Abstract [en]

Industry 4.0 is advancing the use of Internet of Things (IoT) devices in industrial applications, which enablesefficient device-to-device (D2D) communication. However, these devices are often heterogeneous in nature, i.e. from different manufacturers, use different protocols, etc. and adds requirements such as security, interoperability, etc.To address these requirements, the Service-Oriented Architecture-Based (SOA) Arrowhead Framework was previously proposed using the concept of local clouds. These local clouds provide a set of mandatory and support core systems to enable industrial automation applications. One of these mandatory core systems is an Authentication, Authorisationand Accounting (AAA) system, which is used to authenticate and provide access control to the devices in a local cloud. In an industrial context, with multiple stakeholders, the AAA mustsupport fine-grain access control. For example, in a distributed control loop, a controller should only have read access to its sensor such as a flow meter and write access to its actuator, such as a valve. The controller should not have access to anyother information besides what is needed to implement the desired functionality. In this work, an NGAC-based AAA solution to achieve fine-grain service level access control between IoT devices has been proposed and implemented. The solution is presented using a district heating use case.

Abstract [en]

The 4th Generation of District Heating (4GDH) is a complex agglomeration of heat providers, distributors, and consumers that must be automatically, continuously managed and coordinated. It is a complex system of systems; a definition which we align to Maier’s architecting principles for systems-of-systems as collaborative systems. Wrapped in the idea of system of systems is the reality that the 4GDH systems’ descriptions and specifications are not currently all known. Nonetheless, the transition into the 4GDH is actual. We propose the use of two frameworks to secure a smooth metamorphosis and assure systems’ operation, maintenance, and evolution. The two frameworks are the Arrowhead Framework and the OPTi Framework. The first one enables system integration through Service Oriented Architecture (SOA) and the second one offers the overall system optimization with respect to all stakeholders. This paper uses the Model Based Systems Engineering (MBSE) tool SysML to model a district heating complex’s structures and behaviors from the concept level down to the sensors and actuators within a district heating substation where we apply the SOA technology based on the open Arrowhead Framework. We focus on the Arrowhead Framework’s core services, i.e. Service Registry, Authorization and Orchestration to clearly describe the interactions between the different service providers and consumers. Going back up from the sensors to the systems, it is clear that SOA is the architecture that will empower the 4GDH.

Abstract [en]

This paper proposes a passive Barkhausen noise sensor design suitable for low power applications. The sensor uses a permanent magnet and the relative motion between itself and a measured specimen instead of the conventional method that uses a fixed sensor and an alternating magnetic field. Since this novel design is passive, the sensor is well suited for low power applications and could potentially be used in e.g. A condition monitoring system integrated into a rolling element bearing. Proof of concept testing has been performed showing that the proposed sensor produces similar results as conventional Barkhausen noise sensors when applied to specimens being cyclically loaded until failure in a rotating bending rig. The results imply that material fatigue detection using the Barkhausen noise can be performed with the proposed sensor at a fraction of the energy cost compared to a conventional sensor. This warrants future research into the development of the proposed sensor, its advantages, disadvantages, and functionality

Abstract [en]

This paper presents the technology concepts for a “thumb”-sized self-contained ultrasonic IoT measurement sys- tem. An overall architecture is proposed, and key elements are discussed with solutions using existing technology, thus arguing that realization is possible with the current technology.

Such an ultrasonic IoT measurement system is constrained by its size and available energy, although it requires at least decent computational and communication resources. Because streaming data from such a device is not advisable from an energy viewpoint, there is a need for resource efficient (energy, memory and computational power) data analysis.

An architecture with the following parts as well as some implementation details and performance data are proposed here:

  • Energy supply, battery and super capacitor

  • Transducer excitation achieving almost zero electrical losses

  • Event detection sensor interface

  • Data aggregation using sparse approximation and learned

    feature dictionaries, adapted to resource constrained em-

    bedded systems

  • IoT communication protocols and implementations enabling

    event -based communication and System of Systems integra- tion capabilities

    The optimization of system level performance requires each subsystem to be optimized for the specific measurement situation taking into account the subsystem interdependencies. This can be performed using a combined electrical and acoustical model of the system. Here, the model allowing electronic and acoustic co-simulation using SPICE is an important tool bridging the electronic and acoustic domains.

Abstract [en]

Various forms of cloud computing principles and technologies are becoming important recently. This paper ad- dresses cloud computing for automation and control applications. It’s argued that the open Internet cloud idea has such limitations that its not appropriate for automation.

Since automation is physically and geographically local, it is inevitable to introduce the concept of local automation clouds. It’s here proposed that local automation clouds should be self contained an be able to execute the intended automation func- tionalities without any external resources. Thus providing a fence at the rim of the local cloud preventing any inbound or outbound communication. Such a local cloud provides possibilities to address key requirements of both todays and future automation solutions. Adding mechanisms for secure inter-cloud administra- tion and data tranfere enables local automation cloud to meet IoT automation system requirements as: 1) Interoperability of a wide range of IoT and legacy devices 2) Automation requirement on latency guarantee/prediction for communication and control computations. 3) Scalability of automation systems enabling very large integrated automation systems 4) Security and related safety of automation systems 5) Ease of application engineering 6) Multi stakeholder integration and operations agility.

How these requirements can be met in such a local automation cloud is discussed with references to proposed solutions. The local automation cloud concept is further verified for a compartment climate control application. The control application included an IoT controller, four IoT sensors and actuators, and a physical layer communication gateway. The gateway acted as host for local cloud core functionalities. The climate control application has successfully been implemented using the open source Arrowhead Framework and its supports for design and implementation of self contained local automation clouds.

Abstract [en]

This paper presents a novel approach to automationof flexible manufacturing systems with mechatronic intelligenceand distributed control. The mechatronic intelligence layer isimplemented using a combination of wireless sensor/actuatornetworks with service-oriented architecture, where services arelocated at the device level, as well as in local and global Cloudsfollowing the Arrowhead framework.The machine/floor level coordination is implemented using thedistributed automation architecture of IEC 61499, which is alsoused as a graphical tool for orchestration of services.The paper discusses the enablers developed in-order to combineIEC 61499 and Arrowhead and the use is illustrated ona laboratory scale flexible factory example. By integration ofIndustrial IoT with IEC 61499, we envision that large gains interms of engineering effort and system operation performancecan be made.

Abstract [en]

When testing modern active safety systems on cars, it is essential to test vehicle response to steering inputs. This paper highlights the use of a path-following steering robot for repetitive car testing in winter conditions. Experiments have been made with commonly used test sequences, e.g., lane-change, double lane-change, constant radius circle, and handling circuit. The steering input from the human driver is replaced by a steering robot and a path-following algorithm. The main focus for this paper is to describe what happens when one pushes the path-following system to, and beyond, the physical limitations of road grip when cornering at high vehicle speed. It shows that, with an appropriate tuning of the path-following parameters, the system performs predictably and satisfactorily. The overall conclusion is that a path-following steering robot is indeed useful for repetitive test in winter conditions with poor road grip.
