Radar wireless transmission tidal level early warning and alarming equipment
Technical field
The utility model relates to ocean tidal level and measures and early-warning and predicting observation technology field, specifically a kind of radar remote transmission tidal level early warning and alarming equipment.
Background technology
Tidal level observation and early-warning and predicting are one of ocean observation station mainly observation projects, simultaneously in a lot of practical application, such as: bathymetric survey, environmental evaluation and marine usage project also need to carry out tidal level observation in short-term, especially need the tidal level of point (early warning position) more to observe for the tidal level early-warning and predicting in marine disaster prevention and reduction.Problems of the prior art lack the measuring equipment being exclusively used in tidal level early warning on the one hand, on the other hand existing tidal level scope is comparatively large for installation difficulty during silt coast, the third aspect be lack not only easy to use but also there is the measuring equipment of low maintenance or non-maintaining and long-range real-time Transmission.
The tidal level scope of frequent employing is divided three classes:
(1) float-type tidal level scope.This kind equipment is used first to need larger capital construction to drop into, be difficult to build observation station at alluvial coastal and need vertical shaft, the alluvial of process vertical shaft also will be the work not easily completed, and this defect greatly limit the use of float-type tidal level scope at silt coast;
