In the present invention, disclosed a kind of in the model splicing process, at first with the method for level type structrual description splicing both sides (model to be spliced with last time model splicing result) structure, the purpose that adopts this structure is to prepare for follow-up quotient of difference based on model cutting on the topology coloring basis and model variation, also is to have guaranteed that spliced model can the hierarchical relationship Structure Conversion from splice program be the final mask that meets the IEC61970/CIM standard in addition.
At first be that CIM/XML model to be spliced is resolved in the program buffer 1, and with its arrangement for level type structure shown in Figure 4, in Fig. 4: except the voltage type object of the non-hierarchical structure of overall type, for level type relation, has the container class feature between between company, sub-control area, factory station, electric pressure, physical node and the equipment (generator, load, switch, disconnecting link, cutter, capacitive reactance device, bus) and factory station, transformer, the Transformer Winding.And topological connection relation is by the incidence relation between device port and physical node, device port and the equipment, and then has obtained related between equipment and the physical node, and is written in the middle of the Attribute domain of device object.
Hierarchical relationship formation method is as follows:
(a) utilize map＜hint obliquely at, set up the resource identifier rdfid of part object among the CIM/XML and the relation of hinting obliquely at of sequence number, wherein, man-to-man map＜string, int〉type relation has: voltage type, company, sub-control area, factory station, electric pressure, transformer, physical node; And the map＜string of one-to-many, vector〉type relation has: hinting obliquely between the rdfid of equipment and the rdfid of port;
(b) circulation object is set up hierarchical relationship structure between object and its container, available two-dimensional array relation or level type pointer relationship description according to the rdfid of the rdfid of container MemberOf_ under it and other incidence relation and topological relation.The individual layer circulation can realize the non-nesting process;
In the present invention, disclosed a kind of method of model cutting.The purpose of cutting is that the model part of will not return model area side to be responsible for beyond the border cuts away, the one, meet All Control Center and only be responsible for the management expectancy of bounds with inner region, also be the needs that guarantee not have in the spliced model redundance unit in addition, also dock the condition of having created simultaneously for the incremental computations of back and model.
Model cutting has then adopted the method for topology coloring.At first, when reading edge device information, extract simultaneously and the significant factory of model area correspondence to be spliced stands and the position of electric pressure, as with respect to this regional internal indicator, color number composed give corresponding physical node, and the priming color of other physical node number is 0; Utilize the BFS (Breadth First Search) method, check the color number of the ports physical node of circuit, transformer, if any the uneven situation of color, then carry out color mobile (edge device does not allow color to flow), and the color of all of the port physical node number composed identical value, simultaneously the color of other related physical node under the electric pressure of new assignment physical node place factory station number is also composed identical value, method is with " closing " state processing with equipment such as switch tools;
After topology coloring finishes, need to check the cutting situation of model, the method of checking is: any one and the relevant edge device in model to be spliced region, if the color of the port that they are all number is not 0, illustrate that the existing boundary device definition is incomplete, can not will separate inside and outside the model area scope, alarm is withdrawed from.And if the color of its all of the port number all is 0, illustrate that then existing boundary equipment is in isolated state in model, or the location definition in its significant zone is inaccurate;
Fig. 5 is spliced into example with two regional models, has showed the model cutting process, (a) is the original description of regional 1 model, (b) is the model after 1 cutting of zone, (c) is the model after 2 cuttings of zone, (d) then is zone 1 and zone 2 spliced models;
The meaning of model cutting also is, by and coupling with the quotient of difference of object in the same area scope among the internal model after the cutting and the model splicing result last time, obtain the change information of this regional model, and do not comprise comparison beyond any zone, thereby also just not to the requirement of device object overall situation uniqueness, require as long as satisfy uniqueness in the zone of model to be spliced, this is to satisfy fully in the model of district system to be spliced.
In addition, model after the cutting is after increment changes renewal world model, originally the object naming in the regional model is inherited, this provides assurance for the figure conversion, after the graph data of former control center is used the SVG format conversion, only need reorientate for foreground object wherein, just can on spliced full model basis, set up new data and relation between objects according to the name in past; Equally, when the metric data of the real-time collection of obtaining control center to be spliced forwarding by communication protocol (as TASE.2), on spliced full model basis, also can successfully reorientate and obtain by the succession of name in data of setting up on the local model and the corresponding relation between the object.Above process all is to finish automatically, and fully based on standing state, does not increase extra model object and revise, and this just provides real operability for realization of the present invention, particularly for sweeping control system.
With respect to the result of model splicing last time in the buffer zone 2,, therefore do not need to carry out the topology coloring process of model cutting owing to when last time model splicing is finished the write data storehouse, the sign of relevant range can be recorded among the object of database;
In the present invention, disclosed the incremental computations method that a kind of model changes.The relative stability that splicing back full model changes is very necessary, because the global change of model has lot of data storehouse additions and deletions operation (generally needing simultaneously to commercial data base and real-time data base operation) on the one hand, influence efficient, can make also that in addition original data and relation between objects can constantly change along with the splicing of model, influence the original corresponding relation of figure and data communication, need to rebuild, also can cause data interruption simultaneously.Therefore adopt the incremental computations method of model variation to be necessary with Practical significance.
Incremental computations is based on matching process, the both sides of coupling, and one is inside and the borderline region that the subject area new model is newly spliced in representative in the aforementioned buffer zone 1, the opposing party then is the full model result of last time model splicing, in buffer zone 2.Why select the Zone Full of buffer zone 2, rather than the original scope corresponding with zone to be spliced, mainly be situation about considering after the border changes, to reduce the scope that increment changes as far as possible.
Matching process adopts the order of carrying out to the bottom from the top of buffer zone 1 hierarchical relationship, and the coupling flow process is seen Fig. 3.At first,, arrive mechanical floor (as: switch, disconnecting link, ground connection disconnecting link, load, generator, bus, capacitive reactance device) again to the electric pressure layer from factory's station layer (company, sub-control area, voltage type adopt global registration) beginning.Transformer and electric pressure also occupy layer below, factory station with layer.Need to prove that the coupling of transformer also comprises the winding part that it is associated, have only that all the match is successful, could represent that coupling fits like a glove, otherwise together handle as coupling is unsuccessful.
If the match is successful, just the key word of buffer zone 2 database objects to be composed to the corresponding object in XML buffer zone 1 inside and the borderline region, this XML object obtains the identity that has existed simultaneously in database; If coupling is unsuccessful this XML object is brought in " set up and be equipped with tabulation "; The upper strata object does not match and will think that its lower floor's object does not match, and does not need to continue downward coupling yet.It is emphasized that object range in " set up be equipped with tabulation " only limits to inside and the borderline region model part in the buffer zone 1, promptly color number is not 0 object and container thereof, does not comprise the outside; Object range in " subtracting list of devices " then is limited to after last time model splicing was finished in the buffer zone 2 the identical object range (containing last time border) of identifier with the zone of this splicing, rather than the world model's scope in the buffer zone 2.Unsuccessful this section object of all couplings is all brought in " subtracting list of devices ";
In " set up and be equipped with tabulation " of Fig. 2, the base attribute of object type and title description object, the incidence relation of unidirectional monodrome described in Container Type and key word;
In " the subtracting list of devices " of Fig. 3, can in database, delete original object according to object type and key word;
In the present invention, disclosed that a kind of model object upgrades and based on the model docking calculation on the topological relation.After the incremental computations that model changes finishes, according to " subtracting list of devices ", according to the object to the order deletion model splicing system at top bottom hierarchical relationship; Again according to " set up and be equipped with tabulation ", according to from the hierarchical relationship top order to the bottom the model splicing system, insert new object, and the key word of new object composed to the object in the XML buffer zone 1, in conjunction with front coupling assignment procedure, buffer zone 1 interior zone object all gets access to the key word in the database, for next step is got ready to the model butt joint that object in the splicing database carries out on the topological relation according to key word.
After finishing additions and deletions operations, the full model object of model splicing all exists in the database of splicing system, and neither lacks also not redundantly, does not just also connect as a whole on topological relation;
The object range of topological relation correction be in the buffer zone 1 on the physical node color number be not 0 associate device, refresh the topological identification number that color that this equipment has number is not 0 physical node according to its key word.For edge device, because it number is not 0 with respect to the color on the physical node of this area side to be spliced, so be corrected, and the color on the physical node in the outside number is 0, thus do not revise, and when the model in splicing offside zone, when refreshing the topological relation of this edge device, just in time opposite.The natural order of physical node (ConnectivityNode) number when the desirable CIM/XML of topology identification number resolves, or on this sequence number basis, add area code in a high position, as: area code * 1000000+ nature sequence number; Can guarantee that the overall situation is unique in spliced system model;
After edge device definition changed, the result who last time the imported model partly of corresponding region might not dock in the CIM/XML model that cuts out with new border and the database, causes the model off-the-line.But behind the CIM/XML model of the new reflection border variation in another zone that imports and the border changing unit is associated, the splicing result in the database will become an integral body that is consistent with virtual condition.
