Roll-to-roll systems handling web material such as papers, polymers, textiles or metals are very common in the industry. Web handling systems are recently used to produce new technologies such as printed semi-conductors, thin solar panels, printed electronics, etc. In web handling systems, one of the main objectives is to reach a good accuracy of web tension and web speed. For the tuning of machineries, one-dimensional models are commonly used and they do not take into account several three-dimensional mechanical phenomena initiated by lateral components of the elastic web dynamics. It is necessary to develop new models in order to optimize roll-to-roll systems. This paper presents for the first time robust control applied to web dynamics modeled in 3D, including web tension decoupling between consecutive web spans.
卷对卷系统处理卷筒纸材料,如纸张,聚合物,纺织品或金属是非常常见的行业。卷筒纸处理系统最近被用于生产印刷半导体、薄太阳能板、印刷电子等新技术。在卷筒纸处理系统中,主要目标之一是达到良好的卷筒纸张力精度和卷筒纸速度。对于机械的调谐,通常使用一维模型,它们没有考虑由弹性腹板动力学的横向分量引起的几种三维力学现象。为了优化卷对卷系统,有必要开发新的模型。本文首次将鲁棒控制应用于三维腹板动力学建模,包括连续腹板跨间的腹板张力解耦。

The number of devices connected to the Internet of Things (IoT) has steadily been increasing over the last years and so has the variety of applications. There is no sign for this trend to weaken. A broad subset of them imposes requirements on attributes, such as availability, reliability, safety and many more. These attributes are commonly subsumed under the term dependability. In this paper we first give a brief introduction to dependability. Three application scenarios typical for the IoT are presented and their demands for each dependability attribute are discussed. Furthermore, an overview of the current state of the art is presented. Last, a summary of required technologies and future research topics to enable dependability in the IoT is given.

In the last years a new computing paradigm called Internet of Things (IoT) has been gaining more attention. This paradigm has become popular by embedding mobile network and processing capability into a wide range of physical computing devices used in everyday life of many people. An important part that composes the IoT is the middleware, which is a system that abstracts the management of physical devices and provides services based on the information of these devices. Context-aware is an important feature of IoT middleware systems. This feature allows to discover, understand, and store relevant information related to devices and their respective events. In this sense, this work aims to present an ongoing system that has been developed to provide services of contextualized information about IoT devices in heterogeneous environments.

Location Aided Zone Routing Protocol in Mobile Ad Hoc Networks 移动自组织网络中的位置辅助区域路由协议
Pub Date : 2015-10-26 DOI: 10.1109/ETFA.2015.7301615

This paper proposes a geographical routing algorithm based on Zone Routing Protocol (ZRP) to limit the area for discovering a new route by utilizing location information of nodes. Mobile Ad Hoc Networks (MANETs) have attracted much attention in the research and the industry. In MANETs using ZRP algorithm, nodes use Route REQuest messages (RREQs) to obtain a new route often by bordercasting them to other nodes in the network if they does not find out the destination in their routing zone. This dissemination mechanism guarantees to seek a route from source to destination with high probability. However, it creates many useless routing overhead packets while limited bandwidth and energy consumption are very important issues in MANETs. In order to reduce routing overhead, this paper proposes an approach name Location-Aided Zone Routing Protocol (LAZRP). Simulation results confirm that the proposed algorithm can depress routing overhead and end-to-end delay.
本文提出了一种基于区域路由协议(Zone routing Protocol, ZRP)的地理路由算法,利用节点的位置信息来限制发现新路由的区域。移动自组网(manet)在研究和业界受到了广泛的关注。在使用ZRP算法的manet中,如果节点在自己的路由区域内没有找到目的地,则节点通常通过边界铸造路由请求消息(Route REQuest message, rreq)来获得新的路由。这种传播机制保证了高概率地寻找从源到目的的路由。然而,它产生了许多无用的路由开销数据包,而有限的带宽和能量消耗是manet中非常重要的问题。为了减少路由开销,本文提出了一种定位辅助区域路由协议(LAZRP)。仿真结果表明,该算法可以降低路由开销和端到端时延。

In the area of product-based control of manufacturing processes, the potential to integrate intelligent products in process control has been recognized several times. However, the effect of greatly varying intelligent products on the control and hybrid system dynamics of the individual (sub-) processes have not been investigated. This article begins with a definition of product-intelligence and a distributed data and interface model. Based on this, a decentralized hybrid reconfiguration structure with different intelligence-based reconfiguration strategies as a function of varying product properties is presented, using the example of a conveyor belt system. Through the implementation on a industrial controller, it has been shown that the concept represents a further module in the realization of cyber-physical systems through comprehensive analysis and synthesis of a highly flexible hybrid control loop.

Modbus/TCP is a network protocol for industrial communications encapsulated in TCP/IP network packets. There is an increasing need to test existing Modbus protocol implementations for security vulnerabilities, as devices become accessible even from the Internet. Fuzz testing can be used to discover implementation bugs in a fast and economical way. We present the design and implementation of MTF, a Modbus/TCP Fuzzer. The MTF incorporates a reconnaissance phase in the testing procedure so as to assist mapping the capabilities of the tested device and to adjust the attack vectors towards a more guided and informed testing rather than plain random testing. The MTF was used to test eight implementations of the Modbus protocol and revealed bugs and vulnerabilities that crash the execution, effectively resulting in denial of service attacks using only a few network packets.

In this paper an approach for controlling overhead cranes by avoiding oscillations is proposed and experimentally tested. In particular, a dynamic inversion technique is applied to the overhead crane model to design suitable (position or velocity) set-point and torque feedforward signals. The inversion approach is further simplified in order to make the proposed methodology more industrial-oriented. Experimental results, obtained by using a scaled overhead crane built by using only off-the-shelf components, show the effectiveness of the proposed methodology.

In this work, a practical evaluation of the filtering method for weighing system is provided. The analyzed system form a part of the horticultural fruits sorting machine, which requires a fast and reliable weight measurements. Dynamic weighing of moving objects requires fast and adaptive signal processing techniques in order to guaranty a timely response. Thus, applied signal filtration technique must ensure that the constant component remains free of noise, transient responses of load cell as well as mechanical vibrations. In this paper fast nonstationary filtering method is applied, providing optimal tradeoff between response time and settling time of steady state value. The implementation method uses the distributed approach, where an intelligent sensor captures raw signal and applies adaptive filter. Subsequently, obtained value is transmitted to central unit, that applies weight compensation function to improve the measurement accuracy. All presented results use the real signal acquired in industrial conditions from the tests of sorting machine prototype. The analyzed approach obtains promising results for all sorting modes. Moreover, classical filtering approach is used for comparison purposes and performance evaluation.
本文对称重系统的滤波方法进行了实际评价。所分析的系统是园艺水果分选机的一部分,需要快速可靠的重量测量。运动物体的动态称重需要快速和自适应的信号处理技术,以保证及时的响应。因此,应用信号过滤技术必须确保恒定分量不受噪声、传感器瞬态响应和机械振动的影响。本文采用快速非平稳滤波方法,在稳态值的响应时间和稳定时间之间进行了最优权衡。实现方法采用分布式方法,智能传感器捕获原始信号并应用自适应滤波。然后,将得到的值传输到中心单元,中心单元应用权重补偿功能来提高测量精度。所给出的结果均采用了分选机样机在工业条件下测试获得的真实信号。分析的方法对所有的排序模式都得到了令人满意的结果。此外,采用经典滤波方法进行比较和性能评估。

During the past few years, with the fast development and proliferation of the Internet of Things (IoT), many application areas have started to exploit this new computing paradigm. An interesting use of IoT is in the Industrial field, which has resulted in a new business concept called IIoT (Industrial Internet of Things). Another important fact is the number of active computing devices has been growing at a rapid pace in IoT environments around the world. Consequently, a mechanism to deal with this different devices has become necessary. Middleware systems solutions for IoT have been developed in both research and industrial environments to supply this need. However, discover, search, select, and interact with devices remain a critical challenge. In this paper we present COBASEN, a software framework composed of a Context Module and a Search Engine to address the research challenge regarding the discovery and interaction with IoT devices when large number of devices with overlapping and sometimes redundant functionality are available in IoT middleware systems. The search engine of the COBASEN operates based on the semantic characteristics of the devices, which is provided by the context module, and that helps users in their interactions with desired devices. The main goal of this work is to highlight the importance of a context-based search engine in the IoT paradigm and to provide a solution that addresses the proper management of search and usage in IoT middleware environments. We developed a tool that implements all COBASEN concepts. However, for preliminarily tests, we made a functional evaluation of the search engine in terms of performance for indexing and querying response time. Our initial findings suggest that COBASEN provides important approaches that facilitate the development of IIoT applications, which based on the COBASEN systems support, may perform essential roles to improve industrial processes.
在过去的几年中,随着物联网(IoT)的快速发展和扩散,许多应用领域已经开始利用这种新的计算范式。物联网的一个有趣应用是在工业领域,它产生了一个名为IIoT(工业物联网)的新商业概念。另一个重要的事实是,在世界各地的物联网环境中,活跃计算设备的数量一直在快速增长。因此,必须有一种机制来处理这种不同的设备。物联网的中间件系统解决方案已经在研究和工业环境中开发,以满足这一需求。然而,发现、搜索、选择和与设备交互仍然是一个关键的挑战。在本文中,我们提出了COBASEN,这是一个由上下文模块和搜索引擎组成的软件框架,用于解决当物联网中间件系统中存在大量具有重叠和有时冗余功能的设备时,有关发现和与物联网设备交互的研究挑战。COBASEN的搜索引擎基于设备的语义特征进行操作,这些特征由上下文模块提供,可以帮助用户与所需设备进行交互。这项工作的主要目标是强调基于上下文的搜索引擎在物联网范例中的重要性,并提供一个解决方案,解决物联网中间件环境中搜索和使用的适当管理。我们开发了一个实现所有COBASEN概念的工具。但是,对于初步测试,我们从索引和查询响应时间的性能方面对搜索引擎进行了功能评估。我们的初步研究结果表明,COBASEN提供了促进工业物联网应用开发的重要方法,基于COBASEN系统支持的工业物联网应用可能在改进工业过程中发挥重要作用。

In this paper we present COBASEN, a software framework composed of a Context Module and a Search Engine to address the research challenge regarding the discovery and interaction with IoT devices when large number of devices with overlapping and sometimes redundant functionality are available in IoT middleware systems. The search engine of the COBASEN operates based on the semantic characteristics of the devices, which is provided by the context module, and that helps users in their interactions with desired devices. The main goal of this work is to highlight the importance of a context-based search engine in the IoT paradigm and to provide a solution that addresses the proper management of search and usage in IoT middleware environments. We developed a tool that implements all COBASEN concepts. However, for preliminarily tests, we made a functional evaluation of the search engine in terms of performance for indexing and querying response time. Our initial findings suggest that COBASEN provides important approaches that facilitate the development of IIoT applications, which based on the COBASEN systems support, may perform essential roles to improve industrial processes.","PeriodicalId":6862,"journal":{"name":"2015 IEEE 20th Conference on Emerging Technologies & Factory Automation (ETFA)","volume":"324 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2015-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76350236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2011 Ericsson and Cisco estimated 50 billion Internet connected devices by 2020, encouraged by this industry is developing application frameworks to scale the Internet of Things. This paper presents a survey of commercial frameworks and platforms designed for developing and running Internet of Things applications. The survey covers frameworks supported by big players in the software and electronics industries. The frameworks are evaluated against criteria such as architectural approach, industry support, standards based protocols and interoperability, security, hardware requirements, governance and support for rapid application development. There is a multitude of frameworks available and here a total 17 frameworks and platforms are considered. The intention of this paper is to present recent developments in commercial IoT frameworks and furthermore, identify trends in the current design of frameworks for the Internet of Things; enabling massively connected cyber physical systems.
