Description

Technical Field

[0001] This utility model relates to the field of cable force monitoring technology, and in particular to an integrated cable-free cable force monitoring device. Background Technology

[0002] The cable tension status is an important indicator of whether a bridge is in normal operating condition. Cable tension monitoring provides a basis for overall assessment of the bridge's safety and durability. Under operating conditions, accurately grasping the cable tension distribution and changes helps monitor the cable tension status, analyze the impact of cable tension on the internal forces of the cable-stayed bridge structure, correctly guide cable tension correction, and serve as a basis for long-term health and safety monitoring.

[0003] In existing cable stress monitoring solutions, vibration sensors and data acquisition equipment are separate structures. During on-site construction, it is necessary to run cables to connect the data acquisition equipment and vibration sensors. Furthermore, the data acquisition equipment also requires its own power supply and network, making on-site construction difficult. At the same time, installing vibration sensors on the cables makes wiring difficult. Utility Model Content
