Description

A kind of info web extracts audible and visual alarm method

Technical field

The invention belongs to power information communication technical field, particularly relate to a kind of info web and extract audible and visual alarm method.

Background technology

Power system information automaticity is high, the infosystem of enterprises self O&M just nearly tens, therefore how can the reliable and stable operation in 24 hours of guarantee information system, real-time monitoring, in real time process are crucial steps, but still lack effective info web extraction audible and visual alarm method at present.

Summary of the invention

In order to solve the problem, a kind of info web is the object of the present invention is to provide to extract audible and visual alarm method.

In order to achieve the above object, info web extraction audible and visual alarm method provided by the invention comprises the following step performed in order:

Step 1) determine S101 stage of position, target data area: the core information block of obtaining information system network page information, page info is defined as tree structure, the node of maximum out-degree is had to be root node, data are in the subtree having maximum out-degree node, and determine target data region;

Step 2) data record and extract the S102 stage: after position, data area is determined, the data of webpage to be monitored for infosystem are recorded in determinant form; Then special form processing modules is adopted to carry out data extraction, first obtain the content of form and be stored in corresponding determinant matrix, then the content in matrix is organized into the record of format in the mode of row or column, utilize the example meeting infosystem description formatted record to be converted to the example of system description afterwards, finally example is stored;

Step 3) determine S103 stage of the threshold value of every data in tableau format: each corresponding information point in definition tables structure, to the data analysis that each information point relates to, and determine the alarm threshold of every data;

Step 4) formulate S104 stage of alarm level: formulate alarm level, classification is carried out to the data exceeding threshold value, the alarm that different grades is corresponding different;

Step 5) identification data, inspire the S105 stage of corresponding audible and visual alarm: the final identification data obtained from infosystem webpage to be monitored and respective threshold are compared, if exceed threshold value, inspire corresponding audible and visual alarm.

In step 3) in, in described determination tableau format, the method for the threshold value of every data is:

By drawing the COMPREHENSIVE CALCULATING of the out-of-limit rate of performance, performance importance and equipment importance for describing the alarm threshold of every data of equipment performance, if the out-of-limit rate of performance is Τ, performance importance is Ν, equipment importance is Β, the specific formula for calculation of performance alarm threshold value Α is as follows:

A＝(1+T)·N·B

Wherein the out-of-limit rate Τ of performance calculates according to the deviation of performance threshold and actual value, and performance importance Ν manually sets in performance rule management according to producer and device definition, and equipment importance Β then draws according to following formulae discovery:

$B=\frac{\mathrm{\δ}\·\mathrm{\η}}{{\mathrm{\γ}}^2}\·\frac{{\mathrm{\μ}}^{\′}}{\mathrm{\μ}}$

Wherein γ be equipment total bandwidth, δ for taking total bandwidth, η is higher order path total bandwidth, μ is bearer service quantity, μ ' is carrying important service quantity.

In step 4) in, described alarm level is generally divided into critical alarm, high severity alarm, minor alarm, problem alarm four grades.

Info web provided by the invention extracts the effect of audible and visual alarm method:

Effectively can promote the real-time of monitoring, largely, shorten fault discovery time and fault Deal with Time.

Accompanying drawing explanation

Fig. 1 is that info web provided by the invention extracts audible and visual alarm method flow diagram.

Embodiment

Extract audible and visual alarm method below in conjunction with the drawings and specific embodiments to info web provided by the invention to be described in detail.

It is that the information treating web page monitored carries out analysis and Modling model that info web provided by the invention extracts audible and visual alarm method; According to vision mode, corresponding extracting rule is formulated to info web to be monitored; Information according to extracting establishes corresponding alarm threshold; Alarm level is formulated to out-of-limit data; And the alarm out-of-limit to threshold value inspires audible and visual alarm.

As shown in Figure 1, info web extraction audible and visual alarm method provided by the invention comprises the following step performed in order:

Step 1) determine S101 stage of position, target data area: the core information block of obtaining information system network page information, page info is defined as tree structure, the node of maximum out-degree is had to be root node, data are in the subtree having maximum out-degree node, and determine target data region;

Step 2) data record and extract the S102 stage: after position, data area is determined, the data of webpage to be monitored for infosystem are recorded in determinant form; Then special form processing modules is adopted to carry out data extraction, first obtain the content of form and be stored in corresponding determinant matrix, then the content in matrix is organized into the record of format in the mode of row or column, utilize the example meeting infosystem description formatted record to be converted to the example of system description afterwards, finally example is stored;

Step 3) determine S103 stage of the threshold value of every data in tableau format: each corresponding information point in definition tables structure, to the data analysis that each information point relates to, and determine the alarm threshold of every data;

By drawing, as the quantitative criteria of alarm classification the COMPREHENSIVE CALCULATING of the out-of-limit rate of performance, performance importance and equipment importance for describing the alarm threshold of every data of equipment performance.If the out-of-limit rate of performance is Τ, performance importance is Ν, equipment importance is Β, the specific formula for calculation of performance alarm threshold value Α is as follows:

A＝(1+T）·N·B

Wherein the out-of-limit rate Τ of performance calculates according to the deviation of performance threshold and actual value, and performance importance Ν manually sets in performance rule management according to producer and device definition, and equipment importance Β then draws according to following formulae discovery:

$B=\frac{\mathrm{\δ}\·\mathrm{\η}}{{\mathrm{\γ}}^2}\·\frac{{\mathrm{\μ}}^{\′}}{\mathrm{\μ}}$

Wherein γ be equipment total bandwidth, δ for taking total bandwidth, η is higher order path total bandwidth, μ is bearer service quantity, μ ' is carrying important service quantity.

Step 4) formulate S104 stage of alarm level: formulate alarm level, classification is carried out to the data exceeding threshold value, the alarm that different grades is corresponding different;

According to step 3) alarm threshold of every data that calculates, carry out classification to alarm, minor alarm rank is divided into critical alarm, high severity alarm, minor alarm, problem alarm four grades.

Step 5) identification data, inspire the S105 stage of corresponding audible and visual alarm: the final identification data obtained from infosystem webpage to be monitored and respective threshold are compared, if exceed threshold value, inspire corresponding audible and visual alarm.

Info web extraction audible and visual alarm method provided by the invention carrys out information extraction for the infosystem webpage of B/S structure, and described info web comprises the running status that infosystem embodies; Set corresponding alarm threshold according to running status, the webpage key message extracted and threshold value are compared, and then inspires sound and light alarm device alarm, remind monitor staff system cloud gray model abnormal, thus reach the very first time and pinpoint the problems, the target of process problem.
