Fig. 3 shows a real-time conductivity schematic diagram of a regional linkage management method for an urban drainage network according to an embodiment of the application.
In one implementation scenario, the real-time conductivity schematic shown in fig. 3 is obtained by monitoring the drainage pipe network, where the ordinate is the conductivity unit, and the unit is: ms/cm, the abscissa is the time unit, the concrete unit is: and (3) days. As can be seen from fig. 3, if the conductivity mutation is detected at the node of the east branch pipe, the main pipe obtains the conductivity change condition of the west branch pipe which is synchronous with the east branch pipe and is positioned at the upstream of the east branch pipe, if the conductivity of the west branch pipe is normal, the conductivity of the main pipe suddenly changes, the conductivity peak trend of the main pipe is consistent with the conductivity peak trend of the east Lu Zhiguan, and the conductivity peak of the main pipe is lower than the conductivity peak of the east branch pipe, the problem of water pollution of the east branch pipe can be considered. By the method, the search range of the pollution discharge source can be greatly and accurately reduced, most of investigation workload is reduced, a water quantity and conductivity comprehensive index distributed monitoring network covering the whole process can be established aiming at important monitoring areas such as an industrial park, a pollution discharge event is sharply identified, and a discharge track is accurately identified.
In an embodiment, the method further comprises: firstly, acquiring the real-time conductivity and the real-time flow of a drainage node; then, determining a conductivity variation coefficient based on the real-time conductivity and the historical conductivity; then, determining the real-time water outlet conductivity based on the real-time conductivity and the real-time flow; and then, determining the conductivity stability index of the corresponding drainage node according to the conductivity variation coefficient and the real-time effluent conductivity.
Furthermore, according to the embodiment of the application, whether the corresponding drainage node has the rainy day mixed flow characteristic can be determined through the conductivity and the flow, and quantitative analysis is performed on the drainage node with the rainy day mixed flow characteristic. Based on the fact that the time of the drainage pipe network and actual weather does not completely correspond, for example, in the third day after rain, part of the drainage pipe network still has rainy day mixed flow characteristics, and the rainy day mixed flow characteristics can influence specific numerical values of various set reference values, for example, water quality detection values in dry days and waterlogging days are different, the corresponding various set reference values are determined through the rainy day mixed flow characteristics, and the determination of various set reference values can be more accurate instead of being determined directly through weather.
Specifically, the present application requires determining the conductivity stability of the drain node prior to determining whether the drain node currently has a rainy day mixed flow characteristic. The method comprises the steps of determining a conductivity variation coefficient and a water outlet conductivity by analyzing the real-time conductivity and the real-time flow of a drainage node, and determining a conductivity stability index of the drainage node when the conductivity variation coefficient does not exceed a target coefficient threshold and the real-time water outlet conductivity accords with a target water outlet conductivity range.
In another implementation scenario, the following approach may be employed: the inlet water concentration is lower in rainy days of a sewage plant at the downstream of a certain city, the inlet water quantity is increased rapidly, the inlet water quantity is quantitatively analyzed in rainy days of the sewage plant, engineering measures of diversion modification of a pipe network are guided, the aim of cleaning and diversion of the pipe network is achieved, and the sewage pipe network is monitored on line for 24 hours in flow-conductivity. And a plurality of monitoring points are distributed together to cover the main pipe nodes of the sewage pipe network, the municipal connection points of the communities and the urban water system, the conductivity variation coefficients among the detection points are determined by comparing the point conductivities of the monitoring points, and if the conductivity variation coefficients do not exceed a target coefficient threshold value and the real-time water outlet conductivities all meet the target water outlet conductivity range, the stability index corresponding to the conductivity stability of the water outlet nodes is determined.
Further, under the weather without precipitation, the conductivity data of the monitoring points are compared day by day to determine the continuity of the conductivity, and the liquid level and the flow data of the monitoring points are compared day by day to determine the continuity of the liquid level and the flow data. For example, the conductivity continuous float range is 10%, the liquid level continuous float range is 10%, and the continuous float range of the flow rate data is 10%. And determining a stability index corresponding to the conductivity based on the continuity and the stability. For example, in the implementation scenario, the stability index of the drainage node corresponding to the plurality of monitoring points is: the conductivity variation coefficient is smaller than 10%, the conductivity continuous floating range is 10%, the liquid level continuous floating range is 10%, the continuous floating range of flow data is 10%, and the conductivity of the community effluent is 1642 mu s/cm.
In an embodiment, the method further comprises: firstly, acquiring the real-time liquid level of a drainage node; then, under the condition that the real-time flow and the real-time liquid level are in an ascending trend and the real-time conductivity is in a descending trend, determining that the drainage node currently has a rainy day mixed flow characteristic; then, determining the real-time unit area infiltration amount of the drainage node based on the corresponding real-time flow and real-time liquid level; then, quantitatively analyzing the infiltration quantity and the precipitation quantity in real time in unit area, and determining the relation value of theoretical precipitation and infiltration and the corresponding fitting degree; and then, if the fitting degree meets the target fitting degree, determining the relation value of the theoretical precipitation and the infiltration as the relation value of the actual precipitation and the infiltration.
Specifically, based on the floating ranges of various stability indexes, the maximum predicted value and the minimum predicted value of the indexes, namely the corresponding conductivity range, flow range and liquid level range, can be determined, when the real-time flow is larger than the flow range by a specified proportion, for example, 10% beyond the flow range, the real-time flow can be determined to have an ascending trend, otherwise, when the real-time flow is smaller than the flow range by a specified proportion, for example, 10% beyond the flow range, the real-time flow can be determined to have a descending trend. The same is true for the liquid level range and the conductivity range, which are not illustrated below, wherein the specified ratios are not limiting and different types of specified ratios may be different.
When the real-time flow and the real-time liquid level are in an ascending trend and the real-time conductivity is in a descending trend, the fact that the corresponding drainage node has a rainy day mixed flow characteristic can be determined. And then calculating according to the real-time flow and the real-time liquid level according to a conventional method, determining the real-time unit area infiltration amount of the drainage node, drawing a chart to perform straight line fitting on the real-time unit area infiltration amount and the real-time precipitation amount by taking the real-time unit area infiltration amount as an ordinate and the real-time precipitation amount as an abscissa, and determining a theoretical precipitation-infiltration relation value corresponding to a fitting result as an actual precipitation-infiltration relation value if the fitting degree meets a target fitting degree.
For example: from the plotted graph, the equation y=155.52x+176.27, r can be found 2 =0.76. Wherein R is 2 The method is used for representing the fitting degree, the fitting degree meets the target fitting degree, namely, the real-time unit area infiltration amount and the real-time precipitation amount have higher correlation, at the moment, the theoretical precipitation and infiltration relation value corresponding to the equation can be determined as the actual precipitation and infiltration relation value, namely, each time 10mm rainfall is increased, the unit area infiltration amount is increased by 1555m 3 。
In an embodiment, the method further comprises: dividing sources of drainage households according to drainage information of the drainage households, and determining primary drainage nodes; partitioning the discharge source based on the flow direction information of the primary drainage nodes to determine the secondary drainage nodes; determining a third-level drainage node based on the connection information of the second-level drainage node and the main pipeline; determining corresponding pump station information and sewage treatment plants based on the flow direction information of the three-stage drainage nodes; and determining a drainage pipe network map based on the primary drainage node, the secondary drainage node, the tertiary drainage node, the pump station information and the sewage treatment plant. By the method, the drainage pipe network map can be obtained, and the various schemes are applied based on the drainage pipe network map.
