Abstract
Ocean observing in global and regional scaleis an important part of Internet of Things. Traditionalvirtual instruments have their limitations when applied inocean observing, resulting in poor data usability and lowdevelopment efficiency. In this paper, the complex virtualinstruments with enhanced capabilities for ocean observingis introduced to realize cost-efficient developments, in whichthe objects related to ocean observing are managed uniformly,the common functions that can be reused are providedand the configuration that enable code reuse and visualdevelopments are presented. Furthermore, the concept ofcomposition model of complex virtual instrument for oceanobserving is proposed, in which complex virtual instrumentsthat act as four roles can be interconnected by use of threeoperations. With the assistance of the composition model,the observation data of different observing systems can beexchanged and shared in multiple ways and the developmentefficiency of processing software is improved. The modelhas been applied to practical developments to validate itsfeasibility and effectiveness.
