Description

Technical Field

[0001] The present invention belongs to the technical field of municipal pipe network layout, and in particular relates to an optimization method and system for overall monitoring layout of a municipal pipe network upstream of a sewage treatment plant. Background Art

[0002] Drainage pipe networks play an important role in ensuring the safe operation of cities. However, due to the strong concealment and wide distribution of drainage pipe network projects, their operation status is unclear and management is difficult. It is also difficult to analyze and diagnose problems such as mixed connections and inflow and infiltration. Online monitoring technology for drainage pipe networks can support quantitative diagnosis and analysis of drainage system problems and support intelligent management of drainage systems.

[0003] When monitoring the drainage network, if all drainage network nodes are monitored online, the operation dynamics of the drainage network can be fully understood, but this will result in a large number of nodes and excessively high monitoring costs. There is a node site selection method in the prior art, which is based on the basic theoretical basis and system algorithm of the average water age method and the coverage water volume method, combined with comprehensive indicators such as water volume and age and the operation status of the network, and then checked, analyzed and judged one by one. The representative nodes selected in the above method have a huge workload, and it is impossible to quickly obtain the addresses that need to be deployed. In addition, it is impossible to effectively monitor the branch lines that need to be monitored from a global perspective. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a method and system for optimizing the overall monitoring point layout of the municipal pipeline network upstream of the sewage treatment plant. Based on the upstream and downstream branches of the pipeline network, the pipe diameter and pipeline length are comprehensively considered, and the location of the branch lines is combined to improve the comprehensiveness and accuracy of monitoring. It is ensured that the deployed monitoring points can cover the key areas and nodes of the drainage network, and a scientific and effective monitoring point layout plan is designed to comprehensively reflect the operating status of the pipeline network.

[0005] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions: The first aspect of the present invention provides a method for optimizing the overall monitoring point layout of the municipal pipe network upstream of a sewage treatment plant.

[0006] The optimization method for the overall monitoring point layout of the municipal pipe network upstream of the sewage treatment plant includes the following steps: Obtain the topological structure of the drainage network to be monitored; Obtain the location of the sewage treatment plant, identify each drainage branch pipeline flowing to the sewage treatment plant, and determine the connection points of the drainage branch pipelines with different water flow directions; Calculate the length of each drainage branch pipeline, combine the pipe diameter and the pipeline length, set the first screening condition and the second screening condition, and screen out the drainage branch pipelines that need to be monitored from all drainage branch pipelines; In the drainage branch pipeline that needs to be monitored: For drainage branch pipelines with a diameter smaller than the first set value, the middle inspection well is selected as the location for installing the monitoring equipment; For drainage branch pipelines with a diameter greater than or equal to the first set value, determine whether there are branches on them with a diameter greater than or equal to the second set value. If so, the downstream inspection well of the branch confluence well with a diameter greater than or equal to the second set value will be used as the location for installing the monitoring equipment; if not, the middle inspection well of the drainage branch pipeline with a diameter greater than or equal to the first set value will be used as the location for installing the monitoring equipment.

[0007] The second aspect of the present invention provides an overall monitoring point optimization system for the municipal pipe network upstream of a sewage treatment plant.

[0008] The overall monitoring and distribution optimization system of the municipal pipe network upstream of the sewage treatment plant includes: The pipe network topology structure acquisition module is configured to: obtain the topology structure of the drainage pipe network to be monitored; The drainage branch pipeline determination module is configured to: obtain the location of the sewage treatment plant, determine each drainage branch pipeline flowing to the sewage treatment plant, and determine the connection points of the drainage branch pipelines with different water flow directions; The screening module is configured to: calculate the pipeline length of each drainage branch pipeline, combine the pipe diameter and the pipeline length, set the first screening condition and the second screening condition, and screen the drainage branch pipelines that need to be monitored from all the drainage branch pipelines; The point determination module is configured as follows: In the drainage branch pipeline to be monitored: For drainage branch pipelines with a diameter smaller than the first set value, the middle inspection well is selected as the location for installing the monitoring equipment; For drainage branch pipelines with a diameter greater than or equal to the first set value, determine whether there are branches on them with a diameter greater than or equal to the second set value. If so, the downstream inspection well of the branch confluence well with a diameter greater than or equal to the second set value will be used as the location for installing the monitoring equipment; if not, the middle inspection well of the drainage branch pipeline with a diameter greater than or equal to the first set value will be used as the location for installing the monitoring equipment. One or more of the above technical solutions have the following beneficial effects: The present invention provides a method and system for optimizing the overall monitoring point layout of the municipal pipeline network upstream of a sewage treatment plant. Firstly, based on the upstream and downstream branches of the pipeline network, the pipe diameter and the pipeline length are comprehensively considered, and the first screening condition and the second screening condition are set to screen out the drainage branch pipelines that need to be monitored from all the drainage branch pipelines; then, in combination with the pipe diameter and the position of the branch line, the specific positions of the detection points are planned for the screened drainage branch pipelines that need to be monitored, with the improvement of the comprehensiveness and accuracy of the monitoring as the starting point, ensuring that the deployed monitoring points can cover the key areas and nodes of the drainage pipeline network, and there is no need for calculation through complex algorithms, so that the monitoring point layout plan can be planned quickly, accurately and comprehensively, and the operation status of the pipeline network can be reflected scientifically, effectively and comprehensively.

[0009] The present invention combines the two aspects of pipe diameter and the location of branch lines. For drainage branch lines with a pipe diameter less than a first set value, the middle inspection well is selected as the location for installing monitoring equipment; for drainage branch lines with a pipe diameter greater than the first set value, it is further determined whether there is a branch with a pipe diameter greater than or equal to the second set value. If so, the downstream inspection well of the branch confluence well with a pipe diameter greater than or equal to the second set value is used as the location for installing monitoring equipment; if not, the middle inspection well of the drainage branch line with a pipe diameter greater than or equal to the first set value is used as the location for installing monitoring equipment. The above scheme effectively combines the branch lines that need to be monitored, and can effectively monitor the drainage network from a global perspective.

[0010] The first screening condition and the second screening condition set by the present invention respectively screen from two aspects of larger pipe diameter and shorter pipeline length and smaller pipe diameter and longer pipeline length, and the screening method is simple and reasonable.

[0011] When the present invention selects the middle inspection well as the location for installing the monitoring equipment, the total number of inspection wells is calculated by dividing the absolute value of 2 to obtain an inspection well ranking number: when the total number of inspection wells is an odd number, the monitoring equipment is arranged according to the calculated inspection well ranking number; when the total number of inspection wells is an even number, the monitoring equipment is arranged according to the next inspection well position of the calculated inspection well ranking number. The above scheme takes into account the odd and even number of the total number of inspection wells, and sets the locations according to different situations.

[0012] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0023] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0024] Embodiment 1 As described in the above background technology, under the constraint of economic cost, it is necessary to formulate a scientific and effective monitoring point layout plan based on monitoring needs and purposes, screen the most representative nodes, and obtain as comprehensive drainage network information as possible with as few monitoring points as possible, thereby forming a feasible monitoring point layout plan that takes into account both representativeness and economy.

[0025] In order to achieve the above purpose, the specific embodiment of the present invention calculates a scientific and effective monitoring point layout plan based on the upstream and downstream branches of the pipe network. The structure of the pipe network is deeply analyzed, mainly to improve the comprehensiveness and accuracy of monitoring, to determine the optimal location of the monitoring points, to ensure that the monitoring points can cover the key areas and nodes of the drainage pipe network, so as to fully reflect the operating status of the pipe network. Through scientific and reasonable point layout methods and advanced monitoring technology, effective management and maintenance of the drainage pipe network can be achieved, and the normal operation and sustainable development of the urban drainage system can be guaranteed.

[0026] The present embodiment discloses a method for optimizing the overall monitoring points of the municipal pipe network upstream of the sewage treatment plant, such as Figure 1 As shown, the following steps may be included: Obtain the topological structure of the drainage network to be monitored; Obtain the location of the sewage treatment plant, identify each drainage branch pipeline flowing to the sewage treatment plant, and determine the connection points of the drainage branch pipelines with different water flow directions; Calculate the length of each drainage branch pipeline, combine the pipe diameter and the pipeline length, set the first screening condition and the second screening condition, and screen out the drainage branch pipelines that need to be monitored from all drainage branch pipelines; In the drainage branch pipeline that needs to be monitored: For drainage branch pipelines with a diameter smaller than the first set value, the middle inspection well is selected as the location for installing the monitoring equipment; For drainage branch pipelines with a diameter greater than or equal to the first set value, determine whether there are branches on them with a diameter greater than or equal to the second set value. If so, the downstream inspection well of the branch confluence well with a diameter greater than or equal to the second set value will be used as the location for installing the monitoring equipment; if not, the middle inspection well of the drainage branch pipeline with a diameter greater than or equal to the first set value will be used as the location for installing the monitoring equipment.

[0027] In some embodiments, obtaining the topological structure of the drainage network to be monitored specifically includes: Perform topological checks on drainage branch pipelines in the drainage network, identify isolated pipelines and pipe points, and update data to ensure that drainage branch pipelines form a connected network; Check the attribute data of the drainage branch pipelines in the drainage network to identify abnormal conditions, including incomplete attribute information and out-of-range conditions, update the attribute data, and resolve attribute anomalies.

[0028] In some embodiments, the setting of the first screening condition and the second screening condition specifically includes: The first screening condition is: drainage branch pipelines with a pipe diameter greater than or equal to 1000mm and a pipeline length greater than 500m; The second screening condition is: drainage branch pipelines with a pipe diameter greater than or equal to 600mm and less than 1000mm, and a pipeline length greater than 1000m.

[0029] In some embodiments, for a drainage branch pipeline with a pipe diameter smaller than a first set value, a middle inspection well is selected as a location for installing monitoring equipment, specifically including: Obtain all inspection wells on the drainage branch pipelines whose diameters are smaller than the first set value, sort all inspection wells according to the flow direction of water, and assign a sorting sequence number to each inspection well; Calculate the total number of inspection wells divided by the absolute value of 2 to obtain an inspection well sorting number: When the total number of inspection wells is an odd number, the monitoring equipment shall be arranged according to the calculated inspection well sequence number; When the total number of inspection wells is an even number, the monitoring equipment shall be deployed at the next inspection well position according to the calculated inspection well sorting sequence number.

[0030] In some embodiments, the downstream inspection well of the branch confluence well with a pipe diameter greater than or equal to the second set value is used as the location for installing the monitoring equipment, specifically including: Determine the connection point between the branch whose pipe diameter is greater than or equal to the second set value and the drainage branch pipe whose pipe diameter is greater than or equal to the first set value, and use the inspection well at the connection point as the confluence well; Along the water flow direction of the drainage branch pipeline whose diameter is greater than or equal to the first set value, select the inspection well downstream of the confluence well as the location for installing the monitoring equipment.

[0031] In some embodiments, the middle inspection well of the drainage branch pipeline with a pipe diameter greater than or equal to the first set value is used as the location for installing the monitoring equipment, specifically including: Obtain all inspection wells on the drainage branch pipelines whose diameters are greater than the first set value, sort all inspection wells according to the flow direction of water, and assign a sorting sequence number to each inspection well; Calculate the total number of inspection wells divided by the absolute value of 2 to obtain an inspection well sorting number: When the total number of inspection wells is an odd number, the monitoring equipment shall be arranged according to the calculated inspection well sequence number; When the total number of inspection wells is an even number, the monitoring equipment shall be deployed at the next inspection well position according to the calculated inspection well sorting sequence number.

[0032] In some embodiments, the first setting value is 800 mm and the second setting value is 600 mm.

[0033] This embodiment first sets the first screening condition and the second screening condition based on the upstream and downstream branches of the pipeline network, taking into account the pipe diameter and the pipeline length, and screens out the drainage branch pipelines that need to be monitored from all the drainage branch pipelines; then, combining the two aspects of the pipe diameter and the location of the branch line, the specific locations of the detection points are planned for the screened drainage branch pipelines that need to be monitored, with the improvement of the comprehensiveness and accuracy of the monitoring as the starting point, ensuring that the deployed monitoring points can cover the key areas and nodes of the drainage network, and there is no need for complex algorithms to calculate, so as to achieve fast, accurate and comprehensive planning of the monitoring point plan, and scientifically, effectively and comprehensively reflect the operation status of the pipeline network.

[0034] This embodiment can quickly select the most representative nodes for point monitoring, make an overall unified plan, ensure representativeness and uniformity, and be conducive to a comprehensive grasp of the operating status of the entire pipeline network. It is of great significance for improving the operating efficiency of the urban drainage system, ensuring urban safety, and promoting sustainable development.

[0035] Next, the technical solution of this embodiment will be described in detail with reference to the accompanying drawings.

[0036] Overall, if Figure 1 As shown, the overall monitoring point optimization method for the municipal pipe network upstream of the sewage plant in this embodiment may include four steps: Drainage network topology inspection and correction; Starting from the sewage treatment plant, traverse all trunk pipe networks and branches to determine each drainage branch pipeline flowing to the sewage treatment plant; Based on the length of the drainage branch pipeline, filter the main pipeline network and branches that need to be deployed; Determine the inspection wells that need to be deployed.

[0037] Step 1: Check and correct the drainage network topology.

[0038] In this embodiment, the topological structure of the drainage network to be monitored is firstly obtained, and a topological check is performed on the drainage pipeline data therein.

[0039] Topological inspection mainly includes suspension inspection and connectivity analysis. Suspension inspection is implemented using a spatial scanning algorithm, and connectivity analysis is implemented using an adjacency matrix algorithm. Existing isolated points and isolated lines are identified, and after confirmation with management personnel, the data is updated to ensure that the drainage pipelines form a connected network.

[0040] The above-mentioned use of a space scanning algorithm to implement suspension inspection and an adjacency matrix algorithm to implement connectivity analysis to identify existing isolated points and isolated lines are prior arts and will not be elaborated here.

[0041] It also includes an inspection of the drainage pipeline attribute data, with the aim of identifying attribute anomalies, including incomplete attribute information and attribute information out of range, and then updating the attribute data to resolve attribute anomalies.

[0042] Update the attribute data, including solving the identified attribute anomalies, such as completing incomplete attribute information, re-assigning values ​​to out-of-range attribute information so that it is within the normal range, etc.

[0043] The above-mentioned incomplete attribute information and out-of-range attribute information may specifically include key attribute information such as pipeline diameter, burial depth, well depth, material, starting point pipe bottom elevation, and end point pipe bottom elevation.

[0044] By editing and updating the spatial data and attribute data of drainage pipelines, problems such as isolated points and lines, incomplete facility attributes, and attribute errors can be solved, ultimately forming a complete topology for the drainage network.

[0045] like Figure 2 As shown in the figure, the final topological structure diagram of the drainage network is obtained. Figure 2 It includes sewage treatment plants, sewage pumping stations, sewage pipe networks and inspection wells. There are multiple inspection wells on each sewage pipe network that flows to the sewage treatment plant, and sewage pumping stations are also set up at the connection between two sewage pipe networks. The arrows indicate the direction of water flow, DN indicates the pipe diameter, and the number after DN indicates the specific size of the pipe diameter in mm.

[0046] Step 2: Starting from the sewage treatment plant, traverse all trunk pipe networks and branches to determine each drainage branch pipeline flowing to the sewage treatment plant.

[0047] like Figure 3 The figure shows the drainage branch pipeline identification result. This embodiment takes the sewage treatment plant as the starting point, and traces each water branch flowing to the sewage treatment plant upstream along the water flow direction. The drainage pipelines with the same diameter are considered as one branch, thereby determining the drainage branch pipelines of this embodiment.

[0048] After determining the drainage branch pipelines, it is also necessary to determine the connection points of the drainage branch pipelines with different water flow directions until the connection points or terminal inspection wells of all pipelines with different water flow directions are found.

[0049] In addition, it also includes the classified storage of drainage branch pipelines with a diameter greater than 600mm in the drainage branch pipelines upstream of the sewage treatment plant according to the designated branches and pipe diameters.

[0050] Step 3: Based on the length of the drainage branch pipeline, filter the main pipeline network and branches that need to be deployed.

[0051] This step first requires calculating the length of each drainage branch pipeline, specifically by accumulating the length of all pipe sections in each drainage branch pipeline to obtain the total length of the drainage branch pipeline.

[0052] After obtaining the length of the drainage branch pipeline, in order to facilitate the screening of the drainage branch pipelines that need to be monitored, this embodiment sets a first screening condition and a second screening condition in combination with the pipe diameter and the pipeline length, and screens out the drainage branch pipelines that need to be monitored from all the drainage branch pipelines.

[0053] The first and second filter conditions are set as follows: The first screening condition is: drainage branch pipelines with a pipe diameter greater than or equal to 1000mm and a pipeline length greater than 500m; The second screening condition is: drainage branch pipelines with a pipe diameter greater than or equal to 600mm and less than 1000mm, and a pipeline length greater than 1000m.

[0054] Therefore, drainage branch pipelines with a diameter greater than or equal to 1000mm and a length greater than 500m and drainage branch pipelines with a diameter greater than or equal to 600mm and less than 1000mm and a length greater than 1000m were screened and retained. Figure 4 shown.

[0055] exist Figure 4 In the process, each filtered drainage branch pipeline is numbered, and the numbers are branch 1, branch 2, branch 3...branch 20.

[0056] Step 4: Determine the inspection wells that need to be deployed.

[0057] This step combines the pipe diameter and the location of the branch line in the drainage branch pipeline that needs to be monitored, effectively combines the branch line conditions that need to be monitored, and effectively monitors the drainage network from a global perspective: For drainage branch pipelines with a diameter smaller than the first set value, the middle inspection well is selected as the location for installing the monitoring equipment; For drainage branch pipelines with a diameter greater than or equal to the first set value, determine whether there are branches on them with a diameter greater than or equal to the second set value. If so, the downstream inspection well of the branch confluence well with a diameter greater than or equal to the second set value will be used as the location for installing the monitoring equipment; if not, the middle inspection well of the drainage branch pipeline with a diameter greater than or equal to the first set value will be used as the location for installing the monitoring equipment.

[0058] The first setting value is 800 mm, and the second setting value is 600 mm.

[0059] Further: (1) For drainage branch pipelines with a diameter less than 800 mm, select the middle inspection well as the location for installing monitoring equipment, such as Figure 5 As shown in the figure, the parity of the number of inspection wells is fully considered here. Specifically including: Obtain all inspection wells on the drainage branch pipeline with a pipe diameter less than 800 mm, sort all inspection wells according to the flow direction, and assign a sorting number to each inspection well; Calculate the total number of inspection wells divided by the absolute value of 2 to obtain an inspection well sorting number: When the total number of inspection wells is an odd number, the monitoring equipment shall be arranged according to the calculated inspection well sequence number; When the total number of inspection wells is an even number, the monitoring equipment shall be deployed at the next inspection well position according to the calculated inspection well sorting sequence number.

[0060] (2) For drainage branch pipelines with a diameter greater than or equal to 800 mm, determine whether there are branches with a diameter greater than or equal to 600 mm. If so, the downstream inspection well of the branch with a diameter greater than or equal to 600 mm shall be used as the location for installing monitoring equipment, including: Determine the connection point between the branch with a pipe diameter greater than or equal to 600mm and the drainage branch pipe with a pipe diameter greater than or equal to 800mm, and use the inspection well at the connection point as the confluence well; Along the water flow direction of the drainage branch pipeline with a diameter greater than or equal to 800mm, select the inspection well downstream of the confluence well as the location for installing the monitoring equipment.

[0061] (3) For drainage branch pipelines with a diameter greater than or equal to 800 mm, determine whether there are branches with a diameter greater than or equal to 600 mm. If not, the middle inspection well of the drainage branch pipeline with a diameter greater than or equal to 800 mm shall be used as the location for installing the monitoring equipment. Figure 5 As shown, specifically including: Obtain all inspection wells on drainage branch pipelines with a pipe diameter greater than or equal to 800 mm, sort all inspection wells according to the flow direction, and assign a sorting number to each inspection well; Calculate the total number of inspection wells divided by the absolute value of 2 to obtain an inspection well sorting number: When the total number of inspection wells is an odd number, the monitoring equipment shall be arranged according to the calculated inspection well sequence number; When the total number of inspection wells is an even number, the monitoring equipment shall be deployed at the next inspection well position according to the calculated inspection well sorting sequence number.

[0062] Therefore, based on the selected drainage pipeline branches that need to be monitored, for pipes with a diameter less than 800mm, each drainage branch should try to install monitoring equipment in the middle inspection well to represent the operation status of the branch: like Figure 5 As shown in the figure, the inspection well in the middle of the drainage branch pipeline is selected as the location for installing the monitoring equipment. First, the inspection wells on each drainage branch pipeline are obtained and sorted according to the specific flow direction, and the total number of inspection wells in each drainage branch pipeline is calculated (Σn); the inspection wells that need to be installed with monitoring equipment = ABS(Σn / 2), which is the absolute value of the sum of the inspection wells in each drainage branch divided by 2. Considering the parity of the total number of inspection wells, the points are set according to different situations.

[0063] exist Figure 5 In the above example, if the total number of inspection wells in the drainage branch pipeline is 4, the absolute value of 4 divided by 2 is calculated to be 2, and the next inspection well position after the inspection well with the inspection well sequence number 2 is selected to deploy the monitoring equipment; If the total number of inspection wells in the drainage branch pipeline is 5, then the absolute value of 5 divided by 2 is 3. At this time, directly select the inspection well with the inspection well sequence number 3 to deploy the monitoring equipment.

[0064] like Figure 6 As shown, in the selected drainage branch pipeline that needs to be monitored: For drainage branch pipelines with a diameter greater than or equal to 800mm, and branches with a diameter greater than or equal to 600mm, monitoring equipment shall be installed in the inspection well downstream of the confluence well of the branches with a diameter greater than or equal to 600mm; For drainage branch pipelines with a diameter greater than or equal to 800mm, and there are no branches with a diameter greater than or equal to 600mm, refer to the branches with a diameter less than 800mm and select the middle inspection well of the drainage branch pipeline with a diameter greater than 800mm to install the monitoring equipment.

[0065] The embodiment of the present invention effectively combines the branch lines that need to be monitored, and can effectively monitor the drainage network from a global perspective.

[0066] Embodiment 2 This embodiment discloses a system for optimizing the overall monitoring points of the municipal pipe network upstream of a sewage treatment plant.

[0071] The analysis module is used to analyze the sewage plant that needs to be analyzed based on the input.
