The Model of Simply Supported Beam Force Monitoring Based on Inertial Internet of Things

Deformation and fracture of packaging hanging beams caused by force will bring death and immeasurable damage. However, the traditional methods are not suitable for the existing structures. Aim to the deformation and stress analysis of simply supported beam model, packaging hanging beams and bridges, the inertial sensor is adopted to design a force deformation monitoring model of hoisting simply supported beam in this paper. The model monitors the angle change of the sensor placed at the two fulcrum of the beam arm. The influence of internal and external factors on angle change measurement was removed by filtering, and the deflection curve equation and the other equations of beam arm are constructed by combining length of beam arm and bending stiffness EIz. The force size, maximum deflection value and the other parameters of the beam can be obtained through the angle change of two fulcrum, and the force deformation of the beam can be monitored in real time at the embedded terminal and PC terminal. The force deformation simulation of the method and model was given, and the simply supported beam model of the steel ruler was used for testing. The error of stress and stress position was ±0.5N and ±0.1CM. And the maximum deflection and stress position was ±0.5N and ±0.5CM. It shows that the computed bending rigidity was consistent with reality. And it's proves that the method can better realize the measurement of existing structures.
