The Intelligent Space Modeled as a Cyber-Physical System
1-6.Views:427According to a general rule definition, the intelligent space (iSpace) is defined as a location (or space) provided with electronic sensor networks that enable the considered environment with intelligent behaviors. As a result, the considered space will be able to perceive stimulus around them and to understand events that happen its near surrounding. Cyber-physical systems (CPSs) are building blocks in Industry 4.0 that links digital technology and the physical environment in an industrial context. They combine intelligent physical objects and systems on a high level of functions integration. This paper emphasizes the main idea that intelligent spaces may be also modeled as complex cyber-physical systems, as well. This approach has been developed by discussing the theoretical basis of both the iSpaces and CPSs, respectively unfolding a short comparison between their basic behaviors. As a concrete example, the CPS model of a given iSpace framework is presented and discussed widely in the paper. This model has been experimented by using a Field Programmable Gate Array (FPGA) processor-based ready-to-use development systems and software technologies that handles reconfigurable hardware technology. The implementation proves that the developed CPS model is well feasible and expresses in all the main behaviors and functions of iSpaces. It is also mentioned that the actual stage of the technological development terms and scientific areas related to iSpaces and CPSs overlaps. In fact, this is not surprising at all by considering nowadays evidence that iSpaces are widely present and shared components in modern manufactory processes that are an inherent part of Industry 4.0 vision and reality.

Benefits of Cyber-Physical Systems Modeling and Simulation with LabView
1-6Views:340Cyber-physical systems (CPSs) as part of the Industry 4.0 strategy, represents one of the most challenging research topic for engineers. It’s well known that CPSs integrate at highest level digital technology (computation, control and networking) into physical objects. However, by incorporating various heterogeneous subsystems with different energy levels and functionalities, both analogue and digital signals management, as well as a large scale of communication and information technologies, their modeling and simulation becomes a difficult engineering task. In the past years a huge number of research papers has been dedicated to identify and develop modeling techniques and simulation toolkits being able to handle CPSs complexity. Following these trends, this paper is focused to research and evidence issues linked with the LabView graphically oriented programming technology utilization for CPSs modelling and simulation purposes. Both advantages and shortcomings of this very special technology are studied in order to design and implement a viable software framework being able to model and simulate various CPS structures. As a concrete example, a specific CPS configuration consist of six computer-based mechatronic systems that constitute a laboratory-prototype manufacturing plant has been chosen for LabView-based modeling and simulation. Various virtual instrument-type models of this setup has been conceived and proposed for real-time simulation. It has been concluded then that the application of LabView technology lead to interesting and useful results. The paper specially highlights the benefits and versatility of LabView utilization for complex CPSs modeling and simulation purposes.

Intelligent Buildings as Cyber-Physical Systems: a Reconfigurable Hardware Technology-based Approach
1-7.Views:708This paper discusses the idea to change the way to approach intelligent buildings (IBs) development and implementation by taking into account the last evolutions in cyber-physical systems (CPSs). Therefore, the main goal is to extend IBs design engineering with the constraints of systems in a CPS context. As well known, smart buildings are increasingly complex as they integrate many scientific areas and research topics, as well as a large scale of last-generation technologies. At the same time, the Internet has deeply transformed the way to manage information and services, respectively how information is transmitted and computed in cyberspace. The quick management and information processing inside cyber layer challenges the interaction with the physical world in a sense to develop IBs as smart distributed systems or CPSs. In addition to this, the papers emphasize the original idea of developing reconfigurable hardware technology-based (RHT-based) CPS architectures for IBs implementation purposes. The benefits of the RHT application in a CPS context for IBs are widely discussed and analyzed. The unfolded theoretical background has been supported by an implementation example using last generation software technologies. These experiments evidence the advantages and versatility of this challenging implementation paradigm of the latest digital technology, applied for current-state IBs development.

ROS OS Based Environment Mapping of Cyber Physical System Lab by Depth Sensor
1-6Views:520The 21st century is a century of Robotics and thus the appearance of robots in the industries made the “Industrial Revolution 4.0” in which we can control and analyse the system using HMI’s or wirelessly over network and it’s a great example of industry 4.0 component. Nowadays robots are very important part of industry’s processing unit as they have the tendency to work 24*7 thus increases the efficiency of processing and production unit.
In our project a depth sensor (Microsoft’s Xbox Kinect) is mounted on a mobile robot whose main task is to map our Cyber Physical System Lab in 3-Dimensional which uses a ROS OS software installed on linux machine.
The robot will use a Simultaneous localization and mapping (SLAM) process to map an environment while currently generating an estimate for the location of the Robot.
