Abstract

The invention discloses a linear array CCD (Charge Coupled Device)-based mooring force monitoring device for a mooring rope. The device comprises two clamping devices, a mooring force monitoring device and a data terminal processor, wherein the two clamping devices are arranged on a mooring rope to be monitored in a sleeving manner; a marking grid painted with a fluorescent dye is drawn on the mooring rope to be monitored between the two clamping devices; the mooring force monitoring device comprises a light source, a power supply, a CCD camera and a signal processor; the CCD camera detects and acquires a marking grid deformation visual signal and transmits the visual signal to the signal processor; the signal processor converts the visual signal into a digital signal; the data terminal processor is in data connection with the signal processor through wireless communication equipment; an overall longitudinal vector S of the mooring rope is acquired by calculating an average deformationamount of multiple groups of marking grids; and a corresponding mooring force F of the mooring rope is obtained according to an S-F curve of the mooring rope. The device disclosed by the invention isrelatively high in stability and high in monitoring precision; under the condition of not damaging a mooring rope structure, the deformation and the tension of the mooring rope can be monitored in real time in a construction process, so that the potential safety hazard is eliminated; and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of cable force monitoring, in particular to a cable force monitoring device based on a linear array CCD. Background technique [0002] As a tool for fixing, bearing, supporting, connecting and transporting, cables are widely used in the fields of marine engineering, civil engineering and transportation engineering. The structural form of the cable includes catenary system, tension system, anchor cable system, etc. in the field of ocean engineering, and space cable network structure, planar cable truss structure, etc. in the field of civil engineering. Cables are important structural components in engineering facilities. Due to the relatively simple structure of the cable, it is used in fields with high safety requirements. In the process of stretching, impact resistance, etc., the deformation of the cable is too large and the cable is broken. Therefore, it is very important to monitor the force and deformation of the...
