  2. 1. Vision-based Human Detection from Mobile Machinery in Industrial Environments

    Author : Rafael Mosberger; Achim J. Lilienthal; Henrik Andreasson; Jürgen Gall; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Industrial Safety; Mobile Machinery; Human Detection; Computer Vision; Machine Learning; Infrared Vision; High-visibility Clothing; Reflective Markers; Datavetenskap; Computer Science;

    Abstract : The problem addressed in this thesis is the detection, localisation and tracking of human workers from mobile industrial machinery using a customised vision system developed at Örebro University. Coined the RefleX Vision System, its hardware configuration and computer vision algorithms were specifically designed for real-world industrial scenarios where workers are required to wear protective high-visibility garments with retro-reflective markers.

  4. 2. Condition Monitoring in Mobile Mining Machinery

    Author : Erik Jakobsson; Erik Frisk; Mattias Krysander; Olga Fink; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The global mining industry is currently facing a huge transition from manually operated individual vehicles, to autonomous vehicles being part of an industrial process-like environment. The change is driven by the never ending need for efficient, safe, and environmentally friendly operations. READ MORE

  5. 3. On Electrified Fluid Power Systems in Mobile Machinery

    Author : Samuel Kärnell; Liselott Ericson; Petter Krus; Rudolf Scheidl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; Electrification; Variable displacement; Pump-controlled systems;

    Abstract : High power density in combination with flexible power distribution possibilities and extreme robustness are reasons why fluid power has been the preferred technology in mobile machinery, such as excavators and cranes, since the mid-20th century. In principle, the machines have been powered by a combustion engine which powers a pump, with the output from the pump being distributed to different functions via valves. READ MORE

  6. 4. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

    Author : Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Abstract : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. READ MORE

  7. 5. Information Visualization Using Transparent Displays in Mobile Cranes and Excavators

    Author : Taufik Akbar Sitompul; Rikard Lindell; Björn Lisper; Philippe Palanque; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Operating heavy machinery, such as mobile cranes and excavators, is a complex task. While driving the machine, operators are also performing industrial tasks, e.g. lifting or digging, monitoring the machine’s status, and observing the surroundings. READ MORE
