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...

Abstract

A method for realizing an intelligent manufacturing system by using memory type RFID tags includes the following steps of: storing an ID code of a work piece, basic manufacturing information of the work piece, and detailed manufacturing information of the work piece into each memory type RFID tag; establishing a dynamic mapping relationship between each intelligent work piece and an intelligent manufacturing system data base through each memory type RFID tag; physically binding the memory unit memory type RFID tag of each intelligent work piece and a corresponding work piece entity to realize that each intelligent work piece has an independent memory unit; and finally realizing intellectualization of a manufacturing unit and intellectualization of a conveying device. According to the invention, intellectualization of the work pieces can be realized through the memory type RFID tags, and a work piece manufacturing process can be smooth in a manufacturing environment without network; and meanwhile, in the manufacturing process, the work pieces and the manufacturing system can perform a negotiation and dynamically adjust the manufacturing 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...
