Intelligent cable with built-in sensor and sensor packaging method

Abstract

The invention discloses an intelligent cable with a built-in sensor and a sensor packaging method. The intelligent cable with the built-in sensor comprises a cable body, a substrate made of a metal material and the sensor with a metalized surface. The shell of the end part of the cable is stripped to expose the steel wire within the cable. The substrate is welded and fixed on the steel wire, the sensor is welded and fixed on the substrate, and the measurement direction of the sensor is the same as the axial direction of the cable. After the surface of the sensor is metalized, the metalized sensor is welded on the substrate, and the substrate is welded on the steel wire, so that the sensor can be packaged in the cable, and finally, the exposed part of the sensor, the substrate and the steelwire are subjected to corrosion prevention. Compared with a traditional bonding and mechanical connection mode, the intelligent cable with the built-in sensor and the sensor packaging method have theadvantages that the service life of the sensor is remarkably prolonged, and full-life monitoring of the state of the cable is achieved. Meanwhile, the structure of the steel wire is not damaged, andthe service life of the cable is not shortened.

Description

technical field [0001] The invention relates to the technical field of intelligent cables, in particular to an intelligent cable with a built-in sensor and a sensor packaging method. Background technique [0002] Stay cables, main cables and suspenders are the main stress-bearing components of cable-bearing bridge structures. They are under high-stress cyclic fatigue loads for a long time. Their cross-sectional dimensions are small and they are very sensitive to corrosion. Once there is disease and deterioration due to the lack of durability and safety of the stay cables or slings, the loss of the bridge's bearing capacity will lead to a vicious accident of collapse, resulting in bad social impact and huge economic losses. In order to ensure the safe operation of the bridge, it is necessary to carry out preventive maintenance and safety inspection on the stay cables, main cables and suspension cables of the cable-bearing bridge. [0003] Smart cable technology is a new tech...

Problems solved by technology

[0005] Based on this, it is necessary to provide a smart cable with a built-in sensor and a sensor packaging method for the problem that the traditional partial implantation method has a low sensor life and cannot realize the full life monitoring of the cable state.
