Detailed Description
A digital twin method for ship segment workshop material management is characterized in that a twin system synchronous with a physical layer is generated in information world accurate mapping through real-time perception and monitoring of segment workshop material and middleware related information. The method comprises the steps of material/middleware entering and exiting, and data acquisition and storage of changes of forms and positions of the material/middleware in a segmented workshop. The required data and the storage format thereof are given according to the requirement of material management twinning; automatically acquiring attribute and position data of the materials/middleware according to RFID labels carried by the materials/middleware and RFID readers arranged at stations and stacked positions; and respectively providing a backtracking algorithm and a front-searching algorithm according to historical data of the materials/middleware, wherein the materials/middleware can still backtrack and front-search related information data after being welded and cut.
When the materials/middleware are circulated in the segmented workshop or become new materials/middleware through welding and cutting, the system forms new materials/middleware data according to the current state data of the materials/middleware and circulation, welding and cutting actions and stores the new materials/middleware data: when the material/middleware has no upper-level material/middleware information, the material/middleware enters a segmented workshop; when the material/middleware does not define a new storage position, indicating that the material/middleware moves out of the segmented workshop; when the material/middleware time of the previous level recorded adjacently is the same, the material/middleware circulates in the segmented workshop without other changes; when a new material/intermediate piece is formed when welding or cutting of the material/intermediate piece occurs, the new material/intermediate piece record is not only included, but also the previous material records the source thereof.
Specifically, during material/middleware state data acquisition, the related attributes obtained by scanning the two-dimensional codes and the bar codes of the materials/middleware can be obtained. The RFID reader-writer arranged at the designated position (such as a station and a stacking position) can be used for reading the RFID label stuck on the material/intermediate piece to acquire the related attribute of the material/intermediate piece and the current position of the material/intermediate piece. The data of the states, positions and the like of the materials/middleware are transmitted to a background data server through a network, the data are stored in a database system, specific attribute data are shown in a database table chart 1, employee table replayeetable mainly stores work number, name, mobile phone number, login password and role data of operators, and related information is stored as operators after verification of the login system. The staff work numbers are unique identifications, and staff identities are divided into two types according to different functions: "charge" and "reployee" (manager and operator), wherein the manager mainly completes system basic data management and material backtracking, foreline and other statistical analysis, and the operator mainly completes data record of material change in workshops; the material attribute table mainly comprises data such as material numbers, names, specifications, sizes, execution standards, remark descriptions and the like, and the material numbers are used as unique identification codes for distinguishing materials; the material position table positionability mainly stores material storage places and stations in workshops, and comprises data such as numbers, names, logical position names, specific coordinates, remark descriptions and the like; the pallet attribute table pallet is used for keeping pallet attributes and mainly comprises basic data such as pallet numbers, names, types, specifications, bearing, dead weights, pallet states and the like; the material real-time record table poschangerecordtable is a database table for recording position change in a material workshop, and relates to a series of operations of warehouse entry and exit, internal circulation, cutting, combination and the like. The method specifically comprises a material number, a material position/tray number, a storage position type, an operator number, a previous-stage material number, a registration time and the like. Wherein the number of the last-stage material in the record is 0 when the material is put in storage, and the storage position recorded when the material is put out of storage is 0; the real-time recording table of the tray is used for recording the position change of the tray in a workshop, and specifically comprises the following steps: tray number, stack number, in-out stack flag, operator number, and registration time.
The software implementation part comprises functions of RFID data uploading, attribute data acquisition uploading, real-time data statistics and display of materials/middleware, material/middleware backtracking and the like. The system data comprises basic data and real-time data, wherein the basic data comprises operator attribute data, material/middleware attribute data, tray attribute data and station/heap attribute data, and the real-time data comprises material/middleware real-time position data and tray real-time position data. Each of the operators, materials/middleware, trays and stations/stackers has a unique ID.
The RFID data uploading mainly realizes data acquisition of partial materials/middleware and storage trays, when materials/middleware and trays with RFID tags enter the range of an RFID reader-writer, the RFID reader-writer reads tag data (the IDs of the materials/middleware or trays), the tag data and the positions of the reader-writers are uploaded to a background database, and the system can know the attributes and the current positions of the materials, the middleware and the storage trays according to the pre-stored basic data and the acquired RFID data and automatically stores the attributes and the current positions of the materials, the middleware and the storage trays.
When the materials/middleware are required to circulate in the segment workshop due to the production and processing flow (including entering the segment workshop and moving out of the segment workshop), an operator firstly acquires the properties of the materials and the middleware through a QR two-dimensional code (the ID of the materials/middleware or a tray), then records the new positions of the materials and the middleware through software, and when the materials and the middleware have no previous-stage materials and middleware information, the materials/middleware are indicated to enter the segment workshop, and when the materials/middleware have no clear new storage position, the materials/middleware are indicated to move out of the segment workshop.
Because of the requirement of processing and production, new materials/intermediates are generated in the production process, such as a plurality of materials/intermediates are assembled and welded to form new materials/intermediates, or the materials/intermediates are cut into a plurality of new materials/intermediates, so that real-time positions of the new materials/intermediates are recorded, and sources of the new materials/intermediates are recorded for tracing the materials/intermediates. The evolution of the material/middleware in the segment shop is shown in fig. 2. FIG. 2A shows a schematic view of the material/intermediate piece with position change only in the segment shop, without welding and cutting; FIG. 2B shows not only the change in position of the materials/intermediaries in the segment shop, but also the welding, i.e. the combination of multiple materials/intermediaries into a new material/intermediaries; FIG. 2C shows not only the change in position of a material/intermediate piece within a segment shop, but also the cutting, i.e., one material/intermediate piece is cut to form a plurality of new material/intermediate pieces; fig. 2D shows not only the change in position of the material, the intermediate piece, but also the welding and cutting in the segment shop.
In order to obtain the evolution and position change conditions of the materials/middleware in the segmented workshop, backtracking and front cable can be carried out according to the given material/middleware ID and the obtained data, so that the complete evolution process of the materials/middleware in the segmented workshop with time change of the form and position can be constructed.
The material/middleware backtracking means that the material/middleware is changed from the raw material entering the subsection workshop to the storage position at the current moment according to the given material/middleware ID in time sequence, and related data such as people, positions, raw materials/middleware/accessories and the like involved in the manufacturing process are listed.
Firstly, inquiring according to the condition of the current material IDmatrix = = material/middleware ID in a Poschanglecordtable table, and sequencing the records meeting the condition according to the registration time logtime from the near to the far. If the upmate= =material/middleware ID in the record indicates that the material has no morphological change and only has position change in the manufacturing process, the data related to the position change of the material/middleware can be listed in sequence until the last record meeting the condition is the end of the warehouse entry record of the material/middleware; when the previous level material idupimid is different from the material/middleware ID, it is indicated that the current material is cut or welded by the previous level material idupimid material, and before that, the given material/middleware is absent, in order to further acquire the composition information of the material/middleware, it is necessary to sequentially trace back the upmatid as a trace back material/middleware ID, and sequentially list the data related to the position change of the material/middleware until the last record meeting the condition is a material/middleware warehouse entry record. The specific flow is shown in fig. 3.
The material/middleware front rope refers to that according to a given material/middleware ID, the storage position of the material/middleware from the first occurrence to the current moment is changed according to time sequence, and related data such as people, positions, raw materials/middleware/accessories and the like involved in the manufacturing process are listed.
Firstly, searching according to the condition of the previous-level material IDupmate= material/middleware ID in a Poschanglecordtable table, and sequencing the records meeting the condition according to the registration time logtime from far to near. If the current material IDmatid= material/middleware ID in the record indicates that the material does not change in form and only changes in position in the manufacturing process, the data related to the material/middleware position change can be listed in sequence until all records meeting the conditions are traversed or until the material/middleware delivery record is traversed; when the matrix ID is different from the material/middleware ID, the current material is cut or welded into a new material/middleware, and in order to further acquire the evolution information of the material/middleware, the matrix ID needs to be sequentially used as a backtracking material/middleware ID to continuously backtrack, and the data related to the position change of the material/middleware is sequentially listed until all records meeting the conditions are traversed or the materials/middleware are traversed until the delivery records of the material/middleware are completed. The material/middleware front rope flow is shown in fig. 4.
As shown in fig. 5, the full life cycle of the materials in the ship segment workshop means that the raw materials are started from warehouse entry, and after in-warehouse circulation and processing technology treatment, the ship middleware is produced, small assembly, assembly and the like, and the warehouse exit is finished. Warehouse entry raw materials include, but are not limited to, plates, profiles, pipes, fittings, and the like. The raw materials put in warehouse are cut, welded and installed according to the manufacturing process and flow. In the process of producing the ship middleware, the small assembly and the assembly, all relatively independent parts generated in the middle are uniquely identified by QR two-dimensional codes, RFID labels and the like. And record its associated information in the system, including but not limited to: storage locations, operators, operating times, etc., wherein the storage locations may be stations, stacks, trays. For new components formed by welded installation, it is also necessary to record the identification codes of their constituent sub-components; for the cut parts, each cut part needs to record the identification code of its parent part. Therefore, the full life cycle data of the materials in the ship segmentation workshop can be completely recorded through the preamble, the follow-up identification code and the storage position of the components, so that a management twin system is constructed, the material states in the ship segmentation workshop can be checked and counted in real time, the production process can be traced back according to the material identification code, and data support is provided for follow-up production, monitoring management and maintenance of ship marine equipment.
The invention discloses a digital twin method for material management in a ship segmentation workshop, which comprises the steps of material input and output storage, data acquisition, storage and statistics of changes of forms and positions of materials in the segmentation workshop, material backtracking and front rope. In the process of ship segment workshop segment production, a twin system synchronous with a physical layer is generated in the information world through real-time perception monitoring of related information of segment workshop materials and middleware. The method provided by the invention has the advantages of reasonable planning, real-time tracking and integrated management and control of the twin system, and process management capability is improved.
