Or any one of JMS service is uploaded to data center systems.
Preferably, in step 3, real time data derived from data center systems is the specification E format with unique identification ID
Text data.
Preferably, metric data includes telemetry and remote signalling data.
Preferably, the timing cycle of source timing publication E format text data is adjustable, the length and verification of timing cycle
As a result related.
Compared with prior art, the present invention having the advantage that
1, the present invention is based on metric data and measurement model self organizing maps mechanism, take E format text group organization data, shape
Be conducive to data check at static data text, compared to traditional specification binary system description, E format stationery has efficient, easy-to-use spy
Property；
2, the present invention takes automatic data-check, eliminates a large amount of desk checking work, has saved cost of labor, avoided
Because desk checking notes abnormalities the hysteresis quality of data.
Detailed description of the invention
Fig. 1 is the flow diagram of the method for the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the present invention, technical solution of the present invention is clearly and completely described, it is clear that
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, those of ordinary skill in the art's all other embodiment obtained under the conditions of not making creative work belong to
The scope of protection of the invention.
As shown in Figure 1, the present invention provides a kind of Distributed Modeling System metric data method of calibration based on E format,
Electrical power system metric data is verified on the basis of model interaction, the described method comprises the following steps:
Step 1, the unique ID of the data of source system and data center systems is determined.Metric data includes telemetry
And remote signalling data.
Step 2, source timing issues the specification E format text data with unique identification ID, and by the E format of publication
Text data is uploaded to data center systems.Source timing issues the specification E format text data with unique identification ID
Timing cycle can adjust according to actual needs, and the length of timing cycle influences the timeliness of check results, and the period the short more can
It notes abnormalities in time, suspicious data.
Data source systems pass through the E format text data of publication in SFTP service, WebService service or JMS service
Any one be uploaded to data center systems.E format text data describe an amount using " mark-value-measuring quality code "
Measured data, wherein " mark " is carried out as " rdf:ID " for measuring object in the uniqueness mark and CIM measurement model of data
Mapping.
Specifically, data format refers to " E language format ", while considering the analyzing efficiency of E format, and E Format Type is real
The attribute number of body reduces to the greatest extent, and telemetry is marked with AnalogValue, according to mark-value-measuring quality code, that is, ID-
Value-Quality exchanges telemetry, and remote signalling data is marked with DiscreteValue, according to mark-state-state
Quality Codes, that is, ID-Status-Quality exchanges remote signalling data；The value of identity property ID need to be corresponded in CIM model and be measured
The rdf:ID attribute value of Measurement, so as to by the measurement record matching in measuring value and system；The Quality Codes of two major classes
Quality is that 1 expression is effective, and 0 indicates invalid, and the state Status of remote signalling is that 1 expression is closed, and 0 indicates to divide.
Data header is marked using system, and content includes identified areas (Area), data time (Time).Region
(Area) the region english abbreviation for indicating generation data, to distinguish each data source systems；Data time (Time) with
The expression of " 2018-08-22T15:00:00 " format is accurate to the second.
Example is as follows:
