Component Oriented Software Framework for Train Car Systems

Many kinds of devices are now installed in train cars. The bandwidths on train networks are also becoming very large and computerized systems are able to dynamically adjust themselves to changes in the cars´ structure. We propose a new software framework for management machines used in trains that improves flexibility, scalability and productivity. It features two hierarchical layers in which the software components are divided into device dependent or independent. Another feature is that it has a skeleton framework that provides workflow management for the components and logical data management for all cars. Based on our evaluation using a prototype system, the proposed framework is sufficient to meet the performance requirements and contribute to software productivity
