As in figure 2 it is shown, the interconnected method of a kind of integration SCADA and GIS, comprise the following steps:
1) generalized information system collection geography distribution pattern information be changed to the image information of generalized information system at GIS data transit server, geographical distribution figure information includes the coordinate position of graphic element, classification, mark, attribute and device parameter, and the image line of the image information of generalized information system is with plant stand, valve, pressure tap and branch point segmentation；
2) between generalized information system and SCADA system, set up data link by GIS/OLE interface, specifically include following steps:
21) DAIS client provides to DAIS server and subscribes to data；
22) SCADA data server carries out inquiring about and obtaining feedback information to DAIS server；
3) adopting the mode that ole object embeds to import in SCADA data server by the image information of generalized information system, the image information data exchange of SCADA system and GIS object adopts the mode of ASCII character exchange files；
4) image information of the generalized information system of importing is carried out converting system diagram information to by SCADA data server, and shows on a client.
The SCADA system of actual motion and generalized information system, according to pertinent regulations, belong to the network of different level of security, it is physically-isolated for being typically on network, in this case, general most employing swap file technology, adopt in this way, existing network can be carried out special safe handling, under normal circumstances, when adopting swap file technology, network structure is generally adopted bridge machine, bridge machine is installed two pieces of network interface cards, one piece is connected with SCADA Real-time Network, one piece is connected with GIS net, Real-time Network net send in real time and historical data to GIS net by certain stipulations, netted by GIS and oneself process.In above-mentioned network structure mode, need mounting interface retransmission process on gateway machine, carry out processing according to the format protocol of agreement by the real time data of the Real-time Network received by first piece of network interface card and generate swap file, send data file again through second piece of network interface card to the GIS server netted, or directly on bridge machine, generate relevant data file.As GIS net work station wants to check that telemechanical is in real time or historical data, also to install and to run the picture program of display real time data on a workstation, data file is resolved, and show on GIS figure.
The Dynamic cata exchange of SCADA system and GIS object adopts ASCII character exchange files mode.In systems the swap file of self-defined ASCII character form is generally used for the mutual of real time data and Unit account of plant data.Generalized information system file name according to a preconcerted arrangement, file is read to corresponding storage positions of files, resolution file content, and the measuring point by setting in generalized information system in advance, find relevant position, video data, when account data are transformed into SCADA system by GIS, the similar above method of file format of employing.
Interface mode refers to that SCADA system realizes the Dynamic cata exchange of GISSCADA by computer network at application layer.GIS and SCADA system remain two relatively independent systems, respective independent maintenance data, graphing, and simply by the access of some data, technology of sharing, allowing can have the mutual of data between system.Owing to SADA and GIS is the relatively independent systems of two sets, adopts each independent data form, so also must there be respective topological analysis software, so cause most of network topology of SCADA graphics system and the network topology of generalized information system to describe inconsistent.Owing to topological analysis and real time data are the bases of advanced applied software, on GIS figure, being difficulty with senior application in this way so adopting, typically just accomplishing the display about real time data, advanced analysis result of calculation.In order to solve the reunification of network topology and figure, it is necessary to the geographical wiring diagram stored by GIS topology mode to be converted into the orthogonal graph stored by application system topology mode.In order to ensure that favourable conversions GIS provider and SCADA provider have needed following work:
Geographical distribution figure is changed by generalized information system to orthogonal system figure.Convert coordinate position, element class, element identifier, element connection relation, display properties and device parameter that the orthogonal system figure information content obtained comprises graphic elements.SCADA provider is translated the orthogonal graph generating scheduling energy display device parameter, and for data base administration, attendant generates data base.
In the orthogonal system figure information that generalized information system is submitted to, circuit is carried out reduction with conductor impedance information in plant stand, equipment, test point orthogonal system figure by generalized information system.
SCADA system utilizes the work information detected to carry out running calculating, and generalized information system completes the topological relation housekeeping of equipment.In topological relation, adjustment valve, cut-out, pipeline represent by two end element, and pump, filling point, power supply point etc. represent with single-ended element, and identify the connecting element such as backbone, tie.The element physical parametric data of analysis of network submits to SCADA system together after correct merger.
