Embodiment 1:

[0027] This embodiment provides an operation and maintenance method based on an operation and maintenance work order.

[0028] See also Figure 1 , the figure shows that the method includes step S100, step S200, step S300, and step S400.

[0029] Step S100: obtaining the current equipment fault text and the maintenance personnel's historical maintenance report, wherein the equipment fault text includes the equipment type and the fault cause, and the historical maintenance report includes the maintenance personnel information and the historical equipment fault text processed by the maintenance personnel.

[0030] Specifically, the maintenance personnel information includes the maintenance personnel information including the number and the name; the historical maintenance report of each maintenance personnel is an integral text, and the integral text includes all equipment maintenance history records of the corresponding maintenance personnel.

[0031] The step S100 specifically includes:

[0032] Step S101: obtaining a current equipment fault text and first information, wherein the first information includes historical maintenance reports of all maintenance personnel and working status of all maintenance personnel, wherein the working status includes maintenance working status and idle status;

[0033] Step S102: The first information is screened based on a rule-based screening algorithm and a preset first screening condition to obtain a historical maintenance report of an idle maintenance personnel, wherein the first screening condition is that the working state of the maintenance personnel is equal to the idle state. The rule-based screening algorithm can adopt any one of a rough set, a ripper, a decision tree and a boosting algorithm, by using the first screening condition as a screening rule of the rule-based screening algorithm.

[0034] Therefore, the algorithm can filter out the historical maintenance reports of idle maintenance personnel in advance, reduce the storage space occupied by the nearest neighbor index of subsequent text feature vectors, and improve the fault response speed.

[0035] Step S200: Based on text feature vector extraction and a nearest neighbor search algorithm, the historical maintenance report of the maintenance personnel is searched for the historical maintenance report that is most similar to the current equipment fault text to obtain the most similar text.

[0036] Specifically, the step S200 includes:

[0037] Step S210: pre-processing the current equipment fault text and the maintenance personnel's historical maintenance report;

[0038] Step S210 specifically includes performing the following steps on the equipment failure text and the historical maintenance report of the maintenance personnel respectively:

[0039] Step S211: character string format processing, unifying the equipment fault text and the maintenance personnel's historical maintenance report in terms of character string format;

[0040] Step S211: Use a word segmentation tool to perform word segmentation operations on the equipment failure text and the maintenance personnel's historical maintenance report.

[0041] After preprocessing, the above equipment failure texts and historical maintenance reports of maintenance personnel are represented as word sequences.

[0042] Step S220: Based on The algorithm extracts text feature vectors from the preprocessed current equipment fault text and the maintenance personnel's historical maintenance report, respectively, to obtain a current equipment fault text feature vector and a maintenance personnel's historical maintenance report text feature vector set;

[0043] Step S230: storing the text feature vector set of the maintenance personnel's historical maintenance reports into a text feature vector nearest neighbor index, wherein the text feature vector nearest neighbor index is an index constructed based on a nearest neighbor search algorithm;

[0044] Step S240: inputting the current equipment fault text feature vector into the text feature vector nearest neighbor index to obtain the most similar text.

[0045] Step S300: extracting the corresponding maintenance personnel information from the most similar text, and generating a custom form according to the current equipment fault text and the corresponding maintenance personnel information.

[0046] The step S200 specifically includes:

[0047] The historical maintenance reports of all maintenance personnel in the idle state are screened based on the rule-based screening algorithm and the preset second screening condition to obtain the historical maintenance reports of the current equipment type, wherein the second screening condition is that the equipment type of the historical maintenance report is equal to the equipment type of the current equipment fault text;

[0048] Pre-process the current equipment fault text and the historical maintenance report of the current equipment type;

[0049] based on The algorithm extracts text feature vectors from the preprocessed current equipment fault text and the historical maintenance report of the current equipment type, respectively, to obtain a current equipment fault text feature vector and a set of text feature vectors of the historical maintenance report of the current equipment type;

[0050] The historical maintenance report text feature vector set corresponding to the equipment type of the current equipment fault text is stored in the text feature vector nearest neighbor index, wherein the text feature vector nearest neighbor index is an index constructed based on the nearest neighbor search algorithm;

[0051] The current equipment fault text feature vector is input into the text feature vector nearest neighbor index to obtain the most similar text.

[0052] The rule-based screening algorithm may adopt any one of a rough set, a ripper, a decision tree and a boosting algorithm, by using the second screening condition as a screening rule of the rule-based screening algorithm.

[0053] In this way, historical maintenance reports of the same equipment type as the current equipment fault text can be screened out first, thereby reducing the storage space occupied by the nearest neighbor index of subsequent text feature vectors and improving the fault response speed.

[0054] The text feature vector is extracted from the preprocessed current equipment fault text. Assuming that the current equipment fault text y contains k words, the current equipment fault text feature vector extraction algorithm formula includes:

[0055]

[0056] in, =

[0057] is the importance of feature word x in the current equipment fault text y, where represents the frequency of occurrence of feature word x in the current equipment fault text y, Indicates the number of occurrences of feature word x in equipment failure text y, Indicates the number of occurrences of the kth word in the equipment failure text y.

[0058] The maintenance personnel's historical maintenance report is used to extract text feature vectors. Assuming that the historical maintenance report text z contains k' words, the algorithm formula for extracting text feature vectors from the historical maintenance report includes:

[0059]

[0060] in, =

[0061] is the importance of feature word x in historical maintenance report text z, where represents the frequency of occurrence of feature word x in the historical maintenance report text z, represents the number of occurrences of feature word x in the historical maintenance report text z, Indicates the number of the historical maintenance report text z. The number of occurrences of a word, Indicates the total number of historical maintenance reports. It represents the number of historical maintenance reports containing the feature word x, where a represents the weighting coefficient, which is set according to the different positions of the feature word x in the historical maintenance report. The weighting coefficient a when the feature word x is located in the equipment type is set to 0.9-1.0, the weighting coefficient a when the feature word x is located in the fault cause is set to 0.8-0.9, and the weighting coefficient a when the feature word x is located in the fault summary is set to 0-0.2. The weighting coefficient a can be used to consider the weights of different positions of the feature word x in the historical maintenance report. The different positions of the feature word x in the historical maintenance report have different contributions to the judgment of the similarity between the historical maintenance report and the current equipment fault text. The specific weighting method can adopt the subjective weighting method.

[0062] The step S300 includes:

[0063] S310: Instantiate the visual form editor and initialize the visual form editor event, determine whether the visual form editor has an external configuration, if so, obtain the built-in configuration and the external configuration, and then create a visual form editor instance according to the merged built-in configuration and the external configuration, if not, obtain the built-in configuration, and then create a visual form editor instance according to the built-in configuration.

[0064] S320: Determine whether the visual form editor instance has an external hardware device. If so, establish communication with the external hardware device and load the external hardware device component; if not, load the Vue form element component; mount all form element components of the visual form for user configuration.

[0065] In addition to external hardware device components and Vue form element components, all form element components configured by the user in the visual form also include business customization components, which include units, personnel, and permissions. The external hardware device components may include: high-speed scanners, biometric identification devices, general devices, and special devices.

[0066] The Vue form element components include: single-line text, multi-line text, counter, map selector, radio button, multiple-choice button, drop-down selector, cascade selector, tree selector, date, time, date time, time range, time range, date time range, icon, switch, evaluation, slider, color selector, upload, rich text, group layout, subform layout and table layout.

[0067] S330: Receive the user's instruction to drag the form element component, operate the visual form content, and generate form element JSON data. The instruction includes the user's definition form element instruction based on the current equipment fault text, the corresponding maintenance personnel information and actual custom requirements, configuration form element corresponding attribute instruction, verification rule instruction and load default value instruction.

[0068] S340: Render the form element and perform a form preview according to the form element component dragged by the user, the form element JSON data, and the background interface data corresponding to the form element, and save the form data to obtain a custom form.

[0069] The S340 further includes:

[0070] S341: Determine whether an external hardware device is connected during form preview;

[0071] S342: If yes, initialize the communication connection and interaction events of the external hardware device, the external hardware device includes the high-speed scanner device, the biometric identification device, the general device and the special device, establish communication with the external hardware device, and when sending the photo taking, biometric verification or encryption instruction to the external hardware device, timely obtain the processing result of the external hardware device and display it;

[0072] S343: If not, initialize the configuration and events of the Vue form element component, and perform content format rule verification when the user enters data.

[0073] Step S400: Send the custom form to the management personnel, the custom form is used to trigger the management personnel to review and generate an operation and maintenance work order, and send the operation and maintenance work order to the corresponding maintenance personnel.

[0074] Most of the existing technologies use XML files to store form structures by dragging basic elements such as text boxes, text fields, single selections, and multiple selections, bind key nodes in the process design stage, and fill and render data through reserved variables. This method cannot flexibly expand components, especially when it comes to components that need to interact or need to obtain built-in data from the background server, and cannot meet complex form requirements. Therefore, through the above-mentioned steps of creating a custom form in the present invention, components such as file upload, three-level cascade selector, personnel pop-up window selection, data permission control, and external device access can be expanded.
