Abstract
The article considers the model and method of converged computing and storage to create SCADA systems based on wireless networks for the energy industry. Computing power of modern wireless sensor network nodes allow the transfer to them some operations sensor data mining and offload the dispatching data centre servers. This fog computing model is used for the aggregation of primary data, forecast trends controlled variables as well as to warn about abnormal and emergency situations on distributed SCADA systems objects. Large arrays of sensor data, integral indicators and heterogeneous information from other sources (e.g., weather stations, security and fire alarm systems, video surveillance systems, etc.) is more appropriate to process via GRID computing model. GRID computing model has three-tier architecture, which includes the main server at the first level, a cluster of servers at the second level, and a lot of GPU video card with support for Compute Unified Device Architecture at the third level. The model of cloud computing and cloud storage today is the basis for the accumulation of the results of data mining and knowledge discovery. Means of communication and remote access can solve the problem of intellectual processing and visualization of information with elements of augmented reality and geo-information technologies within the framework of mobile computing model. The implementation of these four computing models for the operation of components of SCADA system is the convergent approach to distributed sensor data processing, which is discussed in the article.
Highlights
Sensor data is one of the big data, and its intelligent management and utilization have necessarily required
Sci. (2017) 7:11 decisions depend upon the following factors: timeliness obtain information about controlled objects and processes; completeness and objectivity of the analysis of this information; clarity of presentation processing results for decision support systems [5]
The research towards the synthesis and implementation of converged computing model led to the following conclusions: 1. Convergent approach to distributed computing is the convergence of distributed data processing technologies (GRID, cloudy, foggy, and mobile computing)
Summary
Sensor data is one of the big data, and its intelligent management and utilization have necessarily required. The ubiquitous introduction of automated process control systems highlights the need to collect and process a large volume of telemetry (sensor) data from a multitude of sensors, which are located at the monitoring objects [1, 2] This data is essential for the analysis/forecasting the condition and functioning objects, processes and technogenic and natural events [3, 4]. (2017) 7:11 decisions depend upon the following factors: timeliness obtain information about controlled objects and processes; completeness and objectivity of the analysis (processing) of this information; clarity of presentation processing results for decision support systems [5]. The aim of the article is an attempt to eliminate this disadvantage
