronizes the cause of the fault to the fault task information to obtain the first fault synchronization information. The fault diagnosis logical relationship represented by the pre-built fault cause analysis decision tree can be used, and reverse reasoning can be performed according to the data features of all categories of data and their occurrence time to determine the cause of the fault.

[0079] The fault task information includes a fault task ID; accordingly, synchronizing the fault cause to the fault task information to obtain first fault synchronization information includes:

[0080] Determine a target fault task ID that identifies the cause of the fault, and synchronize the cause of the fault to the corresponding fault task information according to the target fault task ID to obtain the first fault synchronization information. When it is determined that the fault cause analysis of a fault task information is completed, the target fault task ID corresponding to the fault task information can be obtained, and the corresponding fault task information can be matched according to the target fault task ID, and the cause of the fault that has just been completed is synchronized to the fault task information with the same fault task ID to obtain the first fault synchronization information.

[0081] In the above step S3, the device obtains the faulty component maintenance information of the EMU, synchronizes the faulty component maintenance information with the first fault synchronization information, and obtains the second fault synchronization information. The faulty component maintenance information may specifically include the train number, fault code, fault occurrence time, and material maintenance information, and the material maintenance information specifically includes the material number and serial number of the disassembled material, and the material number and serial number of the replacement material, wherein the material number may identify which type of material, and the serial number may identify which batch of materials in this type of material.

[0082] The step of synchronizing the fault component maintenance information with the first fault synchronization information to obtain second fault synchronization information includes:

[0083] Determine the target vehicle group number, target fault code and target fault occurrence time that identify the current fault part maintenance information, and synchronize the target material maintenance information corresponding to the current fault part maintenance information to the first fault synchronization information according to the target vehicle group number, the target fault code and the target fault occurrence time, to obtain the second fault synchronization information. Since the maintenance staff needs to continuously maintain the fault part, each time the maintenance is completed, the fault part maintenance information of that time is used as the current fault part maintenance information.

[0084] The target train set number, target fault code and target fault occurrence time are used as matching factors. The first fault synchronization information corresponding to the current faulty part maintenance information can be determined based on the same matching factors in the first fault synchronization information. The above target material maintenance information, that is, the material number and serial number of the disassembled material and the material number and serial number of the replacement material, are synchronized to the above first fault synchronization information. At this point, the second fault synchronization information integrates the fault task information, the cause of the fault and the faulty part maintenance information. Subsequently, the EMU fault analysis and troubleshooting work can be realized based on the second fault synchronization information.

[0085] The fault task ID can be used to query the maintenance information of the faulty part in one click. Furthermore, the quality engineer can fill in the "failure category" and "failure mode" of the faulty part according to the failure analysis conclusion of the faulty part.

[0086] The synchronous processing method of EMU fault process information provided by the embodiment of the present invention has the following beneficial technical effects:

[0087] 1. It can realize automatic discovery of EMU faults, automatically capture WTDS and EMIS data, create fault analysis tasks, and improve the management efficiency and standardization of fault information;

[0088] 2. It integrates all links in the fault data analysis process, including data acquisition, data analysis, feature extraction and rule inversion, improving the standardization of data management and the automation level of the analysis process;

[0090] 4. Research and classification of failure types and failure modes of faulty parts will help improve the understanding of failure patterns and fundamentally eliminate potential failure hazards.

[0092] Furthermore, generating fault task information according to the fault data packet of the EMU includes:

[0093] According to the pre-configured parameter name list and the fault data packet, the fault task information corresponding to each fault is extracted.

[0094] Further, the fault data packet includes a vehicle group number and a fault occurrence time, and the parameter name list includes a parameter data source corresponding to each parameter name one by one; accordingly, the fault task information corresponding to each fault one by one is extracted according to the pre-configured parameter name list and the fault data packet, including:
