Method for monitoring safety of ocean platform on basis of displacement sensors

The invention relates to a method for monitoring the safety of an ocean platform on the basis of displacement sensors and belongs to the technical field of ocean platform monitoring. The method comprises the following steps of (1) calculating and analyzing the whole different working conditions of the ocean platform, and establishing a database by a finite element analysis software; (2) designing a pre-alarm system according to the displacement of the central point of a deck, equipment or operation restrictions, and extreme operating conditions on the ocean platform; (3) arranging the displacement sensors; (4) acquiring and transmitting data of the displacement sensors; (5) establishing a signal demodulation control system to facilitate the analysis and the processing of a computer, wherein the control system is used for controlling and managing the equipment; and (6) importing the data into the database, establishing an estimating system, and reflecting the safety status of the whole structure of the platform in real time by monitoring, analyzing and processing position signal data. An estimating way is simplified by the method, the method has the characteristics of monitoring in real time, wide application range, high monitoring precision and the like, and the safety of the structure of the ocean platform can be intelligently and accurately monitored and pre-alarmed.
