Abstract

The invention discloses an automatic satellite synchronization surface layer columnar water sample collection system and an automatic satellite synchronization surface layer columnar water sample collection device. The automatic collection system comprises a cloud detection module, an overlay analysis module, a command generation module, a short message receiving-transmitting module, a short message controller, a micro electric windlass and a sampling device, wherein the short message controller receives a sampling command short message to drive the micro electric windlass, and the micro electric windlass drives the sampling device to sample water; the sampling device comprises a sampler and a hoisting mechanism. By adopting the automatic satellite synchronization surface layer columnar water sample collection system, the automatic sampling is realized; the sampling device is simple in structure and few in moving parts, has no precise element, is sealed in an elastic film torsion manner and is low in cost, reliable in action, easy to maintain and suitable for long-time field guard and multi-point installation and layout; the pollution of lake water for the sampler can be avoided, the interference of the sampler for planktons on the surface layer of the water also can be avoided, and the reliability of a sample can be improved.

Description

technical field [0001] The invention relates to a satellite synchronous surface columnar water sample automatic collection system and a sampling device, belonging to the technical field of automatic water sample collection. Background technique [0002] In the field of satellite water color remote sensing inversion, water samples in the study area need to be collected for inversion modeling and inversion model verification. Sampling for satellite water color remote sensing needs to meet four basic requirements: [0003] In terms of time, to ensure synchronization, the satellite image and the ground objects within the sampling time interval cannot have significant changes. Water quality indicators, especially plankton, change rapidly, and sometimes the distribution concentration will change significantly within ten minutes. Therefore, it is generally required to collect surface water samples within half an hour of satellite transit to ensure the synchronization of satellite...

AI Technical Summary

Problems solved by technology

These two types of sampling methods cannot be used for quantitative analysis of plankton distribution because they only collect plankton and do not collect water samples.

[0010] The response speed of automatic sampling is fast, which can meet the requirements of satellite remote sensing in terms of time. However, the current automatic water quality sampling equipment can only collect samples below the water surface, and cannot obtain surface water samples.

The water pump used in automatic water sample collection equipment can easily damage the distribution structure of surface plankton and affect the reliability of laboratory analysis results
