Description
Technical Field
[0001] The utility model relates to the field of aquatic organism detection equipment, in particular to a portable plankton rapid detection device. Background Art
[0002] The detection of aquatic plankton is of great significance to ecological and environmental protection. Plankton is the primary producer of aquatic ecosystems. In recent years, the Ministry of Ecology and Environment and the Ministry of Water Resources have successively launched a number of standards and guiding documents to regulate the identification and research of plankton. The classification and counting statistics of microscopic aquatic organisms can scientifically and effectively evaluate the aquatic ecology of water bodies. At present, there is no portable plankton detection equipment based on computer image recognition on the market. Most of them detect plankton through fluorescence or chemical reactions. This type of portable equipment can only measure phytoplankton to the door, and cannot determine the genus or species required by national standards. The counting often shows large errors and cannot meet the business needs of the monitoring department. Although the existing laboratory version of the plankton monitoring equipment based on artificial intelligence identification can detect genera or species according to national standards, it is relatively bulky and cannot be carried and moved. When faced with sudden water environment and water ecological imbalance problems, it is unable to quickly reach the site for detection. Moreover, some monitoring equipment on the market cannot be adjusted in direction according to the observation range during use, resulting in limitations in the detection process. Therefore, it is of great application significance to develop a portable plankton rapid detection device with a simple structure, easy use, small size, light weight, and a translation base that can achieve a large observation range at one time.
