Embodiment
Below be described in detail at the have a power failure embodiment of method and system of monitoring of the present invention.
At first the embodiment of the method for monitoring at having a power failure is described.
As shown in Figure 1, be the have a power failure schematic flow sheet of method embodiment of monitoring of the present invention.Comprise step:
Step S101: the coordinate of each equipment of the power-off event influence that reception distribution Geographic Information System sends;
Step S102: according to coordinate, the topological connection relation of each equipment in the distribution Geographic Information System of each equipment, determine the highlighted track of each equipment;
Wherein, obtain the initial power failure equipments of power-off event correspondence by the distribution Geographic Information System, to the power failure equipments surface analysis that has a power failure, determine the coordinate of each equipment of power-off event influence.
Each power-off event is to there being one or more initial power failure equipments.If causing polylith zone to have a power failure, a plurality of equipment failures are defined as same having a power failure on a large scale during event, can attach when transmitting this power-off event and transmit a plurality of initial power failure equipments, distribution GIS(Geographic Information System, Geographic Information System) analyzes the power failure marketing scope of a plurality of equipment.
By the surface analysis that has a power failure of the corresponding initial power failure equipments of the power-off event of distribution GIS, drawing the coordinate of the equipment of the influence that has a power failure.As shown in Figure 2, determine the schematic flow sheet of coordinate of each equipment of power-off event influence for the present invention, its concrete steps comprise:
Step S201: all devices of analyzing the power-off event influence:
As starting point, utilize the topological analysis function of distribution GIS that power failure equipments is carried out downstream analysis with initial power failure equipments.Downstream analysis namely utilizes topological analysis to calculate the power-supply device of power failure equipments, filters out power-supply device to the armamentarium between the power failure equipments, and remaining is that upstream device is gathered.Analyze the armamentarium object (comprising mesolow) of power failure equipments load direction.
Step S202: filter redundant equipment:
In the cluster tool that analysis obtains, the equipment in the room, point device outside the room and the face equipment outside the room are filtered out, only keep the line equipment outside the room.Certainly, retaining device is set as required, and this programme has only kept the line equipment outside the room in order to improve the speed of subsequent load.
Step S203: the coordinate of determining each equipment:
Travel through the line equipment outside each room, be saved in the database by the sequence of whole end points of the figure of line equipment, form the coordinate of each equipment of power-off event influence.
The coordinate of each equipment of the power-off event influence that reception distribution Geographic Information System sends according to coordinate, the topological connection relation of each equipment in the distribution Geographic Information System of each equipment, is determined the highlighted track of each equipment.Can adopt the SVG principle to determine the highlighted track of each equipment, wherein, have equipment component after the power failure and recover again, namely we often are called telegram in reply, also show for this equipment component, and therefore highlighted track is the highlighted track that stops the equipment of sending a telegram in reply.Its concrete steps comprise:
1) draw the circuit track that stops sending a telegram in reply:
The power failure Analysis Service that provides by generalized information system analyzes the power failure coverage, gathers the relevant device coordinate information, is pre-stored in the database.According to the power failure scope device coordinate information of having analyzed, topological relation and the topological level of the equipment of deferring in generalized information system drawn out at map and stopped to send a telegram in reply the circuit track accordingly;
2) calculate the event round dot coordinate that stops sending a telegram in reply:
Point according to numerous equipment distributions at random, and according to (x1+x2....xn)/n, (y1+y2....yn)/n obtain at last a middle point coordinate (x, y), with this mid point be middle point location drawn stop the event round dot of sending a telegram in reply, namely as the power failure point of power-off event.When checking whole map, can not show each equipment of each power-off event influence, and each power-off event only shows a point, namely has a power failure a little, can reduce the loading quantity of whole map like this, improves display speed;
Guarantee when 3) power-off event is located that track all shows:
Obtain the resolution of computer screen and make out long (l) and high (h), the ultimate range coordinate points that draws according to the distance between all points at random and the true origin and the coordinate points (being maximum horizontal ordinate point and minimum horizontal ordinate point) of bee-line, thereby calculate track shared maximum area in screen, the scaling of the resolution of combining screen and map guarantees that its track shows fully again;
4) remove the outer point of screen during amplifieroperation:
In order to reduce the svg data volume that system's page loads, need the extraneous svg data point of screen to remove, namely the point coordinate of the coordinate of shielding device outside preset range reached the purpose of accelerating display speed.Preset range can for:
Certainly, preset range can be set as required, and present embodiment is only lifted wherein a kind of optimal way, can make it reach better display effect.Other modes do not repeat them here.
5) the power failure track is showed:
Utilize the technology of svg figure, flicker stops the track of telegram in reply event correspondence, plays up different default colors according to the power failure of event with the telegram in reply sign, has a power failure green sign telegram in reply such as the redness sign.
6) drag or zoom operations and the svg figure coordinate that causes when changing in execution, the screen coordinate transfer function that utilizes the GIS platform to carry, screen coordinate to current svg figure calculates, again play up new svg figure then, to reach under different map displaying ratios, stop the track of sending a telegram in reply, fully according to the convergent-divergent of equipment and synchronously the purpose of convergent-divergent.
Present embodiment is in conjunction with the power failure scope of geographical Background location power-off event, and the particular location of real-time exhibition power-off event intuitively reflects the coverage of power-off event.Line chart in conjunction with circuit in the distribution Geographic Information System represents simultaneously, and the line looped network situation of assistant analysis power supply interrupted district improves the formulation power failure and deals with scheme efficient.
This programme can also obtain each transformer of power-off event influence, determines the customer interrupted tabulation that described power-off event is corresponding according to default transformer with each transformer of customer relationship, power-off event influence; Wherein, each transformer of described power-off event influence calls described distribution Geographic Information System power failure surface analysis service by the distribution production system and determines.
In a specific embodiment, also can directly obtain and show the customer interrupted tabulation.Wherein, call distribution Geographic Information System power failure surface analysis service by the distribution production system, obtain each transformer of power-off event influence; Determine customer interrupted tabulation that power-off event corresponding according to default transformer with each transformer of customer relationship, power-off event influence by the distribution production system.
Further, in a specific embodiment, can also obtain the type of power-off event, according to the customer interrupted quantity that dissimilar power-off event correspondences is determined in type and the customer interrupted tabulation of power-off event, the power-off event type can be pre-class, failure classes, the class etc. of avoiding the peak hour of arranging;
