The fault that judges described automatic power-measuring terminal to be detected with and corresponding fault type, can judge according to the failure criterion setting in advance, for example drop on the predetermined threshold value interval of a certain fault type in described failure criterion in the value of a certain detected parameters, can judge that described automatic power-measuring terminal has the fault of respective type.
As a kind of preferred implementation, carrying out after detection method of the present invention, can calculate according to default formula the health status score of automatic power-measuring terminal described in each detection according to testing result.Then the same automatic power-measuring terminal of factory's manufacturer production is throughout one's life added up, the final weighting of automatic power-measuring terminal that obtains the production of each manufacturer divides (Weighted Rank-WR), as the evaluation of the automatic power-measuring terminal that described manufacturer is produced.
What intelligent scoring part adopted is the algorithm of Bayesian statistics, the weighting that the automatic power-measuring terminal of each automatic power-measuring terminal manufacturer finally can draw divides (Weighted Rank-WR), and Bayesian formula is very successful on comprehensive prior imformation and sampling information.The weighting that the automatic power-measuring terminal of each automatic power-measuring terminal manufacturer finally can draw divides (Weighted Rank-WR), and formula is as follows:
weighted?rank(WR)=(t÷(t+m))×R+(m÷(t+m))×S
Wherein: the score that R is common detection; T is the number of times that participates in test; M is minimum test statistics number of times, is conventionally set to 3; S is the average of current all detections.
By intelligent scoring function, system can calculate the comprehensive grading of certain terminal, the aspects such as running status to automatic power-measuring terminal, communication, performance, quality play one comprehensive, comprehensively evaluate, the type selecting of buying automatic power-measuring terminal has been played to huge help.
The present invention is directed to the requirement that automatic power-measuring terminal detects, in conjunction with experts database administrative skill, Programmable Technology, a kind of new automatic power-measuring terminal detection method is proposed, both there is the function that automatic power-measuring terminal detects, promote on this basis again, collect by problem and processing experience that different detection techniques, detection are run into, carry out unified management, finally realize programmable power metering automation terminal intelligent problem base management detection platform.Major function by experts database administrative section, robotization test section, programming platform part, intelligent scoring part totally four parts form, platform carries out communication and control by communication module and automatic power-measuring terminal.
By the present invention, to develop a whole set of taking the management of problem experts database, programming platform, robotization detection, intelligent scoring etc. as Core Feature, integrate the autonomous detection software of the functions such as data management, testing result judgement, test result processing, for the terminal type selecting of power customer provides huge help, and greatly reduce the failure rate of terminal operating phase, terminal fault was kept off before installing and using, greatly saved social cost and the human cost of power customer.
The robotization that the present invention realizes detects after being provided with terminal fault detection model, by platform automatically according to the step of terminal fault detection model step by step automatically perform detection, by the actual result obtaining and expected result relatively and reach a conclusion, finally conclusion is recorded.Learn wildly from other's strong points, combine the advantage that black box detects, returns the multiple detection methods such as detection, fault-tolerant detection, form own unique detection method, also there is advantage as follows:
(1) more convenient to the recurrence detection of program, greatly improve detection efficiency, shorten and return detection time.
(2) can move more more loaded down with trivial details detections, within the less time, operation is more detects.
(3) can carry out the detection that some manual inspection difficulties maybe can not be carried out.
(4) utilize better resource, by loaded down with trivial details task automation.
(5) consistance and repeatability, the consistance of the content of each result detecting and execution can be protected, thereby reaches the repeatably effect of detection.
(6) reusability, only need to do a small amount of even not making an amendment, and realizes and in different testing processes, uses identical use-case.
(7) shorten time and the cycle detected.

By the present invention, to develop a whole set of taking the management of problem experts database, programming platform, robotization detection, intelligent scoring etc. as Core Feature, integrate the autonomous detection software of the functions such as data management, testing result judgement, test result processing, for the terminal type selecting of power customer provides huge help, and greatly reduce the failure rate of terminal operating phase, terminal fault was kept off before installing and using, greatly saved social cost and the human cost of power customer.
The robotization that the present invention realizes detects after being provided with terminal fault detection model, by platform automatically according to the step of terminal fault detection model step by step automatically perform detection, by the actual result obtaining and expected result relatively and reach a conclusion, finally conclusion is recorded.Learn wildly from other's strong points, combine the advantage that black box detects, returns the multiple detection methods such as detection, fault-tolerant detection, form own unique detection method, also there is advantage as follows:
(1) more convenient to the recurrence detection of program, greatly improve detection efficiency, shorten and return detection time.
(2) can move more more loaded down with trivial details detections, within the less time, operation is more detects.
(3) can carry out the detection that some manual inspection difficulties maybe can not be carried out.
(4) utilize better resource, by loaded down with trivial details task automation.
(5) consistance and repeatability, the consistance of the content of each result detecting and execution can be protected, thereby reaches the repeatably effect of detection.
(6) reusability, only need to do a small amount of even not making an amendment, and realizes and in different testing processes, uses identical use-case.
(7) shorten time and the cycle detected.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
