The invention belongs to the technical field of ship safety monitoring, and particularly relates to a ship structure state long-term monitoring system. The ship body total longitudinal stress testing unit measures the deformation amount of the ship body structure in real time; the ship body vibration test unit monitors the ship bow acceleration and tests ship body vibration data; testing the overall rolling and pitching angle data of the ship body through a ship body motion testing unit; monitoring stress-strain information of a dangerous position of the ship body in real time through a ship body local stress testing unit; the total longitudinal bending moment, the transverse bending moment, the double torque and the size and direction of the torque acting on the cross section of each needed shipping space of the ship body structure are obtained through calculation of the main control center and compared with preset threshold values, and if the ship body is in a dangerous stress state, early warning is conducted through the alarm unit. The device has the advantages of being simple in structure, convenient to install, accurate in measurement, free of temperature drift and the like, and is suitable for monitoring structural deformation and stress states of the container ship in the loading, unloading and shipping processes for a long time.
本发明属于船舶安全监测技术领域,具体涉及一种船体结构状态长期监测系统。本发明通过船体总纵应力测试单元实时测量船体结构的变形量;通过船体振动测试单元监测船艏加速度,测试船体振动数据;通过船体运动测试单元测试船体总体横摇以及纵摇角度数据;通过船体局部应力测试单元实时监测船体危险位置的应力应变信息;通过主控中心计算得到作用于船体结构每个所需舱位横剖面的总纵弯矩、横向弯矩、双力矩以及扭矩的大小和方向,并与提前设定的阈值进行比较,若处于危险应力状态则通过报警单元进行预警。本发明具有结构简单、安装方便、测量准确和无温漂等优点,适用于长期监测集装箱船装载、卸载以及航运过程中结构的变形及应力状态。
