GUARDIAN – WIRELESS SENSOR NETWORK
The Guardian platform is able to offer constant services and/or emergency monitoring services for a great number of physical parameters within different areas (temperature, displacement, landslides, inclination, air/soil humidity, etc …) The Guardian network uses a network of wireless sensors, which are made up of intelligent nodes that can detect information from the environment in which they are placed.
The Cloud Computing Software allows the collection of data coming from the various WSN Nodes. Presents a sophisticated control interface that allows:
- map with geo-location of the individual WSN nodes;
- insertion into the network of new nodes and new sensors;
- display data from single sensors;
- setting thresholds critical values;
- possibility to activate alarms on the data coming from the single sensor;
- logical concatenation (not, or, and) of individual alarms (creation of complex alarms);
- clustering of alarms (automatic grouping of alarms from homogeneous sensors distributed geographically in a certain area)
- concatenation of the various alarm clusters (creation of complex macro-alarms);
- sending alarms;
- extrapolation and history of the database data from the sensors;
- export of 1st level data (row data sensors) and 2nd level data (alarm data sensors);
- data export to additional Cloud Computing;
A node is an electronic system that acquires data from any of the above sensors and transmits data over the network. It collects data in real time from the field of application.
- power supply with rechargeable battery
- power supply from external photovoltaic panel
- autonomy greater than 5 years
- remote reprogramming of the node
- low consumption in standby mode (deep sleep mode)
- possibility of power supply in POE (power over ethernet)
THREAT OF EARTHQUAKE
They can be connected directly to the acquisition node or have a sub-ghz connection (433 MHz or 866 MHz). It can be connected different types of sensors, analog or digital (SPI or I2C bus interface), voltage (+ 3.3V, + 5V, + 9V) or 4-20mA current, 2 to 3 or 4 wires (with or without integrated Weathstone bridge).
- power supply not continuous: with the addition of photovoltaic panels each node is able to self-feed and can directly power the sensors connected to it.
- Speed-Installation: The installation of the system takes place in a very short time, and already after 24 hours it is possible to obtain important data for the planning of emergency interventions.
- Not required communication network: It can operate in the absence of electricity because it is based on free ISM frequencies and can be easily integrated with professional communication networks
- Low consumption: Each node is equipped with a low-consumption system, a solar panel cogeneration system and consumption reduction policies.
- Constant monitoring and transmission of data
- Software Monitoring
- Cloud system
It is a platform that uses weather sensors and other more specific (such as piezometers, strain gauges, rain gauges, tilt meters, inclinometer probes ..). When the pre-set threshold is exceeded, the platform activates the “red” signal of the traffic light positioned near the area under control:
- Notice to people who are nearby
- Notice to the competent authorities
The platform uses the innovative technology of the thermal imaging camera, which is the most suitable method for monitoring and fire alarms because it is able to measure the component necessary to trigger the fire: heat. The camera can be seen as an aggregation of infrared sensors: each pixel acts as an infrared sensor for measuring heat. Data from the camera is processed by software that will create 3D mathematical models that correspond to the temperature levels read.
It can be added a wireless sensor network able to track variations in temperature, humidity and carbon dioxide in the monitored areas.
The primary objective of this system is to preserve the historical-environmental heritage, thus monitoring relevant structures, declared World Heritage Sites by UNESCO.
- It is an entirely wireless solution;
- It is based on ultra-compact devices with low- impact visual and environmental.
- It has humidity and temperature detect sensors;
- It is able to supply seven additional external sensors to measure air currents, luminosity, atmospheric pressure and structural vibrations of the building.
Landfills are constantly evolving areas and must be controlled from construction to management after closure by standard controls. With the Wireless Digital Landfills system it is possible to detect data such as:
- management processes of landfill plants;
- fumes and fires on the waste crop front;
Volcanic eruptions occur when the magma, coming from the Earth, escapes to the earth’s surface. An eruption can be defined according to its degree of violence that falls within a scale called “Volcanic Explosive Index” (IEV) of different parameters. It is possible to provide volcanic eruptions, dangerous gas emissions, ash clouds and dust and relative seismic activity, by monitoring these phenomena:
- • Gas detection sensors: to control changes in the release of certain gases.
- Seismic swarm detection sensors: to detect the increase in seismic activity.
- Temperature sensing sensors: to control a variation of heat in the ground and in the water.
- Tilt meters and strain gages: installed near landslides to monitor their movement.
- Piezometric probe: to monitor pressure and water level in groundwater.
Also in this case the Guardian system will send data to the server every 15 minutes (at the choice of technicians), and these can be viewed via the web, through any smartphone or remote PC.
