S201: Obtain a fault problem of the locomotive, and generate a corresponding fault content list.

Specifically, the train control and management system TCMS (Train Control and Management System) for electric locomotives implements the locomotive fault diagnosis function, and the fault problem of the locomotive can be obtained through the fault processing system of the electric locomotive. In an optional embodiment, Failure problems include locomotive system failure problems and related component failure problems, see Table 1 below for details.

Table 1

In an alternative embodiment, even if the locomotive is powered off or the battery is removed, the recorded data about the fault storage will be saved. According to the fault history, the faults are sorted according to a certain entry format, and the corresponding fault content list is generated. Among them, the fault content list includes fault code, fault type, and time of occurrence.

The fault code composition can be preset as: XX-YY-ZZ, and the coding rules are shown in Table 2 below.

Table 2

The logic control of the failure problem of the whole vehicle system is realized by the functional logic software in the central control unit MPU. That is, it can be realized through the following steps. For details, see step S202 and step S203 below.

S202: Perform fault configuration according to the fault content list, record the fault content list in the fault history parameter, and obtain the fault context;

Specifically, according to the matching of the fault code with the historical fault code in the preset record library, the fault history parameter corresponding to the fault problem is obtained, and the fault content list is imported into the fault history parameter to obtain the fault context. Among them, the fault history parameters include fault processing time, fault record update cycle, and operating data before the fault is triggered.

In an optional embodiment, the development of fault problem control through the integrated development library of Matlab/Simulink may include two library modules: a fault configuration module and a fault recording module.

Refer to Figure 3, which is a schematic diagram of the effect of the method for handling electric locomotive faults provided by Embodiment 1 of the present invention. The fault content list is loaded into the fault configuration module by one-click import. After importing, all fault content lists can be displayed in the fault configuration module. Called in the recording module.

In an optional embodiment, the fault record module is set in a preset record library, so that the fault content list and the fault history parameters are recorded and stored after the fault problem is triggered. For example, refer to FIG. 4, which is a schematic diagram of the recording effect after the electric locomotive fault problem is triggered according to the first embodiment of the present invention.

After the fault record module is turned on and run, the fault configuration is performed, and the specific fault code is matched with the historical fault code. The extension code, main code, and sub-code of the fault code are matched. After the matching is successful, the fault history parameters corresponding to the fault problem are obtained. , And automatically import the fault content list into the fault history parameters to obtain the fault context. Among them, the fault context refers to the relevant operating data before and after the trigger of the fault problem.

S203. Determine a fault protection measure corresponding to the fault problem according to the fault context.

Specifically, at least one faulty component corresponding to the fault problem is obtained according to the fault context, and the fault protection measures corresponding to each faulty component are sequentially determined. In an optional embodiment, the whole vehicle fault problem is divided into seven systems according to logical functions, and each system can realize fault recording and fault configuration after triggering the fault problem; and then obtain the fault protection measures corresponding to the fault problem. Realize the automatic protection action after the fault problem is triggered. Each system contains multiple components, and the output actions of each system fault protection measure are sorted and classified, which can be divided into main disconnection, prohibition of main disconnection, pantograph reduction, traction lockout, electrical lockout, and isolation TCU, isolated ACU. For example, after the protection action signal is output, the main break command corresponding to the fault problem causes the main break control component to output the main break command.

In this embodiment, the fault problem "main disconnection and engagement" is taken as an example to build fault problem control development in Matlab/Simulink. When the fault problem is triggered, perform the fault configuration according to the fault content list, record the fault content list in the fault history parameters to obtain the fault context: main disconnection command, main disconnection status, fault reset, etc. And the update cycle of each fault history parameter record is 100ms, it can update the record 1000ms before the fault problem is triggered, and update the record 1000ms after the fault problem is triggered. Then diagnose and analyze the fault problem according to the fault context. Furthermore, after the fault problem is triggered, the MPU needs to output the fault protection measures. The output action logic of the fault protection measures corresponding to the fault problem "main disconnection and engagement" is shown in FIG. 5, which is the electric locomotive fault problem provided by the first embodiment of the present invention. Schematic diagram of the treatment effect.

The MPU outputs the "main shutdown signal" to the traction control component TCU (Transmission Control Unit, automatic transmission control unit), auxiliary control component ACU (Auto Controled Unite, automatic control unit), TCU, ACU perform traction system and auxiliary system shutdown Main break fault protection measures. After 200ms, the MPU outputs the "main break command" to the remote input and output unit RIOM, and at the same time issues the "prohibit close main break command".

In an optional embodiment, each faulty component in the main loop fault system and the corresponding fault protection measures are encapsulated to form a fault protection measure corresponding to the main loop fault problem.

In this embodiment, the electric locomotive vehicle control and management system TCMS realizes the locomotive fault diagnosis function, monitors the status of the locomotive operation process, quickly identifies and locates various faults, so as to obtain the real-time fault protection measures for the whole vehicle. , Obtain the analysis results of each faulty component corresponding to the fault problem. In addition to automatically disconnecting the power supply, it can also prompt the driver to take fault protection measures such as isolating the faulty component and reducing the operating power for each faulty system component to ensure the safety of the train. Operate reliably.

In an optional embodiment, the fault problem is divided into a first-level fault and a second-level fault according to the fault protection measures, where the first-level fault includes the initial stoppage of the locomotive and the operation of the locomotive after the driver takes the fault protection measures. Faults; second-level faults include other faults except for first-level faults; first-level faults have a higher priority than second-level faults. The handling of specific fault problems is mainly divided into five types: pulse blockade, isolation, disconnection of VCB (not forbidden), lowering the pantograph, and prohibiting starting/running. As shown in Figure 6. FIG. 6 is a schematic diagram of the effect of packaging the fault protection measures for electric locomotives provided by Embodiment 1 of the present invention.

Combining the above example of "main disconnection and engagement", the control analysis of the failure problem in the main circuit failure system and the corresponding failure protection measures are packaged to form an overall solution to the main circuit system failure problem.

In an optional embodiment, the fault content list, fault context, and fault protection measures are presented through the host computer interface, and at least one reminder message is sent to the locomotive driver.

For example, the entire vehicle fault problem control compilation generates an executable file, which can be downloaded to the central control unit MPU through the host computer interface. In an optional embodiment, the central control unit MPU (microprocessor uint, microprocessor unit) Set in the local server, the fault content list, fault context, and fault protection measures can be presented through the host computer interface, and the fault protection measures corresponding to the fault problem can be sent to the locomotive driver. For example, if the fault problem corresponds to multiple faulty components, it can be sent to the locomotive driver. The locomotive driver sends a reminder message for each faulty component to ensure the safety and reliability of the locomotive. The reminder message can include voice, text, image/video, and so on. This embodiment does not specifically limit the reminder message.

In an optional embodiment, the method further includes: performing offline diagnosis and analysis by downloading the fault content list and the fault context to determine the fault protection measures corresponding to the fault problem.

In an optional embodiment, the fault content list and fault context can be downloaded to the target machine and displayed in Excel format. And perform offline diagnosis and analysis to determine the fault protection measures corresponding to the fault problem. For example, it is determined through analysis that after the main break command is issued, the main break continues to be in the closed state, which leads to the occurrence of the fault problem.
