Modeling and simulation of water fountain control software in ptolemy II

Abstract

There are two methods to design software model, object-oriented and component-oriented. Embedded system has the characteristics of real-time, hierarchy and heterogeneousness. Disadvantage of object-oriented method is so much functional coupling that system's characteristics cannot be described well. Component-oriented method can meet the system's characteristics well because of components independent from each other. We introduce actor-oriented Ptolemy II modeling method, using atomic actor and composite actor by tree structure to solve hierarchy of the system, and using different computation model interaction to solve real-time heterogeneity of the system. This paper describes the principle of small water fountain control software and compares the advantages and disadvantages between component-oriented Ptolemy II platform and object-oriented UML modeling. Water fountain control software is modeled in the form of different actor-oriented components and then simulates based on Ptolemy II platform. As a result, expected result is achieved. © 2011 Springer-Verlag Berlin Heidelberg.
