Description

Technical Field

[0001] This disclosure relates to the field of testing technology, and in particular to a method, apparatus and system for equipment operation and maintenance, storage medium and program product. Background Technology

[0002] Existing after-sales service for equipment mainly includes two types. The first type involves after-sales service personnel regularly maintaining and servicing the target equipment, inspecting it according to the established inspection and maintenance items, and addressing any potential problems found. The second type involves customers reporting repairs, and after-sales service personnel handling the issues on-site based on the reported problems. Summary of the Invention

[0003] The inventors noted the following drawbacks in the after-sales service of the aforementioned equipment.

[0004] 1. The first method described above uses manual inspection, which requires after-sales service personnel to visit the after-sales site regularly, increasing the demand for human resources and maintenance costs. In addition, for fixed inspection items, after-sales service personnel make subjective judgments, which can easily lead to misjudgments.

[0005] 2. The second method described above relies on customer-initiated repair requests. In this case, the equipment has often already malfunctioned, and after-sales personnel are in a reactive state. Furthermore, when facing complex problems, the lack of troubleshooting tools often necessitates coordination with R&D personnel for location analysis, making it difficult to resolve issues efficiently and quickly. This results in prolonged on-site service interruptions. There is also a lack of records and summaries for each repair, hindering the formation of a knowledge base and providing experience for future problem-solving. Additionally, the lack of service evaluation methods makes it impossible to assess the service quality of after-sales personnel and prevent them from continuously developing a strong after-sales service mindset.

[0006] The above two methods, which rely on manual periodic inspections and passive responses to handle on-site equipment problems, make it difficult to establish a high-quality after-sales service system, and fail to provide early warnings and rapid post-incident location, thus hindering the improvement of efficiency in after-sales equipment handling.

[0007] Accordingly, this disclosure provides a device operation and maintenance method that analyzes the real-time operating data of the target device to determine whether the target device has a fault, thereby enabling convenient and quick fault repair of the target device and effectively improving the operation and maintenance efficiency of the target device.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] Figure 1 This is a flowchart illustrating a device operation and maintenance method according to an embodiment of the present disclosure. In some embodiments, the following device operation and maintenance method is executed by a device operation and maintenance device, including steps 11-14.

[0037] In step 11, real-time operating data of the target device is obtained.

[0038] In some embodiments, the target device includes devices that perform specific functions, such as CT (Computed Tomography) security screening equipment.

[0039] In step 12, the operating data is analyzed to determine if the target device is faulty.

[0040] In some embodiments, a fault identification model is used to process operational data in order to obtain fault type information of the target device when a fault of a specified fault type exists in the target device, wherein the fault identification model is a model obtained by training a machine learning model on fault identification.

[0041] For example, a fault identification model can be obtained by training a machine learning model using at least one of the following algorithms: logistic regression, naive Bayes, nearest neighbor, decision tree, and support vector machine.

[0042] In step 13, if it is determined that the target device has a fault of a specified fault type, the location information of the target device is queried using the after-sales records.

[0043] In step 14, a fault warning message is sent to the after-sales service terminal. The fault warning message includes the device identifier of the target device, the location information of the target device, and the fault type information of the target device, so that the staff can perform fault repair on the target device according to the fault warning message presented by the after-sales service terminal.

[0044] It should be noted that, based on the fault warning information displayed on the after-sales service terminal, staff can understand the location of the target device, the device information, and the type of fault, so that staff can promptly repair the target device.

[0045] In the equipment operation and maintenance method provided in the above embodiments of this disclosure, by analyzing the real-time operating data of the target equipment to determine whether the target equipment has a fault, the target equipment can be repaired conveniently and quickly, thereby effectively improving the operation and maintenance efficiency of the target equipment.

[0046] Figure 2 This is a schematic flowchart of a device operation and maintenance method according to an embodiment of the present disclosure. In some embodiments, the following device operation and maintenance method is executed by a device operation and maintenance device, including steps 21-27.

[0047] In step 21, real-time operating data of the target device is obtained.

[0048] In some embodiments, the target device includes devices that perform specific functions, such as CT scanners.

[0049] In step 22, the operating data is analyzed to determine if there is a fault in the target device.

[0050] In some embodiments, a fault identification model is used to process operational data in order to obtain fault type information of the target device when a fault of a specified fault type exists in the target device, wherein the fault identification model is a model obtained by training a machine learning model on fault identification.

[0051] For example, a fault identification model can be obtained by training a machine learning model using at least one of the following algorithms: logistic regression, naive Bayes, nearest neighbor, decision tree, and support vector machine.

[0052] In step 23, if it is determined that the target device has a fault of a specified fault type, the operation and maintenance plan for the target device is determined based on the fault type information of the target device.

[0053] In some embodiments, the step of determining the operation and maintenance plan for the target device based on the fault type information of the target device includes steps S11-S12.

[0054] S11. Determine the fault analysis report based on the fault type information.

[0055] It should be noted that the fault analysis report includes the specific details of the fault, the candidate causes of the fault, and the scope of the fault's impact.

[0056] S12. Based on the fault analysis report and the pre-configured maintenance knowledge graph, determine the operation and maintenance plan for the target equipment.

[0057] In some embodiments, the fault analysis report is used as a query condition. Based on parameters such as the specific type of fault, possible causes, and scope of impact, a pre-configured maintenance knowledge graph is used to retrieve maintenance solutions that match the target fault analysis report. Since multiple maintenance solutions may match the target fault analysis report, the retrieved solutions can be filtered and sorted, for example, by information such as applicability, feasibility, and historical success rate. Finally, a superior maintenance solution or a solution selected by the user is determined.

[0058] In step 24, the location information of the target device is retrieved using the after-sales records.

[0059] In step 25, a fault warning message is sent to the after-sales service terminal. The fault warning message includes the target device's device identifier, the target device's location information, the target device's fault type information, and the target device's operation and maintenance plan. This allows staff to perform efficient fault repair on the target device based on the fault warning message presented by the after-sales service terminal and the presented operation and maintenance plan.

[0060] It should be noted that, based on the fault warning information displayed on the after-sales service terminal, staff can understand the location of the target device, the device information, the type of fault, and the maintenance plan, enabling them to perform efficient fault repair on the target device.

[0061] In step 26, a maintenance report entered by staff is received from the after-sales service terminal.

[0062] In step 27, the maintenance knowledge graph is updated using the maintenance report.

[0063] It's important to note that based on the fault warnings displayed on the after-sales service terminal, staff perform fault repairs on the target equipment. After completing the repairs, they submit a corresponding maintenance report to the equipment maintenance unit. This report includes the specific type of fault, its manifestation, cause analysis, scope of impact, and the maintenance solution ultimately adopted to overcome the fault. The equipment maintenance unit uses this report to update its maintenance knowledge graph, enabling it to provide more accurate maintenance solutions in the future.

[0064] In addition, based on the maintenance reports entered by staff, fault handling information can be effectively traced to further improve the quality of after-sales service.

[0065] In some embodiments, after-sales records are used to query the associated users of the target device and send fault warning information to the user terminals of the associated users so that the user terminals can present the fault warning information to the associated users.

[0066] Through the above processing, the associated users of the target device can be informed in a timely manner that the target device is currently malfunctioning, so as to effectively avoid the security risks caused by the associated users continuing to use the malfunctioning target device.

[0067] In some embodiments, upon receiving a query request from a user terminal, the query request is processed using a trained large language model to obtain a response content corresponding to the fault type information of the target device, wherein the query request includes the fault type information of the target device. Based on this, the response content is sent to the user terminal.

[0068] It should be noted that after seeing the fault warning message displayed on the user's terminal, the associated user may want to know more information related to the fault. In this case, using a trained large language model to answer the related questions raised by the associated user can provide the associated user with more information related to the fault, thereby effectively improving the after-sales service experience.

[0069] In addition, associated users can provide service evaluation information to the equipment maintenance unit through their user terminals, so as to further improve the quality of authorized services based on the service evaluation information provided by associated users.
