Description

Waterlogging monitoring equipment and prediction method based on water level rise rate Technical Field

[0001] The present invention relates to the technical field of urban waterlogging prevention and control, and in particular to waterlogging condition monitoring equipment and a prediction method based on the rising speed of accumulated water levels. Background Art

[0002] Urban sunken roads, especially sunken bridges, are seriously flooded. The sunken areas in cities are low-lying and are extremely prone to flooding in the catchment area. This year, the sunken bridge areas in cities have experienced multiple flooding incidents due to short-duration heavy rainfall, posing a huge risk to the safety of life and property.

[0003] Currently, water level monitoring devices, such as CCTV equipment, are installed at flood-prone areas of urban sunken bridges. However, these devices lack the ability to predict water level changes in advance and can only monitor real-time water accumulation in the bridge area. However, due to the small volume of urban sunken areas and the rapid changes in water levels, in the event of a short, heavy rainfall event, by the time conventional water level monitoring equipment detects a flooding event, effective response time has already passed.

[0004] In addition, most current prediction models require a series of modeling parameters, including real-time water level data, historical meteorological data, sunken area terrain parameters, sunken road construction parameters, underlying surface characteristic parameters, and catchment area range. The large amount of data and many influencing factors make the modeling process complex and difficult to operate. Most cities do not have the conditions to build a large mathematical model.

[0005] Summary of the Invention

[0006] To this end, the present invention provides urban flooding monitoring equipment and prediction methods based on the rising speed of accumulated water levels, which can accurately monitor the accumulated water levels in urban sunken areas in real time and predict the evolution trend of accumulated water levels in urban sunken bridges in advance, and the equipment cost is relatively low.

[0007] To solve the above technical problems, the present invention provides a waterlogging monitoring device based on the rising speed of accumulated water level, comprising:

[0008] A monitoring module, the monitoring module comprising a housing mounted on a road to be monitored, a water inlet extending through a side wall of the housing, and water level contact points distributed along the height direction of the side wall of the housing, the water inlet being used to allow accumulated water to flow into the housing when the road is flooded so as to contact the water level contact points at different heights;

[0009] A control system, comprising a control module and a contact module, a storage module and a signal transmission module respectively connected to the control module;

[0010] Wherein, the contact module is configured with the water level contact point, and is used to obtain water level data information sensed by the water level contact point;

[0011] The storage module is used to store the water level data information obtained from the contact module;

[0012] The signal transmission module is used to transmit the water level data information stored in the storage module to the host computer.

[0013] In one embodiment of the present invention, the control system also includes a limiting contact module connected to the control module, and the limiting contact module is configured with a limiting contact point located on the side wall of the shell, and the limiting contact point is located below the water level contact point at the lowest position. The control module has a low-frequency monitoring mode and a high-frequency monitoring mode. When the limiting contact point senses a water level signal and the sensing signal still exists after a preset time, the control module adjusts the low-frequency monitoring mode to a high-frequency monitoring mode.

[0014] In one embodiment of the present invention, it also includes a power supply module electrically connected to the control module, and the shell is divided into a signal transmission compartment, a power supply compartment, a control compartment, a water level contact compartment and a limiting contact compartment. The signal transmission module is accommodated in the signal transmission compartment, the power supply module is accommodated in the power supply compartment, the control module is accommodated in the control compartment, the contact module is accommodated in the water level contact compartment, and the limiting contact module is accommodated in the limiting contact compartment.

[0015] In one embodiment of the present invention, a counterweight bin is further provided in the housing, and a counterweight block is placed in the counterweight bin.

[0016] In one embodiment of the present invention, the shell is a rectangular parallelepiped structure, and its back panel is provided with a mounting buckle; the shell is made of a hard material such as acrylic, PP, ABS or PC, and the inside of the shell is filled with resin.

[0017] In one embodiment of the present invention, the water inlet includes a water level contact hole passing through the side wall of the water level contact bin and a limiting water level contact hole passing through the side wall of the limiting contact bin, the limiting contact point is arranged in the limiting water level contact hole, the contact module and the limiting contact module both include contact panels, the water level contact points are correspondingly arranged on both sides of the contact panel of the contact module, and the water level contact point on one side is correspondingly arranged at the contact hole.

[0018] In one embodiment of the present invention, the water level contact points include two rows arranged in parallel, and the water level contact points in the two rows are spaced apart in the height direction.

[0019] A method for predicting urban flooding based on the rate of water level rise, characterized in that, using the monitoring device, the method comprises:

[0020] When the limit contact point senses a water level signal and the sensing signal still exists after a preset time, the control module adjusts the low-frequency monitoring mode to the high-frequency monitoring mode;

[0021] The water level data information is set as an array (X, t), where X is the number of the water level contact points from bottom to top, X=1, 2, 3..., X is an integer not less than 1, and t is the monitoring time;

[0022] After receiving the arrays, the host computer performs fitting by the exponential sliding average method to obtain a water level prediction curve;

[0023] The fitting degree of the exponential moving average method is evaluated by introducing the mean square error formula to correct the water level prediction curve.

[0024] In one embodiment of the present invention, the exponential sliding average method is used to fit the water level prediction curve, including obtaining the predicted value S at time t according to the following formula: t :

[0025] Where: S t represents the predicted value at time t; X t represents the actual observation value at time t; α represents the smoothing parameter; S0 represents the initialization parameter of the recursive expansion.

[0026] In one embodiment of the present invention, the evaluation of the degree of fit of the exponential moving average method by introducing a mean square error formula to correct the water level prediction curve includes:

[0027] Calculate the mean square error (MSE):

[0028] When the MSE value is greater than a preset threshold, the exponential sliding average method is repeated until the MSN is less than the preset threshold.

[0029] The above technical solution of the present invention has the following advantages over the prior art:

[0030] The waterlogging condition monitoring equipment and prediction method based on the rising speed of accumulated water level described in the present invention can monitor the accumulated water level in the sunken area of ​​the city in real time, and predict the evolution trend of the accumulated water level in the sunken bridge of the city in advance, and predict the corresponding time of the accumulated water depth that may endanger the safety of pedestrians and vehicles within the specific sunken bridge area, thereby providing waterlogging condition information for emergency management, drainage and flood prevention, and traffic management.

[0031] The water level monitoring equipment has a design to prevent water level misjudgment, variable frequency monitoring function, automatic uploading and storage of water level time data, and its own linear power supply; the upper computer classifies the data uploaded by the water level monitoring equipment and uses the multi-level exponential sliding average method to calculate the data and obtain the predicted data under the target conditions.

[0032] The water level monitoring device is a vertically tall cuboid with a rectangular bottom. The back panel features mounting clips that allow the device to be placed on a horizontal surface and then fixed to a pole or wall. The device's outer shell is made of hard materials such as acrylic, PP, ABS, and PC, and is sealed at the seams. The interior is filled with resin to protect the circuit board and contact points from short circuits and misjudgments caused by air humidity and rainwater seepage. The device is equipped with a counterweight compartment with counterweight blocks placed inside to increase the weight of the bottom of the device, resist the impact of road rain, and prevent the risk of the device tipping over or floating due to installation problems. It carries its own linear power supply with an active power-saving function, and a pre-set detachable structure on the top of the outer shell allows construction or management personnel to replace the battery. The battery has a nominal voltage of 3.7V and can last for 2 years in low-frequency operating mode and 6 months in continuous high-frequency mode.

[0033] This water level monitoring device utilizes bilaterally aligned contact sensing points, shortening the distance between adjacent monitoring points and improving accuracy. Depending on the contact point layout, the device achieves detection accuracy of ±4mm and eliminates the effects of water temperature, water quality, and water debris.

[0034] The water level monitoring device has a variable frequency function and can operate in two modes: high-frequency and low-frequency, depending on whether the water level is above the limit contact point. In the high-frequency mode, the monitoring frequency is further adjusted based on the water level and the rate of change of the water level.

[0035] The water level monitoring equipment has strong anti-interference (wave and splashing liquid identification and elimination) capabilities. The water level contact points of the water level monitoring equipment are respectively arranged on both sides of the contact plate. When one side of the monitoring equipment senses a water accumulation signal, the equipment will not trigger the corresponding program and instructions. Only when both sides of the contact plate sense a water accumulation signal can the relevant instructions be triggered. This design can avoid the situation where road vehicles pass through flooded roads and generate waves or accidentally contact water bodies, resulting in misjudgment of the water level height at the water level contact point on one side.

[0036] This water level monitoring device features data transmission and signal transmission capabilities. A coupled signal upload and download mechanism is incorporated into the device, enabling communication between the water level monitoring device and a host computer. The device combines the monitored water level data and the corresponding time into an array format and transmits it to the host computer in real time. The data calculation platform calculates the time when the water level in the sunken bridge area reaches the corresponding alarm level or other threshold. This data is then transmitted to emergency management, drainage and flood control, and traffic management departments, and then sent down to the water level monitoring device to issue an alarm signal. The platform also features a data export interface, located within the battery compartment, which can be periodically exported and stored by management and construction personnel.

[0037] By adopting the multi-level exponential moving average method, which is a business indicator forecasting method widely used in commercial activities, the multi-level exponential moving average method is used to predict the water level change trend on the basis of the exponential moving average method. It pays more attention to the calculation weight of the recent water level data and reduces the calculation weight of the long-term water level. Under the premise of reducing the impact of outliers on the smoothing results, the changes in data trends are faster, and the prediction data judgment method is added to simultaneously demonstrate the credibility of the prediction results.

[0038] This prediction method does not require basic data and rainfall data of the bridge area, does not use construction data of the monitoring area such as pipeline parameters, catchment area, digital elevation, etc., and does not need to collect historical meteorological data of the monitoring area such as rainfall, rainfall type, wind field, temperature and other parameters. It greatly reduces the workload of building a prediction model, has low cost and small data volume, and is suitable for wide promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0051] 1 , a waterlogging monitoring device based on the rising speed of accumulated water level includes:

[0052] A monitoring module, comprising a housing 008 mounted on the road to be monitored, a water inlet extending through a sidewall of the housing 008, and water level contact points 009 distributed along the height direction of the sidewall of the housing 008. The water inlet is used to allow water to flow into the housing 008 when the road is flooded, so as to contact the water level contact points 009 at different heights.

[0053] A control system, comprising a control module and a contact module, a storage module and a signal transmission module respectively connected to the control module;

[0054] Wherein, the contact module is configured with the water level contact point 009, and is used to obtain the water level data information sensed by the water level contact point 009;

[0055] The storage module is used to store the water level data information obtained from the contact module;

[0056] The signal transmission module is used to transmit the water level data information stored in the storage module to the host computer.

[0057] As shown in FIG2 , the control system further includes a limiting contact module connected to the control module. It is understood that the storage module can also store water level data information obtained from the limiting contact module and transmit it to the host computer through the signal transmission module. The limiting contact module is configured with a limiting contact point 010 located on the side wall of the housing 008. The limiting contact point 010 is located below the lowest water level contact point 009. The control module includes a frequency conversion module with a low-frequency monitoring mode and a high-frequency monitoring mode. When the limiting contact point 010 senses a water level signal and the sensing signal still exists after a preset time (10 seconds), the control module adjusts the low-frequency monitoring mode to a high-frequency monitoring mode. In this embodiment, the monitoring frequency of the low-frequency monitoring mode is 1 hour / time, and the monitoring frequency of the high-frequency monitoring mode is 5 seconds / time.

[0058] 3 to 5 , the device also includes a power module electrically connected to the control module. The housing 008 is divided into a signal transmission compartment 003, a power supply compartment 005, a control compartment 001, a water level contact compartment 002, and a limit contact compartment 004. The signal transmission module is housed in the signal transmission compartment 003, the power supply module is housed in the power supply compartment 005, the control module is housed in the control compartment 001, the contact module is housed in the water level contact compartment 002, and the limit contact module is housed in the limit contact compartment 004. These can be installed using snaps 007. A counterweight compartment 006 is also provided within the housing 008. Counterweight blocks are housed within the counterweight compartment 006 to increase the overall bottom weight of the device, resisting the impact of road rain and preventing the risk of the device tipping or floating due to installation problems.

[0059] Among them, the control module adopts a microcontroller, and in this embodiment, the STM32L15CBT6A module is adopted. Its structure is shown in Figure 5, including a control circuit board, a clock module, a signal module and an alarm module; the contact module adopts an electronic water gauge, and a TC401 inductive digital water level sensor can be adopted; the storage module adopts the SN74HC165PWR mobile register, the signal transmission module adopts the TP8485E-SR module, and the frequency conversion module adopts the SY6280AAC module built into the control module, which can adjust the interval of transmitted data between high-frequency monitoring mode and low-frequency monitoring mode.

[0060] As shown in Figure 1, the shell 008 has a rectangular structure, and its back panel is provided with a mounting clip 011, which can meet the requirements of fixing the monitoring equipment on a pole or wall in the vertical direction along the length direction after being placed on a horizontal ground; the shell 008 is made of hard materials such as acrylic (Acrylic), polypropylene (PP, Polypropylene), acrylonitrile butadiene styrene copolymer (ABS, Acrylonitrile Butadiene Styrene) and polycarbonate (PC, Polycarbonate), and the interior of the shell 008 is filled with resin glue. The shell 008 is sealed at the seams to protect the internal circuit board and the contact points from short circuits and misjudgments due to air humidity and rainwater leakage.

[0061] The water inlet includes a water level contact hole 013 that passes through the side wall of the water level contact chamber 002 and a limiting water level contact hole 014 that passes through the side wall of the limiting contact chamber 004. The limiting contact point 010 is set in the limiting water level contact hole 014. It can be understood that there is a gap between the water level contact point and the limiting contact point and the matching hole to allow water to enter. The contact module and the limiting contact module both include a contact panel. The water level contact point 009 is correspondingly set on both sides of the contact panel of the contact module (two opposite electronic water gauges can also be set), and the water level contact point 009 on one side is correspondingly set to the contact hole. When one side of the monitoring device senses a water accumulation signal, the device will not trigger the corresponding program and instructions. Only when both sides of the contact panel sense a water accumulation signal can the relevant instructions be triggered to prevent pedestrians and moving vehicles from generating waves and water splashing to the contact point during road water accumulation, affecting the monitoring accuracy and causing distortion of the water level monitoring results.

[0062] The water level contact points 009 are arranged in two parallel rows, spaced apart in height. This shortens the distance between adjacent water level monitoring points and improves the accuracy of the water level monitoring equipment. The equipment's detection accuracy, based on the contact point layout, reaches ±4mm, and it can eliminate the influence of water temperature, water quality, and water debris.

[0063] 6 , this embodiment further provides a method for predicting urban flooding based on the rising speed of accumulated water levels using the above-mentioned monitoring equipment, including:

[0064] S1. When the limiting contact point 010 senses a water level signal and the sensing signal still exists after a preset time, the control module adjusts the low-frequency monitoring mode to the high-frequency monitoring mode;

[0065] S2. Set the water level data information as an array (X, t), where X is the bottom-up number of the water level contact point 009, X=1, 2, 3..., X is an integer not less than 1, and t is the monitoring time;

[0066] S3. After receiving the arrays, the host computer performs fitting using an exponential sliding average method to obtain a water level prediction curve;

[0067] The predicted value S at time t is obtained according to the following formula: t : S t =αX t +(1-α)S t-1

[0068] Right now:

[0069] Where: S t represents the predicted value at time t; X t represents the actual observation value at time t; α represents the smoothing parameter; S0 represents the initialization parameter of the recursive expansion.

[0070] S4. Evaluate the fitting degree of the exponential moving average method by introducing the mean square error formula to correct the water level prediction curve.

[0071] Calculate the mean square error (MSE):

[0072] When MSE is greater than 1, it indicates that the model coupling effect is poor, and further correction is performed using the quadratic exponential smoothing method. If the MSE index is still greater than 1 after correction using the quadratic exponential smoothing method, further correction is performed using the cubic exponential smoothing method, and so on, until the MSE index is less than 0.1. When MSE is less than 0.1, it indicates that the model fitting effect is satisfactory, and the next moment data can be introduced for calculation.

[0073] This prediction method continuously enriches the basic database of the exponential sliding average method on the premise of considering the time series weight. More basic data can make the predicted value calculated by the exponential sliding closer to the measured value. Under the premise of setting the alarm water level threshold, the moment when the water level in the bridge area reaches the threshold is obtained in the fastest way, which also provides a time basis for the emergency management and drainage and flood prevention departments to take emergency measures.

[0074] In the high-frequency monitoring mode, when the water level changes to the adjacent contact point below the current water level contact point 009, under the premise of setting a safe water level threshold, the moment when the water in the bridge area recedes to the safe water level threshold is obtained in the fastest way, which also provides a time basis for the emergency management and drainage and flood prevention departments to lift the alarm.

[0075] Based on the water level increase rate in the sunken bridge area of ​​the city (calculated by the time interval between the contact points of the electronic water gauge at different heights, that is, the point interval distance / point number difference), the system can be predicted to adjust the monitoring frequency and the corresponding warning level in a timely manner. The recommended values ​​are shown in Table 1.

Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
