A kind of three-dimensional position modeling method of low-voltage intelligent ammeterTechnical field
The present invention is to be related to the integrated standardization management domain of intelligent electric meter positional information under low pressure, more particularly, toA kind of three-dimensional position modeling method of low-voltage intelligent ammeter.
Background technology
In recent years, power market reform, energy policy adjustment and the development of distributed energy technology, between power network and userContact become more close, Demand Side Response ability improve constantly.But traditional motor meter offer function is limited, precisionIt can not meet the requirement to user data collection under the new situation with quantification stability.Therefore, using intelligent electric meter as number in power distribution networkAccording to collection basic equipment, detailed electricity consumption data was both provided the user with, it is managed oneself electricity consumption behavior, and carried for power supply enterpriseFor user power utilization demand foundation, while also allow for detecting failure and administration of power networks control.
With " Every household has an ammeter, pipe electricity to family " carrying out in an all-round way for policy and being widely popularized for intelligent electric meter, resident and enterpriseIntelligent electric meter quantity drastically increase, distribution situation scale is big and complicated, considerably increases power network operation maintenance personnel field reviewWorkload, so that handling failure efficiency is low, aggravate power supply enterprise and the tight relationship of user.
Found through the literature search to prior art, the PDA collection O＆M information management systems based on GPS positioning technologyDesign (design [J] the Silicon Valleys of PDA collection O＆M information management systems of the Chen Fengrui based on GPS positioning technology, 2013:17-18) numbering and latitude and longitude information of intelligent electric meter are obtained by GPS positioning technology, so as to find the position of target ammeter；Electricity consumptionInformation gathering exception placement technology is studied（Zhao Li, He Rong, Pu Jian, fellow villagers Zhao, the collection of Zheng Yingchun power informations are differentNormal placement technology research [J] electrical technologies, 2014:54-57）By installing Mobile phone card at ammeter, cell-phone number is utilizedCode identification intelligent ammeter accurate location.Document above carries out intelligent electric meter positioning using the methods of mobile terminal, GPS location, butIt is that have ignored existing mount message, and widely using with intelligent electric meter, different building interior structures can cause O＆MWork is more complicated, causes a large amount of wastes of grid company manpower and materials and the contradiction new with user.
The content of the invention
The present invention is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of three-dimensional of low-voltage intelligent ammeterPosition modeling method, comprehensive intelligent ammeter ID number, place floor, ownership room number, installation floor level positional information, establishes intelligenceAmmeter three-dimensional coordinate data storehouse, and combine building threedimensional model and ammeter particular location is showed with visualization technique.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of three-dimensional position of low-voltage intelligent ammeterModeling method, it is characterised in that comprise the following steps：
S1：The ID number of input building Inner intelligent electric meters；
S2：Record the affiliated floor of corresponding intelligent electric meter, affiliated Plane Location coordinate, ownership room number, installation building
The plan-position of layer；
S3：Floor Z where integrated treatment obtains ammeter, place floor level coordinate (x, y), determines that ammeter exists
Three-dimensional coordinate (x, y, z) in building；
S4：Verify and handle intelligent electric meter space coordinates；
S5：Establish intelligent electric meter three-dimensional coordinate data storehouse under secondary network；
S6：With locus of the visualization technique where intelligent electric meter is determined in building threedimensional model.
Further, in step S3, every terms of information is analyzed and processed, lower left angular vertex is built as original using design drawing top viewPoint, using origin be starting point parallel construction thing main entrance direction as x-axis, using origin as starting point design drawing front view build and groundVertical line is z-axis, and then determines y-axis, and determines coordinate (x, y, z) of the intelligent electric meter in three dimensions.
Further, in step S4, described verification content includes installing space in numbering, intelligent electric meter ID number, buildingCoordinate value, ownership room number.
Further, in step S6, described visualization technique is by using graphics software, by the floor height of some floorMarked, ammeter is marked with light tone block form, and show with numeral.
Compared with prior art, beneficial effect is：The method simple practical that the present invention is carried, makes full use of intelligent electric meter to pacifyThe existing information of dress, intelligent electric meter can be positioned to the accurate simplification of statement, and can be in three-dimensional building model directly appreciablyThe locus of intelligent electric meter is portrayed, accurate positional information is provided for field service personnel, reduces in growing intelligenceOperation maintenance personnel workload under energy ammeter background, operating efficiency and operation benefits, the section of project construction for improving centralized meter-reading systemIt is significant to learn planning etc..

Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodimentScheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawingExplanation, it is impossible to be interpreted as the limitation to this patent.
Embodiment：As shown in Figure 1,2,3, 4, a kind of three-dimensional position modeling method of low-voltage intelligent ammeter, it is specific to implementIt is as follows：
A certain intelligent electric meter is arranged at building one, and the information recorded during installation is as shown in the table：
| Intelligent electric meter ID number | |
| Belong to room number | 301 |
| Floor is installed | 3 buildings |
| Mounting plane coordinate | （8412,33451） |
The first step, collect information during currently available installation, including intelligent electric meter ID number（Identification）, installation buildingLayer, ownership room number, installation floor level coordinate value；
Second step, with design drawing top view（top）Building lower left angular vertex is origin, using origin as starting point parallel construction thingMain entrance direction is x-axis, using origin as starting point design drawing front view（front）Building and ground perpendicular are z-axis, and then determine yAxle.The information collected is analyzed and processed, determines coordinate (8412,33451,3) of the intelligent electric meter in three dimensions;
（3）Intelligent electric meter database under secondary network is established after checking treatment, content includes：Numbering（Own in same building thingIntelligent electric meter is numbered）, intelligent electric meter ID number（Identification）, installing space coordinate value, ownership unit in building（RoomNumber）；
| Numbering | Intelligent electric meter ID number | Spatial value | Belong to unit |
| … | | | |
| 32 | | （8421,33451,3） | Resident（Rooms 301） |
（4）By visualization technique, the position of intelligent electric meter is showed in three-dimensional building model.
Visualization technique is by using graphics software, the floor height of some floor is marked with numeral, by ammeter with light toneBlock form marks, and shows.Graphics software can be conventional AutoCAD or UG or proE.
