Problems solved by technology

[0003] The quality of marine environmental monitoring data directly affects the scientific nature of marine environmental management decisions. At present, there is no systematic quality control method for marine environmental monitoring data in China. Manual correction is generally used for control. For a large number of marine environmental monitoring data, according to experts Experience, historical data and common sense form a data inspection standard library, and dynamically adjust the inspection standard library according to the conditions of different sea areas

Embodiment Construction

[0009] The invention discloses a marine environment monitoring data management system, and the implementation manner will be described below in conjunction with the accompanying drawings.

[0010] Please refer to figure 1 . figure 1 It is a structure diagram of the management system of ocean environment monitoring data of the present invention. Including data acquisition, data storage, data inspection, uncertainty data management, data analysis, and data display six functional modules.

[0011] The data acquisition module includes meteorological sensors and hydrological sensors. Meteorological sensors collect meteorological data, including wind speed and direction, rainfall, humidity, air pressure, air temperature, etc. Hydrological sensors include tide level and temperature and salinity sensors, which collect tide level data, temperature and salinity data, etc. There are also radioactive monitoring, mussel monitoring, mariculture area monitoring, marine protected area monit...

Abstract

The invention provides a ULDB (Databases with Uncertainty and Lineage)-based marine environmental monitored data management system, which comprises six functional modules respectively for data acquisition, data storage, data detection, uncertainty data management, data analysis and data display. The quality of marine environmental monitored data directly influences the scientificity of marine environmental management decisions. In the system, uncertainty data in a marine environmental monitoring domain is stored by adopting ULDB, the source of the uncertainty data is searched according to a lineage function, top-k query semantics is defined according to user requirements and business characteristics, and thus, different requirements of users are satisfied. The system can effectively utilize the marine environmental monitored data to provide scientific support for the marine environmental management decisions.

Description

technical field [0001] The invention relates to a quality control method of marine environment monitoring data, and an uncertainty data storage and query algorithm. Background technique [0002] In view of the increasing perfection of the global marine environment monitoring system and the strengthening of my country's marine environment monitoring, how to use the marine environment monitoring data more efficiently, improve the quality control efficiency and level of the marine environment monitoring data, and store and query the uncertain data , to guide the scientific and standardization of marine environmental monitoring business processes, and provide strong support for my country's digital ocean construction, it is necessary to establish a marine environmental monitoring data management system. [0003] The quality of marine environmental monitoring data directly affects the scientific nature of marine environmental management decisions. At present, there is no systemati...
