Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The virtual simulation method for the power operation, provided by the embodiment of the application, can be applied to an application environment shown in fig. 1. Wherein the operation behavior sensing terminal 104 communicates through the network power operation simulation platform 102. The data storage system may be powered by data that the job simulation platform 102 needs to process. The data storage system may be integrated on the power job simulation platform 102 or may be located on a cloud or other network server. The electric power operation simulation platform 102 acquires service operation data of a service link acquired by the operation behavior perception terminal 104; inputting service operation data into a pre-constructed electric power operation simulation model, performing three-dimensional virtual operation scene exercise on service links based on the mapping relation between the service operation data and the three-dimensional virtual operation scene in the electric power operation simulation model, and determining whether the service operation data meets safety regulation constraint conditions corresponding to the service links; and if the safety regulation constraint condition is not met, carrying out early warning on the business operation of the business link according to the exercise result. The operation behavior sensing terminal 104 is a device capable of sensing operation behaviors of electric power operation field operators, such as an RFID electronic tag reader, a camera, a positioning device, various sensors, and the like. The power operation simulation platform 102 may be integrated with, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and the like.
In one embodiment, as shown in fig. 2, a virtual simulation method of an electric power operation is provided, and the method is applied to the electric power operation simulation platform 102 in fig. 1 for illustration, and includes the following steps:
step 202, acquiring service operation data of a service link acquired by a service behavior perception terminal.
The operation behavior sensing terminal is equipment capable of sensing operation behaviors of electric operation site service personnel, such as an RFID electronic tag reader, a camera, a positioning device, various sensors and the like. It can be understood that the number and the setting positions of the operation behavior sensing terminals are not limited in the application, so long as the operation behavior sensing terminals are ensured to be capable of completely collecting the operation data in the whole operation process.
The service links are obtained by dividing the electric power field service operation according to a preset service flow, and it can be understood that the preset service flow can be an execution step of an operator when executing the service operation. Specifically, the whole electric power field business operation is divided into a plurality of business links according to the execution steps when an operator executes the business operation.
The business operation data are obtained by acquiring data of the whole business operation process by the operation behavior perception terminal when an operator operates the business operation of the business link. Business operations data includes, but is not limited to, action data when a business operator performs an operation, tool data used, materials data, and environmental data throughout a business job site, etc.
Specifically, a service operator performs service operation according to service operation content to be executed in a service link, an operation behavior perception terminal in a service operation site acquires operation data corresponding to each terminal to obtain service operation data in the service link, and an electric operation simulation platform acquires the service operation data.
Step 204, inputting the business operation data into a pre-constructed electric power operation simulation model, performing three-dimensional virtual operation scene exercise on the business links based on the mapping relation between the business operation data and the three-dimensional virtual operation scene in the electric power operation simulation model, and determining whether the business operation data meets the safety regulation constraint conditions corresponding to the business links.
The electric power operation simulation model is used for performing three-dimensional virtual operation scene exercise on the business links. Specifically, a technician establishes an electric power operation simulation model in advance according to historical service operation data corresponding to a service link, and presets the electric power operation simulation model on an electric power operation simulation platform. It can be understood that, because the electric power operation simulation model is constructed based on the historical service operation data of the service link, a preset mapping relation exists between the service operation data and the three-dimensional virtual operation scene in the simulation model, and the service operation process of the whole service link can be performed with three-dimensional virtual exercise in the three-dimensional virtual operation scene according to the service operation data, so that the service operation process of the whole service link can be visually displayed.
The safety regulation constraint conditions are constraint conditions generated according to safety regulations corresponding to the service links, specifically, safety regulation constraint conditions corresponding to the service links are set in a pre-built electric power operation simulation model, when three-dimensional virtual exercise is performed on the operation process of the whole service link according to service operation data, the model can perform safety judgment on the operation process of the whole service link based on the safety regulation constraint conditions corresponding to the service links, and whether the service operation data meets the safety regulation constraint conditions corresponding to the service links is determined.
Specifically, the electric power operation simulation platform inputs the acquired service operation data into a pre-constructed electric power operation simulation model, performs three-dimensional virtual operation scene exercise on service links based on a preset mapping relation between the service operation data and the three-dimensional virtual operation scene in the electric power operation simulation model, calls safety regulation constraint conditions corresponding to the service links, and judges whether the service operation data meets the safety regulation constraint conditions corresponding to the service links.
And step 206, if the safety regulation constraint condition is not met, carrying out early warning on the business operation of the business link according to the exercise result.
Specifically, if the service operation data does not meet the safety regulation constraint condition corresponding to the service link, the potential safety hazard exists in the service operation process, and the electric power operation simulation platform performs early warning on the service operation of the service link according to the exercise result to remind service operators of paying attention to the potential safety hazard existing in the current operation.
In the virtual simulation method of the electric power operation, the service operation data of the service link is obtained, and the service operation data are acquired through the behavior perception terminal of the service site, so that the service operation data can reflect the actual operation condition of the service link, the virtual simulation exercise is carried out on the real service operation data by using the pre-built electric power operation simulation model, if the service operation data do not meet the safety regulation constraint condition, the service operation carried out on the service link is pre-warned, the service operators participating in training can know the potential safety hazard easily existing in the service link through the visualization of the exercise result of the three-dimensional virtual simulation exercise, the training effect is improved, and the risk of artificial responsibility accidents of the electric power operation site in the actual operation is further reduced.
In one embodiment, as shown in fig. 3, the process of constructing the power operation simulation model includes the steps of:
Step 302, obtaining each business link information in the power field operation information.
The power field operation information is generated after planning and integrating according to a business production plan in actual production of the power system, and divides the whole business flow according to execution steps according to the actual business production plan to obtain information of each business link. It is understood that the power field operation information specifies business operation information such as a business flow, business knowledge, and a business execution object of the power field operation. The service link information includes, but is not limited to, service link execution object information, service link operation object information, service link environment information, and the like.
Specifically, the electric power operation simulation platform acquires each business link information divided according to the steps of the business flow in the electric power field operation information.
Step 304, generating a digital service model based on the information of each service link and the safety regulation constraint conditions corresponding to each service link.
Specifically, the electric power operation simulation platform obtains safety regulation constraint conditions corresponding to each service link according to the marking information carried in each service link information, and generates a digital service model according to a preset modeling method according to the safety regulation constraint conditions corresponding to each service link information and each service link. It is understood that the digital business model may cover business links included in the entire business process.
And 306, performing association mapping on the digital business model, a behavior sensing terminal preset in the power field and a virtual character in the three-dimensional virtual scene to obtain an initial simulation model.
Wherein, the virtual roles in the three-dimensional virtual scene are correspondingly created according to the actual operation roles in the power field. It can be understood that the electric power operation simulation platform searches for a virtual role corresponding to an actual operation role in the electric power field from the virtual role database, and constructs a three-dimensional virtual scene according to the obtained virtual role.
Specifically, the electric power operation simulation platform performs association mapping on operation roles corresponding to all service links in the digital service model, a behavior sensing terminal preset on an electric power field corresponding to the operation roles and virtual roles in the three-dimensional virtual scene to obtain a triple mapping relation of a real world-digital service model-the three-dimensional virtual scene, and thus an initial simulation model is obtained. It will be appreciated that the initial simulation model is a digital twin model.
And 308, obtaining an electric power operation simulation model according to the historical service data and the initial simulation model corresponding to each service link.
The historical service data are service data generated when service operators execute service operation of the service link in a preset time period.
Specifically, the electric power operation simulation platform carries out model training on the generated initial simulation model according to the searched historical service data corresponding to each service link, and obtains the electric power operation simulation model.
In this embodiment, by constructing a digital service model including each service link, and performing association mapping on the digital service model and a behavior perception terminal in a real scene and virtual roles in a three-dimensional virtual scene respectively, an initial simulation model is obtained, and then a final electric power operation simulation model is obtained according to historical service data corresponding to each service link and the initial simulation model.
In one embodiment, generating a digital service model based on the service link information and the security procedure constraint condition corresponding to each service link includes:
Extracting link element information corresponding to each service link from each service link information according to a preset element extraction rule; and generating a digital service model based on the element information of each link and the safety regulation constraint conditions corresponding to each service link.
The link element information is element information related to service operation in the service link. It can be understood that the specific operation process of the business link can be clearly represented according to the extracted environmental element information. For example, the environmental element information may be a role in performing a business operation, a device used by the business operation, a method used by the business operation, an object of the business operation, a material used by the business operation, and the like.
The preset element extraction rule is a rule for extracting element information from service element information, specifically, the service element information is information obtained by dividing the service element information according to a service flow from electric power operation information, and because the electric power operation information comprises additional information which is not related to service operation, such as service knowledge information, in addition to necessary operation information, the element information is extracted from the service element information according to the preset element extraction rule in order to improve the efficiency of model operation.
Specifically, the electric power operation simulation platform extracts link element information of each piece of service link information according to a preset element extraction rule, and generates a digital service model based on the extracted link element information and security regulation constraint conditions obtained by searching according to service link identifiers. By extracting the elements of the business link information by using a preset element extraction rule, the operation efficiency of the electric power operation simulation model can be effectively improved, and the operation efficiency of the whole electric power operation simulation platform is improved.
In one embodiment, the link element information includes a Role element (Role), an implement (Tool), a Method (Method), an Object (Object), a Material (Material), a Position (Position), and an Environment (Environment). That is, a business segment may be described as "a XX role in a XX environment applies a XX method to a XX object using a XX material by operating a XX implement in a XX position". And carrying out association mapping on the digital service model, a behavior sensing terminal preset in the power field and a virtual character in the three-dimensional virtual scene to obtain an initial simulation model as shown in fig. 4.
For the real world, a Role is mapped with a work card provided with an RFID electronic tag, and information such as a Role name, a Role, a right and the like is reflected; mapping Tool and Tool provided with RFID electronic tag, reflecting information such as name, number, type, validity period and the like of the Tool used in reality; the Method maps with the mobile tablet computer and reflects information such as the name of the operation task of the electronic work order and the voice for executing the operation task in reality; the Object is mapped with the operation Object equipment provided with the RFID electronic tag, and information such as the name, the number, the type, the position and the like of the operation Object equipment in reality is reflected; the Material is mapped with a Material package for installing the RFID electronic tag, and information such as Material names, types, validity periods and the like used in the operation process in reality is reflected; mapping the Position with a positioning device in reality to reflect the coordinate Position of an operator in reality; the environmental Environment is mapped with sensors such as temperature and humidity, electric field and magnetic field in reality, and the temperature and humidity, electric field and magnetic field values of the positions of operators in reality are reflected.
For a three-dimensional virtual scene, the virtual Role mapping of the Role and the three-dimensional virtual scene operation reflects the information of the name, the type, the authority and the like of the virtual Role; mapping Tool and a digital Tool library, and reflecting information such as the names, numbers, types and the like of tools operated in a three-dimensional virtual scene; the Method is mapped with simulation operation carried out in a three-dimensional virtual scene; the Object is mapped with a three-dimensional virtual model Object operated on a three-dimensional virtual scene model; the Material materials are mapped with a digital Material library, and information such as virtual Material names, types and the like used in the three-dimensional virtual scene is reflected; mapping the Position with the three-dimensional coordinates of the three-dimensional virtual scene; and mapping the Environment with the simulated humiture, electric field and magnetic field of the three-dimensional virtual scene.
In one embodiment, as shown in fig. 5, a digital service model is generated based on the element information of each link and the constraint condition of the security procedure corresponding to each service link, and the method includes the following steps:
step 502, obtaining safety procedure constraint conditions corresponding to each business link from a preset constraint condition library according to the identification information of each business link, wherein the safety procedure preset conditions are obtained by extracting elements of the safety rules corresponding to each business link according to preset element extraction rules.
The preset constraint condition library is pre-established according to the safety rules corresponding to the business links, and all the safety rule constraint conditions corresponding to the business links are stored in the preset constraint condition library.
Specifically, the electric power operation simulation platform extracts elements of the security rules corresponding to each business link according to preset element extraction rules, binds the security rule element sets corresponding to each business link together by using marking information to form security rule constraint conditions corresponding to each business link, stores the security rule constraint conditions corresponding to each business link in a preset constraint condition library, and sets the preset constraint condition library in a data storage system of the electric power operation simulation platform for storage, and can be directly called when needed. When the electric power operation simulation model is built, the electric power operation simulation platform obtains safety regulation constraint conditions corresponding to the business links from a preset constraint condition library according to the identification information of each business link.
And step 504, connecting link element information corresponding to each business link and safety regulation constraint conditions corresponding to each business link according to the step sequence of each business link in the operation information, and obtaining a business flow directed graph.
Specifically, the business process directed graph adopts a process modeling and labeling technology (Business Process Modeling Notation, BPMN) and is composed of a series of graphical elements, wherein the graphical element types comprise: flow object (Flow), connection object (Connection), swim lane (Swimlane), artificial information (artificial).
Stream objects are classified into events, activities, conditions. Events are depicted by circles, representing what happens during a business process. Events affect the flow of a flow, typically one cause (trigger) or one effect (result). Activity is represented by rounded rectangles, which are general terms for work to be handled. The conditions are represented by familiar diamonds for controlling branching and merging of the sequence streams. In addition, it may also include branching and merging of paths as a conventional option. The tag inside of which will give the type of control flow. The connection object connects the stream objects to form a basic structure of a business process, including sequential stream, message stream, association. Lanes are the division of activities into different visualization categories to describe responsibilities and responsibilities of different participants. The artificial information is added into the modeled business flow context as information remarks, which are convenient for personnel to understand, including data objects, groups and notes.
In the construction of the service flow directed graph of the embodiment, each link of the service chain is represented by the activity of the flow object, the constraint condition of the safety procedure is represented by the condition of the flow object, and the connection of each link is represented by the connection object. For business developed by multiple people in coordination, lanes are used to divide participants of different responsibilities and responsibilities.
In one embodiment, as shown in fig. 6, in the service flow directed graph, link element information (not specifically shown in the graph, but generally shown by service link 1 … n) corresponding to each service link is connected to a security procedure constraint condition corresponding to each service link according to a step sequence of each service link in the operation information, so as to obtain the service flow directed graph.
In one embodiment, the power job simulation platform may use lanes to divide activities into different visualization categories to describe responsibilities and responsibilities of different participants, generating a multi-participant business process map. As shown in fig. 7, the service operation is performed on the service job by the roles 1 and 2 in the service flow directed graph, however, the service operation required to be performed in the service link is different due to different participants, and the link element information in the corresponding service link is also different. However, no matter how many roles are involved in the business operation, if the same business operation is executed, the business knowledge base which can be referred to is the same as the business object asset full life cycle database even if the corresponding business operation is different. Thus, the business knowledge base, which can also be referred to, is used in each lane to connect the two lanes with the business object asset full life cycle database. Wherein, business system object asset full life cycle information includes, but is not limited to, ledgers, technical parameters, defects, test reports, work records, etc.
Step 506, modeling the service flow directed graph to generate a digital service model.
Specifically, the electric power operation simulation platform uses modeling language to model the service flow directed graph, and generates a digital service model.
In the above embodiment, each service link is connected with the corresponding security procedure constraint condition to generate the service flow directed graph, and the modeling language is used to model the digital service model of the service flow directed graph. Because the digital business model is built according to the business process directed graph, when the electric power operation simulation model is used for carrying out three-dimensional virtual scene exercise according to business operation data, the three-dimensional virtual exercise scene can be sequentially carried out according to the step sequence of business links in the business process, so that the whole three-dimensional virtual exercise scene is more attached to the actual operation condition, and the accuracy of determining whether the business data accords with the safety regulation constraint condition according to the exercise result can be improved.
In one embodiment, as shown in fig. 8, according to the historical service data and the initial simulation model corresponding to each service link, an electric power operation simulation model is obtained, which includes the following steps:
step 802, obtaining historical service data corresponding to each service link.
The historical service data are the historical data generated by service operators of each service link when the service operators perform service operation on each service link.
Specifically, the electric power operation simulation platform searches historical service data corresponding to each service link generated in a preset time according to the identification corresponding to each service link from a preset service database.
In one embodiment, the historical service data format may be a field table format, and after the electric power operation simulation platform obtains the service operation data of each service link each time, the electric power operation simulation platform extracts the field corresponding to the link element information from the service operation data according to the preset element extraction rule, generates the service data field table, and associates and binds the service data field table with the service link, and stores the service data field table and the service link in the preset historical service database, so that the electric power operation simulation platform is convenient for subsequent use.
Step 804, corresponding labels are set for each historical service data according to the security procedure constraint conditions corresponding to each service link, wherein the labels comprise labels meeting the security requirements and labels not meeting the security requirements.
Specifically, corresponding safety regulation constraint conditions are obtained according to service links corresponding to each historical service data, each historical service data is compared with the safety regulation constraint conditions, whether each service data meets the safety requirements or not is determined, and if so, a label meeting the safety requirements is set for the historical service data; if not, setting the history service data as a label which does not accord with the safety requirement.
In one embodiment, if each history service data is in a field table format, the corresponding security procedure constraint condition is also in a field table format. Namely, comparing the actual measurement data field table with the standard data field table, and setting corresponding labels for each historical service data.
And step 806, inputting each historical service data into the initial simulation model, and adjusting model parameters according to the model output result until the model output result meets the training ending condition, thereby obtaining the electric power operation simulation model.
The training ending condition is a condition for determining whether model training meets the requirement. When the model output result meets the inspection ending condition, the trained model can be considered to meet the requirement, and the model can be used as a final model. For example, the training end condition may be that the accuracy of the model output result is higher than a preset accuracy threshold.
Specifically, the electric power operation simulation platform inputs the obtained historical service data into an initial simulation model, adjusts model internal parameters according to the output result of the initial simulation model, and when the output result of the initial simulation model meets the training ending condition, the current model internal parameters are used for performing exercise on the service operation data, so that a correct simulation result can be obtained, and the electric power operation simulation model can be determined by the initial simulation model at the moment.
In the above embodiment, the labels are set for the historical service data of each service link to obtain the training data of the model, the training data is input into the model to train the model, and the initial simulation model meeting the training end condition is determined as the electric power operation simulation model. The electric power operation simulation model with the output accuracy meeting the requirement is determined in an iterative training mode, when the model is used for performing three-dimensional virtual operation scene exercise on the service links in the follow-up process, the early warning can be accurately performed on the service data which do not meet the constraint conditions of the safety regulations, the accuracy of judging whether the safety hidden danger exists in the service links is ensured, and the risk of occurrence of artificial responsibility accidents of the electric power operation site in the actual operation is effectively reduced.
In one embodiment, if the safety regulation constraint condition is not satisfied, performing early warning on the service operation of the service link according to the exercise result, including:
if the safety regulation constraint condition is not met, determining potential safety hazard operation in the business link according to the drilling result; and generating early warning information according to the potential safety hazard operation and the safety regulation constraint condition, and prohibiting the next business link from entering.
Specifically, when the electric power operation simulation platform determines that the service operation data does not meet the safety regulation constraint conditions according to the exercise result output by the electric power operation simulation model, comparing the exercise result with the safety regulation constraint conditions corresponding to the service links, determining the service operation with potential safety hazards in the service links, generating early warning information according to the potential safety hazard operation and standard operation in the safety regulation constraint conditions corresponding to the potential safety hazard operation, and prohibiting the service flow from entering the next service link.
In this embodiment, when it is determined that the service operation data does not meet the safety regulation constraint condition, the electric power operation simulation platform generates early warning information according to standard operation steps corresponding to the service operation data, and prohibits the service flow from entering the next service link, so that service operators are prevented from ignoring the early warning information and performing service operation of the next service link, and safety accidents are caused.
In one embodiment, as shown in fig. 9, a virtual simulation method of an electric power job is provided, and the method is applied to an electric power job simulation platform. The method specifically comprises the following steps:

And inputting the training data set into the initial simulation model, and adjusting model parameters according to the model output result until the model output result meets the training ending condition, so as to obtain the electric power operation simulation model.
The service operation data of the service link collected by the operation behavior sensing terminal is obtained, and it can be understood that the service operation data is data obtained after extraction by using a preset element extraction rule, for example, "an operator wears an insulating glove in a distance of 4m from the dotted conductor at 30 ℃ to operate (without using materials) a certain 500kV high-voltage power device".
And inputting the service operation data into a pre-constructed electric power operation simulation model, performing three-dimensional virtual operation scene exercise on the service links, and determining whether the service operation data meets the safety regulation constraint conditions corresponding to the service links. And if the safety regulation constraint condition is not met, carrying out early warning on the business operation of the business link according to the exercise result, and prohibiting the next business link from entering. For example, in the service data, the distance between the live conductor and the live conductor is within 4m, the safety regulation constraint condition is not met, the distance between the live conductor and the live conductor is 5m or more than 500kV in the operation process of an operator, at this time, the electric power operation simulation platform can generate alarm information that the distance between the live conductor and the live conductor is too close, the safety distance is kept for 5m or more, early warning is carried out, and the service process is forbidden from entering the next service link.
