A device for early warning structure damage based on stress monitoring

Abstract

The invention discloses a device for early warning structure damage based on stress monitoring, which includes a mobile terminal, a data processor, and a net. The top of the net is connected to a top frame, and the bottom of the net is provided with a bottom frame. The bottom surface of the bottom frame is connected to the periphery of the top frame. The lower edge is connected with a cable, the cable is braided by multiple strands, and the fiber is braided inside the cable, and the bottom of the optical fiber is covered with a protective case. The protective case includes a top cover, which is connected to the shell through threads. The top is symmetrically provided with an anti-wear sealing ring, and at least one fixed shaft is arranged longitudinally inside the housing, and each fixed shaft is covered with a rotating shaft outside, and a rubber layer is adhered to the inner wall of the housing. The device monitors the tension of the cable in real time through the impact of waves and currents on the cable, and makes decisions on the tension of the cable through the data obtained through monitoring, so as to avoid economic losses caused by the breakage of the cable due to the force exceeding its carrying capacity.

Description

technical field [0001] The invention belongs to the technical field of monitoring and early warning, and in particular relates to a device for early warning of structural damage based on stress monitoring. Background technique [0002] The cable is an indispensable stress element and safety guarantee in marine breeding projects and various engineering constructions. The stress of the cable will greatly affect the safety of life, breeding safety and breeding benefits. Therefore, it is particularly important to monitor the tension of the cable . [0003] At present, the deformation monitoring of pipelines or cables is limited to small deformations, and resistive or capacitive devices are mostly used for fixed-point measurement. This kind of measurement system has a large volume, so it has a great influence on the structure of the monitored object, and at the same time, the measurement accuracy for large deformation cannot meet the positioning requirements. At the same time, ...

This kind of measurement system has a large volume, so it has a great impact on the structure of the monitored object, and at the same time, the measurement accuracy for large deformation cannot meet the positioning requirements

At the same time, the positioning system of underwater robots is based on acoustics. This system is complex to operate, and has the disadvantages of slow update rate, poor robustness to coastal noise interference, and poor autonomy.
