RFID radio frequency identification is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals. Short-range RFID without human intervention, not afraid of oil stains, dust pollution and other harsh environments, can be used in such environments to replace the bar code, such as applications in factories on the assembly line to track objects. Long distance rfid products are mostly used in transportation, recognition distance can reach tens of meters, such as automatic toll collection or identification of vehicle identity. This article discusses the specific application of rfid production line management automatic identification.
RFID application in the retail industry is the benefit of the use of RFID barcode technology makes tens of thousands of types of goods, price, origin, batch, shelves, inventory and other information transparent.This article will explore the specific application scenarios of RFID in production line, technical advantages and future development trends, revealing how it injects new kinetic energy for intelligent manufacturing.
1.RFlD-Based Production Line Management Applications
In order to produce better quality products while reducing production costs. And to meet the requirements of ISO 9000, manufacturers are more carefully tracking product information and spray volume control with lJ process, which requires manufacturers to implement RFID.
RFID is moving into the heart of the manufacturing process. By progressively adopting RFID auto-ID technology at the factory floor level, manufacturers have direct and uninterrupted access to information captured from RFID and linked to existing, validated and industrially-enhanced control system infrastructures, coordinating with RFID-enabled supply chains to send accurate, reliable streams of real-time information, without the need to update existing Manufacturing Execution Systems (MES) and Manufacturing Information Systems (MIS), thus eliminating the need to update existing MES and MIS systems to send accurate, reliable streams of real-time information. The RFID-enabled control system infrastructure coordinates with the RFID-enabled supply chain to send accurate, reliable, real-time information flows without the need to update existing MES and MIS systems, thereby creating added value, increased productivity and significant investment savings.
2. Information management real-time effectiveness of processing
For manufacturers, timely and accurate feedback from the production line is very important, in the past can only wait until after the end of production to settle the statistics of this information, time-consuming and laborious, sometimes inevitably human error.
If the production line at each node to install RFID reading equipment, and in the product or tray placed on the repeated reading and writing of RFID tags. In this way, when these products or trays through these nodes, RFID read-write equipment can be read to the products or trays on the tag within the information, and these systems real-time feedback to the back-office management system, the manufacturer will be able to easily and timely understanding of the production line’s detailed working conditions. And then RFID and existing manufacturing information systems such as MES, ERP, CRM and IDM combined, you can establish a more powerful information chain, in order to transmit accurate data at the exact time in a timely manner, thereby enhancing productivity, improve asset utilization and a higher level of quality control.
3.Manufacturing management process applications
As RFID can provide constantly updated real-time modern business data flow, combined with manufacturing execution systems, RFID provides this information to ensure how to correctly use the labor force, machines, tools and components. With this timely and accurate information management, paperless, contract manufacturing becomes possible, and production line downtime can be greatly reduced and production efficiency increased.
Such as a batch or even several batches of contract products, need to use the same production line for plus production, but only in some parts slightly different. Previous production methods, can only be used to first produce the same type of product, the production line will be shut down, after adjusting the production of another model of the product, which caused losses.
Through the implementation of RFID system, different models of products can be coded and written into RFID tags. When different models of products enter the processing point, RFID read-write equipment by reading the information in the RFID UHF tags, so that the processing equipment to confirm the processing of which model of products. If there is an automatic sorting conveyor, through the recognition of RFID tags, it can easily complete the classification of products, so that the products will be sent to the correct production line.
4.production logistics management in the RFID
Manufacturing industry contains both purchasing and sales, but also contains the low-value materials into high-value-added products manufacturing. Quick response (QuickResponse) and agile (Agility) is a key factor in the success of the manufacturing industry. And production logistics is the core of the entire logistics of the manufacturing industry. Production logistics and production process synchronization, from the purchase of raw materials until the finished product sent until the whole process of logistics activities. Raw materials, semi-finished products, etc. in accordance with the process flow in the various processing points between the non-stop movement, transfer, the formation of the production logistics. It is the manufacturing of products for the production of enterprise-specific activities, if the production is interrupted, the production logistics will also be interrupted, and vice versa.
With the help of RFID radio frequency identification technology, raw materials, components, semi-finished products and in-process electronic tags on the production planning management personnel can quickly locate and understand the depletion of raw materials. This will greatly improve the efficiency and quality of production; at the same time, RFID radio frequency identification technology is also able to product information collection, processing, to help production personnel to easily grasp the operation of the entire production line and the realization of the production of products to further accelerate the progress. Due to the read-write characteristics of RFID, it can provide a constantly updated real-time data stream. Complementing manufacturing execution systems, RFID provides information that can be used to ensure the correct use of labor, machines, tools and components. This enables paperless production and reduced downtime, facilitating smooth production logistics.
Further, RFID can be combined with existing manufacturing information systems such as ERP, CRM, etc. to create a more robust information chain and enable the timely delivery of accurate data at the exact time, which can improve asset utilization, enhance productivity, perform a variety of online measurements, and support quality control.
5.Conducting Accurate Information Tracking
To comply with FDA quality specifications, manufacturing companies of consumer packaged goods, food, and beverages are prompted to be able to accurately track and trace product information throughout their supply chains. Today, due to negligence at some point in the process, products with quality problems enter the market. These questionable quality issues can lead to a threat to the life of the consumer in the worst case scenario. As a result, it is not uncommon to hear of factory recalls of products. With the help of RFID systems, there is accurate and timely information feedback, enabling manufacturers to quickly check the production date of the product in question, the contract number, the source of raw materials, the production process, and can even be as precise as needed to the information of a particular product in question. In the manufacturing industry in the product (pallet) identification, intelligent conveyor path selection, date and production time verification, automatic guided vehicles, batch production of formulas and other aspects of the application of RFID systems, real-time information management can be achieved, flexible manufacturing management, accurate tracking and tracing of these goals, and to improve the level of automated production, production efficiency, so that the production management is more flexible, and ultimately, the manufacturer benefits! The application of RFID system can achieve real-time information management, flexible manufacturing management, accurate tracking and tracing of these goals, and improve the level of automated production, production efficiency, production management more flexible, and ultimately benefit manufacturers.
6. Huge Benefit Prospects
But along with the huge benefits will come the huge challenges of implementing this new technology. Therefore, for large manufacturing companies, in the implementation of RFID radio frequency identification technology before, must do a good job of pre-planning for the successful implementation of RFID systems in the future to lay a solid foundation.
6.1 Cost / benefit analysis.
A cost / benefit analysis report on the successful implementation of RFID is very important. The current implementation of RFID radio frequency identification technology there are such as cost, technology, standards and other aspects of the problem, some companies for the implementation of RFID radio frequency identification technology is still in a wait-and-see attitude; but RFID radio frequency identification technology can bring great benefits, including indirect benefits, such as improving customer satisfaction. These should be included in the report and analyze the return on investment according to the actual situation.
6.2 Application system analysis.
Before implementation, to clarify the deployment of RFID systems in the business needs and analyze these needs. At the same time, we must also give full consideration to the deployment of RFID systems in the development of a variety of factors, co-ordination and regulation. After the planning is done, the planning to be handed over to the hands of the people who have the right to really decide, in order to ensure that they will be really carried out.
6.3 The development of the implementation plan.
Combined with the application system analysis report, the development of RFID implementation plan. RFID project implementation, generally divided into four feasible phases of the plan, and gradually achieve a smooth and slow transition. That is: starting, testing and verification, pilot implementation and the real implementation of the four stages. For large manufacturing enterprises, the key is how to use RFID information, to achieve information integration with existing enterprise systems, optimize internal business processes, and improve the core competitiveness of enterprises. Although the real implementation of RFID is not easy, sometimes need to reorganize existing production lines, high-quality staff training, software systems and hardware equipment for regular testing and so on. However, for very modern enterprise management awareness of the enterprise, the application of RFID radio frequency identification technology will bring great benefits.
