Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention being described in further detail, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Based on the dynamic model collocation method of the protective relaying device stipulations of XML, described the dynamic model of protective relaying device stipulations by the self-defined element of XML language, generate dynamic model XML file; Dynamic load, parsing dynamic model XML file when being run by application program, it is achieved the decoupling of application program and configuration specification. And be no longer that reduction rule is solidificated in the middle of program, it is achieved that cross-platform, as long as support the platform of XML technology, the present invention is all applicable. Realize the configuration of stipulations dynamic, rather than be solidificated in the middle of program; Reducing the difficulty of configuration, it is possible to allow research and development, technical support, engineering staff etc. can Fast Learning use. Accomplish real quick response.
Wherein, protective relaying device stipulations generally comprise multilamellar object hierarchy structure; function as included below in device and plug-in unit, function and comprise again the object of other low-level below plug-in unit respectively, this hierarchical structure and object definition are the modellings of a kind of high abstraction to protective relaying device. And dynamic model XML file is exactly based on XML language and the hierarchical structure of this for protective relaying device high abstraction and object definition is converted to hierarchical structure and the object definition of XML, specifically includes following steps:
Step 101, setting up and enumerate data, simple object and composite object model in protective relaying device stipulations, wherein, enumerating data is the constant structure being made up of base data type such as one group of character string, shaping, Boolean quantities; Simple object is the base data type objects such as character string, shaping, Boolean quantity; Composite object then comprises two kinds: the first is the level composite object in protective relaying device, and the second is public composite object, and wherein, public composite object is not mapped to protective relaying device hierarchical relationship.
Step 102, set up object hierarchical relationship each other in protective relaying device.
Definition Attribute is attributes object, and defines the XML attribute ID unique mark as element place level; Public composite object is comprised by defining Element label; Comprise level composite object by defining SubElement label, set up the hierarchical relationship between level composite object by SubElement. As it is shown in figure 1, the hierarchical relationship between hierarchical object is through what SubElement in layer set up, by the attaching relation that this set is abstract, it is established that the model structure of complete set electromechanical protection device.
When the present invention is run by application program, dynamic load resolves dynamic model XML file, it is achieved application program and configuration specification decoupling, and is no longer that reduction rule is solidificated in the middle of program, as in figure 2 it is shown, specifically include following steps:
When step 201, application program launching, the dynamic model XML file that search has configured, and by parsing module, stipulations content entrained inside dynamic model XML file is loaded in program;
Stipulations in application program are not fixing, but are controlled by dynamic model XML file completely, if dynamic model XML file changes, the stipulations that same program loads also change therewith.
Step 202, application program go to resolve corresponding project file according to the dynamic model stipulations of oneself inside, after successfully resolved, the content of project file are loaded into application program;
The content that step 203, application program control inside project file according to the specific object inside dynamic model is shown in which way. Such as, by defining label<OnlyRead>for representing that whether present apparatus object is read-only; Represent that present apparatus object can the minimax number of times of instantiation by defining label<MinOccurs>and<MaxOccurs>; It is used for representing that present apparatus object is the need of display by defining label<Show>; It is used for representing the content that present apparatus object needs show by defining label<ShowInfo>.
Present invention achieves cross-platform, as long as support the platform of XML technology, it is possible to use the present invention, as shown in Figure 3. The system platform of current main-stream such as Windows, Linux etc. support XML technology, so the present invention can use on these platforms. The programming language of current main-stream, all supports XML technology such as Java, C++, QT, C# etc., the present invention can with these programming languages with the use of.
Owing to dynamic model XML is another embodiment of stipulations, so project file content format dynamically generates according to dynamic model, dynamic model is equivalent to the template of project file, and project file is then the instantiation of dynamic model. Additionally by the attribute configuration (whether show, whether must fill out) of dynamic model XML, and then determine how program interface shows the particular content of project file.
Dynamic model XML file is really a kind of protective relaying device stipulations adopting XML language to describe; its collocation method is simple; configuration tool can be used extremely many; without specialty translation and compiling environment; and dynamic model achieves the decoupling of device stipulations and application program, it is a kind of high cohesion, lower coupling, expansible, cross-platform development mode. Based on above reason, the present invention can greatly improve efficiency of research and development, engineering mode efficiency and technical support efficiency, well reduces time cost, learning cost and human cost.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner includes in the scope of patent protection of the present invention.
