[0025] Embodiment 1

[0026] Figure 1This is a flow chart of a method for constructing a power safety knowledge graph provided by an embodiment of the present invention. This embodiment is applicable to the case where a power safety knowledge graph including a concept layer, an object layer, a state layer and a relationship layer is constructed based on power safety data. The method can be executed by a power safety knowledge graph construction device, which can be implemented in the form of hardware and / or software. The power safety knowledge graph construction device can be configured in an electronic device, which can be a terminal device or a server, etc. Figure 1 As shown, the method includes:

[0027] S110: Acquire power safety data, and process the power safety data to determine a target power safety data file.

[0028] Among them, power safety data can be understood as safety data used to regulate the operation of the power system. For example, power safety data includes: power knowledge engineering system, expert experience knowledge base, power standard data, power experience data, and it should be noted that power safety data includes structured data, semi-structured data and unstructured data. The target power safety data file can be a structured data file obtained after knowledge extraction of power safety data. The target power safety data file can include key entity information corresponding to the current power safety data, such as equipment, personnel, location, event, cause, impact, etc.

[0029] Specifically, power safety data may be collected from various data sources, including structured (such as database records), semi-structured (such as JSON, XML files) and unstructured (such as text reports, PDF documents) data. Exemplarily, power safety data may be obtained from internal data sources or external data sources, such as by periodically or in real time capturing data from various systems through API interfaces, database queries, etc. Non-digital data, such as paper reports, need to be manually entered or scanned and converted into electronic format.

[0030] It should be noted that since the safety knowledge in the power field is widely derived from structured data such as traditional power knowledge engineering systems, expert experience knowledge bases, and semi- / unstructured data such as power standards, systems, laws, regulations, and the experience of experts and technicians, it involves multiple business fields. Therefore, its knowledge can also be divided into two parts according to the degree of reuse: general knowledge and special knowledge. For example, information such as power safety regulations, safety accident handling, and fire emergency response are in demand in multiple business fields such as production, dispatching, and operation and inspection, which are called general knowledge in the power safety field; while safety knowledge in the fields of electrical safety equipment, special operations, and operating specifications is relatively special, and appears relatively single in business fields such as production, dispatching, and operation and inspection, and is identified as special knowledge in the power safety field. However, the boundary between general knowledge and special knowledge in the power safety field is often blurred. In actual operation, statistical analysis is required based on actual business to determine the boundary between general and special knowledge. Drawing on the knowledge representation case of the open domain knowledge graph, the knowledge ontology in the power field mainly includes entities, concepts, relationships, attributes, attribute values, functions, and constraints.

[0031] On the basis of the above technical solution, the processing of the power safety data to determine the target power safety data file includes: determining a data structure type corresponding to the power safety data, and determining the target power safety data file according to the data structure type.

[0032] The data structure type may be the structure type of the current power safety data, which is used to indicate whether the current power safety data is structured data.

[0033] Specifically, the collected power safety data is analyzed to identify its data structure type, such as structured data. Structured data is usually stored in relational database tables with clear row and column structures, such as equipment parameter tables, fault record tables, etc.; semi-structured data, such as JSON, XML and other formats, have a certain structure but are not as strict as structured data; unstructured data, such as text files, PDF reports, images, videos, etc., and then after determining the structure type corresponding to the power safety data, the corresponding data processing method is determined according to the structure type.

[0034] On the basis of the above technical solution, the determining the target power safety data file according to the data structure type includes: when the data structure type is structured data, standardizing the power safety data to determine the target power safety data file.

[0035] Specifically, the structured data is cleaned to remove duplicate, erroneous, missing and irrelevant data, and then after preliminary processing of the data, the processed data is standardized, such as unifying the date and time format, numerical format and text format of the power safety data, and then generating a target power safety data file based on the standardized data. The target power safety data file can be one or more structured data files, such as CSV, Excel files or database files, which contain standardized, cleaned and aggregated power safety data.

[0036] Based on the above technical solution, the target power safety data file is determined according to the data structure type, including: when the data structure type is unstructured data or semi-structured data, natural language processing is performed on the power safety data to obtain a target power safety data file corresponding to the power safety data.

[0037] Specifically, when it is determined that the current power safety data is unstructured data or semi-structured data, the unstructured or semi-structured data is first preprocessed. Irrelevant characters, punctuation marks, and stop words are removed through text cleaning, and the text is segmented into words, phrases, or sentences, and then the part of speech (such as noun, verb, adjective, etc.) is labeled for each word. After the preprocessing is completed, the named entity recognition technology in natural language processing is used to identify entities related to power safety from the text, such as equipment name, fault type, location name, etc. After the entity is identified, the relationship between the entities is further extracted. For example, the fault time and location of the current power equipment, etc. After the information extraction is completed, the extracted data is structured, for example, it is converted into a JSON object. It should be noted that the structured data should contain key information related to power safety, such as equipment ID, fault type, occurrence time, location, impact range, etc., and then based on the structured data, a target power safety data file is generated. The target power safety data file can be one or more files, such as CSV, Excel files or JSON files, which contain power safety information extracted and structured from unstructured or semi-structured data.

[0038] S120. Determine a graph structure level corresponding to the target power safety data file, and establish the power safety knowledge graph according to the graph structure level and the target power safety data file.

[0039] Among them, the graph structure levels include concept layer, object layer, state layer and relationship layer.

[0040] Specifically, knowledge representation is the basis and premise for knowledge application. From the perspective of the hierarchical framework, the power safety knowledge representation model is divided into four levels from top to bottom: concept layer, object layer, state layer and relationship layer. The concept layer is mainly used to express the concept description in the power safety knowledge system; the object layer is used to express the components of the power safety knowledge system, including specific production enterprises, production personnel, power facilities, etc.; the state layer includes the operation of equipment, whether safety knowledge is followed, and the accident handling caused by non-compliance; the relationship layer is used to express the relationship type in the power safety knowledge representation model. The basic components and their relationships of the power safety knowledge model are uniformly expressed through the concept layer, object layer, state layer and relationship layer.

[0041] like Figure 2 As shown in the figure, the concept layer mainly describes the concept classification system of power safety knowledge. The concept classification system includes various categories: safety regulations, accident handling, safety of electrical safety equipment, operating specifications and fire emergency safety, etc. Among them, safety regulations include: Work Safety Law, Electricity Law, Electricity Facility Protection Regulations, etc., and also include common sense of work safety, safety colors and safety signs, fire safety and emergency safety knowledge, etc. The knowledge in the concept layer exists independently in the form of nodes, and there are semantic relationships between different concepts.

[0042] According to the conceptual classification system of power safety knowledge, power safety knowledge is composed of many independent objects, so power safety knowledge can be represented from different angles. Safety regulations guide the production process of the entire power enterprise, and the objects include production enterprises and production personnel; at the same time, there are different safety rules and requirements for different electrical safety equipment; any safety accident will involve accident personnel and power equipment; there are also corresponding fire emergency plans, which constitute the objects of power safety knowledge. Let E be the subject of power safety knowledge, O be the object related to safety knowledge, and k represent the number of objects, then E can be expressed as: E = <O1,O2,…,O k >.

[0043] The state layer is the specific changes, actions or records of an object in time and space. According to the development process of an event, the object can be decomposed into different states, and the changes of the object can be represented by a set of states. The development process of the event itself can be expressed through the different states of the object. Let O be an object related to security knowledge, S be the state of object O, and k represent the number of states contained in the object, then it can be expressed as: O = <S1,S2,…,S k >.

[0044] The relationship layer can be the evolution process of the power safety knowledge system in the safety production process, which is composed of the connection of different object states in time and space. Process-based modeling is based on the evolution of power safety knowledge, and the evolution stages of different objects in the event are hierarchically abstracted. Therefore, different states of the same object are sequentially connected according to the time relationship to form a state sequence. o = o1 ,S o2 ,…,S ok >; Among them, S ok Represents the process of composing an object P o The state sequence is the basic unit of the actual operation of the power safety knowledge system. The state sequences of multiple objects together constitute the power safety knowledge system.

[0045] Taking typhoon disaster events as an example, the various elements that constitute typhoon disaster events are often related. Objects can be concepts, elements, and features, and relationships also focus on the connection between multiple objects. The determination of a relationship requires connecting at least two objects, which can be expressed as: R = <O A ,r,O B >; Among them, O A and O B These are different objects in the power safety knowledge system: r means O A and O B The type of relationship that exists between nodes. The relationship layer defines the types of relationships contained in the knowledge graph. In the knowledge graph, relationships can be seen as edges connecting two nodes. Relationships are used to connect concept nodes, object nodes, and feature nodes, etc.

[0046] On the basis of the above technical solution, the determination of the graph structure level corresponding to the target power safety data file includes: establishing a mapping relationship between the object layer and the target power safety data file based on a preset power safety object; identifying status information and relationship information associated with the preset power safety object from the target power safety data file based on the mapping relationship; filling the status information into the status layer corresponding to the preset power safety object, and filling the relationship information into the relationship layer corresponding to the preset power safety object.

[0047] Among them, the preset power safety objects can be understood as pre-set power safety management objects, for example, they may include production enterprises, staff, accident personnel, power facilities, safety signs and fire-fighting facilities.

[0048] ​Specifically, it is clarified that the key objects in the field of power safety include production enterprises, staff, accident personnel, power facilities, safety signs and fire-fighting facilities, etc., and the above objects will be used as the basis of the graph structure to construct the object layer, and then establish the mapping relationship between the object layer and the target power safety data file based on the preset power safety object, such as matching the preset power safety object according to the keywords in the target power safety data file, and then establish the mapping relationship between the object layer and the target power safety data file according to the matching result, and identify the state information and relationship information associated with the preset power safety object from the target power safety data file according to the mapping relationship. It should be noted that the state information may include the operating status of the equipment, the specific description of the fault, the safety status of the location, etc.; the relationship information may include the connection relationship between the equipment, the association between the fault and the equipment, the time sequence, etc. Finally, the identified state information is filled into the state layer corresponding to the preset power safety object, and the identified relationship information is filled into the relationship layer corresponding to the preset power safety object.

[0049] On the basis of the above technical solution, after establishing the power safety knowledge graph according to the graph structure hierarchy and the target power safety data file, it also includes: regularly updating the power safety data according to the data update cycle, and updating the power safety knowledge graph according to the updated power safety data; and / or, obtaining feedback information corresponding to the power safety knowledge graph, and adjusting the power safety knowledge graph according to the feedback information.

[0050] The data update cycle may be a preset update cycle, for example, updating the power safety data regularly every fifteen days. The feedback information may be understood as information corresponding to the power safety knowledge graph fed back by the safety management personnel.

[0051] Specifically, according to the characteristics and needs of power safety data, a reasonable data update cycle is set, such as daily, weekly or monthly, and then: when the update cycle arrives, the latest power safety data is collected from data sources (such as sensors, monitoring systems, manual reports, etc.), and the status information and relationship information related to the power safety object are extracted from the updated data, and the extracted information is compared with the existing power safety knowledge graph, and the corresponding status layer and relationship layer content are updated or added; it is also possible to collect user feedback on the use of the power safety knowledge graph through a user interface or questionnaire survey, and then identify problems or deficiencies in the graph based on the feedback information, and make corresponding adjustments and optimizations to the power safety knowledge graph based on the problems.

[0052] The technical solution of the embodiment of the present invention obtains power safety data, processes the power safety data, determines the target power safety data file, and then determines the graph structure level corresponding to the target power safety data file, and establishes the power safety knowledge graph according to the graph structure level and the target power safety data file. Based on the above technical solution, the power safety knowledge representation model is divided from top to bottom into the concept layer, object layer, state layer and relationship layer, and then the basic components and relationships of the power safety knowledge model are uniformly expressed through the power safety knowledge graph, and the scattered distribution of power safety knowledge and the data with diverse structures are effectively processed and organized, providing more intelligent protection for the production safety, equipment safety and safety education of power enterprises.
