Description

Technical Field

[0001] The present application relates to the technical field of urban drainage systems, and in particular to a method, device, electronic equipment and storage medium for detecting water level in a drainage network. Background Art

[0002] In the urban underground drainage network, the water level needs to be monitored. By real-time monitoring of the water level changes in the drainage network, early warning of urban waterlogging and flooding can be provided to reduce disaster losses. At the same time, monitoring the water level can help understand the working status and performance of the pipeline, thereby optimizing the operation of the network and the design of the drainage system and improving drainage efficiency.

[0003] In the related technology, the water level gauges commonly used in urban underground drainage pipe networks include pressure level gauges, ultrasonic level gauges, and radar level gauges.

[0004] However, pressure level gauges need to be in direct contact with liquids and are easily clogged by impurities such as sludge, which affects the measurement accuracy and service life of the equipment. In addition, in domestic urban underground drainage networks, some pipes do not separate rainwater and sewage, making pressure level gauges more susceptible to contamination and requiring more frequent maintenance and cleaning, increasing operation and maintenance costs.

[0005] There are certain blind spots when ultrasonic level meters are measuring. That is, when ultrasonic waves are emitted, they are excited by high-voltage pulses. After the pulse ends, there will be a certain period of attenuation oscillation. During this period, the tail signal and the echo signal are generally indistinguishable. Therefore, ultrasonic level meters usually set a delay for a period of time after the emission pulse excitation before entering the receiving state. The delay shields the close-range echo signal, but brings a close-range measurement blind spot to the ultrasonic level meter. In addition, the measurement signal of the ultrasonic level meter may be interfered by environmental factors such as steam, foam, and dust in the drainage pipeline, resulting in increased measurement errors.

[0006] Radar level gauges have certain monitoring blind spots, and both ultrasonic level gauges and radar level gauges can only measure water below the level gauge. Therefore, when the city is flooded and the water level overflows the level gauge, measurement cannot be performed.

[0007] In summary, in the related technology, due to the influence of the design structure of the liquid level meter itself, it is difficult to accurately obtain the water level data of the urban drainage network, which affects the urban drainage efficiency and needs to be improved.

[0029] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The following describes the water level detection method, device, electronic device and storage medium of the drainage network of the embodiment of the present application with reference to the accompanying drawings. In view of the technical problem that in the related art mentioned in the above background technology, it is difficult to accurately obtain the water level data of the urban drainage network due to the influence of the design structure of the liquid level meter itself, thereby affecting the urban drainage efficiency, the present application provides a multimedia sharing method of an electronic device, in which the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters can be calculated based on the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters, so that at least one preset detection point that meets the preset detection conditions is selected from multiple preset detection points according to the theoretical water level, so as to obtain the actual water level of the drainage network based on the water level data of at least one preset detection point, reduce the influence of the characteristics of the liquid level meter itself on the water level detection result, obtain more accurate water level data of the urban drainage network, and help improve the urban drainage efficiency. Thus, the technical problem that in the related art, it is difficult to accurately obtain the water level data of the urban drainage network due to the influence of the design structure of the liquid level meter itself, thereby affecting the urban drainage efficiency is solved.

[0031] Specifically, Figure 1 A schematic flow chart of a method for detecting water level in a drainage network provided in an embodiment of the present application.

[0032] like Figure 1 As shown, the water level detection method of the drainage network includes the following steps:

[0033] In step S101, water level data of a plurality of preset detection points in a drainage network of a target city are obtained.

[0034] It is understandable that the commonly used water level gauges in urban underground drainage networks include pressure level gauges, ultrasonic level gauges, and radar level gauges. Among them, the pressure level gauge needs to be in direct contact with the liquid and is easily blocked by impurities such as sludge, which affects the measurement accuracy and the service life of the equipment. In addition, in the domestic urban underground drainage network, some pipes have not achieved rain and sewage separation, making the pressure level gauge more susceptible to pollution and requiring more frequent maintenance and cleaning, which increases the operation and maintenance costs. There are certain blind spots when the ultrasonic level meter is measured, that is, when the ultrasonic wave is emitted, it is excited by a high-voltage pulse. After the pulse ends, there will be a certain length of attenuation oscillation. During this period of time, the tail signal and the echo signal are generally indistinguishable. Therefore, the ultrasonic level meter usually sets a delay for a period of time after the emission pulse excitation, and then enters the receiving state. The delay shields the close-range echo signal, but brings a close-range measurement blind spot to the ultrasonic level meter. In addition, the measurement signal of the ultrasonic level meter may be interfered by environmental factors such as steam, foam, and dust in the drainage pipeline, resulting in increased measurement errors. Radar level gauges have certain monitoring blind spots, and both ultrasonic level gauges and radar level gauges can only measure water below the level gauge. Therefore, when the city is flooded and the water level overflows the level gauge, measurement cannot be performed.

[0035] Therefore, the embodiment of the present application can set up multiple detection points, and set up an ultrasonic level meter or a radar level meter at each detection point to detect the water level data below the detection point.

[0036] The positions of the detection points can be set accordingly by those skilled in the art according to the actual structure of the urban drainage network, and the heights of all the detection points are different.

[0037] In step S102, the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters are obtained, and the theoretical water level of the drainage network is calculated based on the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters.

[0038] During the actual implementation process, the embodiments of the present application can also obtain the current environmental data of the target city, such as the current rainfall, current temperature, current humidity, etc., obtain the design parameters of the drainage network, such as pipe size, slope, drainage allowable speed range, etc., and obtain the current drainage operation parameters of the drainage network, such as the number of water pump starts, water temperature, water flow rate, etc.

[0039] According to the current environmental data, the design parameters of the drainage network and the current drainage operation parameters, the embodiment of the present application can estimate the theoretical water level of the drainage network.

[0040] Optionally, in one embodiment of the present application, the theoretical water level of the drainage network is calculated based on the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters, including: obtaining the current climate conditions and current rainfall of the target city and the current construction status of each water inlet of the drainage network that meets the preset influencing conditions based on the current environmental data; obtaining the operating status of each drainage pump of the drainage network based on the current drainage operation parameters; estimating the wear coefficient of the drainage network based on the usage time and historical water level data of the drainage network; matching the corresponding urban water use time period based on the current detection time, and matching the corresponding urban water use in a preset urban water use database with the urban water use time period as an index; substituting the current climate conditions, current rainfall, current construction status, operation status, wear coefficient and urban water use into a pre-constructed theoretical water level calculation formula to obtain the theoretical water level.

[0041] It is understandable that there are many factors that affect the water level of the drainage network, such as whether it is currently raining, whether there are drainage difficulties caused by construction or the presence of a large amount of sedimentable substances in the sewage, whether there are sections of road with serious waterlogging, whether each drainage pump can operate normally, the wear and tear of the drainage network, whether it is currently the peak period of urban water use, etc.

[0042] Therefore, the embodiments of the present application can obtain the current climate conditions from the current environmental data, such as whether the city is currently in the rainy season, whether the city is currently in the high temperature season / low temperature season (such as high temperature will cause the city's water use to increase, low temperature will cause sewage to freeze, etc.), and obtain the current rainfall; and whether there is a construction area that affects drainage near each inlet and outlet of the city's drainage network, where the preset influencing conditions may include whether the distance between the construction area and the inlet and outlet is less than a certain threshold, the construction type (such as whether there is a probability of sediment falling into the drainage pipe), etc., which can be specifically set by technical personnel in this field according to actual conditions, and no specific restrictions are made here.

[0043] The embodiment of the present application can also obtain the operating status of each drainage pump in the drainage network from the current drainage operating parameters, so as to determine the drainage capacity of the drainage network according to the operating status of the drainage pump.

[0044] The embodiment of the present application can also estimate the wear coefficient of the drainage network based on the usage time and historical water level data of the drainage network.

[0045] The embodiment of the present application can also determine the urban water use time period to which the current detection moment belongs, such as the peak water use period, and use the urban water use time period as an index to match the corresponding urban water consumption in a preset urban water use database, wherein the preset urban water use database can be set in the cloud and store regularly uploaded water use data and water use time periods.

[0046] Furthermore, the embodiments of the present application can quantify the acquired data that may affect the water level of the drainage network, and substitute the quantified current climate conditions, current rainfall, current construction status, operating status, wear coefficient and urban water consumption into a pre-constructed theoretical water level calculation formula to obtain the theoretical water level.

[0047] For example, the theoretical water level calculation formula can be constructed and trained by historical water level data, or the product of the quantized value and the wear coefficient can be used as a reference value and searched in a preset theoretical water level-reference value comparison table. The theoretical water level-reference value comparison table can be constructed by a large amount of data obtained by computer simulation, or it can be obtained through big data.

[0048] Optionally, in one embodiment of the present application, after obtaining the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters, it also includes: predicting the predicted precipitation at the next detection time based on the current climatic conditions; obtaining the predicted urban water consumption based on the urban water use time period corresponding to the next detection time; calculating the predicted theoretical water level based on the predicted precipitation and the predicted urban water consumption; based on the predicted theoretical water level, switching the working state of all preset detection points whose heights are less than the predicted theoretical water level to a dormant state.

[0049] In some embodiments, since it is difficult for a liquid level meter to detect water level data higher than its own set height, and long-term immersion in sewage can easily cause wear, the embodiments of the present application can predict the theoretical water level during the next detection, and switch the working state of the detection point below the theoretical water level to a sleep state in advance, so as to avoid useless detection data affecting the final result and extend the service life of the liquid level meter at the detection point.

[0050] The embodiment of the present application can predict whether it will rain and the approximate amount of rainfall at the next detection moment based on the current climate conditions of the city, and find the corresponding city water consumption based on the next detection moment. Since the time interval between the current detection and the next detection moment is not long, other calculation parameters can directly use the parameters of the current moment to calculate the theoretical water level at the next detection moment, thereby closing the detection points below the theoretical water level at the next detection moment.

[0051] In step S103, at least one preset detection point satisfying preset detection conditions is selected from a plurality of preset detection points based on the theoretical water level, so as to obtain the actual water level of the drainage network based on the water level data of the at least one preset detection point.

[0052] During the actual implementation process, the embodiment of the present application can select multiple detection points located above the theoretical water level and obtain the water level data of each detection point, so as to obtain a more accurate actual water level.

[0053] Among them, since there is an error between the theoretical water temperature and the actual water level, the water level data detected at the detection point near the theoretical water level may not be accurate. The preset detection conditions may include: whether the height difference between the theoretical water level and the detection point is greater than a certain threshold, whether the last quality inspection time of the detection point is less than a certain time threshold, etc.

[0054] Optionally, in one embodiment of the present application, the actual water level of the drainage network is obtained based on water level data of at least one preset detection point, including: determining the number of preset detection points that meet the preset detection conditions; if the number of preset detection points is one, determining that the actual water level is obtained by the water level data of the preset detection points that meet the preset detection conditions; if the number of preset detection points is not one, calculating the height difference between each preset detection point and the theoretical water level, screening out at least one valid preset detection point whose height difference is greater than a preset height threshold, and obtaining the actual water level based on the water level data of at least one valid preset detection point.

[0055] After obtaining the detection points that meet the preset detection conditions, the embodiment of the present application can also determine whether the number of remaining detection points is one.

[0056] If the number of remaining detection points is one, the water level data detected by the detection point can be represented as the actual water level. At this time, since the data source is single and the water level is relatively high, the embodiment of the present application can perform a water level warning.

[0057] If the number of remaining detection points is not one, the embodiment of the present application can obtain multiple water level data. At this time, the embodiment of the present application can calculate the height difference between the detection point and the theoretical water level one by one, and screen out the detection points with smaller height differences to avoid error data collected at detection points that are higher than the theoretical water temperature but lower than the actual water level, and take the average or median value of the water level data obtained from the remaining detection points to obtain a more accurate actual water level.

[0058] Optionally, in one embodiment of the present application, after obtaining the actual water level of the drainage network, it also includes: storing the actual water level in historical water level data to correct the wear coefficient in the next round of actual water level calculation process.

[0059] As a possible implementation method, the embodiment of the present application can store the actual water level obtained at the current moment, so that in the next round of calculation, it can be used as historical data to correct the wear coefficient, so as to continuously increase the calculation accuracy during the actual use of the drainage network. Here, the detection points involved in the embodiment of the present application are explained.

[0060] The detection point involved in the embodiment of the present application can be provided with only a liquid level gauge, or a sealing cover can be provided on the liquid level gauge so that when it is predicted that the water level will overflow the detection point, that is, when the detection point is in a dormant state, the internal liquid level gauge can be protected by the sealing cover.

[0061] In addition, the detection point can also be Figure 2 As shown, in Figure 2 A pressure sensor is installed at the lower end of the structure shown, and a radar probe is installed at the protruding part of the upper end. The height h difference between the pressure sensor and the radar probe is greater than the radar blind area. When installing the equipment, record the height H from the bottom of the pressure sensor to the bottom of the pipe. When the water level is low and does not touch the all-in-one water level meter, the radar probe is used to record the water level. When the water level is high and touches the all-in-one water level meter, it enters the radar probe blind area. At this time, the radar probe records the correct water level value, and the pressure sensor has a pressure change, so the water level is recorded through the pressure sensor. At this time, the pressure value needs to be converted to the water level and the installation height H needs to be added to obtain the actual water level. Figure 2 According to the structure shown, the embodiment of the present application can reduce a large number of detection point settings, and there is no need to switch states according to the prediction results. The actual water level of the drainage network can be determined based on the water level data detected at each detection point.

[0062] According to the water level detection method of the drainage network proposed in the embodiment of the present application, the theoretical water level of the drainage network can be calculated based on the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters, so as to select at least one preset detection point that meets the preset detection conditions from multiple preset detection points according to the theoretical water level, so as to obtain the actual water level of the drainage network based on the water level data of at least one preset detection point, reduce the influence of the liquid level meter's own characteristics on the water level detection result, obtain more accurate water level data of the urban drainage network, and help improve the urban drainage efficiency. Therefore, the technical problem in the related art that it is difficult to accurately obtain the water level data of the urban drainage network due to the influence of the liquid level meter's own design structure, thereby affecting the urban drainage efficiency, is solved.

[0063] Next, the water level detection device for the drainage network proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0064] Figure 3 It is a block diagram of a water level detection device for a drainage network according to an embodiment of the present application.

[0068] The detection module 300 is used to select at least one preset detection point that meets the preset detection conditions from multiple preset detection points based on the theoretical water level, so as to obtain the actual water level of the drainage network based on the water level data of at least one preset detection point.

[0069] Optionally, in one embodiment of the present application, the first calculation module 200 includes: a first acquisition unit, a second acquisition unit, a third acquisition unit, a matching unit and a first calculation unit.

[0070] Among them, the first acquisition unit is used to obtain the current climate conditions and current rainfall of the target city and the current construction status of each water inlet of the drainage network that meets the preset influencing conditions based on the current environmental data.

[0071] The second acquisition unit is used to obtain the operating status of each drainage pump in the drainage network based on the current drainage operation parameters.

[0072] The third acquisition unit is used to estimate the wear coefficient of the drainage network based on the usage time and historical water level data of the drainage network.

[0073] The matching unit is used to match the corresponding urban water use time period based on the current detection time, and use the urban water use time period as an index to match the corresponding urban water use volume in a preset urban water use database.

[0074] The first calculation unit is used to substitute the current climate conditions, current rainfall, current construction status, operation status, wear coefficient and urban water consumption into a pre-constructed theoretical water level calculation formula to obtain a theoretical water level.

[0075] Optionally, in one embodiment of the present application, the water level detection device 10 of the drainage network further includes: a storage module.

[0076] The storage module is used to store the actual water level in the historical water level data so as to correct the wear coefficient in the next round of actual water level calculation process.

[0077] Optionally, in one embodiment of the present application, the water level detection device 10 of the drainage network further includes: a first prediction module, a second prediction module, a second calculation module and a control module.

[0078] Among them, the first prediction module is used to predict the predicted precipitation at the next detection moment based on the current climate conditions.

[0079] The second prediction module is used to obtain the predicted urban water consumption based on the urban water consumption time period corresponding to the next detection moment.

[0080] The second calculation module is used to calculate the predicted theoretical water level based on the predicted precipitation and the predicted urban water consumption.

[0081] The control module is used to switch the working state of all preset detection points whose heights are less than the predicted theoretical water level to a dormant state based on the predicted theoretical water level.

[0082] Optionally, in one embodiment of the present application, the detection module 300 includes: a judgment unit, a determination unit and a second calculation unit.

[0083] The determining unit is used to determine the number of preset detection points that meet preset detection conditions.

[0084] The determination unit is used to determine that the actual water level is obtained by the water level data of the preset detection points that meet the preset detection conditions when the number of the preset detection points is one.

[0085] The second calculation unit is used to calculate the height difference between each preset detection point and the theoretical water level when the number of preset detection points is not one, screen out at least one valid preset detection point whose height difference is greater than the preset height threshold, and obtain the actual water level based on the water level data of at least one valid preset detection point. It should be noted that the aforementioned explanation of the embodiment of the water level detection method for the drainage network is also applicable to the water level detection device for the drainage network of this embodiment, and will not be repeated here.

[0086] According to the water level detection device of the drainage network proposed in the embodiment of the present application, the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters can be used to calculate the theoretical water level of the drainage network based on the current environmental data of the target city, the design parameters of the drainage network and the current drainage operation parameters, so as to select at least one preset detection point that meets the preset detection conditions from multiple preset detection points according to the theoretical water level, so as to obtain the actual water level of the drainage network based on the water level data of at least one preset detection point, reduce the influence of the liquid level meter's own characteristics on the water level detection result, obtain more accurate water level data of the urban drainage network, and help improve the urban drainage efficiency. Therefore, the technical problem in the related art that it is difficult to accurately obtain the water level data of the urban drainage network due to the influence of the liquid level meter's own design structure, thereby affecting the urban drainage efficiency, is solved.
