RFID systems with distributed controllers

In order to maintain competitiveness, companies need to improve their efficiency while better responding to changes in market demand. This shift from production orientation to service and demand orientation also means better coordination between people, machines, and products, as well as providing more accurate information about the current material flow. Currently, the use of RFID has been launched       

 The solution for the production control system utilizes real-time data from the site.                 The company monitors the parameters of machines and equipment in its SCADA system, such as power, flow rate, or air pressure. The management of copper pipe production is even more difficult because they are the common result of multiple different processes. But the process after melting and casting is still standard. The product from the previous process becomes the raw material for the next machine, rather than a monotonous production line. Previously, workers had to manually transmit all production data, such as information about raw materials or process parameters, due to concerns. This is very time-consuming and laborious, and it is almost impossible to have real-time data.                          To simplify material management, an RFID solution is provided directly near the machine. This can be used to control the entire production process. This takes advantage of the fact that copper pipes are located on circular metal frames during the cold forming stage of the production process. The material information about the batch can be associated with the relevant material frame, and the RFID carrier can be easily fixed on the material frame        For this purpose, a sturdy shell carrier specially designed for installation on metal is used, which can remain fixed on the material frame even when it rotates at high speed. Specific shelf numbers are stored in the carrier and subsequently assigned to specific batches in the production management system. For this purpose, the production management system will access the database. The communication between the reader and the production management system is provided through the IO system, which also controls the distributed operation of RFID readers.                  RFID ultra-high frequency reading head        Install near each workstation. When recognizing, the read-write head does not need to be directly facing the carrier to read the number of the material frame, and the recognition distance is far. The connection with the production management system enables data exchange between the code carrier, read-write head, and higher-level production execution system (MES).                          When the copper tube is pulled out, the machine unfolds it from the metal frame and guides it through the reducing mold, then rewinds it at high speed onto another frame. The RFID system ensures that the material data of the copper tube can also be uniquely assigned when transmitted to the second shelf. For this purpose, the RFID reader reads the material frame number from the RFID carrier and transmits it to the production management system. This will allocate the material data of the copper tube to the appropriate material frame and record the process at the same time. In this way, RFID provides assistance in data transmission throughout the entire material flow.
