How SmartSafety Works

 Complete Wireless System

SmartSafety platform requires to deploy a wireless network infrastructure in construction site. The network receives messages of wireless tags attached to workers, machines and personal protective equipments as well as sensors that provides specific measurements.
Moreover the network, by means of a coordinator/gateway (ADSL or UMTS), forwards information through Internet to the main Server application, where high level control logics are implemented and a web service interface to end users is provided.
As sites to be monitored are generally large, the use of several (expandable) sub-networks should be planned. In this case a WiFi is provided in order to connect every sub-coordinator to Internet gateway.

 

SmartSafety Hardware 

The main feature needed from a system that must be deployed all over the whole area of construction sites is that it must not interfere with workers moving around in congested and dynamic situations. Hence, it must be made up of detached devices, with no cabling neither for communication nor for powering, hence battery powered, which means also very low power consumption to come out with at least a five year long power autonomy
Ultra-low power mesh networks let us put sensors exactly where the action is, without wiring for power or communications. The sensors provide safety information 24/7 to the SmartNetwork that provides to forward data to the application server, where it feeds into SafetyView application.

 

Real Time Location System (RTLS)

SmartNetwork performs real time localization of any tagged person, equipment or asset. This allows to implement context aware logics to manage safety conditions of site. First of all the compliance of personal protection equipment is evaluated in accordance with the real situation of the area where workers arre operating.

Additional sensors

Even additional checking can be managed through the use of non invasive but low accurate monitoring systems, according to the specific features of construction sites. For example, a wireless network interfaced with several sensors, would allow acquiring in real time many health indicators (e.g. sound level, dust concentration in air) and advise H&S coordinators in case they overcome admissible thresholds.
