Abstract:
AFDX (Avionics Full DupleX Switched Ethernet, ARINC 664) utilized in Airbus A380 and Boeing 787 represents a major upgrade in both bandwidth and capability; however some legacy systems are difficult to connect into the AFDX bus smoothly. A low cost AFDX end system based on SOPC (System On a Programmable Chip) is presented. A Xilinx Spartan 3AN FPGA is employed to build the whole system; and then a dedicated reduced Ethernet MAC controller for AFDX end system is designed; a MC8051 open core microcontroller is employed as the system controller and protocol processing unit. The whole design costs small FPGA resources and the experiments show that the designed AFDX end system works robustly and correctly.

Abstract:
Purpose This paper aims to focus on the implementation of the International Electrotechnical Commission (IEC) 61850–9-2 standard based process bus with merging units (MUs) and sampled values (SV) to improve the protection and control systems. The digital process interface is important to be included on the process bus level. Design/methodology/approach The IEC 61850–9-2 process bus standard is not extensively used in regard to SV when the IEC 61850 standard is implemented by power utilities. Many protection and control intelligent electronic devices (IEDs) are connected to a substation communication network, routers and switches using fibre-optic linked Ethernet. However, inductive current transformers (CTs) and voltage transformers (VTs) secondary circuits are still hardwired to the IEDs. The paper highlight issues with the copper wires for currents signals and how these issues can be eliminated by using the MUs and the SV protocol. The voltage regulator control IED of each transformer is required to regulate the voltage level of the secondary side bus bar it is connected to. All the regulating IEDs of parallel-connected transformers are required to communicate with each other to share information. They collectively control the bus bar voltage depending on the switching configuration of the parallel transformers. Findings It is shown that process bus information such as the high voltage switchgear status information of primary plant in the yard, can be used to improve the substation protection and control systems. The power transformer protection and voltage regulator control are focused on. Research limitations/implications The deliverables of the research work can be applied in: The Centre for Substation Automation and Energy Management systems of the Department of Electrical Engineering, power utilities and other establishments using power systems and digital substations in the electrical supply industry. The research work on the thesis led to the development of a laboratory test-bench where students can learn and understand the basics of the IEC 61850–9-2 SVs principles. The test-bench components such as the IEDs, real-time digital simulator, standalone MUs and Ethernet equipment can be used for future research applications. The test-bench can be used to demonstrate during course work for students at the University, the basics of digital substations using a process bus network with IEDs, MUs and Ethernet equipment. Practical implications The research work showed where lab equipment is getting outdated and future equipment will be required for research work in IEC 61850–9-2 process bus. Originality/value Power utilities can benefit from implementing the IEC 61850 part 9–2 of the standard and by using MUs and other process interface information in substations. A cost reduction in high voltage equipment, substation installation and commissioning costs and better performance of protection and control system can be achieved.

Abstract:
A simulation system on information flow is designed to emulate the data communication on the RS-485 bus, the 1553B bus and the Ethernet bus. This simulation system has a high requirement for the extendibility, and it must have an ability to regulate and reconfigure the information flow on the three buses. To deal with the above problems, the simulation system has to be designed as a reconfigurable extendible real-time multi-bus simulation system. In order to meet the real-time requirements for the simulation of the information flow and the universal property for the most systems, this simulation system must be carried out based on a real-time operating systems (VxWorks) and a common hardware platforms. Firstly, this simulation system will have a total emulation and a whole simulation for the information flow, the communication status, the monitor nodes and the control nodes on each of the three buses. Secondly, this simulation system defines an extendible protocol between the simulation sever and the simulation terminals, and strictly plan the information flow among the simulation terminals to achieve the design requirements of the actual system. And then the simulation system has to own a reconfigure software components and a complete database functions of recording and stacking the data.

Abstract:
In order to speed up the acquisition and processing of signal, this paper has developed a signal acquisition and processing system based on zynq platform. Based on the ARM Cortex-A9 dual-core and editable logic unit architecture of Zynq AP SoC platform, this paper implements a fully functional signal acquisition and processing system by software and hardware collaborative design. ARM0 is the main processor that controls system and shared resources. ARM1 is the slave processor. ARM1 is responsible for receiving the data converted by the AD7606 analog-to-digital chip. The data is sent to the Hamming window function IP core created under vivado HLS through the AXI bus. After the data is processed by Hamming window function, it is sent to ARM1 again through AXI bus. OCM acts as the shared memory for ARM0 and ARM1 communication. The Linux system runs on ARM0. The processed data is sent to the upper computer through ethernet through UDP protocol. Utilizing the architecture of the Zynq platform, the system efficiency is improved, and the stability of the system is ensured, so that the FPGA can enter the field of embedded systems.

Abstract:
Numerous military platforms (land, sea and air) feature serial data bus technology based on the US MIL-STD-1553B data bus standard for integration of their digital systems. Many of these platforms have 15-20 years of operational life remaining, but the installed 1553B data buses (data networks) having only a 1Mbit/sec transfer rate are unable to meet many of the future data networking requirements. Research into new, higher performance data networks has concentrated on modern alternatives with throughput increases of two to three orders of magnitude (100Mbit/sec to 1Gbit/sec). These are generally based on modern commercial-off-the-shelf (COTS) standards, good examples being Ethernet and Fibre Channel. Some are already being employed in military platforms having been ruggedised for the harsh physical and electro-magnetic environment. However these COTS systems while being a natural choice for new platforms may not be cost effective for upgrading older platforms. This paper plots the history of MIL-STD-1553, possibly the most successful military platform standard of all time, and discusses some of the options for increasing its performance and economically extending its life into the future.

Abstract:
With the global trend to digitalize substation automation systems, International Electro technical Commission 61850, a communication protocol defined by the International Electrotechnical Commission, has been given much attention to ensure consistent communication and integration of substation high-voltage primary plant assets such as instrument transformers, circuit breakers and power transformers with various intelligent electronic devices into a hierarchical level. Along with this transition, equipment of primary plants in the switchyard, such as non-conventional instrument transformers, and a secondary system including merging units are expected to play critical roles due to their fast-transient response over a wide bandwidth. While a non-conventional instrument transformer has advantages when compared with the conventional one, extensive and detailed performance investigation and feasibility studies are still required for its full implementation at a large scale within utilities, industries, smart grids and digital substations. This paper is taking one step forward with respect to this aim by employing an optimized network engineering tool to evaluate the performance of an Ethernet-based network and to validate the overall process bus design requirement of a high-voltage non-conventional instrument transformer. Furthermore, the impact of communication delay on the substation automation system during peak traffic is investigated through a detailed simulation analysis.

Abstract:
Electrohydraulic drives are primarily used whenever a low power/weight ratio, a compact build and/or large forces are required for individual applications. These drives are often used together with electric drive technology in machines. However, in terms of automation, unlike electric drives, electrohydraulic drives are still largely connected via analog interfaces and centralized closed control loops today. To compensate for this competitive disadvantage of hydraulic drive technology and, at the same time, significantly enhance its performance and diagnostics capability, a consistent automation solution has been developed that can be configured for both centralized and decentralized solutions. This contribution firstly gives an overview over this complete solution already available and its classification in the automation world. In a second step, the subset of decentralized drive solutions contained therein is presented in more detail and their benefits are explained on the basis of some exemplary applications.

Abstract:
Due to concerns about the negative impacts of powering vehicles using fossil fuel and the future availability of fossil fuel, there has been an increased focus on electric vehicles. However, current electric vehicle energy efficiency is a key problem as these vehicles are not as efficient as fossil-fueled vehicles. One way of decreasing a vehicle’s energy consumption is to reduce the weight of the vehicle, while still ensuring the safety and reliability of the vehicle. Controller Area Network (CAN) systems have been used in vehicles to realize real-time applications, however the low peak data rates of CAN have begun to limit the applications that can be realized. This bachelor’s thesis project focuses on secure communication within a vehicle using Ethernet. Additionally, the use of Power over Ethernet can be used for powering some of the network attached devices within the vehicle. The goal is to reduce the number of components and the weight of the vehicle while continuing to ensure the security and reliability of the communication – even when the network grows in size (either in physical size or in number of connected devices). This thesis shows that an Ethernet based system can serve as a possible replacement candidate for the CAN system due to its low latencies and high bandwidth. Ethernet is also a very scalable system with none of the limitations that a CAN system have.
Den negativa påverkan av fossila bränslen har de senaste årtionden haft en negativ på planeten, mängden fossila bränslen över världen konsumeras även i en högre takt än vad som produceras. Därför har fokusen för att finna förnybara energi källor som både är effektiva och inte påverkar miljön på ett negativt sätt ökat. Därför är elbilar en viktig del i konverteringen av enheter som drivs av fossila bränslen till förnybara energikällor. Ett av problemen i en elbil är att energi konsumptionen är inte lika effektiv som fossila bränslen inom bil industrin. Ett sätt att sänka energi konsumptionen är att minska mängden komponenter inom en bil för att minska på vikten, utan att påverka säkerheten och tillförlitligheten. Tidigare har man använt sig av ett CAN system för att försäkra sig om systemet fungerar felfritt i realtid, problematiken med detta system är att när nätverket ökar i storlek så sätter de fysiska begränsningarna av detta system stop för den garanterade säkerheten. Detta kandidatexamensarbete kommer att fokusera på den interna kommunikationen i en elbil med hjälp av ett ethernet baserat kommunkations system över CAN systemet. Power over Ethernet tekinken kommer att tillämpas för de systemen som kan drivas av detta system. Målet är att reducera antalet komponenter som behövs och att garantera säkerheten och tillförlitligheten av den interna kommunikationen när nätverket av komponenter ökar i storlek. Det här kandidatarbetet visar att Ethernet kan ersätta det nuvarande CAN systemet ef-tersom att Ethernet erbjuder låga latenser och hög bandbredd. Detta arbete visar även att Et-hernet är väldigt skalbart och har inte begränsingarna som ett CAN system har.

Abstract:
[eng] When Distributed Embedded Systems (DESs) operate in evolving environments, changing requirements might be imposed on the system, and thus the system needs the ability to adapt to them. Furthermore, when such systems are employed for real-time (RT) critical applications, both support for satisfying stringent RT guarantees and attaining a high level of reliability must be provided. The Flexible Time-Triggered (FTT) communication paradigm provides support for changing real-time traffic requirements in adaptive RT DESs, i.e., it provides RT flexibility. The different implementations of FTT on Ethernet have recently added to FTT advantages of Ethernet such as high bandwidth, low cost and, since Ethernet is the de facto Link Layer standard of many communication systems, also an easier potential integration. A specific FTT implementation on Ethernet, called Flexible Time-Triggered Ethernet Star (FTTRS), has been recently proposed to add mechanisms to tolerate faults in the channel as a means to increase the reliability of the final system. However, it is known that to reach a very high level of system reliability it is crucial to also tolerate faults in the computation nodes. This is so because the computation nodes are usually the most complex components of a DES and, hence, they are less reliable than most of the components that constitute the channel, e.g. the links. This thesis proposes a node replication architecture and appropriate node faulttolerance (FT) mechanisms so as to attain a high level of reliability for critical RT DES. The proposed architecture and FT mechanisms are based on an active node replication strategy with distributed majority voting. The mechanisms are designed on top of FTTRS in order to take advantage of the features that the FTT paradigm and the FTTRS communication subsystem already provide in terms of channel RT flexibility and channel fault tolerance. We start by introducing the concepts, terminology and methodology used to specify, design and test a fault-tolerant system. Special attention has been paid to describing the specific fault-tolerance techniques used in this dissertation. Also, we present the foundations on top of which we develop our node FT mechanisms. In particular we present the FTT communication paradigm and the details of the FTTRS itself. Then, we describe the main contributions of this dissertation. We start by a general description of the overall system. Then, we clarify what types of faults (fault model) we address, and we thoroughly describe and classify all the manners in which these faults may manifest (failure model). Afterwards we focus on describing the proposed FT mechanisms based on both active node replication and FTTRS. Once this description is completed, we propose a realization of the designed FT mechanisms for the specific case of control applications. Moreover, in order to test and verify the correctness of our node replication architecture and FT mechanisms, we present a simulation model as well as a real prototype. We use these simulation model and real prototype to thoroughly inject faults (in terms of all the manners in which faults can manifest according to the failure model) and, then, we inspect if the mechanisms function as intended in both of them. Finally, we build a dependability model to quantify the level of reliability attainable by a DES relying on our node replication architecture and FT mechanisms. By means of the work described in the current dissertation we prove the following thesis statement: “It is possible to attain high levels of reliability of adaptive critical RT DES that rely on a reliable and flexible RT communication subsystem based on an FTT implementation on Ethernet by providing FT mechanisms for the nodes.”
[spa] Los sistemas empotrados distribuidos son sistemas compuestos por un conjunto de nodos interconectados que trabajan para lograr un objetivo común y que forman parte de un sistema mecánico o eléctrico más grande. Los nodos suelen estar interconectados por medio de una red de comunicación. En cuanto a las redes de comunicación, en las últimas décadas Ethernet se ha convertido en una de las tecnologías más populares debido a sus muchas ventajas tales como simplicidad, anchos de banda siempre crecientes y bajo coste, entre otras. Cuando los sistemas empotrados distribuidos forman parte de sistemas más grandes que ejecutan aplicaciones críticas, a menudo existe la necesidad de proporcionar un soporte para requisitos de respuesta en tiempo real y para la consecución de una muy elevada fiabilidad. La tecnología original de Ethernet no proporciona ningún soporte de este tipo. Por lo tanto, en esta disertación usamos el recientemente propuesto subsistema de comunicación que recibe el nombre de Flexible Time-Triggered Replicated Star (FTTRS) como medio para interconectar los nodos de los sistemas empotrados distribuidos que ejecutan aplicaciones críticas. FTTRS toma la tecnología de red Ethernet como base y sobre ella proporciona mecanismos para soportar respuesta en tiempo real y elevada fiabilidad. La respuesta en tiempo real es proporcionada por el uso del paradigma de comunicación Flexible Time-Triggered (FTT) implementado sobre el protocolo Ethernet el cual, además de la provisión de garantías de tiempo real, también proporciona flexibilidad, en concreto, la capacidad de modificar el comportamiento de la red en tiempo de ejecución mientras se mantienen las garantías de tiempo real comprometidas. La elevada fiabilidad en FTTRS se logra mediante mecanismos que toleran los fallos que podrían afectar a la comunicación entre nodos. Sin embargo, proporcionar tolerancia a fallos únicamente al subsistema de comunicación no es suficiente para satisfacer los requisitos de fiabilidad más exigentes de las aplicaciones críticas. Para alcanzar altos niveles de fiabilidad, los fallos en los propios nodos del sistema empotrado distribuido también deben ser tratados. En consecuencia, hemos diseñado varios mecanismos de tolerancia a fallos para tratar los fallos que puedan afectar al correcto funcionamiento de los nodos. Estos mecanismos aprovechan las características del subsistema de comunicación FTTRS y del paradigma de comunicación FTT subyacente. Concluyendo, en esta tesis veremos cómo podemos, con la introducción de mecanismos específicos para tolerar los fallos de los nodos de un sistema empotrado distribuido basado en FTTRS, lograr muy elevados niveles de fiabilidad para el sistema en su conjunto. Además del diseño de los mecanismos de tolerancia a fallos de los nodos, también mostraremos cómo se puede evaluar la fiabilidad resultante y estableceremos cuál es el beneficio obtenido, comparando dicha fiabilidad con la de una versión no tolerante a fallos del mismo sistema.

Per tant, en aquesta dissertació usem el recentment proposat subsistema de comunicació que rep el nom de Flexible Time-Triggered Replicated Star (FTTRS) com a mitjà per interconnectar els nodes dels sistemes encastats distribuïts que executen aplicacions crítiques. FTTRS pren la tecnologia de xarxa Ethernet com a base i sobre ella proporciona mecanismes per suportar resposta en temps real i elevada fiabilitat. La resposta en temps real és proporcionada per l’ús del paradigma de comunicació Flexible Time-Triggered (FTT) implementat sobre el protocol Ethernet el qual, a més de la provisió de garanties de temps real, també proporciona flexibilitat, en concret, la capacitat de modificar el comportament de la xarxa en temps d’execució mentre es mantenen les garanties de temps real compromeses. L’elevada fiabilitat en FTTRS s’aconsegueix mitjançant mecanismes que toleren les fallades que podrien afectar a la comunicació entre nodes. En qualsevol cas, proporcionar tolerància a fallades únicament al subsistema de comunicació no és suficient per satisfer els requisits de fiabilitat més exigents de les aplicacions crítiques. Per aconseguir alts nivells de fiabilitat, les fallades en els propis nodes del sistema encastat distribuït també han de ser tractades. En conseqüència, hem dissenyat diversos mecanismes de tolerància a fallades per tractar les fallades que puguin afectar al correcte funcionament dels nodes. Aquests mecanismes aprofiten les característiques del subsistema de comunicació FTTRS i del paradigma de comunicació FTT subjacent. Concloent, en aquesta tesi veurem com podem, amb la introducció de mecanismes específics per tolerar les fallades dels nodes d’un sistema encastat distribuït basat en FTTRS, aconseguir molt elevats nivells de fiabilitat per al sistema en el seu conjunt. A més del disseny dels mecanismes de tolerància a fallades dels nodes, també mostrarem com es pot avaluar la fiabilitat resultant i establirem quin és el benefici obtingut, comparant aquesta fiabilitat amb la d’una versió no tolerant a fallades del mateix sistema.

Abstract:
Avec l’évolution des technologies de l’internet, les applications et plus généralement lessystèmes distribués sont de plus en plus conçus en composant et interconnectant un ensemblede services distribués. Ces services pouvant être très hétérogènes, plusieurs approches etsolutions pour la gestion de l’intégration et l’interopérabilité ont été proposées. De toutes cespropositions, les bus de services (ESB – Enterprise Service Bus) ont été désignés commeétant la solution la plus adaptée. Toutefois, le problème avec les ESB est qu’ils sont déployésdans un contexte très évolutif et très dynamique; un contexte dans lequel un grand nombre deservices peuvent être fournis et utilisés de façon concurrente à travers le bus. L’utilisationconcurrente de ces services mais aussi des ressources sous-jacentes allouées au bus (mémoire,processeur, etc.) peut conduire à des événements imprévisibles tels qu’une surcharge du bus,une indisponibilité des services, des temps de réponse élevés, une diminution de la fiabilité,etc. Dans ce contexte, des solutions efficaces permettant de garantir ou d'améliorer à la fois laqualité de service et l'évolutivité offertes par les ESB sont nécessaires. Le but de cette thèse est de proposer les principes architecturaux pour la mise en place un busde service autonome (ASB) qui offre une solution de communication scalable guidée par lestransactions des systèmes interconnectés, mais aussi par les ressources disponibles. L’ASBoffre aussi un service d’intégration différentiée en fonction des exigences en termes de qualitéde service spécifiques aux systèmes interconnectés

Diversity and heterogeneity of these services raise important integrabilityand interoperability requirements. To meet these needs, the Enterprise Service Bus (ESB) hasbeen proposed as a mediator based on open and standard interfaces facilitating theintegrability and interoperability of services. However, in very active and dynamic contextswhere a large number of concurrent services can be provided and consumed via the ESB, thecompetition for using shared services, but also the underlying computing resources allocatedto the ESB (memory, processor, etc.) can lead to unpredictable events such as serviceunavailability, high response time, decrease of reliability, etc. Such anomalies need to beaddressed by proposing efficient strategies able to guarantee or to improve both the QoS andscalability offered by the ESB. The aim of this thesis is to propose an architectural framework for a QoS-aware AutonomicService Bus (ASB) able to offer in an autonomic way a scalable communication solutionguided by distributed systems transactions and the state of the underlying computingresources. The ASB offers also a differentiated integration service based on the QoSrequirements of interconnected systems

Abstract:
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada
The telemetry industry anticipates the tremendous potential value of adding full networking capability to telemetry systems. However, much of this potential can be realized while working with legacy equipment. By adding modules that interface transparently to existing equipment, continuous telemetry data can be encapsulated in discrete packets for over the air transmission. Packet fields can include header, sequence number and bytes for error detection and correction. The RF packet is transmitted without gaps through a standard serial interface and rate adjusted for the packet overhead – effectively making packetization transparent to a legacy system. The receiver unit performs packet synchronization, error correction, extraction of stream quality metrics and re-encapsulation of the payload data into an internet protocol (IP) packet. These standard packets can then be sent over the existing network transport system to the range control center. At the range control center, the extracted stream quality metrics are used to select the best telemetry source in real-time. This paper provides a general discussion of the path to a fully realized, packet-based telemetry network and a brief but comprehensive overview of the Hypernet system architecture as a case study.

Abstract:
The current regulatory and planning environment means that road-based public transport in UK urban areas (with the exception of London) tends to be planned on a piecemeal basis, and there are often conflicts between the needs and priorities of operators, passengers and planners. In consequence, several local authorities are considering adopting an alternative regulatory environment using quality contracts, with a consequent shift towards centralised service planning. There are though no tools readily available to ensure this centralised service planning will lead to a situation which provides a better balance between the interests of the different stakeholders. This thesis describes the development of a methodology to fill this gap, using Southampton as a case study to diagnose issues with its current bus network, and to explore the corresponding improvement methods which could be applied based on the alternative regulatory environment. Gravity-based accessibility levels from population-weighted centroids of postcodes to key services were calculated as an indicator to measure the performance of the current bus network in Southampton. Based on the accessibility analysis, service improvements, including both route planning and frequency setting, can be developed for the Southampton bus system under the alternative regulatory environment. This service improvement problem is then solved by making use of an optimisation technique, the tabu search algorithm, developed under the environment of ArcObjects for Java. The methodology described above has been shown to work well for the Southampton case study, and the outputs from the optimisation model indicate that the model can deliver a bus network which provides a higher level of accessibility under the alternative regulatory environment. While the methodology is developed in the UK context, the general principles used could be applied more widely to improve transit network planning.

Abstract:
In the last years the steady development of autonomous driving technology has enabled the deployment of more mature autonomous vehicles. These vehicles have been applied in several pilot projects worldwide, most commonly in the form of small buses. At the same time, the amount of people traveling in especially urban areas is continuously growing, resulting in more trips in the transportation system. An efficient transportation system is therefore required to serve the growing passenger demand. Autonomous buses (AB) are assumed to have lower operational costs and with that public transport (PT) systems can potentially be designed more efficiently to facilitate the increased demand better. In this study, an AB specific simulation-based optimization framework is proposed which allows analyzing the impacts AB have on line-based PT systems. The thesis focuses on the transition from existing PT systems towards line-based PT systems operated partially or exclusively by AB. Existing work on PT service design is extended so that realistic AB systems can be investigated. This is achieved by (i) using AB specific operator cost formulations, (ii) integrating infrastructure costs required for AB operations, (iii) utilizing a dynamic, stochastic and schedule-based passenger assignment model for the simulation of PT networks and by (iv) formulating a multi-objective optimization problem allowing to investigate the stakeholder-specific impacts of AB. In Paper I the effects of AB, concerning service frequency and vehicle capacity, on fixed-line PT networks are investigated. Among other metrics, the changes are evaluated based on differences in level of service and passenger flow. Additionally, the sequential introduction of AB in existing PT systems is studied. The framework addresses a case study in Kista, Sweden. The study confirmed the initial hypothesis that the deployment of AB leads to an increase in service frequency and a marginal reduction in vehicle capacity. Furthermore, it could be seen that the deployment of AB increases the passenger load on AB lines and that passengers can shift from other PT modes towards the AB services. Paper II incorporates a multi-objective heuristic optimization algorithm in the simulation framework. The study investigates changes in transport network design based on the deployment of AB. The differences in user-focused and operator-focused network design are analyzed and the impact of AB on these is quantified. This study is applied to a case study in Barkarby, Sweden where a full-sized, line-based PT network is designed to exclusively operate AB. Among other findings, we show that the autonomous technology reduces the number of served bus stops and reduces the total PT network size. Additionally, average passenger waiting time can be reduced when deploying AB on user-focused PT networks, which in turn leads to a further reduction of user cost.
De senaste årens framsteg inom autonom körteknik har lett till mer mogna autonoma fordon. Dessa fordon har setts tillämpas i flera pilotprojekt över hela världen, oftast i form av små bussar. Samtidigt växer mängden människor som reser, särskilt i stadsområden, kontinuerligt vilket resulterar i fler resor i transportsystemet. Därför krävs ett effektivt transportsystem för att tillgodose det växande antalet passagerare. Autonoma bussar (AB) antas ha lägre driftskostnader och därmed kan system för kollektivtrafik (public transport, PT) potentiellt utformas mer effektivt för att underlätta den ökade efterfrågan bättre. I denna studie föreslås ett AB-specifikt simuleringsbaserat optimeringsramverk som gör det möjligt att analysera effekterna AB har på linjebaserade PT-system. Avhandlingen fokuserar på övergången från befintliga PT-system till linjebaserade PT-system som delvis eller uteslutande drivs av AB. Befintligt arbete med PT-tjänstdesign utvidgas så att realistiska AB-system kan undersökas. Detta uppnås genom att (i) använda AB-specifika operatörskostnadsformuleringar, (ii) integrera infrastrukturkostnader som krävs för AB-verksamhet, (iii) använda en dynamisk, stokastisk och schemabaserad modell för att tilldela passagerare vid simulering av PT-nät samt genom att (iv) formulera ett multifunktionellt optimeringsproblem som gör det möjligt att undersöka AB: s intressespecifika effekter. I artikel I undersöks effekterna av AB, med avseende på servicefrekvens och fordonskapacitet, på fasta linjer i PT-nät. Förändringar utvärderas bland annat utifrån skillnader i servicenivå och passagerarflöde. Dessutom studeras den sekventiella introduktionen av AB i befintliga PT-system. Det föreslagna ramverket tillämpas på en fallstudie i Kista, Sverige. Studien bekräftade den initiala hypotesen att utplaceringen av AB leder till en ökning av servicefrekvensen och en marginell minskning av fordonens kapacitet. Vidare kunde man se att utplaceringen av AB ökar passagerarbelastningen på AB-linjer och att passagerare kan skifta från andra PT-former mot AB-tjänsterna. Artikel II integrerar en multifunktionell heuristisk optimeringsalgoritm i ramverket för simuleringen. Studien undersöker förändringar i transportnätverkets design baserat på implementeringen av AB. Skillnaderna i användarfokuserad och operatörsfokuserad nätverksdesign analyseras och AB: s inverkan på dessa kvantifieras. Denna studie tillämpas på en fallstudie i Barkarby, Sverige, där ett fullstort linjebaserat PT-nät är utformat för att exklusivt driva AB. Vi visar bland annat att den autonoma tekniken reducerar antalet använda busshållplatser och reducerar den totala PT-nätstorleken. Dessutom kan implementeringen av AB på användarfokuserade PT-nät ytterligare förbättra servicenivån främst genom att minska den genomsnittliga väntetiden per passagerare.

Abstract:
Traditional Computer Numerical Control (CNC) machines use ISO6983 (G/M code) for part programming. G/M code has a number of drawbacks and one of them is lack of interoperability. The Standard for the Exchange of Product for NC (STEP-NC) as a potential replacement for G/M code aims to provide a unified and interoperable data model for CNC. In a modern CNC machine tool, more and more motors, actuators and sensors are implemented and connected to the NC system, which leads to large quantity of data being transmitted. The real-time Ethernet field-bus is faster and more deterministic and can fulfill the requirement of data transmission in the high-speed and high-precision machining scenarios. It can provide more determinism on communication, openness, interoperability and reliability than a traditional field-bus. With a traditional CNC system using G/M code, when the machining is interrupted by incidents, restarting the machining process is time-consuming and highly experience-dependent. The proposed CNC controller can generate just-in-time tool paths for feature-based machining from a STEP-NC file. When machining stoppage occurs, the system can recover from stoppage incidents with minimum human intervention. This is done by generating new tool paths for the remaining machining process with or without the availability of the original cutting tool. The system uses a real-time Ethernet field-bus as the connection between the controller and the motors.

This is report of design, construction and control of “Ariana-I”, an Underwater Remotely Operated Vehicle (ROV), built in Shiraz University Robotic Lab. This ROV is equipped with roll, pitch, heading, and depth sensors which provide sufficient feedback signals to give the system six degrees-of-freedom actuation. Although its center of gravity and center of buoyancy are positioned in such a way that Ariana-I ROV is self-stabilized, but the combinations of sensors and speed controlled drivers provide more stability of the system without the operator involvement. Video vision is provided for the system with Ethernet link to the operation unit. Control commands and sensor feedbacks are transferred on RS485 bus; video signal, water leakage alarm, and battery charging wires are provided on the same multi-core cable. While simple PI controllers would improve the pitch and roll stability of the system, various control schemes can be applied for heading to track different paths. The net weight of ROV out of water is about 130kg with frame dimensions of 130×100×65cm. Ariana-I ROV is designed such that it is possible to be equipped with different tools such as mechanical arms, thanks to microprocessor based control system provided with two directional high speed communication cables for on line vision and operation unit.

Abstract:
A networked control system (NCS) is a control architecture where sensors, actuators and controllers are distributed and interconnected. It is advantageous in terms of interoperability, expandability, installation, volume of wiring, maintenance, and cost-effectiveness. Many distributed network systems of various topologies and network type have been developed, but NCS systems tend to suffer from such issues as nondeterminism, long network delays, large overheads and unfairness. This paper presents the ring-based protocol, called the ExoNet, and its network architecture which are built to achieve better performance as a distributed networked system. A Cypress transceiver CY7C924ADX is applied to the network as a communication unit. The protocol is based on the transceiver and developed to achieve fast communication and allowable latency for controls with high control loop frequency. Compared with other standard network types such as Ethernet, ControlNet or DeviceNet, the network is characterized by its ring-based architecture, simple message and packet formats, one-shot distribution of control data and collection of sensor data, multi-node transmission, echo of a message, and other features. The network also guarantees determinism, collision-free transmission, relatively small overhead, fairness between nodes and flexibility in configuration. Its analysis and comparison with these network types are also provided and its application on the Berkeley Lower-Extremity Exoskeleton (BLEEX) is described.

Abstract:
Transpetro — the transportation division of Petrobras — operates approximately 10.000 kilometers of pipelines and 43 oil terminals. It is the main oil and gas logistic company in Brazil and one of the top companies in Latin America. This work presents a concise description of Transpetro’s project to integrate these distributed sites. Most of the pipelines are remotely operated by the Operational Control Center (OCC), located in Rio de Janeiro, but there are also a number of pipelines and specific operations that are under the responsibility of the terminals, and these operations are called “distributed operations”. These operations include pump and compressors control, valves alignment, products quality monitoring, and even some pipelines control not integrated to the OCC yet, such as the ones that are used to deliver final products to the distribution companies. Each of the Terminals has, or is receiving, an automation system including instrumentation, programmable logic controllers, communication and supervisory systems. Pressure, density, flow and level are some of the variables collected by the automation system and made available to the terminal operator. The system also allows the remote control of valves, bombs, compressors and other equipment. All this information gathered by the automation system becomes digitally available on the level of the terminals supervisory systems, which in Transpetro are mainly based on Intellution iFIX and Telvent OASyS. Therefore, other systems can access the supervisory systems and use its digital information for the benefit of the company. On the Operational side, there are some specialist systems that refine and sophisticate the level of information available in the supervisory system. One of these is the Leak Detection System, which interfaces with the supervisory system using data transfer protocols such as DDE and OPC, receiving the process data and applying a computational model that allows the operator to identify a potential leak. In a Logistic Company such as Transpetro, it is important to keep all the information concerned to storage (in tanks or pipelines), both current and scheduled operations, in a set of systems functioning in an integrated way. One of these systems is the homemade one called BDEMQ (Storage, Transportation and Quality Data Base). Transpetro is now implementing the interface between the automation systems and BDEMQ in all terminals. The technology used is a C and Java language-based interface through an Ethernet TCP/IP network. Hence, once Transpetro has all the data digitalized in its terminals’ automation systems, it is possible to improve the level of control and information, increasing the support to the operators’ and managers’ decision taking processes.
