Marine platform monitoring system and method

Abstract

The invention discloses a marine platform monitoring system, and the system comprises a monitoring host, a host node, and a plurality of onsite monitoring terminals. Each onsite monitoring terminal comprises a data collection node and an acceleration sensor corresponding to the data collection node. The monitoring terminals are absorbed at a plurality of measurement points of a detected marine platform, and complete the collection, storage and wireless transmission of the acceleration data of the marine platform. The monitoring host and the collection nodes achieve the real-time monitoring and analysis of a collection process through a wireless network. Meanwhile, the system achieve the marine platform detection method which comprises a multi-node collection synchronization mechanism and wireless data compressed sensing and takes the data on-orbit calculation which takes the collection data model matching and effective data classification storage as a main part through employing the high-speed and parallel characteristics of an FPGA. The system solves a problem of synchronization between collection nodes and a problem of the power consumption and bandwidth of multi-node wireless transmission, improves the practicality and reliability, reduces the data processing workload, and improves the work efficiency.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and relates to an ocean platform monitoring system and a monitoring method. Background technique [0002] An offshore platform is an offshore structure that can serve as a supporting platform for activities such as offshore drilling, oil production, and observation. Due to its special working environment, the offshore platform structure will be affected by seawater corrosion, all-weather operation, waves, tides, currents, drift ice and earthquakes, sediment erosion, marine biological invasion, etc. during operation, and its resistance attenuation is very obvious , and the failure and damage of the offshore platform structure will not only cause direct heavy economic losses and casualties, but also may cause serious environmental pollution and social and political impact. Therefore, the problem of improving the reliability of offshore platforms and equipment and ensuring the safety of marine o...

AI Technical Summary

Problems solved by technology

On-site sensor installation, cable layout and main structure are carried out simultaneously. There are two problems here: on the one hand, the sensor signal cable is long, and the cable wiring position is sometimes difficult to reach, and the expenditure is several times or even dozens of that of the instrument itself. On the other hand, after the signal cable of the sensor is installed, it faces the problem of finished product protection. Factors such as people walking around and strong winds at sea causing the cable to swing and wind may cause damage to the test system.

Second: The offshore platform is a large structure with a large span and a wide range. The single-point monitoring system cannot accurately and comprehensively reflect the operating conditions of the offshore platform. Therefore, a multi-point monitoring system is needed

It proposes the framework of the wireless monitoring system for offshore platforms, but due to the data processing characteristics of single-chip microcomputers, its parallel processing capability for multi-channel real-time synchronous data is limited
