Step 2: utilize data processing module to carry out Data Analysis: described intelligent test system obtains the MMS message of device being tested by the network port, the LD list of device being tested is opened in data processing module, input LD to be tested is required according to user test, by the intelligently parsing data submodule in data processing module the MMS message analysis of described device being tested is converted into the information under LD to be tested, by the dictionary file in data processing module, information analysis under LD to be tested is described as the authority data information of the LD to be tested of intelligent test system definition by inquiry submodule and dictionary reading submodule, be converted into the authority data information of unified LD to be tested by the Chinese of different expression form by the information under LD to be tested,
Described LD to be tested is a logical device to be measured of device being tested;
The MMS message of described device being tested is a string code needing to resolve, and the MMS message of the described device being tested of each producer has producer's otherness, needs to carry out intelligent data parsing, and forms unified and standard data;
Information under described LD to be tested is that a string Chinese describes, and the difference of each producer is that the Chinese of same device being tested describes form of expression difference;
The authority data information of described LD to be tested is self-defining, unique, and user is familiar with understandable Chinese definition, and the information under the LD described to be tested of different manufacturers is carried out unified definition;
Step 3: start test.
Described data processing module comprises by data relationship table corresponding to the authority data information of the information under described LD to be tested and described LD to be tested, described data relationship table is a dictionary file, and described dictionary file comprises the semantic basic dictionary submodule of LN and DO and LN and DO semantic extension dictionary submodule; Described data processing module comprises following functions module:
The semantic basic dictionary submodule of LN and DO: because the formulation of IEC61850 specification is issued, the MMS message specification of each producer is unanimous on the whole, sets up a basic dictionary submodule, resolves most of data; The semantic basic dictionary submodule of described LN and DO adopts XML file form, sets up the description document of various LN and various DO;
LN and DO semantic extension dictionary submodule: the difference of each producer is mainly at the form of MMS message, order and specifically define difference, user oneself writes described LN and DO semantic extension dictionary submodule or utilizes extension dictionary generator program to produce described LN and DO semantic extension dictionary submodule, described LN and DO semantic extension dictionary submodule associates with the device being tested of each producer, such as the extension dictionary file of southern auspicious science and technology or the extension dictionary file in four directions, Beijing, when user runs into new device being tested data, by self-defined or amendment, generate new LN and DO semantic extension dictionary file,
Inquiry submodule: support the retrieval of various LD to be tested, inquiry;
Intelligently parsing data submodule: the MMS message data of described device being tested is analyzed, obtain the information under LD to be tested, described intelligently parsing data submodule reads dictionary file according to different devices being tested, obtaining data relationship table, is the authority data information of intelligent test system definition the convert information under LD to be tested according to data relationship table;
Dictionary reading submodule: read above-mentioned authority data information and test.
Described authority data information comprises setting valve parameter and communications parameter.
Described device being tested comprises protective device.
This method solves each producer variability issues by dictionary file, intelligently parsing data.There is different representations in the information of same data in the authority data information of LD to be tested under the LD to be tested of different manufacturers, its one_to_one corresponding, a form will be formed in dictionary file.
Intelligent test system is according to the unified and standard data of successfully resolved, and can obtain the specifying information of the process layer data generated, such as definite value parameter etc., just can production process layer data test automatically.
General Analytical data are directly resolved by program, when resolved data variation, must change analysis program; And this method have employed dictionary file mode, resolution data carrys out intellectual analysis according to the content of dictionary file, and analysis program has nothing to do, and when resolved data variation, just can adapt to new change by LN and DO semantic extension dictionary file.Such system just can not stop to adapt to new intelligent apparatus and new producer's test request by extension dictionary file, and master routine of need not upgrading.
A kind of substation field test intelligently parsing data method provided by the invention applies data processing module, this data processing module has versatility and " self study " function, enable the various devices being tested of intelligent test system on-the-spot test different manufacturers, and whole on-the-spot test process is controlled by data processing module completely, without the need to manual intervention, the test error greatly reducing on-the-spot test workload like this and bring due to human factor.
