Description

Technical Field

[0001] This invention relates to the field of computers, and more particularly to a microservice-based rain and flood consultation system. Background Technology

[0002] Currently, spatial consultation systems rely on Geographic Information System (GIS) functionality as the core tool for disaster analysis, including modules such as map editing, annotation, and spatial analysis. However, the GIS functions of these systems are general-purpose and applicable to most consultation scenarios. They lack specialized disaster analysis capabilities when dealing with specific disasters. The Storm Water Management Model (SWMM), a mature and widely used hydrological and hydrodynamic model, is a traditional standalone client program. Its deployment is cumbersome, it struggles to exchange data with external applications, and it cannot visualize stormwater simulation results on maps. Furthermore, current spatial consultation systems are built on WebGIS, making them web-oriented applications, which hinders the integration of the SWMM model with the spatial consultation system.

It provides a new platform for disaster relief personnel to discuss the rainstorm and flood situation and development trends online, greatly improving the efficiency of flood control and rescue decision-making and responding to the damage of rainstorm and flood disasters more scientifically and accurately.

[0059] Furthermore, the stormwater simulation calculation module includes a stormwater and flood management model file management component and an online real-time simulation calculation component;

[0060] The storm flood management model file management component is used to generate and manage the input and output files of the storm flood management model;

[0063] Furthermore, the online real-time simulation calculation component reads the input file of the Rainstorm Flood Management Model (SWMM) provided by the Rainstorm Flood Management Model (SWMM) file management component, and calls the dynamic link library of the Rainstorm Flood Management Model (SWMM) according to the input file to perform the Rainstorm Flood Management Model (SWMM) calculation and generate the output file.

[0064] In this embodiment of the invention, the input and output files of the rainstorm and flood management model are generated and managed by the rainstorm and flood management model file management component.

[0068] The simulation output file structure parsing component is also used to determine the parsing strategy of the output file output by the rainstorm and flood management model based on the file format and parameter definition of the simulation results.

[0069] Specifically, the Storm Flood Management Model (SWMM) object management component creates and saves computational objects for the SWMM. In one embodiment, the computational objects include sub-catchments, pipelines, and nodes. Therefore, it can be understood that the Storm Flood Management Model (SWMM) object management component creates and saves the sub-catchments, pipelines, and nodes for the SWMM.

[0070] Furthermore, the simulation output file structure parsing component extracts the stormwater simulation results from the sub-catchments, pipelines, and nodes created and saved by the stormwater and flood management model (SWMM) object management component.

[0071] Furthermore, the simulation output file structure parsing component determines the parsing strategy for the output files output by the stormwater and flood management model (SWMM) simulation results based on the file format and parameter definitions.

[0072] In this embodiment of the invention, the calculation objects of the rainstorm and flood management model are created and saved through the rainstorm and flood management model object management component, the rainstorm and flood simulation results are extracted through the simulation output file structure parsing component, and the parsing strategy of the output file output by the rainstorm and flood simulation calculation module is determined through the simulation output file structure parsing component.

[0073] Furthermore, the simulation result parsing module also includes a simulation result type conversion component and a simulation result management component;

[0074] The simulation result type conversion component is used to convert the data of the binary format output file parsed by the simulation output file structure parsing component into character data and numerical data;

[0075] The simulation result management component is used to manage the binary data extracted from the output file by the simulation output file structure parsing component, the binary data converted into character data and numerical data by the simulation result type conversion component, the character data and numerical data converted by the rainstorm and flood management model object management component, and the sub-catchments, pipelines and nodes of the rainstorm and flood management model generated by the rainstorm and flood management model object management component.

[0076] Specifically, the simulation result type conversion component converts the data in the binary format output file parsed by the simulation output file structure parsing component into character and numeric data.

[0079] Furthermore, the simulation result visualization module includes a first water level visualization component and a second water level visualization component;

[0080] The first water level visualization component is used to extract the attribute time series results of water depth and water volume of sub-catchment areas, pipelines and nodes during the simulation calculation of the rainstorm flood management model from the simulation result analysis module, and to display the extracted attribute time series results on the spatial consultation system in the form of a line graph.

[0081] The second water level visualization component is used to obtain geographical locations from the stormwater simulation calculation module and time series data of water level changes of nodes and pipelines from the simulation result analysis module through the visualization means of the geographic information system, combined with the three-dimensional models of nodes and pipelines, and to display the water level changes of nodes and pipelines in the calculation period using three-dimensional dynamic simulation.

[0082] Specifically, the first water level visualization component extracts the time series results of water depth and water volume attributes of sub-catchments, pipelines and nodes during the simulation calculation of the rainstorm flood management model (SWMM) from the simulation result analysis module, and displays the extracted attribute time series results on the spatial consultation system in the form of a line graph.

[0083] In one embodiment, one form of the first water level visualization component is a line graph-based water level visualization component. Therefore, it can be understood that the line graph-based water level visualization component extracts the time series results of the water depth and water volume attributes of sub-catchments, pipelines and nodes during the simulation calculation of the storm flood management model (SWMM) from the simulation result analysis module, and displays the extracted attribute time series results on the spatial consultation system in the form of a line graph.

[0084] Furthermore, the second water level visualization component uses the visualization methods of a geographic information system, combined with the three-dimensional models of nodes and pipelines, to obtain geographical locations from the stormwater simulation calculation module and time series data of water level changes of nodes and pipelines from the simulation result analysis module, and uses three-dimensional dynamic simulation to display the water level changes of nodes and pipelines within the calculation period.

[0085] In one embodiment, one form of the second water level visualization component is a water level visualization component based on a 3D geographic information system. Therefore, it can be understood that the water level visualization component based on a 3D geographic information system uses the visualization methods of the geographic information system, combined with the three-dimensional models of nodes and pipelines, to obtain the geographical location from the stormwater simulation calculation module and the time series data of water level changes of nodes and pipelines from the simulation result analysis module, and uses three-dimensional dynamic simulation to display the water level changes of nodes and pipelines within the calculation period.

[0086] This invention uses a first water level visualization component to display the extracted attribute time series results on a spatial consultation system, and a second water level visualization component to display the water level changes of nodes and pipelines within the calculation period. The calculation results are transformed into two-dimensional or three-dimensional geographic data. The spatial visualization and spatial analysis functions of the geographic information system are used to perform quantitative analysis of rainstorm disasters, intuitively reflecting the development trend of rainstorm disasters and providing support for disaster relief.

[0087] Furthermore, the simulation result visualization module also includes a seed point search component;

[0088] The seed point search component is used to obtain the geographical location information of the nodes from the stormwater simulation calculation module, and to search for seed nodes based on the D8 algorithm. It uses a disjoint-set data structure to record the search path during the seed search process, and performs a search process to make reasonable use of drainage nodes through search and merge operations to obtain a seed point set.

[0089] It should be noted that when urban drainage networks overflow, the water flow will begin to converge at lower-lying locations (i.e., water accumulation points). At the same time, there is a strong spatial correlation between urban drainage nodes. When water accumulation occurs, there will definitely be water overflowing from multiple drainage nodes flowing towards the same water accumulation point, which may cause the seed node search process to overlap.

[0090] Specifically, the seed point search component obtains the geographical location information of the nodes from the stormwater simulation calculation module, searches for seed nodes based on the D8 algorithm, uses a disjoint-set data structure to record the search path during the seed search process, and performs a search process to make reasonable use of drainage nodes through search and merge operations to obtain a seed point set.

[0091] In one embodiment, one form of the seed point search component is a seed point search component based on a disjoint-set data structure. Therefore, it can be understood as follows: the seed point search component based on a disjoint-set data structure obtains the geographical location information of the nodes from the stormwater simulation calculation module, searches for seed nodes based on the D8 algorithm, records the search path in the seed search process using a disjoint-set data structure, and performs a search process to make reasonable use of drainage nodes through search and merge operations to obtain a set of seed points.

[0092] This invention employs a seed point search component based on the D8 algorithm to search for seed nodes. Through search and merge operations, it achieves a search process that makes reasonable use of drainage nodes, thereby obtaining a set of seed points. The entire process reduces unnecessary search steps and improves search efficiency.

[0093] Furthermore, the simulation result visualization module also includes a water level calculation component and an inundation range visualization component;

[0094] The water level calculation component is used to obtain the overflow volume of each drainage node from the simulation result analysis module, obtain the water accumulation point of the drainage node from the seed point search component as the initial point for calculation, and obtain the water level of each water accumulation point by giving a maximum water level and a minimum water level, and search for the water level of each water accumulation point by binary search.

[0095] The flooding range visualization component uses a digital elevation model as terrain data, combines water accumulation nodes obtained from the seed point search component and water accumulation levels obtained from the water accumulation level calculation component, and employs a seed point spread algorithm to calculate the flooding range.

[0096] Specifically, the water level calculation component obtains the overflow volume of each drainage node from the simulation result analysis module, obtains the water accumulation point of the drainage node from the seed point search component as the initial point for calculation, and, given a maximum water level and a minimum water level, searches for the water level of each water accumulation point using a binary search.

[0097] Furthermore, the flooding range visualization component uses a digital elevation model as terrain data, combines water accumulation nodes obtained from the seed point search component and water accumulation levels obtained from the water accumulation level calculation component, and employs a seed point spread algorithm to calculate the flooding range.

[0098] In one embodiment, one form of the flood range visualization component is a flood range visualization component based on a digital elevation model. Therefore, it can be understood that: the flood range visualization component based on a digital elevation model uses a digital elevation model as terrain data, combines water accumulation nodes obtained from a seed point search component based on a disjoint set and water accumulation level obtained from a water accumulation level calculation component, and uses a seed point spread algorithm to calculate the flood range, supporting the use of a 3D geographic information system to realize the dynamic spread of the flood range on the map.

[0099] In this embodiment of the invention, the water level of each water accumulation point is obtained by searching through the water level calculation component, ensuring that the water volume is within a given range. The flood range is calculated by the flood range visualization component, thereby supporting the use of a 3D geographic information system to realize the dynamic spread of the flood range on the map.

[0100] Furthermore, the communication rules module includes a rainstorm and flood management model calculation communication rules component, a time series result extraction communication rules component, and an inundation range calculation communication rules component;

[0101] The rainstorm and flood management model calculation and communication rule component is used for the spatial consultation system to call the rainstorm and flood simulation calculation module and simulation result parsing module of the rainstorm and flood management model microservice;

[0102] The time series result extraction communication rule component is used for the spatial consultation system to make calls, and the rainstorm and flood management model microservice converts the simulation results of the rainstorm and flood management model into time series data;

[0103] The inundation range calculation communication rule component is used for invocation by the spatial consultation system, and the rainstorm and flood management model microservice performs inundation range calculation of the digital elevation model.

[0104] Specifically, the Rainstorm and Flood Management Model (SWMM) computational communication rule component is called by the spatial consultation system, and the Rainstorm and Flood Management Model (SWMM) microservice includes the rainstorm simulation calculation module and the simulation result parsing module.

[0105] Furthermore, the communication rule component for extracting time series results is called by the spatial consultation system, and the SWMM microservice of the rainstorm and flood management model converts the simulation results of the rainstorm and flood management model into time series data.

[0106] Furthermore, the inundation range calculation communication rule component is called by the spatial consultation system, and the rainstorm flood management model SWMM microservice executes the inundation range calculation of the digital elevation model.

[0107] This invention supports the use of a Rainstorm Flood Management Model (SWMM) computational communication rule component to enable spatial consultation systems to call the rainstorm simulation calculation module and simulation result parsing module. It also supports the use of a time series result extraction communication rule component to convert SWMM simulation results into time series data. Furthermore, it supports the use of an inundation range calculation communication rule component to enable spatial consultation systems to call SWMM microservices. This allows for data exchange and sharing via the Web, and enables online consultations using the SWMM through a spatial consultation system.

[0108] Furthermore, referring to Figure 2 , Figure 2 This is the second schematic diagram of the rain and flood consultation system based on microservices provided by the present invention.

[0109] The microservice-based rain and flood consultation system also includes a service health management module;

[0110] The service health management module is used to perform cluster deployment of the rainstorm and flood management model microservice, manage the online operation service information of the rainstorm and flood management model microservice, and manage the health status of the rainstorm and flood management model microservice.

[0111] Specifically, the Service Health Management module performs cluster deployment of the Rainstorm and Flood Management Model (SWMM) microservice, manages the online operation service information of the Rainstorm and Flood Management Model (SWMM) microservice, and manages the health status of the Rainstorm and Flood Management Model (SWMM) microservice.

[0112] In this embodiment of the invention, a service health management module is used to deploy a cluster of rainstorm and flood management model microservices and manage the health status of the rainstorm and flood management model microservices.

[0113] Furthermore, the service health management module includes service governance components and service monitoring components;

[0114] The service governance component is used to register its own service information with the registry center when the rainstorm and flood management model microservice starts up, and to request information on callable services from the registry center when the spatial consultation calls the rainstorm and flood management model microservice.

[0115] The service monitoring component is used to assign tasks to each investigator based on the workload, use a heartbeat mechanism to monitor the service in real time, and determine the dynamics of taking the service offline when it is unavailable.

[0116] Specifically, the service governance component registers its service information with the registry center when the SWMM (Flood and Rainstorm Management Model) microservice starts, and requests information about callable services from the registry center when the spatial consultation calls the SWMM microservice. This service information includes host IP (Internet Protocol), port, access protocol, etc.

[0117] Furthermore, the service monitoring component assigns tasks to each investigator based on workload, uses a heartbeat mechanism to monitor the service in real time, and dynamically determines when a service is unavailable and takes it offline.

[0118] In one embodiment, the service monitoring component distributes tasks evenly among each investigator.

[0119] In this embodiment of the invention, the service governance component requests information about callable services from the registry center, and the service monitoring component monitors the services in real time to prevent unhealthy services from being accessed.
