Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of railway transportation, and particularly relates to an intelligent assistant software system for a motor train unit and a fault diagnosis and disposal method thereof. BACKGROUND

[0002] In the field of railway transportation developing at a high speed today, motor train units have become an important means of transport for long-distance travel due to their high efficiency, convenience and comfort. However, the improvement of the quality of motor train unit operation and maintenance is facing many challenges, one of which is the uneven fault disposal capability, which is one of the key factors restricting the improvement. The fault disposal lag phenomenon caused by this problem is increasingly prominent and has brought a series of negative effects on the railway transportation order.

[0003] In the operation and maintenance of high-speed rail motor train units, the fault diagnosis of Fuxing motor train units faces many challenges: (1) There are many fault codes, and it is difficult for technicians to master them all, resulting in long time-consuming and easy-to-make mistakes in fault positioning; (2) Fault information is scattered in multiple systems, and there is a lack of an integrated platform, resulting in low query efficiency; (3) Maintenance guidance relies on paper manuals or non-associated electronic data, which is not easy to quickly respond to real-time operation data; (4) In the remote fault scenario, ground personnel cannot real-time view the status inside the train, which increases the response delay and safety risk.

[0004] The existing technologies such as independent HMI simulation software or fault management system have limitations: first, the modules are islanded and lack intelligent interoperation; second, the data processing capability is weak and the on-board data cannot be efficiently converted into a visual interface; third, it cannot integrate the whole process management of emergency communication and operation limitation. Although there is a remote monitoring system, it focuses on data acquisition rather than the integration of ground application for Fuxing. Therefore, an integrated software solution is urgently needed to realize the integrated processing of fault diagnosis, maintenance guidance and safety monitoring. SUMMARY

[0005] The purpose of the present application is to overcome the problems of weak data capability and weak visual interface conversion capability of the existing system, and to provide an intelligent assistant software system for a motor train unit and a fault diagnosis and disposal method thereof.

[0006] In order to achieve the above purpose, the present application adopts the following technical solutions: In a first aspect, the present application provides an intelligent assistant software system for a motor train unit, which comprises a central control unit and a functional module connected thereto, and the functional module comprises: An HMI guidance module for real-time acquisition and display of operation data of the motor train unit, providing menu operation guidance and training functions for the HMI screen of the motor train unit; The fault code query module is configured to parse the fault information displayed by the HMI guide module, automatically identify and extract the fault code therefrom, and query the corresponding fault detailed information in a preset fault database based on the identified fault code.

[0010] In the step of automatically matching the repair standard and dynamically generating the fault disposal scheme based on the queried fault detailed information, according to the fault severity, the historical disposal success rate and the maintenance window time information, the optimal fault disposal scheme is automatically generated by a decision rule engine.

[0011] In the step of obtaining the spatial positioning information of the fault component according to the requirement during the disposal process, the spatial positioning information of the fault component is obtained by using the digital three-dimensional model of the EMU.

[0020] Example 1 A motor train unit intelligent assistant software system, comprising a central control unit and a functional module connected thereto, the functional module comprising: An HMI guiding module for acquiring and displaying operation data of the motor train unit in real time, providing menu operation guidance and training function of the HMI screen of the motor train unit; A fault code query module for analyzing fault information displayed by the HMI guiding module, automatically identifying and extracting fault codes therein, and querying corresponding fault detailed information in a preset fault database based on the identified fault codes; A work maintenance guide module for automatically calling corresponding maintenance standards according to the detailed information of the fault, and dynamically generating a fault treatment scheme; An emergency fault handling module is configured to implement fault handling according to a fault handling scheme and corresponding repair standards; A device arrangement module is configured to provide spatial positioning information of a fault component related to the fault information for the emergency fault handling module; An electrical principle module is configured to provide circuit connection relationships and technical parameters of the fault component; A material query module is configured to generate a fault component replacement list based on the obtained spatial positioning information, circuit principle and technical parameters of the fault component; A torque standard module is configured to obtain torque requirements for disassembling and assembling the replacement fault component; An emergency response module is integrated with the fault code query module to automatically trigger an information reporting process conforming to the fault level.

[0021] Specifically, the HMI guidance module is configured to obtain real-time operation data of the EMU and display, so that the relevant information of the EMU can be directly viewed, including a traction interface, a braking interface, a device state, a device control, a low constant speed, fault information, a running interface, and a maintenance page. The HMI guidance module is used for fault simulation, information viewing, personnel training and drilling. The page displays information such as time, speed, braking level, fault information, main control signal, direction signal, network voltage, traction auxiliary converter state, door state, and network flow. By converting data signals into corresponding numerical values or icons displayed on the page, the current EMU state information is intuitively displayed, which facilitates the accuracy of remote fault guidance.

[0032] There are many accessories in the motor train unit. In order to distinguish each accessory, when the motor train unit is shipped, a unique material code is set for each accessory according to the relevant numbering rules. The material query module can query the material code of each component of the motor train unit, and the matching material code can be quickly queried by the component name, and the material code is used for material taking, so as to improve the fault disposal efficiency.
