At the same time, the movement of the user using the mobile terminal is guided along the navigation path, and the soil layer corresponding to the underground area is calculated based on the soil moisture meter; the soil layer corresponding to the underground area is monitored based on the moisture measurement of the soil layer, thereby realizing the monitoring of the soil layer corresponding to the underground area, so that the environmental factors of the power equipment can be controlled by moisture monitoring.

[0039] S12: Taking the power equipment as the center, the soil layer corresponding to the underground area is highly stratified, and the moisture coefficient of the soil layer around the power equipment is determined;

[0040] In an embodiment of the present application, the power equipment is taken as the center, and the underground area is highly stratified based on the power equipment. At this time, the soil layer corresponding to the underground area is highly stratified, and the moisture coefficient of the soil layer around the power equipment is determined, so as to control the environment of the power equipment according to the moisture coefficient of the soil layer around the power equipment, thereby determining the actual situation of the underground environment where the power equipment is located, and thus inferring the fault prediction time of the power equipment.

[0049] In an embodiment of the present application, the moisture coefficient of the soil layer surrounding the power equipment is determined based on the moisture content of different soil layers, so as to mark the actual surrounding environment of the power equipment, so as to estimate the influence coefficient of the soil surrounding the power equipment according to the moisture coefficient of the soil layer surrounding the power equipment, thereby further limiting the influence of the soil surrounding the power equipment on the failure of the power equipment, and then triggering the drying control of the soil surrounding the power equipment based on the influence coefficient of the soil surrounding the power equipment, so as to realize the control of the surrounding soil based on the influence coefficient of the soil surrounding the power equipment, and affect the surrounding soil of the power equipment through drying control, so as to further reduce the failure of the power equipment and reduce the factors of the external environment.

[0050] S13: Constructing an environmental model of the power equipment based on the height of the soil layer and the moisture coefficient of the soil layer;

[0051] In an embodiment of the present application, an environmental model of the power equipment is constructed based on the height of the soil layer and the moisture coefficient of the soil layer, and the height of the soil layer and the moisture coefficient of the soil layer are used as two main factors of the environmental model of the power equipment, so that the environmental model of the power equipment is constructed based on these two main factors.

[0055] In an embodiment of the present application, the height of the soil layer and the moisture coefficient of the soil layer are obtained, and the height of the soil layer and the moisture coefficient of the soil layer are marked, so as to construct a surrounding environment system of the power equipment along the height of the soil layer and the power equipment, thereby reflecting the surrounding environment system of the power equipment. At this time, the surrounding environment system of the power equipment is mainly based on the surrounding environment of the power equipment, and further simulates the state of the power equipment in the underground environment according to the surrounding environment of the power equipment.

[0058] S135: sequentially adding the moisture coefficient of the soil layer to the surrounding environment system of the power equipment, and calculating the change amount of the moisture coefficient of the soil layer along the height of the soil layer;

[0059] S136: Constructing an environmental model of the power equipment according to the change in the moisture coefficient of the soil layer and the moisture coefficient corresponding to the impact position of the power equipment.

[0060] In the embodiment of the present application, the influence position of the power equipment is located according to the surrounding environment system of the power equipment, and the influence position of the power equipment is further determined, so as to process the influence position of the power equipment. At this time, the moisture coefficient of the corresponding soil layer is determined for the influence position of the power equipment, and the moisture coefficient of the soil layer is further reflected. At this time, the moisture coefficient of the soil layer is sequentially added to the surrounding environment system of the power equipment, and the change in the moisture coefficient of the soil layer is calculated along the height of the soil layer; the environmental model of the power equipment is constructed according to the change in the moisture coefficient of the soil layer and the moisture coefficient corresponding to the influence position of the power equipment, so as to use the environmental model of the power equipment to further simulate the actual situation of the circuit equipment in the underground environment.

[0061] S14: predicting the failure time of the power equipment according to the environmental model of the power equipment and the moisture resistance level of the power equipment;

[0062] In an embodiment of the present application, the failure time of the power equipment is predicted based on the environmental model of the power equipment and the moisture resistance level of the power equipment, and a preliminary estimate of the failure time of the power equipment is made to facilitate further control of the failure time of the power equipment. At this time, the environmental model of the power equipment and the moisture resistance level of the power equipment serve as the two major factors for predicting the failure time of the power equipment.

[0063] In the specific implementation process of the present invention, the specific steps may be:

[0064] S141: Obtaining an external protective layer of the power equipment;

[0065] S142: Determine the moisture resistance level of the power equipment based on the waterproof level and material of the external protective layer;

[0066] In an embodiment of the present application, the external protective layer of the electric equipment is identified in order to obtain the external protective layer of the electric equipment, and then the moisture resistance level of the electric equipment is determined based on the external protective layer of the electric equipment, so as to determine the moisture resistance level of the electric equipment based on the waterproof level and material of the external protective layer, thereby realizing the grade evaluation of the electric equipment.

[0067] S143: Environmental model of associated power equipment and moisture resistance level of power equipment;

[0068] S144: inputting the environmental model of the power equipment and the moisture resistance level of the power equipment into the failure time learning model, and predicting the failure time of the power equipment;

[0069] S145: If the fault time of the electric equipment is less than the preset fault time, further extending the fault time of the electric equipment;

[0070] In an embodiment of the present application, the environmental model of the power equipment and the moisture resistance level of the power equipment are associated, and a comprehensive evaluation is performed on the environmental model of the power equipment and the moisture resistance level of the power equipment. At this time, the environmental model of the power equipment and the moisture resistance level of the power equipment are input into a fault time learning model, and the failure time of the power equipment is predicted, so as to realize the prediction of the failure time of the power equipment. In order to further ensure the accuracy of the failure time of the power equipment, at this time, the failure time of the power equipment is compared with the preset failure time. If the failure time of the power equipment is less than the preset failure time, the failure time of the power equipment is further widened, so as to improve the accuracy of the actual time point of the failure occurrence by widening the failure time of the power equipment, thereby further avoiding the omission of the actual time point of the failure occurrence based on the widening of the failure time of the power equipment.

[0071] The method of predicting the failure time of the power equipment based on the environmental model of the power equipment and the moisture resistance level of the power equipment also includes: if the failure time of the power equipment is inconsistent with the preset failure time, further widening the failure time of the power equipment; determining the increase in the failure time of the power equipment based on the degradation of the moisture resistance level of the power equipment; determining the superimposed failure time of the power equipment based on the failure time of the power equipment and the corresponding increase, so as to ensure that the failure time of the power equipment is greater than or equal to the preset failure time. Therefore, the superposition of the failure time of the power equipment reflects the range of the failure time of the power equipment, so as to control the time point of the failure of the power equipment within the range.

[0072] S15: Determine the monitoring time of the power equipment according to the failure time of the power equipment and the water inflow of the underground area within a preset time;

[0073] In an embodiment of the present application, the failure time of the power equipment and the amount of water inflow into the underground area within a preset time further limit the monitoring time of the power equipment. In order to further control external factors, especially weather changes in the underground area within a preset time, so as to further limit the amount of water inflow into the underground area within a preset time, at this time, the monitoring time of the power equipment is determined according to the failure time of the power equipment and the amount of water inflow into the underground area within a preset time, so as to consider multiple factors in the monitoring time of the power equipment, and fully consider the weather changes in the underground area within the preset time.

[0074] In the specific implementation process of the present invention, the specific steps may be:

[0075] S151: Obtaining the failure time of the power equipment;

[0078] S154: Determine the monitoring time of the power equipment according to the failure time and the extended failure time of the power equipment.

[0079] In an embodiment of the present application, the fault time of the power equipment is obtained. At this time, the fault time of the power equipment is used as a preliminary fault time, not the actual fault time. In order to further limit the fault time, at this time, the water inflow of the underground area within a preset time is estimated based on the rain conditions corresponding to the underground area; the environmental model of the power equipment is adjusted according to the water inflow of the underground area within the preset time, and the extended fault time is determined according to the adjusted environmental model of the power equipment, so that the environmental model is adjusted according to the water inflow of the underground area within the preset time, so as to consider the weather impact in the environmental model, and the extended fault time is determined according to the adjusted environmental model of the power equipment, so as to determine the extended fault time and further superimpose the fault time. At the same time, the monitoring time of the power equipment is determined according to the fault time and the extended fault time of the power equipment.

[0080] S16: Acquiring operating parameters of the power equipment along the monitoring time of the power equipment;

[0088] In an embodiment of the present application, the monitoring time of the power equipment is obtained, the monitoring time of the power equipment is controlled, and the monitoring of the power equipment is triggered based on the monitoring time of the power equipment, and the working parameters of the power equipment are obtained in real time, so that the working parameters can be obtained in real time within the monitoring time of the power equipment, thereby forming a working parameter set, so that the working status of the power equipment can be reflected through the working parameter set.

[0089] In addition, anomaly detection is performed on the working parameters obtained by the power equipment, and a parameter set is formed for the working parameters obtained by the power equipment; data traversal is performed based on the parameter set, and multiple parameters are screened; abnormal parameters are determined based on multiple parameters, and then the abnormality of the power equipment is controlled, so that the abnormal parameters can be determined based on multiple parameters and further limited.

[0090] S17: If there are abnormal parameters in the working parameters, it is confirmed that the underground power equipment is in a fault state;

[0091] In an embodiment of the present application, the failure time of the power equipment is predicted based on the environmental model of the power equipment and the moisture resistance level of the power equipment. In order to further expand the predicted failure time, the monitoring time of the power equipment is determined based on the failure time of the power equipment and the amount of water inflow into the underground area within a preset time. At this time, the working parameters of the power equipment are obtained along the monitoring time of the power equipment; if there are abnormal parameters in the working parameters, it is confirmed that the underground power equipment is in a fault state, so as to improve the fault monitoring accuracy of the underground power equipment and realize dynamic monitoring of the underground power equipment without affecting the underground environment in which the underground power equipment is located.

[0096] S174: Confirming that the underground power equipment is in a fault state based on the current working parameters of the fault area under review.

[0097] In an embodiment of the present application, if there are abnormal parameters in the working parameters, it is predicted that the underground power equipment is in a fault state. At this time, the fault state of the underground power equipment is reflected by the abnormal parameters, and the fault factors are checked based on the fault state, and the fault area of ​​the underground power equipment is screened out to facilitate the determination of the fault area of ​​the underground power equipment, so as to review the fault area of ​​the underground power equipment and perform separate work; based on the current working parameters of the fault area during the review, it is confirmed that the underground power equipment is in a fault state.

In order to further expand the predicted failure time, the monitoring time of the power equipment is determined according to the failure time of the power equipment and the water inflow of the underground area within a preset time. At this time, the working parameters of the power equipment are obtained along the monitoring time of the power equipment; if there are abnormal parameters in the working parameters, it is confirmed that the underground power equipment is in a fault state, so as to improve the fault monitoring accuracy of the underground power equipment, and at the same time, the dynamic monitoring of the underground power equipment is realized without affecting the underground environment where the underground power equipment is located.
