Problems solved by technology
The workpiece cannot actively negotiate with the manufacturing unit and independently determine its own processing process, and has not realized the "intelligence" of the workpiece itself
[0006] In addition, all the data in the existing technology are stored on the data server in the background, and the manufacturing system needs to operate the database in real time, which requires the entire manufacturing system to be reliably connected to the network anytime, anywhere, which cannot be guaranteed in many manufacturing environments

Embodiment Construction
[0033] A method for realizing an intelligent manufacturing system by utilizing a storage type RFID tag, comprising the following steps:
[0034] Step 1. Store the data content in the storage RFID tag. The stored content includes three parts: the ID code of the workpiece, the basic manufacturing information of the workpiece, and the detailed manufacturing information index table of the workpiece. Refer to figure 1 :
[0035] Using relational algebra to express the label content as:
[0036] tag i ={P_ID i , B_INFO i , Index_F_INFO i}
[0037] in:
[0038] P_ID i is the ID code of the workpiece i, which is a unified code for the workpiece manufactured in the workshop, and has unique indexing for the workpiece.
[0039] B_INFO i The basic manufacturing information for the workpiece is to reduce the amount of communication data in the system and realize the transformation of the manufacturing system from centralized control to decentralized enhanced production. The basic...

A method for realizing an intelligent manufacturing system using a storage type RFID tag, in which the ID code of the piece, the basic manufacturing information of the workpiece, and the detailed manufacturing information of the workpiece are stored in the storage type RFID tag; the database of the intelligent workpiece and the intelligent manufacturing system is established by using the storage type RFID tag The dynamic mapping relationship between them; the storage unit storage RFID tag of the smart workpiece and the workpiece entity are physically bound to realize that each smart workpiece has an independent storage unit, and finally realize the intelligence of the manufacturing unit and the intelligence of the transmission equipment ; The present invention utilizes the storage type RFID tag to realize the intelligence of the workpiece, and in the manufacturing environment without network, it can still ensure the smooth progress of the workpiece manufacturing process. to adjust the processing process.
Description
technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a method for realizing an intelligent manufacturing system by using a storage type RFID tag. Background technique [0002] The concept of intelligent manufacturing is proposed in Industry 4.0, and its basic requirements are: the workpiece can actively "negotiate" with the manufacturing unit in real time during the processing process, so as to determine the processing operation that should be performed in the next step. However, there is currently no uniform standard for the specific implementation of this model. The existing technologies that can be used mainly include: [0003] 1) Real-time information collection system based on barcode technology. This is the most common implementation method. The barcode is directly pasted on the surface of the workpiece. When the workpiece arrives at a station, the operator manually scans the barcode information, and the ma...
