Background

The urban gas pipe network, the pipeline and the auxiliary facilities have strong concealment and high safety, and meanwhile, the pipe network terminal is connected with tens of thousands of nodes such as gas sources, users, voltage regulating stations, valve wells, plugs, ball valves and the like, so that the urban gas pipe network is huge and complex; with the wide application of the geographic information system GIS (Geographic Information Systems, geographic information system) in the urban gas field, the complex topological structure causes certain deviation between pipe network and pipeline data and real GIS data, thereby not only affecting the accurate simulation calculation of the urban gas pipe network, but also affecting the urban gas pipe network simulation and the integrity management of the pipeline, and preventing the process of intelligent urban treatment; in the prior art, currently, a gas company adopts an EXCEL form and combines a manual verification mode to screen the data of a point form and a line form, then a professional further designs a treatment mode for dirty data, and finally the inspection result is uniformly processed by using the EXCEL. The topology is checked using the QGIS (Quantum GIS) system to import GIS data. In the prior art, by importing urban pipe network topology data into a QGIS system, the problems related to the pipeline and the nodes can be roughly seen. However, for manual inspection, when the data volume is huge, the miss rate and the error rate of the manual inspection are greatly improved; when the redundancy of the abnormal data is too high, all redundancy conditions are difficult to be checked manually; the manual inspection is long in time consumption and high in cost, and the current requirements on different urban topologies are difficult to meet; the time division of the same area is not clear when a plurality of persons cooperate to treat the same area, and more repeated inspection situations occur. For inspection by using a QGIS system, only the outline of a certain area topology and the connection between dotted lines can be visualized, and the situation of isolation and point missing in the topology can not be intuitively reflected; a list of questions in the topology data cannot be listed.

In summary, how to automatically check pipeline data and node data in urban gas pipeline network topology data so that the pipeline network topology data is more similar to real GIS data is a technical problem to be solved in the field.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The urban gas pipe network, the pipeline and the auxiliary facilities have strong concealment and high safety, and meanwhile, the pipe network terminal is connected with tens of thousands of nodes such as gas sources, users, voltage regulating stations, valve wells, plugs, ball valves and the like, so that the urban gas pipe network is huge and complex; with the wide application of the geographic information system GIS in the urban gas field, the complex topological structure causes certain deviation between pipe network and pipeline data and real GIS data, which not only affects the accurate simulation calculation of the urban gas pipe network, but also affects the urban gas pipe network simulation and the integrity management of the pipeline, thus preventing the process of intelligent urban management; in the prior art, currently, a gas company adopts an EXCEL form and combines a manual verification mode to screen the data of a point form and a line form, then a professional further designs a treatment mode for dirty data, and finally the inspection result is uniformly processed by using the EXCEL. The QGIS system is used to import GIS data to check topology. In the prior art, by importing urban pipe network topology data into a QGIS system, the problems related to the pipeline and the nodes can be roughly seen. However, for manual inspection, when the data volume is huge, the miss rate and the error rate of the manual inspection are greatly improved; when the redundancy of the abnormal data is too high, all redundancy conditions are difficult to be checked manually; the manual inspection is long in time consumption and high in cost, and the current requirements on different urban topologies are difficult to meet; the time division of the same area is not clear when a plurality of persons cooperate to treat the same area, and more repeated inspection situations occur. For inspection by using a QGIS system, only the outline of a certain area topology and the connection between dotted lines can be visualized, and the situation of isolation and point missing in the topology can not be intuitively reflected; a list of questions in the topology data cannot be listed.

Therefore, the invention provides a topology inspection scheme for the urban gas pipe network, which can realize the automatic inspection of pipeline data and node data in the topology data of the urban gas pipe network, so that the topology data of the pipe network is more similar to real GIS data.

Referring to fig. 1, the embodiment of the invention discloses a topology integrity checking method for an urban gas pipe network, which comprises the following steps:

step S11: and acquiring the pipe network topology of the target urban gas pipe network, and node data and pipeline data in the pipe network topology.

In this embodiment, a unique identifier, a node name, a node coordinate, and a node type of each node in the pipe network topology are obtained; and acquiring unique identification information, pipeline names, pipeline coordinates, pipeline inflow nodes and pipeline outflow nodes of each pipeline in the pipeline network topology. It may be understood that obtaining a pipe network topology of the target urban gas pipe network, that is, the pipe network topology is constructed for each node and each pipeline based on real GIS data of the target urban gas pipe network, where the node data and the pipeline data of each node and the pipeline may specifically include: each node unique identifier, node name, node coordinates, node type and node material; and attribute data such as unique identification information of each pipeline, pipeline names, pipeline coordinates, pipeline inflow nodes, pipeline outflow nodes, pipeline length, pipeline diameter, pipeline wall thickness and the like.

In this embodiment, the node data and the pipe data in the pipe network topology used for construction are obtained from a preset channel, where the preset channel specifically may include, but is not limited to: analyzer, flowmeter, bromine adding meter, sensor, equipment etc., wherein the flowmeter specifically can be: turbine flow meters, ultrasonic flow meters, millimeter wave flow meters, and the like, which are not particularly limited. The equipment can be pressure maintaining equipment for keeping the pressure inside the equipment stable, a pressure sensor for transmitting pressure signals in the equipment through a remote transmission technology, gas internet of things equipment in a gas transmission and distribution pipe network and the like.

In this embodiment, the nodes in the pipe network topology are specifically: the pipeline in the pipeline topology is specifically a pipeline between the nodes.

Step S12: and checking the node data, the pipeline data, the node data and the topological area constructed by the pipeline data in the pipe network topology according to preset topology checking conditions so as to respectively acquire isolated point data in the node data, defect data in the pipeline data, isolated pipeline data in the pipeline data and isolated area data in the topological area.

In this embodiment, the node data in the pipe network topology, the pipe inflow node and the pipe outflow node in the pipe data are inspected according to a preset node unique identifier inspection condition and a preset node coordinate inspection condition, so as to obtain isolated point data in the node data and defect data in the pipe data; it can be understood that the node data in the pipe network topology, the pipe inflow node and the pipe outflow node in the pipe data are inspected according to the preset node unique identification inspection condition and the preset node coordinate inspection condition, and specifically, each node in the node data, the pipe inflow node and the pipe outflow node in the pipe data are inspected respectively through the preset node unique identification inspection condition so as to obtain the isolated point data and the defect data in the node data. The isolated point data and the defect data acquired based on the preset node unique identification check condition are partial isolated point data and defect data. In addition, the part of isolated point data and the defect data need to be checked by utilizing a preset node coordinate checking condition to check the node data in the pipe network topology and the pipeline inflow node and the pipeline outflow node in the pipe network data so as to acquire the isolated point data and the defect data in the node data. It should be noted that, because the unique node identifiers of each node, the pipeline outflow node and the pipeline outflow node in the node data and the pipeline data and the node coordinates corresponding to each node are unique and can be in one-to-one correspondence with the terminal or the pipeline in the real data GIS data, the problems of isolated point data and inaccurate defect data missing detection and the like in the detection process can be avoided by the mode of carrying out double detection on the node data and the pipeline data by presetting the node unique identifier detection conditions and the preset node coordinate detection conditions. The outlier data is: the node data corresponding to the nodes which only exist in the node data but not exist in the pipeline inflow nodes or the pipeline outflow nodes in the pipeline data in the pipeline network topology are the isolated point data, which means that the condition that an air source, a user, a voltage regulating station or a common node is not connected through a pipeline occurs in the urban gas pipeline network data operation. The defect data are: the node data corresponding to the nodes which are not present in the node data but present in the pipeline inflow node or the pipeline outflow node in the pipeline data in the pipeline network topology are the defect data, which means that the condition that the end of the pipeline network is not provided with the nodes in the urban gas pipeline network data operation.

In this embodiment, before checking the node data in the pipe network topology, the pipe inflow node and the pipe outflow node in the pipe data according to the preset node unique identifier checking condition and the preset node coordinate checking condition to obtain the isolated point data in the node data and the defect data in the pipe data, the method further includes: generating point table data of the pipe network topology based on all the node data; generating line table data of the pipe network topology based on all the pipeline data; counting the pipeline inflow nodes and the pipeline outflow nodes of each pipeline in the line table data, generating a node unique identifier set of the line table data based on the node unique identifiers of the pipeline inflow nodes and the node unique identifiers of the pipeline outflow nodes to obtain a first preset node unique identifier set, and constructing preset node unique identifier checking conditions for checking the isolated point data in the node data based on the first preset node unique identifier set; generating a node unique identifier set of the point table data based on node unique identifiers of all nodes in the point table data to obtain a second preset node unique identifier set, and constructing preset node unique identifier checking conditions for checking the defect data in the pipeline data based on the second preset node unique identifier set; it can be appreciated that point table data of the pipe network topology is generated based on all the node data; and generating line table data of the pipe network topology based on all the pipeline data. Thus, node data and pipe data of each node and pipe are collected in a unified manner by performing dot-and line-tabulation on the node data and pipe data. And then counting the node unique identifiers of pipeline inflow nodes and pipeline outflow nodes of each pipeline in the line table data, generating a node unique identifier set of the line table data, and constructing preset node unique identifier check conditions for the isolated point data in the check point table data based on the node unique identifier set. Generating a node unique identification set of the point table data based on the node unique identifications of the nodes in the point table data, and then constructing preset node unique identification checking conditions for checking the defect data in the pipeline data based on the node unique identification set. It should be noted that the node unique identifications of the pipe inflow node and the pipe outflow node in the pipe data are determined by the respective node coordinates of the pipe inflow node and the pipe outflow node. The node coordinates of the pipeline inflow node and the pipeline outflow node of the pipeline are determined by splitting the pipeline coordinates of the pipeline, for example: the pipe coordinates of a certain pipe are expressed as: LINESTRING (13352755.4 4279141.9, 13353399.1 4279185.3), and the node coordinates of each of the pipe inflow node and the pipe outflow node obtained after splitting are expressed as: point1 (13352755.4 4279141.9), point2 (13353399.1 4279185.3).

In this embodiment, before checking the node data in the pipe network topology, the pipe inflow node and the pipe outflow node in the pipe data according to the preset node unique identifier checking condition and the preset node coordinate checking condition to obtain the isolated point data in the node data and the defect data in the pipe data, the method further includes: splicing the abscissa and the ordinate in the node coordinates of all the node data in the point table data to obtain the coordinate uniqueness mark of each node; generating a node coordinate unique identifier set based on the coordinate unique identifiers of the nodes, and constructing preset node coordinate inspection conditions for inspecting the defect data in the pipeline data based on the node coordinate unique identifier set; determining node coordinates corresponding to the pipeline inflow node and the pipeline outflow node respectively based on the pipeline coordinates of the pipelines in the pipeline data so as to determine unique identification of the pipeline coordinates of the pipelines; and generating a pipeline coordinate unique identifier set based on the pipeline coordinate unique identifiers of the pipelines, and constructing preset node coordinate checking conditions for checking the isolated point data in the node data based on the pipeline coordinate unique identifier set. It can be understood that the abscissa and the ordinate of the node coordinates of the node data in the point table data are spliced to obtain the coordinate unique identifier of each node in the point table. Generating a node coordinate unique identifier set based on the coordinate unique identifiers of the nodes, and constructing preset node coordinate inspection conditions for inspecting the defect data in the pipeline data based on the node coordinate unique identifier set. The specific flow of acquiring the node unique identification of each node in the point table is as follows: firstly, node coordinates of all nodes are obtained, the node coordinates of all nodes are determined according to real GIS data, and then x coordinates and y coordinates of the node coordinates are spliced to obtain a node with a coordinate uniqueness mark (xy_coordinate). The preset node coordinate checking condition for checking the independent points in the node data is also constructed in the above manner, wherein, as a pipeline simultaneously has a pipeline inflow node and a pipeline outflow node, on the basis of the respective abscissa and ordinate splicing of the pipeline inflow node and the pipeline node outflow node, the coordinate uniqueness marks of the pipeline inflow node and the pipeline node outflow node are obtained as (xy_source) and (xy_target), and then the coordinates of the pipeline inflow node and the pipeline outflow node are spliced again to obtain (xy_st).

In this embodiment, checking an undirected pipeline topology constructed by the pipeline data in the pipe network topology according to a first preset pipeline connection number checking condition to obtain isolated pipeline data in the pipeline data; and checking the topology area in the pipe network topology according to a second preset pipeline connection quantity checking condition and a node type checking condition to acquire isolated area data in the topology area. It can be understood that the undirected pipeline topology is constructed according to the unique node identifiers corresponding to the pipeline inflow node and the pipeline outflow node of each pipeline in the pipeline data, and then each connected sub-graph in the undirected pipeline topology is checked, that is, the pipeline number of each connected sub-graph in the undirected pipeline topology is checked based on the first preset pipeline connection number checking condition, so as to obtain the isolated pipeline data. And checking the topological area in the pipeline topology according to the second preset pipeline connection quantity checking condition and the node type checking condition which are the air source node type and the non-air source node type so as to acquire isolated area data in the topological area.

In this embodiment, the node unique identifier of the node in the point table data is obtained through traversal, so as to obtain the unique identifier of the target node; judging whether the unique target node identifier exists in the first preset node unique identifier set, if not, marking the node corresponding to the unique target node identifier as isolated point data; traversing to obtain the coordinate uniqueness identification of each node in the point table data; judging whether the coordinate unique identifiers of all the nodes exist in the pipeline coordinate unique identifier set, and if not, marking the nodes corresponding to the coordinate unique identifiers of all the nodes as isolated point data. It will be appreciated that referring to fig. 2, the orphan point data inspection is to find abnormal nodes in the pipe network topology from the point of view of both the node unique identifier and the coordinate unique identifier based on the node data in the point table data and the pipe data corresponding to the pipe inflow node and the pipe outflow node of the pipe in the line table data. Specifically, before pipe network simulation is performed, all node ID sets are obtained from the point table, then all source end node IDs and target end node IDs at two ends of a pipe are combined into a new node ID set (st_gids) without repetition, and then a difference set is made by using the new node ID set obtained from the point table after the node ID set and the two end points of the pipe are combined to obtain node ID sets which cannot be corresponding to all node IDs and the two end points of the pipe, wherein the specific process of determining the node ID set which cannot be corresponding by making the difference set is as follows: and (3) through circularly acquiring each node ID in the point table, judging whether the acquired node IDs exist in the st_gids set, if not, reserving, and acquiring all isolated point data from the ID identification angle after traversing is finished. In order to acquire all isolated points from the coordinate angle, the x-coordinate and y-coordinate of all the nodes in the point table are needed to be spliced into the coordinate unique identifier (xy_coordinate) of each node, the coordinates of the two end points of the same-structure pipeline are also respectively spliced to obtain the coordinate unique identifier (xy_source) of the source end and the coordinate unique identifier (xy_target) of the target end, and the coordinate unique identifiers xy_source and xy_target of the two ends of each pipeline are combined into a new coordinate unique identifier set (xy_st) so as to facilitate the acquisition of the isolated points with abnormal coordinate angles in the subsequent process. And then, using all xy_coordinates in the point table and a new coordinate uniqueness identification set (xy_st) obtained by combining xy_source and xy_target in the line table to make a difference set to obtain a coordinate uniqueness identification set which cannot be corresponding to the coordinates of the nodes and the coordinates of the two ends of the pipeline, specifically, judging whether each xy_coordinate exists in xy_st by circularly acquiring each xy_coordinate in the point table, if not, reserving, and acquiring the coordinate uniqueness identification set which cannot be corresponding after the circulation is finished. Based on the obtained coordinate uniqueness identification set which cannot be corresponding, all the matched node ID identifications are obtained from the point table, and finally all the node ID identifications obtained from the ID and coordinate angles are combined to obtain an isolated point inspection list, and meanwhile, the isolated point inspection list is stored, so that a user can conveniently perform program automation or manual operation on the network topology based on the isolated point inspection result to delete nodes without type attributes and add pipelines to the nodes with the type attributes. It should be noted that, in the process of performing the inspection of the isolated point data, the unique identifier of the target node is a node ID, that is, the node ID data of the node to be inspected, the first preset node unique identifier set is a st_gids set, that is, a non-repeated node unique identifier set of the pipe inflow node and the pipe outflow node of each pipe in the line table data, the coordinate unique identifier is xy_coordinate, that is, the node coordinate data of the node to be inspected, the pipe coordinate unique identifier set is xy_st, that is, a non-repeated pipe coordinate unique identifier set of the pipe inflow node and the pipe outflow node of each pipe in the line table data.

In this embodiment, the pipeline coordinates of each pipeline in the line table data are obtained through traversal, and node unique identifiers corresponding to the pipeline inflow nodes and the pipeline outflow nodes of the corresponding pipelines are obtained based on the pipeline coordinates, so as to obtain the pipeline node unique identifiers; judging whether the unique identifier of the pipeline node exists in the second preset node unique identifier set, if not, marking the pipeline inflow node and/or the pipeline outflow node corresponding to the unique identifier of the pipeline node as defect data; traversing to obtain the unique identification of the pipeline coordinates of each pipeline in the line table data; judging whether the pipeline coordinate unique identifiers of the pipelines exist in the node coordinate unique identifier set, and if not, marking the pipeline inflow nodes and/or the pipeline outflow nodes corresponding to the pipeline coordinate unique identifiers of the pipelines as defect data. It will be understood that, referring to fig. 3, before performing pipe network simulation, two end points of the pipe, that is, all source end node IDs and target end node IDs, are combined into a new non-repeated node ID set (st_gids), then all node ID sets in the point table data are acquired, and then a difference set is made between the combined node ID set (st_gids) and the node ID set acquired from the point table data to obtain node IDs of all two end point IDs of the pipe in the pipe data, specifically, each node ID in the st_gids is acquired circularly, whether the node IDs exist in the point table ID set is judged, if the node IDs do not exist, the node IDs are reserved, and then all the pipe IDs are found out based on the node IDs which cannot correspond, that is, any end of the two end points of the pipe is the node ID. In order to acquire all the defect data from the coordinate angle, the coordinates of the two end points of the pipeline are also respectively spliced to obtain the coordinate unique identifier (xy_source) of the source end and the coordinate unique identifier (xy_target) of the target end, the coordinate unique identifiers xy_source and xy_target of the two end points of each pipeline are combined into a new coordinate unique identifier set (xy_st), and the x coordinate and y coordinate of all the nodes in the same-point table are also spliced to the coordinate unique identifier (xy_coordinate) of each node so as to facilitate the acquisition of the isolated point with abnormal coordinate angle in the subsequent step. Next, a new coordinate uniqueness identification set (xy_st) obtained by combining xy_source and xy_target in line table data and all xy_coordinates in a point table are used for making a difference set to obtain a coordinate uniqueness identification set which cannot be corresponding to the coordinates of two ends of a pipeline and the coordinates of a node, specifically, each xyoordinate in the coordinate uniqueness identification set is obtained through circulation, whether the xyoordinate exists in the point table or not is judged, and if not, the xyoordinate exists in the point table, the coordinate uniqueness identification set is reserved. And then, based on the acquired unique identifiers of the coordinates which cannot be corresponding, finding all the matched pipeline ID identifiers from the line table data, and finally merging all the pipeline ID identifiers obtained from the ID and coordinate angles. Therefore, an online defect checking list is obtained and stored, so that a user can conveniently add nodes and attributes to the nodes by program automation or manual work on topology data based on an online defect checking result.

Step S13: and generating an integrity check list aiming at the pipe network topology according to the isolated point data, the defect data, the isolated pipeline data and the isolated area data so as to finish the integrity check of the urban gas pipe network topology.

In this embodiment, an integrity checklist for pipe network topology is generated according to an isolated point checklist, an on-line defect checklist, isolated pipe data, and isolated area data, and specifically, an isolated check summary is performed on the ID identifiers of the nodes in the point table data, the ID identifiers of the two endpoints in the line table data, and the coordinates of the node points to obtain a node ID identifier list; performing deletion inspection on ID identifications and coordinates of two endpoints of the line table data and ID identifications and coordinates in the point table data to obtain an on-line defect pipeline ID identification list; acquiring a pipeline ID identification list of the non-air source endpoint based on ID identifications of two endpoints in the line table data and node types in the point table data; obtaining a pipeline ID identification list of an isolated area without a large air source, a pipeline ID identification list of an isolated area without a small air source, a pipeline ID identification list of an isolated area with a large air source and a pipeline ID identification list of an isolated area with a small air source according to ID identifications of two endpoints in line table data and node types in point table data; and integrating the identification list to obtain a pipeline topology integrity primary checking list, namely an integrity checking list. The detected problem list is more detailed, and the isolated points and the defects on the line are positioned more accurately, so that the authenticity of the network topology simulation is improved, templates are provided for GIS data management and inspection of various cities in the whole country, and the construction of the intelligent city network is accelerated.

Referring to fig. 4, an embodiment of the present invention discloses a method for checking isolated pipe data and isolated area data in a specific urban gas pipe network topology, and compared with the previous embodiment, the present embodiment further describes and optimizes a technical scheme. Specific:

step S21: and acquiring the pipe network topology of the target urban gas pipe network, and node data and pipeline data in the pipe network topology.

In step S21, the detailed processing procedure is referred to the above disclosed embodiments, and will not be described herein.

Step S22: counting the number of pipelines in each connected subgraph of the undirected pipeline topology; judging whether the number of the pipelines in each communication subgraph is smaller than a first preset pipeline connection number or not; if yes, acquiring the pipeline in the corresponding communication subgraph as a target pipeline.

In this embodiment, referring to fig. 5, since the isolated pipes are pipes in the area where the number of pipes on each connected sub-graph in the pipe network topology is less than 5 and the air source type node is not included, this represents a situation where a small number of areas without air source air supply occur in the data operation of the urban gas pipe network. And the isolated pipeline inspection is to find the number of abnormal pipelines in the pipeline network topology based on the ID identification information of the two ends of the pipeline in the line table data and the attribute data of the node type in the point table data. Specifically, before pipe network simulation is carried out, constructing an undirected pipeline topology through pipeline inflow node IDs and pipeline outflow node IDs at two ends of a pipeline, then counting the number of pipelines on each connected subgraph in the undirected pipeline topology, judging whether connected subgraphs smaller than 5 pipelines exist in the undirected pipeline topology, and acquiring the pipeline inflow node IDs and the pipeline outflow node IDs at two ends of all the pipelines based on all the pipeline IDs in an isolated pipeline for the connected subgraphs smaller than 5 pipelines; if the number of the pipelines in the connected subgraph is more than 5, no processing is performed. The first preset pipeline connection number is 5, and the target pipelines are all pipelines in the communication subgraph with the pipeline connection number smaller than 5.

Step S23: determining node types corresponding to the pipeline inflow node and the pipeline outflow node of the target pipeline based on the node unique identifiers corresponding to the pipeline inflow node and the pipeline outflow node of the target pipeline and the point table data; judging whether target pipeline nodes with the node type being an air source type exist in all pipeline inflow nodes and pipeline outflow nodes; if not, marking the target pipeline as isolated pipeline data.

In this embodiment, for each pipe inflow node ID and pipe outflow node ID obtained in an isolated pipe, that is, after obtaining a target pipe, node type information corresponding to a pipe inflow node and a pipe outflow node in the target pipe in point table data is found out through circulation, if a pipe inflow node or a pipe outflow node in the target pipe has a target pipe node of an air source type, no processing is performed, if a connected subgraph does not have a node of an air source type, all pipe ID lists in the isolated pipe are listed and stored, so that a user can conveniently perform program automation or manual deletion operation on topology data based on the result of inspection of the isolated pipe.

Step S24: constructing a topological area taking a unique line table identifier as an attribute and the unique node identifiers of the pipeline inflow node and the pipeline outflow node of the pipeline data as edges based on line table data; and labeling the region types of each topological region based on the second preset pipeline connection number and the node types of the pipeline nodes so as to acquire isolated region data in the topological region according to the labeling result of the topological region.

In this embodiment, referring to fig. 6, since the urban gas network is a relatively complete topology, each gas source will supply gas and air to each downstream area. Thus, there should be at least one air source in each island. The isolated area is an independent area with 100 as a dividing line for the number of pipelines on each connected subgraph in the pipe network topology and whether air source nodes are in the connected subgraphs or not, which represents the situation that a plurality of independent areas exist in the topology in the urban gas pipe network data operation. And the isolated area inspection is to find different and independent connected subgraphs in the pipe network topology based on ID identification information at two ends of a pipeline in the line table data and type attributes of nodes in the point table data. Specifically, before pipe network simulation, an undirected graph, namely a topological area, is constructed by taking a line table ID as an attribute and taking a pipeline inflow node ID and a pipeline outflow node ID as edges based on line table data. And counting the number of the air source nodes with all the node types in the point table data as the air source type and the pipelines of each connected subgraph in the topology based on the type attribute of the nodes in the point table data, and further dividing the conditions of the air source nodes and the pipeline number into the following cases:

And if the number of the pipelines of the connected subgraph in the topological area exceeds the second preset pipeline connection number and the target pipeline nodes of the air source type exist in the connected subgraph, marking the topological area as an isolated area with large air source. That is, if the number of the pipelines in the connected subgraph is greater than 100 and the gas source nodes are contained at the same time, the connected subgraph can be divided into isolated areas with large gas sources.

If the number of the pipelines of the connected subgraph in the topological area exceeds the second preset pipeline connection number and no target pipeline node of the air source type exists in the connected subgraph, marking the topological area as an isolated area without a large air source; that is, if the number of connected subgraphs is greater than 100 and no air source node is included, the connected subgraphs can be divided into isolated areas with large air source.

If the number of the pipelines of the connected subgraph in the topological area does not exceed the second preset pipeline connection number and the target pipeline nodes of the air source type exist in the connected subgraph, marking the topological area as an isolated area with small air source; that is, if the number of connected subgraphs is less than 100 and the connected subgraphs contain air source nodes, the connected subgraphs can be divided into isolated areas with small air sources.

And if the number of the pipelines of the connected subgraph in the topological area does not exceed the second preset pipeline connection number and no target pipeline node of the air source type exists in the connected subgraph, marking the topological area as an isolated area with no air source and small. That is, if the number of connected subgraphs is less than 100 and no air source node is included, it can be divided into isolated areas with small air source. It should be noted that the second preset number of pipe connections is 100. And then, respectively listing and storing pipeline ID lists of different isolated areas, so that a user can conveniently perform program automation or manual operation on GIS topology data based on the isolated area inspection result to add pipeline connected sub-areas.

Therefore, the pipeline topology is checked through whether the pipeline number and the node type are of the air source type or not, so that the inspection of the isolated pipeline and the isolated area is realized, and the problem that the isolated pipeline network is difficult to inspect due to data loss and abnormality in the GIS data treatment process is solved.

Referring to fig. 7, the embodiment of the invention also discloses a device for checking the topology integrity of the urban gas pipe network, which comprises:

the data acquisition module 11 is used for acquiring the pipe network topology of the target urban gas pipe network and node data and pipeline data in the pipe network topology;

the manifest generating module 13 is configured to generate an integrity check manifest for the network topology according to the isolated point data, the defect data, the isolated pipe data, and the isolated area data, so as to complete integrity check of the urban gas network topology.

Therefore, the application discloses obtaining the pipe network topology of the target urban gas pipe network, and node data and pipeline data in the pipe network topology; checking the node data, the pipeline data, the node data and the topological area constructed by the pipeline data in the pipe network topology according to preset topology checking conditions to respectively acquire isolated point data in the node data, defect data in the pipeline data, isolated pipeline data in the pipeline data and isolated area data in the topological area; and generating an integrity check list aiming at the pipe network topology according to the isolated point data, the defect data, the isolated pipeline data and the isolated area data so as to finish the integrity check of the urban gas pipe network topology. It can be seen that by checking node data, pipe data, and topology regions in the pipe network topology according to preset topology conditions, then, isolated point data in the node data, defect data in the pipe data, isolated pipe data in the pipe data, isolated region data in the topology regions, and the like can be obtained respectively, by positioning checking the whole aspect from the node to the pipe to the region in the pipe network topology, the miss probability can be reduced, repeated checking is avoided, and defect data, isolated point data, isolated pipe data, and isolated region data can be intuitively reflected, so as to generate an integrity check list of the pipe network topology.
