Background The roll-on/roll-off automobile carrier is an important specialized ship type in a modern logistics system, and a stern springboard is used as a key channel for connecting a wharf and a cabin and bears the core functions of boarding and disembarking vehicles and cargoes. The stern springboard is usually formed by hinging a plurality of sections of springboards, the structural strength of the stern springboard is generally designed according to the preset maximum overground load, and the safety redundancy is limited. In the actual operation process, the weight of the actual over-refuted goods exceeds the original design load of the gangway due to various goods types and complex loading working conditions. On the one hand, under the overload working condition, the pressure of the gangway on the wharf is too high, the surface of the wharf is easy to damage, on the other hand, the local stress of the gangway body, particularly the joints of each section, can be obviously exceeded, the long-term accumulation can lead to structural fatigue damage, and even the gangway is deformed or broken when serious, so that the normal operation and navigation safety of the ship are affected. In the prior art, for improving the capability of the springboard for passing the barge, a passive reinforcement mode is generally adopted, such as increasing the structural strength of the springboard, replacing high-specification materials and the like, but the modes have high transformation cost and long implementation period, and the sudden overload working condition cannot be dynamically dealt with on the premise of not interrupting the operation. In addition, the traditional springboard lacks a real-time stress monitoring and active regulation means, so that operators cannot timely master the real-time bearing state of the springboard, and the real-time bearing state can only be judged by experience, so that the hidden danger is large.
