“…The inspection of road tunnels routinely requires human operators or robots [9], who identify problems visually or by using specific equipment. A concern is the economic impact of closing the tunnel for inspection.…”

“…For example , at the entrance of a tunnel the ambient light conditions are different than further in the tunnel. The data collected by sensors in these deployments may not provide enough information for a complete assessment of the tunnel condition [9]. Thus, node and operating environment heterogeneity would benefit from decentralized data processing [11].…”

We present how NFC transponders can be used for energy efficient programming of closed-loop sensor networks, to update or augment the existing functionality. Use cases include road tunnel inspection, water pipeline monitoring and maintaining safety information on behalf of mine workers. We utilize opportunistic movement of the human operator, the flow of fluid in a pipeline or material in mines, to move the NFC transponder in the system effortlessly and without external network connectivity. Transponders contain mobile agents in their memory, which are injected into the system when transponder comes to the proximity of a node with NFC reader component. Then mobile agents autonomously operate their tasks, i.e. collect and process sensor data in the devices, detect events from data, control physical components and report their results. Mobile agents can adapt to the operational conditions of the system and physical environment, e.g. to save energy or o p era te in i so la t ed n etw o rk seg m en ts in fa u l t s it u a t io n s. Real-world evaluation shows that this method is energy efficient in comparison with communications atop similar wireless sensor network.

We introduce a low-cost robotic system designed to enable the safe, objective and efficient visual inspection of tunnels. The system captures high resolution images and processes them to produce maps of tunnel linings that are suitable for detailed inspection.It is unique in that the total cost of hardware is an order of magnitude less than most existing systems while producing an equivalent or higher quality of output. The device makes use of consumer-grade digital cameras and high-power LEDs in a rotating rig, carried by a lightweight aluminium frame which is designed to reduce vibrations during data capture. It is portable and installable by hand and has a modular design, making it possible to adapt to different types of carriage units, tunnels and sensors.Within the paper, we share insight into features of the device's design, including lessons learned from trials of earlier prototypes and comparisons with alternative systems. Using field data gathered from a 2km utility tunnel, we demonstrate the use of our system as a means of visualising tunnel conditions through image mosaicing, cataloguing tunnel segments using barcode detection and improving the objectivity of visual condition surveys over time by the detection of sub-mm crack growth.We believe that our device is the first to provide comprehensive survey-quality data at such a low cost, making it very attractive as a tool for the improved visual monitoring of tunnels.

“…When facing existing civil infrastructures, one of the greatest challenges that engineers may find is its inspection and assessment in order to to ensure that bridges, roads, pipelines and tunnels remain in safe condition and continue to provide reliable levels of service [1], [2]. The structural performance of tunnels is time-dependent because of the damaging process induced by natural and artificial impacts, inadequate maintance or the simple effect of ageing.…”
