When developing video-based surveillance systems the developer faces a highly complex task due to the wide range of application domains where video-based surveillance systems are applied. As the number of domains of application increases, so does the level of variability of non-functional and functional properties that needs to be managed by video-based surveillance systems. The traditional response...
The IEC 61499 modeling language pursues a component-based approach with modular building blocks coupled by ports and arranged in a hierarchical manner. However, as in similar approaches, the IEC 61499 language does not define how functional hierarchies of upper- and lower-level functional entities should be built. In this paper, motivated by our previous work, structuring principles for IEC 61499...
Model driven engineering (MDE) technologies are seen as a potential solution to tackle increasing complexity prevailing in developing industrial control systems. Many groups are proposing MDE methods for this application area. Based on company interviews, challenges in industrial adoption of MDE processes and tools have been identified. Our research goal is to gain insight and identify challenges...
This paper proves feasibility of a fully distributed automation design of Baggage Handling Systems automation. The proposed design methodology leverages IEC 61499 Function Blocks as a supporting architecture. Each physical element of the BHS, such as a conveyor is represented by a Function Block that encapsulates functionality into a single re-usable module. The proposed solution demonstrates such...
Automation Systems Engineering projects typically depend on contributions from several engineering disciplines. While available software tools are strong in supporting each individual engineering discipline, there is very little work on engineering process management and monitoring across multi-discipline engineering projects. In this paper, we present the Engineering Cockpit, a social-network-style...
Modern control / automation applications are based on complex and large scale software system. Hence, an effective adoption of software engineering best practices is required in the automation application development lifecycle (AADLC) which often seems to be not well practiced. This paper presents a critical inspection on the state-of-the-art software engineering practices, methods, and tools used...
This paper presents two new function block types for the IEC 61499 compliant 4DIAC runtime (FORTE). The function blocks are created in an attempt to increase the possibilities of reconfiguring function block applications during operation, without having to recreate the function block networks or recompile the FORTE runtime. The first block-type is created for generic I/O, and demonstrates how a single,...
The IEC 61499 standard is targeting the enhancement of the IEC 61131–3 PLC standard in distributed automation systems improving the reconfigurability, portability and reusability of automation software. This paper proposes a foundation to a novel approach for design the system based on IEC 61499 function blocks. This design process is including design recovery, configuration, semantic analysis and...
Automated People Movers (APM) are systems for passenger transport with fully automated operation and high frequency service. Trains controllers are traditionally centralized and based on wired circuits, although they generally have serious difficulties in the installation and maintenance. As there is increased demand on the system, there are advantages in choosing an open architecture, with a simple...
IEC 61499 is an international standard for designing Industrial Process Control Systems using artefacts such as Function Blocks and Execution Control Charts. The existing approaches towards formal verification of function blocks lack the natural expression for specifying the system properties. We suggest an approach for performing formal verification of IEC 61499 designs using observers expressed...
Control applications are continuously growing in complexity due to the inclusion of new functionalities and services, which demand increasing the semantic of design elements. This sounds familiar to software engineers, who have already walked that road. Design patterns are one of the techniques they have commonly used to leverage their design semantics, considering them as reusable "trusted solutions...
Industrial automation plants are controlled essentially by PLC-based control systems. PLCs are today mostly programmed in the languages of the IEC 61131–3 standard which are not ready to meet the new challenges of widely distributed automation systems. Currently, different solutions are under development from industry and research: an extension of IEC 61131–3 which includes object oriented programming;...
In the digital product development of the automotive and aviation industries, the traditional digital mock-up (DMU) is about to be supplemented and superseded by the digital functional mock-up (DFMU). The DFMU extends the geometric integration of product models, as provided by traditional DMUs, with functional aspects. Thus, it allows investigating both physical and logic model properties. Additionally,...
Current visualization systems in industrial automation mostly rely on dedicated runtime environments making the migration of visualization solutions from one platform to another almost impossible. On the other hand, an increasing number of different platforms has to be used also in industrial automation, to monitor or to operate the technical process. We propose with Movisa a model-driven approach...
This paper presents a preliminary study towards the applications of IEC 61499 Function Block standard in distributed motion control systems, where synchronization is of crucial importance. In particular, an investigation on the possibilities of applying event-driven function blocks in the time-based motion control system has been performed on the SIDEL SL90 packaging machine's control system. To achieve...
This paper is about the conceptual design of the IT support for human rights watching, police transparency and police performance evaluation. Firstly we understand that human rights are rights that humans have by the fact of being human, and which are neither created nor can be abrogated by any governmental institution. These include cultural, economic, and political rights, such as right to life,...
Ships and naval vessels are significant expensive properties of the nation. They transport expensive goods and often contribute to country's security. They may face many critical emergency cases in sea that lead to accidents, collision, ship overturn leading to a destructive effect on life, property and environment. One of the major reasons for ship accidents is due to human error. To reduce accidents...
In this paper an approach for developing knowledge-based viral fever detection system based on the methodology of case-based reasoning (CBR) is described. CBR is an approach for solving problems based on solutions of similar past case. Cases are stored in a database of cases called a case base (CB). To solve an actual problem a notation of similarities between problems is used to retrieve similar...
Service Oriented architecture (SOA) on Mobile Ad hoc NETwork (MANET) promotes the effort to deploy the day to day business and other services over the ad hoc mobile environments. In this paper several research challenges have been summarized related to the service publishing, registration indexing, availability, discovery and composition on dynamic environment of MANET. Several general issues related...
