Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0033] An embodiment of the present application provides an offshore wind power foundation scour monitoring and early warning identification system. As shown in FIG1 , the offshore wind power foundation scour monitoring and early warning identification system 1 includes: a data acquisition module 11 , a data processing and training module 12 , and a monitoring and early warning identification module 13 .
[0034] The data processing and training module 12 is connected to the data acquisition module 11 and the monitoring and early warning identification module 13 respectively.
[0035] It should be understood that the system may also include other devices and equipment.
[0036] The monitoring and early warning identification module 13 includes a first monitoring and early warning identification submodule 131 and a second monitoring and early warning identification submodule 132 ; the first monitoring and early warning identification submodule 131 includes a data processing submodule 1311 .
[0037] The first monitoring and early warning identification submodule 131 is a real-time monitoring module; the second monitoring and early warning identification submodule 132 is a wireless remote monitoring module.
[0038] Furthermore, the function of each device in the above system is described.
[0039] Specifically, the data acquisition module 11 is used to obtain a preset scour warning level dataset and a historical scour measurement dataset corresponding to the offshore wind power foundation, and the preset scour warning level dataset and the historical scour measurement dataset are sent to the data processing and training module 12 .
[0040] After the data processing and training module 14 receives the preset scour warning level data set and the historical scour measurement data set, it first calculates at least one scour measurement average value based on the historical scour measurement data set; secondly, based on each scour measurement average value, the corresponding scour warning level is determined in the preset scour warning level data set, that is, the correspondence between each scour measurement average value and each scour warning level can be obtained; finally, based on the correspondence and the historical scour measurement data set, after training with a preset recurrent neural network algorithm (RNN neural network algorithm), the target recurrent neural network model can be obtained, and the target recurrent neural network model is sent to the monitoring and warning identification module 13.
[0041] Specifically, a good algorithm model, namely the target recurrent neural network model, is determined by continuously training the algorithm model and finding the optimal parameters in different sensor signal modeling stages.
[0042] When a scour disaster occurs, the monitoring and early warning identification module 13 can directly use the received target recurrent neural network model to monitor and identify the scour situation corresponding to the offshore wind power foundation to obtain a scour early warning level.
[0043] First, when a scour disaster occurs, the data acquisition module 11 obtains at least one scour measurement data sent by each scour sensor in the target monitoring area, uses the data processing sub-module 1311 to process each scour measurement data to obtain at least one target scour measurement data, and sends each target scour measurement data to the second monitoring and early warning identification sub-module 131.
[0044] Among them, the scour sensors are pre-buried in the soil layer with severe scour around the offshore wind power foundation in the target monitoring area. The scour sensors at different depths of the soil layer correspond to different scour warning levels, as shown in Figure 2.
[0045] When a scouring disaster occurs, the scouring sensors located at different depths of the soil layer will be washed out by the water flow and transmit the measurement data related to the scouring process to the data acquisition module 11, as shown in FIG3 .
[0046] Among them, the flushing sensor transmits data through an end-to-end wireless transmission sensor signal model. Through this end-to-end wireless transmission sensor signal model, the goal of increasing the distance between feature classes and reducing the distance within classes can be achieved. It can quickly prepare the discriminability of a reliable recognition model, and has a small number of parameters, making it more suitable for deployment on embedded hardware.
[0047] Secondly, after receiving the target scour measurement data, the second monitoring and warning identification submodule 132 inputs the target scour measurement data into the target recurrent neural network model (RNN model) for warning identification, and can obtain the corresponding scour warning level.
[0048] Optionally, the data acquisition module 11 is also used to obtain the wave parameter set and water flow velocity data information set sent by the scour sensor in the target monitoring area when a scour disaster occurs, and determine the evolution relationship between the water flow velocity and wave characteristics in the target monitoring area based on the wave parameter set and water flow velocity data information set. Optionally, a corresponding evolution process diagram can be formed based on the evolution relationship, and synchronous observation of the scour process and water flow characteristics can be achieved based on the evolution process diagram.
[0049] The offshore wind power foundation scour monitoring and early warning identification system provided in the embodiment of the present application obtains a preset scour early warning level data set and a historical scour measurement data set corresponding to the offshore wind power foundation in the data acquisition module; uses feature matching and a preset recurrent neural network algorithm to train the preset scour early warning level data set and the historical scour measurement data set in the data processing and training module to obtain a target recurrent neural network model; when a scour disaster occurs, the target recurrent neural network model can be directly used in the monitoring and early warning identification module to monitor and identify the current scour situation and obtain the scour early warning level. Therefore, by implementing this application, the influence mechanism of the pile body's horizontal cyclic load on pile foundation scour is fully considered, and the scour situation of the offshore wind turbine foundation can be understood more timely, accurately and reliably; different scour levels can be quickly, accurately and reliably identified, and according to the identification results, the losses caused by scour can be effectively prevented, providing technical support for wind turbine operation safety and maintenance.
[0050] In one example, a remote intelligent monitoring and fault warning system for scour on offshore wind turbine foundations is provided. The system includes a scour sensor module for measuring scour depth, wave current, and water velocity; a base station real-time monitoring module for receiving, filtering, and processing scour sensor feedback data; a wireless remote monitoring module for monitoring the hydraulic scour process and issuing warnings, and an intelligent warning recognition model. Schematic diagrams of the specific implementation principle are shown in Figures 4 and 5.
[0051] Specifically, scour sensors are pre-buried in the soil layers around pile foundations, which are prone to scour. When a scour disaster occurs, scour sensors located at different depths in the soil layer are dislodged by the water flow and transmit measurement data related to the scour process. The base station's real-time monitoring module filters and processes this data before transmitting it to the remote monitoring center. After the intelligent warning recognition algorithm identifies the signals transmitted by different sensors, different scour warning levels are generated, as shown in Figure 6.
[0052] In another example, a wind turbine foundation scour monitoring and early warning system is provided. Its hardware includes a Beidou GPS ATGM336H, an E32-TTL-100 wireless serial port, and an STC15F2K single-chip microcomputer. It also includes the SS-DTU68G signal receiver required for the base station's real-time monitoring module. The software is compiled in Python, and the compiled code program displays data such as sensor number, latitude and longitude, date, and water flow velocity. This accurately and concisely displays the required data on the client, achieving real-time monitoring.
[0053] The present embodiment provides a method for monitoring and early warning identification of offshore wind power foundation scour, which is used in the offshore wind power foundation scour monitoring and early warning identification system 1 described in the embodiment of the present application. As shown in FIG7 , the method includes the following steps:
[0054] Step 201: When a scour disaster occurs, at least one scour measurement data is obtained based on each scour sensor in the target monitoring area through an end-to-end wireless transmission sensor signal model.
[0055] Each of the scour sensors is pre-buried in a soil layer with severe scour around the offshore wind power foundation in the target monitoring area.
[0056] The specific implementation process refers to the functional description and definition of the data acquisition module 11 in the offshore wind power foundation scour monitoring and early warning identification system 1 in the above embodiment, which will not be repeated here.
[0057] Step 202: Based on each of the scour measurement data, at least one target scour measurement data is obtained through a preset processing method.

[0059] Step 203: Based on each target scour measurement data, the scour warning level is obtained through target recurrent neural network model identification.
[0060] The target recurrent neural network model is trained using feature matching and a preset recurrent neural network algorithm on a preset scour warning level dataset and a historical scour measurement dataset corresponding to the offshore wind turbine foundation. The specific training process is described in the functional description of the data processing and training module 12 in the offshore wind turbine foundation scour monitoring and warning identification system 1 in the above embodiment and will not be repeated here.
