Real-time damage localization by means of MEMS sensors and use of wireless data transmission

摘要

When lifeline systems such as water delivery networks are damaged, it is critical to pinpoint the location of the damage, to assess the extent of the damage, and to mitigate the damage in real-time. We propose a wireless sensor network consisting of densely populated, optimally located MEMS sensors that monitor pipe pressure and transmitting data wirelessly. Transient analysis of water pressure in the networked pipes showed that the damage sustained by the pipe creates a state of transient in the pipe pressure, which is detectable by MEMS sensors for damage localization and estimation. This is critical information to enhance post-event disaster mitigation.
