Description

Technical Field

[0001] This invention relates to the field of screening and monitoring technology, and in particular to an intelligent online screening and monitoring method and system for ores. Background Technology

[0002] Ore screening monitoring refers to the process of real-time collection, analysis, and evaluation of the ore's status during screening, grading, and conveying stages through cameras or online detection devices placed around the screening equipment during ore processing and beneficiation. Combined with deep learning models, it identifies risk characteristics in the ore screening process, including: ore accumulating at the screen edge (approaching clogging), ore containing a large amount of clay (easily sticking to the screen), or the presence of other ores or debris in the ore.

[0003] However, during the transformation towards digitalization and intelligent screening in the mining industry, due to the unique characteristics of ore materials, the ore images, particle characteristics, and operational status data collected from a single mine are far from covering all possible ore types, particle size distributions, and impurities. When training deep learning models, the lack of training samples easily leads to insufficient generalization ability, especially for some small mines. Furthermore, small mines typically have limited computing resources and lack high-performance computing clusters, further increasing the difficulty of training complex neural networks. This prevents the neural networks from undergoing multiple rounds of iterative optimization, significantly limiting the accuracy of model recognition.

[0004] Therefore, "how to address the problem of limited deep learning model training caused by limited sample size and computing resources in small mining farms" is the technical problem that this invention aims to solve. Summary of the Invention

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] In Example 1, Figure 1 The implementation flow of the intelligent online ore screening and monitoring method provided in this embodiment of the invention is illustrated below, and is described in detail below:

[0056] S100: Locate the screening equipment in the ore screening and processing area, create an image recognition model, use video monitoring equipment pre-deployed in the screening equipment to collect ore images during the screening process, create a labeled image set, train the image recognition model, and extract model parameters from the trained image recognition model.

[0057] The area for ore screening is designated, which could be a mine or a processing area. Screening equipment, such as vibrating screens or fixed screens, is located through on-site surveys or equipment inventory. A deep learning network architecture (such as a convolutional neural network) suitable for industrial vision scenarios is selected to create an image recognition model. Keyframes of the screening process are captured using video monitoring equipment, and preprocessing operations such as noise reduction, cropping, and viewpoint correction are performed. Then, ore processing managers annotate the keyframes, marking abnormal features in the images. These abnormal features include: ore... Stones accumulate at the edge of the screen (approaching blockage), the ore contains a large amount of clay (easily sticking to the screen), or other ores and miscellaneous stones are present in the ore. A labeled image set is constructed using the labeled keyframes; in other words, the labeled image set is a collection of labeled keyframes. The image recognition model is trained using this labeled image set, enabling it to identify the visual features of the ore under different screening conditions and the operating status of the equipment. Model parameters are extracted from the trained image recognition model, including: convolutional kernel weights, feature extraction layer parameters, fully connected layer weights, and classification thresholds.

[0058] S200: Create an online monitoring platform for ore screening, identify registered users, configure the identity attributes of each registered user, wherein the identity attributes include at least: sharer and subscriber, receive model parameters uploaded by sharers, collect hardware information of screening equipment of each registered user, and cluster registered users into several groups, wherein there is at least one sharer in each group.

[0059] An online monitoring platform is created, primarily for the collection, sharing, and management of model parameters. Users who register with their real identities are defined as registered users. It's important to note that "users" here refers to mining farms. The platform receives registration information uploaded by registered users and, based on their willingness and business capabilities in the ore screening industry, classifies them into sharers and subscribers. Sharers are registered users who voluntarily share the model parameters of their mining farm, while subscribers are registered users who, due to limitations in their own data and computing resources, are unable to train neural networks. Sharers upload the trained and optimized model parameters to the online monitoring platform, making them available to subscribers. This enables the sharing and reuse of model parameters, providing other mining farms with a foundation for directly deployable or further optimized image recognition models. The system receives and stores model parameters uploaded to the online monitoring platform by sharers; it collects hardware information from each registered user, including equipment model, screen specifications, and screen vibration frequency. Based on the similarity of hardware information, registered users are categorized into several groups, with at least one sharer in each group. The model parameters uploaded by this sharer can be accessed by subscribers within the same group. The advantage of this method is that by sharing model parameters from sharers within the same group, the adaptability of model parameters can be further improved, while simultaneously increasing the recognition accuracy of the image recognition model.

[0060] S300: The model parameters of the sharer are distributed in parallel to all subscribers in the same group via the online monitoring platform, and the model parameters are deployed to the image recognition model pre-built by the subscriber to obtain several control models.

[0061] Using an online monitoring platform, the model parameters of the sharer are simultaneously distributed to all subscribers within the same group. Subscribers then deploy the received model parameters into their pre-built image recognition models and perform recognition and analysis on the image data collected by the video surveillance equipment. In actual deployment, when there is only one sharer in the group, each subscriber receives one set of model parameters. Similarly, when there are multiple sharers in the group, each subscriber receives multiple sets of model parameters. Using the same image recognition model architecture and multiple sets of model parameters, multiple control models are generated. It can be seen that each control model carries model parameters from different sources.

[0062] S400: Obtain the labeled image set of the subscriber, train the control model, construct a test image set, input it into the control model, and set the confidence score of each control model according to the output results. Define the control model with the highest confidence score as the target model, where each subscriber corresponds to a target model. Locate the edge equipment in the ore screening and processing area of ​​the subscriber, deploy the target model to the edge equipment, and perform online monitoring of the screening equipment.

[0063] By utilizing video surveillance equipment deployed in subscribers, image data of the screening equipment during processing is collected. Annotated image sets are generated for each subscriber through manual labeling. These sets are used to train a control model, and the model parameters are fine-tuned to adapt to the specific screening environment and ore characteristics of the subscriber's mine. After training, an independent test image set is constructed, still composed of image data from the subscriber's screening equipment. This test image set is input into each control model to obtain output results. Ore processing managers score the control models based on the output results and set corresponding confidence scores. The control model with the highest confidence score is defined as the target model. It can be seen that the number of control models may be one or more, the specific number is not limited, but the number of control models is limited to one.

[0064] Identify edge devices located in the subscriber's ore screening and processing area. These edge devices can be edge computing boxes, smart gateways, etc. Deploy the target model into the edge devices. In the screening equipment, a smart camera with data processing capabilities can be selected, and the target model can be deployed in the smart camera. Using the target model, the image data of the screening equipment collected in real time is processed, thereby enabling online monitoring of the operating status of the screening equipment and the ore screening process.

[0065] In Embodiment 2, unlike Embodiment 1, the method further includes:

[0066] The video surveillance equipment collects image data from the subscriber screening device and inputs it into the target model, outputting several image features. These image features are then clustered into a regular group, an uncertain group, and a risk group.

[0067] From the image data, a snapshot containing uncertain groups is extracted, and the snapshot is sent to the image recognition model of the sharer in the same group to output the evaluation result;

[0068] Based on the evaluation results, the image features of the uncertain group are classified into the normal group or the risk group.

[0069] Video monitoring equipment deployed on subscriber screening devices collects image data in real time during the ore screening process. This image data is then input into a pre-deployed target model. The target model uses a pre-trained feature extraction network to identify and generate several image feature vectors. These feature vectors reflect the ore's packing state, particle size distribution, mud content, impurities, and screen blockage. The feature vectors are compared with a pre-built vector set, and the corresponding image data is categorized into normal, uncertain, and risk groups. The pre-built vector set consists of multiple feature vectors and corresponding risk assessments. The normal group includes image features indicating normal screening and ore characteristics that meet expectations. The uncertain group includes image features with blurred features or other risks that cannot be clearly determined. The uncertain group may be caused by dust obscuring the image data, affecting its accuracy, or by model distortion. The risk group corresponds to image features with obvious abnormalities or risk characteristics, such as screen blockage, severe ore packing, or excessively high impurity ratios.

[0070] From the image data corresponding to the uncertain group, potentially risky features are extracted to obtain a snapshot. This snapshot is then sent to the image recognition model of the sharing user to obtain an evaluation result. Based on this evaluation result, the image features of the uncertain group are classified into the normal group or the risk group. In this application, by sharing model parameters, the image recognition model can be rapidly deployed without relying on a large amount of its own data for independent training. Furthermore, since the image data cannot be transmitted externally, the risk of production data leakage is greatly reduced. By only sending snapshots to the image recognition models of other registered users, the status of the screening equipment can be quickly determined while protecting data privacy.

[0071] In Embodiment 3, unlike Embodiment 1, the method further includes:

[0072] Create emergency response rules and establish the correspondence between each risk characteristic in the risk group and the emergency response rules;

[0073] The emergency response rules are written into the edge device, and control permissions for the screening device are granted to the edge device.

[0074] Set corresponding emergency response rules for each risk characteristic, and write all risk characteristics into the edge device. At the same time, grant control permissions to the screening equipment to the edge device so that the edge device can quickly adjust the screening equipment according to the emergency response rules when a risk characteristic is detected.

[0075] In Example 4, Figure 2The implementation flow of the intelligent online screening and monitoring method for ores provided in this embodiment of the invention is illustrated below. The steps of creating a labeled image set, training the image recognition model, and extracting model parameters from the trained image recognition model are described in detail below:

[0076] S101: Integrate the sharers and subscribers corresponding to the same set of model parameters and define them as node groups. Based on the node groups, build a federated learning architecture.

[0077] S102: The model parameters of the subscribers are dynamically updated via the federated learning architecture.

[0078] By integrating sharers and subscribers using the same set of model parameters to form node groups, a federated learning architecture is constructed. This allows each node group to perform distributed training and iterative optimization of the image recognition model through the sharing and aggregation of model parameters, without sharing the original image data from the screening equipment. The advantage of this approach is that it can maintain the updating and iteration of the image recognition model even when the subscriber's data sample size is small.

[0079] In Example 5, Figure 3 The implementation flow of the intelligent online ore screening and monitoring method provided by an embodiment of the present invention is illustrated below. The steps of creating an online monitoring platform for ore screening, identifying registered users, and configuring the identity attributes of each registered user are described in detail below:

[0080] S201: Receive the set of labeled images uploaded by registered users to the online monitoring platform, trace back the data source, and collect the feature information of the data source, wherein the feature information includes at least: ore type and particle size.

[0081] A community interaction module is built in the online monitoring platform, allowing registered users to share labeled image sets. It should be noted that the labeled image sets are shared voluntarily and are historical data, so there is no risk of data leakage. The data source of each labeled image set is determined, which is the registered user who uploaded and shared the labeled image set. The characteristic information of the data source is determined, including ore type and particle size.

[0082] S202: Based on the feature information, merge the labeled image set.

[0083] By merging labeled image sets with the same or similar features, the generalization ability of the target model can be enhanced while broadening the data sources.

[0084] In Example 6, Figure 4The implementation flow of the intelligent online ore screening and monitoring method provided by an embodiment of the present invention is illustrated. The following details the step of distributing the model parameters of the sharer to all subscribers in the same group in parallel via the online monitoring platform:

[0085] S301: Record the changes in model parameters, generate a version, and upload it to the online monitoring platform for storage.

[0086] After the target model is updated and iterated, the process of changing the model parameters is recorded, including the parameter modification time, modification content, mine and operator information, etc. The process of changing the parameters is recorded in the form of versions, and the resulting versions are uploaded to the online monitoring platform for storage.

[0087] S302: Embed a timestamp into the version, arrange them in chronological order, generate a version chain, and integrate a rollback mechanism.

[0088] Embed timestamps into the versions and integrate all versions in chronological order to generate a version chain. Integrate a rollback mechanism into the version chain. The rollback mechanism means that when the recognition accuracy of the target model decreases, an anomaly is detected, or a deployment failure occurs, it can roll back to any version and re-call the model parameters in that version.

[0089] In Example 7, Figure 5 The implementation flow of the intelligent online ore screening and monitoring method provided by an embodiment of the present invention is illustrated. The following details the steps of locating the edge devices in the subscriber's ore screening and processing area, deploying the target model to the edge devices, and performing online monitoring of the screening devices:

[0090] S401: Adjust the confidence score according to a preset frequency.

[0091] The confidence score is updated at a preset frequency, which can be once a day or once a week.

[0092] S402: Establish a mapping between screening equipment and edge equipment, build a communication link, and generate an online monitoring network.

[0093] Based on the deployment location and usage of screening equipment and edge devices, an association is established between the screening equipment and edge devices, with each screening equipment corresponding to at least one edge device. A communication link is also established to integrate all screening equipment and edge devices and build an online monitoring network. The advantage of this approach is that it enables data sharing and collaborative work between different screening equipment and edge nodes.
