Description

Technical Field

[0002] Ditching plays a vital role in rapeseed cultivation, especially in the tillage and sowing stages. Reasonable ditching depth, width and ditch bottom flatness directly affect the growth environment, germination rate and later irrigation effect of rapeseed. Therefore, monitoring the quality of ditching becomes particularly important. Ditching of rapeseed is an important part of agricultural production. Especially in the context of the popularization of mechanized tillage, how to improve the quality and efficiency of ditching has become one of the key issues in the development of modern agriculture. Especially in the process of mechanized operation, manual control is difficult and the quality fluctuates greatly, so it is necessary to rely on intelligent technology for quality monitoring and optimization. The quality of ditching is directly related to the looseness of the soil, sowing depth, drainage in the ditch and the later irrigation effect. Therefore, monitoring the quality of ditching has become an important part of the intelligent agricultural management system. However, the traditional ditching quality monitoring method mainly relies on manual measurement and visual evaluation, supplemented by simple measurement tools and empirical analysis, and is judged by checking the length, width, slope and collapse or obvious defects of the ditch wall.

[0003] Insufficient existing technology:

[0004] Traditional ditching quality monitoring has problems such as low efficiency, insufficient accuracy, lack of real-time and dynamic environmental considerations. Traditional methods rely on manual visual inspection and simple tools, which are highly subjective and have low accuracy. They cannot comprehensively evaluate the linkage effects of multi-dimensional features such as width, depth and angle, and ignore the dynamic effects of environmental factors such as temperature, humidity and soil permeability on ditch quality.

[0005] In large-scale rapeseed planting or other agricultural projects, the quality monitoring of a large number of ditches will lag behind due to the low efficiency and poor accuracy of traditional methods, affecting the overall agricultural planning and production efficiency. In addition, traditional evaluation methods are not flexible enough and difficult to adapt to different operating environments and ditch types.

[0060] Example:

[0061] See also Figure 1 , a method for monitoring the quality of trenching operations based on rapeseed planting, the specific steps include:

[0062] Step 1: Collect relevant characteristic data of the ditch after the trenching machine operates, wherein the relevant characteristic data includes ditch width, ditch depth, ditch length and ditch opening angle;

[0063] Step 2: After preprocessing the relevant characteristic data of the ditch, the deviations of the ditch width, ditch depth and ditch opening angle from their corresponding standard values ​​are calculated respectively, and a characteristic vector of the ditch is generated according to the deviations between the characteristic data and the standard values. The preprocessing includes characteristic data cleaning and data standardization processing;

[0064] Step 3: Construct a quality evaluation model using a convolutional neural network structure, including an input layer, a hidden layer, and an output layer. The input layer receives feature vectors, the hidden layer is responsible for data processing of feature vectors, and the output layer is used to output the ditch quality index. The feature vectors are input into the quality evaluation model to obtain the ditch quality index.

[0065] Step 4: Collect the optimal temperature and humidity of the ditch after the ditching operation, the current temperature and humidity, and the soil permeability of the ditch, and calculate the quality evaluation index of the ditch by combining the temperature deviation value and the humidity deviation value;

[0066] Step 5: Use the generated ditch quality evaluation index to correct the evaluation threshold to obtain the evaluation threshold correction value, compare the quality index with the evaluation threshold correction value, and determine whether the ditch meets the ditching quality standard.

[0067] It should be noted that by standardizing the feature data of different dimensions to the same scale range, the impact of feature value range differences on model weight learning is reduced, the convergence process of the model is accelerated, and the performance and prediction ability of the model are significantly improved. This preprocessing provides the model with cleaner and more uniform data input, laying the foundation for efficient model learning.

[0068] Therefore, it is necessary to pre-process the relevant characteristic data of the ditch including the ditch width, ditch depth, ditch length and ditch opening angle. The pre-processing includes characteristic data cleaning and data standardization. The method is as follows:

[0069] Data cleaning of feature data includes detection and deletion of outliers and duplicate data, and processing of missing values. Specifically, it uses statistical methods to identify outliers and duplicate data in feature data, deletes outliers and duplicate data in feature data, and uses the mean, median or mode of feature data to fill in missing values ​​in feature data.

[0070] The feature data is normalized as minimum-maximum normalization, scaling the data to Within the range, all feature data have the same scale, based on the formula:

[0071] ;

[0072] in, is the feature data after normalization. is the original feature data, is the minimum value of the same type of feature data in the data set. It is the maximum value of the same type of feature data in the dataset.

[0073] It should be noted that by quantifying the difference between the actual value and the standard value, an objective basis is provided for evaluating the quality of ditch construction. The setting of the deviation value is based on the standard value in the historical ditching data, which can reflect the degree of consistency between the actual ditch construction and the ideal design, and help to timely discover problems in construction and propose improvement plans. By clarifying the deviation value, the accuracy and consistency of ditch construction can be improved, thereby better meeting the needs of farmland drainage and flood control, and improving agricultural production efficiency and land resource utilization.

[0074] Therefore, it is necessary to calculate the deviations of ditch width, ditch depth, ditch length and ditch opening angle from their respective standard values, based on the following method:

[0075] The standard values ​​of ditch width, ditch depth and ditch opening angle after ditching are obtained from the historical ditching data, and the deviation values ​​of each parameter are calculated based on the following formula:

[0076] ;

[0077] ;

[0078] ;

[0079] ;

[0080] in, , , , Respectively represent the deviation values ​​of ditch width, depth, length and opening angle, , , , The collected ditch width, depth, length and opening angle data are respectively: , , , They are the standard values ​​of ditch width, depth, length and opening angle respectively.

[0081] It should be noted that by generating a feature vector from the deviation values ​​of ditch width, depth, length and opening angle and inputting it into the neural network model, quantitative evaluation and prediction of ditch quality can be achieved. The introduction of the model can not only improve the efficiency and accuracy of quality evaluation, but also replace the traditional subjective judgment that relies on manual experience, ensuring the objectivity and consistency of the evaluation results. At the same time, through the annotation training of historical data, the model can gradually optimize the ability to identify ditch construction problems and provide scientific guidance for future construction.

[0082] Therefore, it is necessary to construct a quality evaluation model based on the following methods:

[0083] The quality evaluation model adopts a neural network convolution structure, including an input layer, a hidden layer and an output layer. The input layer is used to receive the feature vector of the ditch, the hidden layer is used to process the feature vector of the ditch, and the output layer is used to output the predicted ditch quality index. , the larger the quality index, the better, which means that the quality standard of the ditch after the ditching operation is high and has more condition parameters for growing rapeseed;

[0084] The feature vectors of ditches formed by previous ditching operations are obtained, and the ditches are scored based on experts to obtain the ditch quality index. The feature vectors of ditches formed by historical ditching operations are used as input, and the ditch quality index is used as a label to train the quality evaluation model. During the training process, the mean square error function is selected as the loss function, and the loss function value is calculated based on the output result and the true label. The gradient is calculated through the back propagation algorithm, and the weights and bias of the neural network are updated. The above operation is repeated until the model reaches the predetermined number of training rounds.

[0085] It should be noted that by using temperature and humidity sensors to collect current temperature and humidity, and combining the best temperature and humidity conditions in historical data, the deviation value is calculated to achieve quantitative evaluation of ditch quality, and the construction quality and environmental adaptability of the ditch can be intuitively reflected by calculating quality evaluation indicators. After the construction is completed, it can be quickly determined whether the ditch has reached the best use conditions, providing a scientific basis for timely repair.

[0086] Therefore, it is necessary to calculate the quality evaluation index of the ditch, based on the following method:

[0087] Obtain the optimal temperature and humidity of the ditch after the ditching operation, and measure the current temperature and humidity by arranging the temperature and humidity sensors arranged on the ditch, and calculate the deviation between the current temperature, current humidity and the optimal temperature and humidity;

[0088] Calculation of ditch soil permeability using double ring infiltration method ;

[0089] The formula for calculating the quality evaluation index of the ditch is:

[0090] ;

[0091] in, It represents the quality evaluation index of the ditch. , is the current temperature and the current humidity, , To achieve the best temperature and humidity of the ditch after trenching. is the deviation between the current temperature and the optimal temperature, is the deviation between the current humidity and the optimal humidity, is the ditch soil permeability; in the above formula, the ditch soil permeability The larger the ditch quality evaluation index is, the The smaller it is, the more effectively the ditch can drain and infiltrate water, improving its overall operating efficiency; The larger the value is, the greater the deviation between the current temperature and the optimal temperature will be, which will lead to Increase, Increase means that the temperature of the ditch is too low, causing the soil to freeze, or the temperature is too high, causing the soil to dry and harden, which leads to a decrease in permeability and a decrease in quality evaluation indicators. Increase, the operation status and quality of the ditch are not ideal, on the contrary The smaller the value of The smaller it is, the better the running status and quality of the ditch are. The larger the value, The larger the value, the greater the deviation between the current humidity and the optimal humidity, which means that the humidity of the ditch is too low and the soil is cracked, or the humidity is too high and the soil is waterlogged, thus affecting the stability of the ditch. The index based on temperature reflects the quality evaluation index The reason for the large impact is that the impact of temperature change far exceeds that of humidity, and the impact of temperature is often nonlinear and changes dramatically with the deviation, which conforms to the characteristics of an exponential function.

[0092] It should be noted that by dynamically adjusting the threshold in combination with the quality index, the quality standard in the actual environment can be effectively reflected. Finally, by judging whether the ditch quality index reaches the correction threshold, it is clear whether the ditch meets the ditching quality standard. This method ensures the scientificity, accuracy and applicability of the evaluation process, provides a reliable basis for ditch construction and management, and helps to ensure project quality and operational safety.

[0093] Therefore, it is necessary to use the generated ditch quality evaluation index to correct the evaluation threshold to obtain the evaluation threshold correction value, and compare the quality index with the evaluation threshold correction value. The formula is as follows:

[0094] ;

[0095] in, represents the evaluation threshold correction value, is the evaluation threshold; in the above formula, the reason why The correction is made because the quality evaluation index The smaller the value, the better the ditch quality. No higher evaluation threshold is needed to evaluate the ditch quality index. The larger it is, the poorer the ditch quality is, and a higher evaluation threshold is needed to assess the ditch quality index;

[0096] According to the obtained evaluation threshold correction value, the size of the ditch quality index and the evaluation threshold correction value is judged based on the following logic:

[0097] ;

[0098] in, The logical value indicating the size of the ditch quality index and the evaluation threshold correction value. When , it indicates that the ditch quality index is less than the evaluation threshold correction value and does not meet the ditching quality standard; when , indicating that the ditch quality index is not less than the evaluation threshold correction value, and meets the ditching quality standard. is the ditch quality index.
