Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Navigation ADCP data quality analysis and reprocessing system of the present invention, such as figure 1 As shown, the system is mainly composed of three parts: information database, visual data processing terminal, and navigation ADCP data reprocessing function module.

[0027] The information database mainly stores flow velocity data measured by navigational ADCP, bottom tracking data, GPS latitude and longitude data, geostrophic flow data measured by AVISO satellite altimeter, other fixed-point flow velocity observation data, tidal current data simulated by high-resolution global tide model, etc. data. The stored information of the information database also includes: data quality analysis record data, data processing related...

Abstract

The invention discloses a cruising ADCP data quality analysis and reprocessing system which consists of an information database, a visualized data processing terminal and a cruising ADCP data reprocessing function module. The information database stores flow speed data detected by a cruising ADCP, bottom tracking data, GPS longitude and latitude data, geostrophic flow data detected by an AVISO satellite altitude meter, other fixed-point flow speed observation data and high-resolution tidal stream data simulated in a global tide way. The visualized data processing terminal has data analysis anddrawing functions. The cruising ADCP data reprocessing function module comprises an ecological plankton module, a suspended matter research module and a spectral analysis module. The cruising ADCP data quality analysis and reprocessing system has the advantages of being visual, simple, clear, easy to operate and good in pertinence and can overcome the shortcomings of big difficulty, low efficiency, lots of errors and low data quality level of an existing cruising ADCP in data processing work.

Description

technical field [0001] The invention relates to the field of marine data analysis, and more specifically, relates to a navigation ADCP data quality analysis and reprocessing system. Background technique [0002] Acoustic Doppler Velocity Profiler (ADCP) can realize the acquisition of continuous and high-frequency flow velocity and flow direction information at different depth layers, and then realize the accurate determination of flow direction and intensity. Compared with traditional flow rate and direction measurement equipment, ADCP has the advantages of fast measurement speed, high precision, and the ability to obtain three-dimensional flow field information. It is currently the most effective method for measuring multi-layer ocean current profiles in the world, and is widely used in marine surveys, ocean engineering, etc. In this field, domestic and foreign oceanographers have done a lot of research on the data processing of ADCP. [0003] However, there are still the ...
