“…Thus, some optimal layout algorithms are established for the robust design of RFID systems. Huang and Chang proposed a layout model by taking the ellipse-like shape of an RFTD signal range [27] instead of the traditional 2D circle-like shape assumption [28,29]. The main goal of such algorithms is focused on using the least RFID readers to cover the entire manufacturing area in a shop floor with the least reader signal collision.…”

As a key advanced manufacturing technology in next generation manufacturing systems, radio frequency identification (RFID) technology is considered to be one of the most promising technological innovations with the potential to increase visibility and improve efficiency. Therefore, research about RFID and its applications are increasing by blasting with all kinds of RFID models in various fields, especially in manufacturing. By introducing RFID technology into the job-shop floor, this paper proposes a systematic RFID-driven graphical formalized deduction model (rfid-GFDM) for describing the time-sensitive state and position changes of work-in-progress (WIP) material flows and guiding where to deploy RFID devices and how to use them for collecting real-time on-site data. Four steps including RFID configuration based on the process flow model, state blocks model, automatic event generation, and extended event-driven model are proposed one by one to support the implementation of rfid-GFDM. The nature of RFID technology is revealed, too. A use case about a computer numerical control (CNC) milling system is studied, and it demonstrates the feasibility of the proposed model. Finally, the possibility of popularizing the model to other field is discussed, too. It is expected to establish a normative RFID modeling method that will facilitate the convenience of RFID applications in a broad scope.

“…In this section, we present a brief survey on known localization techniques which can be classified into two categories: 2D localization [5][6] and 3D localization methods [7] [8]. 2D localization consists of determining the position of objects scattered in a planar area where readers are deployed.…”

In last decade, indoor localization of target objects has been intensively studied. In particular, schemes that use RFID tags for precise localization of sensor nodes have received more interests. 3D localization based on RFID tags in indoor environments has not been enough studied. In this paper and at the attempt of contributing in this topic, we propose an approach based on MDS for 3D localization using active RFID tags in indoor environments. The considered system is a centralized scheme that involves a server, readers and tags. The propagation model used to estimate the received power considers the path loss and shadowing effects. To show the accuracy of the proposed scheme, a selection of numerical results is used.

“…As is shown in Fig. 24.1, ToA is the position tracing method by calculating absolute time from the terminal to the minimum 3 receivers [12,13] Lots of dispersed moving objects (receivers) are used for receiving the signal transmitted from signal source, in general, and the accurate position of receiver can be estimated by ToA or Time Difference of Arrival (TDoA). For the position calculation of ToA based receiver, the circles of uniform distance for the ToA are drawn, and the intersecting point of these circles is calculated by the following Formula (24.1).…”

Various kinds of wheelchairs have been developed to secure mobility of the aged and disabled people foe convenience of Activity of daily living (ADL). Accurate positioning technology is necessary to secure the mobility for realization of autonomous driving technology among the versatile wheelchair functions. In case of global positioning system (GPS), which is most widely used for the provision of positioning information, it is difficult to provide the accurate indoor positioning information. This paper has suggested active RFID system to overcome such shortcomings and to embody the indoor positioning technology. The error ratio has been checked out by the active RFID system implemented in the limited test space, after making compact and low-power active RFID module, measuring Time of Arrival (ToA), and estimating the positioning information using Received Signal Strength Indication (RSSI). It has been confirmed as of the estimation result of error ratio in the test space that accurate indoor positioning can be provided within about ±2 cm deviation. Continuing research will be necessary in order to provide accurate indoor positioning information of autonomous driving wheelchair.
