Description

Technical Field

[0001] The present application relates to the field of monitoring and early warning, and in particular, to a method, device, electronic device and medium for early warning analysis of drainage pipeline network collapse. Background Art

[0002] Urban drainage pipeline network is the backbone project for urban water pollution prevention and control and urban waterlogging prevention and drainage. It is responsible for collecting urban domestic sewage and industrial production wastewater and timely discharging urban rainwater runoff, and is an important lifeline to ensure the normal operation of the city.

[0003] With the acceleration of the urbanization process, the number of underground drainage pipelines has increased rapidly. At present, the management of municipal drainage pipeline network facilities has a low scientific and technological content, backward technical equipment, low automation level, and mostly manual operation, resulting in low management efficiency. As a result, internal hidden dangers in the pipeline network cannot be detected in time during daily management, and effective measures cannot be taken in time to intervene in the face of sudden problems, which in turn leads to a series of problems such as road collapse, groundwater pollution, urban waterlogging, and low influent concentration of sewage treatment plants. How to improve the management level of the drainage pipeline network, change from extensive management to refined management, and change from ex post emergency to ex ante early warning is the future direction of drainage pipeline network management.

[0005] A method for early warning analysis of drainage pipeline network collapse provided by an embodiment of the present application includes the following steps:

[0006] Obtain the liquid level elevation information of each inspection well in the drainage pipeline network of the target area; the drainage pipeline network includes at least one pipeline, each pipeline includes a plurality of pipe segments, and the pipe segments are located between two inspection wells;

[0009] When there is a blocked pipe segment in the target pipeline, determine the information of the blocked pipe segment.

[0010] In some embodiments, in the method for early warning analysis of drainage pipe network collapse, according to the pre-configured topological relationship model and liquid level elevation information of the drainage pipe network in the target area, the liquid level change result from top to bottom of the target pipeline is determined, including:

[0049] It should be noted that the term "including" will be used in the embodiments of the present application to indicate the existence of the subsequently stated features, but does not exclude the addition of other features.

[0050] Urban drainage pipe networks are the backbone projects for urban water pollution prevention and control and urban waterlogging prevention and drainage. They are responsible for collecting urban domestic sewage and industrial production wastewater and promptly discharging urban rainwater runoff. They are an important lifeline to ensure the normal operation of the city.

[0051] With the acceleration of the urbanization process, the number of underground drainage pipelines has increased rapidly. At present, the management of municipal drainage pipe network facilities has a low scientific and technological content, backward technical equipment, low automation level, and mostly manual operations, resulting in low management efficiency. As a result, hidden dangers inside the pipe network cannot be discovered in a timely manner during daily management, and effective measures cannot be taken in a timely manner to intervene in the face of sudden problems, thus triggering a series of problems such as road collapses, groundwater pollution, urban waterlogging, and low influent concentration of sewage treatment plants. If the management level of drainage pipe networks can be improved, changing from extensive management to refined management and from post-emergency response to pre-warning, it will be the future direction of drainage pipe network management.

[0052] Existing sewage pipe network monitoring systems are generally one-enterprise-one-pipe monitoring systems, that is: an on-line monitoring room is set at the total discharge port of each enterprise to separately monitor the water quality and quantity of the drainage of each enterprise. According to the indicators of the wastewater discharged by each enterprise, by controlling the opening and closing of the valves of each enterprise, it is avoided that the drainage indicators of some enterprises in the industrial park do not meet the standards and affect the water environment safety. However, the state of a certain pipe section cannot be monitored and predicted.

[0053] In addition, although the fixed-point monitoring and manual inspections of existing external pump houses of enterprises can achieve the monitoring of sewage manholes in a certain range, manual inspections have limitations and cannot timely and comprehensively detect the collapse of pipe sections. First of all, since the sewage pipe network is underground and not easy to observe, it is difficult for manual inspections to timely detect the collapse phenomenon. Often, after a certain section of sewage is blocked and overflows, or even reported to the relevant departments by citizens, the collapse phenomenon of the sewage pipe network will be discovered; secondly, manual supervision of collapses is time-consuming, laborious, costly, and the results are not good.

[0054] Based on this, the drainage network collapse warning analysis method described in the embodiments of the present application obtains dynamic monitoring data of the liquid level of the urban sewage network by deploying equipment, combines the geophysical exploration basic data of the drainage network in the target area (the connection relationship before and after the well position and the overall flow direction of the water body, the confluence situation of the branch pipes), processes the dynamic monitoring data to timely detect the blocked and collapsed pipe sections, thereby realizing the collapse warning function with low labor cost.

[0055] Please refer to Figure 1 , Figure 1 which shows the drainage network collapse warning analysis method described in the embodiments of the present application. Specifically, the method includes the following steps S101 - S104;

[0056] S101. Obtain the liquid level elevation information of each inspection well in the drainage network of the target area; the drainage network includes at least one pipeline, each pipeline includes multiple pipe sections, and the pipe sections are located between two inspection wells;

[0057] S102. According to the pre - configured topological relationship model and liquid level elevation information of the drainage network in the target area, determine the liquid level change result from top to bottom of the target pipeline; the liquid level change result includes the liquid level index of each pipe section in the target pipeline;

[0058] S103. According to the liquid level change result, judge whether each pipe section in the target pipeline meets the preset liquid level change condition, and judge whether there is a blocked pipe section in the target pipeline; among them, the preset liquid level change condition corresponding to the target pipeline is different due to the different topological relationships of the target pipeline in the topological relationship model;

[0059] S104. When there is a blocked pipe section in the target pipeline, determine the information of the blocked pipe section.

[0060] For the drainage network collapse warning analysis method described in the embodiments of the present application, after obtaining the liquid level elevation information of each inspection well in the drainage network of the target area, according to the pre - configured topological relationship model and liquid level elevation information of the drainage network in the target area, determine the liquid level change result from top to bottom of the target pipeline, and then according to the liquid level change result, judge whether each pipe section in the target pipeline meets the preset liquid level change condition, and judge whether there is a blocked pipe section in the target pipeline, so as to be able to detect the collapse / blockage problem early and give a warning, reminding the operation and maintenance personnel to intervene early to avoid road collapse or sewage overflow.

[0061] In an embodiment of the present application, the drainage pipe network collapse early warning analysis method can run on a terminal device or a server; among them, the terminal device can be a local terminal device. When the drainage pipe network collapse early warning analysis method runs on the server, the drainage pipe network collapse early warning analysis method can be implemented and executed based on a cloud interaction system, where the cloud interaction system at least includes a server and a client device (i.e., the terminal device).

[0062] Specifically, taking the application to the server as an example, the drainage pipe network collapse early warning analysis method will be specifically described.

[0063] Before obtaining the liquid level elevation information of each inspection well in the drainage pipe network in step S101, the liquid level elevation information of each inspection well is collected through a monitoring system deployed in the drainage pipe network.

[0064] The monitoring system includes a liquid level elevation acquisition device and a communication device provided in each inspection well. The liquid level elevation acquisition device collects the liquid level elevation information in the inspection well and sends the collected liquid level elevation information to the server through the communication device, so that the server obtains the liquid level elevation information of each inspection well in the drainage pipe network of the target area.

[0065] Specifically, when the monitoring system meets the preset acquisition conditions, it collects the liquid level elevation information of each inspection well and sends the liquid level elevation information of each inspection well to the server. The preset acquisition conditions at least include: collecting according to a preset acquisition frequency.

[0066] That is to say, the server receives the real-time and dynamic monitoring data of the drainage pipe network in the target area, and processes the monitoring data in real time to timely discover whether the pipe segments of the underground drainage pipe network collapse or are blocked.

[0067] In step S101, the drainage pipe network usually includes multiple pipelines, and the pipe segments include a main pipeline and branch pipelines that converge into the main pipeline.

[0068] In the liquid level elevation information of each inspection well, it includes the liquid level height of the inspection well and the identifier of the inspection well, such as the number information of the inspection well, so that in step S102, when determining the liquid level change result from top to bottom of the target pipeline according to the pre-configured topological relationship model of the drainage pipe network in the target area and the liquid level elevation information, according to the inspection well identifier in the liquid level elevation information, the liquid level elevation corresponds to the inspection well in the topological relationship model.

[0069] In step S102, according to the pre-configured topological relationship model and liquid level elevation information of the drainage pipe network in the target area, determine the liquid level change result of the target pipeline from top to bottom; wherein, the topological relationship model of the drainage pipe network in the target area includes inspection wells, pipe segments, and sewage flow directions. Please refer to Figure 2 , in the figure, the circles identify the inspection wells, the arrows represent the pipe segments between two inspection wells, and the arrow direction represents the sewage flow direction in the pipe segment.

[0070] For the drainage pipe network in the target area of the city, it often needs to flow from upstream to downstream until it reaches the sewage treatment plant or drainage outlet. Therefore, the bottom elevation of each pipe segment in the drainage pipe network is different and gradually decreases from upstream to downstream; at the same time, the liquid level elevation of each pipe segment in the drainage pipe network also gradually decreases. When a pumping station or a branch line is incorporated into a certain pipe segment, the liquid level elevation of the inspection well of this pipe segment may be higher than that of the previous inspection well.

[0071] Based on basic information such as the pipe network topological relationship and the liquid level elevation of the inspection wells, analyze the online monitoring data, calculate using the topological relationship model of the drainage pipe network, and perform gradient analysis on the associated pipelines. The model will first judge the upstream and downstream topological relationship of the pipeline. Exemplarily, please refer to Figure 2 , inspection wells W1, W2, W3, W4, W5, W6, W7, W8, and W9 are located on the main pipeline and are in a connection relationship. The bottom elevation of the pipeline from inspection well W1 to inspection well W9 shows a certain descending gradient; since there are no branch lines incorporated into the pipe segments of inspection wells W1, W2, W3, W4, and W5, under normal circumstances, the liquid levels of inspection wells W1, W2, W3, W4, and W5 should also show a similar descending gradient. If the liquid level gradient change between two inspection wells is abnormal, it can be judged that there is a problem with the pipeline between the two inspection wells, suspected of being blocked, collapsed, etc. The model judges that inspection wells E001, E002, and E003 are in a connection relationship, and there is a branch line incorporated at inspection well E002. The gradient analysis of the three should consider the gradient change caused by the incorporated branch line, and on this basis, perform liquid level gradient analysis.

[0072] Specifically, please refer to Figure 3 , Figure 3 shows a schematic diagram of the change law of the liquid level elevation described in the embodiment of the present application.

[0073] Based on this, please refer to Figure 4 , the determination of the liquid level change result of the target pipeline from top to bottom according to the pre-configured topological relationship model and liquid level elevation information of the drainage pipe network in the target area described in the embodiment of the present application includes:

[0074] S401. Determine the inlet inspection well and the outlet inspection well of each pipe section in the target pipeline according to the pre-configured topological relationship model of the drainage pipe network in the target area.

[0075] S402. Calculate the liquid level index of the pipe section according to the liquid level elevation information of the inspection well at the inlet of each pipe section and the liquid level elevation information of the inspection well at the outlet.

[0076] S403. Determine the liquid level gradient change result of the target pipeline from upstream to downstream according to the liquid level index of each pipe section.

[0077] Specifically, the liquid level index of the pipe section includes the liquid level elevation of the pipe section and the liquid level difference index between the inspection well at the inlet and the inspection well at the outlet.

[0078] The liquid level elevation of the pipe section is at least one of the following: the liquid level elevation of the inspection well at the inlet, the liquid level elevation of the inspection well at the outlet, and the average value of the liquid level elevations of the inspection wells at the inlet and the outlet.

[0079] The liquid level difference index is at least one of the following: the difference between the liquid level elevations of the inspection wells at the inlet and the outlet, or the liquid level gradient calculated based on the liquid level elevations of the inspection wells at the inlet and the outlet.

[0080] That is to say, in the embodiment of the present application, the liquid level elevation acquisition device is installed in the inspection well, and then the liquid level index of the pipe section is calculated by using the liquid level elevation of the inspection well.

[0081] Specifically, in the embodiment of the present application, the liquid level elevation acquisition device is installed on the manhole cover of the inspection well.

[0082] If the liquid level elevation acquisition device is directly installed in the pipe section to directly collect the liquid level elevation of the pipe section, there are the following technical obstacles: firstly, it is very difficult to install the liquid level elevation acquisition device and it is even more difficult to repair; secondly, the environment in the pipe section is poor, and the liquid level rises sharply when it rains, and the liquid level elevation acquisition device is very easy to break.

[0083] Therefore, in the embodiment of the present application, the liquid level index of the pipe section is calculated by using the liquid level elevation of the inspection well.

[0084] Specifically, only the liquid level elevation of the inspection well at the inlet and the liquid level elevation of the inspection well at the outlet can be used as the liquid level elevation in the pipe section, or the average value of the liquid level elevations of the inspection wells at the inlet and the outlet. Because the drainage pipe network collapse warning analysis method described in the embodiment of the present application focuses on the liquid level change result from top to bottom of the target pipeline, as long as the liquid level elevation calculation standard in the pipe section is unified, a good warning effect can be obtained.

[0085] Since the pipe section has a certain slope, the liquid level difference at both ends of the pipe section should also have a certain difference. When the pipe section is blocked or collapsed, the sewage cannot flow or the flow rate is reduced, and the liquid level difference at both ends of the pipe section will decrease or even disappear. Therefore, the liquid level difference index is calculated.

[0086] Exemplarily, the liquid level gradient calculated based on the liquid level elevations of the inlet inspection well and the outlet inspection well may be: the ratio of the difference between the liquid level elevations of the inlet inspection well and the outlet inspection well to the length of the pipe section.

[0087] In the embodiment of the present application, before judging whether each pipe section in the target pipeline meets the preset liquid level change condition according to the liquid level change result and judging whether there is a blocked pipe section in the target pipeline, the method further includes:

[0088] Determine whether there is a pipeline confluence and / or pump station confluence confluence pipe section in the target pipeline according to the topological relationship model, and determine the topological relationship of the target pipeline;

[0089] According to the topological relationship of the target pipeline, a preset liquid level change condition corresponding to each pipe section in the target pipeline is determined.

[0090] In the embodiment of the present application, specifically, when the target pipeline does not have an incoming pipe section where the pipeline merges and / or the pump station merges, the preset liquid level change condition corresponding to the target pipeline is: in the pipe sections from top to bottom of the target pipeline, the liquid level elevation becomes lower and lower, and the liquid level difference index of each pipe section satisfies the preset liquid level difference range;

[0091] When the target pipeline has an incoming pipe section where the pipeline merges and / or the pump station merges, the preset liquid level change condition corresponding to the target pipeline is: the target pipeline is divided into multiple pipe section groups based on the incoming pipe section, and the liquid level elevations in the pipe sections from top to bottom of the pipe section group become lower and lower, and the liquid level difference index of each pipe section satisfies the preset liquid level difference range; the liquid level elevation of the incoming pipe section is not greater than the preset incoming elevation threshold.

[0092] The characteristics of pipe section collapse warning are: under normal circumstances, the water level elevations of several adjacent wells change from high to low. In the absence of a sewage lift pump, the liquid level elevation generally does not show too large a difference. After the pipe section collapses, due to the blockage of the pipe section, the pipe section presents a situation where the upstream pipe is full of water and there is no water flow downstream. The difference in liquid level elevations between the upstream and downstream pipe sections will be large. As the upstream pipe is full of water, the liquid level difference index in the upstream pipe section decreases, while the liquid level elevation of the upstream pipe section suddenly soars; the liquid level elevation of the downstream pipe section drops precipitously, and the liquid level difference index in the downstream pipe section decreases.

[0093] Based on this, in the embodiment of the present application, in the drainage network collapse early warning analysis method, please refer to Figure 5, based on the liquid level change result, determine whether each pipe section in the target pipeline meets the preset liquid level change condition, and determine whether there is a blocked pipe section in the target pipeline, including the following S501 - S502;

[0094] S501. According to the liquid level indicators of three adjacent pipe sections, determine whether the lower pipe section and the upper pipe section among the three adjacent pipe sections meet the preset abnormal conditions;

[0095] S502. If satisfied, determine the middle pipe section among the three adjacent pipe sections as the blocked pipe section;

[0096] Determine whether the lower pipe section and the upper pipe section among the three adjacent pipe sections meet the preset abnormal conditions, including at least one of the following:

[0097] Determine whether the liquid level elevation of the lower pipe section is lower than the preset lowest liquid level threshold corresponding to this pipe section, and whether the liquid level elevation of the upper pipe section is higher than the preset highest liquid level threshold corresponding to this pipe section;

[0098] Determine whether the difference in liquid level elevation between the upper pipe section and the lower pipe section is greater than the preset highest liquid level difference threshold corresponding to this pipe section;

[0099] Determine whether the liquid level difference index of the lower pipe section is lower than the preset lowest liquid level difference threshold corresponding to this pipe section, and whether the liquid level difference index of the upper pipe section is lower than the preset lowest liquid level difference threshold corresponding to this pipe section.

[0100] Exemplarily, take the upper pipe section W1 - W2 between inspection wells W1 and W2; the middle pipe section W2 - W3 between inspection wells W2 and W3, and the lower pipe section W3 - W4 between inspection wells W3 and W4; when it is judged that the upper pipe section W1 - W2 is higher than the preset highest liquid level threshold corresponding to this pipe section, and the lower pipe section W3 - W4 is lower than the preset lowest liquid level threshold corresponding to this pipe section, it indicates that the middle pipe section W2 - W3 is blocked or collapsed, resulting in unfavorable drainage of the upper pipe section W1 - W2, and the inflow volume has not decreased, thus causing sewage accumulation and a super-high liquid level elevation; at the same time, it causes a decrease in the inflow of the pipe section W3 - W4, while the drainage volume remains unchanged, thus causing sewage accumulation and an ultra-low liquid level elevation.

[0101] Exemplarily, when it is judged here that the difference in liquid level elevation between the upper pipe section W1 - W2 and the lower pipe section W3 - W4 is greater than the preset highest liquid level difference threshold corresponding to this pipe section, it also indicates that the drainage of the upper pipe section W1 - W2 is unfavorable, and the inflow of the lower pipe section decreases, thus indicating that the middle pipe section W2 - W3 is blocked or collapsed.

[0102] Among them, the preset lowest liquid level threshold, preset highest liquid level threshold, preset lowest liquid level difference threshold, and preset highest liquid level difference threshold corresponding to each pipe section are determined according to partial historical liquid level indicators of this pipe section.

[0103] Specifically, based on the partial historical liquid level elevation of the pipe section, determine the corresponding preset minimum liquid level threshold and preset maximum liquid level threshold for this pipe section.

[0104] Based on the partial historical liquid level elevation of the upstream pipe section and the partial historical liquid level elevation of the downstream pipe section, determine the corresponding preset maximum liquid level difference threshold for this pipe section.

[0105] Based on the partial historical liquid level difference index of the pipe section, determine the corresponding preset minimum liquid level threshold for this pipe section.

[0106] Since the preset minimum liquid level threshold, preset maximum liquid level threshold, preset minimum liquid level difference threshold, and preset maximum liquid level difference threshold corresponding to each pipe section are determined according to the partial historical liquid level index of this pipe section, therefore, the preset minimum liquid level threshold, preset maximum liquid level threshold, preset minimum liquid level difference threshold, and preset maximum liquid level difference threshold corresponding to each pipe section are all different; even in the case of branch pipes merging in, such as E001, E002, E002, it is also possible to accurately judge whether the middle pipe section among three adjacent pipe sections is a blocked pipe section.

[0107] Here, it should be noted that to determine whether the lower pipe section and the upper pipe section among three adjacent pipe sections meet the preset abnormal conditions in the embodiments of the present application, only one preset abnormal condition needs to be met to judge that the middle pipe section is a blocked pipe section, thereby improving the sensitivity of early warning.

[0108] In the embodiments of the present application, when any pipe section is blocked or collapses, it will affect the liquid level elevation difference between its upper pipe section and lower pipe section, and affect the liquid level difference index in the upper pipe section and lower pipe section. The embodiments of the present application utilize these more detailed change results to more sensitively judge the blocked pipe section in the pipeline, rather than simply determining whether there is a blockage based on the liquid level elevation in the inspection well, and can detect the blocked pipe section in the pipeline earlier and give an early warning.

[0109] In step S104 of the embodiments of the present application, when there is a blocked pipe section in the target pipeline, determine the information of the blocked pipe section, and the information of the blocked pipe section includes information such as the number, location, and attribute parameters of the blocked pipe section.

[0110] After determining the information of the blocked pipe section, send the information of the blocked pipe section to the early warning terminal, so that the early warning terminal gives an early warning prompt according to the preset prompt method, thereby detecting the collapse / blockage problem earlier and giving an early warning, reminding the operation and maintenance personnel to intervene earlier to avoid causing road collapse or sewage overflow.

[0111] In an embodiment of the present application, the method for early warning analysis of drainage pipe network collapse further includes: after determining the liquid level change result from top to bottom of the target pipeline according to the topological relationship model and liquid level elevation information of the drainage pipe network in the target area configured in advance, generating a sectional analysis diagram of the pipe section along the line based on the liquid level change result, and sending the sectional analysis diagram of the pipe section along the line to a terminal device to display the sectional analysis diagram of the pipe section along the line on the screen of the terminal device.

[0112] Please refer to Figure 6 , Figure 6 which shows a sectional analysis diagram of the pipe section along the line of the target pipeline composed of manholes WS16, WS24, WS32, and WS44.

[0113] It should be noted that manholes WS16, WS24, WS32, and WS44 are not in the Figure 2 shown topological relationship model and are only used for illustration.
