Both information and automated production systems (aPS) evolve during their lifetime, e.g. due to changes in requirements and infrastructure. In order to estimate maintenance effort in information systems the KAMP method is applied. This paper discusses the necessary classification of changes as a prerequisite to apply such a method. Aggravating aPS consist not only of software but also include mechanics and electric/automation hardware. Therefore, the classification has to be enlarged to a multi-disciplinary one. The limitations of this approach for aPS are discussed in detail and demonstrated using three scenarios of a lab size pick and place unit. The paper closes delivering first ideas to cope with these.
信息和自动化生产系统(ap)在其生命周期中都在发展,例如,由于需求和基础结构的变化。为了估计信息系统的维护工作量,应用了KAMP方法。本文讨论了作为应用这种方法的先决条件的必要的变化分类。严重的ap不仅包括软件,还包括机械和电气/自动化硬件。因此,分类必须扩大到多学科分类。详细讨论了这种方法对ap的局限性,并使用实验室大小的拾取和放置单元的三种场景进行了演示。本文最后提出了应对这些问题的初步想法。

In this work, a modified version of a Slope Statistic Profile (SSP) method is proposed, capable to detect real-time incidents that occur in two interdependent time series. The estimation of incident time point is based on the combination of their linear trend profiles test statistics, computed on a consecutive overlapping data window. Furthermore, the proposed method uses a self-adaptive sliding data window. The adaptation of the size of the sliding data window is based on real-time classification of the linear trend profiles in constant and equal time intervals, according to two different linear trend scenarios, suitably adjusted to the conditions of the problem we face. The proposed method is used for the robust identification of a malfunction and it is demonstrated to real datasets from a chemical process pilot plant that is situated at the premises of CERTH / CPERI during the evolution of the performed experiments at the process unit.
在这项工作中,提出了斜率统计剖面(SSP)方法的改进版本,能够检测在两个相互依赖的时间序列中发生的实时事件。事件时间点的估计是基于它们的线性趋势曲线的组合,在一个连续的重叠数据窗口上计算检验统计量。此外,该方法采用自适应滑动数据窗口。滑动数据窗口大小的自适应是基于恒定和等时间间隔的线性趋势曲线的实时分类,根据两种不同的线性趋势情景,根据我们所面临的问题的条件进行适当调整。所提出的方法用于故障的鲁棒识别,并在过程单元进行实验的演变过程中,对位于CERTH / CPERI场所的化学过程中试工厂的真实数据集进行了演示。

A smart environment system should automatically control the devices according to the sensing information and users' requirements so as to keep the environmental elements (e.g., temperature, light) within the desired range. System control with minimum power is one key issue in such a system. In this paper, we propose a multi-dimension model for system control. In this model, each environmental element is abstracted into a dimension, such that a service with conditions and targets can be formulated as a multi-dimensional service space, and a smart environment with many services may map to a comprehensive multi-dimensional service space through space computation. Based on this model, we propose a minimum power adjustment algorithm for energy-efficient scheduling in smart environment, which transforms the optimal control problem into the problem of the shortest weighted distance of point-to-polygonal in multi-dimensional space. Theoretical analysis and experimental results show that the proposed model is effective and efficient in energy-efficient system control. It is important to point out that the proposed algorithms are scalable when the number of dimensions or services increases.
智能环境系统应根据感知信息和用户要求自动控制设备,使环境要素(如温度、光线)保持在期望的范围内。最小功率控制是该系统的关键问题之一。本文提出了一种用于系统控制的多维模型。该模型将每个环境要素抽象为一个维度,从而将具有条件和目标的服务公式化为多维服务空间,将具有众多服务的智能环境通过空间计算映射为综合的多维服务空间。在此模型的基础上,提出了智能环境下节能调度的最小功率调节算法,将最优控制问题转化为多维空间中点到多边形的加权距离最短问题。理论分析和实验结果表明,该模型在节能系统控制中是有效的。重要的是要指出,当维度或服务的数量增加时,所提出的算法是可扩展的。

Object detection in images is a computing demanding task which usually needs to deal with the detection of different classes of objects, and thus requiring variations and adaptations easily provided by software solutions. Object detection algorithms are being part of real-time smarter embedded systems, such as automotive, medical, robotics and security systems. In most embedded systems, efficient implementations of object oriented algorithms need to provide high performance, low power consumption, and programmability to allow greater development flexibility. The Histogram of Oriented Gradients (HOG) is one of the most widely used algorithms for object detection in images. In this paper, we show our work towards mapping the HOG algorithm to an FPGA-based system consisting of multiple Nios II softcore processors and bearing in mind high-performance and programmability issues. We show how to reduce 19x the algorithms execution time by source to source transformations and specially avoiding redundant processing. Furthermore, we show how the use of pipelining processing using three Nios II processors allows a speedup of 49x compared to the embedded baseline application.
图像中的目标检测是一项计算要求很高的任务,通常需要处理不同类别的目标检测,因此需要软件解决方案易于提供的变化和适应。目标检测算法正在成为实时智能嵌入式系统的一部分,如汽车、医疗、机器人和安全系统。在大多数嵌入式系统中,面向对象算法的有效实现需要提供高性能、低功耗和可编程性,以允许更大的开发灵活性。定向梯度直方图(Histogram of Oriented Gradients, HOG)是目前应用最广泛的图像目标检测算法之一。在本文中,我们展示了将HOG算法映射到基于fpga的系统的工作,该系统由多个Nios II软核处理器组成,并考虑到高性能和可编程性问题。我们展示了如何通过源到源转换减少19倍的算法执行时间,特别是避免冗余处理。此外,我们还展示了如何使用三个Nios II处理器进行流水线处理,与嵌入式基线应用程序相比,它的速度提高了49倍。

A fully integrated single-band 2.4 GHz low noise amplifier (LNA) is designed by using 0.18μm CMOS technology for ZigBee applications. For healthcare applications, high power consumption is not preferred. Increasing the sensitivity of receiver, therefore, could be a solution resulting in the use of LNA. The impedance expression is mathematically reconstructed into a quadratic equation and leads to the solutions by adding the LC tank in the matching networks. Besides, by using voltage controlled MOS varactor, the LC tanks at the input and output can be tuned. Such topology is convenient for calibrating the frequency drift due to the process variation and unexpected parasitics. The amplifier works at the supply voltage 1.2 V with current dissipation 10 mA. The gains achieved are over 15 dB at 2.4 GHz and the corresponding noise figure is about 2.1 dB.
采用0.18μm CMOS技术,设计了一款适用于ZigBee应用的全集成单频段2.4 GHz低噪声放大器(LNA)。对于医疗保健应用程序,不建议使用高功耗。因此,增加接收器的灵敏度可能是导致使用LNA的解决方案。将阻抗表达式在数学上重构为二次方程,并通过在匹配网络中加入LC槽得到解。此外,利用压控MOS变容管,可以对输入输出端的LC槽进行调谐。这种拓扑结构可以方便地校正由于工艺变化和非预期寄生引起的频率漂移。放大器工作在1.2 V的电源电压下,电流损耗为10 mA。在2.4 GHz时,增益超过15 dB,噪声系数约为2.1 dB。

Output observer for fault detection in linear systems 用于线性系统故障检测的输出观测器

Fault detection (FD) is the process of monitoring a system to identify any malfunction occurring in the system. In model based fault detection, a state estimator or observer is usually designed in order to provide an estimated output which is compared with the measured output and evaluated with a decision making algorithm to identify a fault. In this paper, a new approach for fault detection is proposed based on the design of an output observer, instead of a state observer, using an input/output system representation. The proposed output observer is employed to estimate the output of the system only in order to generate a set of residuals that are indicative of the presence of a fault. The convergence of the observer is proven for any initial condition and a fault detectability condition is set. This FD scheme is validated by simulating a model of a three wheels robot.
故障检测(FD)是监视系统以识别系统中发生的任何故障的过程。在基于模型的故障检测中,通常设计一个状态估计器或观测器来提供一个估计输出,该输出与测量输出进行比较,并用决策算法进行评估以识别故障。本文提出了一种新的故障检测方法,该方法基于输出观测器的设计,而不是使用输入/输出系统表示的状态观测器。所提出的输出观测器被用来估计系统的输出,只是为了产生一组指示故障存在的残差。在任意初始条件下证明了观测器的收敛性,并设置了故障可检测性条件。通过对三轮机器人模型的仿真验证了该方案的有效性。

Holographic-laser-drawing volumetric display 全息激光绘制体积显示
Pub Date : 2016-07-01 DOI: 10.1109/INDIN.2016.7819226
K. Kumagai, Y. Hayasaki
We propose a holographic-laser-drawing volumetric display using a computer-generated hologram displayed on a liquid crystal spatial light modulator and multilayer fluorescent screen. The holographic-laser-drawing technique has enabled three things; (i) increasing the number of voxels of the volumetric graphics per unit time; (ii) increasing the total input energy to the volumetric display because the maximum energy incident at a point in the multilayer fluorescent screen is limited by the damage threshold; (iii) controlling the size, shape and spatial position of voxels. In this paper, we demonstrated (i) and (ii). The multilayer fluorescent screen was newly developed to display colored voxels. The thin layer construction of the multilayer fluorescent screen minimized the axial length of the voxels. A two-color volumetric display with blue-green voxels and red voxels were demonstrated.

The rapid development and employment of new technologies in the industrial domain forces enterprises dynamically adapting to changes. For example, supply chain enterprises' networks need to adopt affordable and fast responsive information systems, which must be also compatible with other systems for exchanging data. The ongoing Cloud Collaborative Manufacturing Networks (C2NET) project aims the development of a cloud-based platform to enable collaboration and optimization of processes that are performed in supply chains. The C2NET approach will allow collaborative networks (CNs) to improve the efficiency of organizations working in the same value chain. One important aspect of CNs is the interaction of users with the information needed for performing different tasks in the supply chain. The way in which the information is presented, is critical for users to be more efficient in their duties. Thus, user interfaces (UIs) must be customized in order to display useful information depending on the UI user. This research work focuses on a part of the C2NET project that intends to display in devices and web browser friendly UIs which are automatically adapted to the type of user or the role of the enterprise's worker. This article presents an implementation of an industrial visualization ontological model that might be employed for the C2NET platform. The result is a mobile application that provides an adaptive interface, which dynamically changes depending on the user and the notifications received from the CNs systems.
工业领域新技术的快速发展和应用迫使企业动态适应变化。例如,供应链企业的网络需要采用价格合理且响应迅速的信息系统,这些系统还必须与其他系统兼容以交换数据。正在进行的云协同制造网络(C2NET)项目旨在开发基于云的平台,以实现供应链中执行的流程的协作和优化。C2NET方法将允许协作网络(CNs)提高在同一价值链中工作的组织的效率。神经网络的一个重要方面是用户与执行供应链中不同任务所需的信息的交互。信息呈现的方式对于用户更有效地履行职责至关重要。因此,必须定制用户界面,以便根据UI用户显示有用的信息。这项研究工作的重点是C2NET项目的一部分,该项目打算在设备和web浏览器中显示友好的ui,这些ui可以自动适应用户类型或企业工作人员的角色。本文提出了一个可用于C2NET平台的工业可视化本体论模型的实现。其结果是一个提供自适应界面的移动应用程序,它根据用户和从CNs系统收到的通知动态变化。

For example, supply chain enterprises' networks need to adopt affordable and fast responsive information systems, which must be also compatible with other systems for exchanging data. The ongoing Cloud Collaborative Manufacturing Networks (C2NET) project aims the development of a cloud-based platform to enable collaboration and optimization of processes that are performed in supply chains. The C2NET approach will allow collaborative networks (CNs) to improve the efficiency of organizations working in the same value chain.
