Three-dimensional layered water quality monitoring method and three-dimensional layered water quality monitoring system

Abstract

The invention provides a three-dimensional layered water quality monitoring method and a three-dimensional layered water quality monitoring system. The method comprises the following steps of collecting water quality information of each measurement point, calculating mean square deviation of water quality parameters of each measurement point in real time, and collecting positions underwater according to the mean square deviation value; automatically controlling the underwater collection speed according to the water-level fluctuation speed; and collecting water quality information at different underwater depths according to the mean square deviation of water quality information, measurement points with water-level fluctuation selective adaptability and underwater speed, and establishing water body information in a layered manner. The system comprises a lifting execution device, an underwater collection device arranged on the lifting execution device, and an overwater control device respectively connected with the lifting execution device and the underwater collection device. The method and the system are capable of automatically and accurately monitoring ocean water quality or surface water quality, intelligently controlling the collection depth, speed and interval, accurately, effectively and automatically dividing each water layer along the direction, and providing accurate and reliable data guarantee for water quality research.

Description

technical field [0001] The invention relates to the technical field of ocean or surface water quality monitoring, in particular to a three-dimensional layered monitoring method and system for water quality. Background technique [0002] Water in nature is the foundation of plant growth and one of the essential factors for human survival. Among them, ocean water and surface water have seasonal stratification due to the influence of water temperature and other factors. Different, it can be divided into thermocline, halocline, oxygen-enriched layer, low-oxygen zone and anoxic zone, etc., and the water body temperature, dissolved oxygen concentration, pH value, electrical conductivity and chlorophyll in each layer are all the same. It provides an important basis for people to comprehensively analyze the layered structure of water bodies and the three-dimensional distribution of water quality. Therefore, how to monitor the vertical distribution of water quality in ocean water or ...

Problems solved by technology

[0003] At present, the monitoring method for water quality is to use the traditional buoy data acquisition controller to collect water quality parameters at fixed water depths. This method cannot automatically, comprehensively and accurately collect water quality parameters at different depths underwater, which will cause the monitoring data to not be updated in time. Affects the accuracy of research on water quality
