RFID electronic tags on the production line use RFID technology to realize automatic control in the production line. RFID tags accurately record process information and process operation information.

RFID electronic tags on the production line, using RFID technology in the production line to achieve automation, and monitoring of products, enormously improve the speed and accuracy of production, improve work efficiency, and improve production methods and cost. RFID labels can easily and accurately record stages of production and process operation information to meet the requirements of flexible production. 

  一、 Analysis of the demand for RFID in the manufacturing industry

The manufacturing production line loses massive materials almost every month, and the production results and expectations affect the delivery from time to time, and the production line often causes various errors due to human reasons. The RFID label  nestle up to the production material or product, which can automatically record the quantity, specifications, quality, time, responsible person, and other production information of the product, instead of the traditional manual record; The production supervisor reads the product information at any time through the reader; Other relevant personnel can grasp the production status and adjust the production arrangement according to the situation; Respectively, the procurement, production, and storage information are consistent and real-time monitoring; The system will automatically record the storage information and track the location in real-time.

  In industry, programmers use RFID technology to give an identification number (ID),  the component‘s name in the information network.Through RFID technology, the production status and inventory situation are mapped to the information network, then registered in the field center database, and finally transmitted to the information system. In the transmission to the information system.RFID technology's application to production line monitoring can realize automatic control and detection, saving costs. RFID tags can uniquely identify every 1 product. Through the application to record the raw materials and sources of each product, production line location, production process, inventory status, and other information. It provides an available basis for enterprises to preferable manage and adjusts inventory.

  二、RFID in the manufacturing industry application characteristics

  2.1 Data is shared in real time

  In the production process of manufacturing enterprises, it is very substantial for the production line to feedback on information in a timely and accurate manner. In the past, it was only possible to manually record faults while producing, and after completing the production, the statistical summary of this information from each process was time-consuming and laborious, and sometimes it could not be done very accurately. In each process of the production line to install RFID reading equipment, and in the product or pallet placed on the RFID tags can be repeatedly read and written. In this way, when the product is past these nodes, RFID read-write equipment can read the product or pallet tag information, and with this real-time feedback to the background of the management system, the manager can understand the production line work promptly.

  2.2 Standardized production control

  RFID systems provide a constantly updated stream of real-time data that complements manufacturing execution systems. The information provided by RFID can be used to ensure the correct use of machinery, equipment, tools, parts, etc, thus enabling paperless information transfer and reducing downtime. Further, as raw materials, parts, and assemblies pass through the line, the production process can be controlled, modified, or even reorganized in real-time to ensure reliability and high quality.

  2.3 Quality tracking and tracing

  In production lines where RFID systems are implemented, product quality is detected by test positions distributed in several locations.  At the end of production or before the acceptance of the product it must be possible to express its quality clearly with all the previously collected data of the work piece. This can be easily gone using RFID tags since the quality data obtained throughout the production process already travels down the line with the product.

   3 RFID in the production line application principle

  The current bar code based production management system enables various quality analysis and control to be easily realized, while bar code technology has its advantages and obvious disadvantages, such as easy to be contaminated, easy to be folded, scanning distance is close, etc., and batch reading efficiency is not high enough to meet the needs of fast and efficient.The use of RFID tags, bar codes, and sensors to collect real-time data from the production line site, and read the data through the network (wired or wireless) to the upper device (controller or computer). However, to manage the loose sensors will need a new, can automatically discover and organize the network of management mechanisms. The adopted method is to deploy RFID reader, and at the same time establish the reader network connection, solve the reader network planning, optimization and control problem. The RFID tag on the item, cooperate with the RFID read-write that connects into the network, each time recognition means a tracking of the item.
