DYNAMIC WIRELESS SENSOR NETWORKS FOR REAL
TIME SAFEGUARD OF WORKERS EXPOSED TO PHYSICAL
AGENTS IN CONSTRUCTIONS SITES
Our proposed system introduces a wireless sensor network platform specifically
designed for the protection of workers employed in the building sector, exposed to
critical physical agents, typical of their working scenario. The network configuration
makes use of either a standard Bluetooth communication scheme, or a more versatile
ad-hoc set-up, which narrows the necessary transmission bandwidth and lowers the
frequency of the carriers.
The relevant part of the project activity has been concentrated on the design and
realization of a compact, wearable, washable, ergonomic, low cost wireless sensor node,
suitable to detect a huge variety of physical phenomena. The sample proposed project
has been specifically developed to measure two different kinds of exposure, Ultra Violet
rays and dust. Both these agents, for different reasons, represent a critical factors and a
certified source of possible diseases. The sensor node is embedded on the worker
garment: the electronic components are sewed on the cloth, and the antenna is
integrated within the fabric, and, together with the fabric, forms a unique structure.
Preliminary results, obtained with a non-optimized and non compact node, testify the
validity of the approach and its applicability to real cases.
