Gas pipe network GIS application system and file management system solution
For a long time, the traditional way to manage gas pipe network. The file data has not been strong: the data is incomplete, the gas transfer is lacking, and the emergency is unable to learn and immediately take effective measures to prevent major accidents.
Geographic Information System GIS (Geographical Information System) is an emerging edge science developed in computer disciplines. It is an entered, stored, edited, queried, analyzed and output geographical graphics with modern computer graphics and database technology. The computer system of the attribute data is a comprehensive high-tech integration of geography, geometry, computer science and various application objects. Application of GIS participates in urban planning management, land resource management, surveying management, and development zone management. Quite mature, the GIS system is successfully applied to power, communication, gas, tap water, etc., More and more examples.
CityGIS1.0 is a desktop geographic information system platform with GIS features developed by Shanghai City Geographic Information System Development Co., Ltd.) from 1997 and has a desktop geographic information system platform with GIS features and independent copyright. It uses popular object-oriented design and encoding technology, the most significant feature is that graphical operation is speechless, practical. Especially for large data vectors, vector and images, the graphic image operation rate of CityGIS 1.0 is leading in the same product.
In response to the specific characteristics of gas pipe network safety, Application of City GIS 1.0 software development and establishing a urban pipe network GIS application system supported by GIS technology and computer technology, replacing the traditional management method management method, which can maximize gas Data maintenance, information query, alarm rescue, etc. of the pipe network. And provide high efficiency support for the improvement of the quality, management level, strengthening gas production scheduling and the ability to increase gas production.
The CITYGIS product developed by Shanghai City Geographic Information System Development Co., Ltd. can establish a gas pipe network GIS system to implement the following functions;
1. Graphics, Layer Operation 1) Basic functions such as graphics zoom, translation, roaming. 2) The layer calls, open, and off display. 3) Set the layer display ratio, and the control of the surface display content is dismissive. 4) Global Graphics Window and "Eagle Eye" function. 5) Multi-window simultaneously display. 6) Aviation remote sensing image and scan map superposition display function.
2. Displayed by business requirements 1) Position the display screen according to the management area, administrative region and other parameters. 2) Display line facilities in a special map based on attributes such as pipeline type, pipe diameter and so on. Differentiated as different linear patterns, thickness, colors, etc. 3) The pipeline facility is labeled in the figure facility in the figure in the figure in the figure. 4) Position the display area in accordance with the information of the road name, intersection, voltage regulator name, valve number, and graphics.
3. Query, statistics 1) Inquiries and statistics on the lines according to the parameters (or parameter ranges) of the pipe diameter, tubes, materials, pressure level. 2) Inquiries and statistics on the valve according to the number, type, size, useful limit, usage conditions (or parameter range). You can also query and statistical valve dynamic historical operations to master relevant business work processes. 3) Inquiries and statistics for queries (or parameter range) according to the number, type, pressure, performance, and usage conditions. 4) Position, query, and statistical pipeline facilities by information, sections and intersections. 5) According to the set spatial range (such as administrative regions, management areas, polygons, etc.) to statistics on the number of pipeline facilities, the length of the pipeline facilities. 6) In combination with spatial range conditions and attribute conditions to query and statistics on the facilities. The content of the facility query includes basic properties and related information, such as location diagrams, maintenance cards, monomer charts, photos, plan views, structural diagrams, and connected users, tubular units, and the like. 4. Emergency repair
1) The accident point positioning is quickly locked the accident location (or region) on the map based on the position information provided by the repair. Location information includes: road, intersection, user unit name.
2) Isolation of the "Map" system automatically search all the first level valves connected to the "Map", close these search valves, will ensure that the "drain point" is in the air-off state (ie, the isolation state).
3) The multi-level search system will automatically check the valve properties searched in the previous step. State, and further search the next level valve. This process continues until the foundable valve will completely isolate the "drain point".
4) Determine the influence range system to list the pressure regulating station in the isolation zone, and automatically query the user information associated with the user information and the tube unit of the pipeline facility, the scope of the air-proof range and the affected user , Prompts for flickering important users.
5) Send a notification system automatically prints all affected users, and prints or displays information and notices of relevant management, repair units.
6) 1: 500 Detailed diagram system Adjustable accident points 1: 500 Detailed pipeline facility maps are referred to the repair. According to the specific requirements, the system can print 1: 500 image of the "drain point" range, or directly draw these 1: 500 drawings directly, bringing the repair person to the scene.
7) The relevant information can superimpose the dangerous source, important units, fire systems, hospitals, etc. of the surrounding area of the accident.
5. Circular Topology Analysis ◆ The system can check connectivity between each facility. ◆ Select a valve in the figure, you can find the pipeline connected to it until it encounters the closed valve; ◆ Choose a pressure regulator in the figure, you can find the pipeline connected to it until it is closed The valve can be displayed in the jurisdiction of the pressure regulator; ◆ Select a pipeline in the figure to find lines, valves, and voltage regulators connected to it.
6. Splitting Scheduling In the premise of related communication technical conditions, the system can simulate access to SCADA real-time data, dynamic monitoring, and display the pressure status of each measurement point, and analyze the impact on the user based on empirical parameters and facility, thus Growing scheduling decision provides effective support.
7. User Management ◆ The management system of large, medium users (and user groups) will be established in the system. These users are connected to the facility system to construct the accident repair and the impact of the transmission schedule to the user. ◆ The system can query and statistically user information, such as the amount of gas, the user type, the degree of importance, the type of gas, etc. ◆ The system also provides user system maintenance tools to modify user properties; increase or cancel users; adjust the connection relationship between users and pressure regulating stations. 8. Maintenance Update Module System Provides a convenient operating tool to maintain update management in the system, maintain good data information. 1) Facility attribute modification, update 2) Increase the pipeline, valve, pressure regulating station and other facilities to increase the related properties after adding new facilities. The system automatically handles the topology connection relationship between the facility after the facility. 3) Delete pipelines, valves, pressure regulating stations and other facilities. The system prompts to delete the action and requires confirmation. The system automatically processes the topology connection between deletion facilities. The system simultaneously provides a facility dynamic maintenance schematic manufacturing function, which can directly add and modify all kinds of pipeline facilities.
9. Drawing Output 1) Print Output Facility Query, Statistics Report. 2) Press 1: 10,000 and 1: 5000 professional map template output facility map. 3) Print accidents. 4) Print the user list and various notices.
