Definition and display method of tree view based on cim model

Abstract

The invention provides a tree-shaped view defining and displaying method based on a CIM model. The method comprises the following steps of: S10, according to the based CIM model, constructing a tree-shaped model; S20, according to the tree-shaped model, selecting attributes to be displayed and the sequence of the attributes, and forming a view definition; and S30, loading model data according to the view definition, and forming a tree-shaped hierarchical structure. With the purpose of using the tree-shaped hierarchical structure to flexibly display the CIM model and the model data, the CIM model to be displayed is selected from CIM models, and the hierarchical structure, the attributes to be displayed and the sequence of the attributes are configured according to business requirements. A fixed code does not need to be modified after the business display requirements change or the CIM model is modified, and only by correspondingly modifying the view definition, the business requirements can be met.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method for defining and displaying a tree-like hierarchical view based on a CIM model in an electric power information system. Background technique [0002] The CIM model proposed by IEC 61970 / IEC 61968 series standards is an important standard in the field of power system management and information exchange. The CIM model defines the semantics of information exchange and enables each business system to maintain a unified semantic understanding. It is an effective way to integrate applications, share information, improve production efficiency, and reduce enterprise investment. It is the standard model of the power industry and the future of the power industry. development trend. More and more business systems are built directly based on the CIM model, but the CIM model describes a network-like association structure. In the actual business use, a tree-like hi...

Problems solved by technology

[0003] 1. With the needs of business development, the CIM model needs to be expanded. Due to the fixed code method, the expanded CIM model and model data cannot be displayed in the tree after the CIM model is expanded, and the code must be re-modified to adapt

[0004] 2. Since the business term and the description in the CIM model cannot be exactly one-to-one correspondence, it can only be solidified into the code when the interface is displayed, and cannot be modified flexibly

[0005] 3. When displaying model data in forms such as tables, it is necessary to sort the displayed attributes to facilitate business use. The traditional method has no flexible sorting rules and can only be sorted by name, which does not match the actual business needs.

[0006] 4. Although multiple tree hierarchies have similar display methods, it is still necessary to write multiple sets of different display codes, making repeated investments
