Description
Technical Field
[0001] This invention relates to the field of casting automation technology, specifically to a multi-terminal interconnected casting system. Background Technology
[0002] Casting is an industry with a high degree of personalization in its production processes. On the one hand, the lack of standardized construction standards in the early days led to significant differences in the layout of each foundry, and even different production lines within the same foundry. On the other hand, the diverse production processes in the casting industry make standardization difficult. Therefore, it is challenging to design a universal automated system that can be adapted to all manufacturers.
[0003] Existing automated casting systems have significant shortcomings in functional integration, scalability, and multi-device collaboration, making it difficult to meet the needs of complex production scenarios. The main technical problems are as follows: 1. Limited application scenarios and functions, only capable of automating the collection of data from a single furnace body, resulting in a lack of information sharing between devices, making it suitable only for simple application scenarios; 2. The casting production process covers multiple stages, including raw material processing, smelting, post-furnace treatment, pouring, and quality inspection. The equipment in each stage is scattered and the data is independent, resulting in a lack of statistical dimensions and an inability to fully reflect many details of the production process. Summary of the Invention
[0004] The purpose of this invention is to provide a multi-terminal interconnected casting system, which aims to solve the problems of dispersed equipment, isolated data, and inefficient collaboration in existing casting production.
[0005] Specifically, this is achieved through the following technical solution: a multi-terminal interconnected casting system, comprising: Material pool area, wherein a feeding crane is provided; The furnace area is equipped with multiple smelting furnaces. Each smelting furnace corresponds to a feeding line, a furnace front control console, and a furnace front temperature measuring gun. The furnace front temperature measuring gun is wirelessly connected to the corresponding furnace front control console. Each furnace front control console shares data through a separate channel. The material transported by the feeding trolley can be transferred to any feeding line for smelting operations. The post-furnace process area is equipped with a spheroidizing wire feeding station and a furnace exit crane. The casting area is equipped with multiple transfer lines, and molten metal from any smelting furnace can be transferred to any transfer line for casting operations via a furnace tapping crane; The post-processing and quality inspection area is equipped with a universal mechanical property testing machine, a metallographic analyzer, and a spectrometer. The furnace front execution terminal can be connected to any online furnace front control console and realize data interaction. The furnace front execution terminal includes a charging hook scale located in the material pool area, a furnace front alloy scale located in the furnace platform area, a furnace outlet hook scale and a furnace back alloy scale located in the furnace back process area, and a casting alloy scale and a casting temperature measuring gun located in the casting area. The charging hook scale is hoisted on the charging crane, and the furnace outlet hook scale is hoisted on the furnace outlet crane. The management terminal includes a computer web terminal and a mobile terminal. It establishes associations with various block devices through data interaction and permission control, realizing full-process data collection, equipment interconnection and centralized management of the casting production line.
[0006] Preferably, the furnace-front execution terminal establishes communication with any online furnace-front control console through a dynamic frequency sweep interconnection mode. The logic of the dynamic frequency sweep interconnection mode is as follows: S1. All furnace-front control consoles are connected to the same network via network cables. Each furnace-front control console is configured with a unique logical channel identifier, which is sequentially assigned the numbers 0, 1, 2, ... n. S2. After any furnace front execution terminal is powered on, it will scan each channel in sequence starting from channel 0. When the target channel is scanned, the furnace front console corresponding to the channel receives the handshake request of the furnace front execution terminal and determines whether the current furnace front execution terminal meets the handshake requirements. S3. Once a handshake connection is successfully established, the furnace front control console will broadcast the received data from the furnace front execution terminal in real time to other online furnace front control consoles within the network via the network cable, thereby achieving data sharing among the furnace front control consoles.
[0007] Preferably, the logic for the furnace front control console to determine whether the current furnace front execution terminal has met the handshake requirements is as follows: If the furnace front control console detects that the PID of the current furnace front execution terminal has been bound to this device, it replies with a SynAck frame to the current channel. After receiving the SynAck frame, the furnace front execution terminal records the PID of the corresponding furnace front control console and the logical identifier of the channel, and replies with an Ack frame to confirm that the channel is the current working channel, thus completing the handshake connection. If the furnace front console finds that the PID of the current furnace front execution terminal is not bound to this device, the furnace front console will not reply with a SynAck frame. The current furnace front execution terminal will scan the next channel in sequence until it finds an online furnace front console that has bound its PID and completes the handshake connection. If none of the furnace front control consoles can find the PID of the furnace front execution terminal, the furnace front control console with sequence number n will send a non-binding prompt frame to the management terminal. After the management terminal verifies the identity information of the furnace front execution terminal, the furnace front control console with sequence number n will associate and store the PID of the furnace front execution terminal with its own equipment information to complete the initial binding, and then reply with a SynAck frame to allow the furnace front execution terminal to complete the handshake connection according to the current channel.
[0008] Preferably, it also includes a casting production process management system, which includes an inventory management module, a quality management module, a product management module, and a process formula management module. Each management module achieves information synchronization with the management terminal through data interaction.
[0009] Preferably, the operation nodes and data interaction logic of the process steps within the material pool area are as follows: When raw materials are received into the warehouse, the feeding hook scale automatically collects the weight data of the raw materials and automatically enters the data into the inventory management module; After the raw materials are placed into the designated material pool in the casting production workshop, the location information of the material pool is automatically entered into the inventory management module, forming a weight-location associated inventory record.
[0010] Preferably, the operation nodes and data interaction logic of the process steps within the furnace area are as follows: Before smelting, the feeding line extracts raw materials from the material pool and puts them into the smelting furnace, automatically triggering the outbound process of the inventory management module and updating the inventory data in real time. During the smelting and charging stage, the alloy scale in front of the furnace collects the smelting and charging weight data and enters it into the process formula management module in real time. During the furnace melting stage, the furnace alloy scale accurately weighs the added recycled material, and the weighing data is entered into the process formula management module in real time. The composition data of molten metal during the furnace melting stage is automatically entered into the process formula management module through the connected spectrometer and furnace thermal analyzer. The furnace exit temperature at the end of the furnace melting process is automatically collected by the furnace temperature measuring gun and entered into the process formula management module. The weight of the furnace at the end of the furnace melting process is automatically collected by the alloy scale and entered into the process formula management module.
[0011] Preferably, the operation nodes and data interaction logic of the process steps in the post-furnace process zone are as follows: After the molten metal is tapped from the furnace, the materials added after the furnace are weighed using a furnace alloy scale, and the material addition data is automatically entered into the process formula management module. The furnace control console synchronously sends data on furnace weight, furnace temperature, and metal composition to the spheroidizing wire feeding station. The spheroidizing wire feeding station operates automatically according to the received data, and the operating data and feeding data are automatically entered into the process formula management module. After the furnace charging is completed and the slag removal operation of the molten iron ladle is performed, the weight data of the current molten metal is collected by the alloy scale at the furnace and the final weight of the molten metal is confirmed. This weight data is automatically entered into the process formula management module.
[0012] Preferably, the operation nodes and data interaction logic of the process steps within the casting zone are as follows: The pouring station measures the temperature of the molten metal using a pouring temperature gun, and the temperature data is automatically entered into the process formula management module. During the casting process, the furnace exit hook scale monitors the weight change of the casting in real time, and the weight change data is automatically entered into the process formula management module; After casting is completed, the casting status is confirmed by the casting alloy scale. The system automatically calculates the time from the end of the furnace post-processing to the completion of casting. The time data and the casting completion status are automatically entered into the process formula management module. After casting is completed, the weight of the molten metal returned to the furnace is collected by the casting alloy scale, and the return weight data is automatically entered into the process formula management module.
[0013] Preferably, the operation nodes and data interaction logic of the post-processing and process steps within the quality inspection area are as follows: Raw material quality inspectors enter finished raw material data and first-time scrap data into the quality management module through the management terminal. The system automatically synchronizes the data to the inventory management module and updates the inventory of finished raw materials / scrap. The testing laboratory quality inspectors input metallographic, spectral composition, chemical composition and mechanical property test data into the quality management module, which automatically generates a quality inspection report. The quality control personnel in the testing laboratory enter the data of qualified raw finished products and secondary waste products into the quality management module through the management terminal. The system automatically synchronizes the data to the inventory management module and updates the qualified inventory and the quantity of final waste products.
[0014] Preferably, it also includes a display terminal, which includes a large screen in the central control room, a large screen for comprehensive display of material addition and batching in front of the furnace located on one side of the material pool area, a large screen for comprehensive display of post-furnace process located on one side of the casting area, and a display screen for the furnace discharge hook scale located on one side of the post-furnace process area, so as to realize the visual monitoring and management of the entire production process.
[0015] After adopting the above technical solution, the beneficial effects of the present invention are: This application improves the standardization and automation of the casting production process by achieving full-process data collection, equipment interconnection, and centralized control. It also supports information sharing and collaborative work across multiple furnaces and terminals, making it suitable for large-scale casting plants. Automatic interconnection between mobile terminals and the control console is achieved through a dynamic frequency scanning mode, enabling real-time data sharing and eliminating information silos. A closed-loop data recording system covers the entire process from raw material warehousing to finished product quality inspection, allowing for rapid location and traceability of quality issues.

[0018] 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 specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Those skilled in the art will recognize that the invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples of it.
[0019] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the invention. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0020] A multi-terminal interconnected casting system is based on functional zoning as hardware, multi-terminal interconnection as data link, and a full-process management system as control core. The system consists of three major modules: physical functional area, terminal system, and casting production full-process management system. Each module achieves data interaction through Ethernet or industrial bus.
[0021] Reference Figure 1 and Figure 2 The physical functional area is divided into five core areas according to the casting production process: material pool area, furnace platform area, post-furnace process area, pouring area, and post-processing and quality inspection area. Each area is equipped with dedicated production equipment to form a continuous production chain.
[0022] The terminal system includes a management terminal and a display terminal, which respectively undertake remote control and on-site data visualization functions. The management terminal includes a computer web terminal and a mobile terminal, which establishes connections with various block devices through data interaction and access control, realizing full-process data collection, equipment interconnection and centralized control of the casting production line.
[0023] The display terminals include four types of display devices deployed near each other according to functional zones. A large central control screen is deployed in the workshop's central control room, displaying full-process production data (progress of each area, equipment operating status, and anomaly warnings), supporting global monitoring. A comprehensive post-furnace process display screen is deployed on one side of the casting area, displaying the progress of molten iron transfer, casting temperature, and transfer line load, supporting coordination in the casting process. A comprehensive pre-furnace charging and batching display screen is deployed on one side of the material pool area, displaying raw material inventory, real-time location of the charging crane, and material waiting requirements for each charging line, assisting in material pool area operations. A furnace-mounted crane scale display screen is deployed on one side of the post-furnace process area, displaying the real-time weight of molten iron measured by the furnace-mounted crane scale and the corresponding smelting furnace identification, facilitating on-site confirmation.
[0024] The casting production end-to-end management system serves as the core of data integration and business control, comprising four core functional modules. These modules work together to achieve a closed-loop data flow throughout the entire process: the inventory management module manages the inventory status of raw materials, finished products, and scrap; the quality management module stores and analyzes quality inspection data; the product management module enables full lifecycle traceability of castings; and the process formula management module stores and verifies process parameters for each production stage.
[0025] The material pool area serves as the starting point for material storage and initial transfer, distributing materials to any feeding line in the furnace area to provide raw material supply for the smelting process. It is the raw material entry point for casting production. A feeding trolley is installed within the material pool area, covering the entire area via a pre-set track. It can move autonomously or according to scheduling instructions to designated raw material storage areas based on smelting needs, solving the problems of low efficiency and high labor intensity associated with traditional manual transfer. An electromagnet is mounted on the feeding hook scale of the feeding trolley to handle ferromagnetic materials, allowing for rapid adsorption without manual hooking.
[0026] The operation nodes and data interaction logic of the process steps within the material pool area are as follows: When raw materials are received into the warehouse, the feeding hook scale automatically collects the weight data of the raw materials and automatically enters the data into the inventory management module; After the raw materials are placed into the designated material pool in the casting production workshop, the location information of the material pool is automatically entered into the inventory management module, forming a weight-location associated inventory record.
[0027] The furnace area is the core area for material smelting. It contains one alloy weighing scale and multiple smelting furnaces. Each furnace receives raw materials transferred from the material pool area via a dedicated feeding line. The feeding line includes feeding trolleys that travel along tracks laid out along the furnace layout for precise feeding. Materials transported by the overhead feeding trolley can be transferred to any feeding trolley and then delivered to the corresponding smelting furnace for smelting.
[0028] Each smelting furnace corresponds to one furnace-front control console and one furnace-front temperature measuring gun. All furnace-front control consoles are connected to the same network via network cables, and each furnace-front control console shares data through a separate channel to avoid mutual interference between multiple furnace-front control consoles.
[0029] The operation nodes and data interaction logic of the process steps within the furnace area are as follows: Before smelting, the feeding line extracts raw materials from the material pool and puts them into the smelting furnace, automatically triggering the outbound process of the inventory management module and updating the inventory data in real time. During the smelting and charging stage, the alloy scale in front of the furnace collects the smelting and charging weight data and enters it into the process formula management module in real time. During the furnace melting stage, the furnace alloy scale accurately weighs the added recycled material, and the weighing data is entered into the process formula management module in real time. The composition data of molten metal during the furnace melting stage is automatically entered into the process formula management module through the connected spectrometer and furnace thermal analyzer. The furnace exit temperature at the end of the furnace melting process is automatically collected by the furnace temperature measuring gun and entered into the process formula management module. The weight of the furnace at the end of the furnace melting process is automatically collected by the alloy scale and entered into the process formula management module.
[0030] The post-furnace process area is equipped with a spheroidizing wire feeding station, a furnace trolley, and a furnace alloy scale. The furnace trolley is equipped with a furnace hook scale for lifting and transporting the smelted products.
[0031] The operation nodes and data interaction logic of the process steps in the post-furnace process area are as follows: After the molten metal is tapped from the furnace, the materials added after the furnace are weighed using a furnace alloy scale, with manual confirmation. The material addition data is then automatically entered into the process formula management module. For a spheroidizing wire feeding station equipped with communication capabilities, the furnace front terminal can synchronously send data on furnace output weight, furnace output temperature, and metal composition to the spheroidizing wire feeding station. The spheroidizing wire feeding station will then operate automatically based on the received data, and the operating data and feeding data will be automatically entered into the process formula management module. After the post-furnace charging is completed and the slag removal operation of the molten iron ladle is performed, the final weight of the molten metal is confirmed by manually checking the weight of the current charging hook scale using the post-furnace alloy scale. The data is then automatically entered into the process formula management module. The process formula management module calculates the losses in the process after the furnace is tapped by adding the weight of the post-furnace charging to the weight after slag removal. The process formula management module calculates the time consumed in the post-furnace processing stage based on the automatically determined tapping time and the time taken to confirm the weight of the molten metal after slag removal.
[0032] The casting area is equipped with alloy weighing scales, casting temperature measuring guns, and multiple transfer lines. Molten metal produced from any smelting furnace can be transferred to any transfer line via a furnace trolley for casting operations. The transfer lines include molten iron transfer cars, which run along casting car tracks laid out along the casting station layout to achieve precise material feeding.
[0033] The operational nodes and data interaction logic of the process steps within the casting zone are as follows: The pouring station measures the temperature of the molten metal using a pouring temperature gun, and the temperature data is automatically entered into the process formula management module. During the casting process, the furnace exit hook scale monitors the weight change of the casting in real time, and the weight change data is automatically entered into the process formula management module; After casting is completed, the casting status is confirmed by the casting alloy scale. The system automatically calculates the time from the end of the furnace post-processing to the completion of casting. The time data and the casting completion status are automatically entered into the process formula management module. After casting is completed, the weight of the molten metal returned to the furnace is collected by the casting alloy scale, and the return weight data is automatically entered into the process formula management module.
[0034] The post-processing and quality inspection area is equipped with a universal mechanical property testing machine, a metallographic analyzer, and a spectrometer for the quality inspection of castings.
[0035] The operation nodes and data interaction logic of the post-processing and quality inspection processes are as follows: Raw material quality inspectors enter finished raw material data and first-time scrap data into the quality management module through the management terminal. The system automatically synchronizes the data to the inventory management module and updates the inventory of finished raw materials / scrap. The testing laboratory quality inspectors input metallographic, spectral composition, chemical composition and mechanical property test data into the quality management module, which automatically generates a quality inspection report. The quality control personnel in the testing laboratory enter the data of qualified raw finished products and secondary waste products into the quality management module through the management terminal. The system automatically synchronizes the data to the inventory management module and updates the qualified inventory and the quantity of final waste products.
[0036] The furnace-front execution terminal consists of a charging hook scale, a furnace-front alloy scale, a furnace-out hook scale, a furnace-back alloy scale, a casting alloy scale, and a casting temperature measuring gun. When any furnace-front control console is online, the furnace-front execution terminal can connect and exchange data, achieving many-to-many binding. The furnace-front temperature measuring gun is bound one-to-one to a furnace-front control console via a wireless communication module. As long as a smelting furnace requires the use of a furnace-front temperature measuring gun, its corresponding furnace-front control console will necessarily be online; therefore, there is no need to consider the scenario where the furnace-front temperature measuring gun needs to connect to multiple furnace-front control consoles.
[0037] Reference Figure 3 and Figure 4 The furnace-front execution terminal establishes communication with any online furnace-front control console through a dynamic frequency sweep interconnection mode. The logic of the dynamic frequency sweep interconnection mode is as follows: S1. Each furnace front control console is configured with a unique logical channel identifier, which is sequentially assigned the numbers 0, 1, 2, ... n; S2. After any furnace front execution terminal is powered on, it will scan each channel sequentially starting from channel 0. When the target channel is scanned, the furnace front control console corresponding to that channel receives the handshake request from the furnace front execution terminal and determines whether the current furnace front execution terminal meets the handshake requirements: S21. If the furnace front control console finds that the PID of the current furnace front execution terminal has been bound to this device, it replies with a SynAck frame to the current channel. After receiving the SynAck frame, the furnace front execution terminal records the PID of the corresponding furnace front control console and the logical identifier of the channel, and replies with an Ack frame to confirm that the channel is the current working channel, thus completing the handshake connection. S22. If the furnace front console finds that the PID of the current furnace front execution terminal is not bound to this device, the furnace front console will not reply with a SynAck frame. The current furnace front execution terminal will scan the next channel in sequence until it finds an online furnace front console that has bound its PID and completes the handshake connection. S23. If none of the furnace front control consoles can find the PID of the furnace front execution terminal, the furnace front control console with sequence number n sends a non-binding prompt frame to the management terminal. After the management terminal verifies the identity information of the furnace front execution terminal, the furnace front control console with sequence number n associates and stores the PID of the furnace front execution terminal with its own equipment information to complete the first binding, and then replies with a SynAck frame to allow the furnace front execution terminal to complete the handshake connection according to the current channel. S3. Once a handshake connection is successfully established, the furnace front control console will broadcast the received data from the furnace front execution terminal in real time to other online furnace front control consoles within the network via the network cable, thereby achieving data sharing among the furnace front control consoles.
[0038] Through the dynamic frequency sweep interconnection mode, it can support one furnace front control console to connect to multiple furnace front execution terminals at the same time, and the data can be transmitted in real time; it can support one furnace front execution terminal to connect to any online furnace front control console, ensuring that the system can still work normally when any furnace front control console is offline; data sharing between multiple furnace front control consoles ensures that the process data source is unique, reduces the amount of data uploaded to the cloud, and saves outbound bandwidth.
[0039] The embodiments described above are not exhaustive and do not limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
