[0025] It should be noted that Figure 1 The scenario diagram of the intelligent management system for the entire life cycle of electric power materials shown is merely an example. The intelligent management system for the entire life cycle of electric power materials and the scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the intelligent management system for the entire life cycle of electric power materials and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is equally applicable to similar technical problems.

[0026] First, an embodiment of the present application provides an intelligent management method for the entire life cycle of electric power materials, which includes: the front-end layer obtains an access request from a user node and sends it to a gateway layer, and displays a response result corresponding to the access request returned by the gateway layer to the user node, and the access request is used to process the electric power material life cycle management information generated in the process of the electric power material life cycle management, and the electric power material life cycle management information includes basic material information, material procurement records, material inventory changes, and material usage information; the gateway layer sends the access request to the back-end service corresponding to the request type based on the request type of the access request, and returns the response result of the back-end service to the front-end layer, wherein different request types correspond to different back-end services; the back-end service of the application layer processes the access request and determines the response result from the data layer, and returns the response result to the gateway layer; the data layer stores the electric power material life cycle management information generated in the process of the electric power material life cycle management and updates the electric power material life cycle management information based on the access request.

[0027] like Figure 2 As shown, Figure 2 1 is a flow chart of an embodiment of the method for intelligent management of the entire life cycle of electric power materials provided in the embodiments of the present application. The method for intelligent management of the entire life cycle of electric power materials includes the following steps:

[0028] 201. The front-end layer obtains the access request of the user node and sends it to the gateway layer, and displays the response result corresponding to the access request returned by the gateway layer to the user node.

[0029] The front-end layer is mainly responsible for interacting directly with users, displaying system functions and processing user input, ensuring that users can easily access and operate the system, while optimizing the experience and functions through platform features.

[0030] The front-end layer provides an intuitive interface to display system functions and content. The web page is presented through a browser, the APP is presented through the application interface of the mobile device, and the mini program is embedded in the ecosystem of a specific platform. The front-end layer displays data obtained from the back-end, such as lists, charts, etc., and processes user input, such as form submissions and search requests. These functions can be implemented on the web, APP, and mini program sides, but the form and optimization methods may be different. The front-end layer verifies the user's operations in real time and provides instant feedback to ensure the correctness of the user's input and improve the smoothness of the operation.

[0031] In an embodiment of the present application, the intelligent management method for the entire life cycle of electric power materials is applied to the intelligent management system for the entire life cycle of electric power materials. The intelligent management system for the entire life cycle of electric power materials includes a front-end layer, a gateway layer, an application layer and a data layer, and the application layer includes multiple back-end services.

[0032] Among them, the access request is used to process the power material life cycle management information generated during the power material life cycle management process. The power material life cycle management information includes basic material information, material procurement records, material inventory changes and material usage information.

[0033] The access request can be a query request or a write request. For example, the user node initiates the writing of its own private power material life cycle management information to the front-end layer. For example, its own private power material life cycle management information can include the basic information of the material on that day, the material procurement record, the material inventory change and the material usage information. The basic information of the material includes the name and location of the material, etc. The material procurement record includes the record of the material procurement. The material inventory change includes the inventory change of each power equipment. The material usage information includes the operating parameters of each power equipment.

[0034] In the embodiment of the present application, the front-end layer can display the response result on the display of the user node. The user node can be a PC terminal, a mobile terminal, a third-party application or a management backend, etc. The user can operate on the front-end page of the user node and input the access request to the front-end layer through the user node.

[0035] 202. The gateway layer sends the access request to the backend service corresponding to the request type based on the request type of the access request, and returns the response result of the backend service to the front-end layer.

[0036] The gateway layer is mainly responsible for request routing, load balancing, and security control. It forwards front-end requests to appropriate back-end services, implements authentication and authorization, and optimizes system performance and reliability. By processing data format conversion and cache management, the gateway layer improves the system's response speed and overall efficiency.

[0037] The gateway layer routes requests to the corresponding services or backend systems based on the type and target of the request. This typically involves parsing, forwarding, and load balancing of requests. The gateway layer distributes requests to multiple servers or instances to ensure system load balancing and improve service reliability and performance. The gateway layer is responsible for dynamically adjusting traffic distribution to optimize resource usage. The gateway layer handles authentication and authorization to ensure that only verified users or systems can access specific resources or services. This includes processing API keys, OAuth tokens, and other authentication mechanisms. The gateway layer converts request and response data into the appropriate format and supports conversion between different protocols, such as from HTTP to HTTPS or other protocols.

[0038] Among them, different request types correspond to different backend services.

[0039] like Figure 3 As shown, in the embodiment of the present application, the application layer includes multiple backend services. Specifically, the application layer may include three service types: business services, ESC basic services, and external services. The three types of backend services are used to process different request types. The access request includes three types of request types, corresponding to three different business services.

[0040] like Figure 3 As shown, business services also include user services, supplier services, supplier evaluation services, material maintenance management services, material data services, procurement cost services, maintenance cost management services, data analysis services, etc. ESC basic services include mail services, file services, ID services, SMS services, and data services, etc. External services include procurement system services, warehousing system services, and ERP system services.

[0041] like Figure 3As shown, further, the application layer also includes an ESC service monitoring module, and the ESC service monitoring module includes link tracking, fuse protection, log center and business monitoring.

[0042] like Figure 3 As shown, in the embodiment of the present application, the gateway layer can be an ESC service gateway. The gateway layer includes a routing module, a load balancing module, a safety protection device and a current limiting module.

[0043] In the embodiment of the present application, the gateway layer sends the access request to the backend service corresponding to the request type based on the request type of the access request, including:

[0044] (1) Determine whether the number of access requests currently processed by the electric power material full life cycle intelligent management system exceeds a preset number.

[0045] The preset number may be set according to specific circumstances, for example, the preset number is 10,000.

[0046] (2) If the number of requests does not exceed the preset number, the user node verification information of the access request is obtained.

[0047] In the embodiment of the present application, the user node verification information may include permission level, account name, etc.

[0048] (3) Verify whether the user node verification information meets the access permission conditions.

[0049] In an embodiment of the present application, the access permission conditions include that the permission level in the user node verification information is higher than the data security level of the data to be accessed by the access request, and the account name belongs to the white list of the data to be accessed by the access request.

[0050] (4) If the user node verification information meets the access permission conditions, the request type of the access request is obtained.

[0051] (5) Based on the request type of the access request, the access request is sent to the backend service corresponding to the request type.

[0052] In a specific embodiment, a backend service starts a service instance and sends an access request to a service instance in the backend service corresponding to the request type.

[0053] In another specific embodiment, a backend service starts multiple service instances, and based on the request type of the access request, the access request is sent to the backend service corresponding to the request type, including:

[0054] (1) Get multiple service instances of the backend service.

[0055] (2) Get the CPU usage and memory usage of each service instance.

[0056] (3) Determine the instance priority of each service instance based on the CPU usage and memory usage of each service instance, wherein the greater the CPU usage and memory usage, the lower the instance priority.

[0057] (4) The access request is load balanced to the service instance with the highest instance priority among the backend services corresponding to the request type.

[0058] 203. The backend service of the application layer processes the access request and determines the response result from the data layer, and returns the response result to the gateway layer.

[0059] In the embodiment of the present application, the data layer includes a cache database, a relational database and multiple document databases. The read and write speed of the cache database is greater than the read and write speed of the relational database, and the read and write speed of the relational database is greater than the read and write speed of the document database; the storage upper limit of the cache database is less than the storage upper limit of the relational database, and the storage upper limit of the relational database is less than the storage upper limit of the document database; the intelligent management method of the whole life cycle of electric power materials includes: when the amount of data in the cache database is greater than the first preset value, the application layer transfers part of the whole life cycle management information of electric power materials cached in the cache database to the relational database; when the amount of data in the relational database is greater than the second preset value, the application layer transfers part of the whole life cycle management information of electric power materials cached in the relational database to the document database. Among them, the first preset value and the second preset value can be set according to the specific situation.

[0060] In an embodiment of the present application, the data layer includes a cache database, a relational database and multiple document databases. The cache database is a Redis cluster, the relational database is a MySQL master-slave cluster, and the multiple document databases are a Mongo master-slave cluster, an ES cluster and a Couchbase cluster.

[0061] In the embodiment of the present application, the material usage information includes the operating parameters of each power equipment, and the intelligent management method for the entire life cycle of power materials includes:

[0062] (1) The application layer obtains the operating parameters of the target power equipment according to a preset period, and obtains a preset number of operating parameters of the preset period.

[0063] The preset period may be a preset time period, such as 30 seconds, that is, the operation is repeated every 30 seconds.

[0064] In the embodiment of the present application, the target power equipment may be a photovoltaic unit or a wind turbine unit, and the operating parameters of the target power equipment include parameters such as equipment heartbeat, equipment output power, equipment temperature, port service or business instruction execution status, etc. The operating parameters are used to identify or quantify the normality of the heartbeat, port service or business instruction execution status, etc.

[0065] (2) Inputting the operating parameters of a preset number of preset cycles into the pulse function sub-model, and obtaining the abnormal state identification corresponding to the preset number of preset cycles output by the pulse function sub-model.

[0066] The pulse function sub-model refers to a model including a pulse function, which is used to perform pulse processing on input parameters.

[0067] In the embodiment of the present application, the pulse function sub-model can be expressed by the following formula:

[0068]

[0069] Wherein, y represents the abnormal state flag output by the pulse function sub-model, y=1 represents an abnormal state, y=0 represents a normal state, and Sign() is the sign function of the pulse function. is the result of abnormal state identification corresponding to the operating parameters in the ε time period (a preset cycle). t is the time independent variable.

[0070] Among them, δ is the pulse function. Each parameter indicator corresponds to an abnormal standard value x0, and the parameter indicator corresponds to an operating parameter x. For example, when the parameter indicator is the device heartbeat, if the operating parameter x indicates that the device heartbeat link is abnormal, such as being unable to ping, then it is determined that the operating parameter x is greater than the abnormal standard value x0; when the parameter indicator is the device output power, if the operating parameter x indicates that there is a problem with the device output power, then it is determined that the operating parameter x is greater than the abnormal standard value x0; when the parameter indicator is the business instruction situation, if the operating parameter x indicates that the business instruction is not executed, then it is determined that the operating parameter x is greater than the abnormal standard value x0.

[0071] (3) Inputting abnormal status identifiers corresponding to a preset number of preset cycles into an accumulation model to obtain a fault detection result output by the accumulation model, where the accumulation model refers to a model used to accumulate input data.

[0072] The cumulative model refers to a model used to accumulate input data.

[0073] In the embodiment of the present application, the cumulative model can be expressed by the following formula:

[0074]

[0075] Among them, H n(t) represents the abnormal detection result. If H n (t) = 1, indicating that the abnormal detection result is a fault type; if H n (t) = 0, indicating that the abnormal detection result is a normal type; y0 represents the threshold of the number of times the abnormal state is marked as 1, that is, y0 represents the abnormal number threshold of the number of times the abnormal state is marked as an abnormal state, and y0 can be set according to specific circumstances. n represents the number of preset cycles.

[0076] In a specific embodiment, historical operation information of the target power equipment is obtained, wherein the historical operation information includes the statistical number of times that the abnormal state of the target power equipment within a preset period before the failure occurred is marked as an abnormal state, and the average number of statistical times counted when multiple failures occurred is determined as the abnormal number threshold.

[0077] (4) When the fault detection result is a fault type, the target power equipment is recorded as faulty once; when the fault detection result is a normal type, the target power equipment is recorded as normal once.

[0078] (5) The proportion of fault detection results of the fault type within a preset time period is determined as the failure rate.

[0079] In the embodiment of the present application, the preset time period can be 1 day, two days, etc., which can be set according to the specific situation.

[0080] For example, if the number of fault detection results of the fault type in the preset time period accounts for 20%, then the fault rate is determined to be 20%.

[0081] (6) Obtain the available time ratio of the target power equipment within a preset time period.

[0082] The available time ratio is the ratio of the available time of the target power equipment to the length of the preset time period.

[0083] (7) Determine the maintenance period of the target power equipment based on the failure rate and the proportion of available time of the target power equipment, wherein the higher the proportion of available time, the longer the maintenance period, and the higher the failure rate, the shorter the maintenance period.

[0084] (8) The maintenance cycle of the target power equipment is returned to the gateway layer as a response result.

[0085] 204. The data layer stores the electric power material life cycle management information generated during the electric power material life cycle management process and updates the electric power material life cycle management information based on access requests.

[0086] In a specific embodiment, the access request is a request to write the power material life cycle management information. Each back-end service of the application layer writes the power material life cycle management information to the data layer, and the data layer merges the new power material life cycle management information written by the back-end service with the old power material life cycle management information already stored locally to update the power material life cycle management information stored locally.

[0087] In another specific embodiment, each backend service processing of the application layer stores the access request and the corresponding response result in a cache database after determining the response result, and sets a destruction time, wherein the access request and the corresponding response result are deleted from the cache database when the time stored in the cache database reaches the destruction time;

[0088] When the front-end layer obtains the access request again, the front-end layer determines whether the response result corresponding to the access request is stored in the cache database;

[0089] When the front-end layer determines that the response result corresponding to the access request is stored in the cache database, the response result corresponding to the access request is returned to the front-end layer; if the front-end layer determines that the response result corresponding to the access request is not stored in the cache database, the access request is sent to the back-end service corresponding to the request type based on the request type of the access request, and the response result of the back-end service is returned to the front-end layer;

[0090] The front-end layer displays the response results corresponding to the access request.

[0091] Furthermore, when multiple user nodes share their own power material life cycle management information, their own power material life cycle management information may be leaked. To avoid this situation, in a specific embodiment, the power material life cycle intelligent management method includes:

[0092] (1) When the gateway layer obtains an access request, it determines whether the access request is a request to write the full life cycle management information of electric power materials.

[0093] (2) If the access request is a request to write the full life cycle management information of the electric power material, multiple sharing participating nodes participating in sharing the data are determined, and the multiple sharing participating nodes are used to receive the access request input by the user and interact with the front-end layer.

[0094] Specifically, the multiple shared participating nodes may be multiple different user nodes, and different user nodes may represent different enterprises or units.

[0095] (3) A blockchain system is constructed based on multiple shared participating nodes, and the blockchain system includes multiple shared participating nodes.

[0096] (4) Based on the node location information of each shared participating node in the blockchain system, each shared participating node is clustered to obtain three node clustering clusters.

[0097] Among them, the node location information can share the longitude and latitude of the participating nodes.

[0098] In the embodiment of the present application, each shared participating node is clustered based on the node location information of each shared participating node in the blockchain system to obtain three node clustering clusters, including:

[0099] The node location information of N shared participating nodes in the blockchain system is randomly divided into K location information sets, wherein each location information set contains N / K node location information. The K location information sets are clustered respectively to obtain three second location information clusters in each location information set. Specifically, three nodes with three node location information are randomly obtained from the location information set as three cluster center nodes, and a corresponding cluster node set is established for each cluster center node. The node similarity of two nodes corresponding to any two node location information in the location information set is calculated respectively. Specifically, the node feature information of the two nodes is converted into a feature vector and the cosine similarity is calculated to obtain the node similarity of any two nodes in the location information set. The node corresponding to each node location information in the location information set is determined as the node to be allocated, and the three node similarities between the node to be allocated and the three cluster center nodes are obtained. The node to be allocated is placed in the cluster node set corresponding to the cluster center node corresponding to the largest node similarity among the three node similarities, and three cluster node sets are obtained. Calculate the average value of the node feature information of the cluster node set, obtain the cluster node centroid of the cluster node set, and obtain 3 cluster node centroids. Calculate the deviation parameter between the 3 cluster node centroids and the 3 cluster center nodes. Specifically, calculate the node similarity between the cluster node centroid and each cluster center node, determine the cluster center node with the largest node similarity with the cluster node centroid as the neighborhood node of the cluster node centroid, and determine the difference between the cluster node centroid and the neighborhood node based on the node similarity between the cluster node centroid and the corresponding neighborhood node, wherein the greater the node similarity between the cluster node centroid and the neighborhood node, the smaller the difference between the cluster node centroid and the neighborhood node, and determine the sum of the differences corresponding to the centroids of each cluster node as the deviation parameter. When the deviation parameter is greater than the preset parameter value, update the 3 cluster node centroids to new 3 node cluster center nodes, and obtain new 3 cluster node sets and new deviation parameters corresponding to the new 3 node cluster center nodes. When the new deviation parameter is not greater than the preset parameter value, the new three clustering node sets are determined as three second location information clusters.
