Method and system for determining fault root cause and computer readable storage medium

The embodiment of the invention discloses a method and a system for determining a fault root cause and a computer readable storage medium. According to the method, fault source information is analyzedfrom the three dimensions of multi-time-sequence correlation, data stream correlation and event correlation, and a first fault index and an anomaly index set are acquired; a Pearson-grey correlationcombination method is utilized to calculate the correlation degree between the first fault index and each anomaly index in the corresponding anomaly index set; the anomaly indexes corresponding to thecorrelation degrees meeting a preset threshold are used as a correlation result set; a pre-established fault diagnosis set is queried, a historical diagnosis result set corresponding to the first fault index is acquired; and an intersection of the correlation result set and the historical diagnosis result set is calculated, and the index contained in the intersection is the fault root cause of the first fault index. According to the technical scheme, automatic and intelligent mining and positioning of the root cause of a fault in an e-commerce system are realized, and the problem solving speed of development, operation and maintenance personnel is effectively increased.

Microquake multi-parameter early warning method of rock burst in high-stress concentration area

The invention discloses a microquake multi-parameter early warning method of a rock burst in a high-stress concentration area. Microquake signals are recorded by use of a microquake monitoring system, and a microseismicity S value, a microseismic time information entropy Qt value, a microquake accumulation impact index E value and a microseismic activity abnormal index |Z| value are calculated and analyzed; after obtained data is analyzed, evolution graphs of the four indexes are respectively drafted; according to the drafted evolution graphs, whether the phenomena occurs in the same time period is analyzed that the microseismicity S value is firstly decreased within seven days and then is rapidly increased at a rate greater than a decreasing rate, the microseismic time information entropy Qt value is continuously decreased within four days, the microquake accumulation impact index E value is greater than a critical value Em and the microseismic activity abnormal index |Z| is greater than three, if the two to four from four indexes occur in the same time period, it is determined that a rock burst is about to take place. According to the invention, an early warning of the impact burst is given in an integrated mode by use of multiple parameter indexes, and thus the early warning accuracy can be effectively improved.

Feature grouping-based electric energy metering abnormality diagnosis method and system

The embodiments of the present invention disclose a feature grouping-based electric energy metering abnormality diagnosis method and system. The invention aims to solve the technical problems of vulnerability of judgment results to subjective effects, lack of theoretical basis and long judgment and identification time which are caused by a condition that judgment on the failure abnormality modes of an electric energy metering device mainly relies on the experience of technicians of field maintenance processing. According to the implementations of the invention, the method includes the following steps that: an initial database is constructed according to obtained electric energy metering abnormality types, judgment criteria of the electric energy metering abnormality types and a corresponding data source; the data of the data source of the initial database is transformed according to the judgment criteria of the electric energy metering abnormality types, so that an initial metering abnormality indicator set is formed; indicator feature grouping is performed on the initial metering abnormality indicator set, so that a plurality of indicator groups are formed; multi-classifier training is performed on the indicator groups, so that a plurality of different classification models can be obtained; and the different classification models are fused, so that an electric energy metering abnormality recognition result can be obtained.

SDN abnormal flow detection method based on re-marking range method

The invention discloses an SDN abnormal flow detection method based on a re-marking range method, and belongs to the technical field of computer network security. The method comprises the following steps: collecting the number of normal network flow packets of each node (including a controller and each user terminal) of the SDN, and respectively calculating the Hurst index of the normal network flow packets; storing and taking as a network normal index, and setting a threshold value of a normal state; collecting the number of network flow packets with certain known exception of each node, andcalculating the Hurst index of each node as the index of the exception; intercepting a forward sequence by using a window function and calculating a Hurst index of the forward sequence, and if a normal index is finally changed into a certain abnormal index, determining that the abnormality of the mode occurs and determining an abnormality occurrence time point. And if only the index change deviates from the normal value, but the similar abnormal index cannot be found, an exception except the known mode occurs, and an exception time point can be determined. According to the method, the flow state can be detected in real time, whether the flow is abnormal is judged, the abnormality occurrence time can be detected, and the security of the SDN network system is enhanced.
