Bridge Monitoring with Dynamic and Static Wireless IoT Sensors

Continuous monitoring of critical parameters such as vibrations, frequencies, modal shapes, and deformation of bridges and viaducts is crucial for ensuring the safety and reliability of these structures. Early detection of any abnormalities can help engineers take corrective actions before they develop into severe problems, preventing costly repairs and potential disasters.

Advanced technologies such as accelerometers, tiltmeters, dynamic displacement sensors, and geotechnical probes can be utilized for the real-time monitoring of structural elements, such as:

Deck • Piers • Cable stays • Abutments • Joints

The Strain Gauge measures the strain or deformation of a structure, while the Single Channel Node makes the sensor suited for LoRaWAN wireless communication, sending alarms when a certain activation threshold is exceeded.

Deformation monitoring

Monitor the deformation of the deck, the beam, and of other structural elements to identify stress, and potential structural problems or degradation that could compromise the safety and longevity of the structure.

Tiltmeter

Bridge piers stability

Monitor the stability of the bridge piers and any lateral movement to identify potential structural problems that could compromise the safety of the bridge.

Dynamic Displacement Sensor

It measures small changes in the dynamic displacement or movement of structures, and it sends an alarm when a certain activation threshold is exceeded. It also monitors temperature, and it is wireless, plug-and-play and with a long-life battery.

Dynamic Displacement

Monitor deck oscillations and vibrations to prevent excessive vibration from leading to structural damage and compromising the safety and functionality of the bridge.

Accelerometer

It measures acceleration and frequency in three axes, and it can be synchronised with other Accelerometers for Modal Analysis. It also monitors temperature, and it is wireless, plug-and-play and with a long-life battery.

Stay cables frequencies

Monitor the tension and frequencies of the stay cables of a bridge to ensure that the bridge is structurally sound and can safely support the weight of vehicles and pedestrians.

Single Channel Node + Load Cells

The Load Cells monitor the weight or force, while the Single Channel Node makes the sensor suited for LoRaWAN wireless communication, sending alarms when a certain activation threshold is exceeded.

Stay cables monitoring

Monitor the tension in the stay cables and supports of a bridge to ensure that the bridge is structurally sound and that it is not at risk of collapsing or failing.

Weather Station monitoring - LoRaWAN IoT

Single Channel Node + Weather station

The Weather station records various atmospheric conditions and weather-related variables, while the Single Channel Node makes the sensors suited for LoRaWAN wireless communication, sending alarms when a certain activation threshold is exceeded.

Environmental monitoring

Monitor environmental factors such as temperature changes, humidity, wind, and precipitation to understand the impact that they can have on the health and performance of the structure.

Gateway Pro

It acts as an intermediary, using LoRaWAN communication to collect data measured by the sensors and transmitting them to the Cloud Platform where it can be processed, analyzed, and acted upon. The device is Outdoor IP67 and is powered by PoE; optionally it can be powered by battery, with solar panel.
The Gateway Pro is equipped with LoRa, LTE, GPS and Wi-Fi antennas. Thanks to the dual LTE antennas, increased cellular coverage is possible. The device also implements a Wi-Fi hotspot and a builtin GPS for very precise synchronization and geolocation of the product. It is a very easy to set up thanks to the automatic APN and the included PoE adapter.
