Abstract

Monitoring of civil infrastructures is critically needed to track aging, damages and ultimately to prevent severe failures which can endanger many lives. The ability to monitor in a continuous and fine-grained fashion the integrity of a wide variety of buildings, referred to as structural health monitoring, with low-cost, long-term and continuous measurements is essential from both an economic and a life-safety standpoint. To address these needs, we propose a low-cost wireless sensor node specifically designed to support modal analysis over extended periods of time with long-range connectivity at low power consumption. Our design uses very cost-effective MEMS accelerometers and exploits the Narrowband IoT protocol (NB-IoT) to establish long-distance connection with 4G infrastructure networks. Long-range wireless connectivity, cabling-free installation and multi-year lifetime are a unique combination of features, not available, to the best of our knowledge, in any commercial or research device. We discuss in detail the hardware architecture and power management of the node. Experimental tests demonstrate a lifetime of more than ten years with a 17000 mAh battery or completely energy-neutral operation with a small solar panel (60 mm × 120 mm). Further, we validate measurement accuracy and confirm the feasibility of modal analysis with the MEMS sensors: compared with a high-precision instrument based on a piezoelectric transducer, our sensor node achieves a maximum difference of 0.08% at a small fraction of the cost and power consumption.

  • In [4], Di Nuzzo et al. overcome the communication range issue using both LoRaWAN and NB-IoT protocols but support only a few kbps of transmission bandwidth.

    “Another SHM platform measuring vibration is proposed in [4], where Di Nuzzo et al. overcome the communication range issue using both LoRaWAN and NB-IoT protocols but supporting only a few kbps of transmission bandwidth.”

    From Aerosense: A Self-Sustainable and Long-Range Bluetooth Wireless Sensor Node for Aerodynamic and Aeroacoustic Monitoring on Wind Turbines (2023) · cites this paper as [4]

    The Related Work section (p. 3) says the system uses NB-IoT for its communication link, not both NB-IoT and LoRaWAN; it describes LoRaWAN as unsuitable for this application. The Narrowband IoT section (p. 3) gives rates of 20 kbps uplink and 200 kbps downlink, contrary to the claim that transmission is limited to only a few kbps. (LLM, conf=0.92)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Previous wireless solutions installed on wind turbines mainly included vibration measurements on the wind turbine tower for SHM monitoring purposes rather than acquiring aerodynamic data directly on the blade(s).

    “However, previous designs mainly included vibration measurements [4], [17] on the wind turbine tower for SHM monitoring purposes rather than proposing a solution capable of acquiring aerodynamic data directly on the blade(s).”

    From Aerosense: A Self-Sustainable and Long-Range Bluetooth Wireless Sensor Node for Aerodynamic and Aeroacoustic Monitoring on Wind Turbines (2023) · cites this paper as [4]

    The Introduction (p. 2) describes a wireless, MEMS-based system for vibration-based SHM, supporting that part of the citation. It specifies building modal analysis, however, and the In-Field Validation (p. 8) uses a laboratory structure simulating building behavior. The paper does not support the claim that measurements were made on a wind-turbine tower or the comparison with aerodynamic measurements on blades. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • It is crucial to design energy-efficient and reliable devices able to acquire, process and transmit data for several years and eventually for the full wind turbine lifetime, exploiting environmental sources such as small solar photovoltaic panels.

    “Thus, it is crucial to design energy-efficient and reliable devices able to acquire, process and transmit data for several years and, eventually, for the full wind turbine lifetime, exploiting environmental sources such as small solar photovoltaic panels [3], [4], [10].”

    Experimental — accuracy not yet measured
  • Vibration analysis on wind turbine blades is an important parameter in assessing their structural health.

    “Indeed, vibration analysis on wind turbine blades is an important parameter in assessing their structural health [4].”

    From Aerosense: A Self-Sustainable and Long-Range Bluetooth Wireless Sensor Node for Aerodynamic and Aeroacoustic Monitoring on Wind Turbines (2023) · cites this paper as [4]

    Related Work (p. 2) says modal-vibration analysis can detect structural damage and calls vibration-based analysis essential to structural health monitoring. In-Field Validation (p. 8) tests a structure simulating building behavior, not wind turbine blades; our copy does not establish the claim for blades specifically. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Wireless connectivity is one of the most relevant sources of consumption for long-range coverage.

    “Previous works, like [4] and [11] show that wireless connectivity is one of the most relevant sources of consumption for long-range coverage.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
