[0003]
The offshore platform vibration acquisition and analysis system effectively guarantees the safe operation of the offshore platform, but there is a high demand for high-throughput data analysis. Due to factors such as space and maintenance, the cloud server layout of the offshore platform is limited, resulting in data analysis. The process is slow, which may cause a delay in sending the emergency shutdown signal to the corresponding rotating machinery equipment, seriously affecting the operating efficiency of the offshore platform vibration analysis system

The invention relates to a maritime engineering platform vibration monitoring analysis method and system, and relates to the technical field of maritime engineering platforms, and the method comprises the following steps: setting a plurality of vibration sensors with the same number in each to-be-measured cabin of a maritime engineering platform according to the same number sequence and the same layout; within a preset time period, according to the monitoring condition of each vibration sensor, calculating to obtain a vibration power spectrum data set corresponding to each to-be-measured cabin; calculating an average value according to each vibration power spectrum data set to obtain a standard power spectrum data set; calculating a data set error corresponding to each vibration power spectrum data set and the standard power spectrum data. According to the invention, the vibration condition of each to-be-tested cabin is compared with the average value, so that the vibration influence of each to-be-tested cabin on the whole maritime work platform can be mastered conveniently and quickly and is used as a judgment basis for judging the working condition of equipment in the to-be-tested cabin.
Description
technical field [0001] This application relates to the technical field of offshore engineering platforms, in particular to a vibration monitoring and analysis method and system for offshore engineering platforms. Background technique [0002] Along with the demand for intelligent development, modern offshore engineering platforms generally deploy hundreds or even thousands of vibration sensors on site to conduct comprehensive vibration monitoring of rotating machinery and equipment, and perform power spectrum analysis on the monitoring data on the cloud server. When the power spectrum of the rotating mechanical equipment is abnormal, an alarm signal will be sent and an emergency shutdown signal will be sent after the operator confirms, so as to ensure the safety of personnel and equipment. [0003] The offshore platform vibration acquisition and analysis system effectively guarantees the safe operation of the offshore platform, but there is a high demand for high-throughput ...
