This work considers the problem of designing the architecture of a network management system for a generic module of a modern automated building. To improve the efficiency of building operation given the large influx of data, the architecture of the network management system implements multicontour management of a generic modules using cloud scenarios. Building operation efficiency is enhaced by using data mining blocks in the external control loop to detect the systematic behavior of users of a generic building module. This is based on data from IoT controllers, statistical processing of information on the system's server and generation of control actions in automatic and / or automated modes. As a technological base of the building management complex, a set of Internet of Things devices (IoT) is considered. The implementation of control algorithms for a typical intelligent building module is described by a software program model, for example, in the form of logical structure algorithms
Subject: smart house maintenance requires taking into account a number of factors - resource conservation, mitigating working expenditures, safety enhancement, ensuring comfort of leisure and operation. Automation of such engineering systems networks as illumination, climate control, security and communication, may be achieved through utilization of contemporary technologies (e.g. IoT – Internet of Things). However, storing and processing the overwhelmingly massive corpora of data produced by the aforementioned systems poses a significant challenge. It is necessary to rationally manage the available big data during the stage of information modelling, due to the fact, that a building’s lifespan outlives most iterations of safety, comfort, and maintenance standards substantially.
Materials and methods: since smart houses may be classified as human-machine systems, the cybernetic approach will be considered as the base method of information system design and discovery. Instrumental methods are represented by set-theoretical modelling, automata theory and architectural principles of information management systems’ organization.
Results: an agile architecture of information system for smart house hardware management has been synthesized. The architecture encompasses several levels: client level, application level and data level; as well as three layers: presentation level, actuating devices layer and analytics layer. As proposed, the problem of growing volumes of information process by realtime message controller is attended by employment of sensors with configurable thresholds and actuating mechanisms, which implement control logic based on discrete automaton (namely, logical algorithm schemes). Multicircuit control system is suggested to be additionally enhanced with datamining module, DBMS, datamarts, and OLAP cube, which are jointly capable of processing large amount of data produced by hardware subsystems.
Conclusions: an information system for smart house hardware management, once built according to the proposed architecture, will enhance the quality of decision-making process, decrease operational costs of the smart house, due to the datamining-enabled control circuit. Suggested solution is recommended to be employed for the management of buildings and constructions, that utilize means of automation and IoT.
The problem of designing a cyberphysical system used as a service for Smart buildings control using Internet technologies — Internet of Things (IoT) is considered. Such software platforms are part of the complex systems of the BEMS — Building Energy Management Systems and are an instrument for implementing energy savings in buildings. IoT servers and controllers form a management infrastructure in which the mechanisms of adaptation and data mining, which are continuously received from a large number of nodes, play a special role. In the absence of standards for the implementation of BEMS based on IoT, as well as increasing requirements for the composition and functions of analytical support, there is a need to unify software architectures and ensure their effective implementation in solving practical problems. Software component unification, including the scenario manager, provides operational software implementation using various information technologies, including cloud or foggy computing. The presented architectural templates clearly illustrate the possibilities of scaling and developing services for managing intelligent buildings using IoT. The projected open SaaS architecture software platform is an effective means for buildings energy managing with a contour of Data Mining. It can be used for replication of knowledge about the energy efficiency in buildings, including the use of renewable energy sources.
