BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments; Figure 1 It is a system architecture diagram of the present invention. DETAILED DESCRIPTION

[0010] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0011] Reference Figure 1 , this specific implementation adopts the following technical scheme: a method for river silt treatment, using an intelligent dredging ship, the intelligent dredging ship is equipped with a sensor 1, an intelligent control system 2 and an intelligent sludge treatment system 3, the sensor 1 is used for data collection: in the intelligent identification system, data collection is a crucial link. In order to accurately identify and measure the silt in the river, it is necessary to select appropriate sensors and deploy them in key positions. The main sensors used include cameras, lidars, ultrasonic sensors, conductivity sensors, and water quality analyzers.

[0012] ①. Camera: The camera is the most common data acquisition device, which can capture high-resolution images and video data of the river. By analyzing the color, texture and shape in the image, the location and thickness of the silt can be identified. In addition, computer vision technology can also be used to monitor the environment around the river, such as water color, water level changes, etc.

[0013] ②. Lidar: Lidar is a sensor that measures distance by emitting laser pulses and measuring the time it takes to reflect back. It is able to generate three-dimensional point cloud data of the river channel, which is used to accurately measure the river channel topography and silt thickness. The advantage of Lidar is that it can work in bad weather and night conditions, providing high-precision measurement data.

[0014] ③. Ultrasonic sensors: Ultrasonic sensors measure distance by emitting ultrasonic pulses and receiving the reflected signals. In rivers, they can be used to measure water depth and flow rate, providing important parameters for silt identification and analysis. In addition, ultrasonic sensors can also monitor environmental parameters such as turbidity and temperature of water bodies.

[0015] ④. Conductivity sensor: Conductivity sensor is used to measure the conductivity in water, which can reflect the changes in water quality, such as salinity, organic matter content, etc. By analyzing the changes in conductivity, the distribution and accumulation of river silt can be indirectly determined.

[0016] ⑤. Water quality analyzer: The water quality analyzer can measure the chemical composition of water, such as pH, dissolved oxygen, total phosphorus, etc. These data can help understand the pollution of the river and thus evaluate the impact of silt on water quality.

[0017] The intelligent control system 2 adopts intelligent recognition algorithm model training, including: 1. Image processing and analysis: 1.1 Image preprocessing: Use image processing techniques such as filtering, denoising, contrast enhancement, and grayscale conversion to improve image quality and make the characteristics of silt more obvious.

[0018] 1.2 Image segmentation: The image is segmented into different regions through threshold segmentation, edge detection, region growing and other methods to facilitate subsequent feature extraction and classification.

[0019] 1.3 Feature extraction: Use feature extraction techniques such as color histogram, texture analysis, and shape descriptors to identify visual features related to silt.

[0020] 2. 3D model reconstruction: 2.1 Point cloud processing: The point cloud data generated by the lidar is processed by noise reduction, redundancy removal, ground point filtering, etc. to obtain an accurate three-dimensional model of the river surface.

[0021] 2.2 Surface reconstruction: Through surface reconstruction algorithms (such as surface fitting, volume rendering, etc.), the point cloud data is converted into a continuous three-dimensional surface model.

[0022] 3. Deep Learning and Machine Learning: 3.1 Model training: Use historical silt data and corresponding labels (such as the location and thickness of the silt area) to train deep learning models (such as convolutional neural networks (CNN), recurrent neural networks (RNN), etc.).

[0023] 3.2 Real-time identification: The real-time collected data is input into the trained model, and the model outputs the prediction results of silt, such as location, thickness, etc.

[0024] 4. Data fusion and analysis: 4.1 Multi-source data fusion: Fusion of data from different sensors (such as cameras, lidar, ultrasonic sensors, etc.) to improve the accuracy and completeness of recognition.

[0025] 4.2 Data analysis: Statistical analysis, pattern recognition and other techniques are used to conduct in-depth analysis of the fused data to understand the dynamic changes and influencing factors of silt.

[0026] 5. Decision support and visualization: 5.1 Decision support: Provide identification results to decision makers to help them formulate dredging plans, flood control measures, etc.

[0027] 5.2 Visualization: Visualize the recognition results in the form of graphics, charts, three-dimensional models, etc. to facilitate user understanding and use.

[0028] The specific method of the intelligent dredging boat for river sludge treatment is as follows: 1. Deployment and positioning: Place the smart dredging boat in the river channel that needs to be dredged. Use the GPS positioning system to ensure that the dredging boat is accurately located in the predetermined cleaning area.

[0029] 2. System startup and inspection: Start the power system, hydraulic system and monitoring system of the dredging vessel through the console or remote control. Check whether all sensors and actuators are working properly.

[0030] 3. Automatic detection and dredging: Detection sensors are installed at the bottom of the dredging boat, which can automatically detect the thickness of the silt at the bottom of the river. When silt is detected, the control system will start the hydraulic system and drive the dredging equipment to start working. Dredging equipment usually includes rotating or reciprocating propellers or bulldozers, which can stir and suck up the silt. The sucked up silt is transported to the ship through a conveyor belt or pipeline, or directly discharged to a designated area. The sucked up sludge will contain a lot of water. In order to reduce the water content of the sludge, a centrifugal dehydrator can be loaded in the intelligent dredging boat. Under the action of the centrifugal dehydrator, the water content of the sludge is greatly reduced, the volume of the sludge is reduced, and the subsequent transportation and treatment of the sludge is facilitated.

[0031] 4. Monitoring and adjustment: The operator can observe the working status of the dredging vessel and the river conditions in real time through the monitoring system. The operator can adjust the moving speed, dredging depth and dredging range of the dredging vessel as needed.

[0032] 5. Data recording and analysis: The dredging vessel will record the distance, volume and other information of the dredging during the work. The operator can analyze the data after the work is completed to evaluate the dredging effect and provide reference for future dredging plans.

[0033] 6. Stop work and equipment recovery: When the dredging vessel completes the scheduled dredging task or reaches the work limit, the operator can remotely stop the dredging work. Use boats or lifting equipment to recover the dredging vessel from the river channel and carry out necessary maintenance and inspection.

[0034] This specific implementation adopts an intelligent dredging ship, which is loaded with sensors, intelligent control systems and intelligent dredging systems. After the sensors collect various data on river sludge, the intelligent control system intelligently integrates the sludge data through the intelligent training module, and finally issues instructions to control the intelligent dredging system to accurately process the sludge, thus realizing the full intelligentization of river sludge management.
