[0024] The accompanying drawings are used to provide a further understanding of the embodiments of the present invention and constitute a part of the specification. Together with the following specific implementations, they are used to explain the embodiments of the present invention, but do not constitute a limitation on the embodiments of the present invention. In the accompanying drawings: Figure 1 It is a schematic flow diagram of the automatic circulation method of the SCR denitration catalyst provided by an embodiment of the present invention; Figure 2 It is a schematic structural diagram of an SCR denitration catalyst automatic circulation device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0025] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0028] Embodiment 1 Please refer to Figure 1 , Figure 1 : is a schematic flow chart of an automatic circulation method of an SCR denitration catalyst provided by an embodiment of the present invention, the method comprising the following steps: S100, obtaining voice information related to the SCR denitration catalyst sent by the user; SCR denitration catalyst related voice information refers to a piece of voice information containing relevant information of SCR denitration catalyst, including but not limited to: type, name, number and circulation status of SCR denitration catalyst, etc. For example: the honeycomb SCR denitration catalyst numbered 0001 is stored.

[0029] It should be noted that the flow state refers to whether a storage operation or an extraction operation is performed on the SCR denitration catalyst in the voice information.

[0030] In one embodiment, before step S100, the process includes: S110, collecting the user's login username, login password, fingerprint features, facial features and iris features, and obtaining the current time; A login username is an identifier used by a user when logging into a system or application. It is a unique name set by a user when registering or creating an account, and is usually used to identify the user so that the system can verify the user's credentials and grant the appropriate permissions. A login username can be any combination of characters chosen by the user, usually the user's name, email address, or other personal identifier.

[0031] A login password is a password used to log into an account. It is a key for an individual to enter a website or application and is used to verify the user's identity and gain access.

[0032] Fingerprint features refer to the important basis for fingerprint recognition. Fingerprints are the uneven lines on the surface of the fingertips of human fingers, which form a unique ridge pattern. Fingerprint features are usually divided into three levels: the first-level features (global features) mainly include singular points (such as center points and triangle points) and type features; the second-level features are mainly fingerprint detail points, such as bifurcation points and terminal points; the third-level features include the dimensional attributes of the ridges.

[0033] Facial features include the feature information of specific parts and the overall feature information. In facial expression recognition, the features of specific parts such as eyes and mouth, as well as the overall features of the face, such as facial structure, face shape and gender, all have an important impact on the recognition of facial expressions. The representation of facial features can be divided into three categories: representing facial features with points (such as boundary points or feature points), defining facial features with lines or boundaries, and defining facial features with regions.

[0034] Iris characteristics refer to the structural and color characteristics of the iris of the eye. The iris is composed of fine fiber tissues, and the organization and weaving pattern of these fibers constitute the structural characteristics of the iris. The structure of the iris can be understood from four aspects: the density and depth of the fibers, and the relative position and size of the iris and its pupil.

[0035] In one embodiment, a fingerprint image is converted into a digital signal through a special fingerprint collection device (such as an optical fingerprint sensor or a capacitive fingerprint sensor), and then the collected fingerprint image is preprocessed (such as denoising, enhancement, thinning, etc.), and then representative feature points are extracted from the preprocessed image, such as the end points and bifurcation points of the fingerprint lines, etc. These feature points are used to form a fingerprint feature template. Finally, the extracted feature template is compared with the template in the database to identify the individual identity.

[0036] In one embodiment, a camera or a professional facial scanning device is used, and then the collected facial image is pre-processed through image processing technology, such as adjusting the light, removing noise, etc., and then the system will identify the main feature points of the face, such as the position and shape of the eyes, nose, and mouth.

[0037] In one embodiment, a dedicated iris scanner is used. The device emits light into the eye and captures a detailed image of the iris. After the iris image is pre-processed, the system extracts feature points of the iris, such as texture, spots, etc.

[0038] S120, if the user's login username corresponds to the user's login password, the current time is within the preset time period, and the user's facial features match the preset user's facial features, then obtaining the SCR denitration catalyst related voice information sent by the user; In one embodiment, the preset time period refers to 8:00 AM-19:00 PM, which is not specifically limited in the embodiment of the present invention and can be reasonably set according to actual needs.

[0039] The correspondence between the user's login username and the user's login password means that the login username and password entered by the user can log in to the system.

[0040] Specifically, if the user's login username is exactly the same as the user's login password, the current time is within the preset time period, and the user's facial features match the preset user's facial features, then the system will be able to successfully verify the user's identity. In this case, the system will allow the user to proceed to the next step, that is, to obtain the voice information sent by the user related to the SCR denitration catalyst.

[0041] S130, if the user's login username corresponds to the user's login password, and the user's fingerprint feature and iris feature match the preset user's fingerprint feature and iris feature respectively, then obtain the SCR denitration catalyst related voice information sent by the user.

[0042] Specifically, if the user's login username is exactly the same as the user's login password, and the user's fingerprint and iris features are exactly the same as the fingerprint and iris features of the user pre-set in the system, then the system will be able to successfully verify the user's identity. In this case, the system will allow the user to proceed to the next step, that is, to obtain the voice information sent by the user related to the SCR denitration catalyst.

[0043] In this embodiment, by combining the traditional username and password with advanced biometrics technology, the system achieves enhanced identity authentication security, effectively prevents unauthorized access, and has environmental adaptability, automatically adjusting the authentication method according to the time period to meet user needs. At the same time, the system improves the quality of data collection by ensuring that voice information is collected under the correct conditions, providing a reliable basis for data analysis.

[0044] S200, converting the voice information related to the SCR denitration catalyst into text to obtain text information of the SCR denitration catalyst; In one embodiment, step S200 specifically includes: S210, extracting features of voice information related to the SCR denitration catalyst to obtain a plurality of voice feature information; The speech feature information includes, but is not limited to, Mel-frequency cepstral coefficients, linear prediction coefficients, fundamental frequency, formant, and short-time energy.

[0045] Mel-frequency cepstral coefficient: reflects the spectral characteristics of speech.

[0046] Linear prediction coefficient: used to estimate the short-time power spectrum of the speech signal.

[0047] Fundamental frequency: reflects the vibration frequency of the vocal cords.

[0048] Resonance peak: reflects the resonance characteristics of the vocal tract.

[0049] Short-time energy: reflects the intensity information of speech.

[0050] S220, inputting multiple voice feature information into a preset voiceprint recognition model to obtain an optimal path corresponding to each voice feature information; wherein the preset voiceprint recognition model is obtained by training a hidden Markov model; Specifically, the extracted speech feature information is input into the trained HMM model, and then decoded using the Viterbi Algorithm to find the best path corresponding to each speech feature sequence, that is, the state sequence that is most likely to produce the speech sequence.

[0051] S230, obtaining text information of the SCR denitration catalyst according to the optimal path corresponding to each voice feature information.

[0052] Specifically, according to the optimal path, the state sequence is mapped back to the corresponding text information, thereby obtaining the relevant text information of the SCR denitration catalyst.

[0053] S300, performing entity naming recognition on text information of the SCR denitration catalyst to obtain a named entity of the SCR denitration catalyst; wherein the named entity includes: type, name, and circulation status; In one embodiment, step S300 specifically includes: S310, obtaining text information of the SCR denitration catalyst; S320, inputting the text information of the SCR denitration catalyst into the word vector mask layer to obtain the word vector of the text information of the SCR denitration catalyst; It is understandable that the BERTwwm model is used for word embedding. BERTwwm is an improved version of BERT, which uses a whole word masking strategy to better handle languages ​​with complex word order structures such as Chinese. In the word embedding stage, each input geological entity is converted into a high-dimensional vector that contains rich semantic information about the entity. The purpose of this step is to convert the SCR denitrification catalyst entity from its original text form into a numerical form that can be processed by the machine learning model.

[0054] It is understandable that the BERTwwm model needs to perform word segmentation on the text information of the SCR deNOx catalyst before converting the text information of the SCR deNOx catalyst into word vectors.

[0055] In one implementation, the word segmentation process uses a word segmentation algorithm suitable for the field of geology, such as rule-based word segmentation or statistical-based word segmentation.

[0056] In addition, a word segmentation dictionary is constructed based on the professional vocabulary and terminology in the field of geology to improve the accuracy of word segmentation. For new words or terms, they are searched and supplemented through online dictionaries or professional knowledge bases.

[0057] S330, inputting the word vector of the text information of the SCR denitration catalyst into the word vector embedding layer to obtain the sequence features of the text information of the SCR denitration catalyst; Understandably, a bidirectional long short-term memory network (BiLSTM) is used for sequence encoding. BiLSTM is an advanced recurrent neural network that processes the input sequence in two directions (i.e., forward and backward), so it can capture the contextual information of the geological entity. In the sequence encoding stage, the model encodes the sequence of the input text information of the SCR denitrification catalyst to generate a new vector sequence that contains the contextual information of each entity. The purpose of this step is to extract the contextual features of the SCR denitrification catalyst entity to enhance the semantic understanding ability of the model.

[0058] S340, inputting the sequence features of the text information of the SCR denitration catalyst into the word vector decoding layer to obtain the named entity of the SCR denitration catalyst.

[0059] It is understandable that conditional random fields (CRF) are used for feature extraction. CRF is a powerful sequence model that can consider the information of the entire sequence for prediction. In the feature extraction stage, CRF processes the output of BiLSTM to extract useful features. The purpose of this step is to extract the most useful features for SCR deNOx catalyst entity identification from the context features. After feature extraction, this patent uses CRF for sequence decoding. In the sequence decoding stage, CRF labels each SCR deNOx catalyst entity based on the extracted features and generates a label sequence. This label sequence represents the category of each SCR deNOx catalyst entity, such as strata, minerals, fossils, etc. The purpose of this step is to predict the category of each SCR deNOx catalyst entity based on the extracted features.

[0060] S400, determining the storage location management information of the SCR denitration catalyst based on the type, name and circulation state of the SCR denitration catalyst, and generating a circulation instruction of the SCR denitration catalyst based on the storage location management information of the SCR denitration catalyst; In one embodiment, step S400 specifically includes: S410, if the circulation state of the SCR denitration catalyst is the storage state, determining the storage condition of the SCR denitration catalyst based on the type and name of the SCR denitration catalyst, and determining the bin position that meets the storage condition of the SCR denitration catalyst as the bin storage position of the SCR denitration catalyst; and generating a storage instruction of the SCR denitration catalyst based on the bin storage position of the SCR denitration catalyst; Storage conditions include but are not limited to: temperature, humidity, light and other factors.

[0061] Specifically, if the circulation state of the SCR denitration catalyst is a storage state, it is necessary to determine its storage conditions in detail according to the specific type and name of the SCR denitration catalyst to ensure that the SCR denitration catalyst remains in the best state during storage. After the storage conditions are determined, a bin location that meets the storage conditions of the SCR denitration catalyst is further selected based on these conditions, and it is determined as the bin storage location of the SCR denitration catalyst. In addition, based on the bin storage location of the SCR denitration catalyst, a corresponding storage instruction of the SCR denitration catalyst is generated to ensure that it can be managed according to the established conditions during storage, and the SCR denitration catalyst is stored in the bin storage location of the SCR denitration catalyst.

[0062] S420, if the circulation state of the SCR denitration catalyst is the extraction state, then based on the type and name of the SCR denitration catalyst, the inventory of the SCR denitration catalyst is queried, and when the inventory of the SCR denitration catalyst is greater than the preset inventory, the bin position of any SCR denitration catalyst is determined as the bin extraction position of the SCR denitration catalyst; and based on the SCR denitration catalyst bin extraction position, an extraction instruction for the SCR denitration catalyst is generated.

[0063] It is understandable that setting the inventory greater than the preset inventory is to ensure that a certain amount of catalyst is always kept in the warehouse. This helps prevent the depletion of the type of SCR denitration catalyst in the warehouse due to over-extraction, thereby avoiding out-of-stock situations during the production process.

[0064] Specifically, if the circulation state of the SCR denitration catalyst is the extraction state, it is necessary to perform a detailed query operation based on the specific type and name of the SCR denitration catalyst to understand its current inventory situation. During the query process, when it is found that the inventory of the SCR denitration catalyst is greater than the preset inventory, any bin location that meets the storage conditions of the SCR denitration catalyst can be flexibly selected and determined as the bin extraction position of the SCR denitration catalyst. After the extraction position is determined, based on the bin extraction position of the SCR denitration catalyst, the corresponding SCR denitration catalyst extraction instruction is generated so that the extraction operation can be performed according to the established process to ensure that the SCR denitration catalyst can be extracted in a timely and accurate manner.

[0065] S500: Sending a transfer instruction of the SCR denitration catalyst to a transportation mechanism to control the transportation mechanism to transfer the SCR denitration catalyst according to the storage location management information of the SCR denitration catalyst.

[0066] The transport mechanism refers to a device for transporting the SCR denitrification catalyst, which can be a conveyor belt or a mechanical gripper.

[0067] It should be noted that in the management of SCR denitrification catalysts, circulation refers to the entire process of catalyst movement from production to use and then to maintenance or replacement. It covers all links of the catalyst in the supply chain, including production, procurement, storage, distribution, use, etc.

[0068] In one embodiment, step S500 specifically includes: S510, if the circulation instruction of the SCR denitration catalyst is a storage instruction, sending the storage instruction of the SCR denitration catalyst to the transportation mechanism to control the transportation mechanism to store the SCR denitration catalyst in the bin storage position of the SCR denitration catalyst; Specifically, through the user interface or automatic detection of the system, the name and type of the SCR deNOx catalyst that needs to be stored are determined, and then a storage instruction is sent to the transportation agency. The instruction includes the name and type of the catalyst and the target storage location. Then, the transportation agency automatically moves the SCR deNOx catalyst from the receiving location to the designated bin storage location according to the instruction. Then, at the bin storage location, the transportation agency places the catalyst in a predetermined order and manner to ensure the orderliness and traceability of the storage. Finally, after the storage is completed, the system records the storage information, including the storage time, location, quantity and type.

[0069] S560: If the flow instruction of the SCR denitration catalyst is an extraction instruction, the extraction instruction of the SCR denitration catalyst is sent to the transportation mechanism to control the transportation mechanism to extract the SCR denitration catalyst from the storage extraction position of the SCR denitration catalyst.

[0070] Specifically, the name and type of the SCR deNOx catalyst to be extracted is determined through the user interface or automatic system detection, and then an extraction instruction is sent to the transportation agency. The instruction includes the name, type and target extraction location of the catalyst. The transportation agency then automatically moves to the designated storage extraction location according to the instruction. The transportation agency then extracts the SCR deNOx catalyst from the storage location in a predetermined order and manner. Finally, after the extraction is completed, the system records the extraction information, including the extraction time, location, quantity and type.

[0071] In this embodiment, the automated storage and extraction of the SCR denitration catalyst is achieved, the efficiency and accuracy of catalyst management are improved, and the error rate and labor intensity of manual operation are reduced.

[0072] In one or more of the above embodiments, after step S500, the method further includes: S600, generating a circulation management list of the SCR denitration catalyst based on the storage location management information, number, name and circulation status of the SCR denitration catalyst, and the current time; S700: Send the circulation management list of the SCR denitration catalyst to the user terminal, so that the user can view the circulation information of the SCR denitration catalyst on the user terminal.

[0073] For ease of understanding, the following example is given: 1. Generate SCR denitration catalyst circulation management list

[0074] 2. Send the circulation management list to the user terminal The above circulation management list is sent to the user terminal through the network. The user terminal can be a computer, tablet or smart phone. The user logs in to a dedicated application or web platform to view the circulation information of the SCR denitration catalyst. The user can use this list to track the current location and status of the catalyst to ensure the smoothness of the supply chain and the accuracy of the inventory. In addition, the system can also provide historical circulation records, inventory warnings, automatic notifications and other functions to further improve management efficiency and response speed.

[0075] Beneficial effects of the present invention: (1) Improve management efficiency: Through the automated circulation method, the manual operation links are reduced, the management efficiency of the SCR denitrification catalyst is improved, and the processing time is reduced.

[0076] (2) Reduce operational errors: The automated system reduces the possibility of human operational errors and ensures the accuracy of information through precise speech recognition and entity naming recognition technology.

[0077] (3) Enhanced security: The use of multiple authentication methods (user name, password, and biometrics) ensures that only authorized users can send instructions, thus enhancing the security of the system.

[0078] (4) Real-time monitoring and tracking: By generating a circulation management list and sending it to the user terminal in real time, the user can monitor the circulation status of the SCR denitrification catalyst at any time, which facilitates tracking and management.

[0079] (5) Cost savings: Labor costs are reduced through automated processes, and while optimizing inventory management, losses caused by poor management may also be reduced.

[0080] (6) Data recording and auditing: The circulation management list provides detailed data records for auditing, which is helpful for subsequent data analysis and process optimization.
