Localization and asset tracking are key components of the Internet of Things or the fourth industrial revolution called “Industry 4.0”. Current systems using GPS signals cannot be used indoors. Alternative systems for indoor localization exist, but they cannot be battery power with tiny batteries over multiple years. To overcome these drawbacks we propose a new localization concept based on an ultra-low-power...
Security is one of the major challenges for Cyber-Physical Systems (CPS) design. Identifying flaws as early as possible in the CPS design saves time and money [6]; between 5× to 10× less expensive [7] than finding them during the detailed design stages. This paper makes a case for finding cybersecurity flaws as early as possible. Not only for the temporal and cost benefits, but more importantly, for...
Data analytics plays one of the key roles in building intelligent systems, which bring automation to the new level of safety, reliability and efficiency, at the same time lowering the perceived complexity for the user. In this paper, we present the goals of data analytics in manufacturing and illustrate several application scenarios we have successfully worked on at Reifenhäuser REICOFIL GmbH &...
Extensive use of machines, flexible/re-configurable manufacturing and transition towards the fully automated factories call for intelligent use of information recorded during the manufacturing process. Modern manufacturing processes produce Terabytes of information during different stages of the process e.g sensor measurements, machine readings etc, and the major contributor of these big data sets...
In this paper we present a Hardware-In-the-Loop setup for the simulation of complex mechatronic systems. The setup consists of two coupled brushless motors. One of them is the motor under test, which is used to design the control algorithm and to test the control software, while the other one simulates the device to be controlled. Libraries of mechanical and hydraulic components have been implemented...
Based on Kurzweil's “Law of Accelerating Returns” we generate predictions on global annual shipments of industrial robots and briefly discuss a few relevant trends.
Cyber-Physical Systems (CPSs) represent a new paradigm of future intelligent systems. They consist of loosely coupled subsystems which interact with mechanisms of Service-oriented Architecture (SoA). In this paper we try to open a new topic in industrial communications. This topic is focused on basic communication patterns within CPSs. Patterns are abstract and generic solutions for common problems...
In this paper, a Profibus-ZigBee communication using low cost gateway is presented. The gateway is implemented using an electronic circuit and an embedded device. In this way, the transfered data and the used syntax to establish the communication are presented. The proposed implementation can be used in monitoring and control through wireless industrial communication between commercial devices (for...
Product lifecycles are getting increasingly shorter, but the lifecycles of industrial automation systems remain stable. Since future requirements for the industrial automation systems made by the market are often unknown at the beginning of the planning process, industrial automation systems have to be adaptable at later times. In addition, the efforts of planning should be reduced continuously without...
A frequently denominated use case of Industrie 4.0 is plug-and-work. This use case not only requires the technical base to determine how and what information has to be exchanged during the startup of software and hardware components in the production environment, but also deals with very sensitive information which results in a high demand to secure these. In consequence, plug-and-work mechanisms...
In this work in progress paper, we formulate performance robust event-based control strategies with respect to uncertainties in operation processing times. The proposed policies are based on a time-optimal schedule of operation sequences. A logical operation model is used to specify relations between operations. The control policies generate conditions ensuring to maintain the execution order given...
Distributed Embedded Systems (DESs) typically have dependability and real-time requirements. Moreover, when they are deployed in dynamic environments, they must be flexible enough to adapt to changes in the operation requirements. The Fault Tolerance for Flexible Time-Triggered Ethernet (FT4FTT) project aims at providing a Switched-Ethernet architecture, based on the Flexible Time-Triggered communication...
In this paper we discuss the challenges that are faced when the state-of-the-art research results are transferred to a model-based tool chain for the industrial use. These challenges are often overlooked when the research results are implemented in an academic environment. In particular, we discuss various challenges regarding the implementation and integration of the response-time analysis for heterogeneous...
New demands, coming from the industry 4.0 concept of the near future production systems have to be fulfilled in the coming years. Seamless integration of current technologies with new ones is mandatory. The concept of Cyber-Physical Production Systems (CPPS) is the core of the new control and automation distributed systems. However, it is necessary to provide the global production system with integrated...
This paper is presenting the ongoing work toward a novel driving assistance system of a robotic wheelchair, for people paralyzed from down the neck. The user's head posture is tracked, to accordingly project a colored spot on the ground ahead, with a pan-tilt mounted laser. The laser dot on the ground represents a potential close range destination the operator wants to reach autonomously. The wheelchair...
Robot interaction with the environment is normally described as a mass-spring-damping impedance model and the estimation of such interaction impedance parameters requires the computation of the joint (or task) space velocity and acceleration. In many cases, the velocity and acceleration are computed by numerically computing the first and second derivatives of the sensed position signal. The numerical...
Nowadays, smart metering and energy management installations are becoming essential part of building automation systems (BASs). Field level integration in these kind of installations could provide new features in buildings energy monitoring and improve control quality in BASs. In this context an interoperability of BAS devices is very important. It could be achieved with standardized functional profiles...
