The invention discloses a displacement sensing system for an offshore multi-floating-body flexible connection structure, which is connected between two adjacent offshore floating bodies and consists of two Hall displacement sensors with the same structure and a stay wire connected between the two Hall displacement sensors, the end, close to the signal analysis device shell, of a center shaft in the stay wire magnetic variation device shell is connected with a permanent magnet disc through a bearing, a plurality of permanent magnets are evenly arranged on the disc face, facing the signal analysis device shell, of the permanent magnet disc in the circumferential direction, and one end of a hollow rotating shaft is fixedly connected to the disc face opposite to the permanent magnet disc. A self-coiling spring is tightly sleeved in the hollow rotating shaft, the center shaft is sleeved with the self-coiling spring with a gap, and the two ends of a stay wire are wound on the outer ring of the hollow rotating shaft of one Hall displacement sensor respectively; a Hall chip array is fixedly attached to the disc face, facing the permanent magnet disc, of a Hall disc in the signal analysis device shell, and a Hall encoder converts electric signals measured by the Hall chip array into displacement signals and records the displacement signals.

    本发明公开一种针对海上多浮体柔性连接结构的位移传感系统,其连接于相邻两个海上浮体之间,由两个结构相同的霍尔位移传感器与连接于两个霍尔位移传感器之间的一根拉线构成,拉线磁变装置外壳内部的中心轴在靠近信号分析装置外壳的一端通过轴承连接永磁体圆盘,永磁体圆盘在面对信号分析装置外壳的盘面上沿圆周方向均匀布置若干个永磁体,在背对的盘面上固定连接空心转轴一端,空心转轴内部紧密套有自卷弹簧,自卷弹簧有间隙套在中心轴外,拉线的两端分别缠绕在一个霍尔位移传感器的空心转轴外圈上;信号分析装置外壳内部的霍尔圆盘在面对永磁体圆盘的盘面上固定贴有霍尔芯片阵列,霍尔编码器将霍尔芯片阵列测得电信号转化为位移信号并记录。
