Abstract
The invention discloses an ICD (IED Capability Description) inspection method based on objectified module semantics. The ICD method based on the objectified module semantics comprises the following steps bearing all data modules through standard RDF (Resource Description Framework) Schema modules; objectifying the RDF standard modules; setting nodes in a document as RDF data objects and setting relations between objects; performing semantics inspection of every node according to the standard RDF Scheme modules and obtaining an inspection report. Under the condition that ICD documents are changed frequently, the ICD inspection method based on the objectified module semantics has the advantages of saving labor cost, improving working efficiency, reducing repeated work and effectively solving the cooperation problems between different equipment manufacturers due to different standard understanding.
Description
Technical field
The present invention relates to a kind of ICD method of inspection based on the model object semanteme.
Background technology
In the intelligent substation process of construction, the ICD file is serving as important role, the ICD file offers system integrator by device manufacturer, system integrator carries out integrated according to the signal that defines in the ICD file again, the ICD file is the bridge of each link of contact, wherein describes the communication capacity of device in detail.But at present intelligent substation construction is faced with following problem:
1. the establishment of ICD file is carried out in the configuration tool of writing oneself of each equipment manufacturers, and correctness is difficult to guarantee.
2. the ICD document change that provides of each equipment manufacturers is frequent, and does not have strict Version Control mechanism.
3. each equipment manufacturers does not carry out the definition of signal in strict accordance with the IEC61850 standard when creating the ICD file.
4. Chang Yin is different and produce matching problem to the understanding of standard between each equipment manufacturers.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and a kind of ICD method of inspection based on the model object semanteme is provided, and it has the verification difficult problem advantage that solves each node dependence correctness in the ICD file.
To achieve these goals, the present invention adopts following technical scheme:
The ICD method of inspection based on the model object semanteme mainly may further comprise the steps:
Step (1): the RDF Schema model of setting up the ICD file according to IEC61850 standard Schema model (XML Schema), the reason of setting up corresponding RDF Schema model is to exist close dependence between the node in the ICD file, is fit to carry with object-oriented data model; Described RDF Schema model is the model RDF Schema that Chinese patent (application number: 201110227408.9, patent name is: the figure and the rdf model construction method that are used for the intelligent substation design) the inside is mentioned;
Step (2): RDF Schema model object; All ICD Archive sits are created as OO RDF data object example, it is related that dependence between all ICD Archive sits also is created as concrete RDF data object, and all nodes will store into the form of RDF data object in the object-oriented data model in the final ICD file;
Step (3): node is resolved; If Existence dependency relationship not between the ICD Archive sit, semantic verification will be directly and the standard rule base that establishes according to the specific data limit definition of the IEC61850 in advance verification of comparing; And if Existence dependency relationship between the ICD Archive sit, storage and RDF data object example this ICD Archive sit Existence dependency relationship in the step (2) are just taken out in semantic verification, carry out the analysis-by-synthesis verification in conjunction with defining the standard rule base that establishes according to the specific data limit of IEC61850 in advance;
Step (4): obtain the verification report.
The analysis-by-synthesis verification of described step (3) be according in the standard rule base to the restriction of data, quote validation verification, what is called is quoted the coupling that validity is logic node and logical node type in the ICD file.The analysis-by-synthesis verification of described step (3) and the difference of Inspection are that the analysis-by-synthesis verification not only will carry out the verification of ICD Archive sit, also need the dependence between the ICD Archive sit is carried out verification.
The semantic verification of described step (3) is divided into following steps:
Step (3-1): set up corresponding RDF Schema model according to IEC61850 standard Schema model (XML Schema);
Step (3-2): resolve the ICD Archive sit, create simultaneously the RDF data object example of ICD Archive sit and store in the OO RDF data model, dependence between the ICD Archive sit is also stored in the OO RDF data model with the form of RDF data object, in the RDF data model, will store whole ICD Archive sit information by OO structure like this;
Step (3-3): if Existence dependency relationship not between the ICD Archive sit, with directly with the standard rule base Inspection that establishes in advance; The verification if Existence dependency relationship between the ICD Archive sit, the RDF data object that just taking-up needs from the RDF data model are compared.
The RDF Schema model object of described step (2) is to adopt the form identical with IEC61850 standard Schema model, describes IEC61850 standard Schema model with RDF, provides the RDF Schema of IEC61850 standard Schema model; Node intelligent device IED, accessing points AccessPoint, logical device LDevice, logic node LN among the SCL are mapped as respectively intelligent apparatus IED model class, accessing points AccessPoint model class, logical device LDevice model class, the logic node LN model class of RDF;
Described ICD file including model self-described information, by DOI element, the data object example DOI of engineering distant view scale profile instance; " desc " that described data object example DOI comprises Chinese describes and the intelligent apparatus important informations such as dU attribute assignment and manufacturer (manufacturer), model (type), configuration version (configVersion), empty signal definition; for guarantee that the ICD file that changes iteration meets standard criterion at every turn; to reduce owing to the grammer of ICD file or the repeated work that semantic error brings, should carry out according to the ICD model file that IEC61850 standard and IEC61850 " engineering relay protection application model " standard provide producer the verification of grammer, semanteme.
XML(Extensible Markup Language): extend markup language.
ICD(IED Capability Description): IED ability description file.
SCL(Substation Configuration Description Language): the substation configuration description language.
XML Schema: the legal structure module of definition XML document.
RDF (Resource Description Framework): RDF is that the XML of a process metadata uses, and so-called metadata is exactly " data of data of description " or " information of descriptor ".
RDF Schema:RDF Schema itself also is a RDF file, is the definition to the RDF type.
Beneficial effect of the present invention: than in the situation more frequently, can effectively save human cost at the ICD document change, increase work efficiency, reduce repeated labor; Effectively solved between each equipment manufacturers and understood the different matching problems that produce because of standard.
