Description

technical field [0001] The invention belongs to the application of technologies such as mechanics, hydraulic pressure and embedded systems in cable tension measurement, and is particularly suitable for tension detection devices in space structures such as cable-stayed bridges, suspension bridges, hoists, aerial ropeways, and high-voltage electric wires. Background technique [0002] Many modern engineering facilities use the tension of cables to support loads, such as cable-stayed bridges, suspension bridges, hoists, aerial ropeways, high-voltage wires, etc. Cable structures play a key role in such load bearing actions. In order to ensure the safety of such structures, accurate and rapid measurement of cable stress has become an important link in the later maintenance of engineering facilities. Cable force measurement provides an effective means for monitoring the force of the cable structure at any time, evaluating the technical status of the structure and discovering pote...
