Integration Of Building Automation Systems Research Articles

Modeling framework for IoT integration of building automation systems

Abstract Advancements within the Internet of Things are leading to a pervasive integration of different domains including also building automation systems. As a result, device functionality becomes available to a wide range of applications and users outside of the building automation domain. In this context, Web services are identified as suitable solution for machine-to-machine communication. However, a major requirement to provide necessary interoperability is the consideration of underlying semantics. Thus, this work presents a universal framework for tag-based semantic modeling and seamless integration of building automation systems via Web service-based technologies. Using the example of the KNX Web services specification, the applicability of this approach is pointed out.

Integrating Building Automation Systems based on Web Services

It is of great advantage to integrate building automation systems (BAS) in intelligent buildings using networks (LAN or WAN).This paper addresses three technical issues in the integration of BASs. One is the integration between BASs and existing enterprise applications. The second is the integration of BASs which adopt different international standardized protocols. The third is the integration of building automation subsystems. The “intelligence” of intelligent buildings is still more of a promise than a reality. As a new generation of Internet communication technologies, Web Services are becoming an increasingly popular middleware technology, which provides new solutions to overcome above problems. The paper analyses the development history and current problems of the BAS industry, proposes that Web Services based on XML, SOAP, WSDL and UDDI are the best answer in solving the integration problems of BASs. The framework model and realization principles of BAS based on Web Services are also described. The technologies have been used to develop a building management system (BMS) for a real intelligent building successfully.

Is IP everywhere the way ahead for building automation?

Conventional wisdom suggests that the complete integration of building automation systems is the final outcome in the evolution of intelligent buildings. Security systems, energy management systems, fire alarm systems are some of the automation systems that are converging to produce a single integrated environment for building automation. These systems can execute global strategies so that the building is able to function in harmony. But one question is starting to emerge from this seemingly inevitable convergence. Is the consolidation of a single building automation protocol actually precluding possibilities for communication beyond the building automation sphere? The organic nature of the modern built environment requires cooperation between organizational activities, means of production and the facility itself. This process of integration cannot be achieved whilst the building operation is seen to be independent from other communication and control systems. Argues that the process of integrating building systems may in fact isolate such systems from a much broader range of information technology systems. Describes the use of embedded Web servers, an area where open integration might be developed. Divergence rather than convergence appears to be the future for building automation systems.
