[Abstract]:Offshore platforms are monitored under harsh adverse conditions, such as far from land, harsh environment, extreme weather, poor network conditions, and so on. The current data generated by the monitoring are of various sources, large quantities, fast and real-time, diverse structures, and instantaneous changes. The requirement of management technology is getting higher and higher, and many traditional management methods and models can not meet the demand. How to manage the monitoring flow data of offshore platform scientifically and effectively has less research results and practical experience, which is also the problem to be solved urgently. In this paper, the characteristics and related characteristics of monitoring stream data on offshore platform are summarized. The research status and main problems of remote transmission, standardized processing, distributed storage and management system of stream data at home and abroad are summarized. Based on the feedback mechanism and MD5 code detection, the streaming data remote transmission technology is proposed. The integrity and consistency of stream data transmission are ensured by checking the MD5 code of the data file transmitted by the sender and the MD5 code generated by the receiver. A monitor stream data repair function library and data format information table including all possible data canonical processing methods are established, which can deal with the problems of monitoring stream data error, loss, disorder, noise and so on. Based on Hadoop, a distributed storage platform for monitoring stream data is built, which provides a service for efficient query and analysis of data. In order to meet the practical requirements of practical applications, a data management system for offshore platform monitoring stream is designed. The functions of user management authority, stream data remote transmission, data normalization, distributed data storage, data query and so on are implemented. Through the research on the management of the monitoring current data of the offshore platform, this paper provides some ideas for the management and application of the monitoring current data of the offshore platform, and ensures the safe operation of the offshore platform. It is of great significance to promote the development and application of marine engineering monitoring technology.
