(1), based on netted pipeline section topological structure, support the rock gas networking pipeline of a lot of point, many terminals, support that the product oil existed at present injects branch line, point defeated ray mode;
(2) on the physical connection of pipeline, delivery technology, dispatching services Fig. 3 level, achieve the complete description to oil and gas pipes;
(3), static data that model object attribute kit oily pipeline is complete, also comprise the whole business diagnosis of oil and gas pipes calculate required for the on-the-spot real time data of sign conduit running state;
(4), each oil and gas pipes regulation and control business diagnosis calculate result, also as model object or model object attribute, be stored in pipeline regulation-control model;
(5), pipeline regulation-control model hierarchical structure, the efficiency that the digitizing input of arbitrary network pipeline and storages, access, inquiry etc. operate can be ensured;
On the basis of pipe network hierarchical link model, be model element and attribute thereof by the data abstraction involved by pipe network delivery technology, regulation and control business further, form unified oil and gas pipes regulation and control characterization model; Pipeline regulation-control model achieves the Unified Characterization of regulation and control full-service related data, becomes the data basis of each analytical calculation that is mutually related of regulation and control back-up system; It is as follows that pipeline regulation-control model comprises model element: model imported and exported by pipe net leakage rate, pipeline section model, import and export model, topological point model, user model, tank field model, tank model, gasifier model, tank;
Definition and configuring pipes example as required in software application process, and each equipment, sensor and technological process value under model can be traveled through fast by the instance handle of specific tube segment model, fast return result of calculation, completes data display;
Comprise the steps: in step 5)
Be model service configuration regulation-control model and instantiation model object at the Interface Development environment of SCADA system, regulation and control operational support system carries out by SCADA system model service the data interaction regulating and controlling business diagnosis process;
Pipeline regulation-control model achieves regulation and control operational support system and the Unified Expression of SCADA system between the two on data content and understanding, and to be two systems store in data configuration, data, the data basis of collaborative work between data access and data man-machine interaction;
Comprise the steps: in step 6)
By analyzing the man-machine interaction mode of regulation and control business diagnosis result of calculation, determining and adopting two-dimensional curve, histogram, data logger Fig. 3 to plant data display form; Based on the Plugin Mechanism of SCADA system HMI environment, design two-dimensional curve, histogram, data logger Fig. 3 plant plug-in unit pixel and according to concrete engineering requirement instantiation pixel in HMI, and bind the model object of corresponding engineering, realize the man-machine interaction of regulation and control operational support system result of calculation in SCADA system.
