Automatic imaging device and method of underwater planktons

Abstract

The invention discloses an automatic imaging device and method of underwater planktons. The device comprises a fluid module, an imaging module, a control module and the like, wherein the fluid modulecomprises a sample pump, a first container, a second container and the like; the sample pump comprises an injector, a distribution valve and a control system; an inlet / outlet of the injector is communicated with a first inlet / outlet of the distribution valve; a second inlet / outlet is used as a sampling opening; a third inlet / outlet is communicated with a first inlet of the first container; the first container is communicated with the second container through a circulating tank; an outlet of the second container is communicated with a first filter, a mini-type sheath flow pump, a second filterand the first container in sequence; the circulating tank is arranged in a visual field of the imaging module; a control system, the mini-type sheath flow pump and the imaging module are electricallyconnected with the control module. By adopting the automatic imaging device and method provided by the invention capable of automatically photographing underwater planktons and processing the data fora long period, a solution is provided for long-period observation of the underwater planktons and early warning of harmful microorganisms.

Description

technical field [0001] The invention relates to the technical field of plankton sampling and detection, in particular to an underwater plankton automatic imaging device and an imaging method. Background technique [0002] Marine plankton occupies an extremely important position in the marine ecosystem, and its quantity change and spatial distribution will have an important impact on the marine ecosystem and even global climate change. [0003] At present, there are already some marine plankton analysis devices that involve imaging, but they focus more on the analysis of the overall plankton combined with characteristic information such as fluorescence. Some biota were imaged without even being able to ensure that some of these individual plankton individuals were imaged in their entirety. In addition, traditional plankton detection and imaging methods need to sample and store plankton first, and then bring them back to the laboratory for analysis. During this process, it is...

[0003] At present, there are already some marine plankton analysis devices that involve imaging, but they focus more on the analysis of the overall plankton combined with characteristic information such as fluorescence. Some biota were imaged without even being able to ensure that some of the individual plankton were imaged in their entirety

In addition, traditional plankton detection and imaging methods need to sample and store plankton first, and then bring them back to the laboratory for analysis. During this process, it is inevitable that the samples will be damaged to varying degrees, or some plankton cannot be detected.

Therefore, there will inevitably be omissions in the above sampling and testing process.
