  • Designing Robust Wireless Communications for Factory Floors

    Page(s): xxviii - xxix
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (89 KB)  

    Summary form only given. The tutorial is aimed at teaching the underlying aspects of short-range, wireless RF-links (of WLAN and WPAN specifications) that are considered in the state-of-the-art factory informatic communication applications. Such wireless links on industrial floors may prevail across a variety of end-entities such as computer hosts, robots, sensor-mounted autonomous moving units (in production series), and roaming workers with PDAs. Ideally, relevant connectivity should conform to robust performance despite of harsh electromagnetic environment and mutual interference (due to co-location) inherent to industrial floors. At the same time, these connections should be economically viable and operate on low-power budgets. Based on service classes, their range is specified -from a meter to 100 meters. Interoperability with other communication (wireline or wireless) systems and feasibility of extension into inter- and/or intra networking of the factory could be another set of desirable features. Retrofit considerations, compact size of the radio units, portability and ad hoc networking are other aspects of forward-looking factory communication perspectives. Starting from the aforesaid underlying concepts, a step-by-step tracing of working principles of these RF links vis- -vis factory communications will be aimed at in the tutorial lectures. The associated prospects of the upcoming technology conceived to bring about the existence of a broad range of interoperable factory-based devices through open-industry specifications on unlicensed, untethered peripheral and control unit that operate on low-cost and low-power budgets and enabling communications between complaint devices anywhere in and around an indoor factory environment will be elaborated. Hence the RFI compatibility issues and design aspects of making the links robust via diversity techniques will be indicated. View full abstract»

  • Service-oriented Architectures in Industrial Automation

    Page(s): xxxii - xxxiii

    The advent of the service-oriented architecture (SOA) paradigm is a major trend in the ICT industry at large. Based on open standards and protocols and enjoying broad-based industry adoption, it is set to revolutionize the computing and communications landscape in the years to come. Current literature abounds with articles on SOA - especially SOA implemented using Web services. However, SOA is much more than a buzz word. Being an enterprise-wide architectural style that promotes vendor neutrality, interoperability, and loose-coupling between service providers and consumers, it is rapidly becoming the de-facto foundation for enterprise architectures. Ever-increasing miniaturization allows driving intelligence down to the device level, thus favoring the adoption of the SOA paradigm in the embedded-device space, down to sensors and actuators. This will enable radically new device networking architectures and pave the way for application of a uniform communication paradigm down from the shop floor up to the top floor, thus breaking down current technological barriers. In turn, these evolutions hold the promise of greatly increasing the agility of future industrial enterprises. This tutorial exposes the foundations of the SOA paradigm in general and of its use in the device space in particular, explains how SOA for devices can be implemented using the Devices Profile for Web Services, and outlines the benefits it brings in the industrial sector, as illustrated by the ground breaking experience of the SIRENA (http://www.sirena-itea.org) project. It further plots some future directions and discusses the potential benefits of using advanced concepts like semantic Web services for automating service selection, invocation and composition, so as to facilitate rapid reconfiguration.

    Service oriented architecture (SOA) is attended as a design framework for realizing rapid and low-cost system development, easily modified system, and total system quality. SOA is mainly applied to business information systems using Web services standards and technologies, and is rapidly becoming a standard approach for enterprise IT systems. In industrial systems, SOA has been successfully applied such as SCM, order entry system, etc. However, in the low layer management and control systems, Web services cannot apply because of particular requirement. The specific functions needed to apply the concept of SOA to real-time system (response time, support of event-driven, asynchronous parallel applications, complicated human interface support, reliability, etc.). First of this talk, SOA will be briefly explained. Then, we will point out several issues arisen when the concept of SOA applied to the industrial systems. Finally, example industrial systems (business systems and command and control systems) applied SOA will be introduced. View full abstract»

    Modern design approaches for manufacturing system organize the control architecture in the same way as the functional structure of the plant. This leads to a modular approach that is based on composition of automation components. This paper introduces a hierarchical architecture that is based on a generic internal structure of automation components. This includes logic, diagnostics as well as human machine interface (HMI). The HMI architecture is again organized in the same way as the functional structure of the plant. This results in a clear modelling process enabling reduced engineering effort and simple maintenance. It can also serve as a basic architecture for reconfiguration approaches. View full abstract»

  • Applying the handler-based execution model to IEC 61499 basic and composite function blocks

    Page(s): 18 - 24

    We defined the so-called "handler-based execution model" as a real-time capable execution model for CNet [H. Wurmus, 2002] [N. Hagge and B. Wagner, 2005]. Traditional controller implementations typically consist of big loops with a fix sequential execution scan order. This was not appropriate for Petri-net based CNet that is characterized by a high degree of concurrency and locality. Our execution model is purely based on events to dynamically schedule the evaluation of firing conditions and avoids unnecessary calculations. There are no global event queues. Event-flow is handled locally which is beneficial for multithreaded and/or distributed platforms. This execution model is part of a full automatic code generator that translates CNet controller models into (real-time) Java code. Examining IEC 61499 revealed that function blocks networks similarly feature concurrency and locality, but that execution environments for function blocks are still developed based on traditional fixed sequential scan approaches. This paper will introduce the main concepts of the "Handler- based execution model" and show its possible application to IEC 61499 function blocks for automatic code generation. View full abstract»

    The paper deals with the implementation of IEC 61499 applications into executable code. In particular, this work concerns the automatic conversion of a IEC 61499 application into an AWL application executable on a standard Siemens PLC. The IEC 61499 Standard defines an application as a network made of Function Blocks and event/data connections. The behaviour of a single Function Block and of an application is also specified in the standard. At the moment, there are no industrial solutions supporting this standard: from that the need to cover the gap between the standard and the existing legacy devices. View full abstract»

    Since IEC 61499 has reached the state of an international standard and a substantial body of research results exists the question of the authors as main intention for this paper was: Do the models of IEC 61499 solve all problems when thinking of usability and interoperability in heterogeneous system environments? The main problems discussed within the paper concern to the execution model defined for basic function blocks and the scheduling of events within function block networks. View full abstract»

  • Adaptive Autopilot System for Small Ships Employing E-TOP Method and SOM

    Page(s): 38 - 43

    A phase diagram of error and its derivative is useful to illustrate the state of the control system, where a fixed point at origin stands for a stable state, a point leaving origin an unstable state, a point moving round the origin an oscillatory state, etc. Thus the state of the control system is estimated by the motion of the point in the diagram. When the control system is under a strong or periodic disturbance, the state point moves round the origin staggeringly or periodically. It is difficult to evaluate the state of the control system in such conditions and the appropriate control is hardly realized. The E-TOP (evaluation with trajectory on phase diagram) method, presented by the authors, facilitates extracting the feature parameters from the trajectory in the phase diagram. The feature parameters characterize the behaviour of the control system. The adaptive PID autopilot system employing the E-TOP method is very efficient to evaluate the behaviour of small ships, the attitude of which is easily varied by the waves. However, when the attitude of the ship body is strongly staggering, the adaptive autopilot system cannot work appropriately. To cope with this problem, we propose the advanced E-TOP adaptive PID autopilot system, which employs the self-organizing maps (SOM)[2]. The advantage of this autopilot system to the conventional one is shown by the software simulation. View full abstract»

    It is no doubt that RFID technology is of very widespread applications. With RFID deployment scales-up, its application becomes more and more network-centric. The design of RFID network hence plays a critical role for successfully deploying large-scale applications. This is especially true when the tagged object is on item-level. This paper discusses issues that should be considered in design of RFID network; analyzes the potential impacts of different RFID network design on the existing enterprise network; presents a distributed design of RFID network for large-scale deployment. The paper also quantifies packet size of RFID data based on EPC serialized number; analyzes bandwidth requirement of RFID traffic for the diversified number of readers to illustrate the necessity of the distributed design, which authors believe are helpful for the earlier adopters of RFID technology, and may ignite more researchers and pioneering practitioners involving R&D along this direction. As a case study, the paper presents a cost-effective, sound and efficient RFID network design for retail. View full abstract»

    This paper presents an innovation of a Near Field Communication (NFC) and Bluetooth bridge system for connecting Bluetooth enabled mobile devices to NFC enabled consumer services. Nowadays, there is an abundance of mobile phones and PDAs with Bluetooth capability in the consumer market but there are fewer devices with NFC capability. In order for NFC enabled consumer services and payment to be rapidly adopted in the consumer market, it is therefore important to make the service available to a larger sector of the consumer market without NFC connectivity. The proposed system comprises a NFC-Bluetooth bridge and a software driver program. The NFC-Bluetooth bridge is an electronic device with two air interfaces: Bluetooth and NFC. The Bluetooth air interface is for establishing a wireless connectivity with Bluetooth devices and the NFC air interface is for establishing a wireless connectivity with NFC devices. The software driver is a tiny software program for driving communication between the Bluetooth and NFC devices and can be downloaded and run in mobile devices. This paper presents the system architecture and computational algorithms for the proposed system, and also illustrates its use for mobile consumer service and payment. View full abstract»
