The method comprises the following steps of importing an electronic map which corresponds to an area where a gas delivery pipeline is arranged; constructing a two-dimensional layout map of the gas delivery pipeline on the electronic map; acquiring cross-section data of the gas delivery pipeline; constructing a three-dimensional map of the gas delivery pipeline on the electronic map according to the two-dimensional layout map and the cross-section data; importing monitoring data; and combining the monitoring data to the three-dimensional map. By the method for establishing the pipeline geographic information system, a geographic information system of the gas delivery pipeline, which contains rich monitoring data, can be established, various parameters of the gas delivery pipeline can be checked at any time, data exception is timely processed and potential safety hazards are avoided.
Description
Technical field
The present invention relates to the monitoring technique of gas transmission pipeline, relate in particular to a kind of method of setting up the Geographic Information System (GIS) of gas transmission pipeline.
Background technology
In the industries such as oil, chemical industry, coal, electric power, metallurgy, coking, need to use a large amount of reacting gas, be all much inflammable and explosive or toxic and harmful in these gases.Due in above-mentioned industry to being in great demand of gas, therefore typically using gas transmission pipeline carries these gas.Gas transmission pipeline can be laid with the gas of realizing long distance and carry in vast scope, pipeline is made by metal or corrosion resistant nonmetallic materials usually,, although pipeline is firmly, for a long time, is in use procedure, also there will be unavoidably some faults., because mostly these gases are inflammable and explosive or poisonous and hazardous gas, can have a strong impact on surrounding environment after occurring leaking, and bring potential safety hazard.
If pipeline breaks down, so usually can cause correlation parameter,, such as marked change appears in temperature, humidity, gas concentration, intraductal atmospheric pressure etc., therefore, the correlation parameter of gas transmission pipeline is monitored, can in time find pipeline fault.
For the monitoring of gas transmission pipeline, because area is larger, parameter is a lot, how to realize that effective Real Time Monitoring is a difficult problem.Geographic Information System (Geographic Information System, GIS) is an effective means that solves a monitoring difficult problem.Geographic Information System is take geospatial database as basis, under the support of computer software and hardware, use the theory of systems engineering and information science, scientific management and analysis-by-synthesis have the geodata of space intension, so that the technological system of the information needed such as management, decision-making to be provided.Briefly, GIS is overall treatment and a kind of technological system of analyzing geographical spatial data, is to survey and draw to be measured as basis, uses database as the data source of data storing and use, the instant technology of global space analysis take computer programming as platform.
Summary of the invention
The present invention is intended to propose the method for a kind of foundation for the GIS of gas transmission pipeline.
According to one embodiment of the invention, a kind of method of setting up the pipeline Geographic Information System is proposed, comprise following step:
Import electronic chart, electronic chart is corresponding to the zone of arranging gas transmission pipeline;
Build the two-dimentional Butut of gas transmission pipeline on electronic chart;
Obtain the cross-section data of gas transmission pipeline;
Build the three-dimensional plot of gas transmission pipeline according to two-dimentional Butut and cross-section data on electronic chart;
Import monitor data;
Monitor data is merged in described three-dimensional plot.
In one embodiment, the cross-section data that obtains gas transmission pipeline comprises the spacing distance between gaseous species, pipe thickness and the pipeline of diameter, conveying of each pipeline on a cross section that obtains gas transmission pipeline.The cross-section data that obtains gas transmission pipeline comprises and obtains successively the cross-section data in each cross section of gas transmission pipeline take 0.5m as interval.
In one embodiment, the three-dimensional plot that builds gas transmission pipeline according to two-dimentional Butut and cross-section data on electronic chart is included in mark control point in three-dimensional plot.Control point monitoring temperature, humidity, index gas concentration, pipeline internal gas pressure, gas in pipelines flow velocity.Accordingly, monitor data comprises temperature data, humidity data, index gas concentration data, pipeline internal gas pressure data, gas in pipelines flow speed data.
In one embodiment, monitor data floating demonstration in three-dimensional plot.
The method of setting up the pipeline Geographic Information System of the present invention can be set up a kind of Geographic Information System that comprises the gas transmission pipeline that enriches monitor data, can check the various parameters of gas transmission pipeline at any time, in time process when finding data exception, avoid occurring potential safety hazard.
Description of drawings
Fig. 1 has disclosed the process flow diagram according to the method for setting up the pipeline Geographic Information System of one embodiment of the invention.
Embodiment
With reference to shown in Figure 1, the present invention has disclosed a kind of method of setting up pipeline Geographic Information System (GIS), and the method 100 comprises following step:
101, import electronic chart, electronic chart is corresponding to the zone of arranging gas transmission pipeline., because gas transmission pipeline is to be arranged in a larger zone, at first need to import this regional electronic chart as the basis of setting up GIS.
102, build the two-dimentional Butut of gas transmission pipeline on electronic chart.In step 102, on the basis of the electronic chart that imports, build the trend of gas transmission pipeline in previous step 101, formed the electronic chart that comprises the gas transmission pipeline trend.
103, obtain the cross-section data of gas transmission pipeline.In step 103, the cross-section data that obtains gas transmission pipeline comprises the spacing distance between gaseous species, pipe thickness and the pipeline of diameter, conveying of each pipeline on a cross section that obtains gas transmission pipeline.In one embodiment, accurate as far as possible for the data that make GIS, obtain successively the cross-section data in each cross section of described gas transmission pipeline take 0.5m as interval.The value at interval depends on the requirement of data precision fully,, if wish that data are more accurate, can dwindle interval so, if less demanding to the data precision can increase interval so.
104, build the three-dimensional plot of gas transmission pipeline according to two-dimentional Butut and cross-section data on electronic chart.Step 104 can realize by existing any dimensional Modeling Technology.In one embodiment, also be included in mark control point in three-dimensional plot in this step 104.The effect of control point is monitoring temperature, humidity, index gas concentration, pipeline internal gas pressure, gas in pipelines flow velocity.
105, import monitor data.In one embodiment, monitor data comprises temperature data, humidity data, index gas concentration data, pipeline internal gas pressure data, gas in pipelines flow speed data.
106, monitor data is merged in three-dimensional plot.In one embodiment, monitor data is floating demonstration in three-dimensional plot, usually monitor data can be presented at corresponding control point near.
The method of setting up the pipeline Geographic Information System of the present invention can be set up a kind of Geographic Information System that comprises the gas transmission pipeline that enriches monitor data, can check the various parameters of gas transmission pipeline at any time, in time process when finding data exception, avoid occurring potential safety hazard.
