Description

Technical Field

[0001] The present application relates to the technical field of locomotive information processing, and in particular to a method and device for locomotive data processing. Background Art

[0002] Existing locomotive data inspection methods rely on data analysis based on message log files (i.e., *.TXT files) displayed on the driver display unit (DDU). Typically, data analysts can only board the locomotive after the locomotive returns to the depot. They download the corresponding event log files through the DDU's USB port. Ground-based analysis software then filters, analyzes, and processes them to locate locomotive faults and event log information. Furthermore, existing event log files only record event information at the fault point, omitting the locomotive's operating status and key data at the time of the fault. This makes it difficult to provide effective early warning information and hinders full lifecycle locomotive quality monitoring. Summary of the Invention

[0087] A first aspect of an embodiment of the present application provides a method for data processing for a locomotive, comprising:

[0088] Acquire message event data on the FIP bus of the locomotive, each piece of the message event data including at least one event code;

[0089] Matching the event code with a constant fault code of the locomotive, wherein the constant fault code is a pre-set code of a common fault;

[0090] When the event code matches the constant fault code, the message event data corresponding to the event code is parsed, and the parsing result is stored as an event recording process file.

[0091] Example 1

[0092] Figure 1 This is a flow chart of the method of Example 1 of the present application.

[0093] like Figure 1 Specifically, a method for processing data for a locomotive includes:

[0094] Step 110: Acquire message event data on the FIP bus of the locomotive, each piece of the message event data includes at least one event code.

[0095] Step 120: Match the event code with a constant fault code of the locomotive, where the constant fault code is a pre-set code of a common fault.

[0096] Step 130: When the event code matches the constant fault code, the message event data corresponding to the event code is parsed, and the parsing result is stored as an event recording process file.

[0097] Acquiring the message event data on the FIP bus of the locomotive in step 110 refers to obtaining the message event data transmitted between the communication ports on the locomotive through the locomotive FIP bus. In this embodiment, each message event data includes an event code uniquely corresponding to the message event data.

[0098] In steps 120-130, the event code is matched with the locomotive's constant fault code. When a match is found between the event code and the constant fault code, the message event data corresponding to the event code is parsed, and the parsing results are stored as an event record file. This refers to the process of filtering message event data using constant fault codes. The pre-set common fault codes, for example, are based on past experience, with 100 common fault codes set as constant fault codes. These 100 common fault codes can then be used to filter out, from a large amount of message event data, message event data whose event codes match the constant fault codes.

[0099] Parsing the message event data corresponding to the event code means encapsulating and storing the message event data in a required data format through parsing. In this embodiment, the event recording process file is optionally stored as a CSV file.

[0100] This embodiment acquires message event data from the FIP bus, matches the event codes in the message event data with constant fault codes, parses and encapsulates the message event data filtered out after a match, and stores it as an event record process file. This advantageously allows for preliminary analysis of message event data to be completed en route, reducing the time required for post-station data analysis and thus preventing delays in the locomotive's normal departure. Furthermore, this significantly reduces the amount of data ultimately required for analysis, similarly saving time for post-station data analysis. Furthermore, it enables the locomotive to process more data en route, preventing the excessive accumulation of message event data during transit.

[0101] The process of acquiring, parsing, and storing message event data in this embodiment is optionally completed through the following steps.

[0102] Get the device name and device version number in the message event data and associate them with the corresponding data folder, which is built into the device.

[0103] Find the evt_evt file in the corresponding folder, which stores all event-related information of the corresponding device.

[0104] According to the event code in the message event data, find the evt_ctx file in the same directory and retrieve the context feature variable corresponding to the context feature variable number contained in it;

[0105] The event log process file is stored in plain text in the CSV file format, which is a comma-separated value file format.

[0106] In some embodiments, the message event data also includes a locomotive number, a device name, a device version number, a message time, a number of occurrences, and corresponding multiple Context feature variable numbers.

[0107] The device name is, for example, a code that includes a device number or code and can uniquely identify the device on the locomotive, and the device version number refers to the version number of the software currently running on the device.

[0108] In some embodiments, before matching the event code with the constant fault code of the locomotive, the method further includes encapsulating the message event data according to a predetermined first data format, and storing the encapsulation result as an event record original file.

[0109] The original event record file can optionally be stored as a TXT file. It is encapsulated according to a predetermined first data format, which in this embodiment refers to the TXT file format. That is, all message event data is encapsulated into an original event record file according to the TXT file format. For example, when the message event data includes multiple information elements such as locomotive number, device name, device version number, message time, number of occurrences, and event code, the above-mentioned data encapsulation process is to encapsulate these multiple information elements into an original event record file in the TXT file format. Of course, the inventive concept of this application is not limited to this. The first data format can also be other data formats commonly used by those skilled in the art to save original event record files. In this embodiment, this encapsulation and storage process can optionally be completed by creating three threads, which are respectively used for real-time updating of FIP data, obtaining message event data, and encapsulating message data.

[0110] The specific steps include:

[0111] Define the logical port queue by initialization;

[0112] Initialize the message event data queue;

[0113] Instantiate the FIP object, including setting the FIP class instantiation object parameters;

[0114] Start the FIP data real-time update thread;

[0115] Start the message event data acquisition thread;

[0116] Start the message event data encapsulation thread.

[0117] Example 2

[0118] Figure 2 This is a flow chart of the method of Example 2 of the present application.

[0119] like Figure 2 Specifically, a method for processing data for a locomotive includes:

[0120] Step 110: Acquire message event data on the FIP bus of the locomotive, each piece of the message event data includes at least one event code.

[0121] Step 120: Match the event code with a constant fault code of the locomotive, where the constant fault code is a pre-set code of a common fault.

[0122] Step 130: When the event code matches the constant fault code, the message event data corresponding to the event code is parsed, and the parsing result is stored as an event recording process file.

[0123] Step 140: Acquire the operating status data on the FIP bus of the locomotive, where each piece of the operating status data includes at least an analog quantity, digital quantity or context feature variable recorded in real time by a device of the locomotive.

[0124] Step 150: When the analog quantity, digital quantity or context characteristic variable exceeds the corresponding set threshold, a status alarm message is issued.

[0125] Different from Example 1, Example 2 further includes step 140 and step 150.

[0126] In step 140, the operating status data on the FIP bus of the locomotive is obtained, wherein the analog quantity, digital quantity or context characteristic variable can be a value representing the temperature, pressure or speed of the equipment operating condition. Each value has a corresponding preset threshold value. For example, the locomotive total air cylinder pressure threshold is 1000kPa.

[0127] In step 150, when the analog quantity, digital quantity, or context feature variable exceeds the corresponding set threshold, a status alarm message is issued. For example, if the total air cylinder pressure threshold of a locomotive is 1000kPa, then when the total air cylinder pressure value included in the operating status data of the device exceeds 1000kPa, the alarm unit will be triggered to issue a status alarm message.

[0128] This embodiment further obtains the operating status data on the FIP bus of the locomotive, thereby realizing real-time analysis and warning of the locomotive on the way, predicting the fault status in advance, and reducing the failure rate of standby locomotives.

[0129] In some embodiments, the method further comprises:

[0130] The operating status data is encapsulated according to a predetermined second data format, and the encapsulation result is stored as a driving record original file. The locomotive driving record file is optional in this embodiment and is stored as a BIN file. In the process of encapsulating according to the predetermined second data format and storing the encapsulation result as the driving record original file, the second data format in this embodiment refers to the BIN file format, that is, the operating status data is encapsulated and stored according to the BIN file format. The process of encapsulation and storage is similar to the process of encapsulating and storing the message event data according to the first data format mentioned above, except that the encapsulation and storage of the operating status data is periodic, while the encapsulation and storage of the message event data is performed randomly at any time.

[0131] In some embodiments, the method further comprises:

[0132] Context feature variables whose numbers correspond to the constant fault code are screened from the context feature variables, a predetermined number of context feature variables before and after the occurrence of the screened context feature variables are packaged according to a predetermined third data format, and the packaged result is stored as a fault feature variable on-demand file. In this embodiment, the fault feature variable on-demand file is optionally stored as an FLT file.

[0133] In some embodiments, the method further comprises:

[0134] The event record original file, the event record process file, the driving record original file, the fault characteristic variable on-demand file, the alarm information, the axle report data file and the video data file are packaged.

[0135] The comprehensive data package is uploaded to the cloud data platform of the locomotive via a wireless communication network.

[0136] In this implementation, the comprehensive data package is uploaded to the cloud data platform of the locomotive through the wireless communication network, which can effectively avoid the heavy workload of the staff caused by downloading data through the USB interface. In the case of frequent use of the USB port, it is easy to cause interface failure and the data download work cannot be completed within the short time when the locomotive enters the station.

[0137] Specifically, in some embodiments, uploading the comprehensive data packet to the cloud data platform of the locomotive via the wireless communication network includes:

[0138] A VPN virtual channel is established between the 4G module and the cloud data platform, so that the cloud data platform can receive the alarm information in real time, or receive on demand any one or a combination of multiple files among the event record original file, the event record process file, the driving record original file and the fault feature variable on-demand file.

[0139] In this implementation, a VPN virtual channel is established between the 4G module and the cloud data platform. The cloud data platform can receive alarm information in real time or on-demand, including any one or a combination of the original event log file, the event process log file, the original driving log file, and the on-demand fault signature variable file. Fault conditions can also be predicted in advance, allowing for real-time analysis and early warning during transit, providing more timely data support for fault analysis and reducing the failure rate of standby locomotives.

[0140] Specifically, in some embodiments, the method further includes:

[0141] After the locomotive enters the station, the event record original file, the event record process file, the driving record original file and / or the fault feature variable on-demand file are automatically uploaded to the cloud data platform through the 5G communication module.

[0142] After the locomotive enters the station, the original file of the event record is automatically uploaded through the 5G communication module. This means that when it is difficult to transmit some large numbers of files through the 4G module on the way, just after the locomotive enters the station, the high bandwidth and high speed of 5G are utilized, but it will be limited by the transmission distance, and the large number of files will be automatically uploaded through the 5G communication module at the station.
