Optionally, the air distribution plate may be a common air distribution plate, or may be a step air distribution plate. In the present embodiment, a step wind distribution plate is taken as an example for description. Before step S11 is executed, the step air distribution plate needs to be assembled to ensure that the aperture ratio of the air distribution plate at the raw coal feeding end is greater than that of the clean coal discharging end, so as to ensure the coal dressing effect and precision.

Fig. 2 is a flowchart of an online detection method for an air distribution plate in another embodiment of the present application, and as shown in fig. 2, the method in this embodiment further includes:

step S15: establishing a target model;

step S16: acquiring historical state information of the air distribution plate and the discharge scraper and hole plugging information of the air distribution plate corresponding to the historical state information;

step S17: and training the target model at least based on the historical state information and the hole blocking information to obtain the detection model.

Specifically, in order to realize the online and real-time detection of the grid plate, the detection process is required to be efficient and accurate, so that the detection model is trained in the embodiment to realize the real-time online detection of the grid plate based on the detection model. When the method is applied, a target model needs to be established first, and the target model can be any model for realizing prediction or any model for realizing classification, including a convolutional neural network model, a binary neural network model, and specifically, a multiple linear regression model and the like. After the target model is determined and the target model architecture is obtained, the obtained historical state information of the air distribution plate and the discharging scraper, namely the historical operation information and/or the structural state information of the air distribution plate and the discharging scraper, and the hole blocking information of the air distribution plate corresponding to the historical state information, namely the information of whether the air distribution plate is blocked or not are preprocessed and then input into the target model to train the target model, for example, the target model is trained and learned from a large amount of preprocessed data through a random forest algorithm, and then the detection model which can predict whether the air distribution plate is blocked or not based on the state information of the air distribution plate and the discharging scraper is obtained.

The preprocessing of the historical state information described in the above embodiment and the preprocessing of the currently obtained state information described in step S12 include the same processing steps, which are both used to obtain the target feature data, and the preprocessing process specifically includes:

and extracting the characteristics of the state information based on characteristic engineering to obtain the target characteristic data, wherein the target characteristic data comprises information which is directly influenced by the hole plugging state of the air distribution plate in the state information.

The characteristic engineering is to carry out a series of engineering processing on the original data, refine the original data into characteristics, and use the characteristics as input for algorithms and models. Essentially, feature engineering is a process of representing and exposing data. In actual work, feature engineering aims to remove impurities and redundancy in raw data, and more efficient features are designed to characterize the relationship between the solved problem and the prediction model. In this embodiment, the obtained state information is preprocessed based on the feature engineering, for example, the state information is subjected to feature normalization processing, so as to obtain information directly affected by the hole blocking state of the air distribution plate in the state information, that is, target feature data, such as motor power of the discharging scraper, motor torque, normal operation, pressure drop of the air distribution plate, pressure applied to the air distribution plate, and the like. The target model is trained based on the acquired historical target feature data as input data and the hole blocking condition of the air distribution plate corresponding to the historical target feature data as output data, and the trained detection model also predicts the hole blocking condition of the current air distribution plate based on the input target feature data.

Further, the state information in this embodiment includes one or more of air tightness information of the air distribution plate, pressure drop information, material thickness stacked on the air distribution plate, motor torque information of the discharging scraper, and information of an acting force of the material on the air distribution plate. For example, take place to block up when the grid plate, lead to the unable normal discharge of material, it receives the material influence of piling up on the grid plate to arrange the material scraper blade, and during unable normal row's material, the material is piled up and can is extrudeed the grid plate, make the grid plate produce abnormal pressure, the effort that the grid plate received can surpass the predetermined range promptly (this pressure value can assist and confirm grid plate stifled hole position and stifled hole area), receive this influence simultaneously, arrange the motor torque of material scraper blade, power all produces unusually, lead to not being in required within range, detection model alright this moment predict whether current grid plate blocks up according to the eigenvalue of above-mentioned characteristic.

Optionally, the hole plugging information in this embodiment includes hole plugging area and hole plugging position information. After the detection model is input with target characteristic data, calculation and prediction are carried out according to the target characteristic data so as to obtain information whether the current air distribution plate is blocked or not, if the current air distribution plate is blocked, the area of the blocked holes is output simultaneously, namely, the number of the blocked holes is the total area, and the positions of the blocked holes are output, so that auxiliary workers can quickly determine and find the air distribution plate which is blocked and the positions on the air distribution plate which are blocked, and timely clean the air distribution plate, thereby ensuring the normal operation of the fluidized bed. Through the method of this embodiment, not only can realize the real-time detection in air distribution plate stifled hole, can effectively promote the detection and the maintenance efficiency in air distribution plate stifled hole moreover, saved manpower and time cost, compare in artifical the detection, the precision is also stronger.

Further, in order to enrich the function of the detection model, so that the detection model not only can detect the blockage condition of the air distribution plate, but also can determine the influence of the fluctuation of the bed pressure of the fluidized bed when the air distribution plate is blocked, fig. 3 is a flowchart of an air distribution plate detection method according to another embodiment of the present application, as shown in fig. 3, in the embodiment, when the detection model is trained, the method further includes:

step S18, obtaining a pressure signal of the pressure applied to the fluidized bed layer corresponding to the historical hole plugging information;

the training the target model based on at least the historical state information and the hole plugging information to obtain the detection model comprises:

and S19, training the target model based on the historical state information, the hole blocking information and the pressure signal to obtain the detection model capable of detecting the hole blocking condition of the air distribution plate and the influence of the hole blocking area on the bed pressure fluctuation.

For example, when the fluidized bed operates in historical time, the pressure applied to the bed can be detected through a pressure sensor arranged on the bed, and specifically, whether the pressure applied to the bed is qualified or not can be detected through receiving a pressure signal and utilizing a time domain and a frequency domain of the pressure signal. The time domain and the frequency domain are basic properties of signals, and the mutual influence between the signals and third-party objects such as interconnection lines can be clearly reflected on the basis of the time domain and the frequency domain. When the air distribution plate is blocked, the pressure applied to the bed layer can fluctuate corresponding to the position and the area of the blocked hole, so that when a user collects training data, pressure signals of the pressure applied to the fluidized bed layer corresponding to historical blocked hole information and relevant attribute information of the pressure signals can be collected simultaneously, the pressure signals are integrated into the training data, namely the training data comprise pressure signal information, historical state information and blocked hole information, and the detection model is trained through the training data, so that the detection model can have the capability of detecting the influence of the blocked hole area on the bed pressure fluctuation.

Further, the method in this embodiment further includes:

determining whether the hole plugging information is consistent with the actual hole plugging condition of the air distribution plate or not, and obtaining a corresponding result;

training the detection model based on the target feature data, the hole plugging information and the corresponding results.

For example, when the hole blocking information output by the detection model is checked by a worker on the spot and the data obtained by the detection of the detection model is consistent with the hole blocking condition of the actual air distribution plate, the data input into the detection model and the data output by the detection model can be added into training data to further train the detection model. And only the data with detection errors, namely the hole blocking information output by the detection model is inconsistent with the hole blocking condition of the actual air distribution plate, at the moment, the input data, the output data and the actual hole blocking data of the current time can be input into the detection model so as to further train the detection model, correct the weight of the detection model and refine the detection precision of the detection model.

Optionally, fig. 4 is a flowchart of a method for detecting a wind distribution plate according to another embodiment of the present application, in order to reduce a detection load of a detection model and achieve faster and targeted detection of blockage of the wind distribution plate, in this embodiment, before performing detection, that is, before preprocessing currently obtained state information to obtain target feature data, as shown in fig. 4, the method further includes:

step S20, determining the air tightness of the air distribution plate and the pressure drop conditions of different areas based on the state information, and simultaneously determining the motor power and the motor torque of the discharging scraper;

and step S21, when one or more of the air tightness, the pressure drop condition of different areas, the motor power and the motor torque is determined to be abnormal, adjusting the air distribution plate and/or the discharging scraper plate based on abnormal data and abnormal positions, and preprocessing the state information to obtain the target characteristic data if the data generated at the abnormal positions after adjustment are still abnormal.

For example, before the air distribution plate is subjected to detection, the air tightness and pressure drop condition of the air distribution plate can be determined based on the obtained state information, and the motor power and the motor torque of the discharging scraper plate are determined at the same time. That is, functional devices such as an air distribution plate of the fluidized bed are adjusted through investigation, if the condition is improved after adjustment, it is indicated that the air distribution plate is not blocked, and if the condition cannot be improved after adjustment, it is determined that the problem is the air distribution plate, and hole blocking detection needs to be performed on the problem. Therefore, the processing load of the detection model can be reduced, the operation of the fluidized bed can be adjusted more quickly, and the normal operation of the whole fluidized bed is ensured.
