Design of Anti-Metallic RFID for Applications in Smart Manufacturing

Anti-metallic passive RFID tags play a key role in manufacturing automation systems adopting RFID techniques, such as manufacturing tool management, logistics and process control. A novel long range passive anti-metallic RFID tag fabrication method is proposed in this chapter, in which a multi-strip High Impendence Surface (HIS) with a feeding loop is designed as the antenna radiator. Firstly, the bandwidth enhancement methods for passive RFID tags based on micro strips are discussed. Then, a RFID tag design based on multi-strip antenna is proposed and its radiation efficiency is analyzed. After that, some key parameters of the RFID antenna proposed are optimized from the viewpoint of radiation efficiency and impedance match performance. Targeted for manufacturing plants with heavy metallic interfering, the proposed RFID tag can significantly enhance the radiation efficiency to improve the reading range as well as the bandwidth. Finally, some RFID tag prototypes are fabricated and tested to verify their performance and applicability against metallic environment, and the experimental results show that these fabricated RFID tags have outstanding reading performance and can be widely used in manufacturing plant full of heave metallic interfering.

Passive Rfid

RFID is a short distance communication system which comprises of a RFID tag, a RFID reader and a personal computer with desired software that can maintain the related information. These RFID tags can be of active or passive types. This paper focuses on design, simulation and fabrication of passive ultra-high frequency RFID tag (microchip and an antenna) which resonates at the frequency 866 MHz in the Industrial Scientific Medical Band. The nested H-slot inverted-F microstrip antenna structure is used for the design of passive RFID tag. It examines the specific tag geometry and its characteristics to optimize the PIFA antenna and in turn RFID tag’s performance.

This paper presents methods of localization of mobile systems using recent Radio Frequency Identification (RFID) technology. We consider an indoor environment where RFID tags are implanted along the wall or in objects in the room. If the absolute position and orientation of a tag are read by an RF reader, a mobile system can estimate its location using the information saved in the tags. A reader-tag model is obtained through experiments in order to derive relative positions and orientations between an antenna and an RFID tag. To estimate the location, we propose two estimation methods. One uses a single RFID tag and the other uses multi-RFID tags. Experimental results show that the proposed methods can provide good performance for mobile system localization in an indoor environment.

As human race or human society is growing, the wildlife animals or wild animals are in danger. But as per natures rule, every living creature on this earth is important and has important role ecosystem. The domestic animals get misplaced sometimes and finding them is a tedious task. RFID and sensors have been deployed to detect and identify missing animals by affixing them with cheap passive RFID tag and monitoring them with RFID readers. So the proposed system will help us to detect and find the missing animals using RUN protocol. RUN protocol uses slotted aloha for communication between tags and readers. It execute multiple frame for different seeds to reduce the effect of unexpected tags and also it reduces the time of missing tag detection and identification. To obtain optimal frame sizes and minimum no of times aloha frames should be executed to mitigate the effect of unexpected tags. RUN protocol works with multiple readers with overlapping region. It identifies 100% missing tags in the presence of unexpected tags where as other protocol only identifies 60% of missing tags.

The transition from traditional to truly smart dynamically adaptable manufacturing demands the adoption of a high degree of autonomy within automation systems, with resultant changes in the role of the human, in both the manufacturing and logistics functions within the factory. In the context of smart manufacturing, this paper describes research towards the realization of adaptable autonomous automation systems from both the control and information perspectives. Key facets of the approach taken at WMG are described in relation to human–machine interaction, autonomous approaches to assembly and intra-logistics, integration and dynamic system-wide optimization. The progression from simple distributed behavioural components towards autonomous functional entities is described. Effective systems integration and the importance of interoperability in the realization of more distributed and autonomous automation systems are discussed, so that operational information can propagate seamlessly, eliminating the traditional boundary between operational technology and information technology systems, and as an enabler for global knowledge collection, analysis and optimization. This article is part of the theme issue ‘Towards symbiotic autonomous systems'.
