[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. At the same time, in the description of the embodiments of the present invention, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0028] The embodiments of the present invention provide a device maintenance question-answering method, a device, an electronic device, and a readable storage medium.

[0029] Specifically, this embodiment will be described from the perspective of a device maintenance question and answer device, which can be integrated into an electronic device, that is, the device maintenance question and answer method of the embodiment of the present invention can be executed by an electronic device.

[0030] The following is a detailed description in conjunction with the accompanying drawings. In this embodiment, the execution subject is an electronic device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0031] According to the background technology of the present invention, some companies provide intelligent question-and-answer platforms to answer maintenance personnel's questions about equipment parameters, maintenance, etc., so as to facilitate maintenance personnel to maintain equipment. However, simple question-and-answer methods may not provide the answers users need, mainly in that they cannot provide complete answers to equipment maintenance questions, or the answers given to equipment maintenance questions are not the answers users want, resulting in a decrease in the accuracy of responses to equipment maintenance questions.

[0032] In order to solve the above problems, the present invention discloses a device maintenance question and answer method, please refer to Figure 1 The specific process of the device maintenance question-and-answer method may be as follows: Step S10 to Step S50, wherein:

[0033] Step S10, receiving a device maintenance question input by a user, and outputting first answer information corresponding to the device maintenance question;

[0034] In this embodiment, the equipment maintenance problem is a problem that arises during the operation of the equipment and needs to be repaired, updated, or optimized. In this embodiment, an equipment maintenance question and answer interface can be provided to interact with the user to assist the user in solving equipment maintenance problems. In the equipment maintenance question and answer interface, the user can input equipment maintenance problems through voice, text, preset question selection, etc., such as "What should I do if equipment A suddenly stops working?", "What spare parts does equipment B have?", etc. After receiving the equipment maintenance problem input by the user, the equipment maintenance problem can be processed through the default model, equipment maintenance knowledge base, etc., to obtain the first answer information corresponding to the equipment maintenance problem, and the first answer information can be output based on the equipment maintenance question and answer interface. The first answer information is the initial answer given based on the equipment maintenance problem, which can assist the user in solving the equipment maintenance problem.

[0035] In some optional implementations, the equipment maintenance problem can be first classified to determine the problem type corresponding to the equipment maintenance problem. For example, for "What should I do if the robotic arm cannot start?", it can be identified that this is a maintenance problem about the robotic arm, and then it can be classified as "robotic arm failure". The frequently asked questions related to this problem type can be queried through a pre-knowledge base and output as the first answer information.

[0036] In this embodiment, upon receiving an equipment maintenance question input by a user, first equipment-related knowledge related to the equipment maintenance question can be selected from a default equipment maintenance knowledge base, where the first equipment-related knowledge is knowledge related to the equipment maintenance question. The equipment maintenance question and the first equipment-related knowledge are input into a pre-trained large language model, which can summarize information in the first equipment-related knowledge based on some keywords in the equipment maintenance question and output understandable first answer information.

[0037] The first answer information may fully meet the user's needs and be able to assist the user in solving the equipment maintenance problem that the user really wants to solve based on the equipment maintenance problem described and input by the user. However, the first answer information may not fully meet the user's needs and be unable to solve the equipment maintenance problem that the user really wants to solve.

[0038] Step S20, obtaining the user's satisfaction with the first answer information;

[0039] In this embodiment, the degree to which the first answer information can assist the user in solving the equipment maintenance problem can be represented by the user's satisfaction with the first answer information. After providing the user with a preliminary answer to his maintenance problem, that is, after outputting the first answer information, the satisfaction with the first answer information can be automatically obtained.

[0040] In some optional embodiments, after the first answer information is output, a satisfaction survey may be automatically triggered, and through the user's editing operation on the satisfaction survey, the user's evaluation information on the first answer information is obtained, thereby obtaining the user's satisfaction with the first answer information.

[0041] In one embodiment, obtaining the user's satisfaction with the first answer information may include:

[0042] Obtaining the number of related questions matching the equipment maintenance question received within a preset period of time after outputting the first answer information;

[0043] The satisfaction level is determined based on the number of related issues.

[0044] In this embodiment, the user's satisfaction with the first answer information corresponding to the maintenance question and answer information can be automatically calculated in combination with the equipment maintenance question and answer scenario without user operation. When the first answer information corresponding to the equipment maintenance question is output, all equipment maintenance questions input by the user within a preset time period including the time of outputting the equipment maintenance question are obtained, the similarity between all equipment maintenance questions and the time of the current equipment maintenance question is calculated, and the relevant equipment questions matching the current equipment maintenance question are determined from all equipment maintenance questions according to the similarity, and the number of relevant questions is counted.

[0045] It is understandable that when users do not get the answers they want, they will generally adjust the question description without changing the meaning of the words and repeatedly enter related questions. The related questions are consistent with the question and answer requirements of the current equipment maintenance problem, but repeatedly entering related questions indicates that the default equipment maintenance knowledge base has never truly solved the user's question and answer needs, and the user's satisfaction with the first answer information will not be too high. Therefore, the satisfaction can be represented based on the number of related questions in a preset time period. Setting the number of related questions as the satisfaction level can automatically determine the satisfaction of the first answer information.

[0046] In some optional embodiments, the user's satisfaction with the first answer information may be comprehensively and accurately determined based on at least one of the number of related questions and the user's evaluation information on the first answer information.

[0047] Step S30, if the satisfaction level does not exceed a preset threshold, outputting a device maintenance knowledge base selection interface;

[0048] In this embodiment, a preset threshold value for satisfaction is set in advance. If the currently detected satisfaction value does not exceed the preset threshold value, it indicates that the first answer information cannot solve the user's equipment maintenance problem, and the equipment maintenance problem needs to be remedied. Therefore, an equipment maintenance knowledge base selection interface can be output, and the equipment maintenance knowledge base interface can include a variety of knowledge bases for users to select. The knowledge base contains relevant knowledge about equipment maintenance. It can be understood that the knowledge can be in the form of text, image, video, etc.

[0049] In some optional embodiments, the device maintenance knowledge base interface may only include a device maintenance knowledge base from one source, but the device knowledge base itself has a knowledge architecture, which also includes sub-knowledge bases at different levels. Therefore, sub-knowledge bases corresponding to some levels can be selected from this device maintenance knowledge base.

[0050] In some optional embodiments, the device maintenance knowledge base interface may include device maintenance knowledge bases from at least two sources, and device maintenance knowledge bases from different sources may have different relevant knowledge about the same device, or may include different knowledge dimensions.

[0051] It is understandable that the equipment maintenance knowledge base displayed in the equipment maintenance knowledge base selection interface here may be the same knowledge base as the information in the equipment maintenance knowledge base corresponding to the first answer information.

[0052] Step S40, determining a target device maintenance knowledge base according to the selection operation received on the device maintenance knowledge base selection interface;

[0053] In this embodiment, the user can perform a selection operation on the equipment maintenance knowledge base displayed in the equipment maintenance knowledge base selection interface, and select a target equipment maintenance knowledge base that he or she prefers to be able to solve his or her equipment maintenance problem more comprehensively and accurately.

[0054] In some optional embodiments, the target device maintenance knowledge base may have at least two source device maintenance knowledge bases, and the user can select a source device maintenance knowledge base as the target device maintenance knowledge base, or select a partial sub-knowledge base from a device maintenance knowledge base as the target device maintenance knowledge base.

[0055] Step S50: re-output second answer information corresponding to the equipment maintenance question based on the target equipment maintenance knowledge base.

[0056] In this embodiment, the target device maintenance knowledge base selected by the user is more likely to contain information that solves the device maintenance problem. The user's selection of the target device maintenance knowledge base actually provides instruction information for guiding the answer to the device maintenance problem. Based on the target device maintenance knowledge base, the device maintenance problem is reprocessed, and relevant information corresponding to the device maintenance problem is selected from the target device maintenance knowledge base to obtain second answer information. Compared with the first answer information obtained based on the device maintenance problem and the default device maintenance knowledge base, the second answer information is more helpful for the user to solve the device maintenance problem, and can provide a remedial answer based on the first answer information, thereby better helping the user solve the device maintenance problem.

[0057] In the technical solution disclosed in this embodiment, a device maintenance question input by a user is received, and first answer information corresponding to the device maintenance question is output; the user's satisfaction with the first answer information is obtained; if the satisfaction does not exceed a preset threshold, a device maintenance knowledge base selection interface is output; a target device maintenance knowledge base is determined according to the selection operation received on the device maintenance knowledge base selection interface; and second answer information corresponding to the device maintenance question is re-output based on the target device maintenance knowledge base. In this way, when the user is not satisfied with the first answer information corresponding to the device maintenance question, a device maintenance knowledge base selection interface can be output, allowing the user to select the target device maintenance knowledge base they want through the device maintenance knowledge base selection interface, and the second answer information corresponding to the device maintenance question is re-output based on the target device maintenance knowledge base selected by the user, so as to remedy the last answer to the device maintenance question and assist in maintenance questions and answers, which can effectively improve the accuracy of responding to device maintenance questions.

[0058] On the other hand, this embodiment outputs the device maintenance knowledge base selection interface to provide a remedial strategy for auxiliary answers only after the first answer information is output and the satisfaction level of the first answer information is obtained to evaluate whether the user is satisfied with the first answer information. This can avoid adding unnecessary operations to the user when the user can be given an accurate answer at one time. Only when the user cannot be given an accurate answer at one time will the user be allowed to select the target device maintenance knowledge base for a remedial answer, thereby simplifying user operations and improving user experience.

[0059] In one embodiment, the device maintenance knowledge base selection interface includes Internet assistance and / or local knowledge base assistance, and determining the target device maintenance knowledge base according to the selection operation received by the device maintenance knowledge base selection interface includes:

[0060] If the device maintenance knowledge base selection interface receives a selection operation for the Internet assistance, setting the Internet as the target device maintenance knowledge base;

[0061] If the device maintenance knowledge base selection interface receives a selection operation for local knowledge base assistance, a target device maintenance knowledge base is determined based on the local knowledge base.

[0062] In this embodiment, refer to Figure 2 , the user can input the equipment maintenance question through the equipment maintenance question and answer interface, and then output the first answer information through the equipment maintenance question and answer interface. When it is determined that the user's satisfaction with the first answer information is lower than the preset threshold, the equipment maintenance knowledge base selection interface can be output in the equipment maintenance question and answer interface. The equipment maintenance knowledge base selection interface includes two strategies for assisting in answering questions: Internet assistance and local knowledge base assistance. Figure 3 After determining that the user is not satisfied with the first answer information and outputting the device maintenance knowledge base selection interface, the user can choose to click the corresponding button for Internet assistance or local knowledge base assistance in the device maintenance knowledge base selection interface according to needs to trigger the selection instruction for Internet assistance or local knowledge base assistance.

[0063] If the equipment maintenance knowledge base selection interface receives a selection operation for Internet assistance, the Internet will be set as the target equipment maintenance knowledge base, and the relevant information involved on the Internet will be used as reference information for answering equipment maintenance questions. Equipment maintenance questions can be searched on the Internet to obtain various types of information given on the Internet for equipment maintenance questions, and the second answer information can be summarized.

[0064] If the device maintenance knowledge base selection interface receives a selection operation for the local knowledge base assistance, the target device maintenance knowledge base is determined based on the local knowledge base. The local knowledge base is an internal knowledge base set up for various production lines (with several devices on the production line) or equipment, including at least one of product manuals, maintenance records, preservation ledgers, spare parts libraries, major accident reports, equipment videos and equipment drawings. There may be some non-universal knowledge in the local knowledge base. The target device maintenance knowledge base can be determined based on the local knowledge base, including using the local knowledge base as the target device knowledge base, or according to user selection, using some sub-knowledge bases in the local knowledge base as the target device maintenance knowledge base.

[0065] In this way, two remedial strategies, Internet assistance and local knowledge base assistance, are provided on the equipment maintenance knowledge base selection interface, so that a remedial second answer can be provided based on the Internet or local knowledge base, thereby assisting in solving equipment maintenance problems and improving the accuracy of responding to equipment maintenance problems.

[0066] In one embodiment, determining a target device maintenance knowledge base based on the local knowledge base includes:

[0067] Outputting the knowledge categories of the local knowledge base;

[0068] Determining a target knowledge category according to the received selection operation for the knowledge category;

[0069] The target device maintenance knowledge base corresponding to the target knowledge category is determined from the local knowledge base.

[0070] In this embodiment, a mechanism is provided to allow users to query and select the target device maintenance knowledge base by themselves. After the device maintenance knowledge base selection interface receives the selection operation for the local knowledge base assistance, the local knowledge base selection interface can be displayed on the device maintenance knowledge base selection interface. The local knowledge base has a knowledge structure. The sub-knowledge bases corresponding to each level belong to the same category. The knowledge of the devices under the knowledge bases of different categories is different. The knowledge categories of the local knowledge base are obtained and the knowledge categories of the local knowledge base are displayed in the local knowledge base selection interface. Figure 4 The user can preview the knowledge categories and determine which type of knowledge the corresponding knowledge under the knowledge category belongs to according to the knowledge category, so as to determine whether the knowledge under the knowledge category is helpful for the equipment maintenance knowledge they want to solve, and select the target knowledge category they need. According to the user's selection operation on the knowledge category received, the target knowledge category selected by the user can be determined. The knowledge contained in the target knowledge category can form a sub-knowledge base, and the sub-knowledge base can be combined into a new target equipment maintenance knowledge base. The target equipment maintenance knowledge base is selected by the user based on the category information of the local knowledge class. The knowledge therein is more targeted to equipment maintenance issues, which can further improve the accuracy of the second answer information and further improve the accuracy of responding to equipment maintenance issues.

[0071] In one embodiment, determining a target device maintenance knowledge base based on the local knowledge base includes:

[0072] Display a knowledge search box, and receive knowledge keywords input by the user through the knowledge search box;

[0073] A target device maintenance knowledge base corresponding to the knowledge keyword is selected from the local knowledge base.

[0074] In this embodiment, a mechanism can also be provided to allow the user to actively search and determine the target device maintenance knowledge base. After the device maintenance knowledge base selection interface receives a selection operation for the local knowledge base auxiliary, the local knowledge base selection interface can be displayed on the device maintenance knowledge base selection interface, and a knowledge search box can be displayed in the local knowledge base selection interface. Figure 5, users can edit the knowledge keywords corresponding to the relevant knowledge they want to find through the knowledge search box. For example, the equipment maintenance question is "Why can't the robot arm bend?" The first answer provides the user with the first answer information from the setting level, that is, the robot arm is set with parameters and cannot bend, but the user believes that this question should be answered from the fault level. Therefore, after being dissatisfied with the first answer information, the user can directly enter the knowledge keyword "robot arm failure" in the knowledge search box through the selection operation assisted by the local knowledge base. The sub-knowledge bases matching the knowledge keywords in the local knowledge base are filtered out to determine the target equipment maintenance knowledge base. At this time, the target equipment maintenance knowledge base at least contains the relevant knowledge of "robot arm failure". The target equipment maintenance knowledge base can be quickly obtained through knowledge search, saving the user's operation time and improving the user experience.

[0075] Further, refer to Figure 5 After the knowledge search box is displayed, an operation selection bar for the knowledge type can also be provided in the local knowledge base selection interface. After the user edits the knowledge search box, he can also view the sub-knowledge bases that match the knowledge keywords corresponding to different knowledge types by selecting different operation selection bars. The interface can also display the fragments that match the knowledge keywords for each sub-knowledge base for user selection.

[0076] In one embodiment, re-outputting the second answer information corresponding to the equipment maintenance question based on the target equipment maintenance knowledge base includes:

[0077] Acquire first device related knowledge corresponding to the first answer information;

[0078] In the target device maintenance knowledge base, matching the second device-related knowledge corresponding to the device maintenance problem;

[0079] Determining target device-related knowledge according to the first device-related knowledge and the second device-related knowledge;

[0080] Output second answer information corresponding to the equipment maintenance question based on the target equipment related knowledge.

[0081] In this embodiment, after determining the target device maintenance knowledge base, the target device maintenance knowledge base will contain knowledge consistent with the direction of the user to solve the maintenance problem. It is necessary to use this knowledge and combine it with the first answer information to give an answer that is different from the first answer information.

[0082] In this embodiment, during the answering process of the first answer information, after receiving the maintenance question, the first relevant knowledge matching the maintenance question is matched in the default equipment maintenance knowledge base, and then the first answer information is obtained based on the first relevant knowledge. When a second answer is required, on the one hand, it is necessary to match the second equipment-related knowledge corresponding to the equipment maintenance question in the target equipment maintenance knowledge base, and on the other hand, it is necessary to obtain the first equipment-related knowledge corresponding to the equipment maintenance question from the default equipment maintenance knowledge base when obtaining the initial answer. Based on the first equipment-related knowledge and the second equipment-related knowledge, the target equipment-related knowledge is determined. The determination method can be determined according to the user setting or according to the type of dissatisfaction corresponding to the first answer information. For example, when the first answer information is dissatisfied due to incomplete information, and the user needs a complete answer, the first equipment-related knowledge and the second equipment-related information can be merged to obtain the target equipment-related knowledge. At this time, the target equipment-related knowledge is more complete equipment-related knowledge for the equipment maintenance problem, so that a more complete second answer information can be obtained. When the first answer information is unsatisfactory because it deviates from the actual equipment maintenance problem, equipment-related knowledge that is different from the first equipment-related knowledge can be screened out from the second equipment-related knowledge as the target equipment-related knowledge, thereby filtering out irrelevant equipment-related knowledge based on the initial answer for a second answer, thereby improving the difference between the second answer information and the first answer information, and users can get more accurate answers to equipment maintenance issues.

[0083] In one embodiment, determining the target device-related knowledge according to the first device-related knowledge and the second device-related knowledge includes:

[0084] Calculating the similarity between each first sub-knowledge in the first device-related knowledge and each second sub-knowledge in the second device-related knowledge;

[0085] For each second sub-knowledge, obtaining target first device-related knowledge having the highest similarity to the second sub-knowledge;

[0086] The second sub-knowledge is sorted based on the similarity between each second sub-knowledge and the corresponding target first knowledge to determine the target device related knowledge.

[0087] In this implementation, knowledge that is not included in the first device-related knowledge can be screened out from the second device-related knowledge as the target device-related knowledge. The first device-related knowledge includes at least one first sub-knowledge, and the second device-related knowledge includes at least one second sub-knowledge. The similarity between each first sub-knowledge in the first device-related knowledge and each second sub-knowledge in the second device-related knowledge is calculated. Specifically, the similarity between the first sub-knowledge and the second sub-knowledge can be characterized by calculating the vector similarity corresponding to the first sub-knowledge and the second sub-knowledge. Given that the first device-related knowledge includes m first sub-knowledge and the second device-related knowledge includes n second sub-knowledge, m*n similarities can be calculated. For each second sub-knowledge, the similarity is calculated between it and the m first sub-knowledge, and the first sub-knowledge corresponding to the highest similarity is selected from the m similarities as the target first sub-knowledge with the highest similarity. Each second sub-knowledge is sorted according to the similarity between each second sub-knowledge and the corresponding target first knowledge. The sorting result can characterize the possibility that the second sub-knowledge exists in the first device-related knowledge similar to the first sub-knowledge, and then the most dissimilar batch of second sub-knowledge is selected to form the target device-related knowledge, so as to filter out the second sub-knowledge similar to the first sub-knowledge from the second device-related knowledge. In this way, the duplication between the second answer information and the first answer information can be reduced. When the first answer information is incomplete, the user can combine the first answer information and the second answer information to solve the equipment maintenance problem. When the first answer information deviates from the accurate answer, the useless information involved in the initial answer can be filtered out, making the second answer information more accurate, thereby further improving the accuracy of the response to the equipment maintenance problem.

[0088] In one embodiment, outputting the second answer information corresponding to the equipment maintenance question according to the target equipment related knowledge includes:

[0089] Summarizing the target device-related knowledge and outputting third answer information corresponding to the device maintenance question;

[0090] The first answer information and the third answer information are merged according to the satisfaction level to obtain the second answer information.

[0091] In this embodiment, the target device-related knowledge is the device-related knowledge that is more matched with the device maintenance problem and is selected based on the initial answer and the user's selection. The target device-related knowledge is summarized to obtain the third answer information about the device maintenance problem. In some embodiments, the third answer information can be directly output as the second answer information. In some embodiments, considering that the first answer information is also based on the device maintenance problem, it can also solve the device maintenance problem to a certain extent. Therefore, the first answer information and the third answer information can be combined to obtain the second answer information. The user's satisfaction with the first answer information is obtained. When the satisfaction is high but does not reach the preset threshold, it indicates that the user has partially affirmed the first answer information, and the first answer information contains available information for solving the device maintenance problem. Therefore, the information retention degree of the first answer information can be set to be high. When the satisfaction does not reach the preset threshold and the satisfaction is low, it indicates that the user is very dissatisfied with the first answer information, and the first answer information seriously deviates from the purpose of solving the device maintenance problem. There is less available information, so the information retention degree of the first answer information can be set to be low.

[0092] During fusion, the first answer information and the third answer information are analyzed, and the different contents between the first answer information and the third answer information are determined according to their semantic information. The different contents between the first answer information and the third answer information are retained according to the degree of information retention, and the third answer information is obtained by combining the same contents between the first answer information and the third answer information. In this way, part of the information in the first answer information is retained based on the user's satisfaction with the first answer information, and the user participates in the secondary answer process, thereby facilitating the user to solve the equipment maintenance problem based on the second answer information, and improving the effect of responding to the equipment maintenance problem.

[0093] In one embodiment, obtaining first device information in the device maintenance question and second device information in the second answer information;

[0094] Based on the first device information, filtering target device information from the second device information;

[0095] The target device information and the target device related knowledge are input into a large language model for aggregation to obtain the third answer information.

[0096] In this embodiment, the outputting of the third answer information corresponding to the equipment maintenance question based on the summary of the target equipment related knowledge includes:

[0097] Acquire the first device information in the device maintenance question and the second device information in the first answer information;

[0098] Based on the first device information, filtering target device information from the second device information;

[0099] The target device information and the target device related knowledge are input into a large language model for aggregation to obtain the third answer information.

[0100] In this embodiment, the equipment maintenance problem involves related issues on equipment maintenance, so the second answer information will also mention the relevant information of the equipment, as well as information on related equipment associated with the equipment. For example, for the maintenance problem of the palletizing robot, the maintenance problem of the conveyor belt will also be involved in the answer process. In order to answer the equipment maintenance problem more comprehensively in the second answer, the relevant equipment information such as the conveyor belt can also be used as a prompt word for the output of the third answer information.

[0101] Specifically, the first device information is extracted from the device maintenance question, and the first device information is the relevant information of the device that the device maintenance question mainly asks and answers, so that the second device information is extracted from the second answer information, and the second device information contains the information of the device that the device maintenance question mainly focuses on and its related devices, such as the device name, device type, etc. The first device information is filtered out from the second device information, and the target device information is screened out to characterize the related devices.
