Unmanned Aerial Systems for Wildland and Forest Fires

Wildfires represent an important natural risk causing economic losses, human death and important environmental damage. In recent years, we witness an increase in fire intensity and frequency. Research has been conducted towards the development of dedicated solutions for wildland and forest fire assistance and fighting. Systems were proposed for the remote detection and tracking of fires. These systems have shown improvements in the area of efficient data collection and fire characterization within small scale environments. However, wildfires cover large areas making some of the proposed ground-based systems unsuitable for optimal coverage. To tackle this limitation, Unmanned Aerial Systems (UAS) were proposed. UAS have proven to be useful due to their maneuverability, allowing for the implementation of remote sensing, allocation strategies and task planning. They can provide a low-cost alternative for the prevention, detection and real-time support of firefighting. In this paper we review previous work related to the use of UAS in wildfires. Onboard sensor instruments, fire perception algorithms and coordination strategies are considered. In addition, we present some of the recent frameworks proposing the use of both aerial vehicles and Unmanned Ground Vehicles (UV) for a more efficient wildland firefighting strategy at a larger scale.Comment: A recent published version of this paper is available at: https://doi.org/10.3390/drones501001

Robot-assisted smart firefighting and interdisciplinary perspectives

Urbanization and changes in modern infrastructure have introduced new challenges to current firefighting practices. The current manual operations and training including fire investigation, hazardous chemicals detection, fire and rescue are insufficient to protect the firefighter's safety and life. The firefighting and rescue functions of the existing equipment and apparatus and their dexterity are limited, particularly in the harsh firefighting environments. It is well-established that data and informatics are key factors for efficient and smart firefighting operation. This paper provides a review on the robot-assisted firefighting systems with interdisciplinary perspectives to identify the needs, requirements, challenges as well as future trends to facilitate smart and efficient operations. The needs and challenges of robot-assisted firefighting systems are firstly investigated and identified. Subsequently, prevailing firefighting robotic platforms in literature as well as in practices are elaborately scrutinized and discussed, followed by investigation of localization and navigation support methods. Finally, conclusions and future trends outlook are provided

Firefighting Remote Exploration Device II

The need for “smart” recovery for disasters is at the forefront. Firefighters operating in indoor firegrounds are put at risk by the constantly changing environment. The use of robotics in firefighting can assist firefighters by informing them about different aspects of the fireground, such as the structural layout and temperature distribution. Taking inspiration from a design devised by a previous WPI Major Qualifying Project, our team prototyped a heat, water, and impact-resistant robot capable of navigating around obstacles in the fireground and returning relevant real-time data

Design principles of integrated information platform for emergency responses: The case of 2008 Beijing Olympic Games

This paper investigates the challenges faced in designing an integrated information platform for emergency response management and uses the Beijing Olympic Games as a case study. The research methods are grounded in action research, participatory design, and situation-awareness oriented design. The completion of a more than two-year industrial secondment and six-month field studies ensured that a full understanding of user requirements had been obtained. A service-centered architecture was proposed to satisfy these user requirements. The proposed architecture consists mainly of information gathering, database management, and decision support services. The decision support services include situational overview, instant risk assessment, emergency response preplan, and disaster development prediction. Abstracting from the experience obtained while building this system, we outline a set of design principles in the general domain of information systems (IS) development for emergency management. These design principles form a contribution to the information systems literature because they provide guidance to developers who are aiming to support emergency response and the development of such systems that have not yet been adequately met by any existing types of IS. We are proud that the information platform developed was deployed in the real world and used in the 2008 Beijing Olympic Games. © 2012 INFORMS

Battery Management Systems for Firefighting Robots Using Simulation Modeling

The battery management systems for firefighting robots are intended to enable firefighting robots to increase operating time and to effectively extinguish a fire while managing the amount of water in a fire hose and cooperating sub-robots. To increase the operating time by managing the traction power of the firefighting robot, a novel automatic T-valve device and sub-robots were designed and added to fire hoses. The main goal of the battery management systems for firefighting robots is to lower the weight of the fire hose and to increase traction power by working with sub-robots. Whenever a firefighting robot wants to move to other spaces, the battery management systems will remove the water from fire hoses and draw the empty fire hoses by using sub-robots; thus, they are able to help the main firefighting robot to carry lighter hoses and to operate for a longer time. As a result, the battery management systems for firefighting robots enable the firefighting robot to successfully extinguish a fire for a longer time and to efficiently reach the desired destinations. The demonstration will be modeled by a computer simulation program, called AnyLogic®, which can model a fire and fire areas and apply the battery management systems to robots in each fire site

GUARDIANS final report

Emergencies in industrial warehouses are a major concern for firefghters. The large dimensions together with the development of dense smoke that drastically reduces visibility, represent major challenges. The Guardians robot swarm is designed to assist fire fighters in searching a large warehouse. In this report we discuss the technology developed for a swarm of robots searching and assisting fire fighters. We explain the swarming algorithms which provide the functionality by which the robots react to and follow humans while no communication is required. Next we discuss the wireless communication system, which is a so-called mobile ad-hoc network. The communication network provides also one of the means to locate the robots and humans. Thus the robot swarm is able to locate itself and provide guidance information to the humans. Together with the re ghters we explored how the robot swarm should feed information back to the human fire fighter. We have designed and experimented with interfaces for presenting swarm based information to human beings

Information systems architecture for fire emergency response

Purpose There has been a lack of meaningful information systems architecture, which comprehensively conceptualise the essential components and functionality of an information system for fire emergency response addressing needs of different job roles. This study proposes a comprehensive information systems architecture which would best support four of the key fire-fighter job roles. Design The study has built on the outcomes of two previous preliminary studies on information and human-computer interaction needs of core fire fighter job roles. Scenario based action research was conducted with fire fighters in a range of roles, to evaluate human computer interaction needs while using various technology platforms. Findings Several key themes were identified and led us to propose several layers of an integrated architecture, their composition and interactions. Research limitations The selected fire scenarios may not represent every type of fire expected in high risk built environments. Practical implications The current paper represents a shared discussion among end users, system architects and designers, to understand and improve essential components. It, therefore, provides a reference point for the development of an information system architecture for fire emergency response. Originality The proposed information system architecture is novel because it outlines specific architectural elements required to meet the specific situation awareness needs of four of the key firefighters job roles

A user centred design evaluation of the potential benefits of advanced wireless sensor networks for fire-in-tunnel emergency response

This study aimed to assess, from an end-user perspective, the potential role of reconfigurable wireless networks in responding to a fire-in-tunnel incident. The study was based on a multi-media, scenario-based simulation of an incident, and assessment of the benefits and drawbacks of the new technology by subject matter experts in relation to their operational goals, with particular emphasis on support for situation awareness. Advanced wireless networks were shown to have considerable potential for improving the effectiveness, efficiency and confidence of emergency responders at various phases in a fire-in-tunnel incident, due to access to more accurate, complete and reliable information. A key requirement was to ensure that new technologies provided the right information, not just more information, at the point of need
