Download or read book Monitoring Real Time Pavement Conditions Using an RFID Wireless Sensing Network written by Brandon D. Malaguti and published by . This book was released on 2015 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: States deal with bellow freezing weather causing roads and the ground below to freeze. When the ground begins to thaw, ice melts, leaving the ground under the roads softer. Large trucks carring heavy loads can cause permanent damage to roads when the roads are in a soft state. For this reason, a seasonal load restriction (SLR) policy is implemented to restrict truck loads during road thaw period. Consequently, SLR imposition results in a lack of profit from trucking and related industry. Currently, no cheap real-time method exists for road monitoring to allow trucks to change loads based on real-time circumstances. The proposed solution to this problem is to implement an affordable system for monitoring road temperatures and moisture using radio frequency identification (RFID) sensors. To successfully place and remove SLRs, the RFID sensors need to detect the current condition of the pavement and relay the condition to a collector, or RFID reader. The current condition of the pavement is measured using external temperature and moisture sensors. An onboard microcontroller unit (MCU) gathers the measured readings and wirelessly transmits the readings to a RFID reader above the surface of the road. Collected data is used by the Sate Department of Transportation (DOT) to properly decide the real time road conditions on a daily or hourly basis, effectively allowing the DOT to place or remove restrictions as necessary.

This book was released on 2011 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro-electromechanical systems (MEMS) provide vast improvements over existing sensing methods in the context of structural health monitoring (SHM) of highway infrastructure systems, including improved system reliability, improved longevity and enhanced system performance, improved safety against natural hazards and vibrations, and a reduction in life cycle cost in both operating and maintaining the infrastructure. Advancements in MEMS technology and wireless sensor networks provide opportunities for long-term, continuous, real-time structural health monitoring of pavements and bridges at low cost within the context of sustainable infrastructure systems. The primary objective of this research was to investigate the use of MEMS in highway structures for health monitoring purposes. This study focused on investigating the use of MEMS and their potential applications in concrete through a comprehensive literature review, a vendor survey, and a laboratory study, as well as a small-scale field study. Based on the comprehensive literature review and vendor survey, the latest information available on off-the-shelf MEMS devices, as well as research prototypes, for bridge, pavement, and traffic applications were synthesized. A commercially-available wireless concrete monitoring system based on radio-frequency identification (RFID) technology and off-the-shelf temperature and humidity sensors were tested under controlled laboratory and field conditions. The test results validated the ability of the RFID wireless concrete monitoring system in accurately measuring the temperature both inside the laboratory and in the field under severe weather conditions. In consultation with the project technical advisory committee (TAC), the most relevant MEMS-based transportation infrastructure research applications to explore in the future were also highlighted and summarized.

Download or read book Use of radio frequency identification tags in pavements written by Charles Warren Schwartz and published by . This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency identification (RFID) technology is widely used for inventory control, tool and material tracking, and other similar applications where line-of-sight optical bar codes are inconvenient or impractical. Several applications of RFID technology to pavements are evaluated in this report: tracking of placement of truckloads of hot mix asphalt (HMA) within the pavement, tracking of placement of truckloads of Portland cement concrete (PCC) within the pavement, real-time measurement of pavement temperature versus depth and time during intelligent compaction, and early detection of reflection cracking in overlays. RFID tracking of HMA placement was the most successful application and the one with potential for immediate commercial implementation. RFID tracking of PCC placement was unsuccessful, at least with the RFID systems evaluated in this study; the high dielectric constant of the hydrated cement paste severely attenuates the RFID signals. Real-time measurement of pavement temperatures with depth and time during intelligent compaction shows promise but further work is required to develop reader software/hardware and RFID tags with more reliable and faster response rates. Laboratory and limited field evaluation of an RFID-based sensor for early detection of reflection cracks in HMA overlays also shows promise, but additional development work and field trials are required. Guidelines for integration of material property data from construction and pavement performance data during service via RFID-assisted geolocation are also provided. The necessary steps required to integrate RFID-tagged material property and pavement management data are outlined in generic terms. Implementation details will depend on the materials and pavement systems used by each individual agency.

Download or read book Increasing Coverage and Improving Efficiency for Radio frequency Identification Systems and Wireless Sensor Networks written by Li Chen and published by . This book was released on 2015 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Radio-frequency identification (RFID), which uses radio-frequency electromagnetic fields to transfer data between an RFID reader and RFID tags in order to identify and track objects, has been widely deployed in recent years. RFID systems have the advantages of low cost, easy deployment and high design flexibility, and hence are used for access control, commercial tracking, toll collection and asset management. Compared to other identification methods such as bar codes and QR codes, RFID tags can be accessed without a line of sight, which increases the flexibility of ID tracking. One of the key limitations for RFID technology is coverage. An RFID system with better coverage can access more tags in a larger area with fewer RFID readers, which leads to lower cost, less access delay and higher tag access efficiency. My research begins with an investigation of the coverage problem for passive RFID tags. Due to the limitations of the transmission power, the coverage is limited. I developed and implemented a range extension approach for passive RFID tags using devices called edge devices (ZigBee-based, battery-powered, low-power readers). With the help of edge devices, the coverage of a single RFID reader can be doubled. Also, multiple edge devices can work cooperatively to further extend the coverage area. Another challenge in RFID system design is the MAC (Media Access Control) protocol. Due to some hardware limitations, most RFID systems are designed to use a contention based MAC protocol, which leads to high collisions, low fairness and low scalability. I proposed a token based RFID MAC protocol called Token-MAC to address these issues. Token-MAC can achieve a higher tag rate than contention based protocols. Also, Token-MAC can provide higher fairness performance, and it increases the scalability of the RFID system as well. I implemented the Token-MAC protocol in a programable RFID tag and evaluated the performance of Token-MAC. I also compared the performance of Token-MAC with a TDMA approach and the standard RFID protocol called C1G2 in experiments and through simulations. As passive RFID tags can be powered by an electromagnetic field, it is possible to use these devices to build a wake-up radio for Wireless Sensor Networks (WSNs). Passive wake-up radios can greatly increase the operational lifetime for a wireless sensor node by eliminating idle listening, when the node is awake but not transmitting or receiving data. However, due to the limited amount of energy harvested by an RFID tag, the limited wake-up range is a problem for passive wake-up radio sensor nodes. Most passive wake-up radio receivers can only work with a wake-up distance much shorter than the communication range. In this thesis, I present a passive wake-up radio design for Wireless Sensor Networks with extended wake-up range. This wake-up radio utilizes a high efficiency power harvesting receiver, a low power wake-up trigger circuit, and a wireless sensor node to build a passive wake-up sensor node called a REACH-Mote. Furthermore, due to the high efficiency power harvesting receiver and the compact RFID transmitter, it is possible to build a sensor node that operates using the energy obtained from the power harvester rather than from a battery and utilizes the harvested energy to transmit energy to nodes further away, waking up a second level of nodes. This potential network topology may lead to a new design in wireless sensor networks. In summary, I have developed 1) an RFID range extension method using edge devices that improves the coverage of RFID systems; 2) Token-MAC, an RFID MAC protocol that improves the performance of the RFID system; 3) passive wake-up radio sensor nodes called REACH-Mote and REACH2-Mote designed for wireless sensor networks; and 4) a multi-hop passive radio wake-up sensor node. These designs improve the performance of RFID systems and wireless sensor networks, enhancing the network stability, throughput and lifetime and enabling new applications of RFID systems and wireless sensor networks"--Pages v-vii.

Available in PDF, EPUB and Kindle. Book excerpt: Apress is proud to announce that Rethinking the Internet of Things was a 2014 Jolt Award Finalist, the highest honor for a programming book. And the amazing part is that there is no code in the book. Over the next decade, most devices connected to the Internet will not be used by people in the familiar way that personal computers, tablets and smart phones are. Billions of interconnected devices will be monitoring the environment, transportation systems, factories, farms, forests, utilities, soil and weather conditions, oceans and resources. Many of these sensors and actuators will be networked into autonomous sets, with much of the information being exchanged machine-to-machine directly and without human involvement. Machine-to-machine communications are typically terse. Most sensors and actuators will report or act upon small pieces of information - "chirps". Burdening these devices with current network protocol stacks is inefficient, unnecessary and unduly increases their cost of ownership. This must change. The architecture of the Internet of Things must evolve now by incorporating simpler protocols toward at the edges of the network, or remain forever inefficient. Rethinking the Internet of Things describes reasons why we must rethink current approaches to the Internet of Things. Appropriate architectures that will coexist with existing networking protocols are described in detail. An architecture comprised of integrator functions, propagator nodes, and end devices, along with their interactions, is explored.
