Sensor package
DECK - DISPLACEMENT SENSOR
The DECK device is the only patented wireless sensor on the market capable of mea-
suring the mono-axial oscillations of the structure by providing displacement values,
with an accuracy of 0.01 mm. Samples at 100 Hz, constantly and remotely. It is also
capable of detecting temperature and vibration frequency.
TRIAXIAL TITLMETER
The triaxial tilmeter is a wireless sensor capable of measuring the inclination and
the static angular variation of the structure with respect to the horizontal plane, or
perpendicular to the gravitational axis. By installing an entire system, it is possible to
reconstruct the deformation of the deck.
TRIAXIAL ACCELEROMETER SHM
The SHM triaxial accelerometer is a wireless sensor capable of measuring the acce-
leration of the point where it is installed on the three axes and at high resolution. All
installed Accelerometers can be perfectly synchronized with each other. Thanks to
this feature, it is possible to measure the Vibration Frequencies and perform a Modal
Analysis of the structure. The accelerometer also integrates a temperature sensor.
ANALOG COMMUNICATIVE NODE
The Analog Node is a device that enables all connected (originally wired) sensors
or probes for wireless communication via LoRaWAN. The Analog Node supports a
maximum of 4 sensors and is compatible with most of the analog interfaces used
for geotechnical sensors, such as: strain gauges, temperature sensors, load cells,
crack meters, humidity sensors, piezometers, anemometers, inclinometer probes,
rain gauges and radar.
GATEWAY SHM
The SHM Gateway is a communication control unit with which it is possible to receive
data from dozens of devices simultaneously via LoRaWAN. It is equipped with LoRa,
LTE, GPS and Wi-Fi antennas. It implements a Wi-Fi hotspot and a GPS for a very
precise synchronization and for the geolocation of the product. Automatic detection
of the APN.
With the Move Solutions™ monitoring system it is possible to detect and analyze the
level of stress, pressures and vibrations that any civil work or building endures over
the years. There are many monitoring solutions available, that differ based on the
structure being analyzed. Both in dynamic and static conditions, continuous monito-
ring is possible in multiple contexts, such as:
•
Bridges;
•
Viaducts;
•
Buildings;
•
Dams;
•
Construction sites and works under construction;
•
Tunnel;
•
Railways and subways;
•
Telecommunication towers.
SYSTEM OPERATION
The Move Solutions™ monitoring system consists of multiple types of wireless sen-
sors bundled with a software suite - the Move Cloud Platform™ - for displaying and
managing data and devices.
Once the wireless sensors and Gateways are correctly installed on site, the system is
ready to detect, send and store data.
The data collected can be viewed in real time thanks to the Move Cloud Platform™
provided by Move Solutions™, which allows users to remotely monitor the site of in-
terest. With the Move Cloud Platform™, the user can set different operating parame-
ters of each individual sensor, including sampling rates, resolution, alarm thresholds,
activation thresholds and much more.
The system guarantees a constant monitoring of the structure’s health and the cre-
ation of historical records of the collected data which can be accessed at any time.
