Description

technical field [0001] The invention belongs to the technical field of marine meteorological precipitation measurement, and in particular relates to a deep sea resistance precipitation measurement device and method based on satellite communication positioning. Background technique [0002] Ocean precipitation data is one of the important elements of ocean hydrological observation. Ocean precipitation includes two parameters: rainfall and rain intensity. Rainfall refers to the liquid and solid (after melting) precipitation falling from the sky to the sea surface, without evaporation, infiltration and loss, the depth accumulated on the horizontal surface, the unit of rainfall is mm, and the rainfall per unit time is called rain intensity , the unit is mm / h or mm / min. [0003] The precise measurement and forecasting of precipitation (rainfall and rain intensity) in deep and open seas is of great significance to ocean shipping, scientific research, disaster prevention and mitig...

Problems solved by technology

The main body of the tipping bucket precipitation measuring instrument is composed of a water receiver, an upper tipping bucket, a collection funnel, a measuring tipping bucket, and a reed switch. This kind of instrument has many parts, a complex structure, and expensive equipment, and is prone to component blockage and errors. Problems such as growth and data loss

The main body of the siphon type precipitation measuring instrument is composed of a water receiver, a float chamber, a self-recording pen, a siphon tube and a casing, etc. This kind of instrument has disadvantages such as a delay in starting the siphon, fuzzy lines drawn by the self-recording pen, and broken lines.

In addition, both tipping bucket and siphon precipitation measuring instruments require the measuring table to be stationary, otherwise it is easy to cause the tipping bucket to turn over by mistake or random siphon drainage during the measurement work, resulting in wrong measurement data. At the same time, the components of these two types of precipitation measuring instruments Corrosion resistance is poor, not suitable for strong corrosion environments such as marine salt spray
