A multi-unit intelligent manufacturing system with robots based on smart-rfid tags

Abstract

A multi-unit intelligent manufacturing system with robots based on smart-RFID tags, including intelligent workpieces, initialization stations, processing stations, sorting stations, intelligent warehouses and conveyor belt transportation systems, wherein the processing stations are composed of processing machine tools and measuring work The smart workpiece is equipped with a smart-RFID tag, and the production process information of the workpiece is written into the tag through the RFID reader at the initialization station. During the production process, the smart workpiece can exchange production information with the processing equipment through radio frequency signals. The sorting station realizes online sorting of different types of workpieces through the smart-RFID tag information of the smart workpieces, and the smart warehouse automatically counts the workpiece warehousing information based on the smart-RFID tag information. The control system of the intelligent manufacturing system is composed of independent control modules. In addition to automatically performing related operations, each module can also receive control instructions sent by the cloud / web server; the invention realizes distributed control of the manufacturing system, so that each module has control Ability to improve system flexibility and reduce system response time.

Description

technical field [0001] The invention relates to an intelligent manufacturing system, in particular to a smart-RFID tag-based multi-unit intelligent manufacturing system containing robots. Background technique [0002] In Industry 4.0, it is proposed that the future intelligent manufacturing system should realize the paradigm shift from centralized control to distributed enhanced control, so as to establish a highly flexible personalized and digital production mode. [0003] Existing manufacturing systems are mainly divided into centralized control and distributed control, the main features of which are: [0004] 1) Centralized control is the control method adopted by most manufacturing systems at present. In the centralized control system, all production process data are uniformly stored on the background database server, the decision-making module of the manufacturing system is located at the top of the entire control system, and all control instructions in the production ...

AI Technical Summary

Problems solved by technology

The manufacturing units in these systems can make some simple decisions, but the whole system still needs a central control unit to manage and coordinate

In the distributed control, the unit decision-making rules are stipulated in advance, which lacks flexibility. In addition, the workpiece does not participate in the decision-making process. Therefore, to a certain extent, the current distributed control only realizes the decentralization of some control functions, and does not realize intelligence.
