[0034] To describe the continuous casting machine management method and system of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] The OPC (OLE for Process Control) server is a communication standard used in the field of industrial automation to achieve data interaction and information sharing between devices. By implementing the OPC protocol, seamless communication and data exchange between different devices and systems can be achieved, improving the reliability and flexibility of industrial automation systems, and providing rich functions such as data storage, alarm, and event handling, enabling users to more conveniently monitor, control, and manage the system.

[0036] A database management system (DBMS) is a software system used to manage and process databases. It allows users to create, maintain, and control access to databases. The DBMS provides an environment that enables users and applications to store, retrieve, and manage data. The types of databases managed include relational database management systems (RDBMS), which are based on the relational model and store data in tabular form, such as MySQL, PostgreSQL, Oracle, and SQL Server. Non-relational database management systems (NoSQL), which store unstructured or semi-structured data, such as MongoDB, Cassandra, Redis, etc. Object database management systems (OODBMS), which store objects and directly map to program objects in the database, such as db4o. XML database management systems (XML DBMS), which store and query XML data, such as eXist-db.

[0037] OCR (Optical Character Recognition) technology is a technology that converts the text content in an image into editable and searchable digital text. It can recognize printed fonts, handwritten fonts, and even complex table and graphic content in pictures, realizing the conversion from "image" to "data".

[0038] Figure 1 A flow chart of a continuous casting machine management method according to an embodiment of the present invention is shown.

[0039] like Figure 1 As shown, the continuous casting machine management method provided in this embodiment is applied to electronic equipment and mainly includes the following steps:

[0040] S110: communicating with the PLC modules of the various functional modules of the continuous casting machine through the OPC server to collect equipment information and operation data of the various functional modules of the continuous casting machine.

[0041] In the specific implementation process, because the various components, intelligent products and equipment of the continuous casting machine may come from different manufacturers and units, the equipment of different manufacturers has differences in interfaces, protocols, data formats, etc., which leads to the problem that the background service module is difficult to uniformly obtain comprehensive continuous casting equipment management related information, as well as data integration difficulties, inconsistent data standards and insufficient algorithm adaptability: different manufacturers adopt different data collection methods, and the collected field sensor signals are distributed in different sub-collection systems. These data have differences in format, structure and storage method, which makes it difficult to achieve effective integration and unified management, affecting the comprehensive analysis and utilization of data; the data generated by different equipment and systems lack unified standards in naming rules, data types, units, etc., resulting in difficulties in data integration and management in the data middle platform, and it is difficult to achieve data consistency and comparability; the present invention uses OPC technology to enable each functional module of the continuous casting machine to communicate with the PLC module in real time, collect equipment information and operation data, and meet the high requirements of the continuous casting production process for data real-time.

[0042] Specifically, to create an OPC Server connection, in the background module, first create an OPC server instance and connect it to the corresponding PLC module. Create an OPC group: Create one or more groups in the OPC server to manage data items. Add OPC items: Add items in each group, which correspond to specific data points in the PLC, such as temperature, pressure, status signals, etc. OPC technology transmits the collected data to the OPC server through devices (such as sensors, PLCs, etc.). After receiving the data, the OPC server standardizes the data according to the OPC protocol and prepares it for use by other systems. The OPC client initiates a data request to the server, such as querying the current temperature, pressure and other information. The OPC server returns the processed data to the OPC client for use by the continuous casting machine management system to establish a data dictionary for the continuous casting machine.

[0043] A PLC module generally refers to a module or part in a PLC system responsible for specific functions, such as a temperature control module, a pressure monitoring module, a data acquisition module, a signal processing module, a power supply and network module.

[0044] In the specific implementation process, it is also necessary to preprocess the collected data, including data cleaning, format conversion, etc., to ensure the accuracy and availability of the data.

[0045] It should be noted that the device information of each functional module can be automatically read by an RFID reader through RFID tags embedded at each functional module. That is to say, it is planned to embed RFID in the civil engineering structure, so that when the equipment is replaced or installed, the system can automatically collect the equipment signals.

[0046] Among them, the device information includes the model, specification, and production date of the equipment. The functional modules include a ladle turret functional module, an intermediate ladle car functional module, a mold vibration functional module, a secondary cooling spray functional module, a segment functional module, and a flame cutter functional module. It should be noted that, for example, at key parts of the ladle turret, such as the rotary shaft and the support structure, heat-resistant and vibration-resistant RFID tags are installed, and these tags can store the equipment information of the turret. The operation data includes the operation status of the ladle turret (such as whether it is running normally), the rotation angle, the speed, etc. In steel production, the ladle turret is used to transfer molten steel from the ladle to the intermediate ladle, and its operation can be monitored in real time to ensure the smooth transfer of molten steel and avoid production delays caused by equipment failures.

[0047] For the intermediate ladle car functional module, an RFID tag is installed on the intermediate ladle car, and information such as the car number, capacity, and number of uses is stored in the tag. The operation data of the intermediate ladle car functional module can include the real-time position of the intermediate ladle car, the status (such as whether it is loaded with molten steel), the temperature, etc. In continuous casting production, the intermediate ladle car is used to transport molten steel, which helps to optimize the scheduling and use of the ladle car, improve production efficiency, and at the same time can monitor the use of the ladle car and perform maintenance in a timely manner.

[0048] For the mold vibration functional module, a high-precision vibration sensor is installed on the mold, and at the same time, an RFID tag is equipped. The tag stores the equipment information and vibration parameter settings of the mold. The vibration sensor collects data such as the vibration frequency, amplitude, and acceleration of the mold in real time. By reading the equipment tag information of the mold through an RFID reader, the equipment information and status information of the mold can be obtained. The mold is an important part of the continuous caster, and its vibration state directly affects the quality of the cast slab. Online monitoring of mold vibration can be realized to timely detect abnormal vibrations and prevent defects such as sticking steel.

[0049] For the secondary cooling spray function module, RFID tags are installed at key parts of the secondary cooling spray system, such as spray nozzles and pipes. The equipment information of the spray system, spray parameters, etc. are stored in the tags. The operation data of the secondary cooling spray function module can include data such as the water spray volume, spray pressure, and spray time of the secondary cooling spray. The secondary cooling spray system is used to cool the continuous casting billet, can monitor the spray effect in real time, ensure uniform cooling of the billet, and improve the quality of the billet.

[0050] For the segment function module, RFID tags are installed in each sector of the segment. The equipment information, position, etc. of the segment are stored in the tags. The operation data of the segment function module can collect information such as the opening and closing state, position deviation, and temperature of the segment. The segment is an important part of the continuous caster, and its state directly affects the shape and quality of the continuous casting billet. Real-time monitoring of the segment can be achieved to ensure its normal operation.

[0051] For the flame cutting machine function module, RFID tags are installed at key parts of the flame cutting machine, such as the cutting head and gas source. The equipment information of the cutting machine, etc. is stored in the tags. The operation data of the flame cutting machine function module can collect data such as the cutting speed, cutting quality, and gas source pressure of the flame cutting machine. The flame cutting machine is used to cut the continuous casting billet, can monitor the cutting process in real time, ensure the cutting quality, and improve the production efficiency.

[0052] S120: Store the equipment information of each collected function module into a relational database according to the set storage database address, and store the operation data of each collected function module into a distributed database according to the set storage database address; obtain the equipment information of each function module and the operation data of each function module through the database management system.

[0053] Among them, the database management system (DBMS) is a powerful set of tools. It enables users to create, modify, and delete database structures such as tables, views, and indexes through the data definition language (DDL); the data manipulation language (DML) allows users to perform operations such as inserting, querying, updating, and deleting data in the database; the data control language (DCL) is responsible for defining the security and access control rules of the database, including user privilege and role management; transaction management ensures that database operations meet the ACID properties, namely atomicity, consistency, isolation, and durability; the query optimizer automatically optimizes query statements to improve query efficiency; the DBMS is also responsible for managing the physical storage of data and creating indexes to speed up data retrieval; providing backup and recovery functions to prevent data loss and for disaster recovery; concurrent control manages concurrent operations when multiple users access the database simultaneously to ensure data consistency; finally, the DBMS enforces data integrity constraints such as entity integrity and referential integrity to ensure the accuracy and reliability of data. These functions together ensure the efficient, secure, and stable operation of the database, supporting the data requirements of various applications and business processes.

[0054] The set storage database address can allocate independent DB addresses for each subsystem and functional module according to the storage structure of the PLC. The DB address usually consists of a DB block number and an offset. For example, DB100.DBW0 represents the 0th byte of DB block 100.

[0055] S130: Analyze the device information of each functional module and the operation data of each functional module to generate control instructions for each functional module of the continuous casting machine.

[0056] In the specific implementation process, it is achieved through the background module. The specific processing methods can include parsing the collected raw data into available information, such as converting sensor readings into actual physical measurements. Performing logical judgments based on the parsed data, such as comparing the actual value with the set value to detect abnormal situations. Generating corresponding control commands based on the results of data processing and analysis, such as adjusting device parameters, starting or stopping devices, etc.

[0057] Exemplary illustration: The background module formulates corresponding control strategies and algorithms according to the requirements of the continuous casting process and the characteristics of the equipment, such as variable frequency speed control technology, full-automatic water distribution control algorithm in the secondary cooling zone, etc. Using PLC programming, specific control commands are generated according to the control strategy. For example, ladder diagrams or instruction lists are used to write program logic, and modular / structured programming methods are adopted to achieve respective control functions. The continuous casting strand automatic tracking technology is realized. The PLC automatically calculates and completes full-automatic control according to the number of pulses sent by the encoder, such as straightening machine / straightening rolls, water distribution in the secondary cooling zone, motor speed measurement, and billet length measurement. The flame cutting machine is automatically controlled to realize the automatic control of billet cutting according to real-time data.

[0058] In the specific implementation process, the control scheme can be determined for the obtained continuous casting machine data through methods such as supervised learning models, unsupervised learning models, time series analysis models, etc. A machine learning model is a mathematical structure or algorithm that can learn and infer useful information from input data, and then make predictions or decisions on new data. In the field of machine learning, the model is established by training on existing data. This training process involves optimizing the model parameters to enable it to best fit the training data and is expected to also show good generalization ability on unknown data. For example, artificial neural network (ANN), random forest, clustering algorithms (such as K-means, hierarchical clustering, etc.), long short-term memory network (LSTM). In addition, it is also necessary to preprocess the data (such as denoising, normalization, etc.) and select appropriate feature engineering methods to extract key features that contribute to model prediction. By training and testing the model, continuously optimizing the model parameters, and finally realizing the determination of the operating conditions of the continuous casting machine.

[0059] S140: The control instructions of each functional module of the continuous casting machine are respectively transmitted to the PLC module of the corresponding continuous casting machine functional module through the OPC server to control the operation of the continuous casting machine equipment. That is, the control commands are sent to the PLC module through OPC communication to perform corresponding operations.

[0060] S150: Analyze the equipment information and operation data of each functional module. While generating the control instructions of each functional module of the continuous casting machine, it also includes generating operation warning information. The control instructions and operation warning information of each functional module of the continuous casting machine are displayed through the user interface (not shown in the figure). As Figure 2 shown, implement feedback control, adjust the control parameters according to the actual operation data, and realize closed-loop regulation to keep the continuous casting machine equipment moving at a specified position or speed.

[0061] The background module is also responsible for monitoring the OPC communication status and the operating status of the PLC module; monitoring the connection status with the PLC module to ensure the continuity and stability of data communication; performing fault diagnosis and taking corresponding recovery measures when detecting anomalies or errors; regularly backing up critical data to prevent data loss and ensuring data security during the OPC communication process by using encryption and authentication mechanisms.

[0062] In a specific embodiment, the user interface is implemented by being displayed on a mobile terminal through a mobile application. The mobile terminal is provided with a camera and OCR. Aiming at the following drawbacks existing in the prior art: 1) In the aspect of device identification information collection in traditional systems, manual entry is mostly adopted, which is inefficient and error-prone. 2) When the device goes offline accidentally or relevant production information changes, it is easy to be overlooked by manual operation, with high requirements for personnel, and it is difficult to ensure the timeliness and accuracy of information; 3) And the on-site operation environment is complex. The transmission module of the device management system architecture often adopts wired transmission, or manual paper records and entry into the electronic system. 4) Wired transmission is restricted in occasions where wiring is difficult or the device moves frequently, while manual recording and entry are prone to missing device online / offline system information, as well as issues regarding the traceability and authenticity of device-related information. The present invention can achieve more efficient and accurate device information collection and management through a mobile terminal using a mobile application and OCR technology. Specifically, a mobile application suitable for tablets and mobile phones is developed. The application can include a data entry interface, allowing on-site personnel to directly enter data on the mobile device. And the data entered on the mobile terminal needs to be synchronized to the central database. This can be achieved through a wireless network connection to ensure real-time data update and storage. For example, by using the camera and OCR technology on a mobile terminal (such as a smart phone or a tablet), device identification information can be directly scanned and automatically converted into digital text, greatly reducing the workload of manual entry and at the same time reducing the error rate caused by manual operation. Through OCR technology, device identification information, including two-dimensional codes, barcodes or printed text on the device, can be quickly and accurately collected, realizing the rapid identification and information registration of the device, and optimizing the device management process. When the device goes offline accidentally or production information changes, on-site personnel can quickly use the mobile terminal to re-scan the device identification and update the information in real time to ensure the timeliness and accuracy of the system data. After adopting OCR technology, there is no longer a need for personnel to have a high level of typing input skills, and information collection can be completed only through a simple scanning operation, reducing the skill requirements for operators. The collected data can be directly stored in the database for subsequent query, analysis and traceability, improving the efficiency and quality of data management. Combining OCR technology and mobile applications can further enhance the intelligent management level of the continuous casting machine, realize the digitization and automation of the production process, and improve production efficiency and product quality. Through such a device management mode, all-round data collection, control and intelligent push decision-making of the electromechanical equipment of the continuous casting machine are realized, and a double closed-loop for continuous casting equipment management is achieved.

[0063] Such as Figure 3As shown in the figure, the present invention provides a continuous casting machine management system, which performs voice recognition by using the continuous casting machine management method as described above. According to the functions achieved, the continuous casting machine management system 200 may include a data acquisition unit 210, a data processing unit 220, and an operation control unit 230. The units of the present invention can also be referred to as modules, which refer to a series of computer program segments that can be executed by a processor of an electronic device and can complete fixed functions, and are stored in the memory of the electronic device.

[0064] In this embodiment, the functions of each module / unit are as follows:

[0065] The data acquisition unit 210 is used to communicate with the PLC modules of each functional module of the continuous casting machine through the OPC server, so as to acquire the device information and operation data of each functional module of the continuous casting machine;

[0066] The data processing unit 220 is used to store the device information of each functional module collected into a relational database according to the set storage database address, and store the operation data of each functional module collected into a distributed database according to the set storage database address; obtain the device information and operation data of each functional module through the database management system;

[0067] The operation control unit 230 is used to analyze the device information and operation data of each functional module, generate control instructions for each functional module of the continuous casting machine; and transmit the control instructions of each functional module of the continuous casting machine to the PLC module of the corresponding continuous casting machine functional module through the OPC server to control the operation of the continuous casting machine equipment.

[0068] For the continuous casting machine management system of the present invention, through the application of OPC technology, each functional module of the continuous casting machine can communicate with the PLC module in real time, acquire device information and operation data, meeting the high requirements for data real-time performance in the continuous casting production process; by storing device information in a relational database and operation data in a distributed database, effective management and rapid retrieval of data are achieved, improving the efficiency of data processing; by optimizing the data acquisition, storage, analysis, and control processes, the intelligent management level of the continuous casting machine is significantly improved, and the continuous casting production process is automatically controlled to ensure the quality and production efficiency of the cast billets. The present invention can effectively solve the adaptation problem between the existing intelligent management algorithm and the complex process and changing working conditions of the continuous casting machine, as well as the real-time performance problem of the data acquisition and transmission system, thereby improving the effect of intelligent management in practical applications and giving full play to the technical effects of optimizing the continuous casting production process and improving the efficiency of continuous casting machine equipment of the present invention.
