ProEsys - Model IVMS-SAT -Inclination and Vibration Monitoring Sensor

The IVMS-SAT (Inclination and vibration monitoring sensor) is ideal for monitoring the structural health and integrity of critical infrastructures. It can accurately detect changes in the inclination and/or vibration (including intentional tampering) in any kind of vertical structure, such as Telco towers, HV pylons, bridges, and natural assets such as trees and embankments. Thanks to its dual satellite and terrestrial bi-directional communication system, it can be deployed even in those areas that are not covered by terrestrial networks. Its photovoltaic panel and secondary multi-year battery guarantee low maintenance costs; in addition, there is virtually no need to send in technicians for firmware or parameter updates because those can be carried out remotely (FUOTA).
The device is completely waterproof and it can be mounted without any need for terrestrial infrastructures. A very low-power inertial sensor and a high-accuracy inclinometer measure static position in real-time, detecting any change in orientation or inclination, movement, and vibration. It is possible to add modules to measure humidity and wind, allowing the detection of floods in proximity of the monitored structures.

• Unattended and long-term monitoring of verticality, vibration, intentional tampering, and earth movements allowing for early landslide alerts.
• Cooperative terrestrial and satellite communication system enabling bi-directional and real-time transmission.
• Suitable for long-range coverage of areas normally not covered by GSM, LTE, NB-IoT, and 5G.
• In satellite communication mode, no gateway or other infrastructure is required.
• Solution based on LoRa® technologies and LoRaWAN®-compatible protocols.
• Easy integration with existing terrestrial network.
• Use of ultra-efficient integrated antenna with no pointing required.
• Wireless and energy-efficient solution with photovoltaic power supply and battery life extension.
• The system ensures a high level of cybersecurity within the entire signal chain due to the encryption of messages.
• Access to collected data via a dedicated web dashboard or locally via a wireless connection.
• Possibility to set system operating parameters remotely or locally, including full firmware upgrade.

MEASUREMENTS AND PROCESSING

• Real-time monitoring of inclination and vibration of any kind of vertical structure, and prompt detection of small earth movements.
• Diagnostics of excessive stress on the structure due to physical attack, sabotage, or weather conditions.
• Discrimination of periodic oscillations of the structures from intentional tampering with mechanical instruments through spectral analysis.
• Low-power inertial sensor and high-precision inclinometer to measure static position in real-time.

COMMUNICATION

• Sending early warnings over LoRaWAN®-compatible satellite or terrestrial networks for anomalies or exceeding safety thresholds.
• Bi-directional transmission. All our IoT devices integrate the technology to transmit and receive both in the S-band satellite network and terrestrial in the ISM, EU868, US915, and AU923 bands.

EQUIPMENT

• Photovoltaic-powered and battery life extender for multi-year life.
• Waterproof device supplied in IP67 enclosures for outdoors installations.
• Easy installation. Sensors can be pole mounted or attached to any kind of structure with flanges or brackets.

ADDITIONAL FEATURES

• Optional input modules for additional external digital or analog sensors such as wind, temperature, and humidity.
• On-board calculation and storage memory capabilities to log event and vibration waveforms for later retrieval and in-deep analysis.

IVMS-SAT sensors are designed for the following applications:

• Structural health monitoring (SHM) of critical infrastructures.
• Monitoring of transmission, cellular or Telco towers.
• Monitoring of bridges and road infrastructure.
• Monitoring of embankments (landslide prevention).
