Embodiment
The present invention is further described below in conjunction with drawings and Examples.
The application discloses a kind of IEC61850 mass data rapid analysis.The technical solution adopted in the present invention is: by the uniform data management interface, and summary and steady arm are realized the quick traversal of mass data, only by the data terminate-and-stay-resident in preset range analysis, thereby realize the rapid data the analysis no matter much required memories of data volume are fixed, comprise the following steps:
(1) general character of locating, obtaining, analyze according to data is determined unified data management interface.Feature, memory requirement, retrieval to the Various types of data in IEC61850 communication in intelligent substation are located, are obtained and analyze and carried out contrasting and summing up general character, determined the common interface for data management, comprised summarization generation interface, locating interface, obtain interface, analysis interface.Data management interface is by concrete data management back-end realization, support to use several data management rear end, thereby can manage rear end according to the high-performance data of concrete data characteristics design optimization, and improve fast data with existing management rear end and realize fast and deployment newtype data management rear end.
As shown in Figure 1, data management interface 10 of the present invention is that feature, memory requirement, the retrieval of the Various types of data in IEC61850 communication in to intelligent substation located, obtained and analyze and carried out contrasting and summing up general character, determined the common interface for data management, comprised summarization generation interface 11, locating interface 12, obtain interface 13, analysis interface 14.Data management rear end 20 is that of data management interface 10 realizes body, in real system application, a plurality of bodies of realizing can be arranged, and each realizes that body must realize the desired summarization generation 11 of data management interface 10, location 12, obtain 13 and analyze 14.This design, by actual data management rear end 20 and the decoupling zero of rapid data analytical approach, makes data management rear end 20 be easy to improve, expand, dispose, and is conducive to particular type data selection optimized high performance way to manage separately.The data characteristics of 3 kinds of communicate by letter MMS, GOOSE and SV of IEC61850 is widely different, can adopt different data management rear ends.Summarization generation interface 11 generates positional information and data key message by mass data 30 by entry, and is stored as summary 40; Data key message content and form are realized by concrete data management rear end 20, so the data key message of different pieces of information management rear end 20 may be different.The summary 40 that locating interface 12 generates according to summarization generation interface 11 is realized the quick-searching of data key message and is determined corresponding positional information.Obtain interface 13 according to locating interface 12 established data positional informations from the data entry that is retrieved of quick obtaining mass data 30.Analyzing 14 will carry out labor and export analysis result to internal memory by obtaining the 13 data entries of obtaining.
(2) according to data management interface corresponding to step (1), generate the mass data summary.Use the summarization generation interface according to the data key feature, to carry out express-analysis to mass data, generate the summary that comprises key message and Data Position information.The analysis of data key feature and acquisition, by concrete data management back-end realization, as a part of content of summary, are submitted to locating interface by steady arm from the summary storehouse when locator data, then by the data management rear end, specifically processed.
As shown in Figure 1, before carrying out the rapid data analysis, use the summary 40 of summarization generation interface 11 generated datas 30.The 40 disposable generations of making a summary, can, at mass data 30 rapidly locatings, obtain the data acquisition of interface 13 for locating interface 12 while being convenient to analyze.Summarization generation interface 11 should be able to fast processing data 30, and summary 40 data volumes that generate are little.A summary of summary 40 comprises positional information and the data key message of corresponding data entry in data 30, call format: the skew (64 integers) in data 30 forms positional information by data entry number (64 integers), data entry, and the data key message is a maximum 32 byte binary data.Summary info is only done call format, and the implication of specifying information is processed by concrete data management rear end 20, namely makes a summary 40 by 20 generations of data management rear end, when location, imports location 12 into and still by data management rear end 20, is processed.A summary summary of 40 can 30 1 data of corresponding data, corresponding one by one; Article one, summary also can corresponding one piece of data, i.e. the initial entry of many data, one-to-many; One by one at once can disposable accurate location, but it be 40 larger to make a summary; During one-to-many between two summaries fuzzy location, summary is 40 less, especially is applicable to the very large situation of data 30.
(3) according to summary corresponding to step (2), obtain the data in preset range and analyze in location fast by steady arm.Steady arm has recorded the reference position of the current data of analyzing in mass data.The data entry number of preset range for analyzing at internal memory.After steady arm was realized fast moving location according to summary by locating interface, the data of the preset range started from the positioning instant reference position were loaded into internal memory by data acquisition interface, then by the data analysis interface, analyze.
As shown in Figure 1, after summary 40 generates, just can use steady arm 50 to travel through location by locating 12 pairs of data 30.Steady arm 50 has recorded the reference position of the current data of just analyzing in internal memory in data 30, and namely the steady arm position 70.Data 30 are being traveled through to when location, steady arm 50 is obtained corresponding summary entries information from making a summary 40 and is imported location 12 into, and upgrades the steady arm position 70 of steady arm 50 at every turn.The traversal location is two-way, namely can, to the location, front of data 30, also can locate rearwards.Because summary 40 information that provide have been dwindled the traversal orientation range, so even data 30 are very large, the traversal location is also fast; On the other hand, if the summary info accuracy of data management rear end 20 and to locate 12 handling property relatively good, the traversal location can be faster.After steady arm 50 location are determined, just can from data 30, obtain data by obtaining 13, then by analyzing 14, in internal memory, analyze the data of obtaining.The concrete data of analyzing in internal memory are relevant with the steady arm position 70 of steady arm 50.Steady arm position 70 is the reference position of the data analyzed in internal memory, the Data Position in corresponding data 30, and the data that start from this position, be no more than preset range 60 are analyzed internal memory.The maximum data entry number of preset range 60 for analyzing in internal memory at one time, therefore no matter data 30 are much, and when traversal was analyzed, required maximum memory was fixed.Preset range 60 is configurable, and larger use internal memory is larger, but the fluency of analyzing is better.Preset range 60 is also attached a kind of mechanism simultaneously, when analyzing, be no more than preset range 60 in order to control the data entry number of analyzing simultaneously, before having new data to be acquired and preparing to analyze, at first the data of analyzing to be shifted out to 80 parts from internal memory, make remaining data and new data summation be no more than preset range 60.Take steady arm position 70 is benchmark, and in the former data of analyzing in internal memory, away from 80 internal memories that are moved out of of this benchmark, close is moved into 90; Alternate position spike before this benchmark and location is new data, and amount of new data determines, just can determine the data that will shift out and shift out according to preset range 60 and the data volume just analyzed in internal memory, then obtains new data and analyzes in internal memory.
(4) by mobile locator, realize the analysis to all mass datas.Steady arm moves and while navigating to reposition, data away from reposition in former preset range shift out internal memory, data near reposition move into internal memory, and data volume is no more than preset range all the time, thereby realize, rapid data analysis stable, that low-resource take irrelevant with the data volume size.All data traversals of data 30 are analyzed and worked in coordination with by above-mentioned data management interface 10, data management rear end 20, steady arm 50 and preset range 60.No matter data volume is much, can 40 dwindle the traversal orientation range by making a summary, and namely can travel through fast steady arm position 70 and obtain data; The data volume of analyzing in internal memory at one time is no more than preset range 60, depends on shifting out 80, moving into 90 mechanism of preset range 60, can the control analysis required memory, and also the data of analyzing are the sub-fraction in mass data, and analysis speed is fast.Integrate, method of the present invention has realized being easy to the high-performance data that improves, expands and dispose management, and has realized, rapid data analysis stable, that low-resource take irrelevant with the data volume size.
The embodiment more than provided is in order to illustrate the present invention and its practical application, and therefore make those skilled in the art can realize or use the present invention, or else those of ordinary skills can break away from the situation of invention thought of the present invention, above-described embodiment is made to various modifications or variation, thereby the present invention do not limit by above-described embodiment, and it should be the maximum magnitude that meets the novelty characteristic that claims mention.
