The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 schematically shows an apparatus fault location method based on intelligent online real-time interaction according to an embodiment of the present invention, and as shown in fig. 1, this embodiment includes the following steps:
step S101: configuring question-answer process contents, and constructing a first database for storage, wherein the question-answer process contents comprise question contents, all possible answer options and subsequent processing modes matched with the answer contents, each question content corresponds to at least one possible answer option, and when the database is configured, one answer content corresponding to one question content and the subsequent processing mode corresponding to the specific answer content are stored as a question-answer process content record, for example, the structure shown in table 2 below. The contents of the question and answer process are designed and stored in a first database by a high-level maintenance engineer according to the diagnosis and maintenance experience of known faults. Or the design is designed and stored in the first database according to the fault diagnosis flow chart in the maintenance instruction manual of the equipment manufacturer. And describe the problem in a language as understandable to the average user as possible.
Preferably, when the content of the question answering process is configured, a judgment method and detailed operation steps are correspondingly configured for each question, and the judgment method and the operation steps are displayed while the question is presented by combining text description with a picture and a video. The detailed operation steps are all necessary operations needed for obtaining answers to questions, and the judgment method gives answers to the questions according to observation results after the operation according to the operation steps is finished. In a specific application, the judgment method comprises a manual judgment method and an automatic judgment method according to equipment data, the manual judgment method needs to be operated by a user in combination with detailed operation steps to obtain a question answer, and the automatic judgment method according to the equipment data can be used for automatically acquiring a fault log of the equipment or counting past historical data to obtain the question answer. For example, the manual judgment method may be an option that a user (such as an engineer or a device maintenance person responsible for maintenance on site) needs to measure the voltage of a location to determine the answer of the proposed question, and the corresponding detailed operation step is a specific operation step for measuring the voltage of the location, which may be displayed to the user together with a text description, a picture and a video when the question is proposed. For another example, according to a specific problem, the corresponding manual determination method may also be, for example, that the indicator light turns on green to indicate that the device is operating normally; the equipment operates normally, and no noise exists, which indicates that the equipment operates normally; the diagnosis mode of the equipment is required to be operated, the diagnosis result is totally indicated by the fact that the equipment operates normally, and the detailed operation steps corresponding to the diagnosis result can also be, for example: the equipment indicator light may need to be observed, and the equipment operation sound is heard; or a water model is used for test scanning, and then an image is obtained through observation; it is also possible to enter a device diagnostic mode, run a diagnostic program according to device prompts, and then observe the diagnostic results. For another example, the automatic determination method according to the device data is implemented as follows: for "is cold head efficiency normal? The problem content of the method can automatically acquire historical liquid helium pressure data to calculate the current cold head efficiency, and if the cold head efficiency is lower than a threshold value, an answer is automatically given: if not; for "water temperature, water flow are normal? The problem content of the method automatically acquires the current fault log and extracts water temperature and water flow data from the current fault log, and if the numerical value is in a threshold range, an answer is given: is. For the questions which can be automatically judged by the system, the answers which can be automatically judged by the system are given while the questions are asked for the user, and a brief judgment basis is given. The actual function of the first database is realized as an intelligent question-answering flow knowledge database, and a specific data structure example is shown in the following table 1:
TABLE 1
Step S102: and acquiring initial question content, and matching the initial question content with question content of the question-answering process content to acquire the matched question-answering process content from the first database. The initial problem content is fault classification, and the initial problem content is realized by receiving fault description input by a user and determining the fault classification according to the fault description. In the scenario where the user provides the fault description as the initial question content, the fault classifications selected by the user himself are all based on the initial classification of the observed phenomena, such as: the image has artifacts, the machine cannot scan, the warning light is on, and the like, the operation of directly observing the phenomena to carry out fault description and fault classification does not need equipment maintenance experience, the initial problem content can be judged and input as long as basic equipment operation and use knowledge exist, and the subsequent operation is guided by the question and answer flow content to finally determine the maintenance scheme, so that the requirements on equipment maintenance and maintenance personnel are low, the labor cost is reduced, and the efficiency is greatly improved. For example, for a fault description of a device in which a user observes that a liquid helium pressure warning lamp of a liquid helium monitor is on, the user is required to input the following fault description information:
failure time: 2019-4-199:45
And (3) fault description: the user observes that a liquid helium pressure alarm lamp of the liquid helium monitor is on.
And (4) fault classification: pressure anomaly of liquid helium
Classifying the fault into a liquid helium pressure abnormity classification according to the fault description, and selecting the fault classification by a user: and (3) the liquid helium pressure is abnormal, and the fault classification is corresponding to a fault classification identifier such as T001 (the fault classification identifier is a unique identifier of the fault classification and is used for uniquely identifying the fault classification, so that the fault classification is associated with different question answering process contents, and the detailed association relationship can be seen in an example in the table 1).
In other embodiments, the fault classification may also be determined according to the fault log content by obtaining the fault log content of the target device, specifically, a second database for storing fault classification knowledge is first constructed, specifically, a second database storage is constructed for configuring a mapping relation formation table (shown in table 2 below) of the fault code, the fault classification, and the matching mode, where the matching mode is a matching mode of an occurrence mode of the fault code and the fault classification, and includes individual matching, combination matching, and sequential combination matching. Wherein, the single matching is that when the fault code of the line appears in the fault log, the corresponding fault classification can be directly obtained, exemplarily: when a fault code A0001 appears in the equipment fault log collected in real time, the fault classification T001 can be directly obtained. The combination matching is that when all fault codes corresponding to a certain fault classification appear in the fault log, the fault classification can be determined, and the fault codes do not need to be appeared in sequence, such as: when A0002 and A0005 appear in the fault log collected in real time, the fault classification T002 can be obtained. The sequential combination matching is that when all fault codes corresponding to a certain fault classification appear in the fault log and the fault codes appear in the matching sequence, the fault classification can be determined, and exemplarily: when a0006 and a0007 occur in the fault log collected in real time and a0006 occurs before a0007 occurs, the fault classification T003 can be obtained.
TABLE 2
After analyzing the fault log content of the target equipment, the fault code can be determined, and then the mapping relation between the fault code and the second database is matched to directly obtain the fault classification, wherein the fault classification in the second database is stored by a fault classification identifier, and when the analyzed fault code is matched through the second database, the determined fault classification is represented in a fault classification identifier mode.
Whether the fault description is input by the user or the fault log automatic matching mode is adopted, after the fault classification is determined, the question and answer flow contents are automatically matched from the first database according to the fault classification so as to obtain the matched question and answer flow contents, and questions are asked for the user.
Step S103: and outputting and displaying the question content of the matched question-answering flow content to the user.
And (4) raising the questions to the user based on the obtained matched question-answer process content, preferably by outputting and displaying the question content of the matched question-answer process content to the user. Illustratively, when the obtained fault is classified as T001 (liquid helium pressure anomaly), referring to the example in table 1, the content of the question-answering flow matched from the first database is a question-answering flow corresponding to Q01, which includes the question content (corresponding to the initial question content at this time), the answer content, and the subsequent node (i.e., corresponding to the post-processing manner of the identifier), and then the processing is performed according to the post-processing manner of the identifier of the subsequent node, in this example, the subsequent node corresponds to the question-answering flow of Q02, and at this time, the question content of the question-answering flow is obtained and output to the user to start to ask the user, and the question asked is: is the helium press operating properly? At this time, the content of the judgment method and the operation step may be acquired from the content of the question-answering flow of Q02, and output and display are performed simultaneously with the question to guide the user to confirm the answer to the question according to the judgment method and the operation step, and the judgment method and the operation step are displayed by using a method of combining text description with picture and video, wherein, the specific content example of the acquired judgment method and the operation step may refer to the detailed description at step S101. Taking the question as an example, the method for determining the question corresponding to the question and answer flow content Q02 and the operation steps are simultaneously obtained and displayed, that is, while the question is presented, the operation steps are output: and checking an indicator light of the helium compressor and listening to the working sound of the helium compressor. "and" judgment method: the green light is on and a normal operating sound indicates that the helium press is operating properly. ", so that the user can guide the user to do problem troubleshooting and confirmation.
The questions which can be automatically judged by the system are asked by the user and simultaneously answers which are automatically judged by the system are given, and a brief judgment basis is given. For example, for a question that the system can automatically determine, the following question contents are output to the user:
please judge whether the water temperature and water flow are normal?
The method comprises the following operation steps: viewing water temperature, water flow data records (while giving a picture of the viewing position)
The manual judgment method comprises the following steps: exceeding the threshold value: if not; within the threshold range: is (given a threshold range at the same time)
The system automatically judges the result: and if yes, according to the latest equipment fault log record, the current water temperature is 17 ℃, and the water flow is 30L/min and is within the system threshold range.
Step S104: receiving the answer content input by the user to the question content displayed by the output.
Through the operation steps and the judgment method which are correspondingly displayed, the user can easily judge and determine the answer content corresponding to the question content and input the answer content.
Preferably, in order to facilitate the user to answer the questions, when the first database is configured, the answer content may be configured with a corresponding answer identifier, and the answer of each question may be yes or no, or may be one of multiple choices, which is represented by a uniform answer identifier, so as to uniformly manage the answers to the questions. Illustratively, as shown in table 1, the answer identifier is set as an answer ID, and the specific meaning may be: when the answer is yes or no, 0 represents no and 1 represents yes; when the answer is a plurality of choices, 0,1,2, the term, n represents each choice, Start represents that a new round of question and answer is started to check the fault after returning to the original problem content, Finish represents that the fault is solved, the maintenance treatment is finished, and Service represents that manual Service needs to be entered. Therefore, when the question content is output and displayed, the response identifier which can display the selectable answer content corresponding to the question content can be output and displayed at the same time, so that the answer content input by the user to the question content which is output and displayed is received through the selection of the user to the response identifier, the user can conveniently answer the question and perform subsequent processing according to the answer content.
Step S105: and determining a matched subsequent processing mode according to the answer content, and acquiring the subsequent processing mode to perform corresponding processing until a maintenance scheme is generated.

In a preferred embodiment, the method further includes obtaining manual service processing content, where the obtaining mode may be updating the first database according to the manual service processing content in a recording or text recording mode, and specifically may be manually entering the first database according to the manual service processing content, where the entered content is, for example, question content that needs to be further known to the customer for a certain fault phenomenon, all possible answer options, and a subsequent processing mode that matches each answer content (i.e., forming new question content or a solution step, and writing the new question content into the first database according to a data structure of the question-and-answer process content). Thereby, updating and maintaining the first database may be achieved.
In a preferred embodiment, it is also allowed that in case of finding errors or insufficient details in the question-and-answer flow during the maintenance process, the questions and operation steps in the question-and-answer flow can be modified and supplemented by the maintenance engineer, and simultaneously the modified personnel and modification time can be recorded, so as to further realize the intelligent maintenance and optimization of the first database.

As another preferred implementation, in a specific practice, when the content of the next question-and-answer flow for a certain fault description or answer option is that there are multiple questions that need to be answered in parallel, the questions may be sorted according to the length of the judgment method and the operation steps, and the questions with few operation steps and a simple judgment method are preferentially asked to the user.
