Remote retrieval method for complex primitives in heterogeneous system picture

Abstract

The invention discloses a remote retrieval method for complex primitives in a heterogeneous system picture. The method comprises the steps that the complex primitives in different systems are converted into a CIM-SVG standard format in a unified mode, and a static shape and dynamic data of each type of primitives are defined; all systems of a retrievee transmit a picture file containing the complex primitives to a system of a retriever system according to the DL476 standard; the retriever analyzes the received picture file and then displays the picture file in the system of the retriever; the retrievee transmits the data associated with the complex primitives to the system of the retriever in a specified format according to the DL476 standard; the retriever receives the data associated with the complex primitives and then displays the data in the system picture. According to the method, a dynamic component and a data message are combined to realize drawing of a component graph obtained after refresh of the data of the complex primitives, and therefore the retrieval technology that the complex primitives are remotely retrieved in the heterogeneous system picture is realized.

Description

technical field [0001] The invention relates to the field of electric power dispatching automation systems, in particular to a method for remotely accessing complex graphic elements in heterogeneous system screens. Background technique [0002] The traditional power dispatching automation system can only view the screen files customized by the system, and cannot view the screens of different manufacturers and systems. [0003] With the development of technology, graphics standards based on CIM-SVG and CIM-G have emerged. Different manufacturers or systems can import and export plant model diagrams through the above two standards, so as to realize offline export of pictures between heterogeneous systems, Import and realize the display of static images, but cannot realize the real-time refresh of dynamic data. [0004] In recent years, a remote access technology based on CIM-SVG or CIM-G graphics standard and DL476 data standard has been proposed, which realizes real-time scr...

[0003] With the development of technology, graphics standards based on CIM-SVG and CIM-G have emerged. Different manufacturers or systems can import and export plant model diagrams through the above two standards, so as to realize offline export of pictures between heterogeneous systems, Import and realize the display of static pictures, but cannot realize real-time refresh of dynamic data

[0004] In recent years, a remote access technology based on CIM-SVG or CIM-G graphics standard and DL476 data standard has been proposed, which realizes real-time screen browsing and data refresh between heterogeneous systems, but it is also limited to screens containing basic primitives, such as One-time wiring diagram of the factory station, interval sub-graph, etc., when there are complex graphic elements in the screen, such as pie charts, histograms, curves, etc., because the implementation of different manufacturers is too different, it is impossible to view the screen remotely in real time without any difference. screen data
