The heart of the system comprises P5-LVL nodes, which, thanks to the presence of a PIR sensor, allow detecting the presence of people inside a room.
The nodes, connected to the electrical network by means of a Zhaga receptacle and related power supply unit, have been located on the ceiling or, in cases of particular rooms with architectural constraints, on the wall.
In smalla and medium sized room one node, properly placed, was sufficient while in larger rooms, such as corridors or gyms, more nodes have been placed. In this case, the nodes of a room are grouped into a logical unit.
The P5-LVL nodes themselves, by means of the built-in luxmeter, are able to detect the level of brightness in the room and, when a presence is detected, send a power-on command to the lights via the DALI bus.
The P5-TWT temperature/humidity sensors were then installed, which wirelessly communicate the information to the P5-LVL node. The P5-LVL can control the P5-IOV sensors installed in each fan convector via the 2.4GHz
IEEE 802.15.4 standard. In the rooms with radiators, third-party wireless valves have been installed, which are again controlled by the P5-LVL node using the EnOcean 868MHz protocol.
The data collected by the P5-LVL is sent via the IEEE 802.15.4 standard to the RIO-ETH gateways, located one per floor. The gateways of a single building
are connected via Ethernet to a router that communicates via a cellular connection with the Auge-G4 SW platform installed on the customer server.
The SW platform allows the user to remotely define temperature and brightness
setpoints for each remote controlled room, as well as send any other operating parameters. With the data collected, the SW elaborate statistics and reports on consumption and functioning status.
The platform is also equipped with a control module that detects any malfunctioning of the main components, such as boiler pumps or nodes. In order to give more precise information, specific synoptic displays have been developed for all the floors of the different buildings with the location of the lights, pumps, fan convectors and other relevant components highlighted to access each component’s specific data.
