RFID technology in industrial production lines
2022-10-24
Industrial production line requirements
Manufacturing production line almost every month to lose a lot of materials, and production results and expectations because there is an error and affect the delivery of the situation occurs from time to time, the production line is also often caused by human reasons caused by various errors. RFID tags attached to production materials or products, can automatically record the product quantity, specifications, quality, time, responsible person and other production information, instead of the traditional manual records; production supervisor through the read-write read product information at any time; other relevant personnel can timely grasp the production status and according to the situation to adjust production arrangements; procurement, production, warehousing information consistent and can be monitored in real time; materials and products leaving the warehouse The system will automatically record the in/out information before the materials and products leave the warehouse, and can track the location of the items in real time.
The program analysis
1, the concept of RFID intelligent technology
RFID (Radio Frequency Idenlification) is the radio frequency identification, commonly known as electronic tags, wireless radio frequency identification belongs to the short-range wireless communication technology. It is composed of RFID tags, readers and antennas, of which RFID tags are composed of antennas and chips, each chip has a corresponding recognition barcode, containing information that can be set by itself. The specific working principle is through the radio frequency signal to the target and the object for automatic identification and then obtain the relevant data, for some high-speed objects also have a high recognition effect and also be able to identify multiple hoops at the same time, the operation is convenient and fast application prospects are wide, at present in the creation of library management, supply chain automatic management, anti-counterfeiting identification, medical and automated production and other fields are involved in RFID intelligent The application of technology.
RFlD intelligent technology does not need to establish any mechanical equipment or optical contact between the identification target or object, that is, the whole process without human intervention, in some environment is relatively harsh not suitable for manual operation has a great advantage. According to this, RFID intelligent technology is gradually being widely used in the field of industrial automation, in the field of manufacturing and assembly can use RFID to achieve visual management of automated production lines and control of the production process.
2、Hardware selection
RFID equipment hardware selection, need to meet several necessary conditions.
1) Read-write installation as simple as possible.
2) Read-write industrial grade IP56 or above.
3) the site distance can be controlled, no misreading leakage situation, the tag collection rate of 100%.
4) can perfectly match the modbus communication protocol of industrial PLC.
For the above several production hard demand, our company proposes to use our self-developed industrial reader VI-IR600, waterproof, tamper-proof, dustproof, tamper-proof, shockproof. And industrial production line perfect fit.
The product shape adopts industrial design, sturdy and durable, in line with the harsh industrial production line environment (electromagnetic interference, dust, waterproof, tamper-proof, resistant to the highest -25 ° - 70 ° environment, vibration, noise) waterproof to IP67 requirements, shockproof standard: Vibration EN 60 068-2-6; lightning protection standard: Shock EN 60 068-2-27.
RF using independent intellectual property development chip, with high-performance tag recognition algorithm, performance comparable to imported products in Europe and the United States.
Support Modbus protocol, ModbusRTU and PROFINET protocol.
Working frequency 865~868MHZ, 902~928MHZ (can be adjusted according to the requirements of different countries or regions).
Super long reading distance, reading distance can reach 0mm~7500mm, writing distance 0mm~4000mm.
Support automatic card reading, command card reading, trigger card reading and other working modes.
Read the card beep and LED status indication; support firmware upgrade through the communication interface.
Products through the domestic and foreign authoritative testing agencies certified FCC, CE, etc.
Bottom cover design mounting bracket, convenient for industrial production line environment layout reader installation.
Support RS232 serial port, network port upgrade firmware, WIFI upgrade firmware. Is the ideal choice for industrial production line manufacturing.
The advantages of using RFID technology
A cost / benefit analysis report is very important to the successful implementation of RFID. The current implementation of RFID technology still exists such as cost, technology, standards and other aspects of the problem, some companies for the implementation of RFID technology is still in a wait-and-see attitude; but RFID technology can bring great benefits, including indirect benefits, such as improved customer satisfaction. These should be included in the report and analyzed on a case-by-case basis for return on investment.
Prior to implementation, the business requirements for deploying an RFID system should be defined and these requirements analyzed. It is also important to take into account all the factors involved in developing and deploying an RFID system, and to make a comprehensive plan. Once the planning is done, it is important to put it in the hands of those who have the real power to make decisions to ensure that they will be followed through.
The RFID implementation plan is divided into four feasible phases to achieve a smooth and slow transition. These are: start-up, testing and validation, pilot implementation, and real implementation. For large manufacturing enterprises, the key is how to use RFID information to achieve information integration with existing systems, optimize internal business processes, and improve the core competitiveness of enterprises. Although the real implementation of RFID is not easy, sometimes it requires reorganization of existing production lines, training of highly qualified staff, regular inspection of software systems and hardware equipment, etc.. However, for companies with a strong sense of modern business management. The application of RFID technology will bring great benefits.
