Structural Health Monitoring
When structures become smart
Structural Health Monitoring (SHM) aims to give, at every moment during the life of a structure, a diagnosis of the “state” of the constituent materials, of the different parts, and of the full assembly of these parts constituting the structure as a whole. Structural Health Monitoring combines a variety of sensing technologies with an embedded measurement controller to capture, log, and analyze real-time data. SHM systems are designed to reliably monitor and test the health and performance of structures such as the following:
• Bridges and dams
• Buildings and stadiums
• Vessels and platforms
• Airframes
• Wind turbines
The recent developments in sensor technology, especially when wireless technology is considered, have opened up new gates in terms of health monitoring and preemptive fault detection.
BeanAir®’s wireless sensor technology offers great reliability, versatility, maintainability and easy to deploy technology.
Structural Health Monitoring on Bridge
During its long service life a bridge would be subject to aging processes, harsh environmental conditions and excessive loads, leading to deterioration. Consequences of impaired physical condition can be as severe as the collapse of the structure, causing great financial loss or even casualties, but even major protective maintenance and upgrading works or replacement of the bridge are expensive and troublesome. Thus, it is important to have updated information on structural condition and performance of bridges in order to early detect any worrying signs of decline and undertake protective countermeasures. BeanAir® provides a Wireless IOT Sensors solution suitable for bridge monitoring enabling Engineering practices to monitor assets remotely without the need for costly site visits. It has also the advantage of daily data, whereas traditionally this data was collected weekly or monthly, using physical site visits. Needless to say it is far more accurate than any visual inspection.
Vibration Monitoring
The BeanDevice® Wilow® AX-3D is a ULP (Ultra-Low-Power) WIFI accelerometer with built-in data logger. This device comes with two measurement range (±2g and ±10g) and provides a maximum sampling rate of 2 KHz.
Thanks to it’s very low noise (45 µg/√Hz for the ±2g version), this device is suitable for ground vibration on construction site.
Vibration waveform, frequency spectrum (FFT) and Velocity are displayed in real-time on our monitoring software (BeanScape® Wilow® ).
The innovative measurement mode Streaming with event-trigger (S.E.T.) allows to record vibration when a trigger threshold level is reached.

Tilt Monitoring
The BeanDevice® Wilow® HI-INC a ULP (Ultra-Low-Power) WIFI inclinometer for tilt/inclination measurement.
This device comes with two measurement range (±15° and 30°) and offers a great level of accuracy of ±0.05° (±0.02° on customer request) .
This device is suitable for land surveying and bridge monitoring, user can setup alarms by email (from our BeanScape® Wilow®) when a threshold level is reached.
Extend your wireless range by deploying a multi-hop wireless network
Need to deploy a wireless sensor network on a 3 or 4 spans bridge ? No worry, you can easily extend your wireless range by deploying a multi-hop Wireless IOT Sensors.
Our Wilow® product line is compatible with WIFI Bridge/Repeater, user can connect up to 7 WIFI Repeater/Bridge with a wireless range up to 2km between each WIFI Repeater/Bridge.
Remote access to your monitoring site
Ready for IOT (Internet of things) applications, WiLow® devices integrates MQTT (Message Queuing Telemetry Transport) data frame, a lightweight and open-source Internet of Things protocol. User can quickly setup an affordable and scalable IOT application.
Our new Wilow® IOT Gateway comes with 4G connectivity and can be remotely connected to our supervision software BeanScape®.
Smart and flexible power management
Wilow® IOT sensor is compatible with both Solar energy harvesting or USB Power supply (5VDC).
