The invention relates to a multi-degree-of-freedom micro-vibration diagnosis method and sensing terminal. Calculation and observation of settlement and displacement values are realized, and credibility analysis is carried out on the settlement and displacement values obtained by calculating data samples acquired at each
acquisition time point, thereby improving the accuracy of an observation result. Through
vibration detection and trigger
data acquisition including acceleration data,
magnetic field data, angle data, positioning data and the like, the sensors are high in
collaboration, the datarelevance at the same time is high, and the dynamic change condition of an
observation point can be reflected in real time. According to the invention, non-contact sensing, edge calculation, data storage,
backup power supply, communication transmission,
encryption chips and the like are realized, a wider acquisition frequency can be freely selected, and micro-vibration and magnetic force change can be freely sensed; and the method and the sensing terminal can be applied to different application scenes such as dangerous buildings, ancient buildings, bridges, underground
pipe galleries, dams, tunnels and iron towers, and provide powerful support for
disaster monitoring and early warning and forecasting in China.
