Step S3, load step, the monitoring station information of the required monitoring of loading on described GIS geographic information map;
Step S4, query steps, inquiry transient event information, the transient event information of promptly inquiring about the monitoring station;
Step S5 has judged whether the untreated new events of fixed time scope, i.e. whether the time of electric energy quality monitoring system every interval appointment, checking has new untreated transient event to take place,
If have, then enter step S6;
If do not have, then directly enter step S7;
Step S6 reloads step, for the untreated transient event that is checked through in the fixed time scope among the step S5, reloads the corresponding monitoring station information on the GIS geographic information map, and points out by sound;
Step S7, the time-delay step was returned step S4 after promptly delaying time n minute, and wherein n is a positive number.
The above-mentioned transient event alarming method that is used for electric energy quality monitoring system, wherein, described GIS geographic information map layering shows to possess some layerings, comprises administrative division, road traffic, electric system figure, monitoring station or monitoring point distribution plan.
The above-mentioned transient event alarming method that is used for electric energy quality monitoring system, wherein, the icon sizes of monitoring station on the GIS geographic information map during described GIS geographic information map layering shows just determined by its electric pressure, a monitoring station is installed a plurality of monitoring terminals down, when mouse moves on this monitoring station icon, with the mode of tabulation show all monitoring terminal representative icon that this website installs, monitoring terminal title with and event quantity.
The above-mentioned transient event alarming method that is used for electric energy quality monitoring system, wherein, the layering of described GIS geographic information map can be hidden as required.
The above-mentioned transient event alarming method that is used for electric energy quality monitoring system wherein, among the step S6, for untreated transient event, when reloading the corresponding monitoring station information on the GIS geographic information map, is divided into two kinds with the icon of this monitoring station:
A kind of is green, represents all monitoring terminals in this station non-transient incident in the time range of inquiry;
A kind of redness for flashing represents that the interior monitoring terminal of this website monitors the quality of power supply incident more than 1 at least.
The invention has the beneficial effects as follows: the present invention reminds staff and user based on the multiple type of alarm of GIS (Geographic Information System) geographic information map, thereby solve the quasi real time property and the initiative of transient event alarming, a situation arises for transient event directly perceived, vivid, that punctual demonstration electric energy quality monitoring system monitors.
Description of drawings
Fig. 1 is the process flow diagram that is used for the transient event alarming method of electric energy quality monitoring system of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of transient event alarming method that is used for electric energy quality monitoring system of the present invention, comprise the electric energy quality monitoring system (not shown), this electric energy quality monitoring system carries out transient event alarming by a GIS geographic information map (not shown), and it may further comprise the steps:
Step S1, the beginning step;
Step S2, initialization step, initialization GIS geographic information map;
Step S3, load step, the monitoring station information of the required monitoring of loading on the GIS geographic information map;
Step S4, query steps, inquiry transient event information, the transient event information of promptly inquiring about the monitoring station;
