Tracking Components and Maintenance History within a Facility Utilizing Radio Frequency Identification Technology

Limitations in data transfer between maintenance workers and a central facility management (FM) system result in lower data quality, longer service process times, and ineffective capturing of component maintenance history. Radio frequency identification (RFID) technology provides an opportunity to meet the current needs for uniquely identifying facility components, storing some maintenance history information on the component, and accessing this information on-demand within a facility. There have not been any research studies that tested the performance of active ultrahigh frequency RFID technology on facility components during operations and maintenance phase repetitively over an extended period of time. The objectives of this study were to identify how RFID technology can improve current FM processes and to determine technological feasibility of using RFID within a facility repetitively on a daily basis. The writers tagged fire valves in a facility with RFID tags and conducted a longevity test for sixty consecutive days by simulating tag identification, data access, and entry in real-life conditions. The results demonstrate that current commercially available active RFID technology performs well in a building environment where metallic objects and different obstructions are present. The observed reading distances were approximately half of the reading range expected in open air provided that there are not any massive obstructions between the reader and the tag.     

Implementing Radio Frequency Identification in the Construction Process

This paper provides construction industry owners and contractors with information about enhancing their operations using radio frequency identification (RFID) technology. Radio frequency identification involves the use of tags, or transponders, that collect data and manage it in a portable, changeable database; communicate routing instructions and other control requirements to equipment; and can withstand harsh environments. A construction industry-RFID supplier workshop was held to disseminate information about this technology and to generate suitable application ideas for the industry. With the information gathered during the workshop, one application idea was selected and pilot tests conducted to learn more about RFID and its applicability to the material procurement process on a construction site. The pilot tests showed that RFID tags reduced the time required to download data into a company’s material tracking system and could “flag” an item so an entry was not repeated. When scanning the tags, sun glare was not a problem as compared to using bar code labels. Although further analysis is necessary, RFID did show promise of being a beneficial technology as it relates to the materials receiving process. A flowchart is provided to assist contractors and owners in selecting the appropriate RFID system.

Ubiquitous Sensor Network for Construction Material Monitoring

Timely acquisition of construction resource information is an essential task for construction engineers and managers. Due to the harsh and dynamic construction environment, it is not easy to acquire construction information in real time. This paper presents a radio frequency identification (RFID) and ZigBee (IEEE 802.15.4)-based system to manage materials on a busy construction site where a data communications system is not in place. RFID tags are attached to and used to identify various kinds of construction materials, and the ZigBee communication technology is used to wirelessly transfer this information. To confirm the viability of our system, the RFID and ZigBee technologies were assessed using an indoor experiment. Following this, a field experiment was then conducted. On a building construction site, a range of construction materials was identified using RFID tags and this information was transferred to an end user with the help of ZigBee multihop networking. The results of the field experiment showed an acceptable reading range and rate for the proposed system. Therefore, the integrated system with RFID and ZigBee modules demonstrated great potential for improving the existing management processes for construction resources on large and complex construction sites.

RFID transponder integration in metal surgical instruments produced by additive manufacturing

Abstract

Radio frequency identification (RFID) applications are becoming more and more important in logistics, especially for the purpose of tracking and managing items. Real time tracking of medical instruments during a surgical operation belongs to the state-of-the-art applications of this technology. The metallic environment in the operating room represents a big challenge, hampering the readability of the RFID tag. Currently, transponders are joined to metal instruments by bonding or clamping them inside a polymer shell, containing as little metal as possible. Assembling the tags is a time consuming process, which changes the usual shape of the instrument. It also represents a point of failure because of the possibility of losing the tag during the instrument’s life cycle. Selective laser melting (SLM) offers a way to integrate the entire RFID tag in a metallic instrument while keeping the original shape. Instrument manufacturing by SLM allows small wall thicknesses and a reduced temperature impact on the RFID tag during the building process. The production of trial components from IN718 nickel alloy is reported.
