Description

Technical Field

[0001] This application relates to the technical field of engineering monitoring, specifically to a method, device, and electronic equipment for real-time monitoring of riverbed scour. Background Technology

[0002] Man-made canals are artificially constructed waterway systems, typically dug, laid, or built by hand, used to guide, store, distribute, and control water resources to meet needs such as irrigation, water supply, drainage, and navigation. These canals can be underground or above ground, and their design and construction take into account the direction of water flow, slope, capacity, and surrounding environmental factors, providing an important means of water resource management and utilization for human activities and agricultural production.

[0003] Currently, man-made irrigation canals are greatly affected by water flow velocity; both excessively fast and slow flow rates can lead to safety accidents. High-speed water flow easily erodes the bottom and sidewalls of the canal, potentially causing pits at the bottom and landslides on the slopes. Conversely, slow-speed water flow struggles to carry large particles of sediment, preventing their deposition and the formation of silt. This can reduce the canal's capacity or even cause blockages.

[0004] Therefore, a method is needed to monitor canals in order to determine whether a safety incident may occur in the canal bed. Summary of the Invention

[0005] This application provides a method, device, and electronic equipment for real-time monitoring of riverbed scour, which can monitor waterways and determine whether a safety accident may occur in the riverbed.

[0006] This application provides a method for real-time monitoring of riverbed scour, the method being applied to a server and comprising: Obtain the water flow velocity of each water layer in the preset riverbed; The target water flow velocity of the target water area is obtained, wherein the target water area is any layer of water area in a multi-layer water area, and the target water flow velocity is the water flow velocity corresponding to the target water area among multiple water flow velocities; Based on the target water flow velocity, determine the depth variation value of the riverbed soil layer in the preset riverbed; Determine whether the depth change value is greater than a preset threshold. If the depth change value is greater than the preset threshold, output a warning message.

[0007] By employing the above technical solution, the server uses the water flow velocity of a preset multi-layered riverbed as data to predict the depth change of the riverbed soil layer. When the depth change of the riverbed soil layer exceeds a preset threshold, it indicates that the water flow velocity is too fast, causing the riverbed soil layer to be largely eroded away, which may lead to excessive erosion of the riverbed bottom or sidewalls. The server then outputs an early warning, notifying relevant personnel of this information, thereby monitoring the canal and assisting in determining whether a safety accident may occur in the canal bed.

[0008] Optionally, obtaining the water flow velocity of each water layer in the preset riverbed specifically includes: Determine the target cross section, and cut off the target water area in the direction perpendicular to the water flow direction. The cut-off position is located at the setting position of the ultrasonic flow meter in the preset riverbed. The resulting cross section is the target cross section. Obtain multiple sub-velocities at different locations of the target cross section; The target water flow velocity is obtained by averaging the values ​​of the multiple sub-flow velocities.

[0009] By employing the above technical solution, flow velocity is measured at multiple locations along the cross-section of the channel, and the target flow velocity of the target water area is calculated based on the sub-flow velocities at different locations along the target cross-section. This allows for more accurate capture of changes in flow velocity, especially when there is a non-uniform velocity distribution across the cross-section.

[0010] Optionally, after obtaining the target water flow velocity in the target water area, the method further includes: The soil properties, thickness, and cohesion of the riverbed soil layer were obtained. Based on a preset correspondence, the critical flow velocity of the soil layer corresponding to the soil quality, soil layer thickness and soil layer cohesion is obtained. Obtain the critical flow velocity of the preset riverbed, where the critical flow velocity is the flow velocity value that the preset riverbed can withstand. Based on the critical flow velocity of the soil layer and the critical flow velocity of the riverbed, the safe flow velocity range of the water flow in the preset riverbed is determined.

[0011] By employing the aforementioned technical solution, and by acquiring parameters such as soil properties, soil layer thickness, and soil cohesion, and combining them with preset correlations, the critical flow velocity of the soil layer can be calculated. This allows for the assessment of the soil layer's stability under different flow velocities, i.e., the maximum flow velocity the soil layer can withstand. When the water flow velocity is less than the critical flow velocity of the soil layer, the riverbed soil layer may not be able to be eroded away by the water flow, resulting in the accumulation of silt in the riverbed.

[0012] Optionally, after determining the safe flow velocity range of the water flow within the preset riverbed based on the critical flow velocity of the soil layer and the critical flow velocity of the riverbed, the method further includes: The first velocity reduction and the second velocity reduction are determined based on the number of layers the target water area is located in the multi-layer water area. The first critical velocity is obtained based on the critical velocity of the soil layer and the first velocity reduction. The second critical velocity is obtained based on the critical velocity of the riverbed and the second velocity reduction. Based on the first critical flow velocity and the second critical flow velocity, the target flow velocity range of the water flow in the target water area is obtained.

[0013] By employing the above technical solution, a first velocity reduction and a second velocity reduction are determined based on the layer in which different water bodies are located. These velocity reductions take into account the different natural flow velocities of water at different heights. Based on parameters such as the critical velocity of the soil layer, the critical velocity of the riverbed, and the velocity reduction, the first critical velocity and the second critical velocity are calculated. Then, the target velocity range within the target water body is determined, which helps to more accurately estimate the safe velocity range within the target water body.

[0014] Optionally, before determining the depth variation of the riverbed soil layer based on the target water flow velocity, the method further includes: Determine whether the target water flow velocity is greater than or equal to the first critical flow velocity, and whether the target water flow velocity is less than the second critical flow velocity, thereby determining whether the target water flow velocity is within the target flow velocity range; If the target water flow velocity is greater than or equal to the first critical flow velocity, and the target water flow velocity is less than the second critical flow velocity, then the target water flow velocity is within the target flow velocity range. If the target water flow velocity is within the target flow velocity range, then the subsequent calculation of the depth change value is stopped.

[0015] By employing the above technical solution, real-time water flow safety assessment is achieved by determining whether the target water flow velocity is within the target velocity range. If the target water flow velocity is within the range, it indicates that the current water flow condition is acceptable, and no further depth change calculation is required. Simultaneously, if the target water flow velocity is within the target velocity range, it indicates that the current water flow condition is normal, and no further processing is needed. This reduces false alarms and improves the accuracy and reliability of warnings.

[0016] Optionally, before determining the depth variation of the riverbed soil layer based on the target water flow velocity, the method further includes: The system determines whether the target water flow velocity is less than the first critical flow velocity, or whether the target water flow velocity is greater than or equal to the second critical flow velocity, thereby determining whether the target water flow velocity is not within the target flow velocity range. If the target water flow velocity is less than the first critical flow velocity, or the target water flow velocity is greater than or equal to the second critical flow velocity, then it is determined that the target water flow velocity is not within the target flow velocity range. If it is determined that the target water flow velocity is not within the target flow velocity range, then the depth change value is obtained.

[0017] By employing the above technical solution, real-time water flow safety assessment is achieved by determining whether the target water flow velocity is outside the target velocity range. If the target water flow velocity exceeds the range, potential safety issues may exist, requiring further analysis and countermeasures.

[0018] A second aspect of this application provides a real-time riverbed scour monitoring device, the device being a server, comprising an acquisition module, a processing module, and a judgment module, wherein: The acquisition module is used to acquire the water flow velocity of each layer of the preset riverbed; The acquisition module is used to acquire the target water flow velocity of the target water area, wherein the target water area is any layer of water area in a multi-layer water area, and the target water flow velocity is the water flow velocity corresponding to the target water area among multiple water flow velocities. The processing module is used to determine the depth variation value of the riverbed soil layer of the preset riverbed based on the target water flow velocity. The judgment module is used to determine whether the depth change value is greater than a preset threshold. If the depth change value is greater than the preset threshold, an early warning prompt is output.

[0019] A third aspect of this application provides an electronic device including a processor, a memory, a user interface, and a network interface, wherein the memory is used to store instructions, the user interface and the network interface are both used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the electronic device to perform the method as described in any of the foregoing.

[0020] A fourth aspect of this application provides a computer-readable storage medium storing instructions that, when executed, perform the method described in any of the preceding descriptions.

[0021] In summary, one or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. The server uses the water flow velocity of a preset multi-level riverbed as data to predict the depth change of the riverbed soil layer. When the depth change of the riverbed soil layer exceeds a preset threshold, it indicates that the water flow velocity is too fast, causing the riverbed soil layer to be largely eroded away, which may lead to excessive erosion of the bottom or sidewalls of the riverbed. The server then outputs an early warning, notifying relevant personnel of this information, thereby enabling monitoring of the canal and assisting in determining whether a safety hazard may occur in the canal bed.

[0022] 2. By acquiring parameters such as soil properties, soil layer thickness, and soil cohesion, and combining them with preset correlations, the critical flow velocity of the soil layer is calculated. This allows for the assessment of the soil layer's stability under different flow velocities, i.e., the maximum flow velocity the soil layer can withstand. When the water flow velocity is less than the critical flow velocity of the soil layer, the riverbed soil may not be able to be eroded away by the water flow, resulting in the accumulation of silt in the riverbed.

[0023] 3. Real-time water flow safety assessment is achieved by determining whether the target water flow velocity is within the target velocity range. If the target water flow velocity is within the range, the current water flow condition is acceptable, and no further depth change calculation is needed. Simultaneously, if the target water flow velocity is within the target velocity range, the current water flow condition is normal, and no further processing is required. This reduces false alarms and improves the accuracy and reliability of warnings. Real-time water flow safety assessment is achieved by determining whether the target water flow velocity is outside the target velocity range. If the target water flow velocity exceeds the range, there may be potential safety issues, requiring further analysis and measures. Attached Figure Description

[0029] Man-made canals are artificially constructed waterway systems, typically dug, laid, or built by hand, used to guide, store, distribute, and control water resources to meet needs such as irrigation, water supply, drainage, and navigation. These canals can be underground or above ground, and their design and construction take into account the direction of water flow, slope, capacity, and surrounding environmental factors, providing an important means of water resource management and utilization for human activities and agricultural production.

[0030] Currently, man-made irrigation canals are greatly affected by water flow velocity; both excessively fast and slow flow rates can lead to safety accidents. High-speed water flow easily erodes the bottom and sidewalls of the canal, potentially causing pits at the bottom and landslides on the slopes. Conversely, slow-speed water flow struggles to carry large particles of sediment, preventing their deposition and the formation of silt. This can reduce the canal's capacity or even cause blockages.

[0031] Therefore, a method is needed to monitor canals in order to determine whether a safety incident may occur in the canal bed.

[0032] This embodiment discloses a method for real-time monitoring of riverbed scour, referring to... Figure 1 This includes the following steps S110-S140: S110, obtain the water flow velocity of each water layer of the preset riverbed.

[0033] The real-time riverbed scour monitoring method disclosed in this application is applied to a server. The server includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, and PCs (Personal Computers), and can also be a backend server running a real-time riverbed scour monitoring method. The server can be implemented using a standalone server or a server cluster composed of multiple servers.

[0034] For pre-designed riverbeds in artificial canals requiring scour monitoring, ultrasonic flow meters are installed on the side of the pre-designated riverbed, ensuring the sensor is correctly positioned in the direction of water flow. The installation location must consider the uniformity of flow velocity distribution and the properties of the fluid. Before using an ultrasonic flow meter, calibration is typically required to ensure measurement accuracy. Calibration can be performed by comparing the flow meter with a standard device of known flow velocity. Setting appropriate parameters in the ultrasonic flow meter, such as fluid type and channel size, will help the flow meter accurately calculate the flow velocity. The ultrasonic flow meter emits ultrasonic signals through its sensor; these signals propagate along the water flow and are reflected back by particles in the fluid. The time difference between transmission and reception of the ultrasonic signal is measured. Since water velocity affects signal propagation time, this time difference can be used to calculate the water velocity. After measuring the water velocity, the ultrasonic flow meter transmits the velocity data to a server.

[0035] S120, obtain the target water flow velocity in the target water area.

[0036] For any given section of riverbed, the water flow velocity will vary at different elevations. Therefore, it is necessary to measure the water flow velocity at multiple elevations. This requires using an ultrasonic flow meter to measure the water flow velocity at multiple elevations, integrating the data to obtain the river flow rate, and then calculating an average value as the water flow velocity for that section.

[0037] Specifically, refer to Figure 2 The preset riverbed is divided into multiple water areas from high to low, preferably four layers, including target water area a, target water area b, target water area c, and target water area d. Taking any one of these target water areas as an example, a section of the target water area is cut perpendicular to the water flow direction, with the cut-off point located at the position where the ultrasonic flow meter is set on the preset riverbed. This section is the target section, and therefore the ultrasonic flow meter is located at the target section. The water flow velocity at different positions on the target section is measured using the ultrasonic flow meter and labeled as sub-velocities. The average value of the multiple sub-velocities of the target water area is calculated to obtain the target water flow velocity of the target water area.

[0038] By measuring flow velocity at multiple locations along the cross-section of the channel, and calculating the target flow velocity of the target water area based on the sub-flow velocities at different locations along the target cross-section, the system can more accurately capture changes in flow velocity, especially when there is a non-uniform velocity distribution across the cross-section.

[0039] Prior to this, a series of experiments were needed to test the optimal water flow velocity required to just wash away the riverbed soil under different soil types, thicknesses, and cohesion levels. During the experiments, different soil layers were laid on the riverbed, and the flow velocity was controlled by adjusting the water volume. The approximate water flow velocity required to just wash away the riverbed soil was measured, i.e., the critical velocity for the soil layer. Subsequently, a correlation was established between different soil types, soil layer thicknesses, soil cohesion levels, and critical velocities for different soil layers, yielding a pre-defined correlation.

[0040] Next, to determine whether the target water flow velocity is too fast or too slow, the pre-designed riverbed is sampled and tested. Appropriate soil survey methods, such as soil probes, are used to measure the thickness of the riverbed soil layer, which is determined by analyzing borehole samples or probe data. Then, the soil cohesion is measured through laboratory testing. Cohesion is a physical property of soil and can be obtained through various testing methods, such as shear tests.

[0041] Based on the established pre-defined correspondences, the critical flow velocity of the soil layer corresponding to the soil quality, soil layer thickness, and soil layer cohesion of the current riverbed is determined. Simultaneously, since the pre-defined riverbed is a section of an artificial canal, the critical flow velocity of the pre-defined riverbed is calculated using relevant fluid mechanics theories or experimental data, based on the material properties, slope, and other parameters of the pre-defined riverbed. The critical flow velocity value represents the maximum water flow velocity that the pre-defined riverbed can withstand without causing riverbed erosion or deformation. Finally, using the critical flow velocity of the soil layer and the critical flow velocity of the riverbed as two endpoints, the safe flow velocity range within the pre-defined riverbed is obtained. For example, if the critical flow velocity of the soil layer is e and the critical flow velocity of the riverbed is f, then the safe flow velocity range is [e, f].

[0042] By acquiring parameters such as soil properties, soil layer thickness, and soil cohesion, and combining them with preset correlations, the critical flow velocity of the soil layer can be calculated. This allows for the assessment of the stability of the soil layer under different flow velocities, i.e., the maximum flow velocity that the soil layer can withstand. When the water flow velocity is less than the critical flow velocity of the soil layer, the riverbed soil layer may not be able to be eroded away by the water flow, resulting in the accumulation of silt in the riverbed.

[0043] Furthermore, it is necessary to refine the safe flow velocity range by considering factors such as the location of the water body, the influence of multiple water layers, and velocity reduction. This helps to more accurately determine the appropriate velocity range for the water flow, thereby ensuring the stability of the soil and riverbed, reducing the impact of the water flow on the riverbed, and ensuring the safety of man-made canals.

[0044] Since the water flow within the pre-defined riverbed is divided into multiple water areas, the values ​​at both ends of the safe flow velocity need to be reduced according to the target water area of ​​different layers. The first and second velocity reductions typically refer to the decrease in water flow velocity caused by factors such as topography and friction. More complex fluid dynamic factors, such as turbulence and eddies, may also be involved. These reductions can be estimated through experiments, numerical simulations, and other methods. These reductions will vary within different layers. The specific values ​​of the first and second velocity reductions need to be set according to the actual conditions of different riverbeds; this embodiment does not impose specific limitations.

[0045] Based on the first velocity reduction, the critical velocity of the soil layer is reduced to obtain the first critical velocity. Based on the second velocity reduction, the critical velocity of the riverbed is reduced to obtain the second critical velocity. Finally, the first critical velocity is used as the two endpoints to obtain the target velocity range of the water flow in the target water area. For example, if the critical velocity of the soil layer is e, the critical velocity of the riverbed is f, the first velocity reduction is g, and the second velocity reduction is h, then the target velocity range is [eg, fh].

[0046] Based on the different layers of the water body, a first velocity reduction and a second velocity reduction are determined. These velocity reductions take into account the different natural flow velocities of water at different heights. Based on parameters such as the critical velocity of the soil layer, the critical velocity of the riverbed, and the velocity reduction, the first critical velocity and the second critical velocity are calculated. Then, the target velocity range within the target water body is determined, which helps to more accurately estimate the safe velocity range within the target water body.

[0047] Next, it is determined whether the measured target flow velocity meets the following two conditions: whether the target flow velocity is greater than or equal to the first critical velocity, and whether the target flow velocity is less than the second critical velocity. If the target flow velocity meets both conditions, it can be determined that the target flow velocity is within the target velocity range. This means that the flow velocity is within a certain range and can flow while carrying away the riverbed soil and maintaining riverbed stability. If the target flow velocity has been determined to be within the target velocity range, then the subsequent calculation of depth change values ​​can be terminated. This is because the target flow velocity has already met the requirements of safety and stability, and further analysis and calculation of depth change are not required.

[0048] Real-time water flow safety assessment is achieved by determining whether the target water flow velocity is within the target velocity range. If the target water flow velocity is within the range, it indicates that the current water flow condition is acceptable, and no further depth change calculation is required. Simultaneously, if the target water flow velocity is within the target velocity range, it indicates that the current water flow condition is normal, and no further processing is needed. This reduces false alarms and improves the accuracy and reliability of warnings.

[0049] Similarly, the measured target flow velocity is determined to meet either of the following two conditions: First, is the target flow velocity less than the first critical velocity? Second, is the target flow velocity greater than or equal to the second critical velocity? If the target flow velocity meets either of these conditions, it can be determined that the target flow velocity is not within the target velocity range. This means that the flow velocity may be too slow or too rapid. Too slow a flow may prevent the riverbed soil from being carried away, leading to silt accumulation. Too rapid a flow may erode the bottom and sidewalls of the canal, potentially causing pits at the bottom and slope collapses. If it is confirmed that the target flow velocity is not within the target velocity range, the corresponding depth change value is obtained accordingly. By determining whether the target flow velocity is outside the target velocity range, real-time water flow safety assessment is achieved. If the target flow velocity exceeds the range, there may be potential safety issues requiring further analysis and measures.

[0050] S130, based on the target water flow velocity, determines the depth variation value of the riverbed soil layer in the preset riverbed.

[0051] S140, determine whether the depth change value is greater than the preset threshold. If the depth change value is greater than the preset threshold, output an early warning message.

[0052] After calculating the depth change value of the riverbed soil layer, it is determined whether the depth change value exceeds a preset threshold. This preset threshold is set based on the initial thickness of the riverbed soil layer, and its value is slightly smaller than the initial thickness. When the thickness change value approaches the preset threshold, it indicates that the riverbed soil layer has been largely eroded away. If the thickness change value is still less than or equal to the preset threshold, it indicates that the riverbed soil layer has not been completely eroded away, and no warning is needed. If the depth change value exceeds the preset threshold, it indicates that the riverbed soil layer has been largely eroded away, and the server outputs a warning message. The warning message can be in the form of text message, SMS, or voice, to inform relevant personnel of the risk of a safety accident in the canal / riverbed.

[0053] By employing the above technical solution, the server uses the water flow velocity of a preset multi-layered riverbed as data to predict the depth change of the riverbed soil layer. When the depth change of the riverbed soil layer exceeds a preset threshold, it indicates that the water flow velocity is too fast, causing the riverbed soil layer to be largely eroded away, which may lead to excessive erosion of the riverbed bottom or sidewalls. The server then outputs an early warning, notifying relevant personnel of this information, thereby monitoring the canal and assisting in determining whether a safety accident may occur in the canal bed.

[0054] This embodiment also discloses a real-time riverbed scour monitoring device, characterized in that the device is a server, as described above. Figure 4 It includes an acquisition module 401, a processing module 402, and a judgment module 403, wherein: The acquisition module 401 is used to acquire the water flow velocity of each layer of the preset riverbed.

[0055] The acquisition module 401 is used to acquire the target water flow velocity of the target water area.

[0057] The judgment module 403 is used to determine whether the depth change value is greater than a preset threshold. If the depth change value is greater than the preset threshold, an early warning prompt will be output.

[0058] In one possible implementation, the processing module 402 is used to determine the target cross section, intercept the target water area in the direction perpendicular to the water flow direction, and the interception position is located at the setting position of the ultrasonic flow meter in the preset riverbed, and the resulting cross section is the target cross section.

[0063] The acquisition module 401 is used to acquire the critical flow velocity of the preset riverbed, which is the flow velocity value that the preset riverbed can withstand.

[0064] The processing module 402 is used to determine the safe flow velocity range of water flow in the preset riverbed based on the critical flow velocity of the soil layer and the critical flow velocity of the riverbed.

[0065] In one possible implementation, the determination module 403 is used to determine the first velocity reduction and the second velocity reduction based on the number of layers in the multi-layer water body where the target water body is located.

[0066] Processing module 402 is used to obtain the first critical velocity based on the critical velocity of the soil layer and the first velocity reduction.

[0068] The processing module 402 is used to obtain the target flow velocity range of the water flow in the target water area based on the first critical flow velocity and the second critical flow velocity.

[0069] In one possible implementation, the determination module 403 is used to determine whether the target water flow velocity is greater than or equal to the first critical flow velocity, and whether the target water flow velocity is less than the second critical flow velocity, thereby determining whether the target water flow velocity is within the target flow velocity range.

[0070] The judgment module 403 is used to determine if the target water flow velocity is within the target flow velocity range if the target water flow velocity is greater than or equal to the first critical flow velocity and less than the second critical flow velocity.

[0071] The judgment module 403 is used to stop calculating the depth change value if the target water flow velocity is within the target flow velocity range.

[0072] In one possible implementation, the determination module 403 is used to determine whether the target water flow velocity is less than the first critical flow velocity, or whether the target water flow velocity is greater than or equal to the second critical flow velocity, thereby determining whether the target water flow velocity is not within the target flow velocity range.
