Excavate and early warning response analysis method based on GIS electrical network disaster data messageTechnical field
The invention belongs to the data mining of electrical network disaster and early warning response technology field, relate to a kind of based on the excavation of GIS electrical network disaster data message and early warning response analysis method.
Background technology
Electric power is the national pillar energy and lifeblood, simultaneously because network system majority is directly exposed under natural conditions, is subject to environmental factor and Effect of Natural Disaster larger.The generation of all kinds of disasteies is often directly threatening the safe operation of network system, even causes serious electrical network to destroy and large area blackout, and then has influence on people's normal production, life and social stablizing.
In recent years, along with all kinds of natural disaster monitoring systems of electrical network constantly occur, having accumulated a large amount of on-the-spot historical datas, is that electric power netting safe running provides support and seems very important but how to excavate and analyze these monitor datas.
Therefore, excavate and early warning response analysis based on GIS electrical network disaster data message, can accurate and effective extract all kinds of disaster informations to electric network influencing, adopt example data digging technology to mate corresponding Disposal Measures simultaneously, for the catastrophe impact that reduces and prevent natural disaster on network system, and guarantee that its safety, stable operation have important meaning.
Summary of the invention
The object of the present invention is to provide a kind of based on the excavation of GIS electrical network disaster data message and early warning response analysis method, auxiliary people carry out monitoring, early warning, the emergency response management work of electrical network disaster, thereby reduce the loss that disaster is brought to power network line and equipment.
The problem to be solved in the present invention is achieved by the following technical solution.
Excavate and early warning response analysis method based on GIS electrical network disaster data message, the present invention includes following steps:
The first step accesses government and provides in advance contingent disaster information in generalized information system;
Second step is set up how associated compound Hazard Assessment model the disaster information in the past occurring is carried out to analysis and assessment in generalized information system, and comprehensive government's forecast information and comprehensive historical data analysis result provide possibility and the loss that electrical network disaster occurs;
The 3rd step, based on the analysis result of second step, exemplary applications data mining technology is found out the emergent successful measure of disaster was occurred in the past from case library, provides emergency response decision-making technic to the possibility and the loss that occur electrical network disaster;
The 4th step is finally carried out visual by disaster consequence and emergent decision-making on generalized information system platform on electrical network emphasis management and control circuit and facility information.
First, accept government and provide in advance the disaster informations such as contingent earthquake, flood, snow disaster, thunderbolt, strong wind, mountain fire, landslide; Adopt the methods such as step analysis, artificial neural network, logistic recurrence, statistic to set up how associated compound Hazard Assessment model to historical data analysis; Comprehensive above analysis result provides possibility and the loss that certain disaster occurs.
On this basis, application data digging technology is found out the successful measure of calamity emergency was occurred in the past from case library, provides emergency response decision-making technic to the possibility and the loss that occur all kinds of disasters, is convenient to carry out fast emergency repair work.
Finally, by the organic GIS of the being dissolved into platform of relevant art submodule for supporting all kinds of disasteies of excavation, and show that disaster may cover electrical network key line and equipment, and be convenient to departments at different levels and carry out fast emergency, reduce the loss that disaster is brought to electrical network.
The invention has the beneficial effects as follows, provide in advance contingent all kinds of disaster information by accepting government; Adopt how associated compound Hazard Assessment model to historical data analysis, comprehensive government's forecast information and comprehensive historical data analysis result provide possibility and the loss that certain disaster occurs; From case library, find out the successful measure of calamity emergency occurred in the past, on generalized information system platform, show that disaster may cover electrical network key line and equipment, be convenient to carry out fast emergency repair work.

Embodiment
Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
Excavate and early warning response analysis method based on GIS electrical network disaster data message, the present invention includes following steps:
The first step accesses government and provides in advance contingent disaster information in generalized information system;
Second step is set up how associated compound Hazard Assessment model the disaster information in the past occurring is carried out to analysis and assessment in generalized information system, and comprehensive government's forecast information and comprehensive historical data analysis result provide possibility and the loss that electrical network disaster occurs;
The 3rd step, based on the analysis result of second step, exemplary applications data mining technology is found out the emergent successful measure of disaster was occurred in the past from case library, provides emergency response decision-making technic to the possibility and the loss that occur electrical network disaster;
The 4th step is finally carried out visual by disaster consequence and emergent decision-making on generalized information system platform on electrical network emphasis management and control circuit and facility information.
As shown in Figure 1, provided by the invention based on the excavation of GIS electrical network disaster data message and prewarning analysis system, (1) access government provides contingent earthquake in advance, flood, snow disaster, thunderbolt, strong wind, mountain fire, the disaster informations such as landslide, (2) adopt step analysis, artificial neural network, logistic returns, the methods such as statistic are set up how associated compound Hazard Assessment model historical Various types of data are analyzed, (3) comprehensive government's forecast information and comprehensive historical data analysis result provide possibility and the loss that certain disaster occurs, from case library, find out the successful measure of calamity emergency occurred in the past, (4) on generalized information system platform, show that disaster may cover electrical network key line and equipment, be convenient to carry out fast emergency repair work.
As shown in Figure 2, example data digging technology flow process, in the time running into a new problem, first association processed the experience of Similar Problems in the past, in case library, find out immediate old example with it, again according to corresponding the adjusting of the difference of new situation, thus the way of the new problem that is resolved form new example.Wherein: retrieval: according to problem to be solved for information about, find immediate example collection with it from case library; Reuse: from the one group of example retrieving, obtain method for solving, if completely eligible, directly application, otherwise re-use after revising; Revise: from similar example, revise and solve scheme to be applicable to new problem; Preserve: new example and explanation are deposited in case library according to certain principle.
