Vehicles are currently being developed and sold with increasing levels of connectivity and automation. As with all networked computing devices, increased connectivity often results in a heightened risk of a cyber security attack. Furthermore, increased automation exacerbates any risk by increasing the opportunities for the adversary to implement a successful attack. In this paper, a large volume of...
Shorter innovation cycles along with the demand for individualized, high-quality products pose high challenges on today's automated material flow systems. These systems, suitable for producing bulk goods, but inflexible in case of product changes, need to react flexibly to unplanned configurations. Especially in the software domain retroactive adaptations are tedious work and prone to errors. By deploying...
Modern mechanical engineering systems are primarily designed to perform a specific system process in an optimal manner. For this purpose, they use control systems that monitor and influence the process with the help of sensors and actuators. Changing control values or (physical) disturbances are recorded and considered by the control systems. Problems arise whenever the disturbances are not physical,...
Programmable logic controllers are widely used for the control of automation systems. The standard IEC 61131-3 defines the execution model as well as the programming languages for such systems. Nowadays, actuators and sensors connect to the programmable logic controller via automation buses. While such buses, as well as the sensors and actuators, become more and more powerful, a shift away from the...
This paper addresses software design for cyber-physical automation systems that enables invariant properties of the physical system in case of software reallocation to different hardware. The proposed approach is based on the distributed reference architecture of IEC 61499 standard enhanced with a time-stamping mechanism. It is demonstrated that the proposed approach complements the abilities of IEC...
The technique of virtualization and cloud computing to manage system functionality and resources regardless of their physical locations is changing the way businesses and users interact with IT resources. Although several commercially available virtualization solutions already exist in the market, both for server and embedded real-time based systems, the deployment of virtualization and cloud-based...
This paper describes an agent-based architecture for domotics. This architecture is based on requirements about expandability and hardware independence. The heart of the system is a multi-agent system. This system is distributed over several platforms to open the possibility to tie the agents directly to the actuators, sensors and devices involved. This way a level of abstraction is created and all...
The power management technique using complete analog design interface is described in this proposed work. This project design is based on two important ideas viz. efficient management of solar energy and mechanism for changeover in case of main supply failure. The complete system mainly consists of MSP430 based power sensing device with integrated changeover mechanism. The MSP430 is connected to the...
The project aims at developing a prototype boat that is capable of autonomously sailing and navigating its way through obstacles present around it. Apart from moving on a pre defined path the boat can intelligently avoid obstacles in the path through its ability of decision making using fuzzy logic. Calculations of fuzzy logic as well as deciding inputs for the path direction to be sent to the micro...
This paper describes an agent-based software infrastructure for agile industrial production. This production is done on special devices called equiplets. A grid of these equiplets connected by a fast network is capable of producing a variety of different products in parallel. The multi-agent-based underlying systems uses two kinds of agents: an agent representing the product and an agent representing...
Embedded systems are becoming of great interest in the medical field. With the reduction of size and increase in processing power, small devices capable of capturing patient data and making control decisions may help in providing patients with better treatments. This paper describes an embedded platform that may be used for the automation of medical devices. A description is given of the hardware...
To succeed on the ever-changing conditions on the global market, companies are required to rely on flexible production systems. This applies to numerous domains including batch process automation that relies on flexible multipurpose facilities. In this paper we introduce an agent-based approach for batch process automation showing an architecture for a multi-agent system that provides such flexibility...
Nowadays, one important goal of automation is to optimize the complete work and material flow under the constraints of energy consumption, quality and throughput. As a matter of fact, the whole control process should be flexible and reconfigurable which targets the three levels of the control pyramid (ERP, MES, Field). In the context of our ongoing research project LK3S an agent platform is under...
This paper presents some intermediate results of a research project regarding with auto-guided vehicles (AGVs) and vision-based guidance. The paper describes three different degrees of autonomy, form the basic one to the full autonomous one. In particular, the paper focuses on the intermediate degree of autonomy, named as ??guided?? driving, which includes several types of application under the same...
