Water area water quality abnormal point detecting and pre-warning method

Abstract

The invention belongs to the field of water quality monitoring. The purpose of the invention is to provide a water area water quality abnormal point detecting and pre-warning method which has very high detection accuracy and degree of intelligence. According to the technical scheme, the water area water quality abnormal point detecting and pre-warning method comprises the following steps: (a) intelligent cruise; (b) monitoring data model analysis; (c) suspected abnormal data point check; and (d) abnormal data point on-site water sample collection. According to the method, an intelligent cruise ship is used as a carrier, a water quality abnormality analysis model serves as a software support, and human-computer interaction is performed based on the Internet-of-things technology. Water quality abnormal point detecting and pre-warning is truly realized.

Description

technical field [0001] The invention belongs to the field of water quality monitoring, and in particular relates to a method for detecting and early warning of water quality abnormal points in water areas. Background technique [0002] Pollution of surface waters is currently an important issue for environmental protection, and the compliance of corresponding water sections is the main goal of the environmental protection work of local governments. However, the surface waters are vast, and it is difficult for fixed-point water quality monitoring stations to have a more detailed understanding of the spatial changes of large water areas, which brings many practical difficulties to the research on the mechanism of water quality changes in water areas. At the same time, many waters have seen the phenomenon of illegal sewage discharge, and it is difficult to carry out manual inspections, especially at night. Therefore, grasping the information of water quality changes in large w...

Problems solved by technology

For example, the patent CN 102818884 A published "a method for locating illegal sewage outlets". The river cruise is a fish-shaped robot, which does not form an intelligent mobile function, so that it is impossible to carry out intelligent cruise in the corresponding waters, so it is difficult to check potential sewage points. ; At the same time, the mobile monitoring component described in the patent has built-in minimum standard parameters for normal water quality

In reality, any water quality data in the water area may have changes such as day and night differences in one day and seasonal differences in four seasons. There is no fixed minimum standard parameter, and the corresponding comparison reference value at a specific time can only be obtained through an empirical model; at the same time, there is a lack of information review. functions, especially the information feedback function, cannot realize early warning and on-site verification of corresponding phenomena
