Patterns for distributed machine control system data sharing
Marko Leppänen, Veli-Pekka Eloranta · 2012
In this paper we will present three patterns for sharing sensory data and other information in distributed machine control systems. A distributed machine control system is a software entity that is specifically designed to control a certain hardware system. This special hardware is a part of a work machine, which can be a forest harvester, a drilling machine, elevator system etc. or some process automation system. Some of the key attributes of such software systems are their close relation to the hardware, strict real-time requirements, functional safety, fault tolerance, high availability and long life cycle. Data sharing is essential part of achieving distribution as collaboration between different parts of the system requires data exchange.
