Design and realization of operation mode entity for electric power communication network

Entity is the basic element of graphics, in practice, a graph often has lots of entities. Reasonable definition and use of entity is the key of drawing. According to the needs of drawing operation mode graphics, this paper uses object-oriented idea to design a set of entities which encapsulate parameter information of communication equipment. This changes the previous drawing mode which separated the graphics and data, improves work efficiency, realizes informationization and standardization of operation mode graphics, and also provides a good data interface for mode management systems.
