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.
In the prior art, for the rush repair of urban fuel pipe network, mostly, manual mode is adopted, gas supply is stopped through professional guidance, then professional maintenance personnel carry out the emergency maintenance of gas pipeline under safety control, temporary measures such as temporary plugging, repairing leakage and the like can be adopted to ensure pipeline stability, but this mode may lead to insufficient accuracy degree of rush repair or occurrence of the condition of rush repair lag.
In order to overcome the technical problems, the application discloses a method, a device, equipment and a medium for generating a rush-repair scheme based on an urban fuel pipe network, which can directly generate a corresponding rush-repair scheme based on a damaged area of the urban fuel pipe network, and effectively improve the rush-repair efficiency.
Referring to fig. 1, the embodiment of the invention discloses a method for generating a rush-repair scheme based on an urban fuel pipe network, which is applied to an urban fuel pipe network system and comprises the following steps:
and S11, constructing an undirected topology map corresponding to the urban fuel pipe network based on the point table data and the line table data, and determining a damaged area of the pipeline and a target valve corresponding to the damaged area of the pipeline based on the undirected topology map so as to generate a first emergency scheme according to the damaged area of the pipeline and the target valve.
In this embodiment, the source of the network topology data is various, including but not limited to: an analyzer (chromatograph, etc.), a flowmeter (turbine, ultrasonic wave, millimeter wave), a bromine adding meter, a sensor, equipment (pressure maintaining, pressure remote transmission, gas internet of things), etc., and is generally composed of a point table and a line table, wherein the point table represents various types of nodes in the topology, including attributes of nodes ID (Identity document), position names, types, coordinates, materials, etc., and the line table represents a pipeline connecting the nodes, including attributes of pipeline ID, pipe length, pipe diameter, wall thickness, coordinates, inflow end points, outflow end points, etc. All attributes of the point table and the line table should have integrity while their ID identification and spatial coordinate location are unique. Therefore, an undirected topology map corresponding to the urban fuel pipe network can be constructed according to preset point table data and line table data, further, after the undirected topology map is constructed, the undirected topology map can be segmented, the segmented undirected topology map is traversed, further, a damaged area of a pipeline and a valve corresponding to the damaged area of the pipeline are determined, and further, a first emergency scheme for closing the target valve is generated according to the damaged area of the pipeline and the corresponding valve.
And step S12, determining the pipe storage time corresponding to the damaged area of the pipeline based on transient simulation so as to generate a second emergency scheme according to the damaged area of the pipeline and the pipe storage time.
In this embodiment, the time when the pipeline is damaged may be determined, and the pressure data and the flow data of the preset time threshold before the damaged time are read from the database corresponding to the urban fuel pipe network, and it should be noted that the preset time threshold may be set by itself according to the user requirement, which is not limited in this embodiment. Further, a topological graph corresponding to the damaged area of the pipeline can be determined from the undirected topological graph, the topological graph corresponding to the damaged area of the pipeline is pushed to a preset transient solver, so that iterative computation is performed on the basis of pressure data and flow data of the topological graph corresponding to the damaged area of the pipeline by the transient solver, the time required by natural gas exhaustion in the urban fuel pipe network, namely the pipe storage time, is obtained, and further, a gas supplementing time node is determined according to the pipe storage time, so that a second emergency scheme for representing starting to execute gas supplementing is generated according to the gas supplementing time node.
And step S13, determining the lowest operating pressure value of the damaged area of the pipeline through steady-state simulation, and generating a third emergency scheme according to the lowest operating pressure value.
In this embodiment, in order to ensure that the fuel gas in the urban fuel pipe network is not exhausted, a corresponding air supplementing strategy is required to be formulated, specifically, the undirected topology graph may be assigned, a preset initial pressure value and the obtained assigned topology graph are pushed to a preset steady state solver, so as to obtain a pressure value to be determined through iterative computation of the preset steady state solver, and whether the pressure value to be determined is greater than a preset pressure judgment value, that is, a user actually uses a value, and the pressure value to be determined is required to be regulated according to a corresponding judgment result, if not, the pressure value to be determined is required to be increased according to a preset pressure lifting threshold until the pressure value to be determined is greater than a preset pressure judgment value, if the pressure value to be determined is greater than the preset pressure judgment value, the pressure value to be determined is directly determined as a lowest operating pressure value, and a third emergency scheme for characterizing and maintaining the lowest operating pressure value is generated based on the lowest operating pressure value. It should be noted that, the preset steady state solver in the present application is a solver for performing steady state simulation by a newton iteration method.
And step S14, generating a target emergency repair scheme based on the first emergency scheme, the second emergency scheme and the third emergency scheme.
In this embodiment, the first emergency scheme, the second emergency scheme and the third emergency scheme need to be integrated to generate the target emergency repair scheme, and it needs to be explained that the method for generating the emergency repair scheme based on the urban fuel pipe network further includes: pushing the target first-aid repair scheme to the front end of the urban fuel pipe network system so as to visually display the target first-aid repair scheme. That is, after the scheme is generated, the scheme can be directly pushed to the front end for visual display, so that relevant technicians can directly carry out rush repair according to the scheme. Therefore, the processing speed of the urban fuel network can be effectively improved, and the air supply of the user is ensured to be unaffected to the greatest extent.
It can be seen that, in this embodiment, firstly, an undirected topology map corresponding to an urban fuel pipe network is constructed based on point table data and line table data, a damaged area of a pipeline and a target valve corresponding to the damaged area of the pipeline are determined based on the undirected topology map, so as to generate a first emergency scheme according to the damaged area of the pipeline and the target valve, then, a pipe life corresponding to the damaged area of the pipeline is determined based on transient simulation, so as to generate a second emergency scheme according to the damaged area of the pipeline and the pipe life, and a lowest operation pressure value of the damaged area of the pipeline is determined through steady simulation, and a third emergency scheme is generated according to the lowest operation pressure value, and finally, a target emergency repair scheme is generated based on the first emergency scheme, the second emergency scheme and the third emergency scheme. Therefore, according to the method, an undirected topology map of the urban fuel pipe network is required to be constructed based on the point table data and the line table data, so that a damaged area of the urban fuel pipe network and a valve corresponding to the damaged area are determined based on the undirected topology map, and a first emergency scheme for closing the valve is generated based on the damaged area of the pipeline and the valve corresponding to the damaged area; further, a tube lifetime of the damaged area may be determined to initiate a second emergency regimen of air replenishment based on the tube lifetime characterization; further, a minimum operating pressure value for the damaged area of the pipe may be determined and a third emergency plan may be generated based on the minimum operating pressure value to characterize maintenance of the minimum operating pressure value. And the generated three emergency schemes can be integrated to generate a target emergency repair scheme, so that the corresponding emergency repair scheme can be generated only by knowing the mark or the position of the explosion pipe or the leakage pipe, and the emergency repair efficiency after the explosion or the leakage of the gas pipe is effectively improved.
Based on the foregoing embodiments, in the present application, it is necessary to generate a first emergency solution for closing a target valve based on a damaged area of a pipeline and the target valve, for which this embodiment describes in detail how to generate the first emergency repair solution, as shown in fig. 2, the embodiment of the present invention discloses a method for generating a first emergency repair solution based on an urban fuel pipe network, including:
and S21, reading point table data and line table data to construct an undirected topology graph based on the point table data and the line table data.
And S22, segmenting the undirected topological graph through a topological segmentation algorithm, and traversing the obtained segmented undirected topological graph to determine a damaged area of the pipeline and a target valve corresponding to the damaged area of the pipeline.
In this embodiment, the constructed undirected topology graph needs to be segmented by a topology segmentation algorithm, so as to determine a damaged area of a pipeline and a target valve corresponding to the damaged area of the pipeline, and the specific process is as follows: traversing the segmented undirected topological graph to determine whether a borderless pipeline area exists in the undirected topological graph, if so, eliminating the borderless pipeline area in the undirected topological graph to obtain a pipeline damaged area, and determining a target valve corresponding to the pipeline damaged area. That is, as shown in fig. 3, the undirected topology constructed according to the data of the point table and the data of the line table needs to be used as a dividing point, the topology is divided by using a topology dividing algorithm to obtain a plurality of isolated subgraphs, wherein the subgraphs are shown in fig. 4, the valves on the boundary in each isolated subgraph are the valves for blocking the affected area, the valves of the affected area are used as the judging basis of the boundary, when the valves of the affected area are closed, if the valves of the affected area are connected with the valves of the affected area, but the nodes not affected by the damaged pipeline are used as the undirected pipeline area, and the undirected pipeline area is deleted from the undirected topology, so that all the affected areas in the undirected topology, namely, the damaged pipeline area, are obtained. For example, as shown in the lower half of fig. 3, where the damaged pipeline is the pipeline connected between the node 5 and the node 3, the corresponding target valves are the valve 6, the valve 2 and the valve 7, and after the valves are closed, the damaged pipeline area shown in fig. 5 can be obtained, where the node user 8, the air source 1 and the user 9 may be connected with other pipelines or nodes, and are not affected by the damage of the connecting pipeline between the node 5 and the node 3. In order to obtain all affected areas in the undirected topological graph, traversing the undirected topological graph after segmentation, determining a corresponding pipeline damaged area by taking whether a boundary exists as a standard, if the traversed sub-graph exists, determining the area corresponding to the sub-graph as the pipeline damaged area, determining the valve corresponding to the sub-graph until all the sub-graphs are traversed, and determining all the affected areas and target valves corresponding to the affected areas.
Step S23, generating a first emergency plan for closing the target valve based on the damaged area of the pipe and the target valve.
In this embodiment, after determining all the damaged areas of the pipeline and the target valves corresponding to the damaged areas of the pipeline, all the valves may be closed based on the above areas and the valves to reduce the first emergency plan of the affected area, so that the urban fuel pipe network system closes all the valves involved in the plan by the system itself or notifying related personnel after receiving the first emergency plan to reduce the affected area.
And step S24, determining the pipe storage time corresponding to the damaged area of the pipeline based on transient simulation so as to generate a second emergency scheme according to the damaged area of the pipeline and the pipe storage time.
And S25, determining the lowest operating pressure value of the damaged area of the pipeline through steady-state simulation, and generating a third emergency scheme according to the lowest operating pressure value.
And step S26, generating a target emergency repair scheme based on the first emergency scheme, the second emergency scheme and the third emergency scheme.
It should be noted that, for the more detailed description of step S21, step S24 and step S25, reference may be made to the foregoing embodiments, and no further description is given here.
It can be seen that the undirected topology graph is segmented by a topology segmentation algorithm, and the obtained segmented undirected topology graph is traversed to determine a damaged area of the pipeline and a target valve corresponding to the damaged area of the pipeline, and then a first emergency scheme for closing the target valve is generated based on the damaged area of the pipeline and the target valve. In this way, a scheme for closing the respective valve may be generated at a first time after the respective damaged area is determined by the undirected topology map, so as to close the respective valve at the first time based on the generated scheme, thereby avoiding the diffusion of the affected area.
Based on the foregoing embodiment, it can be known that the pipe storage time corresponding to the damaged area of the pipeline can be determined based on transient simulation to generate the second emergency scheme for characterizing the start of executing the air supplement, so that the embodiment of the invention describes how to generate the two emergency repair schemes in detail, as shown in fig. 6, and the embodiment of the invention discloses a method for generating the emergency repair scheme based on the urban fuel pipe network, which comprises the following steps:
and S31, constructing an undirected topology map corresponding to the urban fuel pipe network based on the point table data and the line table data, and determining a damaged area of the pipeline and a target valve corresponding to the damaged area of the pipeline based on the undirected topology map so as to generate a first emergency scheme according to the damaged area of the pipeline and the target valve.
And S32, determining the damaged moment of the urban fuel pipe network, and reading pressure data and flow data of a preset time threshold before the damaged moment from a database corresponding to the urban fuel pipe network.
In this embodiment, the pressure data and the flow data of the pipeline are required for performing the transient simulation of the fuel gas, so in order to obtain the pressure data and the flow data of the pipeline, the pressure and the flow data of all nodes and the pipeline at the previous time of the pipeline explosion or leakage in the database corresponding to the urban fuel gas pipeline network need to be read, that is, the pressure and the flow data of all nodes and the pipeline at the preset time threshold before the pipeline explosion or leakage in the database corresponding to the urban fuel gas pipeline network need to be described, and the preset time threshold needs to be set according to the requirement, which is not limited in this embodiment.
And step S33, determining a target topological graph corresponding to the damaged area of the pipeline from the undirected topological graph, and pushing the target topological graph to a preset transient solver.
In this embodiment, based on the foregoing embodiment, it may be known that the undirected topology map needs to be segmented to obtain a plurality of sub-graphs, and traversing the sub-graphs to determine the damaged area of the pipeline, where in this embodiment, the sub-graph corresponding to the damaged area of the pipeline may be used as the target topology map, and the target topology map may be pushed to a preset transient solver, so that the transient solver uses the target topology map.
And step S34, performing iterative computation through the preset transient solver based on the target topological graph, the pressure data and the flow data to obtain the pipe storage time corresponding to the damaged area of the pipeline.
In this embodiment, iterative computation is required to be performed by using a preset transient solver based on a target topological graph, pressure data and flow data, so as to obtain a pipe storage time corresponding to a damaged area of a pipeline, and the specific process is as follows: assigning the pressure data and the flow data to boundary points of the target topological graph to obtain an assigned topological graph; pushing preset gas quantity assignment data to a preset transient solver, and performing iterative calculation through the preset transient solver based on the preset gas quantity assignment data and the assignment topological graph to obtain pipe storage time corresponding to the damaged area of the pipeline. That is, the topology map may be assigned by the pressure data and the flow data determined in the foregoing embodiments, the pressure data and the flow data may be assigned to the boundary points of the topology map to obtain an assigned topology map, and then the preset gas amount assignment data may be pushed to a preset transient solver, so that the transient solver performs iterative operation, and further determines the time required for characterizing the exhaustion of the natural gas in the urban fuel pipe network, that is, the pipe storage time corresponding to the damaged area of the pipe. It should be noted that, the preset transient solver in the present application is a solver for performing transient simulation based on the newton iteration method and a time step set by a user based on the user's own needs.
And step S35, determining an air supplementing time node based on the pipe storage time so as to generate a second emergency scheme representing the start of executing air supplementing based on the air supplementing time node.
In this embodiment, in order to avoid the exhaustion of the fuel gas in the urban fuel pipe network, the air needs to be supplemented before the exhaustion of the fuel gas, and since the time required for the exhaustion of the fuel gas, that is, the pipe storage time, has already been determined, a time node, that is, the air supplementing time node, may be set according to the pipe storage time, so as to generate a second emergency scheme for starting the air supplementing before the pipe storage time reaches the air supplementing time node. The air supply strategy used in the present application is an LNG air supply strategy.
And step S36, determining the lowest operating pressure value of the damaged area of the pipeline through steady-state simulation, and generating a third emergency scheme according to the lowest operating pressure value.
And step S37, generating a target emergency repair scheme based on the first emergency scheme, the second emergency scheme and the third emergency scheme.
It should be noted that, for the more detailed description of step S31, step S36 and step S37, reference may be made to the foregoing embodiments, and no further description is given here.
Therefore, in this embodiment, the damaged moment of the urban fuel pipe network can be determined, the pressure data and the flow data of the preset time threshold before the damaged moment are read in the database, then the target topological graph corresponding to the damaged area of the pipeline is determined from the undirected topological graph, the target topological graph is pushed to the preset transient solver, iterative computation is performed by the preset transient solver based on the target topological graph, the pressure data and the flow data, so as to obtain the pipe storage time corresponding to the damaged area of the pipeline, finally the air supplementing time node is determined based on the pipe storage time, and a second emergency scheme for representing to start executing air supplementing is generated based on the air supplementing time node. Therefore, the air supplementing can be ensured before the fuel gas is exhausted, and the use experience of a user is effectively improved.
Based on the foregoing embodiment, it can be known that the lowest operating pressure value of the damaged area of the pipeline can be determined based on steady-state simulation, and then the air supplementing is performed based on the lowest operating pressure value, and then the third emergency repair scheme is generated based on the lowest operating pressure value.
And S41, constructing an undirected topology map corresponding to the urban fuel pipe network based on the point table data and the line table data, and determining a damaged area of the pipeline and a target valve corresponding to the damaged area of the pipeline based on the undirected topology map so as to generate a first emergency scheme according to the damaged area of the pipeline and the target valve.
And step S42, determining the pipe storage time corresponding to the damaged area of the pipeline based on transient simulation so as to generate a second emergency scheme according to the damaged area of the pipeline and the pipe storage time.
And step S43, pushing the preset initial pressure value and the assignment topological graph to a preset steady state solver, and performing iterative computation based on the preset initial pressure value and the assignment topological graph through the preset steady state solver to obtain the pressure value to be determined.
In this embodiment, it should be noted that, the gas steady state solution simulation is an engineering simulation method, which is used to simulate the behavior of the gas system under the steady operation condition, unlike the transient simulation, the steady state simulation focuses on the behavior of the system after the system reaches the steady state, which is the long-time operation of the system. Therefore, the steady state solver may be used to determine the minimum operating pressure of the LNG make-up, and in order to determine the minimum operating pressure, the preset initial pressure value and the assignment topology determined in the foregoing embodiment may be pushed to the preset steady state solver, so that the steady state solver performs an iterative operation to generate the pressure value to be determined. The preset initial pressure value is an initial pressure value set by a user in the urban fuel pipe network system, and can be directly obtained from the urban fuel pipe network system after the user finishes setting. It should be further noted that, the iterative operation in the present application refers to a loop operation, and the process of obtaining the pressure value to be determined through specific iteration may refer to step S45.
And S44, judging whether the pressure value to be determined is larger than a preset pressure judgment value.
In this embodiment, since the pressure value generated by the steady state solver also needs to be determined by conditional judgment to determine whether the pressure value can be put into use, it is required to determine whether the pressure value to be determined is greater than a preset pressure judgment value.
And step S45, if not, the preset initial pressure value is increased based on a preset pressure increasing threshold value, and the step is skipped to push the preset initial pressure value and the assignment topological graph to a preset steady state solver so as to perform iterative calculation based on the preset initial pressure value and the assignment topological graph through the preset steady state solver, thereby obtaining the pressure value to be determined.
In this embodiment, if the pressure value to be determined is not greater than the preset pressure judgment value, the step of supplementing air by using the current pressure value to be determined may result in insufficient air supply, so that a new pressure value to be determined needs to be regenerated, specifically, the preset initial pressure value may be increased according to a preset pressure increase threshold, for example, the initial pressure value is increased by 2%, and then the preset initial pressure value and the assignment topology graph are pushed to a preset steady state solver, so that iterative calculation is performed by the preset steady state solver based on the preset initial pressure value and the assignment topology graph, so as to obtain the pressure value to be determined, so that iteration is performed by using the new initial pressure value, and the pressure value to be determined is regenerated until the generated pressure value to be determined is greater than the preset pressure judgment value.
And step S46, if yes, determining the pressure value to be determined as a lowest operating pressure value, and generating a third emergency scheme for representing maintaining the lowest operating pressure value based on the lowest operating pressure value.
In this embodiment, if the generated pressure value to be determined is greater than the preset pressure judgment value, the pressure value to be determined may be directly determined as the lowest operating pressure value, and a third emergency plan for characterizing maintenance of the lowest operating pressure value may be generated based on the lowest operating pressure value.
And step S47, generating a target emergency repair scheme based on the first emergency scheme, the second emergency scheme and the third emergency scheme.
It should be noted that, for the more detailed description of step S41, step S42 and step S47, reference may be made to the foregoing embodiments, and no further description is given here.
Therefore, in this embodiment, the preset initial pressure value and the assignment topology map may be pushed to the preset steady state solver, so that iterative computation is performed by the preset steady state solver based on the preset initial pressure value and the assignment topology map to obtain a pressure value to be determined, then whether the pressure value to be determined is judged, if the pressure value to be determined meets the condition, air supplementing may be performed based on the pressure value to be determined, and if the pressure value to be determined cannot meet the condition, the preset initial pressure value needs to be adjusted to perform a new iteration, and the pressure value to be determined is regenerated until the generated pressure value to be determined meets the condition. Therefore, the air supplementing can be ensured according to the minimum pressure actually required by the user, and the waste of resources is avoided.
