BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 A flowchart of a method for automatically distributing maintenance work orders provided in an embodiment of the present application. DETAILED DESCRIPTION

[0032] In order to make those skilled in the art better understand the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, not all. Based on the embodiments recorded in the present application, all other embodiments obtained by those skilled in the art without paying creative work are within the scope of protection of the present application.

[0033] In order to solve the problem at the production site, the embodiment of the present application provides an automatic distribution method and device for inspection and maintenance work orders. When the equipment fails, the automated process performs fault feedback, triggers the work order, automatically screens maintenance personnel, automatically distributes, and feedbacks the results. The work mode of dispatching personnel to assign and distribute is changed to the system automatic distribution mode, which greatly saves labor costs and work efficiency, and the effectiveness of result feedback. With the help of information technology, this method provides an automatic distribution method for inspection and maintenance work orders, introduces a time delay alarm algorithm, designs a key equipment fault library and a mapping table with the team ledger, and a matching algorithm for finding the "optimal" team based on the mapping table. It can automatically complete a series of operations such as alarm, triggering work orders, allocating work orders, feedback on fault elimination results, and releasing work order resources and team resources.

[0034] Based on the above content, in order to clearly and in detail illustrate the above advantages of the present application, the specific implementation methods of the present application will be described below in conjunction with the accompanying drawings.

[0035] See also Figure 1 , which is a flow chart of an automatic distribution method of maintenance work orders provided in an embodiment of the present application.

[0036] An automatic distribution method of a maintenance work order provided in an embodiment of the present application includes:

[0037] Step S101: When the target device issues a fault alarm, a corresponding work order is obtained.

[0038] In the embodiment of the present application, the work order includes: fault type, maintenance type and information of the target device.

[0039] In one example, a target device failure triggers a work order. The key parameters of the target device are collected into the information system through a real-time database. After receiving the alarm information of the device, the information system automatically generates a work application form / work commission form, i.e., a work order. As an example, the metadata of a work order includes: work ticket number, maintenance type, urgency, equipment name, equipment location number, equipment specification model, room number, equipment responsible unit, work task name, maintenance responsible team, and other information.

[0040] Step S102: Based on the work order and the dedicated fault database and team ledger of the key equipment obtained in advance, determine the responsible team from multiple maintenance teams to be selected.

[0041] Step S103: Dispatching the work order to the responsible team.

[0042] The embodiment of the present application searches for the responsible team based on the work order and the exclusive fault database and team ledger of the key equipment obtained in advance, which can reduce the human errors that may be caused by the manual distribution of work orders and improve the efficiency of work distribution; through the search process of the responsible team, things are handed over to the right person, which improves the work efficiency of the team and reduces the "empty seat" time of the team.

[0043] In some possible implementations of the embodiments of the present application, the exclusive fault library includes: attributes of key equipment, influencing factors, related information and its weight, etc.; the team ledger includes: maintenance specialty, team member qualifications, historical work order defect and fault descriptions, and areas of expertise in maintenance, etc.

[0044] As an example, a dedicated fault library is established for key equipment. The metadata in the fault library includes data such as equipment code, maintenance specialty, equipment type, defect and fault description features, personnel qualification regulations for inspection and maintenance procedures, and weights. Among them, the defect and fault description features can be obtained through word vectors preprocessed by NLP. A team ledger is established. The metadata in the ledger includes but is not limited to the following: maintenance specialty, team member qualifications, historical work order defect and fault descriptions, and areas of expertise in maintenance. The defect and fault description uses NLP to process the fault description into a series of word vectors, and then the word vectors are used to match the meaning of the words. A mapping relationship between the key equipment fault library and the team ledger is established. Assign weights. According to the importance of the metadata, weights are assigned to the dedicated fault library metadata that affects subsequent work order matching.

[0045] In one example, the weight may be set according to the importance.

[0046] In a specific example, if the matching item has an impact, E is set to 1; if the matching item has no impact, E is set to 0. Different weights can be set for different key equipment. For example, if the importance of "maintenance profession" for repairing special equipment is higher than "defects and faults", the weight W corresponding to "maintenance profession" is set higher than the weight W corresponding to "defects and faults"; if the importance of "defects and faults" for repairing general equipment is higher than "maintenance profession", the weight W corresponding to "defects and faults" is set higher than the weight W corresponding to "maintenance profession";

[0047] In some possible implementations of the embodiments of the present application, when the target device issues a fault alarm, obtaining a corresponding work order may specifically include:

[0048] When the target device issues a fault alarm, it is determined whether the fault alarm meets a preset condition; the preset condition includes n consecutive alarm variables x p Greater than the preset threshold X T ;

[0049] If yes, obtain the work order.

[0050] In the embodiment of the present application, a time delay alarm algorithm is introduced to set an alarm threshold value X for the key parameters of the target device. T , the number of alarm variables m and n. When n consecutive alarm variables x p Greater than threshold X T The system activates the alarm; when m consecutive alarm variables x p Below threshold X T The system clears the alarm. Set the alarm threshold for the target device's attention parameters. If the device's operating parameters are not within the normal range specified by the alarm threshold, the system will automatically alarm and generate a corresponding work order, which will be sent to the corresponding team for verification and troubleshooting. This greatly reduces the time for manual identification of anomalies and improves efficiency in the anomaly identification stage. The team also provides feedback on the alarm threshold during the process of verifying and eliminating anomalies. If the anomaly is found to be a false alarm, the team can provide feedback to optimize the threshold to achieve the optimal alarm.

[0051] In some possible implementations of the embodiments of the present application, step S102 may specifically include:

[0052] According to the preset weight of each matching item, a comprehensive matching score of each of the to-be-selected teams is obtained; wherein the matching item is a matching pair of the work order information and the team information;

[0053] The hosting team is determined from the teams to be selected according to the comprehensive matching score.

[0054] It should be noted that different weights can be set for different equipment. For example, if the importance of "maintenance profession" in repairing special equipment is considered to be higher than that of "defects and failures", the weight W corresponding to "maintenance profession" will be set higher than the weight W corresponding to "defects and failures"; if the importance of "defects and failures" in repairing general equipment is considered to be higher than that of "maintenance profession", the weight W corresponding to "defects and failures" will be set higher than the weight W corresponding to "maintenance profession".

[0055] In one example, the comprehensive matching score of each of the selected teams can be obtained by the matching algorithm of formula (1):

[0056] S=∑ n R＝1 W R E R (1)

[0057] In the formula, S is the comprehensive matching score, n is the number of matching items, w is the weight of different matching items, and E is the single matching score.

[0058] In specific implementation, the work unit data is not in one-to-one correspondence with the fault database metadata and the team metadata. Only keyword correspondence is sufficient. For maintenance work orders, the most important thing is to match the "optimal" team through equipment name, equipment code, maintenance specialty, and equipment defects. Other metadata information of the work order, such as urgency, room number, equipment responsible unit, etc., can be entered into the system in advance as basic data matching the equipment and automatically introduced into the work order; it can be maintained manually; it can also be left blank without affecting the entire workflow.

[0059] Taking a special equipment and a general equipment as examples, the weights of equipment type, maintenance specialty, equipment defects, and personnel qualifications are 0.2, 0.2, 0.3, and 0.3 respectively.

[0060] Special equipment: Maintenance profession and personnel qualifications are factors that must be considered. The E values ​​of equipment type, maintenance profession, equipment defects, and personnel qualifications are all 1, S = 1×0.2+1×0.3+1×0.2+1×0.3=1.

[0061] General equipment: Maintenance profession and personnel qualifications are not factors that must be considered. The E values ​​of equipment type, maintenance profession, equipment defects, and personnel qualifications are 1, 0, 1, and 0 respectively, and S = 1×0.2+0×0.3+1×0.2+0×0.3=0.4.

[0062] In one example, determining the undertaking team from the candidate teams according to the comprehensive matching score may specifically include:

[0063] In descending order of the comprehensive matching score, the working status of each of the to-be-selected teams is sequentially traversed;

[0064] The first traversed team to be selected whose working status is idle is determined as the undertaking team.

[0065] In some possible implementations of the embodiments of the present application, the determining the undertaking team from the candidate teams according to the comprehensive matching score may further include:

[0066] According to the work order and the situation of the undertaking team, determine whether it is necessary to cooperate with the team;

[0067] If so, assign the cooperating team to the hosting team.

[0068] During the specific implementation, if necessary, the cooperation with the team should be considered.

[0069] Method 1: Offline processing. The responsible team will coordinate with the other team to handle the case.

[0070] Method 2: When accessing the work order management module, the system will assist in determining whether cooperation with the team is required based on the content of the inspection and maintenance work order or the work content and requirements. When the work content requirements detect content that is inconsistent with the expertise of the team, the system will interactively remind the person in charge of the work whether it is necessary to assign cooperation work.

[0071] In one example, feedback is provided after the work order is completed. After the work order is assigned to the corresponding undertaking team, the undertaking team will verify and eliminate the fault. If the abnormality is a false alarm, the optimized threshold can be fed back to achieve the optimal alarm; if the abnormality is a correct alarm, after the undertaking team eliminates the fault, the equipment alarm is eliminated and fed back to the information system, and the information system records the current time as the completion time of the work. At the same time, the work order and team resources occupied by the undertaking team are released.

[0072] The embodiment of the present application provides an automatic distribution method for inspection and maintenance work orders, including: when the target device issues a fault alarm, obtaining the corresponding work order; the work order includes: the fault type, the maintenance type and the information of the target device; based on the work order and the pre-acquired mapping relationship between the fault and the team, determining the responsible team from multiple maintenance teams to be selected; the mapping relationship between the fault and the team is determined based on the maintenance specialty of the team; and dispatching the work order to the responsible team. The embodiment of the present application designs the mapping relationship between the fault and the team, and the matching algorithm for finding the responsible team based on the mapping relationship, which can automatically complete a series of operations such as alarm, triggering work orders, allocating work orders, feedback on fault elimination results, and releasing work order resources and team resources, greatly saving labor costs and work efficiency, and the effectiveness of result feedback.
