Abstract
The invention aims to provide a grid equipment graphic element allocation method. The method includes: establishing a spatial GIS (geographic information system) graphic element allocation model comprising an equipment legend table, a graphic element style rule table, and a style table; finding out corresponding legend styles according to equipment legend rules and rendering in the graphic element allocation process. The grid equipment graphic element allocation method which is more flexible and softer to expand is provided according to China southern power grid GIS graphic element specifications and is provided in order to overcome the defects of the existing grid GIS graphic element allocation method. A graphic element allocation model and a correspondence amongst each style of grid equipment, graphic element display rules and graphic element symbols are established according to a relational database, so that various grid devices under the GIS system platform can be conveniently monitored and maintained in real time.
Description
Technical field
The present invention relates to Spatial GIS (GIS) and electric network information maintenance technology field, relate in particular to the collocation method that a kind of " generating-transmission of electricity-power transformation-distribution " full electric network equipment pel is played up at GIS platform symbol.
Background technology
Along with GIS technology develops in electrical network field, each province, districts and cities set up electrical network Spatial GIS (GIS) successively, because first stage of construction grid equipment pel does not have unified standard, as figure metasymbol (symbol shape, the color of transformer, fill type etc.), the graph style of transformer (point, line, face), grid equipment represents all different at each electrical network Spatial GIS (GIS), be unfavorable for setting up unified GIS platform.
Afterwards, south electric network company limited formulated relevant power grid GIS pel standard, had stipulated primitives classification and the code of power grid GIS, comprised pel title, state, graphical symbol.But may not exclusively meet the business demand of prefectures and cities' personalization, at this moment just need the grid equipment pel collocation method of an extensibility, realize grid equipment pel flexible configuration and represent.
At present, power grid GIS platform device pel represents, and is mainly that following two kinds of modes realize: the configuration file of writing the filtration of code implementation rule and system reading and saving legend rule.
Code implementation rule filters: this is very original implementation, it is by code, to realize screening to play up that power grid GIS platform device pel represents, as on-load switch, the on off state of code judgement on-load switch, being that " opening " just played up on map and represented with green switch symbols, is that " closing " just played up on map and represented with red switch symbols.This mode maintenance cost is high, is not easy to configuration and later expansion.
Configuration file is preserved legend rule: this mode is mainly saved in binary file or XML file, extensibility, structuring and the cross-platform feature of utilizing XML, the pel allocation models of foundation based on XML, every class grid equipment definition pel is represented to rule and corresponding figure metasymbol, but device category is various, corresponding multiple rule, is not easy to check and safeguard.
Summary of the invention
The present invention be directed to the deficiency of existing power grid GIS pel collocation method, follow south electric network GIS pel standard for one of proposition, the grid equipment pel collocation method of more flexible, flexible expansion.By adopting relational database to set up pel allocation models, set up every class grid equipment, pel shows rule and figure metasymbol three corresponding relation, thereby is convenient to all kinds of grid equipments under generalized information system platform to carry out Real-Time Monitoring and maintenance.
The technical scheme that the present invention specifically takes is as follows:
A pel collocation method, comprises following content:
One, build GIS pel allocation models:
Pel allocation models comprises equipment legend table, pel style rule table, style sheet.
1) equipment legend table: for recording the adoptable legend item of every kind equipment, every kind equipment all need have at least one legend item at legend table, this legend item records this kind equipment and adopts which kind of pel style rule, one kind equipment can corresponding a plurality of legend items (as transformer station divides according to electric pressure state, a kind of legend of use of 500kV, the another kind of legend of 220kV, 110kV adopts again a kind of legend of energy), and use sequence number to record sequencing.
2) pel style rule table: rule list records every kind equipment screening rule (if the on off state of on-load switch=" opening " is a rule, a kind of pattern in corresponding style sheet), style rule table and various style sheet are one-one relationships, every kind of corresponding a kind of pattern of rule.
3) style sheet: the figure metasymbol of recording unit, comprise a pattern, line pattern, face pattern and dimension style, record every kind equipment corresponding point, line, the pattern of face and mark, also comprises color, size is filled type, transparency, the bitmap of connection or font etc.
Two, pel layoutprocedure
Pel layoutprocedure is found out corresponding pel pattern according to equipment drawing convention and is played up, and specifically comprises as follows:
1) according to device type title, at equipment legend table, search corresponding pel style rule, use pel style rule sequence number ascending sort, draw pel style rule ID set.
2) according to pel style rule ID set, in pel style rule table, search corresponding rule.
3) circulation searching regular collection out.
4) find out the figure metasymbol that equipment is corresponding, and play up.
Accompanying drawing explanation
Fig. 1 is pel allocation models figure;
Fig. 2 is the process flow diagram of pel layoutprocedure.
Embodiment
Below in conjunction with accompanying drawing, grid equipment pel collocation method of the present invention is described further:
One, build GIS pel allocation models:
As shown in Figure 1, pel allocation models comprises equipment legend table, pel style rule table and style sheet.
1) equipment legend table: every kind equipment all need have at least one legend item at legend table, record adopts that pel style rule, one kind equipment can corresponding a plurality of legend items (as transformer station divides according to electric pressure state, a kind of legend of use of 500kV, the another kind of legend of 220kV, 110kV adopts again a kind of legend of energy), and use sequence number to record sequencing.(design is in Table 1)
Table 1
2) pel style rule table: rule list records every kind equipment screening rule (if the on off state of on-load switch=" opening " is a rule, a kind of pattern in corresponding style sheet), style rule table and various style sheet are one-one relationships, every kind of corresponding a kind of pattern of rule.(design is in Table 2)
Table 2
3) style sheet: comprise a pattern, line pattern, face pattern and dimension style, record every kind equipment corresponding point, line, the pattern of face and mark, comprises color, size is filled type, transparency, the bitmap of connection or font etc.(designing in Table 3,45,6)
