Description
Technical field
The present invention relates to fire monitoring early warning technology field, and in particular to it is a kind of based on temperature data in grid operation
Fire monitoring method for early warning.
Background technique
It is existing to be based on to the continuous improvement that accurate data analysis requires with the application that deepens continuously of power grid meteorological data
The dotted data format of weather monitoring station has been unable to meet increasing service application demand, and the power supply area of electric system increases
Greatly, influence of the meteorologic factor to electric system is not reflected on a little not instead of on the whole, in general, predicts the geography in area
Range is all bigger, and all subregion influences the temperature of the principal element such as various regions of grid equipment operation, rainfall feelings in estimation range
Condition etc. makes a big difference.
Working method of the grid service as a kind of innovation, according to the theory of mesh-managing, by grid equipment data network
It formats and carries out pool integration with meteorological data gridding and power network GIS platform, while using electronic map and present information skill
Art, within a certain area scientific grid division.The accuracy that meteorological data is improved using grid service, is reasonably accurate estimated
All kinds of meteorology real time data variation tendencies, it is significant for basic weather forecast and grid equipment data real-time monitoring.
Surface-based observing station data confidence level with higher, but for regional, website is observed in spatial distribution
State is dredged in the presence of Dong Mixi discontinuously, is significantly presented, has larger impact to the Grid data quality based on ground observation.
And in the prior art, when according to that whether fire can occur in temperature prediction region, carried out generally according to Current Temperatures
Differentiate, or make the difference being determined with Current Temperatures according to the temperature data that meteorological satellite is sent, and such methods are not examined
Consider the temperature fluctuation in one day, the data of judgement are inaccurate；Simultaneously in data transmission procedure, based on existing framework without
Decree data forwarding is mutually separated with control, to cause system update slow when system is upgraded or adds new application；
The size for reflecting fire possibility occurrence is also failed to, whether event is urgent.
The present invention is intended to seek a kind of new approaches in gridded data service, according to grid equipment and meteorological prediction data pair
Electrical network facilities region carries out gridding, and establishing meteorological data influences the accuracy of prediction on gridding grid equipment.
Summary of the invention
The purpose of the present invention is what is be achieved through the following technical solutions.
To solve the above-mentioned problems, the present invention provides a kind of monitorings based on gridding meteorological data in grid operation
Method for early warning, which comprises
Step 1): according to the province GIS map, forming vector quantization grid, the grid be using n*n as unit region,
An interchanger is set in each practical corresponding region of vector quantization grid institute, n is greater than 1 natural number.
Further, include electrical network facilities basic data in the province GIS map, specifically include: title, GIS are three-dimensional
Map reference, height above sea level, affiliated compass of competency, on-stream time, time of completion, establishment type, all types of facility three-dimensional space datas,
Personnel's type, personnel amount, the preset threshold of each weather category.
Step 2): the province, each electrical network facilities temperature sensor temperature data D collected obtained in real time are directed to
[d1,d2,…dn2], and by D [d1,d2,…dn2] be associated with into the vector quantization grid；
Further: the temperature data D [d that will be acquired in real time1,d2,…dn2], to correspond to the side of each vector quantization grid
Formula is shown at the display device of exchange.
Step 3): by temperature data collected in each vector quantization grid respectively through the interchanger of corresponding region
It is transmitted to total data analysis module, the total data analysis module is adopted each sensor of each electrical network facilities obtained in real time
Temperature data D [the d of collection1,d2,…dn2] stored；
Further, the monitoring and pre-alarming method, further includes: the historical temperature data duration of storage is 1.5 hours,
And the historical temperature data of the storage is then automatically deleted after 1.5 hours.
Step 4): the scoring of fire hazard possibility is carried out to region corresponding to each grid；In conjunction with history fire hazard
Possibility scoring is determined a need for carrying out data inspection to each sensor of each electrical network facilities and be adjusted, if so, executing step
It is rapid 5), if it is not, thening follow the steps 6)；
Further, each vector quantization grid practical corresponding region the scoring of history fire hazard possibility it is equal
It is stored in the scoring memory module in total data analysis module, is not deleted.
Further, when carrying out the scoring of fire hazard possibility to region corresponding to each grid, following step is executed
It is rapid:
A) it is corresponding to obtain actual area corresponding to all vector quantization grids that meteorological satellite is sent for total data analysis module
The same day temperature data, and calculate two the same day temperature on averageAnd T2=A+B/2, wherein A
For same day maximum temperature, B is same day minimum temperature, and fire hazard possibility scoring factor C is arranged.
B) if any point-in-time of the current time between 0:00-10:00 or 16:00-24:00, calculates fire hazard
