[0064] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0065] Reference Figure 1 As shown, a dam body detection and control method for a smart hydropower station includes:

[0066] Obtain at least one possible damage type of the dam body, and set a corresponding detection method based on each damage type;

[0067] Based on the historical operation and maintenance management data of the dam, determine all possible dam operation and maintenance events;

[0068] Analyze the correlation between each dam operation and maintenance event and the damage type, and build a damage type risk assessment model;

[0069] Based on the historical operation and maintenance management data of the dam, determine the detection time closest to the current time for each damage type and record it as the initial detection time;

[0070] All dam operation and maintenance events between the initial detection time and the current time are counted and recorded as analysis operation and maintenance events;

[0071] Substitute the analyzed operation and maintenance events into the damage type risk assessment index to obtain the transition assessment index of each damage type;

[0072] Based on the damage type transition evaluation index, the detection accuracy of the detection method corresponding to the damage type is set.

[0073] Based on each detection data and the operation and maintenance events in the adjacent detection intervals, a comprehensive analysis is conducted on the risk indicators of dam damage. The detection accuracy is set based on the risk indicators. The detection accuracy is improved under high risk to ensure a comprehensive detection of the dam body. The detection accuracy is appropriately reduced under low risk, thereby improving detection efficiency and reducing the waste of detection resources.

[0074] Reference Figure 2 As shown in the figure, the correlation between each dam operation and maintenance event and the damage type is analyzed, and the damage type risk assessment model is constructed, which specifically includes:

[0075] Based on each test data in the historical test data, analyze the risk probability of the damage type at each test;

[0076] Calculate the difference between the risk probability of the damage type at the time of detection and the risk probability of the damage type at the previous detection;

[0077] Collect statistics on all dam operation and maintenance events that occurred between the time of the inspection and the time of the previous inspection;

[0078] The difference between the risk probability of the damage type at the time of detection and the risk probability of the damage type at the previous detection and all the dam operation and maintenance events that occurred between the time of detection and the time of the previous detection form a sample data;

[0079] Get all sample data to form a sample data set;

[0080] Based on the sample data set, all dam operation and maintenance events that occurred between the time of detection and the time of the previous detection were taken as input, and the difference between the risk probability of the damage type at the time of detection and the risk probability of the damage type at the time of the previous detection was taken as output. A neural network was used to train a damage type risk assessment model.

[0081] Neural Networks is a computational model that mimics the structure and function of biological neural networks. They are composed of a large number of processing units connected to each other through weighted connections, and can process and learn complex nonlinear relationships and data patterns. In this scheme, based on the neural network model, a large number of operation and maintenance events and the change rate of risk indicators are used as training data to explore the data relationship between the change rate of operation and maintenance events and risk indicators, and then build a damage type risk assessment model.

[0082] Reference Figure 3 As shown in FIG. 1 , the damage type risk assessment model trained by a neural network specifically includes:

[0083] Divide all the data in the sample data set into a training set and a validation set in a ratio of 8:2;

[0084] Construct a loss function, which is a mean square error function;

[0085] Set the regularization coefficient, and introduce the regularization term into the loss function based on the regularization coefficient to obtain the regularized loss function;

[0086] Based on the regularized loss function, several candidate models are trained through the neural network using the training set;

[0087] Use the loss function to evaluate the loss values ​​of several candidate models on the validation set;

[0088] Screen out the candidate model corresponding to the minimum loss value as the training damage type risk assessment model;

[0089] The regularization loss function is specifically:

[0090]

[0091] in, is the regularized loss function, is the loss function, is the regularization coefficient, is the jth parameter of the neural network.

[0092] In the regularized loss value function, the regularization coefficient is added to the loss function as a regularization term. This regularization term is a constraint or penalty on the model parameters, which aims to reduce the complexity of the model. Therefore, the size of the regularization coefficient will directly affect the value of the loss function. When the regularization coefficient is small, the model complexity is relatively high, and overfitting may be more likely to occur. At this time, the loss value may be very low on the training set, but may be high on the validation set or test set. In this scheme, multiple regularization coefficients are pre-set to obtain multiple regularized loss functions. The loss performance of the candidate model trained by each regularized loss function on the validation set is used to screen the best training damage type risk assessment model.

[0093] Reference Figure 4 As shown in FIG. 1 , based on the damage type transition evaluation index, the detection accuracy of the detection method corresponding to the damage type is set to include:

[0094] Based on the detection data corresponding to the initial detection time, the occurrence risk probability of the damage type at the initial detection is analyzed as the basic risk indicator of the damage type;

[0095] The basic risk index of the damage type plus the change assessment index of the damage type are used as the actual risk assessment value corresponding to the damage type;

[0096] Determine several precision adjustment gears corresponding to the detection method corresponding to the damage type;

[0097] Determine the accuracy adjustment gear based on the actual risk assessment value corresponding to the damage type;

[0098] The dam body is inspected by adjusting the gear according to the set accuracy.

[0099] Reference Figure 5 As shown, based on the actual risk assessment value corresponding to the damage type, determining the precision adjustment gear specifically includes:

[0100] Set the actual risk assessment value corresponding to the highest precision adjustment gear, which is recorded as the upper risk assessment threshold;

[0101] Within 0-risk assessment upper threshold, set a number of gradient thresholds corresponding to the number of precision adjustment gears;

[0102] Establish corresponding relationships between all gradient thresholds and precision adjustment gears in order from small to large;

[0103] The actual risk assessment value corresponding to the damage type is compared with the gradient threshold, and the first gradient threshold that is greater than the actual risk assessment value from small to large is determined, and the precision adjustment gear corresponding to the gradient threshold is used as the determined precision adjustment gear.

[0104] It can be understood that the detection system has its upper limit of accuracy and several determined accuracy levels, which are determined by the equipment. In this scheme, a correspondence is established between the upper limit of accuracy and the accuracy level and the risk probability of damage to the dam body. The greater the risk probability of damage to the dam body, the higher the corresponding accuracy level.
