Description

Technical Field

[0001] The invention relates to the technical field of intelligent numerical control workshops, and in particular to an intelligent numerical control workshop design verification system. Background Art

[0002] The intelligent CNC workshop design verification system is a system that uses digital and intelligent technologies to simulate and verify workshop design solutions. It integrates a variety of software and hardware equipment and systems, such as MES, ERP, PLM, WMS, etc., to achieve digital transformation of the workshop, improve production efficiency, reduce energy consumption, and realize paperless production, office, and management.

[0003] However, the traditional production line design first uses digital technology to build a production site model, and then conducts offline simulation and analysis to optimize the production line. This is a static design method. The traditional method lacks the drive of real-time production data, cannot comprehensively consider the production line, and cannot fully reflect the actual problems. Therefore, an intelligent CNC workshop design verification system is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent CNC workshop design verification system in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: An intelligent CNC workshop design verification system, characterized by comprising: Intelligent CNC workshop design and planning module: The design and planning module first designs and builds the virtual components required for the digital twin of the automated workshop in the virtual component design module, then performs process design in the digital process design module according to actual production needs, and arranges the automated production line in the virtual production line planning module according to the designed components and processes; after completing the construction of the digital twin, the production line planning effect and control program are verified through the virtual production line simulation debugging module and the virtual production line and real control system joint debugging module; Intelligent CNC workshop data processing center: includes database, data comparison and verification module and data transmission module; the database stores the model, category, workshop distribution and production process data of intelligent CNC equipment; Intelligent CNC workshop monitoring and acquisition modules: set up in the workshop to collect data from intelligent CNC equipment; these modules are equipped with data transmission modules and can communicate data with the processing center; Intelligent CNC workshop data comparison and verification module: Identify the intelligent CNC equipment in the intelligent CNC workshop design data to be verified, call the data in the database, compare and analyze it with the data in the design, and output the verification results; Intelligent CNC workshop data transmission module: ensures data communication between the processing center and the monitoring and acquisition module.

[0006] The intelligent CNC workshop design verification system can integrate advanced artificial intelligence technologies such as machine learning and digital twin technology to achieve more efficient and intelligent production process optimization and decision support.

[0007] The virtual component design module is the basis for building a digital twin. It is used to build a three-dimensional model of each production factor, set properties, and write internal drivers. The virtual components of the digital twin of the automated workshop mainly include transport unit virtual components, machining center virtual components, auxiliary equipment virtual components, virtual workpieces, and staff virtual components. The basic units of virtual components are component nodes, behaviors, attributes, and features. The virtual components all have a unique ID and contain a root node. The root node of the component is the basis for building features, attributes, behaviors, and sub-nodes.

[0008] The database and the data transmission module data records are in the same data format, and the data items to be verified in the target data set are modified using html. The data transmission module establishes a threshold for selecting between traditional random access (RA) resources and RA resources related to small data transmission (SDT), and when the reference signal received power (RSRP) of the downlink path loss reference is higher than the threshold, the RA resources related to the SDT are selected, and when the RSRP of the downlink path loss reference is lower than the threshold, the traditional RA resources are selected. The method includes: establishing another threshold for selecting between the two-step RA type and the four-step RA type, and when the RSRP of the downlink path loss reference is higher than the another threshold, the two-step RA type is selected.

[0009] When implementing the intelligent CNC workshop design verification system, it is necessary to consider the specific needs of the workshop, equipment selection, software system design, communication system design, and system optimization. Through these comprehensive measures, it can be ensured that the workshop's intelligent production system can operate efficiently and stably, achieving a dual improvement in production efficiency and product quality.

[0010] The intelligent CNC workshop data comparison and verification module includes the first to Nth function blocks, N is an integer greater than 1, and each of the function blocks has a corresponding address. The CNC machine tool establishes a communication connection with the control panel through Profinet, and uses the HikariCP database connection pool technology to save the comparison result in the database to generate the first version information. The first version information obtained from the database is compared with the current version information. By building a fully distributed file system HDFS, a master node hadoop-master, and three slave node hadoop-slave clusters, the first version information obtained from the database is compared with each data item in the current version information.

[0011] The data in the data processing center of the intelligent CNC workshop is uploaded to the database through the data transmission module. The data transmission module is a wireless transmission unit or a cloud server. The server end of the wireless transmission unit or the cloud server is built in the physical workshop, and the client end of the wireless transmission unit or the cloud server is built in the data management and storage module. The collected physical workshop data is sent to the data management and storage module through the wireless transmission unit or the cloud server after data analysis.

[0012] The data transmission module sends the first data to the intelligent CNC workshop data processing center, and starts timing from the time when the first data is sent, wherein the first data at least includes the data to be processed; the intelligent CNC workshop data processing center receives the first data, and starts timing from the time when the first data is received; when the value obtained by the timing of the intelligent CNC workshop data processing center reaches a preset value, the intelligent CNC workshop data processing center sends the second data to the data transmission module, wherein the second data is the data obtained after the intelligent CNC workshop data processing center processes the data to be processed; if the value obtained by the timing of the data transmission module is within the effective range of the preset value, the data transmission module allows the start of receiving the second data.
