【摘要】：海上石油运输作为一种经济运输方式的同时,也存在着溢油风险。尤其在船舶进出港及在码头装卸期间发生溢油事故将造成极大的经济损失。港口溢油监测报警系统可以对港口水域进行全天候监测,它可在第一时间发现溢油事故并发出报警。但是目前海事局等港口水域监管部门无法获得溢油监测数值、监测图片和报警信息等数据,并且无法掌握溢油设备的使用情况等信息。同时目前的溢油监测设备使用的DTU模块均由第三方提供通信链路接入溢油监测系统客户端,存在一定安全风险。所以需要开发一套港口溢油DTU数据管理平台,对港口溢油进行实时监测,提供针对溢油监测数据的数据传输链路,并实时监测各码头溢油监测设备数据,为溢油监测设备的使用监督和监测数据管理提供服务,做到事故及时发现及时处理。本文分析了溢油监测数据的特点以及目前溢油监测数据管理存在的问题,提出了建立港口溢油DTU数据管理平台的需求并设计了系统的架构和主要功能。设计并实现了溢油数据中心子系统,实现了溢油监测数据传输、荧光值数据解析及图像重组等功能。利用滑动窗口实现对溢油荧光值数据压缩存储,利用分段常值法实现了报警阈值的动态计算。设计并实现了数据管理平台子系统,基于WebSocket技术实现了溢油监测数据和报警信息的实时展示,并实现了对历史监测数据和港口溢油监测设备基本信息的管理功能。本文最后对系统进行了功能实验和系统稳定性实验。功能实验表明港口溢油DTU数据管理平台可以实现溢油监测数据的传输、实时监测和报警展示等功能,同时实现了对溢油监测数据的管理功能。稳定性实验表明港口溢油DTU数据管理平台可以在大量连接存在的情况下稳定工作并保持良好性能,系统可以协助海事管理部门完善港口溢油监测体系,提升港口溢油监测水平。
[Abstract]:As an economic mode of transportation, oil transportation by sea is at the same time, There is also the risk of oil spills, especially in and out of the port and during the loading and unloading of the wharf will cause great economic losses. The port oil spill monitoring alarm system can be used to monitor the port waters all the time. It can detect oil spill accidents and give an alarm at the first time. But at present, the supervision authorities of ports and waters such as the Maritime Safety Bureau cannot obtain the oil spill monitoring values, monitoring pictures and warning information and other data. At the same time, the DTU modules used by the oil spill monitoring equipment are all provided by the third party to provide communication links to the oil spill monitoring system client. Therefore, it is necessary to develop a set of port oil spill DTU data management platform, to monitor the oil spill in the port in real time, to provide the data transmission link for oil spill monitoring data, and to monitor the oil spill monitoring equipment data of each terminal in real time. In order to provide services for monitoring and monitoring data management of oil spill monitoring equipment and timely detection and handling of accidents, this paper analyzes the characteristics of oil spill monitoring data and the problems existing in the management of oil spill monitoring data at present. The requirement of establishing port oil spill DTU data management platform is put forward, and the structure and main functions of the system are designed and implemented. The subsystem of oil spill data center is designed and realized, and the oil spill monitoring data transmission is realized. Using sliding window to compress and store oil spill fluorescence value data, using piecewise constant value method to realize dynamic calculation of alarm threshold, designing and realizing the subsystem of data management platform. The real-time display of oil spill monitoring data and alarm information is realized based on WebSocket technology. The management function of the historical monitoring data and the basic information of the port oil spill monitoring equipment is realized. Finally, the function experiment and the system stability experiment of the system are carried out. The functional experiment shows that the port oil spill DTU data management platform is based on the system. Can realize the oil spill monitoring data transmission, At the same time, the management function of oil spill monitoring data is realized. The stability experiment shows that the port oil spill DTU data management platform can work stably and maintain good performance when a large number of connections exist. The system can help maritime management to improve port oil spill monitoring system and improve port oil spill monitoring level.
