Description

Technical Field

[0001] This invention relates to the field of drainage network monitoring technology, and in particular to a method, apparatus, equipment, and storage medium for detecting drainage network indicators. Background Technology

[0002] With the development of urbanization, the operation and management of drainage pipe networks has become one of the important tasks of urban management. Indicators such as flow rate and water quality are important basic data for the operation and management of drainage pipe networks. However, due to the existence of siltation, drop, and backlog in drainage pipe networks, actual measurement is difficult. Commonly used monitoring equipment is difficult to reliably obtain effective data, and the testing equipment is costly and complicated to install, making it difficult to meet the needs of large-scale pipe network deployment.

[0003] Specifically, current conventional monitoring methods require the installation of dedicated monitoring equipment at all monitoring points to obtain data for a specific indicator. The larger the monitoring area, the more measuring equipment is needed, leading to higher procurement, installation, and maintenance costs. Furthermore, the space available for inspection wells for these devices is limited, and deploying too much equipment can disrupt daily inspections and maintenance of the drainage network. Therefore, the industry urgently needs an economical and stable solution for measuring drainage network indicators to optimize the existing conventional monitoring model. Summary of the Invention

[0004] In view of the above, the present invention aims to provide a method, apparatus, equipment and storage medium for detecting drainage network indicators, in order to solve the specific problems mentioned above.

[0005] The technical solution adopted in this invention is as follows:

[0006] In a first aspect, the present invention provides a method for detecting indicators of a drainage pipe network, comprising:

[0007] From the pre-defined complete monitoring area of ​​the drainage network, several independent monitoring sub-areas are separated, and each independent monitoring sub-area contains only the T-junction manifold;

[0008] Obtain the measured values ​​of the first monitoring index of the downstreamest pipeline in each independent monitoring sub-region and the measured values ​​of the second monitoring index of all pipelines in that sub-region;

[0009] Using the measured values ​​of the first and second monitoring indicators, the calculated values ​​of the first monitoring indicators on all pipelines in the sub-region except the most downstream pipeline are obtained successively in the direction from downstream to upstream.

[0010] In at least one possible implementation, the step of splitting into several independent monitoring sub-regions includes:

[0011] Retrieve non-TE-type manifold monitoring wells within the complete monitoring area;

[0012] Using the retrieved non-te-joint manifold detection wells as connecting manifold wells, the complete monitoring area is divided into several independent monitoring sub-areas containing only te-joint manifold wells. In the independent monitoring sub-areas containing connecting manifold wells, the two upstream branches of the connecting manifold wells are retained to be equivalent to te-joint manifold wells, and the remaining upstream branches of the connecting manifold wells are respectively equivalent to the downstream pipelines of the corresponding other independent monitoring sub-areas.

[0013] If no non-T-junction manifold detection well is found, the entire monitoring area is considered as an independent monitoring sub-area.

[0014] In at least one of the possible implementations, the method of successively obtaining the calculated value of the first monitoring indicator includes:

[0015] Starting from the first manifold at the downstream end of the independent monitoring sub-area, the measured values ​​of the first and second monitoring indicators of the downstream pipeline of the first manifold, as well as the measured values ​​of the second monitoring indicators of the two upstream branches of the first manifold, are used to obtain the calculated values ​​of the first monitoring indicators of each upstream branch corresponding to the first manifold.

[0016] The calculated value of the first monitoring index of an upstream branch and the measured value of the second monitoring index of the same upstream branch are equivalent to the measured value of the downstream pipeline of the corresponding second manifold. The calculation results of the first monitoring index of all pipelines in the independent monitoring sub-area are obtained by performing the above calculations one by one.

[0017] In at least one of the possible implementations, the location of the monitoring points of the first monitoring indicator and the second monitoring indicator is determined by setting the location based on a preset monitoring time dimension and in combination with at least one of the following factors: well spacing, well condition, pipeline and drainage status.

[0018] In at least one of the possible implementations, the first monitoring indicator is flow data and the second monitoring indicator is water quality data, or the first monitoring indicator is water quality data and the second monitoring indicator is flow data.

[0019] Secondly, the present invention provides a drainage pipe network index detection device, comprising:

[0020] The monitoring unit division module is used to divide the pre-defined complete monitoring area of ​​the drainage network into several independent monitoring sub-areas, and to ensure that each independent monitoring sub-area contains only the T-junction manifold.

[0021] The measured value acquisition module is used to acquire the measured value of the first monitoring index of the downstream pipeline in each independent monitoring sub-region and the measured value of the second monitoring index of all pipelines in that sub-region.

[0022] The monitoring index calculation module is used to calculate the first monitoring index value for all pipelines in the sub-region except the downstream pipeline by using the measured values ​​of the first and second monitoring indexes in the direction from downstream to upstream.

[0023] In at least one possible implementation, the step of splitting into several independent monitoring sub-regions includes:

[0024] The non-TEV junction well retrieval unit is used to retrieve non-TEV junction-type detection wells within the complete monitoring area;

[0025] The first sub-region setting unit is used to divide the complete monitoring area into several independent monitoring sub-regions that only contain tee manifolds, using the retrieved non-tee manifold detection wells as connecting manifolds; wherein, in the independent monitoring sub-regions containing connecting manifolds, the two upstream branches of the connecting manifolds are retained to be equivalent to tee manifolds, and the remaining upstream branches of the connecting manifolds are respectively equivalent to the downstream pipelines of the corresponding other independent monitoring sub-regions;

[0026] The second sub-region setting unit is used to treat the entire monitoring area as an independent monitoring sub-region if no non-T-junction flow-type detection well is found.

[0027] In at least one possible implementation, the monitoring indicator calculation module includes:

[0028] The initial calculation unit is used to start from the first manifold at the downstream end of the independent monitoring sub-area, and use the measured values ​​of the first and second monitoring indicators of the downstream pipeline of the first manifold, as well as the measured values ​​of the second monitoring indicators of the two upstream branches of the first manifold, to calculate the first monitoring indicator values ​​corresponding to each upstream branch of the first manifold.

[0029] The progressive calculation unit is used to calculate the first monitoring index of all pipelines in the independent monitoring sub-area by taking the calculated value of the first monitoring index of an upstream branch and the measured value of the second monitoring index of the same upstream branch as the measured value of the downstream pipeline of the corresponding second manifold.

[0030] Thirdly, the present invention provides a drainage pipe network index testing device, comprising:

[0031] One or more processors, a memory, and one or more computer programs, the memory being a non-volatile storage medium, wherein the one or more computer programs are stored in the memory, the one or more computer programs including instructions that, when executed by the device, cause the device to perform the method as described in the first aspect or any possible implementation thereof.

[0032] Fourthly, the present invention provides a non-transitory computer-readable storage medium for storing computer-readable instructions, which, when executed by a processor, cause the processor to perform the drainage network index detection method as described above.

[0033] The main design concept of this invention is to, compared to conventional monitoring methods, divide a pre-defined complete monitoring area of ​​the drainage network into several independent monitoring sub-areas, ensuring that each independent monitoring sub-area contains only T-junction manholes. Then, the measured values ​​of the first monitoring index for the downstream pipeline in each independent monitoring sub-area and the measured values ​​of the second monitoring index for all pipelines in that sub-area are obtained. Next, using the measured values ​​of the first and second monitoring indexes, the calculated values ​​of the first monitoring index for all pipelines in that sub-area, excluding the downstream pipeline, are successively calculated from downstream to upstream. This invention, by using preset monitoring indicators to progressively calculate upstream pipeline values, effectively avoids the influence of flow patterns. Therefore, when actually deploying the measuring equipment, it is only necessary to ensure the stability of the dual-indicator monitoring at the downstream end and the single-indicator monitoring of other branches, thus obtaining continuous and reliable monitoring index data for the entire network while significantly reducing costs. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0035] Figure 1 A flowchart illustrating the drainage network index detection method provided in this embodiment of the invention;

[0036] Figure 2 This is a schematic diagram of the drainage pipe network monitoring area division provided in an embodiment of the present invention;

[0037] Figure 3 This is a block diagram of a drainage network index detection device provided in an embodiment of the present invention. Detailed Implementation

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] This invention proposes an embodiment of a method for detecting indicators of drainage pipe networks, specifically, as follows: Figure 1 As shown, it includes:

[0040] Step S1: From the pre-defined complete monitoring area of ​​the drainage network, divide it into several independent monitoring sub-areas, and make each independent monitoring sub-area contain only the T-junction manifold;

[0041] Step S2: Obtain the measured values ​​of the first monitoring index of the downstream pipeline in each independent monitoring sub-region and the measured values ​​of the second monitoring index of all pipelines in that sub-region;

[0042] Step S3: Using the measured values ​​of the first monitoring index and the second monitoring index, calculate the first monitoring index values ​​for all pipelines in the sub-region except for the downstream pipeline in the direction from downstream to upstream.

[0043] To elaborate, drainage pipe networks are equipped with numerous inspection wells. Among these, the inspection wells that connect two or more upstream branches are called manifolds. Typically, most drainage pipe networks use tee manifolds as the main nodes, meaning one manifold connects one downstream pipeline and two upstream branches. Similarly, a four-way manifold connects one downstream pipeline and three upstream branches. Of course, it's understandable that the term "downstream pipeline" for a manifold is relative. In actual network layouts, besides the downstream pipeline connected to the sewage treatment plant, other so-called "downstream pipelines" are also upstream branches of a particular manifold.

[0044] Therefore, the present invention further proposes a method for dividing independent monitoring sub-regions applicable to most drainage pipe networks. Specifically, the method of dividing the network into several independent monitoring sub-regions includes:

[0045] Step S11: Retrieve non-TEVY (three-way) manifold monitoring wells within the complete monitoring area;

[0046] Step S12: Using the retrieved non-te-joint manifold detection well as the connecting manifold well, the complete monitoring area is divided into several independent monitoring sub-areas that only contain te-joint manifold wells; wherein, in the independent monitoring sub-area containing the connecting manifold well, the two upstream branches of the connecting manifold well are retained to be equivalent to the te-joint manifold well, and the remaining upstream branches of the connecting manifold well are respectively equivalent to the downstream pipelines of the corresponding other independent monitoring sub-areas;

[0047] Step S13: If no non-T-junction manifold detection well is found, the complete monitoring area is taken as an independent monitoring sub-area.

[0048] Combination Figure 2 The diagram illustrates how, using the four-way manifold H3 as the connecting manifold, two sub-regions are divided: Independent Monitoring Sub-region 1 and Independent Monitoring Sub-region 2. Each sub-region is primarily composed of three-way manifolds. H3, contained within Independent Monitoring Sub-region 2, is equivalent to a "three-way manifold." The remaining upstream branch of H3 serves as the downstream branch within Independent Monitoring Sub-region 1. The division of other complete monitoring regions can be deduced from this example and the preceding explanation; further details are omitted here. It can be further noted that if no other non-three-way manifolds are found within the entire monitoring region, it indicates that all manifolds in the pipeline network are three-way manifolds. Therefore, the resulting independent monitoring sub-unit is equivalent to the entire pipeline network region.

[0049] Based on this, for a sub-region, except for the downstream pipeline which is tested by actual measuring equipment, the method for determining the first monitoring index for other pipelines can be referred to as follows:

[0050] In some preferred embodiments, considering that factors such as siltation, drop structures, and backlogs in the drainage network may create complex flow patterns in the water body, affecting flow velocity measurements, such as the appearance of invalid data like negative or zero values, thus affecting the effective measurement of pipeline flow, the core conceptual framework proposed in the above scheme can be used to obtain the flow data of each branch line through a progressive calculation method (that is, in this example, the first monitoring indicator is flow data). Furthermore, considering that the parameters related to flow data include the concept of pollutant load, which is a composite parameter (product) of flow and water quality indicators, the second monitoring indicator in this example can be water quality data. It is understandable that water quality data covers a wider range of parameters. Many people skilled in the art can, from the perspective of the concept, requirements, and desired objectives of this invention, select stable and low-cost physicochemical indicators from the parameter indicators of water quality data in local pipelines (because the concept of this invention is to configure the actual measurement equipment of the second monitoring indicator in each branch and adopt the idea of ​​step-by-step calculation, so it can be viewed from the local perspective of the branch between two confluence wells). Such indicators include, but are not limited to, conductivity, ammonia nitrogen concentration, etc. In this way, by obtaining the actual measurement data of flow and water quality from the downstream pipeline and the actual measurement data of water quality from each upstream branch, the flow data of each upstream branch without flow measurement equipment can be obtained through step-by-step progression, thereby solving the problem of unstable flow mentioned above.

[0051] Based on this example, depending on the actual situation, such as in scenarios with relatively stable water flow, the two indicators can be swapped. That is, the first monitoring indicator can be replaced with water quality data, and the second monitoring indicator can be replaced with flow rate data. This approach can also be used to obtain the water quality calculation results for each upstream branch without deployed water quality monitoring equipment. However, those skilled in the art will understand that, in principle, swapping indicators can still achieve indicator calculations while saving significant monitoring equipment costs. However, considering the practical needs for stable and continuous monitoring, using water quality data as the first monitoring indicator is relatively less desirable than using flow rate data. Therefore, this swapping embodiment serves as a theoretically feasible reference. The specific selection of the first monitoring indicator to be calculated should be determined based on the actual pipeline network. Under more ideal pipeline network conditions, this swapping monitoring strategy can be attempted.

[0052] Therefore, the core concept of the aforementioned successive calculation method is:

[0053] Starting from the first manifold at the downstream end of the independent monitoring sub-area, the measured values ​​of the first and second monitoring indicators of the downstream pipeline of the first manifold, as well as the measured values ​​of the second monitoring indicators of the two upstream branches of the first manifold, are used to obtain the calculated values ​​of the first monitoring indicators of each upstream branch corresponding to the first manifold.

[0054] The calculated value of the first monitoring index of an upstream branch and the measured value of the second monitoring index of the same upstream branch are equivalent to the measured value of the downstream pipeline of the corresponding second manifold. The calculation results of the first monitoring index of all pipelines in the independent monitoring sub-area are obtained by performing the above calculations one by one.

[0055] Combined with the previous explanation Figure 2 As shown, for independent monitoring sub-region 2, the downstream pipeline of the first confluence well H1 at the downstream end can provide two measured values, where q1 represents the measured flow rate in the downstream pipeline of H1, and c1 represents the measured water quality in the downstream pipeline of H1; furthermore, H1 has two upstream branches, which provide measured water quality values ​​c2 and c3 respectively. Therefore, for H1, the following system of two linear equations in two variables can be constructed:

[0056] q1 = q2 + q3;

[0057] q1×c1=q2×c2+q3×c3;

[0058] Figure 2 Only the measured values ​​are shown in the figure. q2 and q3 are not shown in the figure, but it is easy to understand that they represent the flow values ​​to be calculated for the two upstream branches of H1, where q×c represents a specific parameter, the pollutant load value. The system of equations formed by the above two formulas can calculate q2 and q3. Then, for the subsequent second confluence well H2 and the third confluence well H3 (which is essentially the aforementioned connecting confluence well), the corresponding flow calculation values ​​for the two upstream branches of H2 can be obtained using the currently known q2 and the measured value c2 (q3 and c3 are calculated similarly, without further explanation). By analogy, the flow calculation values ​​for all upstream branches of this independent monitoring sub-region 2 can be obtained.

[0059] Furthermore, when two or more independent monitoring sub-regions are defined, indicating the presence of four or more access wells (the aforementioned connecting manifolds) within the complete monitoring area, it is necessary to further consider the indicator detection methods at the connecting manifolds of the multiple independent monitoring sub-regions. This invention, in conjunction with the appendix... Figure 2 Taking a four-way manifold as an example, those skilled in the art will understand that five-way manifolds or even more manifolds are rarely actually installed. Therefore, this invention will not elaborate on this. In such cases, the following concept provided by this invention can be used for implementation.

[0060] As mentioned earlier, the remaining upstream branches connecting to the manifold can be considered equivalent to the downstream pipelines of other independent monitoring sub-areas. Therefore, combined with... Figure 2The core concept of the above calculation method is that an upstream branch of H3 is equivalent to the downstream pipeline of the downstream manifold of the independent monitoring sub-region 1. Therefore, as mentioned above, the measured values ​​of two indicators of the downstream pipeline of the independent monitoring sub-region 1, namely q1' and c1', can be obtained. Then, the calculation is performed for the independent monitoring sub-region 1 in the above manner, which will not be elaborated further.

[0061] Finally, it can be added that... Figure 2 The points in the diagram are the monitoring points. For example, point 1 corresponds to q1 and c1, point 2 corresponds to q2 and c2, point 3 corresponds to q3 and c3, and point 1' corresponds to q1' and c1'. Measurement equipment is installed at these points. Typically, a manhole in the pipeline is used as the monitoring point. It's understood that there isn't just one manhole in the pipeline; there's a predetermined distance between them. Using the flow rate and water quality indicators mentioned earlier as examples, because water flow has a certain velocity, when actually deploying flow rate and water quality measurement equipment, a suitable manhole can be selected as the measurement point based on monitoring needs, manhole spacing, water flow velocity, manhole condition, and pipeline status. For example, when instantaneous monitoring data is needed, a flow meter and water quality monitoring instrument can be installed in a manhole downstream of a manifold and adjacent to that manifold. As can be understood from the above, the present invention does not limit the placement of measurement points in a close proximity manner. As long as the monitoring expectations are met and the monitoring process is stable and continuous, it is acceptable. That is, the placement of monitoring points for the aforementioned first and second monitoring indicators can be based on a preset monitoring time dimension, combined with at least one of the following factors: well spacing, well condition, pipeline and drainage status. The monitoring time dimension includes: daily average, hourly, instantaneous (a relative concept, which can be understood as real time), etc. This can be designed as needed, and the present invention does not limit it.

[0062] In summary, the main design concept of this invention lies in, compared to conventional monitoring methods, proposing to divide a pre-defined complete monitoring area of ​​the drainage network into several independent monitoring sub-areas, ensuring that each independent monitoring sub-area only contains a T-junction manhole. Then, the measured values ​​of the first monitoring index for the downstream pipeline in each independent monitoring sub-area and the measured values ​​of the second monitoring index for all pipelines in that sub-area are obtained. Next, using the measured values ​​of the first and second monitoring indexes, the calculated values ​​of the first monitoring index for all pipelines in that sub-area, excluding the downstream pipeline, are successively calculated from downstream to upstream. This invention, by using preset monitoring indicators to progressively calculate upstream pipelines, effectively avoids the influence of flow patterns. Therefore, when actually deploying the measuring equipment, it is only necessary to ensure the stability of the dual-indicator monitoring at the downstream end and the single-indicator monitoring of other branches, thus obtaining continuous and reliable monitoring index data for the entire network while significantly reducing cost.

[0063] Corresponding to the above embodiments and preferred solutions, the present invention also provides an embodiment of a drainage pipe network index detection device 300, such as... Figure 3 As shown, it may specifically include the following components:

[0066] The monitoring index calculation module 303 is used to calculate the first monitoring index value of all pipelines in the sub-region except the downstream pipeline by using the measured value of the first monitoring index and the measured value of the second monitoring index in the direction from downstream to upstream.

[0070] The second sub-region setting unit is used to treat the entire monitoring area as an independent monitoring sub-region if no non-T-junction flow-type detection well is found.

[0071] Furthermore, the monitoring indicator calculation module includes:

[0072] The initial calculation unit is used to start from the first manifold at the downstream end of the independent monitoring sub-area, and use the measured values ​​of the first and second monitoring indicators of the downstream pipeline of the first manifold, as well as the measured values ​​of the second monitoring indicators of the two upstream branches of the first manifold, to calculate the first monitoring indicator values ​​corresponding to each upstream branch of the first manifold.

[0073] The progressive calculation unit is used to calculate the first monitoring index of all pipelines in the independent monitoring sub-area by taking the calculated value of the first monitoring index of an upstream branch and the measured value of the second monitoring index of the same upstream branch as the measured value of the downstream pipeline of the corresponding second manifold.
