The application discloses a digital calibration method for an inclinometer based on an intelligent sensor and belongs to the technical field of intelligent sensors, which comprises the following steps: collecting data synchronously by integrating a multi-source environment sensor and an inclinometer, and fusing reference data; the application precisely quantifies the nonlinear coupling contribution of environmental factors such as temperature gradient and vibration spectrum to the inclination error by fusing error perception weighting and principal component dynamic correlation analysis; the application maps the mathematical principal components into interpretable physical interference mechanisms such as temperature change rate and low-frequency vibration, and inversely calculates the original parameter weight, thereby not only identifying key dynamic characteristics but also marking nonlinear sensitive areas, significantly improving the physical interpretability and engineering guidance value of error separation, enabling the subsequent model to targetly inhibit the dominant interference, avoiding the overfitting risk caused by black box modeling, providing a weight basis for confidence evaluation, and greatly enhancing the robustness and adaptability of the calibration system under complex working conditions.

This utility model relates to the field of tilt measurement technology, specifically to a vibrating wire tiltmeter, comprising a housing, inside which are two symmetrically arranged steel wires, each with a support at both ends. The support is divided into an upper support and a lower support, with the ends of the steel wires fixed to the upper and lower support via wire clamps. The lower support is connected to the upper support via an elastic hinge. Support seats are fixed on both sides of the lower support for fixing the coil. A counterweight is fixed at the lower end of the lower support. Utilizing the characteristics of the vibrating wire sensor, namely that its output signal natural frequency is determined only by its physical parameters such as tension, length, and linear density and does not require power supply, this sensor exhibits strong long-term stability, strong anti-interference ability, low temperature drift and zero drift, and minimal influence from electrical parameters, enabling it to adapt to long-term observation and long-distance testing under harsh conditions.
