Wireless monitoring using tilt meter and other sensors is an exception. Sampling and reporting frequency
can be set to sub-minute intervals (although this will reduce the battery life of the system). Innovative solutions such as Senceive InfraGuard™ combine long-life with a high probability of event detection by using unique responsive sensors that can “wake up” from a low power mode to a near continuous mode if movement is detected. Rapid sampling is important in applications where things can change quickly. Examples include monitoring:
• tunnel convergence in the hours following lining construction
• structures such as building facades affected by adjacent demolition or construction works
• bridges and structures considered vulnerable to flood or impact damage slopes such as railway cuttings and flood banks.
Key considerations: Rapid sampling improves the probability of event detection – but usually comes with the payoff of short battery life
The intelligence built into InfraGuard sensors enables unique responsive behaviour AND ultra-long battery life
Long-term continuous monitoring provides a potentially powerful database to enable asset owners to characterise cyclic patterns of behaviour and identify problems in time to act – potentially the basis of predict and prevent maintenance.
