Abstract
The invention discloses a whole-line station yard graph graphical interface system which constructs graphs based on XM L language, has rich and detailed graphs, strong data readable expandability and good interactivity and is more convenient to use.
Description
Technical Field
The invention relates to a graphical interface system, in particular to a full-line station yard graph graphical interface system in the field of rail transit.
Background
At present, ATS (automatic train monitoring system) station yard graph generation method is mainly based on components. The following description takes an ActiveX component under the Windows platform as an example.
The site map based on the ActiveX mainly comprises different controls, and the basic composition controls comprise a section control, a turnout control, a signal control, a platform control, a train number window control and other controls. Firstly, a reusable station yard graph control needs to be designed and is realized by codes; the task that the design of a reusable component needs to accomplish first is to design the property. The attributes of the site map component are classified into static attributes and dynamic attributes. Static properties refer to some component properties that can be modified when the site map is drawn, which are immutable at system runtime, i.e., static with respect to the running system, once the site map is loaded and generated; the dynamic attribute refers to an attribute that is continuously changed in the running process without setting or only setting by default when the station yard graph is drawn, that is, an attribute that is dynamically changed in the running process. After the components are available, the realized components can be spliced into an actual station yard graph, the static attributes of the components and the positions of the controls are stored, and the station yard graph can be generated by loading and drawing the controls once according to the stored files when the system is operated.
The disadvantages of the component-based approach to generating a site map are: poor flexibility, poor reusability, difficult maintenance and poor compatibility. Redesigning new components once new lines are needed to add new devices; and if the same device needs to have different expressions, different components are needed to realize the device; code recompilation must be modified to generate new or modify old components; such systems are difficult to be compatible with other software.

The graph XM L defines an Icon of the type:
circle: solid or hollow round;
l ine, line segment;
and Rect: the solid rectangle is different from the line segment, the line segment can be oblique line, and the solid rectangle can only be in horizontal or vertical direction;
text: a text;
polygon: solid or hollow polygons.
The CUIT may decide whether the Icon needs to be displayed in units of interlocking zones. In a typical application, a control center workstation needs to display all the Icon of the interlocking area of the whole line, and a station or a vehicle section only needs to display the Icon of the station and the adjacent station.
The reference coordinate system for all Icon coordinates is shown in fig. 3. The Icon coordinate system uses the upper left corner of the full line yard graph as the origin instead of the upper left corner of the interlocking zone where the Icon is located. Through the number of the interlocking zone where the Icon is located, the client system can acquire all the icons of a certain interlocking zone, further calculate the boundary of the interlocking zone, and control the display of the Icon on the screen of the client system through operations such as translation and the like.
The main purpose of Icon is to display the Device's real-time status. The real-time state of the Device is represented by the real-time state of the Device representation code bits.
The Icon comprises a logic table for controlling dynamic display of the Icon, and the logic table comprises a Simple L g-ictable (Simple logic table) and a Complex L g-ictable (Complex logic table), wherein the Simple L g-ictable adopts a truth table to define a Simple dynamic display scheme of a certain Icon, and the Complex L g-ictable adopts a Boolean logic expression to define a Complex dynamic display scheme of the certain Icon.
When an Icon is only displayed statically, the Icon is not associated with a logical table (the index of the logical table corresponding to the Icon is 0), and only displays a default color without dynamic effect. That is, there will not be an empty logical table.
The Icon list element Icon contains 1 attribute, namely, an Icon Index, as shown in table 17.
Table 17Icon contains attributes
| Attribute name | Type (B) | Number of | Main key | Description of the invention |
| Index | int | 1 | Is that | Icon index, starting with 1. |
The Icon list element Icon includes 5 elements, which are respectively a layer element (L evel) to which the Icon belongs, an Icon Type element (Type), a default color index element (ColorIndex), a logical table element (L ogivtable) associated with the Icon, a device index element (devicendex) associated with the Icon, or a button index element (button index) associated with the Icon (either devicendex or button index), a filled or unfilled circular picture element (Circle), a line segment Icon element (L ine), an element (Rect) filled or unfilled rectangular Icon, a Text box Icon element (Text), or a filled or unfilled polygonal Icon element (Polygon) (five selected one of Circle, L ine, Rect, Text, and Polygon), as shown in table 19.
Table 18Icon contains elements
The logical table element (L ogicTable) associated with the icon contains 1 element, selecting between a Simple logical table element (Simple L ogicTable) and a Complex logical table element (Complex L ogicTable), as shown in table 19.
Table 19L ogicTable contains elements
A Simple logic table element (Simple L ogicTable) establishes a correspondence of a set of code bits to an Icon color, for N code bits, there is 2NPossible combinations, each associated with a colour, for receiving a code shapeWhile dynamic, Icon can dynamically refresh color.
The Simple logical table element (Simple L ogicTable) contains 2 elements, respectively, a code bit name list element (BitName) and a color index list element (ColorIndex), as shown in table 20.
Table 20Simple L ogicTable contains elements
| Element name | Type (B) | Number of | Main key | Description of the invention |
| BitName | string | [1,∞) | Whether or not | Code bit name List |
| ColorIndex | int | [2,∞) | Whether or not | Color index list |
The following is one example of a simple logical table element:
when N exceeds 8 (2)8256), the truth table mode of the simple logic table is too complex, and the boolean logic expression mode of the complex logic table is adopted, so that the code bit combination which is impossible to input can be avoided, and the code bit combination is more effective when the code bits are too much, but the mode is not as intuitive as the truth table.
When all Boolean logic expressions are computed to be 0, the Icon displays the default color. Obviously, it is impossible to have the calculation result of more than 1 boolean logic expression in a complex logic table associated with an Icon as 1 in any code bit combination, because one state cannot adopt two color realities at the same time.
The Complex logic table element (Complex L g ictable) contains 1 element, namely, a boolean logic expression list element (L g icexpress), as shown in table 21.
Table 21Complex L ogicTable element
| Element name | Type (B) | Number of | Main key | Description of the invention |
| LogicExpression | complexType | [1,∞) | Whether or not | Boolean logic expression list |
The boolean logic Expression list element (L g icexpresson) includes a boolean logic Expression element (Expression) consisting of a code bit index and a color index element (ColorIndex) that the icon displays when the boolean logic Expression is true, as shown in table 22.
Table 22L g omicExpression contains elements
The Boolean logic expression syntax is:
E->E1+E2|E1*E2|！E1|(E1)|1|0
boolean operator: + (or), a, and! (not)
The Boolean constant: 1 (true), 0 (false)
Specific examples are as follows:
example 1:
| A ((P2901 occupied) | (P2901 locked)) + ((P2901 occupied) | (P2901 locked))
When P2901 occupancy is 1 and P2901 lock is 0, the value of the above boolean expression is 0
| A T2808 occupancy
When T2808 occupies 0, the value of the above boolean expression is 1
