With the development of offshore oil resources,the operational safety and efficiency of off-shore oil production platforms have become the focus of attention in the industry.An innovative moni-toring solution is explored,an instrumentation system based on wireless sensor networks(WSN),which aims to provide a high precision,low energy consumption and stable monitoring platform for offshore operating environments.The system improves the efficiency of data acquisition and transmis-sion by elaborately designed network hierarchy,adaptive routing algorithm and data processing tech-nology.Through encryption technology and fault self-healing mechanism,data security and system re-liability are ensured.Through the case analysis of a specific offshore platform,this paper shows the practical application effect of the system,which provides a strong support for the intelligent manage-ment of offshore oil production platform.
