In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic flow sheet of a kind of specific embodiment of the grid equipment method for evaluating state of a kind of novelty of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The grid equipment method for evaluating state of a kind of novelty as shown in Figure 1 comprises: make up appraisal of equipment detailed rules and regulations and evaluation algorithms, make up evaluation algorithms administrative mechanism flexibly, make up and have the device class tree of estimating detailed rules and regulations, by estimating detailed rules and regulations equipment estimated.
(1), make up appraisal of equipment detailed rules and regulations and evaluation algorithms, estimate detailed rules and regulations and mainly adopt typical fault tree-model analytic approach design assessment item and content.Estimate to comprise in the detailed rules and regulations and estimate classification, quantity of state, basis for estimation, weight and basic deduction of points.Concrete evaluation detailed rules and regulations such as following table:
The data of this table are that the part of oil-filled transformer is estimated detailed rules and regulations, the structural entity of estimating detailed rules and regulations is tree structure, the child node of structure is the equipment state amount, and the parent node of equipment state amount is minimum valuator device classification, and the quantity of state parent does not have multistage formation in practice.The information that makes up under child node is the evaluation foundation of one-to-many.Analysis by structure draws the building mode of estimating detailed rules and regulations: make up and estimate the detailed rules and regulations classification tree, make up and estimate the detailed rules and regulations judgment basis.The child node of classification tree is carried out related with basis for estimation.
In estimating detailed rules and regulations, need to realize two kinds of algorithms: evaluation content scoring algorithm, scoring item (estimating classification) evaluation result computational algorithm.
The evaluation content scoring algorithm: the function that this algorithm need be realized is the evaluation score that calculates concrete quantity of state, and the computing formula of evaluation score is: weight coefficient * basic deduction of points.Weight coefficient and basic deduction of points are decided by basis for estimation, so the major function of algorithm is for judging which kind of basis for estimation quantity of state adopts.In simple evaluation algorithms, the mode of realization is by artificial selection basis for estimation, i.e. manual evaluation algorithm.
The automatic Evaluation algorithm: in the automatic Evaluation process, algorithm need judge that automatically which kind of basis for estimation is used by the fault data of equipment.The data of fault are the fault text description, and the judgment mode that adopts for this fault data source finally obtains the basis for estimation that adopt for being that the regular expression search key carries out matching judgment in the fault text description with the basis for estimation estimated in the detailed rules and regulations.The accuracy rate of this kind evaluation method can not reach 100%, needs artificial affirmation to judge whether rationally at last.
Though in the automatic Evaluation algorithm, can realize the robotization estimated, but the accuracy rate of estimating is not high, so senior evaluation algorithms is realized by semi-automatic evaluation algorithms, concrete realization thinking is: the state evaluation system openly gives the equipment failure detection system evaluation detailed rules and regulations of equipment by the web service manner, directly in fault detect, just directly the basis for estimation of equipment state amount is determined by the third party system, afterwards basis for estimation is passed back to the evaluation management system and get final product.So just can realize the Real-Time Evaluation of equipment state, and guarantee the validity of evaluation result.So the evaluation content scoring algorithm is divided into: manual evaluation algorithm, automatic Evaluation algorithm, semi-automatic evaluation algorithms.
Scoring item (estimating classification) evaluation result computational algorithm: the realization purpose of this kind algorithm is for drawing the evaluation result of scoring item by the evaluation score of judging each quantity of state.Such as the last evaluation result that draws " body tour ".The foundation that this algorithm is realized is the scoring item evaluation deduction of points table of comparisons.The concrete table of comparisons is as follows:
This algorithm calculates the state of parts automatically by the deduction of points item logical operation method of identifying four kinds of states.The algorithm specific implementation is to realize judging and can realize by the switch case statement, and this algorithm is realized once can not needing to dynamically update.
(2), make up evaluation algorithms administrative mechanism flexibly, in state evaluation, need the algorithm managed total be divided into two kinds: quantity of state evaluation algorithms, scoring item evaluation algorithms.The realization thinking of these two kinds of algorithms has been set forth clear in step 1.Want the unified management of implementation algorithm, the present invention adopts unified evaluation interface to realize management.
All evaluation algorithms are all realized unified algorithm interface, estimate to call and all pass through this interface interchange.All algorithms are all unified to be carried in the algorithm container, and the algorithm container is in the key-value pair Hash Object table of answering, container after system starts with all implementation algorithms under the automatic search catalog, and by reflection acquisition algorithm example and be loaded in the container.The state of algorithm container can be realized management equally in system's operational process, heat loading (not needing delivery system again) that so both can implementation algorithm.
It is related with specific algorithm by the numbering of algorithm to estimate detailed rules and regulations, in the time of needs assessment, to take out algorithm after finding from container and realize class by quantity of state numbering or the automatic numbering of seeking related algorithm of classification of estimating detailed rules and regulations, call by unified interface then and can realize estimating.
(3), make up and to have the device class tree of estimating detailed rules and regulations, by the appraisal of equipment detailed rules and regulations that made up in the step 1 and estimate algorithm in the detailed rules and regulations, equipment need use corresponding evaluation detailed rules and regulations also to need equipment and evaluation detailed rules and regulations are related could realize.The present invention is not with equipment and the direct correlation of evaluation detailed rules and regulations.But adopt device class associate device evaluation detailed rules and regulations, device association device class to realize.Realization equipment has reduced many related job amounts to the automatic coupling of appraisal of equipment detailed rules and regulations like this, also uses the coupling of equipment and evaluation detailed rules and regulations more flexible simultaneously.The evaluation procedure that realizes such as transformer A is: find the evaluation detailed rules and regulations of transformer by the affiliated classification " oil-filled transformer " of transformer A, estimate by estimating detailed rules and regulations then, at last the result is returned to transformer A and get final product.
Device class is estimated classification and is estimated in the detailed rules and regulations classification with related being based upon of estimating detailed rules and regulations, producing related ID is device class ID and evaluation detailed rules and regulations classification ID, be that catalogue can be related with root directory or the sub-directory of estimating detailed rules and regulations, so both can also can estimate by the subclassification detailed rules and regulations by the evaluation of whole big evaluation classification detailed rules and regulations, make more flexible that the appraisal of equipment mode becomes.
(4), begin equipment is estimated, the detailed process of evaluation is:
(1), finds the evaluation detailed rules and regulations of equipment by device class;
(2), the quantity of state basis for estimation in the detailed rules and regulations is estimated in selection;
(3), call the quantity of state evaluation algorithms and draw quantity of state evaluation score;
(4), call the scoring item evaluation algorithms and draw scoring item evaluation state;
(5), obtain the most serious result in all scoring item evaluation results in the evaluation detailed rules and regulations;
(6), with the most serious result in the scoring item as equipment overall evaluation result.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
