Fig. 1 is that log analysis methodology of the present invention is always schemed;
Fig. 2 is an on-line analysis method flow diagram of the present invention;
Below in conjunction with accompanying drawing content of the present invention is described in further detail.
Embodiment
As shown in Figure 1 and Figure 2, the basic description:
The automated information recording method is to be based upon in the flow process of sequential logic, at first carries out the configuration of automated information object, and different automated information objects mainly is that the information format with different communication protocols is reflected, as IEC-870-5-103; IEC870-5-101; IEC61850 etc., the different information communication form that the various types of communication stipulations are expressed, for these communication formats be again with different communication modes transmit, mutual, as Ethernet, all kinds of fieldbus, conventional serial communication etc.Need be configured description to these contents, set up the configuration file of describing, realize the specific aim collocation method of the record automated information of intercepting.Secondly, carry out the self diagnosis inspection of automated information record, mainly communicate technology evaluation inspections such as mode, storage medium, record environment, capacity, time synchronized, can carry out next step after inspection is correct.The 3rd, carry out the setting of display mode, be primarily aimed at a high speed, the adjusting of methods such as big capacity information shows deletes, important mark, information extraction and shielding.Carry out the important recording processing step and the method for automated information subsequently;
(1) intercepting of information according to the communication mode that is provided with, takes corresponding communication to intercept mode, and information and the information format that listens to is left intact, do not load any supplementary, keeps the original appearance of infomational message.
(2) record of infomational message is given to load split-second precision information in the interception information, and temporal information may be interrupted the complete message of a frame, is index with the temporal information, and the information normalization with listening to is temporarily stored in the buffer area.
(3) working area information reaches when overflowing restriction, carries out data storage processing, at first calculates the relation in memory space and space, working area, when space, working area during,, be to circulate to cover storage according to the storage policy of setting greater than memory space, still storage stops, and prompting.
(4) according to function selecting, be to proceed limit storage, limit on-line analysis, still only store later off-line analysis.
(5), implement in case of necessity to report to the police and the mark of important information according to the result of on-line analysis.
(6) according to function selecting, the canned data content is carried out filtering screening and location, the information segment of needs is extracted, and temporary.Remove additional temporal information, recover original communication protocol form.
(7) communication mode of information by setting after the screening as required externally sends the automated information source that simulation is relevant.
The description of on-line analysis part:
Followingly begin according to logic flow:
There are data the data field of storage, then carries out the message structure analysis; Otherwise communications reception is made mistakes, and reconfigures messaging parameter.
The infomational message structure meets message structure, then carries out message checking, otherwise the structure mistake.
The inspection message message checking, verification is correct, and then carry out stipulations and explain, otherwise the verification mistake.
Stipulations explain that the dissimilar stipulations according to being provided with make an explanation targetedly, check that message is complete, completely then carry out Time-Series analysis, file otherwise write down incomplete message.
Check the message sequential, satisfy the sequential requirement, then carry out the inspection of message content logical type, otherwise the sequential mistake.
Check the message information content, content meets the agreement of stipulations, then searches for the matching content of setting, otherwise interior fault-tolerant.
Search matching content continuously,, find, then carry out content analysis until having looked for, otherwise, return.
The content that finds is a control command, be, then control command demonstration and record storage, control procedure is returned, and checks then whether control is successful, success, then this content of displayed record and storage are submitted to and are returned.Otherwise, check whether control command is sent, send record and show the execution dot information, otherwise control command is not sent.
Whether be not control command, then check to be telemetry intelligence (TELINT), then write down and store this telemetry intelligence (TELINT), the whether transition of continuous review telemetry intelligence (TELINT) is until having looked into.As remote measurement transition, demonstration and storage are submitted to and are returned.
Not telemetry intelligence (TELINT), check to be whether remote signalling information, then record and this remote signalling information of the West Lake, village, whether displacement of continuous review remote signalling until checking out, as displacement, then shows and store submission and return.
This recording method can realize to IEC870-5-101 102 103 104, application layer such as IEC61850-9-2, MMS, GOOSE, IEEE1588, SNTP, GMRP, DNP, CDT agreement and TCP/IP and transport layer protocol record and analytic function.
