Description
Technical field
The present invention relates to a kind of power engineering Electric Power Survey method, specifically relate to a kind of power engineering field exploration method using when being convenient for carrying and being applicable to field exploration.
Background technology
The groundwork of Electric Power Survey is feasibility study, Preliminary Design Study and goes out working drawing work.Power line design department generally according to one of small scale map general design by somewhere the power circuit to another ground, principle of design be line of electric force not across residential block, can not be close to ditch, road etc. parallelly advance, as far as possible through extensive forest, the ad eundem line of electric force intersection etc. of getting along well as far as possible.But, because map scale is smaller, map is also older, thus can not correctly reflect that circuit is through regional atural object situation, so just must be to the exploration of route selection on the spot.
Traditional mode, for to carry out primary design by small scale, then by probe, and by investigation result digitizing, is inputted computer system.This mode is more original, and the data precision of investigation is very low, and investigation source book in the time carrying out digitizing, the duplication of labour, has wasted a large amount of man power and materials, inefficiency.
In recent years, be accompanied by the development of 3S technology, 3S is applied to Electric Power Survey and becomes main flow, this application presents direction, be desktop version GIS Electric Power Survey and mobile edition Electric Power Survey, lack between the two alternately, the function of 3S technology in Electric Power Survey field is not brought into play, restricted the lifting of Electric Power Survey level and quality.
Based on desktop version GIS Electric Power Engineering Reconnaissance method, can meet the major part work of Electric Power Engineering Reconnaissance, as the Electric Power Engineering Reconnaissance Software tool based on customized exploitations of platform such as AutoCAD, ArcGIS, hypergraphs.But desktop version GIS carries inconvenience, generally do not possess radio communication function.
Moving electric power engineering survey method, as " star of Electric Power Survey " of south mapping, collection are thought precious electric power data acquisition etc.By the handbook software on mobile terminal, realize the work such as data typing and coding, can Realizing Achievement output, the function such as distance measurements calculation.Mobile edition Electric Power Survey interface display is general, and achievement need to be changed and could be identified by desktop version power engineering design platform, and can not carry out the real-time, interactive of data.Tradition collection and the editor of field data, need to get back to the manual input of office and enter GIS database with compiling.This operating type Data Update cycle is long, and the very difficult guarantee of precision, brings great unreliability to GIS analysis and decision result.
Summary of the invention
The power engineering field exploration method based on mobile edition GIS that the object of the invention is the defect in order to overcome above-mentioned technology existence and propose, mobile GIS Electric Power Engineering Reconnaissance, utilize and there is IOS, Windows Mobile, the smart mobile phone of Android or other operating system, handheld pcs, personal digital assistant PDA or there is picture and text inputs, the mobile communication terminal of processing and Presentation Function, break through the use restriction of desktop GIS, compositive economy, the information of the aspects such as society, realize dynamically updating of information, it is based upon on embedding and wireless telecommunications basis, not only refer to the generalized information system that physical support moves, also not only referring to provide moving target information, neither conventional GIS simplify so that can realize GIS operation on small computer, it is one and uses the different constructed system of example of essence.
For achieving the above object, the present invention is by the following technical solutions:
A power engineering field exploration method based on mobile edition GIS, GP configuring S acquisition module, GIS engine modules, database management module, interface display module, communication module and mobile terminal database on the intelligent mobile terminal that possesses operating system; Described intelligent mobile terminal and the geographical data bank of data service center and power engineering database communicate, thereby realize power engineering field exploration; Its step is as follows:
Step 1, intelligent mobile terminal obtains gps data from geographical data bank, GPS acquisition module is resolved gps data, then intelligent mobile terminal calls that GIS engine modules is carried out coordinate conversion and invoking page display module shows current position location on map, thereby in the geographic position while of accurately locating power equipment, make staff investigate thoroughly the association attributes of power equipment at power engineering field condition, and at the scene by the association attributes typing intelligent mobile terminal of power equipment;
Step 2, GIS engine modules is according to the power equipment entity type of typing, and the discrete point that GPS acquisition module is gathered forms geographical entity, shows in real time geographical entity figure and the geographic position surveyed in interface display module;
Step 3, intelligent mobile terminal is updated to the geographical entity figure of collection and position thereof and attribute data in the database of mobile terminal, and this mobile terminal database is responsible for access and management by database management module.
In described step 2, GIS engine modules adopts the discrete point that following method gathers GPS acquisition module to form geographical entity: in the time gathering point-like geographical entity, first create a point-like geographical entity object, then utilize the graph data of the gps coordinate structure point object after conversion.
In described step 2, GIS engine modules adopts the discrete point that following method gathers GPS acquisition module to form geographical entity: according to an object collection, after all having gathered Deng points all on face body entity, carry out GIS operation and create a Method for Area Geographical Entities taking these some strings as graph data, and taking wherein as graph data, in the time gathering other on planar entity, Method for Area Geographical Entities is added to the point newly gathering in real time in the coordinate string of its figure coordinate and upgrades figure.
In described database management module, geographical entity figure is connected by unique ID number with attribute data.
Adopt the present invention of technique scheme, utilize intelligent mobile terminal that indoor three-dimensional platform need to have been taken to on-the-spot use according to scene, paint needs in conjunction with on-the-spot tune, can carry out at the scene typing and the simple editing of information, and can, by indoor editor's data back, carry out next step design effort.This method is simple in structure, practical, with low cost, easily realization.Because stored geographical spatial data and integrated many software function modules in mobile terminal, user can greatly reduced under the prerequisite that server is relied on, enjoy expediently local, real-time electric power field exploration information service.
