Enhanced Passive RFID Based Disaster Management for Coal Miners

Abstract

Abstract-Solutions exist to cater the various aspects of an emergency response in coal mines that are subjected to the quality and availability of relevant information often oblivious due to inevitable and unpredictable nature of disasters. The major challenge is to implement a scheme which is economically viable, reasonably accurate and modestly enforced with least maintenance. Inexpensive Passive RFID (Radio Frequency Identification) tags offer a simplistic yet elegant approach in cumulating pertinent data which primarily aids in potentially disastrous situations and also serves to increase productivity in mundane activity of the mine. This paper presents a novel concept of organizing and interpreting the cognition of identities employing passive RFID tag with an additional radio frequency energy harvesting module capable of delivering power upto -19 dBm in turn fostering the range and readability figures. The first step towards a palpable database to make dynamic evacuation plan a substantial reality is emphasized. A comparative study is shown between a normal RFID tag and the enhanced one, which exhibits promising results.

Virtual Reality Evacuation Experiments on Way-Finding Systems for the Future Circular Collider

“…A further innovative wayfinding installation investigated here that could potentially be implemented in such type of facility is a robot on a monorail which includes an intelligent device to locate evacuees (e.g. such devices may be based on radiofrequency identification (RFID) sensors [19,20] or thermal cameras [21]) and then provide way-guidance information. Those technologies may already be implemented in particle accelera-tor tunnel facilities for other scopes (e.g.…”

“…or infrastructures which requires a higher level of safety (e.g. mines [19]), thus their use for safe evacuation is feasible.…”

Antenna with a reactive impedance substrate for mine rescue applications

“…Once the search has commenced, the rescuers can employ a system that actively communicate with the RFID systems on the lost or trapped miners, thereby allowing the rescuer to ascertain where the miners are relative to their own position. A possible solution would include a directional antenna that can be worn by the rescuer while they are looking for the trapped miners …”

“…A possible solution would include a directional antenna that can be worn by the rescuer while they are looking for the trapped miners. 1 Antenna miniaturization has allowed for the realization of antennas small enough to be considered wearable at increasingly lower frequencies, the possible applications for body area networks (BANs) have increased. BANs, which can allow for wireless communication between different subsystems located on a single human, as well as allowing wireless intrapersonal links between a BAN and remote systems, can now be implemented over an ever-increasing range of frequencies.…”

Efficient Garbage Disposal Management in Metropolitan Cities Using VANETs

“…The WSN is built of nodes from a few to several hundreds or even thousands, where each node is connected to one or several sensors. Each such sensor network node typically has several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting, [4], [5].…”
