(2) fan monitoring is visual

Controlled wind machine equipment is installed in Switching Station, and the to the effect that fan operation state of fan monitoring, in the time of but cannot opening operation, reports to the police when blower fan works automatically, and automatically locates blower fan position in GIS figure.In GIS figure, can identify fan operation state by additional character and show intuitively.Meanwhile, in GIS figure, can to blower fan, carry out remote opening or shutoff operation easily.

(3) video monitoring is visual

Video monitoring equipment is installed in Switching Station, for supporting watch-dog operation that solar power supply unit is installed.

Video monitoring obtains the inner field data of Switching Station by the mode of video, can observe from all angles the reading of situation, on off state and table in Switching Station, realizes the real time monitoring to Switching Station inner case and machine operation.Support split screen to show video information, can or monitor many Switching Stations a plurality of positions of same Switching Station simultaneously.

(4) light monitoring is visual

Controlled electric light is installed in Switching Station, on GIS figure, is shown the state of light in Switching Station, can to light, carry out remote opening or shutoff operation easily.

(5) cable system thematic map

System is painted with the GIS thematic maps such as thermometric distribution thematic map, fan monitoring thematic map, distribution line distribution thematic map and distribution facility distribution thematic map.Cable sectional drawing comprises two kinds, cross-sectional view and skiagraph.Cross-sectional view is for showing intuitively the situation that takies of cable aperture, and skiagraph is for showing the gradient that cable is along the line; Thermometric distribution thematic map is optical fiber temperature-measurement equipment coverage area diagram; Fan monitoring distribution thematic map refers to the coverage area diagram of Switching Station watch-dog.

(6) dangerous point is visual

In three-dimensional scenic, provide the drafting function to various dangerous points and construction site.During drafting, user only need select on earth's surface the current dangerous point region that needs drafting, automatically according to dangerous point type, generates corresponding three-dimensional model.

4, interactive inquiry

System should provide powerful, flexible, various query function, can support the multiple inquiry modes such as accurate inquiry, fuzzy query, query composition, in database, arbitrary fields can be as querying condition, and can realize the interactive inquiry of isomeric data in disparate databases.

5, report form statistics analysis

Based on too development Reports module, form need be supported to extract and to represent required data from main flow oracle database.

Form need support the pictorial statement such as broken line graph, histogram, pie chart to show, the various figures that represent can switch in real time and represent, and can support that printing, Print Preview, EXCEL derive, CELL derives.

6, equipment comment

This function is the relevant regulations according to State Grid Corporation of China, every half a year, degree must be graded to distribution cable related facility, system also generates the grading form of corresponding establishment rapidly according to the data analysis of storing in database, simultaneously, can be by result with Word, the common office document form such as Excel is derived, and replaces artificial grading in the past, has significantly improved electric power personnel's work efficiency.

7, prediction early warning

Set up early warning and the alarm database of each monitoring parameter, and automatically to collecting parameter, judge, for qualified parameter, according to the rule that system is predetermined, carry out in every way early warning and warning, as push away screen, acousto-optic, note etc., utilize the various ways such as three-dimension GIS, chart, curve, virtual instrument, animation, the multidimensional that realizes early warning and warning is visual simultaneously.

In conjunction with online monitoring information, Monitoring Data is carried out to grade, qualitative classification, and by integrating various information and on-site supervision information acquisition, respectively for accident of different nature, obtain prediction early warning information, and carry out Macro or mass analysis; On the basis that information is analyzed, call relevant model, carry out simulation and forecast and comprehensive analysis, by result carry out two, three-dimensional visualization.
