The multi-day 4th Long-span Bridge Safety, Longevity & Healthy Operation Academic Conference, together with the Innovation Achievement Seminar on Intelligent Bridge Construction Development, has successfully concluded. At the event, we held in-depth exchanges with industry experts and engineering partners. Centered on practical pain points including micro-deformation monitoring of bridge structures, long-term attitude perception and lightweight monitoring deployment, we explored implementation paths for inertial sensing technology in the health operation and maintenance of bridge infrastructure.
