Unmanned ship

Technical Field

The invention belongs to the technical field of unmanned ships, and particularly relates to an unmanned ship.

Background

Water is a source of life and one of the most important substances on which humans depend for survival. With the rapid development of economy, the expansion of population and the reduction of self-purification capability of rivers and lakes in China, rivers and lakes in China are generally polluted to different degrees, and 75 percent of lakes in China are eutrophicated to different degrees. The water pollution reduces the use function of the water body, aggravates the shortage of water resources and brings negative effects to the implementation of the strategy of sustainable development in China. The monitoring and early warning of the water quality are enhanced, and the water pollution is prevented and treated in time.

In order to ensure the water standard of industrial water, agricultural water and drinking water and solve the problem of water pollution, the most important is to improve the water quality monitoring capability. The water quality monitoring can find the source of the problem as soon as possible before the water body is seriously polluted, and corresponding measures are taken for treatment. The traditional water quality monitoring mode which takes manual on-site sampling and laboratory instrument analysis as main means has the defects of low monitoring frequency, small monitoring range and the like, cannot reflect the pollution change condition in time in a large range and high frequency, even cannot carry out efficient and quick emergency monitoring on sudden water quality pollution events, and is difficult to meet the requirement of effective environmental management of governments and enterprises. In the water quality monitoring process, the system is expected to automatically inspect the water quality in the water area all day long, and can quickly arrive at a destination to acquire field water quality data after an emergent water quality pollution event, and dynamically transmit the data to an upper monitoring master station system in real time so as to perform intelligent prediction, early warning and information release of the water quality condition.
