The Chinese patent documents CN109978495A, CN110070871A, CN108536659A, CN106570105A and CN110659289A all describe the current situation that most of the current test data are manually recorded and stored by paper, point out the defects of the test report controlled by adopting the method, and further provide a corresponding solution.
The chinese patent document CN106570105A takes a paper test report as a basis, converts the paper test report into an electronic image file, converts the image file into text information by an OCR technology, and then matches a template to process into an electronic test report. The patent document still does not depart from the problem that manual intervention is too much in the process of issuing a paper test report, the current OCR technology is not perfect, the recognition rate of handwritten texts is not high, and the problem easily occurs in the management and control of the test report especially under the condition that field workers have five-degree-of-five handwritten fonts.
At present, each link of the test major in the power production industry is managed completely by depending on a WEB end and is realized through a test report management system, and the management modes of the test reports in the system are that test report compiling, test report auditing and test report filing are all completed at the WEB end. The test report preparation refers to the steps that a tester determines a plurality of test report templates in a test report management system according to test major, test properties, test equipment types and the like, selects a template corresponding to test equipment according to the test report templates, selects a corresponding test item again according to the test templates, can create a corresponding test report through a plurality of operations such as test major, properties, transformer substations, equipment, templates, items and the like, then records data collected on site and recorded on a paper document into the test report management system one by one, and submits the data to corresponding team groups for auditing after the data are recorded.
The examination and verification of the test report refers to that team personnel search corresponding test standards and test specifications according to the test report submitted by the test personnel and test equipment, examination and verification are carried out on filled test items and corresponding test data one by one, problem data are recorded, the test items are marked as unqualified, the examination and verification can be completed only through examination and verification of a plurality of items and a plurality of items of data, and a special duty is submitted for examination and verification after the examination and verification are completed.
The test report filing means that corresponding test standards and test specifications are searched again according to test equipment according to test reports submitted by team personnel, the filled test items and corresponding test data are checked one by one, unqualified data items are paid attention to again, the checking can be completed through the checking of a plurality of items and a plurality of items of data, comprehensive judgment is carried out according to the current operation condition of the test equipment and the maintenance condition of the test equipment, the next test time or maintenance time of the current equipment is determined, and the test report is filed.
Because the test report has a plurality of templates, data can be input only manually, and the test conclusion can be checked only manually, the test report of the test report management system has the problems of non-uniform test report templates, time and labor waste in data input, lack of intelligent checking, lack of trend analysis and the like.
For this reason, the chinese patent document CNCN110659289A proposes a quality test report management method for material quality detection, which first stores test data to a client and a server, respectively, where the test data includes test raw data and test data provided by a supplier. The original test data are quoted at the client side according to the detection items corresponding to the materials and a test report is generated; and transmitting the generated test report to a server for processing to verify the accuracy of the test report and the accuracy of the detection data provided by the supplier. The core of the method is to avoid the data of the supplier end and the supplier end from being faked and the operation condition of the equipment side from being evaluated.

Detailed Description
Regarding the test equipment of the power system, such as a loop resistance tester, a ground resistance tester, a relay protection tester, a transformation ratio tester, a direct current high voltage generator, a frequency generator, a high voltage switch dynamic characteristic tester and the like, the test equipment for testing each link of the power system is used as an instrument and meter, generally has a port connected with an upper computer, and can directly upload test data.
Some test data can be manually input by field personnel to, for example, a work area client, which can be seen in fig. 1, and in the figure, the work area client serves as a leaf node for acquiring test data of an electric power system to form an upper computer of an acquisition terminal, which is the aforementioned test equipment.
A local area network for acquiring test data is constructed by a plurality of factory clients in a certain factory area, and the local area network can be established on a wired network or a wireless network.
The local area network is connected to the external network through a core network switch, in fig. 1, the province company client forms a father node of the information internal network, and the province company client can be used as an approval end and used for monitoring test data of subordinate nodes of the province company client.
In the network constructed in fig. 1, the data server and the application server may be deployed at a lower hierarchy level, or may be deployed at a higher hierarchy level. When the system is deployed at a lower level, the number of required servers is large, and a server cluster can be constructed.
For higher levels, the test data of all the areas are collected, and the statistical characteristics of the test data are more representative.
The test data can be directly collected by the test equipment and then uploaded, and in more applications, the field equipment is provided with instruments, such as current measuring equipment, voltage measuring equipment and the like. In more applications, based on a centralized and distributed field working condition acquisition system, a monitoring system based on force control software is arranged at a power plant end, and the monitoring system can be used as a work area client.
The terminals located at higher levels in the topology shown in fig. 1 are preferably configured for BI-based experimental data analysis, presentation. Where BI is an abbreviation of Business Intelligence, Business Intelligence. Also known as business intelligence or business intelligence, refers to the realization of business value by data analysis using modern data warehouse technology, on-line analysis processing technology, data mining and data presentation technology. The concept of business intelligence was first introduced by the Gartner Group (Gartner Group) in 1996.
By adopting BI, the dimension data analysis of the test report can be realized, multiple dimensions such as date, property, profession and the like can be defined, free combination and configuration can be performed, test items and test data corresponding to the test report under different conditions can be freely displayed, and two viewing modes of a report form or a chart are supported.
For example, the chart has intuitive comparison of historical test data or sampling data of different test devices in the same time period, and is beneficial to making correct evaluation on the test data.
The method comprises the steps of adopting BI to analyze equipment dimension data, defining through multiple dimensions such as a power station, test equipment, equipment manufacturers, equipment models, equipment types and test dates, freely combining and configuring, inquiring corresponding equipment and test report data, analyzing test data of different manufacturers, models and different test items, displaying test items, phases, parts, test sub-items and the like of selected equipment under corresponding test templates, carrying out rapid contrastive analysis, and supporting two viewing modes of reports or charts.
Intelligently analyzing data, automatically analyzing report contents, verifying the normalization of test values, and reminding abnormal values; automatically checking a test value and a test result; and data trend analysis is provided, and when the data tend to be degraded, the system automatically checks and gives a prompt.
With respect to the test reports, known test reports lack the necessary regulations and the test report templates differ from region to region. Correspondingly, when the test data is additionally recorded, corresponding test templates need to be selected according to equipment, and the template names are basically similar and difficult to distinguish. Part of the test template was missing. The test, the example inspection and the first inspection before commissioning are all nonstandard and have no corresponding test template, and test data is easy to lose in a paper document.
In the embodiment of the invention, on one hand, the test report template adopts an electronic document, and data is directly imported by test equipment based on field matching to generate a corresponding test report. It will be appreciated that the test devices may be identified by their ID or by a physical ID based on the national grid, so that relevant data may be deposited for indexing by, for example, physical ID, and relevant test reports identified.
As mentioned above, some power plants, for example, have already established a relatively complete monitoring network, and use it as a work area client or use the monitoring terminal included therein as a work area client to construct a test data acquisition system. The test data can be directly obtained by the client side of the work area.
In addition, the conventional problem of manually inputting test data is mainly that the amount of test data is very large, tests of different test specialties of each device need to be input for many times, and even obvious errors in inputting are not explicitly displayed. For some data that is significantly overrun, it may be judged and reminded based on the logging threshold.
The test report template can be generated from the uppermost layer of the test data acquisition system and distributed downwards, and the test data is directly imported into the test report template to generate a test report.
In some embodiments, the generation of the test report is not limited to a certain node, for example, at a certain layer of node, the relevant person may click on the relevant test equipment, extract the relevant test data, and directly export the relevant test data to the corresponding test report template to generate the test report.
At present, because the rationality of the test value can not be judged when the test data is input, relevant standards and specifications need to be checked, and the process can be filed only by examining and verifying a plurality of personnel for a plurality of times.
In the embodiment of the invention, the range of the equipment working parameters determined by the relevant standards and specifications is recorded into the data acquisition system, so that the reasonability of the recorded data is controlled, and the limitation of manual work and manual error investigation is reduced.
The range of the working parameters can be set according to initial value data provided by a manufacturer or an expected data range, so that test data in a test report can be checked according to the initial value data and a preset corresponding test threshold to generate a judgment result.
More specifically, according to the test correspondence of the target device, the relevant standard and the standard regulation are determined, the judgment rule is compiled, the judgment rule is stored in the rule base, and when the relevant test data is checked, the rule corresponding to the test data is called from the rule base to check the test result determined by the test data.
In some embodiments, the relevant judgment rules are compiled according to, for example, national regulations, factory regulations, standard regulations, such as different voltage levels, equipment types, test specials, test properties, test items, phases, test sites, test sub-items, etc., as follows:
according to the table, whether the content of hydrogen is over standard or not is determined, a rule is formed and stored in a rule base, when data of routine inspection of dissolved gas in casing oil is checked, a rule requesting an analysis item of the dissolved gas in the casing oil of the 220Kv main transformer is called to judge whether the test data is qualified or not, wherein the qualified data is not the data per se, but whether the electrical equipment meets the relevant rule or not. And finally, generating a judgment result, and sending the judgment result and the test report to the previous layer.
In general, for each test sub-item, there is a rule configured for it, and when the test sub-item of the electrical device needs to be tested, the corresponding rule in the rule base is called to audit the obtained test data.
And further, the judgment result or conclusion is sent to the approval end of the test report, and the related test report is simultaneously reported so as to facilitate the inspection and the total storage at the approval end.
In addition, the data stored in the total can be further transmitted to the upper layer or called by other approval ends.
Furthermore, the approval end gives a system judgment conclusion, so that the approval end can conveniently check the test result.
In addition, in some embodiments, after the test report is compiled, the test report can be submitted to an auditing link in advance, and the pre-inspection can be performed in the auditing link in advance, and can be performed manually.
Furthermore, when the test report is submitted to the pre-inspection of the auditing link, the test report can also be automatically submitted to the rule background, the rule background automatically judges the data in the report according to the preset rule, and when the auditing link is submitted to the approval end, the judgment result is pushed to the approval end.
For the test data acquisition system of the power system shown in fig. 1, the upper node controls the distribution of the test report template adapted to the lower node, and obviously, based on the tree network topology structure, the upper node is relatively necessary to serve as an approval end of the higher node to unify the relevant test report templates. Specifically, for a given test report item, a normalized test report template is employed.
It should be noted that the test report does not necessarily need to be submitted to the node at the highest level, and when a specific test report at an intermediate level is returned, the specific test report needs to be submitted to a certain node corresponding to the intermediate level, and the test report template is also generated and distributed by the node.
The original test report template and the newly added test report template are different from each other, data analysis cannot be directly carried out on the original test report template and the newly added test report template, a historical test report migration method is provided, the original test report data are migrated to the new template through registration of corresponding test items by means of certainty of the test data rather than diversity of formats of the test reports, the new test reports are automatically generated in batches, and data are guaranteed to be unified template data, so that data analysis is carried out on the aspect. Generally speaking, for historical test reports, test data in the historical test reports are migrated to the current test report template, and new historical test reports are generated.
The data of the same electrical equipment at different time intervals can fluctuate, and the fluctuation is the fluctuation on the existing operation rule, but not the fluctuation range of the operation rule. The statistical characteristics of the data can predict the risk of equipment failure, and for this reason, the approval end further generates a transverse judgment result, and the transverse judgment result is obtained by comparing the current data of the current test equipment with corresponding historical data.
And generating a change curve or a change trend report by the current data and the historical data, and outputting a prompt when the change curve is degraded based on a preset change threshold.
Aiming at different equipment of the same equipment manufacturer or the same model, longitudinal comparison of corresponding test data is carried out, current statistical data of the different equipment of the corresponding equipment manufacturer or the same model are generated, and a statistical rule is formed;
and screening out test data which do not accord with the statistical rule based on the statistical rule, and outputting a prompt.
The comparison and analysis, transverse and longitudinal comparison and auxiliary analysis of the running condition of the equipment of the test data are realized, so that the workload of the basic team is reduced, the data quality of the test report is improved, the application level of the test report is improved, and the monitoring capability of the equipment is enhanced.
For the storage of test data, firstly, the generation of the test data has obvious temporal characteristics, and then the generation of the test data is the source characteristics of the test data, and the two basic characteristics can effectively ensure the accuracy of the test data management.
In some embodiments, different devices of the same model are associated with the same model and defined with different device numbers, forming secondary data indexed by model and device number.
In some embodiments, the test equipment and/or work area client temporarily stores test data;
and the temporary storage test data is imported by the wholesale end, the work area client or the intermediate node between the approval end and the work area client in response to the external instruction of the selected corresponding test equipment, so as to generate a corresponding test report.
Based on the embodiment of the invention, the test template is perfected by combining the actual service on site according to the system management requirement, the data is normalized, the management burden brought by a large number of similar templates is reduced, and the working efficiency can be improved by adding missing test templates through upper nodes and pushing the test templates downwards.
According to the business needs, the judgment result is formed by judging the background rule, so that the automatic verification of the test report data is added in the auditing and filing links, the records which are not in the test data range are marked, the auditor is reminded to pay key attention, a standardized flow system is built, and the test data quality is guaranteed.
In addition, through the direct import of test equipment, test report data can be entered fast, has guaranteed the integrality of data, provides the support for the analysis of test data, and test data accessible test report dimension and test equipment dimension carry out trend analysis, develop intelligent analysis according to different aspects such as test item, sub-item, producer, model, and the quick analysis goes out equipment behavior, promotes intelligent level.
