Web-enabled Intelligent System for Continuous Sensor Data Processing and Visualization
A large number of sensors deployed in recent years in various setups and
their data is readily available in dedicated databases or in the cloud. Of
particular interest is real-time data processing and 3D visualization in
web-based user interfaces that facilitate spatial information understanding and
sharing, hence helping the decision making process for all the parties
involved. In this research, we provide a prototype system for near real-time,
continuous X3D-based visualization of processed sensor data for two significant
applications: thermal monitoring for residential/commercial buildings and
nitrogen cycle monitoring in water beds for aquaponics systems. As sensors are
sparsely placed, in each application, where they collect data for large periods
(of up to one year), we employ a Finite Differences Method and a Neural
Networks model to approximate data distribution in the entire volume
Web3D Graphics Enabled Through Sensor Networks for Cost-Effective Assessment and Management of Energy Efficiency in Buildings
The past decade has seen the advent of numerous building energy efficiency visualization and simulation systems; however, most of them rely on theoretical thermal models to suggest building structural design for new constructions and modifications for existing ones. Sustainable methods of construction have made tremendous progress. The example of the German Energy-Plus-House technology uses a combination of (almost) zero-carbon passive heating technologies. A web-enabled X3D visualization and simulation system coupled with a cost-effective set of temperature/humidity sensors can provide valuable insights into building design, materials and construction that can lead to significant energy savings and an improved thermal comfort for residents, resulting in superior building energy efficiency. A cost-effective hardware-software prototype system is proposed in this paper that can provide real-time data driven visualization or offline simulation of 3D thermal maps for residential and/or commercial buildings on the Web
