• Data acquisition options include one-, four-, and eight-channel vibrating-wire modules, multi-channel RS485 acquisition, and 4G/NB-IoT IoT terminals for centralized or distributed automated monitoring.

Implementation and Typical Applications

• Deep-excavation and shield-shaft solutions can integrate retaining-wall deformation, deep horizontal displacement, ground and building settlement, pipeline movement, strut and anchor loads, groundwater level, and pore pressure.

• Tunnel, railway, bridge, building, and pipeline solutions can combine settlement, alignment, crack, tilt, vibration, displacement, stress, and strain monitoring.

• Slope, embankment, dam, reservoir, and tailings-facility solutions can combine deformation, soil pressure, groundwater, pore pressure, seepage, and rainfall monitoring.

• Distributed monitoring points can use local caching, breakpoint retransmission, electrical isolation, software and hardware watchdogs, and remote configuration where power supply or network connectivity is intermittent.

• Automated measurements can be combined with mobile inspection, manual monitoring, photographs, video, and construction-condition records on the same project data chain.
