Therefore, different contents can be displayed in a personalized way aiming at different crowds.
In this embodiment, the transformer substation comprehensive control platform operates on a terminal device, and the terminal device can adaptively adjust the size and brightness of each specific module in the graphic configuration module when looking up the content of the transformer substation comprehensive control platform according to different roles; for example, when the operation and maintenance personnel check the type, the emergency degree, the distribution area, the position coordinates and the like of the box-type substation to be overhauled, the emergency degree and the position coordinates of the box-type substation to be overhauled can be displayed in an enlarged mode, or the box-type substation to be overhauled which needs emergency treatment is highlighted; therefore, operation and maintenance personnel can see the box type transformer substation needing emergency treatment in time, and the risk of damage of the box type transformer substation is reduced. It can be understood that, in the present solution, the specific module and the specific content are not limited to be displayed in an enlarged or highlighted manner, and the relevant staff may be reminded in different colors, which is set according to the actual application scenario.
Based on the above embodiment, referring to fig. 2 and fig. 3, the comprehensive intelligent city management and control platform 40 displays the summarized classified data of the data analysis system 30 in real time based on the SVG online vector graphics architecture. It should be noted that SVG (Scalable Vector Graphics) includes a DOM API layer, an object management layer, an interaction operation layer, an event processing layer, a presentation operation layer, and a data interaction standard interface. Compared with JPEG, BMP image and AutoCAD file, the said method occupies less space and has high compressibility and is favorable to network transmission. In addition, the SVG online vector graphics has the characteristics of infinite amplification, no distortion, support for displaying and editing of a plurality of layers, support for custom graphics primitives, multi-browser compatibility and the like.
In this embodiment, the DOM API layer is the lowest layer of the architectural design. Based on various display schemes of the browser, the elements are finally converted into DOM (Document Object Model) Object element expressions. The objects comprise a rectangular Rect element, a Circle element, a Line element, an Ellipse Ellipse element, a Path element, a Text element and the like in the SVG and other object elements supported by various SVGs. One standard SVG graphics file format is as follows:
<xml version＝"1.0"standalone＝"no"？>
<svg width＝"100％"height＝"100％"version＝"1.1" xmlns＝"http://www.w3.org/2000/svg">
<circle cx＝"100"cy＝"100"r＝"100"stroke＝"black"stroke-width＝"2" fill＝"green"/>
</svg>
the standard SVG graphics file defines a circle with a radius of 100, with center coordinates (x, y) of (100 ), a circle border width of 2, border color black, and filled in with green. This SVG file canvas is completely full of containers, i.e., both width and height are 100%.
In order to be compatible with the operation of DOM objects in multiple browsers, the system utilizes the open source Javascript frame jQuery which is widely used at present, and can be well compatible with various types and versions of browsers, such as IE9/IE10/IE11, chrome and Firefox browsers, and the like.
In this embodiment, the object management layer includes a base map SVG file, a primitive, a layer, a global variable, and an implemented data structure class object. The graph, the layer and the graphic element have an inclusion relationship. A graphic object represents an abstract model of attributes and related operations contained in the graphic, and the abstract model comprises a layer object list used for representing how many layers are distributed under the graphic; each layer contains a primitive object list indicating how many primitives are arranged on a layer, and the relationship between them is shown in fig. 3.
Further, the primitive is a core element of the whole design, and is one of basic elements forming the layer and the SVG graphic file. The system is composed of SVG basic elements such as Circle, line, path and the like, and has attributes such as width, height, coordinate position and the like, and related methods such as position movement, attribute assignment, mouse events and the like. The system produces and provides a plurality of primitives by itself, including basic common primitives such as straight line primitives, broken line primitives, circular primitives, rectangular primitives, text primitives, real-time data tag primitives and the like, and special primitives such as fan primitives, arrow direction primitives (which can also represent the direction of wind flow) and the like for various subsystems.
For the definition of the primitive, the system is operated by the common attribute and common operation of the primitive, and other various self-defined primitives inherit the common primitive. The attribute field of the common primitive is shown as the common attribute of the primitive in table 1, and the common operation and name are shown as the common operation method of the primitive in table 2.

The group formed by a plurality of graphic elements is called a layer in the system. A plurality of graphs are defined on the same father object, the size proportion, the display condition and the like of the primitives are controlled uniformly, and the group of primitives are convenient to operate uniformly. The graphic object also includes some specific attributes and operations, as shown in table 3 layer attributes and table 4 layer operation methods, respectively.

In this embodiment, the interactive operation layer mainly provides basic operations on the graph, and is configured to receive corresponding events of the event processing layer, combine the events with the selection object, and perform related transaction processing, where the events include a base graph operation interface, a layer operation interface, a primitive operation interface, and some internal operation interfaces. The base map operation interface is shown in the base map operation interface of table 5, and includes an operation interface for SVG graphic attributes and an operation interface for graphic display, and is intended for users to operate and control the SVG base map. The layer operation interface and the primitive operation interface are respectively shown as the layer operation interface of table 6 and the primitive operation interface of table 7.

The operation interfaces of the base map, the layer and the primitive are similar to the operation methods of the base map, the layer and the primitive, because the operation interfaces actually carry out one-step encapsulation on the operation methods of the objects, external codes are convenient to call, and the independence among the base map, the layer and the primitive can be ensured. In addition, the system also provides a part of internal operation interfaces for data processing. The display of the online configuration graph can not be separated from the real-time data and state information of various devices, and how to bind the data information to the configuration graphics primitive or the graph is realized by the internal operation interfaces. Their main functions are to initialize graphics, obtain various real-time data and bind the data to the related primitive objects, and the main part operation is as shown in table 8 below.

In this embodiment, the event processing layer is a key for implementing the whole design, and receives a relevant operation of a user, and feeds back the operation to the primitive, the layer or the base map, thereby implementing dynamic display of the graphics and data and completely displaying the whole production flow. Events mainly responded by the event processing layer are mouse clicking events, mouse dragging events, zooming-in and zooming-out events and the like.
