[0055] Figure 2 The flowchart of the maintenance strategy generation method provided by an embodiment. This embodiment relates to the specific implementation process of a computer device generating a maintenance strategy for an engineering machinery device based on the operation data of the engineering machinery device and the maintenance cycle data of the engineering machinery device. Figure 2 As shown, the method may include:

[0056] S201, obtaining operation data of construction machinery equipment and full-cycle maintenance data of construction machinery equipment.

[0057] Specifically, the computer device obtains the operation data of the engineering machinery equipment and the maintenance cycle data of the engineering machinery equipment. Among them, the engineering machinery equipment refers to the mechanical equipment used in the process of large-scale infrastructure construction, such as loaders, cranes, installers and graders. Optionally, the operation data of the engineering machinery equipment can be the average monthly workload, average monthly startup time, average daily startup times, etc. of the engineering machinery equipment. Optionally, the maintenance cycle data of the engineering machinery equipment can be the monthly repair times, monthly maintenance times, major component replacement times, etc. of the engineering machinery equipment. Optionally, the computer device can obtain the operation data of the engineering machinery equipment through the smart IoT box. Optionally, the computer device can obtain the maintenance cycle data of the engineering machinery equipment through the enterprise resource planning (Enterprise Resource Planning, ERP), customer relationship management system (Customer Relationship Management, CRM) self-built information system. Optionally, the computer device can obtain the operation data of the engineering machinery equipment and the maintenance cycle data of the engineering machinery equipment at preset time intervals. For example, the operation data of the engineering machinery equipment and the maintenance cycle data of the engineering machinery equipment can be collected every 10 minutes. Optionally, the computer device can perform aggregation processing, slicing processing or block processing on the operation data of the engineering machinery equipment and the maintenance cycle data of the engineering machinery equipment. Aggregation processing refers to generating a single value for the operation data or the maintenance cycle data, that is, generating a single value for the same type of data in the operation data or generating a single value for the same type of data in the maintenance cycle data; slicing processing and block processing on the operation data or the maintenance cycle data of the engineering machinery equipment means that the amount of the operation data or the maintenance cycle data of the engineering machinery equipment obtained is large, and the computer device only needs to obtain part of the data, then the computer device can select values ​​on a part of the preset dimensions, and determine the distribution of the operation data or the maintenance cycle data obtained on the remaining dimensions. If the distribution of the operation data or the maintenance cycle data on the remaining dimensions is two-dimensional, the operation data or the maintenance cycle data is sliced ​​to obtain the required part of the data; if the distribution of the operation data or the maintenance cycle data on the remaining dimensions is three-dimensional or more, the operation data or the maintenance cycle data is block processed to obtain the required part of the data.

[0058] S202, inputting the operation data into a first decision tree model to obtain a maintenance analysis result based on the operation data; the first decision tree model is a decision tree model established based on the operation data.

[0059] Specifically, the computer device inputs the operation data of the above-mentioned engineering machinery equipment into a decision tree model established based on the operation data of the engineering machinery equipment, and obtains a maintenance analysis result based on the above-mentioned operation data. Optionally, the maintenance analysis result based on the operation data includes a maintenance extension service or a non-extension service based on the operation data. For example, the computer device inputs the monthly average workload in the operation data of the engineering machinery equipment into the first decision tree model. If the monthly average workload is greater than the preset monthly average workload threshold, the maintenance analysis result based on the above-mentioned operation data is determined to be a maintenance non-extended service. If the monthly average workload is less than the preset monthly average workload threshold, the maintenance analysis result based on the above-mentioned operation data is determined to be a maintenance extension service. Exemplarily, the monthly average workload in the operation data of the obtained engineering machinery equipment is 150 hours, the preset monthly average workload threshold is 120 hours, and the monthly average workload is greater than the preset monthly average workload threshold, then the maintenance analysis result based on the monthly average workload of 150 hours is determined to be a maintenance non-extended service.

[0060] S203, inputting the full maintenance cycle data into a second decision tree model to obtain a maintenance analysis result based on the full maintenance cycle data; the second decision tree model is a decision tree model established based on the full maintenance cycle data.

[0061] Specifically, the computer device inputs the maintenance cycle data of the above-mentioned engineering machinery equipment into the second decision tree model to obtain the maintenance analysis result based on the above-mentioned maintenance cycle data. Optionally, the maintenance analysis result based on the maintenance cycle data includes maintenance extension service or non-extension service based on the maintenance cycle data. For example, the computer device inputs the monthly repair number in the maintenance cycle data of the engineering machinery equipment into the second decision tree model. If the monthly repair number is greater than the preset monthly repair number threshold, the maintenance analysis result based on the above-mentioned maintenance cycle data is determined to be maintenance non-extended service. If the monthly repair number is less than the preset monthly repair number threshold, the maintenance analysis result based on the above-mentioned maintenance cycle data is determined to be maintenance extended service. Exemplarily, the monthly repair number in the obtained maintenance cycle data of the engineering machinery equipment is 8 times, the preset monthly repair number threshold is 4 times, and the monthly repair number is greater than the preset monthly repair number threshold, then the maintenance analysis result based on the monthly repair number of 4 times is determined to be maintenance non-extended service.

[0062] S204: Generate a maintenance strategy for the construction machinery equipment according to the maintenance analysis results based on the operation data and the maintenance analysis results based on the maintenance cycle data.

[0063] Specifically, the computer device generates a maintenance strategy for the construction machinery equipment according to the above-mentioned maintenance analysis results based on the operation data and the maintenance analysis results based on the maintenance cycle data. Optionally, the maintenance analysis results based on the operation data can be a maintenance extension service or a maintenance non-extension service, and the maintenance analysis results based on the maintenance cycle data can be a maintenance extension service or a maintenance non-extension service. The computer device can generate a maintenance strategy for the construction machinery equipment according to the analysis results of the two, that is, the generated maintenance strategy for the construction machinery equipment can be a maintenance extension service or a maintenance non-extension service.

[0064] In this embodiment, the computer device first obtains the operating data of the engineering machinery equipment and the full maintenance cycle data of the engineering machinery equipment, inputs the operating data into the first decision tree model, and obtains the maintenance analysis results based on the operating data, and inputs the full maintenance cycle data into the second decision tree model, and obtains the maintenance analysis results based on the full maintenance cycle data. According to the maintenance analysis results based on the operating data and the maintenance analysis results based on the full maintenance cycle data, a maintenance strategy for the engineering machinery equipment can be generated, and the maintenance strategy of the engineering machinery equipment can be updated in time according to the operating data of the engineering machinery equipment and the full maintenance cycle data of the engineering machinery equipment, which solves the problem of untimely updating of the maintenance strategy of the engineering machinery equipment in traditional technologies.

[0065] Figure 3 A schematic diagram of a maintenance strategy generation method provided in an embodiment. This embodiment relates to a specific implementation process of generating a maintenance strategy for construction machinery equipment by a computer device based on the maintenance analysis results of operation data and the maintenance analysis results based on the maintenance cycle data. Figure 3 As shown, on the basis of the above embodiment, as an optional implementation mode, the above S204 includes: if the maintenance analysis result based on the operating data is the maintenance extension service based on the operating data, and the maintenance analysis result based on the full maintenance cycle data is the maintenance extension service based on the full maintenance cycle data, then the maintenance strategy of the construction machinery equipment is determined to be the implementation of the extended maintenance strategy; if the maintenance analysis result based on the operating data is the maintenance non-extended service based on the operating data, and the maintenance analysis result based on the full maintenance cycle data is the maintenance non-extended service based on the full maintenance cycle data, then the maintenance strategy of the construction machinery equipment is determined to be not to implement the maintenance extension strategy.

[0066] Specifically, if the maintenance analysis result based on the above operation data of the computer equipment is a maintenance extension service based on the operation data, and the maintenance analysis result based on the above maintenance cycle data is a maintenance extension service based on the maintenance cycle data, then Figure 3 As shown, the computer equipment determines that the maintenance strategy of the engineering machinery equipment is to implement the extended maintenance strategy, that is, Figure 3As shown in area A; if the maintenance analysis result based on the above operation data of the computer equipment is that the maintenance service based on the operation data is not extended, and the maintenance analysis result based on the above maintenance cycle data is that the maintenance service based on the maintenance cycle data is not extended, then Figure 3 As shown, the computer equipment determines that the maintenance strategy of the engineering machinery equipment is to implement the non-extended maintenance strategy, that is, Figure 3 Optionally, if the computer device obtains any one of the maintenance analysis results based on the above operation data and the maintenance analysis results based on the above maintenance cycle data, that is, the maintenance service will not be extended, then the computer device prompts to determine the maintenance strategy of the construction machinery equipment offline, that is, Figure 3 Shown in areas B and C.

[0067] In this embodiment, after the computer equipment obtains the maintenance analysis results of the engineering machinery equipment based on the operation data and the maintenance analysis results based on the full maintenance cycle data, it can quickly determine the corresponding maintenance strategy of the engineering machinery equipment based on the results of the two, thereby improving the efficiency of determining the maintenance strategy of the engineering machinery equipment and being able to timely update the maintenance strategy of the engineering machinery equipment based on the operation data and full maintenance cycle data of the engineering machinery equipment.

[0068] Figure 4(a) is a schematic diagram of a first decision tree model provided by an embodiment; Figure 4(b) is a schematic diagram of a second decision tree model provided by an embodiment. Based on the above embodiment, as an optional implementation, as shown in Figure 4, the operation data includes at least one of the monthly average workload of the engineering machinery equipment and the monthly average startup time of the engineering machinery equipment, the average daily startup times, the startup fuel consumption change rate, the current location of the engineering machinery equipment, and the distance to the maintenance network. The full maintenance cycle data includes at least one of the monthly repair times of the engineering machinery equipment and the monthly maintenance times of the engineering machinery equipment, the number of major component replacements, and the average monthly service profit outside the warranty period.

[0069] Specifically, as shown in Figure 4(a), the above-mentioned operating data includes the average monthly workload of the engineering machinery equipment and at least one of the average monthly startup time of the engineering machinery equipment, the average daily startup times, the startup fuel consumption change rate, the current location of the engineering machinery equipment, and the distance to the maintenance point. Exemplarily, the computer device first inputs the monthly average workload of the engineering machinery equipment into the first decision tree model to obtain an analysis result. If the input monthly average workload of the engineering machinery equipment is greater than the preset monthly average workload threshold, the maintenance strategy of the engineering machinery equipment is determined to be not extending the maintenance service, and the subsequent maintenance strategy determination and analysis steps are no longer performed; if the input monthly average workload of the engineering machinery equipment is less than the preset monthly average workload threshold, the maintenance strategy of the engineering machinery equipment is determined to be extending the maintenance service, and then the monthly average startup time, daily average startup times, startup fuel consumption change rate, current location of the engineering machinery equipment, and distance from the maintenance point of the engineering machinery equipment are used to further determine the maintenance strategy of the engineering machinery equipment. It can be understood that if any parameter of the monthly average startup time, daily average startup times, startup fuel consumption change rate, current location of the engineering machinery equipment, and distance from the maintenance point of the engineering machinery equipment is input into the first decision tree model, the result obtained is that the maintenance service is not extended, then the subsequent parameters will no longer be used to determine and analyze the maintenance strategy of the engineering machinery equipment.

[0070] As shown in FIG4(b), the above-mentioned maintenance cycle data includes at least one of the monthly repair times of the engineering machinery equipment and the monthly maintenance times of the engineering machinery equipment, the major component replacement times, and the monthly average service profit outside the warranty. Exemplarily, the computer device first inputs the monthly maintenance times of the engineering machinery equipment into the second decision tree model to obtain the analysis result. If the monthly maintenance times of the input engineering machinery equipment are greater than the preset monthly maintenance times threshold, the maintenance strategy of the engineering machinery equipment is determined to be not to extend the maintenance service, and the subsequent maintenance strategy determination and analysis steps are no longer performed; if the monthly maintenance times of the input engineering machinery equipment are less than the preset monthly maintenance times threshold, the maintenance strategy of the engineering machinery equipment is determined to be extended maintenance service, and the major component replacement times of the engineering machinery equipment and the monthly average service outside the warranty are further used to determine the maintenance strategy of the engineering machinery equipment. It can be understood that if the result of inputting any parameter of the major component replacement times of the engineering machinery equipment and the monthly average service outside the warranty into the second decision tree model is that the maintenance service is not extended, then the subsequent parameters will no longer be used to determine and analyze the maintenance strategy of the engineering machinery equipment.

[0071] In this embodiment, the operating data input into the first decision tree model include the average monthly workload of the engineering machinery equipment, as well as the average monthly startup time of the engineering machinery equipment, the average daily startup times, the startup fuel consumption change rate, the current location of the engineering machinery equipment, and at least one of the distances to maintenance outlets; the full maintenance cycle data input into the second decision tree model include the monthly repair times of the engineering machinery equipment, the monthly maintenance times of the engineering machinery equipment, the number of major component replacements, and the average monthly service profit outside the warranty period. When the above parameters are used to generate the maintenance strategy for the engineering machinery equipment, as long as the maintenance strategy determined by any of the parameters is not to extend the maintenance service, the subsequent parameters will no longer be used to analyze and determine the maintenance strategy for the engineering machinery equipment, thereby improving the efficiency of generating the maintenance strategy for the engineering machinery equipment; and when the maintenance strategy determined by any of the parameters is to extend the maintenance service, the subsequent parameters will continue to be used to analyze and determine the maintenance strategy for the engineering machinery equipment, thereby improving the accuracy of the generated maintenance strategy for the engineering machinery equipment.

[0072] Figure 5 This is a schematic diagram of a maintenance strategy generation method provided by another embodiment. This embodiment involves a specific implementation process of a computer device generating a maintenance strategy for an engineering machinery device. Figure 5 As shown, based on the above embodiment, as an optional implementation manner, before the above S202, the above method further includes:

[0073] S501, determining whether the construction machinery equipment is in a heavy load condition.

[0074] Specifically, the computer device can collect the load condition of the above-mentioned engineering machinery equipment through the smart IoT box to determine whether the engineering machinery equipment is in a heavy load condition. If not, execute S502; if so, execute S503. Optionally, the computer device can compare the collected load condition of the engineering machinery equipment with a preset load condition threshold to determine whether the engineering machinery equipment is in a heavy load condition. Exemplarily, the preset load condition threshold is 1200 tons. If the collected load condition of the engineering machinery equipment is 800 tons, it is determined that the engineering machinery equipment is not in a heavy load condition. If the collected load condition of the engineering machinery equipment is 1500 tons, it is determined that the engineering machinery equipment is in a heavy load condition.

[0075] S502, a step of inputting the operation data into a first decision tree model to obtain a maintenance analysis result based on the operation data is executed.

[0076] For details, please refer to the description related to this step in the above embodiment, which will not be repeated in this embodiment.

[0077] S503, determining that the maintenance strategy for the construction machinery equipment is not to implement the extended maintenance strategy.

[0078] Specifically, if the computer device determines that the above-mentioned engineering machinery equipment is in a heavy load condition, the computer device determines that the maintenance strategy of the engineering machinery equipment is not to implement the extended maintenance strategy. It can be understood that if the engineering machinery equipment is in a heavy load condition, the wear and tear of various large parts of the engineering machinery equipment is relatively serious, affecting the performance of the engineering machinery equipment, and it is not necessary to extend the maintenance.

[0079] In this embodiment, the computer device first determines the load condition of the engineering machinery equipment. If it is a heavy load condition, the maintenance strategy of the engineering machinery equipment is determined to not implement the extended maintenance strategy. If it is not a heavy load condition, the operation data is input into the first decision tree model to obtain a maintenance analysis result based on the operation data. When the engineering machinery equipment is in a heavy load condition, there is no need for subsequent analysis and determination, which further improves the efficiency of determining the maintenance strategy of the engineering machinery equipment.

This embodiment involves a specific implementation process of a computer device generating a maintenance strategy for an engineering machinery device. Figure 6 As shown, based on the above embodiment, as an optional implementation manner, before the above S203, the above method further includes:

[0081] S601, determining whether the construction machinery equipment has been maintained on time.

[0082] Specifically, the computer device can obtain the maintenance data of the engineering machinery equipment through the enterprise resource planning (ERP) and customer relationship management system (CRM) information system built by the enterprise to determine whether the engineering machinery equipment has been maintained on time. If so, execute S602; if not, execute S603. Optionally, the computer device can compare the obtained maintenance data with the expected maintenance data of the engineering machinery equipment to determine whether the engineering machinery equipment has been maintained on time. Exemplarily, the expected maintenance data of the engineering machinery equipment should be 10 times. If the maintenance data of the engineering machinery equipment obtained is 10 times, it is determined that the engineering machinery equipment has been maintained on time. If the maintenance data of the engineering machinery equipment obtained is 8 times, it is determined that the engineering machinery equipment has not been maintained on time.

[0083] S602, a step is performed in which the full maintenance cycle data is input into a second decision tree model to obtain a maintenance analysis result based on the full maintenance cycle data.

[0084] For details, please refer to the description related to this step in the above embodiment, which will not be repeated in this embodiment.

[0085] S603, determining that the maintenance strategy for the construction machinery equipment is not to implement the extended maintenance strategy.

[0086] Specifically, if the computer device determines that the above-mentioned engineering machinery equipment has not been maintained on time, the computer device determines that the maintenance strategy of the engineering machinery equipment is not to implement the extended maintenance strategy. It is understandable that if the engineering machinery equipment is not maintained on time and the major parts of the engineering machinery equipment are not regularly maintained, the performance of the engineering machinery equipment will be affected, and there is no need to extend the maintenance.

[0087] In this embodiment, the computer device first determines whether the construction machinery equipment has been maintained on time. If it has not been maintained on time, the maintenance strategy of the construction machinery equipment is determined to be not to implement the extended maintenance strategy. If it has been maintained on time, the step of inputting the full maintenance cycle data into the second decision tree model is executed to obtain the maintenance analysis results based on the full maintenance cycle data. When the construction machinery equipment has not been maintained on time, there is no need for subsequent analysis and determination, which further improves the efficiency of determining the maintenance strategy of the construction machinery equipment.

[0088] It should be understood that although Figure 2-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-6 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
